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 environmental protection reamer is as many as 12 (common reamer blades 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 the lakes of 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

Embodiment 1

[0035] An environment-friendly dredger dredging reamer includes a reamer and an anti-diffusion cover, the anti-diffusion cover is composed of a fixed cover and a movable cover, and the anti-diffusion cover is in the shape of a circular platform. The total length of the anti-diffusion cover is 2m, and the cone angle is 30°. The movable cover is equipped with a rotating trunnion plate, and the fixed cover is equipped with a pin trunnion plate, and the movable cover and the fixed cover are connected together through a pin shaft. The hydraulic cylinder is installed on the fixed cover, and the piston of the hydraulic cylinder is connected with the movable cover. The hydraulic structure controls the opening of the movable cover. The opening angle of the movable hood is 60°. The thickness of the movable cover panel is 8mm. There are 3 transverse reinforcing ribs and 3 longitudinal reinforcing ribs distributed on the movable cover, and the reinforcing ribs are made of steel and wel...

Abstract

The invention relates to an environment-friendly dredger dredging reamer, belonging to the field of dredging technology. The environment-friendly dredger dredging reamer comprises a reamer and a non-proliferation cover, and is characterized in that the non-proliferation cover consists of a fixed cover and a movable cover, wherein, the fixed cover is connected with the movable cover by a shaft, and the movable cover is connected with a hydraulic cylinder and is controlled to be opened by a hydraulic structure mode. The dredging reamer saves the time used for clearing out sundries, improves the utilization rate of dredging time of a dredger, and reduces the dredging cost. The proposal has the advantages of being convenient for dredging construction, reducing working strength of construction personnel, improving the construction efficiency of environment-friendly dredging, etc. The invention has good promotional 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 environmental protection reamer is as many as 12 (common reamer blades are 5 to 6 p...
