When the device is in use, the user starts the motor, and the motor rotates to drive the threaded rod to rotate, and the threaded rod rotates to drive the nut to move, and the nut moves to drive the connecting frame to move, and the connecting frame moves to drive the unloading plate to move the material on the surface of the sieve plate to the discharge port for unloading. By setting the unloading device, the material inside the sieve plate is effectively unloaded, which plays a role in quickly unloading the material, reducing the problem that when the device is in use, the screened material is easily accumulated on the surface of the sieve plate and difficult to unload when the device is graded and screened. The situation that the material on the surface of the sieve plate is accumulated and difficult to screen occurs, and the unloading device can move the material accumulated on the surface of the sieve plate to the discharge port, which is convenient for material unloading and improves the efficiency of the device.

[0015] In the utility model, an auxiliary component is provided. Before the device is used, the user connects the connecting block with the inside of the connecting groove, and the connecting block moves to push the card plate to move. When the card plate moves, it drives the spring to displace and deform to generate elastic force. After the connecting block is completely connected with the inside of the connecting groove, the spring loses its restraint, drives the card plate to limit the connecting block, and then when the device is running, it drives the cleaning brush to clean the surface of the sieve plate. By providing the auxiliary component, the surface of the sieve plate is effectively cleaned, and the material blocked inside the sieve plate is cleaned, which reduces the problem that when the device is in use, the material on the surface of the sieve plate is easily pushed against the inside of the sieve plate when the feed plate moves, causing the sieve plate mesh to be blocked, making it difficult to screen the material. The auxiliary component can clean the material blocked inside the sieve plate, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
