The dredging device used by the river channel environmental protection construction department faces a series of challenges during operation. In order to prevent larger objects such as stones from entering the crushing mechanism inside the device and damaging the crushing knife, a filter screen is usually set at the entrance of the device.

The outer side surface of 11 is meshed, so that the third gear 703 will be pushed by the spur rack 711 when it moves, and point a of the second guide groove 706 is farther away from the pump 3 than point b of the second guide groove 706, and point c of the second guide groove 706 is closer to the pump 3 than point d of the second guide groove 706, so that the second guide rod 707 can move to the right side of the second guide groove 706 when it moves to point a and moves back, and can move to the left side of the second guide groove 706 when the second guide rod 707 moves to point c of the second guide groove 706.

[0035] The operating steps of a dredging device used by a river environmental protection construction department are as follows: start the hull 1 to drive the collecting box 8 to collect silt, start the bidirectional motor 6101 to drive the first push plate 6207 to move horizontally and swing back and forth to push the blockage on the inside of the filter screen 5 to the outside, and at this time, the bidirectional motor 6101 drives the rotating mechanism 7 to rotate to push the pushed-out blockage farther.

[0036] When cleaning the silt, small stones and other obstructions will clog the holes inside the filter 5 and need to be cleaned. The specific operations are as follows:

[0037] The bidirectional motor 6101 is started to drive the first rotating shaft 6102 and the crushing blade 6103 to rotate to crush the sludge after filtering. When the bidirectional motor 6101 rotates, it drives the first gear 6105 to rotate, drives the annular gear belt 6106 to rotate, so that the first connecting rod 6109 moves, and the first slider 6108 and the sliding plate 6110 move. Because the connection mode of the sliding plate 6110 and the collecting box 8 is a sliding connection, and the connection mode of the sliding plate 6110 and the first slider 6108 is a sliding connection, when the first connecting rod 6109 moves to the turning position of the annular gear belt 6106, the first connecting rod 6109 drives the first slider 6108 to slide and returns to the annular gear belt 61 06, the sliding plate 6110 realizes reciprocating motion, driving the baffle plate 6202 and the first connecting plate 6205 to perform reciprocating motion, causing the first push plate 6207 arranged on the inner side of the third hole 6206 to perform reciprocating motion. Because the appearance structure of the first guide groove 6203 is wavy, and the first guide groove 6203 and the first guide rod 6204 are matched in a clearance fit, the first guide rod 6204 is pushed by the edge of the first guide groove 6203 to perform reciprocating motion, causing the push rod 6208 to perform reciprocating motion, pushing the blockage on the inside of the filter net 5 out of the inner hole of the filter net 5, reducing blockage, reducing the number of times construction personnel perform salvage and cleaning, reducing the extra workload brought to construction personnel, and improving construction efficiency.

[0038] When the sliding plate 6110 reciprocates, it drives the second connecting plate 701 and the fourth connecting plate 710 arranged on the inner side of the first groove 702 to reciprocate, and drives the third gear 703 and the second gear 704 to reciprocate. Because the height of the third gear 703 is greater than the height of the second gear 704, and the outer side surface of the third gear 703 is meshed with the outer side surface of the spur rack 711, the third gear 703 and the second gear 704 are meshed, so that the third gear 703 and the second gear 704 are rotated, and the two rotating rods 708 and the second push plate 709 are rotated, pushing the blockage just pushed out by the push rod 6208 to the side away from the filter screen 5, so that the blockage can be away from the filter screen 5, thereby reducing the possibility of blockage again.

[0039] Because point a of the second guide groove 706 is farther away from the pump 3 than point b of the second guide groove 706, and point c of the second guide groove 706 is closer to the pump 3 than point d of the second guide groove 706, the second guide rod 707 can move to the right side of the second guide groove 706 when it moves to point a and then moves back. Two spur racks 711 are symmetrically arranged about the central axis of the third connecting plate 705, so that the entire second connecting plate 701, the third gear 703 and the second gear 704 move to the right, and the two rotating rods 708 and the second push plate 709 rotate on the side farther away from the filter screen 5, pushing the blockage just pushed to the side farther away from the filter screen 5, thereby further reducing the possibility of blockage again.
