The top of the rotating shaft is fixedly installed with a motor, and the upper end of the rotating shaft is fixedly installed with a large rotor. By setting a large rotor, a small rotor, a filter screen plate, etc., the purpose of high efficiency and good use effect is achieved. The materials are processed in batches and steps, which can avoid the accumulation of materials and affect the operation of the rotor. Different rotor sizes have different crushing capabilities, and different treatments can improve the working efficiency.

[0027] The filtering mechanism 2 is arranged on the cylinder body 1. The filtering mechanism 2 includes a filter plate 21, a limiting rod 22 and a filter net 23. A filter plate 21 is arranged inside the cylinder body 1, and the filter plate 21 is in fit with the inner wall of the cylinder body 1. Two groups of limiting rods 22 are fixedly installed on the inner wall of the cylinder body 1, and the filter plate 21 is movably sleeved on the two groups of limiting rods 22. A filter net 23 is fixedly installed on the inner wall of the filter plate 21.

[0028] The filtering mechanism 2 further includes a rotating rod 24, a cam 25 and a first motor 26. The rotating rod 24 is rotatably installed between the inner walls of the cylinder body 1. The cam 25 is fixedly installed on the outer surface of the rotating rod 24. The filter plate 21 is mounted on the cam 25. The first motor 26 is fixedly installed on the outer surface of the cylinder body 1. The rotating shaft of the first motor 26 is in transmission connection with the rotating rod 24. Through the filtering mechanism 2, after the first rotor 34 crushes the powder material, the powder material that is not fully crushed can be filtered, and the effect of jitter is generated during its operation, which can not only bounce up the powder material that is not fully crushed, make it contact with the first rotor 34 and be further crushed, but also shake off the powder material stuck in the filter net 23 and make it fall normally, solving the problem that in some existing powder separators, when filtering through the filter net, the powder particles are small and easy to block in the filter net holes due to the accumulation of friction force, affecting the normal falling of the material, and improving the practicability of the powder separator.

[0029] The crushing mechanism 3 includes a U-shaped plate 31, a second motor 32, a rotating shaft 33, a first rotor 34 and a second rotor 35. The U-shaped plate 31 is fixedly installed on the top of the cylinder body 1. The second motor 32 is fixedly installed on the top of the U-shaped plate 31. The rotating shaft 33 is rotatably installed on the inner top of the U-shaped plate 31. The rotating shaft of the second motor 32 is in transmission connection with the rotating shaft 33. An installation hole is opened on the top of the cylinder body 1. The rotating shaft 33 extends into the cylinder body 1 through the installation hole.

[0030] Working principle: Open the cylinder cover 5, pour in the powder material, cover the cylinder cover 5, control the second motor 32 to start, drive the rotating shaft 33 to rotate, the rotating shaft 33 drives the first rotor 34 and the second rotor 35 to rotate. The powder material entering the cylinder body 1 will first fall on the filter net 23 of the filter plate 21. Control the first motor 26 to start and drive the rotating rod 24 to rotate. The rotating rod 24 drives the cam 25 to rotate. The cam 25 continuously collides with the filter plate 21 to make it shake up and down. The material with smaller particles on the filter net 23 will directly pass through the filter net 23 and fall, and be further crushed by the second rotor 35. While the powder material with larger particles will remain on the filter net 23. The shaking filter net 23 will continuously bounce up the powder material and make it fully contact with the first rotor 34 until the powder material is fully crushed. After completion, open the discharge cover 6 to collect the fine powder formed after full crushing, and then open the door panel 8 to clean the coarse residue that cannot be crushed on the filter net 23.

However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
