The invention discloses a
sludge cleaning device for a river channel cleaning ship. The
sludge cleaning device comprises a motor chamber, lifting hooks, clamping plates, connecting rings, guide steelwire
rope groups, a digging hopper, hanging rings, brackets,
pollutant storage boxes, moving
doors, clamping grooves, a rotary disc, a
flapping cover, a pushing disk and water outlet holes. The sludgecleaning device has the beneficial effects that through the arrangement of the clamping grooves in both the inner walls bottoms of the two sides of the brackets and the placement of the
pollutant storage boxes inside the clamping grooves,
sludge shoveled by a digging hopper is stored in the
pollutant storage boxes, so that during the process of cleaning the sludge, the digging hopper is not required to be withdrawn back to the water surface to pour out the dug sludge onto the ship
deck every time the sludge is cleaned. Through the installation of the moving
doors on the side wall of the pollutant storage boxes, the pollutant storage boxes are controlled by the moving
doors to open or close, when the digging hopper raises up to the positions of the moving doors, the moving doors open automatically and flips at 60 degrees, the moving doors at the time right abut against the bottom of the digging hopper, and the pushing disk installed inside the digging hopper at the time is started, andthe sludge in the digging hopper is directly pushed into the pollutant storage boxes.
