[0006] Preferably, a storage cavity is opened on the inner wall of the square tube, and a guide plate is bolted to the inner wall of the square tube located in the storage cavity. The square tube is provided, and the level of the equipment hopper can be increased through the square tube, thereby reducing the problem of the hopper directly guiding the material into the screening drum, causing damage to the material surface.
[0007] Preferably, the square tube is connected to the inner wall of the screening drum, the lower cover plate is in contact with the inner wall of the square tube, and the front sponge pad is in contact with the inner wall of the square tube.

[0008] Preferably, the guide plate is located on the inner wall of the screening drum. The guide plate is provided so that the material falling into the screening drum can be guided by the guide plate, thereby reducing the collision between the material and the screening drum.
[0009] Preferably, the inner wall of the mask is provided with an extension component, and the extension component includes a connecting plate. The inner wall of the mask is provided with a circular hole, and the connecting plate is rotatably connected to the inner wall of the circular hole.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] In the utility model, by setting auxiliary components and extension components, when grading the ore, the material is poured into the screening drum through the auxiliary components and the extension components, and then the screening drum is rotated under the drive of the servo motor, and the material is pushed to move during the rotation.

When the positioning bolt moves to the maximum spacing, the positioning bolt is rotated clockwise. The positioning bolt and the threaded sleeve are engaged. The sleeve engages and screws into another socket. When the positioning bolt is tightened again, the threaded sleeve can be used to limit the position of the L-shaped side baffle. At the same time, the position of the connecting plate is limited by the L-shaped side baffle. Then the extension component is unfolded and the feed port is adjusted. Then when dumping the material, the material falls from the storage box onto the rear sponge pad. The rear sponge pad absorbs the impact force generated when the material falls. At the same time, the material rolls onto the front sponge pad under the guidance of the rear sponge pad. The front sponge pad guides the material and guides the material into the square tube. When the material enters the square tube, it will roll onto the guide plate under the action of its own falling inertia. Then, under the guidance of the guide plate, the material will lightly fall into the screening drum. By setting auxiliary components and extension components, the equipment can buffer and protect the added material, thereby reducing the problem of poor applicability of the equipment, facilitating adjustment of the discharge specifications of the equipment, and improving the ease of use of the equipment.
