[0002] Hoppers are commonly used material storage devices. In the production process, hoppers serve to store and transport materials to maintain the continuity of production and allow materials to be temporarily stored to buffer impacts as needed during the production flow.

[0003] In practical use, anti-jamming hoppers mostly adjust the size of the hopper channel by the deformation between springs to avoid material blockage. However, when the channel is expanded to its limit, there is still a possibility of blockage. Therefore, the existing technology needs to be improved. Utility Model Content

[0011] Furthermore, support rods are installed on both outer walls of the hopper, and motor fixing sleeves are installed at the ends of the two support rods, with the motor installed inside the motor fixing sleeves.

[0012] Furthermore, the side wall of the L-shaped clamping plate is provided with clamping screw holes, and a clamping screw is screwed into the inside of the clamping screw holes. One end of the clamping screw is connected to the clamping plate, and the other end of the clamping screw is equipped with a turntable.
