Through the threaded connection between the lead screw 704 and the threaded block 702, stable lifting of the lifting component 7 is realized, and the structure has self-locking property, that is, even if power is cut off or external force acts, the current position can be maintained, and accidental lowering is prevented; by controlling the rotation direction and speed of the first motor 706, the lifting direction and speed of the lifting component 7 can be accurately controlled, and the control mode is simple, reliable and easy to realize automatic control.

[0033] The rotating assembly 4 comprises a first spur gear 401 and a second spur gear 402, the first spur gear 401 and the second spur gear 402 are both rotatably installed at the top of the feeding hopper 2, the first spur gear 401 is in meshing connection with the second spur gear 402, the third mounting piece 703 and the first motor 706 are fixedly installed at the top of the first spur gear 401, the top of the feeding hopper 2 is fixedly installed with a second motor 403, and an output end of the second motor 403 is fixedly connected with the second spur gear 402.
