Description

Technical Field

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

[0002] River dredging generally refers to the management of river channels, which is a water conservancy project. There are currently many ways to dredge rivers. The most common one is to use mechanical equipment to blow the silt deposited on the riverbed into turbid water, which flows away with the river water, thereby playing a role in dredging.

[0003] After searching the Chinese patent with publication number CN213508627U, a river dredging device is disclosed. When working, with the movement of the hull, the dredging mechanism continuously scrapes the silt from the river channel, the silt extraction component absorbs the above silt, and discharges it to the first bin through the pipeline. Under the action of gravity, the silt will sink to the bottom of the first bin, that is, sink to the partition plate, the filter drainage component intercepts the silt, and filters the silt, and discharges the filtered clean water to the second bin, and the filter drainage component discharges the clean water back to the storage bin into the river.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The silt at the bottom of the river channel is only processed by the dredging machine head, and then the silt is absorbed by the suction pump. However, the silt is not guided and it is difficult to flow accurately to the input end of the suction pump. Some silt will flow away from both sides of the suction pump, resulting in poor dredging effect. In addition, the silt is mixed with a large amount of water and sucked into the suction pump, which affects the silt extraction speed and reduces the dredging efficiency of the river channel.
