Drill attachment for mixing mortar, can the rotary hammer be used as a mixer? Varieties of electric construction mixers and attachments for them Construction mixer do-it-yourself drill attachment.

Both the mixer and the electric drill are far from essential items. Not everyone can afford to keep both at home. But even if you can boast of having an electric drill at home, most often it is a powerful kilowatt device that is convenient for drilling walls. But after all, it will be difficult to drill out radio boards or repair shoes with it, right? Therefore, I had the idea to make a special attachment for the mixer, with which now you can not only cook an omelet, but also drill a hole in a hard-to-reach place.

The drill adapter is inserted into the socket of the “high speed knife” attachment. If you have a rubber joint between the mixer and the nozzle, you will have to redo that too. For the effort that he is able to transfer is not enough even for the operation of the coffee grinder. A square is best for joining, but a hexagon is also suitable.

The drawing shows the dimensions of the details of the nozzle for the "MP-2E" mixer produced by the Minsk Electrical Equipment Plant, but due to the similarity of all mixer models, the correction will be quite insignificant. I took the cartridge from a hand drill. You should not count on drills with a diameter of more than 5 mm even when drilling wood (after all, the power of the mixer motor does not exceed 100 W), so if you can choose the chuck, you should choose the smallest possible size.

Diy diagram for making a drill from a mixer

Parts 3 and 4 require production on a lathe; in the absence of a head of the required size for part 3, the groove for the hexagon will have to be milled. In the case of complete production of part 3, a slight improvement can be made, which consists in the following. To eliminate the additional surface of friction between 3 and 4, make a sample for the hexagon with a slope of 5-6 degrees relative to the horizontal axis. This is necessary so that the head, sitting on the hexagon, adheres to it during advancement and is jammed by frictional forces. In this case, there will be a small gap between the head and the bushing, which will prevent additional heating of the unit and the associated loss of power.

Part 4 can be made from any structural steel, but if you can find a piece of polyethylene of the right size, the design will benefit. If structural steel is used, a through hole in the sleeve should be provided for shaft lubrication; the polyethylene sleeve should be lubricated with grease. Typically, the chuck shaft is surface hardened and MB threads should be easy to cut. The nozzle is assembled as follows. A sleeve is put on the chuck shaft, then the head is screwed on. The nozzle assembly is screwed to the mixer along the MLO thread.

The fact that the mixer, unlike most electric drills, has a smooth speed control, which creates additional convenience during operation, also speaks in favor of using the attachment. By the way, maybe you have an old enlarger lying around? In the conditions of the victorious offensive "Kodak" you will hardly need it already, and its tripod can be adapted for a drilling machine. Especially convenient is a tripod with a toothed rack from the UPA enlarger. The adjusting handwheel feeds the drill as smoothly as on a drilling machine. If you have a low-power drill "Master", you can place it on a tripod.

Video instruction - how to make a drill from a mixer

We will need from materials and tools:
1. Aluminum thick wire (In my case - 8mm)
2. Vice.
3. Large pliers or pliers.
4. Pipe ("gas") wrench.
5. "Grinder", chisel, hacksaw for metal, or any other cutting tool to cut the wire.

I am currently building an extension to the house. Before erecting the roof of the extension, I decided to cultivate the pediment of the house, to which, in fact, the extension will adjoin. It turned out that the pediment needed to be painted. Since it was built of brick, I decided to do this with the help of a compressor and a paint spray gun, because it is rather troublesome to paint over deep masonry joints with a roller. I decided to use an acrylic-based water-dispersion facade paint. I specially went to the construction market to buy two things - the paint itself and a mixer, which, by holding it in a drill, can stir this paint when water is added to it. (For this method of application, the paint must be liquid). Arriving at the market, I chose paint, bought it and drove off to the facility ... I forgot about the mixer ...

It turned out that I had forgotten not only about the mixer, but also about the primer - the surface to be painted must first be treated with a deep-penetrating primer ...

Well ... I had to go back. Again the construction market ... I chose a primer and left. After changing clothes and preparing the compressor, I remembered ..... that I forgot about the mixer again !!!)))))

