under the pushing action of the track scraper 2066, the track scraper 2066 is pushed into the separating unit 4 along the surface of the arc plate 2033 to separate, and when the track scraper 2066 moves to the part of the arc plate 2033 close to the separating unit 4, the scraping rail 3023 and the auxiliary rail 3022 turn into the enlarged rail 30231, so that the movement range of the secondary pulley 20633 and the tertiary pulley 20673 is enlarged, the synchronous frame 2063 is extended, the track scraper 2066 at the bottom of the synchronous frame 2063 is more attached to the arc plate 2033, further, sludge on the arc plate 2033 is cleaned more cleanly, and when the auxiliary rail 3022 passes through the enlarged rail 30231, the sludge enters the cleaning rail 30221, and further the movement range of the tertiary pulley 20673 is further enlarged, so that the cleaning plate 20672 pushes and cleans the sludge on the surface of the track scraper 2066, and the sludge is pushed into the separating cavity 403;
the auxiliary rail 3022 moves beyond the cleaning rail 30221 and the scraping rail 3023 moves beyond the expanding rail 30231, so that the three-stage pulley 20673 and the secondary pulley 20633 are restored to the movement range before the expanding rail 30231.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
