Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction, and particularly relates to a high-efficiency water conservancy construction silt removal device. Background Art

[0002] River dredging generally refers to the management of rivers. 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. After searching, the patent with application number 202321597912.2 discloses a highly efficient water conservancy construction dredging device, in which a stirring mechanism is arranged on the top of the frame, and the stirring mechanism includes 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 a first stirring rod, and the output shaft of the driving motor is fixedly connected to a 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 a second stirring shaft, and the outer surface of the rotating shaft is fixedly connected to a second gear.

[0003] However, during actual use, the applicant found that the dredging device lacked a filtering structure for sludge. During the dredging process, the sludge was directly sucked into the sewage pipe by the sewage pump. During this process, large particles of impurities would exist in the sludge. These impurities could easily get stuck in the sewage pipe, thereby hindering the smooth progress of the dredging operation. In view of this, we proposed a high-efficiency dredging device for water conservancy construction. Utility Model Content
