Sludge cleaning equipment for water conservancy project

The utility model belongs to the technical field of hydraulic engineering instruments, and particularly relates to a hydraulic engineering sludge cleaning device which comprises a main body, a sludge suction pipe is arranged at the upper end of the main body, a round shell is arranged in the main body, a fan blade set is pushed to drive a limiting block to enter a rotating rod, a threaded rod is screwed into the rotating rod to fix the rotating rod, and the rotating rod is driven to rotate. A shell is rotated to limit the sludge, a second motor drives a rotating rod to rotate, and the rotating rod drives a fan blade group to rotate, so that the fan blade group crushes large sludge and wood blocks, the large sludge and wood blocks are filtered by a first filter plate and a second filter plate and enter the main body, and then blockage of an internal pipeline of the main body and damage to parts are avoided; an automatic pesticide sprayer is used for scattering pesticide into a round shell, a transmission rod i