What to do? .. Do not stir the twenty-liter bucket of paint by hand! ... After thinking for a minute, I decided to do with "improvised means". In the shed I found the following pieces of thick aluminum wire:

We measure the length equal to the depth of the paint bucket, plus 10 centimeters, clamp it in a vice and bend it 90 degrees:

After that, we make another bend:

Further, grabbing with a pipe wrench (the vice is already wide))), with the help of pliers, we twist the wire into a spiral. I cut off the excess with a "grinder". (I could not photograph this process, because my hands were busy)))).

In the end, we got a great mixer and didn't have to spend money ...

From time to time, even the strongest and most independent woman who does not like to cook wants to feel like a real cook.

Inspiration for culinary feats can overtake a woman at any time, the absence of a mixer should not prevent her from accomplishing them

As a rule, such a desire is not limited to simple scrambled eggs, you certainly want something like that. For example, to make a breathtaking bizet, but, as evil, there was no mixer at hand, without which it is simply impossible to beat the protein properly. A sudden creative urge shouldn't be overwhelmed by the lack of a mixer. Self-made mixers can be for the kitchen, for children or for construction.

If there is a whisk, then an ordinary drill can save the situation.

Homemade kitchen mixer

Quite by ourselves. For this you will need:

First of all, you need to get a motor. It has to be powerful enough to handle the egg white; we won't talk about foods with a harder consistency for now. A suitable motor can be obtained from an old cassette player, for example.
Tin. Everything is simpler here, you can cut off a piece from a can of any drink.
Plastic lid from the can.
A pair of plastic cups.
You will also need a switch.
The power supply unit is selected depending on the motor power.
And of course, all this will be tinkering with a regular screwdriver.

One of the motor options

Capacity and drive

It's time to get started. We start with a glass in which you need to make a small hole. To do this, heat the metal end of the screwdriver with matches or a lighter, then make a hole with the heated tip right in the center of the bottom of the glass.

Next, we place a motor in the center of the glass and draw a marker around its edges, marking in this way where it will be located. While the engine moves to the side and manipulations with the glass continue. That is, it is clear that the mixer body is assembled first.

Now you need to cut a hole along the lines marked with a marker with a clerical knife at the bottom of the glass into which the motor will be placed. The motor should fit snugly in the hole and not fall out, so the hole should be slightly smaller than the motor.

This motor will be more than enough

Food and communication

Now you need to prepare a place for the switch and wiring. If the power supply has two wires, then one is attached to the switch, and the other to the motor. Then the switch and gearbox are connected together using a piece of copper wire.

Thus, a kind of mixer body is obtained. In order not to worry that the structure will fall apart, you can fix the motor and switch with superglue.

Screw

Let's move on to the second step. A tin is needed to make a screw. To do this, we put a thin piece cut off from the can, fold it into a ring, and wrap the resulting ring in the middle with the second piece of the same kind, so that in the end we get a figure resembling a butterfly. We got the screw, now we put a silicone nozzle on it with glue, which will be put on the pin.

While the tin is set aside until the glue is dry. We return again to the body with the motor. Place the glass with the cut side down. Here you need a second glass, in which a hole has already been made in advance with a screwdriver. It must be installed on top of the motor. The result is a design in the form of a cup on a stand. In the center of the cup is a pin, which is pre-glued to the motor, about a centimeter long.

During this time, the glue on the screw should have dried completely. We attach it to the pin. Done, now you can try. Put the necessary ingredients in a glass with a screw, cover with a plastic lid for mixing without splashes, and turn on the mixer.

Homemade doll mixer

Every child enters the age when he wants to be like an adult, necessary, responsible, to do the same as adults, girls in this period often copy the behavior of mothers, and boys - fathers. The child shows interest in household chores, including seeking to help parents in the kitchen. However, not all household appliances can be allowed to children. For example, a mixer, this is not a safe toy at all, and improper operation can lead to tragic consequences.

