Description

Technical Field

[0001] The utility model relates to the technical field of river channel desilting devices, and more specifically to a river channel desilting device for water conservancy projects. Background Art

[0002] River dredging is of great significance to water conservancy projects and overall environmental management. It is not only related to the effective use of water resources and flood prevention, but also directly affects the health of the ecological environment and the sustainable development of the economy. At present, the equipment is simple and low-cost, but its working environment is demanding and has high requirements for the composition of silt. It can only clean mud or fine sand, and it is difficult to clean thicker silt. It is impossible to separate the resources in the silt for reuse, resulting in waste of resources.

[0003] Since the current river dredging equipment extracts the silt in a unified manner, the usable sand and gravel in the silt are wasted. The thicker silt is difficult to extract, causing blockage of the machine and seriously affecting the cleaning efficiency. Therefore, the problem is solved by crushing the silt and recovering the sand and gravel. Utility Model Content
