The end of the connecting rod 24 away from the motor 6 is fixedly connected to a rotating ring 25, and the surface of the rotating ring 25 is fixedly connected to a lever 26. When mixing the lightweight plaster gypsum raw materials, the lightweight plaster gypsum powder and other raw materials are poured into the hopper 4, and then the motor 6 is started. The output shaft of the motor 6 will drive the connecting rod 24 to rotate, and the connecting rod 24 will drive the lever 26 to rotate together through the rotating ring 25. The rotating rod 28 penetrates and is rotatably connected to a rotating plate 211, which is located in the connecting box 27 and is rotatably connected to the connecting box 27.
