Embodiment

[0029] A dredging device for water conservancy projects, comprising a conveying cylinder 1, and the conveying cylinder 1 is made of wear-resistant steel. A bucket 2 is arranged at the silt inlet at one end of the conveying cylinder 1, and the bucket 2 is a funnel-shaped structure with a large open end. The bucket 2 is connected to the sludge inlet through a connecting hose 24 . The bottom end of the open end of the bucket 2 is provided with a plurality of teeth 23, the teeth 23 are trapezoidal structures, and the teeth 23 are convenient for inserting the bucket 2 into the mud and shoveling the mud into the bucket 2.

[0030] The bucket 2 is connected with the conveying drum 1 through the connecting plate 19 , the connecting plate 19 is fixed on the conveying drum 1 , and the bucket 2 is hinged with the connecting plate 19 . The conveying drum 1 is provided with an angle adjusting structure for adjusting the angle of the bucket 2 . The angle adjustment structure includes a cy...

Abstract

The desilting device comprises a conveying cylinder, a bucket is arranged at a silt inlet in one end of the conveying cylinder, the bucket is connected with the conveying cylinder through a connecting plate, the bucket is hinged to the conveying cylinder, an angle adjusting structure for adjusting the angle of the bucket is arranged on the conveying cylinder, and a water filtering structure is arranged at the other end of the conveying cylinder. A silt outlet is formed in the side wall of the end, close to the water filtering structure, of the conveying cylinder, a mortar pump is arranged on the silt outlet, and an outlet of the mortar pump is connected with a mud conveying pipe. The conveying cylinder is connected with a sliding plate through a lifting mechanism, the sliding plate is arranged on a mounting plate and slidably connected with the mounting plate through a sliding mechanism, and the two ends of the mounting plate are arranged on a dredging ship. According to the desilting device for the water conservancy project, the problems that an existing desilting device is complex in structure, high in manufacturing cost and low in desilting efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a dredging device for hydraulic engineering. Background technique [0002] In water conservancy projects, river dredging is a very important process in river maintenance. River dredging generally uses mechanical equipment to blow and stir the silt deposited on the bottom of the river into a mixed water form, which flows away with the river, thus playing a role of dredging. The dredging of the existing river channels is generally carried out by a dredging vessel. The dredging vessel is equipped with a cutter suction head, and the dredging head is used to disperse the sludge and mix it with water, and then the mixed mud and water are sent to the dredging vessel through a conveying pipe. The structure of the twisted suction head is relatively complicated, the weight is heavy, and the cost is relatively high. The cutter head generally sinks to the bottom of the river ...
