Description

Technical Field

[0001] The invention relates to the field of waterway clearing devices, in particular to a waterway dredging device. Background Art

[0002] Channel dredging is the process of removing underwater silt from a channel using a dredger or other tools. Channel dredging is one of the main means of developing channels, increasing and maintaining channel dimensions. Compared with other channel engineering projects, channel dredging is more flexible and has quick results. The channel dimensions increase immediately after dredging, and the construction is relatively simple, without consuming a large amount of engineering materials and manpower.

[0003] The existing channel cleaning method is to install a dredging device on a dredging ship, including a bucket, a connecting arm, a sludge extraction pipeline, a sludge pump and a motor. One end of the connecting arm is movably installed on the hull, and the other end is connected to the bucket and lifted by a crane. The sludge extraction pipe is installed on the connecting arm, one end of which is connected to the bucket, and the other end is connected to the sewage pump installed on the hull. When working, the connecting arm is lowered into the water by the crane, the bucket contacts the riverbed, and then the hull is slowly started to drive the bucket at one end of the riverbed to scrape the sludge into the bucket. Then the sludge pump extracts the sludge in the bucket and inputs it into the sludge storage tank of the bed through a pipeline, thereby completing the sludge cleaning. However, when the bucket moves on the riverbed to dredge, there are a lot of debris in the river channel, and the sludge will combine with other substances to form sludge blocks. The sludge blocks can easily block the suction end of the sludge extraction pipeline. For this reason, a channel dredging device is needed to facilitate the breaking of the sludge blocks and facilitate the suction of the sludge extraction pipeline. Summary of the invention
