Water conservancy ecological engineering desilting device

The invention discloses a water conservancy ecological engineering desilting device, and relates to the technical field of river channel desilting, the water conservancy ecological engineering desilting device comprises a walking mechanism, a hydraulic mechanical arm and a desilting box; a sliding groove perpendicular to the walking direction is formed in the surface of the walking mechanism, a sliding block is slidably connected into the sliding groove, and the sliding block is driven by a driving mechanism and reciprocates in the sliding groove. A base of the hydraulic mechanical arm is installed on the sliding block. The desilting box is connected to the working end of the hydraulic mechanical arm, a plurality of suction ports and a plurality of telescopic reamer mechanisms are arranged at the bottom of the desilting box, water conservancy ecological engineering desilting and obstacle removing shovels are fixed to the two side walls of the desilting box, cutting edges of obstacle removing shovel bodies fac
