Description

Technical Field

[0001] The utility model relates to the technical field of silt removal equipment, and more specifically, to silt removal equipment for water conservancy construction. Background Art

[0002] During water conservancy construction, if a river channel with a lot of silt is encountered, the water level of the river channel will rise due to the influence of the silt. Therefore, the silt needs to be cleared elsewhere before subsequent water conservancy construction can be carried out. Currently, the silt deposited on the riverbed is mainly removed by mechanical equipment or other equipment, thereby playing a role in dredging.

[0003] At present, during dredging, some people use sludge suction equipment to extract and discharge the riverbed sludge. When the suction equipment is in use, the suction end of the sludge pipe is placed in the river sludge, and then the sludge pump is started to suck and discharge. Although dredging operations can be achieved to a certain extent, the river channel may contain hard objects such as stones and branches. The use of suction will cause pipe blockage and even damage to the pump body, which greatly affects the dredging efficiency. Utility Model Content
