A plurality of grinding balls 5031 are circumferentially distributed at the bottom of the grinding disc 503. A second sliding rod 505 is slidably provided on the transverse plate 504, and one end of the second sliding rod 505 is connected to the grinding disc 503, and the other end of the transverse plate 504 is connected to a connecting plate 507 located on the side of the transverse plate 504 away from the grinding disc 503.

The gear ring 303 drives the movable cylinder 4 to rotate by sliding with the first slide bar 304 and the slide column 502 and the first horizontal arc segment. The movable cylinder 4 drives the lifting rod 605 to rotate around the return cylinder 701 by driving the conical ring plate 401 to rotate synchronously. The lifting rod 605 drives the crossbeam 602 and the scraper 603 to rotate synchronously by sliding with the slide cylinder 604 and rotating with the rotating cylinder 601 and the return cylinder 701.
