The upper end of the threaded sleeve 14 is hingedly connected with a connecting rod 15, and the other end of the connecting rod 15 is hingedly connected to the rotating rod 10. The other end of the connecting rod 15 is connected to the upper end of the rotating rod 10, so that the rotating rod 10 can be driven to rotate through the connecting rod 15 when the threaded sleeve 14 moves. A servo motor 16 is fixedly connected to the upper end of the base plate 1, and the output end of the servo motor 16 is fixedly connected to the screw rod 13. A transmission assembly is provided at the upper end of the base plate 1.

[0020] Specifically, refer to Figure 2 The transmission assembly includes a rotating motor 4, a gear 5 and a chain 6. The upper end of the base plate 1 is fixedly connected to the rotating motor 4, the output end of the rotating motor 4 and one side of the material transfer auger 3 are fixedly connected to the gear 5, and the outer wall of the gear 5 is movably connected to the chain 6. The rotating motor 4 can drive the material transfer auger 3 to rotate through the gear 5 and the chain 6, thereby feeding the mud inside the feeding box 2.
