Problems solved by technology

[0008] During the construction of the cutter suction ship, the reamer blade is in direct contact with the mud surface. Since the reamer blade is in the shape of a circular arc, when it swings left and right to dredge, the dredged mud surface is an arc shape, which affects its dredging performance. Flatness, resulting in low dredging accuracy; and due to the disturbance of the reamer head, the underwater polluted sediment dug by the reamer is easy to spread around the reamer head, causing secondary pollution diffusion

Abstract

The invention relates to a disc type environment-friendly dredging reamer. The disc type environment-friendly dredging reamer comprises a connecting and rotating structure, an angle adjusting hydraulic cylinder, a supporting structure, a reamer body, a reamer hydraulic driving device, a water baffle hydraulic cylinder and a water baffle. The connecting and rotating structure is used for connecting a cutter suction ship bridge and the supporting structure; the supporting structure is used for supporting the reamer hydraulic driving device and the reamer body; the connecting and rotating structure is hinged to the supporting structure through the angle adjusting hydraulic cylinder, and the relative angle between the connecting and rotating structure and the supporting structure is adjusted through stretching of the angle adjusting hydraulic cylinder; the reamer hydraulic driving device is located in the supporting structure and used for driving the reamer body to rotate; the reamer body is located at the bottom of the supporting structure, and the bottom of the reamer body is of a plane structure; and the water baffle hydraulic cylinder is rotatably installed on the supporting structure, the water baffle is located on the periphery of the reamer body and hinged to the water baffle hydraulic cylinder, and the water baffle hydraulic cylinder stretches out and draws back to drive the water baffle to move up and down to adjust the dredging thickness. The dredging flatness is improved, and secondary pollution in the dredging process is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection dredging engineering equipment, in particular to a disc type environmental protection dredging reamer. Background technique [0002] During the construction of environmental protection dredging, the dredger uses its excavating device to dredge the polluted sediment deposited on the bottom of lakes, rivers, etc., and the excavated polluted soil is discharged to the treatment site through the dredge pump installed on the dredger. [0003] Environmental protection dredging construction requires high dredging precision, and at the same time requires the characteristics of reducing the spread of secondary pollution during construction, especially when dredging underwater toxic and harmful pollutants, there are strict requirements for the positioning accuracy of the dredging depth direction; on the other hand, dredging During construction, it is required to minimize the disturbance of t...
