River channel dredging equipment for hydraulic engineering construction

The river channel dredging equipment for hydraulic engineering construction comprises a separation barrel, a filter box and a silt suction pipe, the end of the silt suction pipe extends into the separation barrel, the inner wall of the separation barrel is rotationally connected with a rotating rod, and the surface of the rotating rod is provided with an auger blade matched with the inner wall of the separation barrel; a driving motor used for driving the rotating rod to rotate is arranged at the end of the separating cylinder, and a first discharging opening and a second discharging opening are formed in the lower surface of the separating cylinder. According to the river channel dredging equipment for hydraulic engineering construction, when sludge at the bottom of a river is sucked into a separation cylinder through a sludge suction pipe, a rotating rod can be driven to rotate through rotation of a driving motor, the rotating rod rotates to drive an auger blade to convey the sludge, and water in the sludge
