[0024] Through the implementation of the above technical solution, the connecting cylinder 1 in the utility model is docked with the feed port of the rice processing equipment. When in use, the rice to be processed is poured downward through the bucket body 4. When the amount of rice poured is large, in order to avoid the blockage of the square cylinder 3, the side shafts 13 on both sides are driven to rotate through the meshing transmission of the dual-axis motor 15 and the first bevel gear 16 and the second bevel gear 17, thereby driving the two cams 14 to rotate synchronously. Under the rotation of the cam 14, the plate body 11 is pushed to move vertically, thereby pushing the square cylinder 3 located at the upper end of the connecting cylinder 1 to move vertically. Under this reciprocating movement, the rice and the inner wall of the square cylinder 3 are continuously sliding relative to each other, which plays a good dredging role, thereby avoiding blockage.
