When the cleaning plate 5 moves in the opposite direction, the impurities fall into the collection box 24 through the impurity outlet hole 9 and the impurity inlet hole 25, and the cleaning plate 5 contacts the inclined surface on the support block 17, and the cleaning plate 5 moves the support block 17, the first movable plate 15 and the card plate 16 upward until the cleaning plate 5 supports the bottom end of the support block 17 to the second avoidance hole 19. At this time, the bottom end of the card plate 16 is no longer located in the card slot 14, and the release The position of the movable seat 8 is limited. The first compression spring 13 pushes the movable seat 8 to move in the opposite direction. When the cleaning plate 5 moves into the filter box 1 through the cleaning hole 6, the end of the movable seat 8 slides into the cleaning hole 6 again, and the second compression spring 34 is initially in a compressed state. The second compression spring 34 applies a thrust to the fixed column 31 and the support plate 27 to make the top of the collection box 24 and the bottom of the fixed box 7 close together. At this time, the bottom of the pressing plate 36 does not contact the support frame 35. When it is necessary to clean the impurities in the collection box 24, the first hydraulic telescopic rod is used. 37 drives the pressing plate 36 to move downward, so that the bottom of the pressing plate 36 presses the support frame 35 and the support plate 27 to move downward, and the collection box 24 and the second support part 28 move downward synchronously with the support plate 27. When the bottom of the collection box 24 contacts the support plate 26, as the support plate 27 continues to move downward, the limit block 30 slides out of the limit groove 29, and the position restriction of the collection box 24 and the second support part 28 can be released. The staff drives the collection box 24 to move so that the collection box 24 is no longer located between the support plate 26 and the fixed box 7, and the removal of the collection box 24 is completed. When the movable seat 8 slides relative to the support seat 10, the movable seat 8 drives the prism 42 to slide relative to the second slide groove 41 and the support shaft 40 through the rotating shaft 38. When the cleaning plate 5 moves in the opposite direction and the movable seat 8 is fixed relative to the fixed box 7, the second movable plate 44 and the toothed plate 53 are driven to reciprocate through the second hydraulic telescopic rod 43. The toothed plate 53 drives the support shaft 40 to rotate periodically forward and reversely through the gear 45.
