The two groups of gears in the gear box 67 rotate, and the cleaning cylinder 65 and the water from the water hole can be used to clean the rotating toggle member 66.

[0051] When it is necessary to clean the conveyor belt 1, water is injected into the nozzle 76 by the support plate 75 to spray water or cleaning liquid, and then the third motor 7a is started to work. The third motor 7a drives the driving wheel 72 to rotate, and the driving wheel 72 drives the belt 73 to make the driven wheel 744 rotate, and the sliding shaft 743 in the middle of the driven wheel 744 rotates. During the rotation of the sliding shaft 743, the rotating cylinder 745 in the middle can rotate, and the dial plate 746 and the cleaning layer 747 on its outer side begin to clean the surface of the conveyor belt and scrape off the impurities on its surface.
