During the movement of the lead screw nut, the hinge rod is driven to pull the sector plate to slide on the slide rail frame, thereby realizing the scaling between the five sector plates; the diameter of the circumscribed circle of the scaled trajectory is greater than the minimum side length of the shell part ;

S4. The control system controls the opening of the steam generating device, and sends high-temperature steam to the steam access pipe in the first cleaning assembly through the air supply branch pipe, and the high-temperature steam is sprayed downward from the nozzles on the fan-shaped plate; the second cleaning assembly is located on several tops Driven by the lift cylinder, it moves upwards, so that the steam nozzle passes through the gap of the transmission line and moves upwards close to the inside of the shell, thereby cleaning the inside of the shell;

S5. The steam spray gun on both sides of the shield is adjusted by the hydraulic lift seat according to the size and position of the screw, so that the nozzle and the outer surface of the shell parts form an angle, and then the shell parts are cleaned with high pressure steam from multiple directions. The grease on the surface and inside of the housing falls into the grease collecting device.
