By setting the distance between the two sides of the screen 11 and the inner cavity of the frame 3 to be greater than the surface sliding distance of the sleeve 13 on the slide bar 14, the screen 11 is prevented from colliding with the frame 3 when it swings back and forth. The inclination angle of the screen 11 is thirty degrees. The left side of the screen 11 is fixedly connected with a baffle. By setting the inclination angle of the screen 11 to be thirty degrees, the left side of the screen 11 is fixedly connected with a baffle, which facilitates the sliding of materials and also prevents the crushed materials from falling from the screen 11.

[0028] Working principle: start the motor 4, and the motor 4 drives the cam 5 to rotate. The rotation of the cam 5 drives the pulley 9 connected to the sliding surface to rotate, and uses its own convex point design to drive the concave frame 8 to move. The movement of the concave frame 8 drives the connecting rod 7 to slide on the inner surface of the slide cylinder 6, and then drives the connected screen 11 to move.
