Environment-friendly dredging reamer of dredger

Abstract

The invention relates to an environment-friendly dredging reamer of a dredger and belongs to the technical field of dredging. The environment-friendly dredging reamer of the dredger comprises a reamer body and an anti-diffusion hood, and is characterized in that the anti-diffusion hood is composed of a fixed hood body and a movable hood body; the fixed hood body is connected with the movable hood body through a shaft; the movable hood body is connected with a hydraulic cylinder; the movable hood body is controlled to open in a hydraulic structural mode. The sundry cleaning time is shortened, the time utilization rate of dredging of the dredger is improved, and the dredging cost is reduced. According to the scheme, the environment-friendly dredging reamer of the dredger has the advantages of bringing convenience to dredging construction, relieving working intensity of constructors, improving environment-friendly dredging construction efficiency and the like, and has good popularization value.

Description

technical field [0001] The invention belongs to the technical field of dredging, in particular to an environment-friendly dredging cutter. Background technique [0002] At present, when the environmental protection cutter suction dredger carries out environmental protection dredging construction, the environmental protection reamer is responsible for the excavation of the underwater polluted sediment. The hydraulic cylinder between them adjusts the angle of the reamer blade relative to the mud surface to ensure the smoothness of the dredging. In addition, the anti-diffusion cover located outside the reamer blade can prevent the outward diffusion of mud during excavation and reduce the secondary pollution caused by dredging construction. The existing dredging reamer has the following technical problems: 1. The reamer is easily blocked by underwater sundries. Since the number of blades of the environmentally friendly reamer is as many as 12 (the blades of ordinary reamers ar...

Problems solved by technology

The existing dredging reamer has the following technical problems: 1. The reamer is easily blocked by underwater debris

Since the number of blades of the environmentally friendly reamer is as many as 12 (the blades of ordinary reamers are 5 to 6 pieces), and the gap between the blades and the anti-diffusion cover is very small, because there are many underwater debris in lakes in our country, the reamer When dredging, sundries are often stuck in the blade, causing the reamer to not rotate

2. It is difficult to clean the sundries inside the reamer

The sundries cleaning hole of the existing environmental protection reamer is a square structure with a small area, and the upper cover of the cleaning hole and the anti-diffusion cover are connected and fixed by dozens of bolts. When it is necessary to clean the sundries between the blades, It is necessary to manually use a wrench to loosen the bolts on the cleaning hole one by one, and then open the upper cover of the cleaning hole, which not only increases the labor intensity of the construction personnel, but also wastes a lot of effective dredging time
