Description

Technical Field

[0001] The utility model relates to the technical field of silt removal devices, in particular to a high-efficiency silt removal device for water conservancy construction. 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, thus playing a role in dredging. There are many ways to dredge, and the main methods are divided into three types: dry water operation, water operation and environmental dredging. Dry water operation uses a high-pressure water gun of a hydraulic flushing and excavation unit to flush the bottom mud, disturb the bottom mud into mud, and the flowing mud gathers in a pre-set low-lying area, where it is sucked up by a mud pump and transported by pipeline to the yard or slurry collection pool on the shore.

[0003] For example, the utility model with announcement number CN220225514U discloses a high-efficiency dredging device for water conservancy construction, wherein a stirring mechanism is arranged on the top of the frame, and the stirring mechanism comprises a return box, and a driving motor is fixedly installed on the inner wall of the return box, and one end of the output shaft of the driving motor is fixedly connected to the first stirring rod, and the output shaft of the driving motor is fixedly connected to the first gear, and a rotating shaft is arranged on both sides of the first gear, and one end of the output shaft of the rotating shaft is fixedly connected to the second stirring shaft, and the outer surface of the rotating shaft is fixedly connected to the second gear. During use, the first stirring rod and the first gear are driven to rotate by the arranged driving motor, and the first gear drives the second gear to rotate at the same time, so that the rotating shaft and the second stirring rod rotate, and by arranging three stirring rods to rotate at the same time, the range of sludge that needs to be stirred can be made wider, and there is no need to frequently move the equipment, which saves time and greatly improves work efficiency.

[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing water conservancy construction dredging devices need to pump out the water in the river before dredging work can be carried out. Otherwise, dredging work directly in the water will easily cause the silt to spread with the water flow, resulting in a significant reduction in the dredging effect. Pumping water from the river will reduce the dredging efficiency of the river.

[0005] Therefore, a high-efficiency water conservancy construction silt removal device is proposed. Utility Model Content
