Through the sealing gaskets 5, water seepage from inside the baffle 8 can be prevented. Sealing strips 19 are attached to both the left and right ends of the baffle 8. The sealing strips 19 are fixedly connected to the inside of the upper sides of the left and right ends of the connecting bracket 17. A scraping surface 18 is provided on the upper right side of the connecting bracket 17. Through the scraping surface 18, the side surface of the baffle 8 can be cleaned. A conveyor belt 4 is installed on the upper side of the lifting plate 11. Air flotation scrapers 3 are fixedly connected to the conveyor belt 4, and four air flotation scrapers 3 are provided on the conveyor belt 4. Through the conveyor belt 4, the air flotation scrapers 3 can be moved. Limiting sliders 12 are fixedly connected to both the front and rear sides of one end of the fixing frame 9 close to the lifting plate 11. The limiting sliders 12 are slidably connected to limiting slide rails 13. The limiting slide rails 13 are provided inside the front and rear ends of the lifting plate 11.
