Abstract

The invention relates to an underwater dredging machine which comprises a frame; both sides of the frame are provided with self-walking chasses; the front end of the frame is provided with a lifting frame, and the rear end thereof is provided with a hydraulic workstation and a submersible mud pump; the front end of the lifting frame is provided with a dredging device, and the dredging device comprises a cutter, a scraper and a crusher; a lifting oil cylinder is arranged between the lifting frame and the frame; both ends of the submersible mud pump are respectively connected with a mud suction tube and a mud pipe; and the top of the mud suction tube is connected with the crusher. The hydraulic workstation supplies power to the self-walking chasses, the cutter, the lifting oil cylinder, the submersible mud pump and the crusher. The underwater dredging machine can effectively improve the concentration of dredging mud so that the concentration can reach 20 to 50 percent and is far higher than 10 to 15 percent of general dredgers, and ensure the neatness of the river bed cross section after dredging.

Description

technical field [0001] The invention relates to the field of environment-friendly dredging machinery, in particular to an underwater dredging machine for urban rivers that cleans up a lot of rubbish and sundries. Background technique [0002] With the continuous improvement of the level of urban construction, the requirements for urban environmental protection are also increasing. As the focus of urban environmental governance, the governance of urban rivers has also undergone tremendous changes. Since most of the urban river courses have completed the shaping of the riverbed section and the hardening construction of the retaining wall and revetment, the treatment of urban rivers has changed from the past large-scale earthwork clearing, river bed shaping and hardening of the retaining wall and revetment to normal protective dredging . This kind of dredging is a long-term dynamic project with continuous circulation, which cannot be done once and for all. This normalized pr...