You can get out of this situation so that the child is satisfied and the parents are calm. Namely, build your own mixer for him. For this you will need:

Plastic tube.
Electric motor.
Any two wiring.
Batteries or portable power supply.
USB cable
Small switch.

It will not be difficult to make such a simple device, and the child will be satisfied not only with the result, but also with the assembly process itself. And an adult will also enjoy creating something with his own hands from improvised means, you can feel like the host of the program "Crazy Hands".

So, to begin with, the switch is glued with a silicone gun or superglue to the motor. Next, we take a USB cable, cut off one side of it to free the wiring, clean the rubberized base from the wiring by about two centimeters. There should be two wiring. We connect one to the motor, the other to the switch. After that, the switch and the engine are connected with a copper wire. It is better to secure the wiring with a soldering iron, but if you do not have one at hand, then you can simply tighten them properly.

Children love when something is done especially for them, he and this will appreciate more than the most expensive toy

Now the turn of the straws for drinks, we cut it into two pieces 6 centimeters long. We glue them well together along. A motor is attached to the lower part of the connected tubes. While the glue dries, grab the stirring element. To do this, you need a simple lollipop stick. A quarter of the stick must be bent in such a way that the letter "G" is obtained from the stick. With an even tip we attach the stick to the pin at the base of the mixer. Done. We connect the USB cable to a portable battery or any other power source and press the switch. Such a miniature of a mixer will perfectly cope with mixing tea or eggs, and there will be no limit to the delight of the child.

DIY construction mixer

The repair process is very laborious and sometimes you can't keep track of everything. For example, you need to mix a concrete solution, now everything is purchased and ready, when it suddenly turns out that the construction mixer is out of order or it was not at all. How to be in such a situation? Run to the store? But extra spending can not always be foreseen and there may simply not be funds for such a purchase. You can get out of the situation by making a concrete mixer yourself. For such a mixer you will need:

Drill.
Hairpin 8, 40 cm long.
Four metal plates.
Nuts and washers.

So, work begins with a hairpin. It must be turned in such a way that it is convenient to screw on the nut. On the other hand, you need to grind the pin under the triangle. This is necessary in order to properly attach it to the drill.

Next, we take on the plates. With an 8 mm drill, you need to make one more hole from the edge on each. Now you can proceed to the assembly of the mixer. A nut, washer, then platinum is installed on the length of the stud. The distance should be at least three centimeters. The top and bottom plates need to be bent like blades.

It should look something like this

The second end of the hairpin is attached to the drill, that's it, the construction mixer is ready. However, this type of home-made construction mixers will only handle small volumes of mortars.

Such a mixer will not master large volumes of work

For stirring more liquid substances, for example, paint, this option is also suitable.

For a large amount of mortar, you will need a concrete mixer, which you can also make yourself, but this will take much more time and materials, so that it will be easier to borrow from friends or use the rental services. Moreover, such a device is more useful, when completely independent, than requiring constant supervision. In this case, it is better to choose the gravitational method of mixing the solution.

An example of a concrete mixer made by yourself

The main thing to remember is that when assembling any mixer, you must observe safety precautions, and if you are not confident in your abilities, then it is better not to undertake such painstaking work, but to go to the store and buy a decent product.

When carrying out various construction and repair work, it is very often necessary to mix several components to obtain a homogeneous mixture composition, whether it be various varnishes, paints, putties or sand-cement mortars. Making a quality mixture by hand is difficult. To carry out such work, a construction mixer will become an indispensable assistant - a special device that will significantly reduce labor costs, save time and get a high-quality mixture.

Classification by design

Structurally, all mixing devices consist of a drive and a nozzle. The drive housing contains an electric motor, a gearbox, a nozzle attachment system and controls (switch, speed switch). Nozzles are special devices that are fixed on the drive and with the help of which the components of the mixture are mixed. According to their purpose and scope, modern construction mixers are divided into two classes:

Drill mixers are dual-use devices. They are equipped with a cam chuck, which allows you to securely fix in it both nozzles for mixing mortar (with a corresponding shank diameter), and drills for arranging holes of large diameter. Such a tool belongs to low-speed drills, therefore, it cannot functionally replace a conventional electric drill. However, low rotational speed and high torque make it possible with their help not only to mix a wide variety of solutions (up to heavy cement or sand and gravel), but also to use them for drilling large holes even in very hard materials.

