The transmission shaft 16 rotates to make the connecting plate 17 drive the scraper 18 to rotate. The scraper 18 rotates along the inner wall of the discharge barrel 1, and the particles adhering to the discharge barrel can be removed. 1. The paint on the inner wall is scraped off in time, and at the same time, the double-axis motor 9 rotates to rotate the connecting rod 8, and the connecting rod 8 rotates to rotate the rotating shaft 7.
