The rotation of the output shaft drives the crushing wheel to rotate. The crushing wheel rotates to crush the raw materials. At the same time, the rotation of the output shaft drives the rotating plate to rotate. The rotating plate rotates and contacts the inclined plate. The rotating plate continues to rotate to move the inclined plate. The movement of the inclined plate drives the installation plate to move. The movement of the installation plate drives the brush to move. The movement of the brush cleans the raw material debris on the surface of the crushing wheel to prevent the crushed raw materials from sticking to the surface of the crushing wheel, which will reduce the processing efficiency of the raw materials. The rotating plate continues to rotate without contacting the inclined plate, so that the installation plate is reset by the elastic force of the No. 1 spring. The reset of the installation plate drives the reset of the inclined plate and the brush. The crushing wheel is cleaned by the reciprocating motion of the brush.

[0014] (2) In the invention, the output shaft rotates to move the moving block, and the movement of the moving block drives the L-shaped rod to move, and the movement of the L-shaped rod drives the baffle to move, and the movement of the baffle allows the raw materials to enter the interior of the main body and fall into the crushing box. At the same time, the movement of the baffle drives the rack to move, and the movement of the baffle allows the raw materials to enter the interior of the main body, thereby realizing intermittent feeding and avoiding excessive one-time feeding that leads to reduced work efficiency. The rack moves and contacts the gear, and the rack continues to move to drive the gear to rotate. The rotation of the gear drives the rotation of the shaft, and the rotation of the shaft drives the long plate to rotate. The rotation of the long plate throws the raw materials toward the triangular block, and the larger raw materials are impacted and crushed, thereby performing preliminary processing on the raw materials.

[0015] (3) In the present invention, the moving block contacts the moving frame, and the moving block continues to move, driving the moving frame to move. The movement of the moving frame drives the connecting rod to move. The movement of the connecting rod drives the frame to rotate. The rotation of the frame drives the screen to rotate. The screen rotates to screen the raw materials on the screen, thereby improving the screening efficiency. At the same time, the bent rod contacts the protrusion, and the frame continues to rotate so that the bent rod bends and then hits the protrusion. The vibration generated by the bent rod hitting the protrusion improves the screening efficiency of the raw materials. The raw materials that have not passed the screening fall on the discharge plate. At the same time, when the frame rotates and contacts the discharge plate, the frame continues to rotate, driving the discharge plate to rotate, and the unqualified products are discharged through the swinging force.