Construction electric mixers are highly specialized tools that are designed only for mixing various mixtures. The range of these devices is very diverse, you can even choose a construction mixer that will successfully replace a household concrete mixer (and, not inferior to it in performance, but significantly surpassing it in ease of transportation and a variety of functionality). These devices are single-spindle (they provide for the installation of only one nozzle) and two-spindle (they install two nozzles at once, which rotate in opposite directions).

Of course, when using any construction mixer, you will need an appropriate container for mixing the components.

Varieties of mixers depending on power

Depending on the power, which is the main technical characteristic that determines the scope, construction mixers (both highly specialized and drill-mixers) can be divided into three main groups:

Advice! When we choose a construction hand mixer, it is necessary to consider not only its power, but also its weight. The more powerful the device, the heavier it is, which means that it will be more difficult to work with it.

Varieties of attachment attachment systems

Construction mixers from various manufacturers are equipped with different attachment fixing devices:

Jaw chuck, in which the shank is fixed using a special crimp wrench (like a conventional electric drill).
Cam chuck of the QuickFix system (like a household screwdriver - crimping is carried out without the use of a special tool).
Threaded connection of the shank to the mixer M12, M14 (much less often M21), using a conventional wrench, which is included in the electric mixer kit.
SDS-plus and SDS-max chucks (the design is similar to the mounting of drills in household rock drills).
HEX chucks (8, 10 or 12), for quick change and fixation of attachments with a hex shank with a spring-retaining groove according to ISO 1173 E3.

Construction mixer attachments: shapes and sizes

An attachment for an electric construction mixer is a rod with a whisk at one end for mixing and a shank at the other for attaching the attachment to the drive. After you have decided on the composition of the mixture to be mixed, you can choose the shape of the whisk. And the standard of the bit shank must match your power tool.

Types of shanks for mixer nozzles

Now on sale there are a large number of mixer attachments with shanks of various shapes:

Regular hexagon, 8, 9 or 10 mm. Such attachments are intended for use with power tools having a conventional jaw chuck.
Hexagon socket (8, 10 or 12 mm) with groove for spring fixing in HEX chucks (can also be used in power tools with conventional chuck).
Thread M12, M14 and 21X1.5. Attachments with such shanks can only be used in highly specialized mixers.
Shanks designed to fit in SDS-plus chucks (can also be used in a simple rock drill).

Sizes and shapes of whisk nozzles for mixer

Mixing attachments are produced:

Standard lengths 400 and 600 mm (for some extensions 400 mm are provided - total length up to 1 m).
The diameter of the whisk (part intended for stirring) is from 80 to 220 mm.

The shape of the whisk is chosen depending on the mixture to be mixed. The main forms of corollas:

Spiral. Such corollas are subdivided into right-handed, in which the spiral is twisted clockwise, and left-handed, in which the spiral is twisted counterclockwise. Right-side beaters in the process of mixing raise the solution from the bottom up and are intended for heavy or thick mixtures (concrete, sand and gravel, bituminous). Left-handed spirals, on the contrary, grab the mixture from above while stirring and lower it down. They are intended for mixing various paints and varnishes, various flowable mixtures and liquid fillers, since they do not splash when using them.

On a note! If the construction mixer is equipped with a reverse system that rotates the whisk both clockwise and counterclockwise, then only one nozzle (right-handed or left-handed) can be used for different mix compositions.

Corollas with straight blades. Stirring takes place only in the horizontal plane, which prevents the entrapment of air and its entry into the mixture. Suitable for mixing various gypsum-based compositions (air ingress is highly undesirable), mixtures for self-leveling floors and the like.

Screw-shaped beaters (the screw is usually made of plastic). Mainly used for light liquid mixtures. Sometimes two screws are installed on the axle: the lower one, which lifts the components up, and the upper one, which prevents the mixture from splashing.

