A reamer used for suction cutters to avoid being entangled by underwater garbage

Abstract

The invention provides a reamer used for cutter suction boats to avoid being entangled by underwater garbage, including a main knife and wing knives, the main knife includes an annular base and a knife arm, the knife arm is in the shape of a petal bent inward, and there are multiple knife arms There is a certain gap between them and the center is symmetrically fixed on the annular base. The wing blades include upper wing blades, middle blade blades and lower blade blades. The upper blade blades, middle blade blades and lower blade blades are all arc-shaped and crescent-shaped. The wing knives, middle wing knives and lower wing knives are fixedly distributed on the outer surface of the knife arm at a certain distance from top to bottom and are inclined upward at a certain angle relative to the knife arm from left to right. The dimensions of the upper wing knife, middle wing knife and lower wing knife are in order Reduced size, blades are provided on the edges of the knife arm, upper wing knife, middle wing knife and lower wing knife, and the reamer can automatically cut sundries. It can face various complicated underwater environments and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of dredging engineering, in particular to a reamer used for a cutter suction ship to avoid being entangled by underwater garbage. Background technique [0002] As the main part of the cutter suction ship, the reamer rotates and cuts the soil layer through the power device, deforms and breaks the separated soil layer and mixes it with water to form mud, which is then pumped to the centralized sludge treatment center through pipelines. The traditional reamer is mainly composed of a single-form knife arm with a simple structure. However, the knife arm will encounter various complex environments during underwater operations, such as the obstruction of aquatic plants and the entanglement of fishing nets. The traditional knife arm is easily entangled by aquatic plants, fishing nets and other debris, which greatly affects the reamer. The working efficiency is high, and the wringer suction device will be damaged in...

The traditional reamer is mainly composed of a single knife arm, with a simple structure

However, the knife arm will encounter various complex environments during underwater operations, such as the obstruction of aquatic plants and the entanglement of fishing nets. The traditional knife arm is easily entangled by aquatic plants, fishing nets and other debris, which greatly affects the reamer. The work efficiency is high, and the wringer suction device will be damaged in severe cases
