[0014] Beneficial effects of the present invention: 1. The first driving motor drives the rotating wheel to rotate through the transmission action of the transmission box.

When the synchronous wheel and the flat pulley operate synchronously, the filter bin and the spiral conveying blades can be driven to rotate. The spiral conveying blades in the filter bin help to transfer the material to the discharge port. The material is filtered through the filter screen in the filter bin and finally discharged from the discharge port. Through synergistic effect, the various components in the drive mechanism can efficiently complete the material processing task, improve production efficiency and ensure the quality of the material.

The function of the sealing gasket is to ensure the sealing of the filter bin and prevent material leakage. The stabilizer bar plays a role of fixing and stabilizing to ensure the stability of the system during operation. The matching design between the stabilizer groove and the stabilizer bar can increase the stability and accuracy of the spiral conveying blade during operation and prevent it from deviating from the track or swinging. Such a design can improve the reliability and operation efficiency of the system and ensure the smooth transmission and filtration of materials during the processing process.

[0017] The device constrains the movement of the roller through the limit groove, ensuring the stability and safety of the equipment during movement, while the design of the dispersion rod and gasket helps to disperse and evenly distribute the material, improving the processing efficiency and quality. Through the synergistic action of the third and fourth drive motors, the synchronous operation of the filter bin and the spiral conveying blades is achieved, thereby improving the efficiency and quality of material processing and ensuring smooth transmission and filtration of materials.
