How to make a sand sifter with your own hands. Drainage and screening of the earth

A sieve for household and construction needs, you can easily do it yourself. As an example, a garden sieve, through which it is convenient to sift the compost. And not only compost, it is useful for sifting earth or sand.

The dimensions of the parts depend on how you plan to use the mesh. For sifting a large amount of sand or soil, it is better to make the frame larger, for example 700/1200 mm. . This option is lighter and more portable.

For the manufacture of a wooden frame, bars with a section of 50/50 mm are suitable. .
The type of wood is not so important, although I would choose birch or beech.

You will also need a metal mesh with a cell of 6-12 mm. , screws, nails or staples.

The frame in the photo is 550/550 mm. , for manual sieving is quite suitable.
We cut the ends of the bars at an angle of 45 *, the length of the parts at the outer corners, respectively, will be 550 mm. .

We collect the bars in the form of a frame for a picture and tighten them with self-tapping screws from the outside.
Just be sure to pre-drill holes, at least half the length of the self-tapping screw, so that the ends of the parts do not burst when tightened.
To make the frame stronger, it is better to screw in two self-tapping screws on each side of the corner, that is, four for each corner. In total, you will need 16 self-tapping screws 75-85 mm long. .

We put the finished frame on a metal mesh, mark it and cut it.
You can cut with pliers, but it takes longer. Faster and easier to use grinder.
The grid should not go beyond the dimensions of the frame, it is better to make it a little smaller.

We impose a grid on the underside of the sieve and nail or staple it.
To prevent the mesh from sagging, it is better to hammer in the staples with an interval of at least 50 mm. . To give do it yourself.

After retiring, my wife and I moved to the countryside and took up household chores with great enthusiasm.

A small "roar" for sifting sand (photo 1)

Its design is simple. On a frame that can be welded from a corner (I used a randomly found frame), I installed an electric motor from an old Riga type washing machine, on the axis of which I installed a cam (photo 2). I made it from the rocker of the pusher mechanism from Zaporozhets - the diameter of its hole coincided with the diameter of the engine shaft. A metal plate is fixed on the frame in the plane of rotation of the cam.

I fixed a wooden frame with a mesh on one side on the axis, and closer to the engine through threaded studs (photo 3). The lowermost position of the frame is adjusted using a nut on a stud on the opposite side of the spring and is fixed with a lock nut. The springs keep the frame pressed against the cam.

Setting up the mechanism is extremely simple. With the help of nuts on the studs, you need to set the preload for the cam in such a way that, when it hits the tangent, the frame “throws up” and the engine does not stop.

Before sifting sand, you need to raise the frame, start the engine (let it spin up) and you can work. Depending on the moisture content of the sand, it must be stirred. To obtain sand of a finer fraction, I insert a grid with cells of the desired size into the frame. And do not forget about the headphones: the design lives up to its name.

Tool for sharpening knives on a woodworking machine

It implements the flat grinding method. The design is clear from photos 1 and 2. The base is made from a corner. On the inside, a rotary plate is mounted on the axis, to which, in turn, an AB-42 engine with a power of 40 WT, 2700 rpm is attached. The abrasive circle is closed by a casing from the grinder.

The device is installed with an abrasive on the knives in such a way that the planes of the back face of the knife and the abrasive coincide. I control the correctness of the installation "in the light". After that, you need to fix the drum (photo 3) and sharpen the knives by slowly moving the device.

In principle, a micrometer screw is not needed (the first option was without it), but with its help it is very convenient to set the amount of removal. It can be replaced with a screw with a fine thread pitch (0.5-1.0 mm). I edit the abrasive with a diamond from an old glass cutter fixed to the machine table (photo 4). I finish the blades (deburring) with an abrasive bar.

After sharpening, it is necessary to correct the installation of knives. It is convenient to do this with the help of a dial indicator, on the probe of which a metal plate is fixed, and a strip of textolite is glued on it (photo 5).

The base of the fixture is made of 25×25 pipe and filled with lead. The indicator on the table must be set to zero, then move the probe to the knives. Turning the drum, find the extreme position of the indicator arrow (with further rotation of the drum, the arrow will move in the opposite direction) and set the knives to the zero indicator mark.

Drainage Benefits

1. Drainage removes water harmful to plants, lowers the level of groundwater.
2. Drainage improves soil fertility.
3. Drained soil is more accessible for spring work.
4. Drainage increases the growing season.
5. Drained soil is easier to work - cheaper.
6. Drained soils respond better to mineral fertilizers.

