The first roller support 1.3 and the second roller support 2.3 are both installed on the vertical plate of the bow water surface of the ship body.

[0028] The scraper 5 is made of polyurethane elastomer and is divided into left and right parts, and the left and right parts of the scraper 5 are attached to the towing anchor rope 4 through the extrusion of the clamping mechanism 8; the clamping mechanism 8 comprises two guide chambers 8.1 and two elastic sheets 8.2, the guide chamber 8.1 is installed inside the second roller support 2.3, the elastic sheet 8.2 and the scraper 5 are sequentially inserted into the inner cavity of the guide chamber 8.1, and the scraper 5 is pressed against the towing anchor rope 4 under the elastic force of the elastic sheet 8.2.

[0029] The brush 6 is divided into left and right parts and comprises a first brush 6.1 adjacent to the scraper 5 and a second brush 6.2 adjacent to the second roller cylinder 2.1, the brush head of the first brush 6.1 is made of bronze or stainless steel and has a hardness of 20HRC-30HRC, and the brush head of the second brush 6.2 is made of wear-resistant resin, preferably nylon.

[0030] The left and right parts of the brush 6 are attached to the towing anchor rope 4 through the extrusion of the clamping device 9; the clamping device 9 comprises four guide shafts 9.1 and four springs 9.2, the guide shaft 9.1 is connected with the brush 6 and is inserted into the through hole of the second roller support 2.3, the guide shaft 9.1 can axially slide in the through hole of the second roller support 2.3, the spring 9.2 is sleeved on the periphery of the guide shaft 9.1, and the two end faces of the spring 9.1 are respectively abutted against the brush 6 and the second roller support 2.3; the brush 6 is pressed against the towing anchor rope 4 through the elastic force of the spring 9.1.

[0031] Four air jet nozzles 7 located on the water surface are further arranged around the towing anchor rope 4 between the first roller 1 and the second roller 2, the four air jet nozzles 7 are annularly staggered around the towing anchor rope 4 and are uniformly arranged along the circumference, and the air jet nozzles 7 are in communication with the exhaust pipe of the pneumatic dredging pump.

[0032] When the dredging operation is carried out, the anchor winch drum rotates to tighten the towing anchor rope 4 to drag the ship body forward, the silt-stuck towing anchor rope 4 passes through the third roller 3.1, the scraper 5, the brush 6.1, the brush 6.2 to the second roller 2.1 in turn, and then turns up to extend to the first roller 1.1, and then turns horizontally to extend to be wound on the anchor winch drum on the ship body deck.
