Thereby, the two movable plates 36 located at the inner sides of the left and right ends of the sedimentation tank 1 can be controlled to move synchronously and approach each other through the installation rod 35. At this time, the movable plates 36 first move on the outside of the positioning rod 38 in a direction away from the bearing frame 51, and carry the load. The frame 51 is stationary, and now the protruding rod 37 positioned at the bottom of the movable plate 36 can extrude the movable rod 41 provided with a guide groove on the top, so that it drives the mud scraper 43 to rotate with the fixed shaft 42 as the center of the circle until the mud is scraped.
