Description

Technical Field

[0001] The utility model relates to the technical field of silt clearing devices, in particular to a water conservancy silt clearing device. Background Art

[0002] Hydraulic dredging in water conservancy projects generally refers to the process of regulating the river channel. The silt deposited on the riverbed is blown and stirred into turbid water by mechanical equipment, and then flows away with the river water, thereby playing a role of dredging. The current hydraulic dredging device is easily blocked by the agglomerated silt when the sludge suction head is used to suck the sludge, which will reduce the efficiency of sludge suction and dredging.

[0003] Therefore, in order to solve the above problems, the utility model with patent publication number CN219886991U discloses a water conservancy silt removal device, which can perform silt removal work through the cooperation of a sludge suction pump, a stirring device and a sludge suction head. When the surface of the sludge suction head needs to be cleaned, the output end of the motor drives the screw to rotate, the screw drives the screw sleeve to move downward, the screw sleeve drives the lifting ring to move downward, and the lifting ring drives the brush to move downward. During the movement of the brush, the silt agglomerated on the surface of the sludge suction head is cleaned. Although it is convenient to clean the silt on the surface of the sludge suction head, when the sludge suction work is performed, stones and other debris in the sludge will also enter the sludge suction head, which will still cause certain blockage to the sludge suction head. The cleaning force of the brush is relatively small, which is not convenient for cleaning stones and other debris in the sludge suction head, thereby reducing the dredging efficiency in water conservancy projects.
