A synchronous belt 11 is sleeved on the outer wall of the synchronous wheels 10. Through the synchronous wheels 10 and the synchronous belt 11, the rotation of the connecting rod 8 can drive the rotation of the rotating rod 6. A clamping component is provided at the upper end of the protective plate 3 to fix the protective plate 3 on the surface of the feeding hopper 2;

[0022] Specifically, referring to Figure 5 , the clamping component includes a sliding rod 14, a sliding sleeve 15, a clamping block 16, an electric telescopic rod 17 and a pull rod 18. The upper end of the protective plate 3 is fixedly connected to the sliding rod 14. The rod body of the sliding rod 14 is slidably connected to two sliding sleeves 15. The outer wall of the sliding sleeve 15 is fixedly connected to the clamping block 16. The upper surface of the protective plate 3 is fixedly connected to the electric telescopic rod 17. One side of the electric telescopic rod 17 is hinged to two pull rods 18. The other end of the pull rod 18 is hinged to the sliding sleeve 15. A clamping groove is provided on one side of the feeding hopper 2 and the protective plate 3.
