A holding concave rod 61 is welded onto the movable horizontal plate 48. A movable scraper 49 is formed at the upper end of the movable horizontal plate 48. A spring 60 is fitted onto the guide rods 43. The spring 60 is located between the horizontal plate 41 and the movable horizontal plate 48. An outer plate 44 is welded to the outer end of the guide rod 43. A connecting protrusion 45 is welded to the outer plate 44. A connecting shaft 46 is welded to the connecting protrusion 45. A swing plate 47 is rotatably mounted on the connecting shaft 46. The inner end of the swing plate 47 has an arc-shaped structure and abuts against the outer wall of the movable horizontal plate 48.

[0021] The clamp includes a concave member 23 fixed to the inner end of the connecting rope 22. A rectangular hole 24 is provided on the transverse section of the concave member 23. A through rod 27 is welded onto the concave member 23. An L-shaped arm 28 is sleeved on the through rod 27. A side plate 29 is formed on the inner end of the L-shaped arm 28. An oblique hole 30 is provided on the side plate 29. The outer end of the oblique hole 30 extends inward at an inward angle. A pressure rod 32 passes through the oblique hole 30. A clamping plate 31 is welded to the inner end of the side plate 29 on the same side. There is a gap between the clamping plates 31. A connecting outer plate 34 is provided on the outer side of the side plate 29. The outer end of the through rod 27 passes through the connecting outer plate 34. At both ends, the outer ends of the through rod 27 are connected to an outer nut 33 by threads. The outer nut 33 is located on the outer side of the connecting outer plate 34.

[0022] In this embodiment, when scraping sludge off the filter cloth, the operator places one end of the filter cloth between two pairs of clamping plates 31. The operator then rotates the rotating top plate 26. As the top plate 26 rotates, its inner end acts on the middle horizontal plate 35, which in turn moves the two through rods 27. When the through rods 27 move, they act on the inclined holes 30, causing the clamping plates 31 to move axially along the guide rods 43. Finally, the inner wall of the clamping plates 31 is pressed tightly against one end of the filter cloth. The operator then passes the lower end of the filter cloth through the moving horizontal plate 41. Between the horizontal plate 48 and the horizontal plate 41, the operator moves the horizontal plate 48 upward, and then rotates the swing plate 47 so that the inner end of the swing plate 47 abuts against the outer wall of the horizontal plate 48. At this time, the length direction of the swing plate 47 is perpendicular to the horizontal plate 48. As the swing plate 47 swings, the moving scraper 49 on the horizontal plate 48 and the fixed scraper 42 on the horizontal plate 41 will be pressed against the outer wall of the filter cloth. Then, by holding the concave rod 61, the moving scraper 49 and the fixed scraper 42 are moved downward, and the sludge on the filter cloth is scraped off by the moving scraper 49 and the fixed scraper 42.
