A dredging device for hydraulic culverts

Abstract

This utility model discloses a dredging device for hydraulic culverts, comprising a platform, with movable tracks fixedly installed at both ends of the platform's bottom. A suction disc is movably inserted through the middle of the platform, and a discharge pipe is fixedly installed on the top of the suction disc. A fixed box is fixedly connected to the right end of the platform's top, and a guide pipe is movably connected to the upper end of the fixed box via a bearing. A flushing nozzle is fixedly installed at the bottom of the guide pipe, a rotary joint is fixedly installed on the left side of the guide pipe, and a water supply pipe is fixedly installed on the left side of the rotary joint. This utility model, through the movable tracks, can move along the interior of the hydraulic culvert during dredging operations. Through the water supply pipe, rotary joint, guide pipe, and flushing nozzle, high-pressure flushing of the silt at the bottom of the hydraulic culvert is performed while water is being transported by an external high-pressure water pump, causing the silt to become fluid.