How to sift the earth

When arranging flowerbeds, the earth should not be sifted: when the sifted earth subsequently settles, it is so compacted that the access of air to the roots of plants is too difficult and the plants slow down their development or completely stop growing. However, it is sometimes necessary to sift soil containing too many stones, rubble, wood chips, etc. A wooden frame is arranged about 2.5 arshins in height and 1.5 in width; the bottom of this frame is boarded up to a height of 1 arshin, while the rest of the frame is covered with wire mesh, the cells of which should be at least 1/4-1 inch squared.

A finer mesh is unsuitable for sifting the earth. This grid is installed at an angle of 50 ° and fixed motionless. Close to the net, from its outer side, a wheelbarrow is attached; the sides of the wheelbarrow are beveled so that it can be moved close to the part of the frame boarded up with boards. A worker with a shovel throws the sieved earth onto the grid, and the smaller parts are poured through the grid, and stones, roots, etc. remain on the outside of the net and fall into the wheelbarrow. Thus, the screenings do not have to be piled a second time into the wheelbarrow: they immediately fall into it and can be immediately taken away.

Drainage device in flower pots

Seedings of the earth, with the exception of large stones and chips, should not be thrown away: they provide excellent drainage in flower pots for planting. Usually, the lower layers of the earth in a pot, under the influence of constant watering, quickly become compacted, almost do not let water through, and the plants suffer from a clod that does not dry out. A completely different result is obtained with a rational drainage device: the drain hole expands somewhat and is laid with a shard; a layer of cuttings is poured onto the shard, the thickness of which depends on the diameter of the pot, i.e. the larger the pot, the thicker the layer of seedlings. Earth is already poured on these seedings and a plant is planted.

Water during irrigation, having saturated the upper layers, tends downward and, of course, quickly flows through the layer of seedings. In the course of time, particles of earth are carried away with the water and fill the gaps between the sowings, and the water is somewhat delayed, but this does not happen until a new transplant is needed, and therefore the matter can again be corrected in the same way.

I have long wanted to buy a sieve for sifting flour, but somehow it didn’t work out or I forgot. And so, when it was needed again, I decided, why not make a sieve with my own hands. Not such a complicated thing, although very necessary in the economy. Often in the kitchen, and not only, there is a need to sift or separate something. For example, when doing bread kvass , tasty triangles or worked with old paint.

In the last example, a disposable funnel with a sieve is generally needed, so after analyzing all the options, I thought that it would be more correct to come up with and be able to make a sieve with my own hands. Only then will it be possible to take into account all the nuances of the application.

How to make a sieve with your own hands

The most affordable material for making a sieve or strainer with your own hands is plastic buckets in which mayonnaise, gauze or for mosquitoes are sold. Containers from under mayonnaise have a wonderful shape that allows you to insert empty containers one into another. This property of the form will be used in homemade.

To make a sieve with your own hands for sifting flour or something else, you need two plastic buckets.

At one we cut off only the bottom.

The second has both a bottom and an upper rim.

We leave the middle part for the sieve with our own hands.

The photo below showed unused cutouts from plastic buckets.

And a general, explaining photo of what you need to do with your own hands.

The size of the cells of the grid used should be different depending on the sieved substances. For example, for sifting flour is very small.

Here's what I have

We assemble the sieve with our own hands from prepared blanks as shown in the photographs.

And here is a sieve made by hand. The mesh is well stretched and clamped between the workpieces.

I left the lid on purpose, it is more convenient to sift flour with it.

How I made a sieve with my own hands, I immediately tested it by sifting flour for the recipe unusual pancakes. Homemade It turned out very convenient, the sieve is deep and collapsible.

Do-it-yourself sieve for kvass and liquids

Developing the theme, I remembered how I suffered, filtering bread kvass.

Here, in order to drain kvass from a jar, you need a large sieve, so I suggest an option from a plastic 5-liter bottle. This is a quick, collapsible sieve combined with a container. In the manufacture, we again use the same property of the forms.

We take a bottle and cut out the rim only in the first sector.

How to mark sectors? Very simple! The ring cut along the first sector should fit snugly into the bottom of the bottle.

From above, on the resulting container, put gauze and clamp it with a cut-out rim.

Now you can safely strain the kvass through a sieve and leave it filtered for complete drainage of the liquid.

Also, as an example, a quick strainer for liquid from a glass, a bandage and a plastic bottle.

I hope it's clear without explanation. Again we got a sieve with our own hands.

In the same way, you can make a funnel with a grid with your own hands.

A funnel with a mesh can be made collapsible, then it will be possible to change the gauze and mesh. Or not collapsible, from above, in a circle, we pass with a stapler.

Well, I hope these options on how to make a sieve with your own hands are enough to cover the solutions to most tasks at home for sifting, screening and filtering.
