Rotary sieve for DIY soil.
Hello.
Due to backyard earthworks and a large amount of stone in the ground, there was a need to build a screen. YouTube videos were the inspiration.
The frame is made of angle bar 40. The proper screen is made of welded mesh (1x2m) with 12x12mm mesh made of 1mm wire. The net has been attached to the bicycle rims (62cm inside). The shaft is a 3/4 inch pipe mounted on 2 bearings, '' spokes '' made of 6mm wire. Engine from an old concrete mixer with a capacity of about 500W 1420rpm.
The screen turns at a speed of about 50 rev / min. At faster revolutions, the centripetal force is too high and the earth sticks to the grid.
The whole may not look great but meets 100% design assumptions. The cost of construction due to the possession of some elements did not exceed PLN 200.

Cool, simple design :D . That I would make some "hopper" to pour "material" from the front :idea: and covers for these gears, because "he doesn't sleep badly". [Read more]
Replace the engine fan housing. [Read more]
I thought about it too but due to material shortages I abandoned the idea. After a few tons of shifted soil I can safely say that it is better without a hopper. Maybe it would look nice but the shovel... [Read more]
And how will the shoulder blade break off and hit someone? And this may not be difficult. [Read more]
Why such a large distance from the front of the frame to the drum? You can see that because of this the axle bends when throwing soil. A cover from above would be useful, because a lot of soil flies... [Read more]
The aforementioned funnel (chute) was supposed to be there. But as I wrote earlier: I would have to lift each chute with soil about 30cm higher and this is really a lot when loading manually. Secondly,... [Read more]
I have a question - did you try to screen the aggregate there? Would the construction stand to screen such material? I mean personal conviction - because I am thinking of such a design with the difference... [Read more]
@beretus Personally, aggregate was not sifted because I did not have such assumptions during the construction. I think that the sieve can handle it provided you make a funnel with a regulating slide.... [Read more]
And as the mesh was attached to the wheel because for welding it is probably too thin [Read more]
Ordinary wire for reinforcements. [Read more]
A little expensive piece of sheet metal just around the fan will improve cooling. On the front you can put a piece of mesh even of plastic. And what kind of colleague does anarchism write? This... [Read more]
It took me a while but finally I assembled my drum screen. The assumptions were similar except that I did not want to have an axis throughout the entire length of the drum. Short description: The motor... [Read more]
What is a net? Where do you buy one? [Read more]
In my humble opinion, there should be a hopper and, in addition, a rim - a bank a few centimetres high to prevent the backfilled soil from escaping from the drum. The hopper has the advantage that the... [Read more]
