[0002] Water is a valuable resource that is indispensable to human production and life. Water conservancy projects are projects built by controlling and allocating groundwater and surface water in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. In order to keep the river clean and avoid blockage, dredging equipment is needed to dredge the river regularly.

[0003] According to the description of a river channel desilting device for water conservancy projects disclosed on the patent website (authorization announcement number: CN216839632U), "The utility model discloses a river channel desilting device for water conservancy projects, including a shell, a filter tank and a scraper. The top of the shell is connected to a silt suction pump by bolts. A filter tank is arranged at the bottom of the silt suction pump in the shell. A material guide tank is arranged in the filter tank. A material guide pipe is arranged at the feed end of the silt suction pump. The discharge end of the silt suction pump is connected to the material guide tank through a pipeline. A screw rod is installed on one side of the shell through a bearing. A corresponding screw block is arranged on the periphery of the screw rod. One side of the screw block is connected to a sliding bracket by bolts. The utility model is a river channel desilting device for water conservancy projects.
