Description

Technical Field

[0001] The utility model discloses a river channel silt cleaning and improvement device for small watershed management, which relates to the technical field of water conservancy engineering. Background Art

[0002] River dredging generally refers to the management of river channels, which is a water conservancy project. Through mechanical equipment, the silt deposited on the riverbed is blown and stirred into turbid water, which flows away with the river water, thereby playing a role in dredging. Therefore, when cleaning river silt, a river silt cleaning device is needed.

[0003] According to the "River Silt Cleaning Device for Small Watershed Management" disclosed in Chinese Patent Publication No. CN218894131U, a high-pressure water gun is provided. Before the river silt cleaning device is used to extract the silt, the silt at the bottom of the river channel is flushed by the high-pressure water gun to disperse the silt agglomerated at the bottom of the river channel, thereby facilitating the silt cleaning device to clean the silt, thereby ensuring the normal progress of the entire silt cleaning work. By providing a screening net, when personnel extract the silt into the silt collection box, the silt and water are separated by the screening net. Therefore, after the silt and water are separated, it is easier to discharge the silt and water, thereby facilitating the progress of the entire silt cleaning work.

[0004] However, the above device has the problem that the silt is flushed by a high-pressure water gun during the extraction process. Although the silt can be cleaned, it is easy to wash up the garbage on the riverbed, causing blockage in the silt extraction pipeline and affecting the silt cleaning work. Utility Model Content
