Description

Technical Field

[0001] The utility model discloses a silt clearing device, which relates to the field of water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and tidal flat reclamation projects.

[0003] The river channels of water conservancy projects will accumulate a large amount of silt and impurities over time, which requires dredging. If dredging is not carried out for a long time, it will easily lead to blockage of the river channel, reduced water flow and water pollution.

[0004] In the prior art, when dredging is carried out, refer to patent document CN220433781U. The device proposed in the patent document starts the sludge pump machine for suction through the driving motor. A filter screen is arranged inside the suction disc, which can effectively prevent larger stone particles from being sucked into the sludge pump machine. When the sludge enters the sludge collecting box, the extrusion plate is pushed downward by the extrusion plate telescopic rod to squeeze the sludge. After the sludge is squeezed, the water inside the sludge will be discharged from the drainage pipe below. The squeezed sludge will fall from the bottom of the sludge collecting box to the loading vehicle ready for loading. However, in the actual application of dredging, although the device can facilitate the filtering, squeezing and drainage of dredging and is convenient for collection and treatment, when dredging is extracted, the stones or blocks in the dredging will block the filter screen in the suction disc, which is easy to affect the extraction efficiency of dredging, and the stones or blocks will fall into the river channel, which is not convenient for the next dredging work.
