Technical Field

[0001] The utility model relates to the technical field of river channel desilting, in particular to a river channel desilting device. Background Art

[0002] River dredging generally refers to the management of rivers, 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. River siltation has increasingly affected the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal functions of rivers and promote the rapid and sustainable development of the economy and society, river dredging projects are carried out.

[0003] For example, the patent publication number is CN217175005U, a river channel dredging device, a water spray device sprays water toward the river bottom mud, and the jet device sprays bubbles toward the river bottom mud; the water spray device is detachably fixedly connected to the left side of the hull, and the jet device is detachably fixedly connected to the right side of the hull, and the bottom of the water spray device and the bottom of the jet device are arranged side by side and fixedly connected together by binding parts. The beneficial effect of the utility model is that the device of the utility model can be quickly installed on any hull, and the river bottom mud is initially loosened by the mud shovel, and then the river bottom is further stirred by the water flow, and finally the mud is brought up by the bubbles, so that the river water can carry away the muddy water. However, when the above-mentioned dredging device is in use, the mud shovel will be fixed in the forward direction to shovel mud, resulting in the shovel blade causing greater friction with the waterweed or mud, reducing the mud shoveling efficiency. For this reason, we propose a river channel dredging device to solve the above problems. Utility Model Content