Important! In the technical description, manufacturers indicate which type of mixture a particular whisk is intended for mixing, as well as the maximum recommended amount of solution for which it is designed.

Depending on the size, materials and purpose, the price for these accessories is in the range of 100 ÷ 1100 rubles.

Homemade mixer

Making an electric mixer with your own hands is quite simple. For this, an ordinary household electric drill or hammer drill can be used as a drive. For a drill, attachments with a hex shank or HEX are suitable. Both are conveniently fixed in the chuck of the drill. The main thing is that the size of the hexagon (standard: 8, 10 and 12 mm) corresponds to the maximum size that can be inserted into the drill chuck.

Attention! For mixing solutions, only low-speed drills or devices with speed control can be used.

If you use a hammer drill as a drive (naturally, in a non-impact mode), then you need to buy bits with a shank designed for mounting in an SDS-plus chuck.

However, it should be noted that motors and gearboxes, both for electric drills and for rock drills (even powerful ones), are designed only for longitudinal load. Therefore, a homemade mixer based on them is quite suitable for mixing light solutions and in small volumes. When stirring solutions, the drive experiences significant radial and horizontal loads, which can lead to overheating and failure of the electric motor. Therefore, it is better not to do a concrete mixer with your own hands from a drill or perforator. Although their use is quite acceptable when mixing paints, thin fillers and other light solutions.

In custody

When choosing a device for mixing mixtures, it is necessary to be guided by their composition and volume. Based on this, you can choose a construction mixer of sufficient power so as not to overpay for a too advanced unit. If you need a mini mixer for mixing concrete, then it is better to purchase a powerful semi-professional tool from a trusted manufacturer.

A drill mixer is a great helper for any builder. Such devices have a rather powerful motor and two ergonomic handles, which are necessary in order to hold the tool while mixing mortars and mixtures. This is a convenient mechanism that combines several important functions at once.

Purpose

The construction sector of the industry does not stand still - every year new compounds appear that are used for the construction of structures, minor and major repairs. Both glue and plaster and many other materials go on sale in the form of a powder, which must be diluted with water in order to make a full-fledged composition out of it.

In order for the components of the mixture to mix as well as possible and to form a homogeneous working mass, it is necessary to choose the right tool. For example, if you can mix wallpaper glue with an ordinary stick, then which method will be ineffective for cement mortars and putties, especially if you need a solution in large volumes.

Mixing building mixtures with improvised means, as a rule, does not give the required quality of the working composition: many lumps form in it and a large percentage of dry matter remains, which could not get wet properly.

Many users in such situations resort to a hammer drill., which has the necessary rotation capability; however, experts do not recommend using this method, since the hammer drill is initially oriented to loads in a different plane without any influence of radial forces. Of course, it is possible to mix a small volume of the solution with its help, but in large quantities you risk simply disabling your instrument, which, by the way, is quite expensive.

An excellent solution in this situation can be the purchase of a drill mixer, which is optimal for mixing compositions in a volume of up to 15 liters in one go.

Such devices are optimal both in everyday life and during professional repairs. Unlike the hammer drill and the usual drill, they have a stronger bearing, in addition, the mechanism is equipped with a powerful gearbox, which is protected by a particularly durable metal case. Thanks to this configuration the device can work even at the lowest rpm.

An important plus is the fact that such construction mixer can simultaneously perform the function of surface drilling, that is, in fact, it is a 2-in-1 device.

Types of structures and their characteristics

The drill mixer is used for large-scale repair work; the user usually holds it in his hands when mixing the solution, because the device has ergonomic handles that make the operation of the tool less laborious. If the motor of the device has a power of more than 1 kW, then a special gearbox is built into it: it is suitable for use not only at the very first speed, but also when changing from the first to the second.

The first is used for the preparation of thick dense mixtures, for example, mastic, and the second - for gypsum and cement. Stirring of paints and varnishes and other liquid substances with a minimum torque is also permissible at the second speed.

