Opening the conveyor body (1): opening the fixed motor (201), the fixed motor (201) drives the fixed rod (203) to rotate, and drives one of the fixed gears (204) to rotate. Through the meshing of the fixed gear (204) and the connecting gear (205), the connecting rod (206) and the rotating rod (207) rotate. Through the rotation of the rotating rod (207), the conveyor body (1) is driven to rotate, and the conveyor body (1) can be opened; S2, belt speed control of the conveyor body (1): by turning on the rotating motor (402), the rotating motor (402) drives the rotating gear (403) to rotate, and the linkage gear (404) is respectively engaged with the rotating gear (403) and the rotating gear (405), so that the bidirectional threaded rod (406) rotates, and through the limiting of the limiting rod (407), the two moving frames (408) can be driven to move, and the multiple limiting blocks (412) can be driven to move, so that the limiting blocks (412) are close to the speed regulating block (413), and the electric telescopic rod (410) pushes the limiting block (412) to slide in the moving frame (408), so that the limiting block (412) is close to the speed regulating block (413), thereby increasing the friction force and performing speed regulation; S3, cleaning the conveyor body (1): by rotating the fixed rod (203), one of the connected synchronous wheels (307) is driven to rotate, and by the transmission of the synchronous belt, the other connected synchronous wheel (307) drives one of the cleaning rods (304) to rotate, and by the transmission of the synchronous belt and the fixed synchronous wheel (306), the other cleaning rod (304) is rotated, and the water in the water tank (301) is transmitted through the water spray pipe (305) by the transmission pump (302) and sprayed onto the conveyor belt on the conveyor body (1). In addition, with the cooperation of the cleaning rod (304), the conveyor belt on the conveyor body (1) can be cleaned.