In order to make the work more comfortable, it is better to use tools that are supplemented with a speed stabilizer or starting current limiters.

Such drills, as a rule, have different configurations. Usually they come with several types of nozzles, which can have several shapes.

Right-hand spiral mixing nozzle - used for such solutions that have a very viscous structure. These include cement, concrete, as well as various kinds of plasters and glue. Such a nozzle mixes the solution, as if pushing it upwards, mixes the composition at the top, and then drops back.
Left-hand spiral nozzle optimal for mixing paints and varnishes. Here the principle of operation is reversed: the mixture is pushed from top to bottom, where it is stirred and rises back.
Screw nozzles allow mixing light compositions.
Crosspiece- a more specialized nozzle, it is used in cases where it is very important to prevent air from entering the container with the mixture.

Advantages and disadvantages

The main advantage of the drill mixer is its multifunctional use. On the one hand, the tool is classified as a drill, therefore, in addition to mixing mortars, it can be used to form holes in surfaces of various types, even the hardest and most dense ones. On the other hand, a drill of this type belongs to the category of low-speed ones, therefore it cannot replace a drill by 100%, but at the same time, it is precisely low speeds that make it possible to mix even the most dense compositions.

Obviously, such a structure cannot be used in industrial volumes, its capacity and design features will not be enough to cope with an intensive operation mode. But with the solution of small everyday tasks for minor repairs and decoration of an apartment or a private house, she will cope in full.

Such a drill weighs much more than an ordinary one: its weight is more than 3 kg, therefore, frequent drilling with such a unit is associated with significant physical efforts.

Principle of operation and features of use

Depending on the principle of operation, there are three types of tools:

drill mixer;
drill mixer with one whisk;
device with two rims.

A conventional electric drill mixer is a low-speed, impact-free type. The power of this tool ranges from 500 to 2000 W, there are 2 comfortable handles, a fairly large cartridge with a diameter of up to 16 mm.

Two-handed models are divided into options with a single whisk or with two, the difference follows from the name: mechanisms with two whisks mix even the most viscous mixture, they are equipped with a rather powerful gearbox and can easily cope with solutions of various consistencies - from light to concrete.

Model rating

Drill mixers of the following brands are the most popular among consumers.

FiolentIs a Russian-made product that is optimal for mixing the thickest and most viscous compositions. The power of the device is 1100 W, and the speed is 600 rpm.
Rebir- the most popular low-speed drills are produced under this brand. Selected models from this manufacturer have exceptional performance characteristics: power up to 2000 W and rotation speed up to 500 rpm.

Interskol- offers a wide range of drills-mixers, the power of which reaches 1050 W. Such a tool is optimal for mixing any building mixtures, even concrete, and also for drilling: for example, if you put a special drill for wood in it, you can get a hole up to 1 m long in a matter of seconds.
ZUBRIs one of the most demanded brands on the domestic market. The models represented in the range of this manufacturer have exceptional power parameters - up to 1200 W - and rotation speed (up to 850 rpm).
MakitaIs a well-known Japanese brand that is in demand all over the world for its quality and reliability. It is noteworthy that all models of this brand, in addition to excellent technical characteristics, are also distinguished by practicality, because they consume much less energy than competitors.

How to choose?

product weight - in the range of 2.7-4.5 kg;
power - 620-110 W;
rotation speed - up to 1050 rpm;
torque - 70 N / m.

In addition, when choosing a suitable model, pay attention to additional functions that may be useful to you: smooth start, automatic turn-on mode, additional housing insulation, overheating protection and others.

How to do it yourself?

If you wish, you can make a construction mixer yourself. For this, you need to use the most common drill as a drive, and any product with a hex shank is suitable as a nozzle. Such a device is quite easily fixed in the drill chuck, the main thing is that the dimensions of this hexagon correspond to the minimum chamber size that can be placed in the chuck.

However, keep in mind that the motors and gearbox of a standard mixer are designed exclusively for a longitudinal surface, therefore, using such a homemade tool, only very small portions of the mortar can be mixed.

In the next video, you will find the basic features of drill mixers.
