Triangular cutting edge tooth for dredging rake head

Abstract

The invention relates to a triangular cutting edge tooth for a dredging rake head, and belongs to the technical field of dredging engineering. The triangular cutting edge tooth for the dredging rake head is characterized in by being composed of a tooth root, a tooth stem and a tooth edge, wherein the tooth root is used for being installed on a rake head tooth seat of a rake suction boat, and the tooth edge is a triangular cutting edge tooth. The triangular cutting edge tooth has better cutting effect on compact soil compared with other rake teeth of the same series, so that the dredged soil can be fully separated into strips before being excavated and conveyed by the dredging rake head, and the excavation efficiency of the soil is fully improved; and the relatively thin tooth edge and a relatively small tooth head are used for reducing the possibility that clay blocks the rake tooth, so that the negative influence caused by the fact that high-pressure water blowing is not opened so asto ensure the concentration when silty clay dredging is carried out is avoided.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, in particular to a triangular blade tooth for a dredging rake head. Background technique [0002] At present, in the project of dredging dense silty clay by self-propelled trailing suction dredger, due to the high standard penetration base of dense silty clay, high shear strength, fine particles, and high compactness, it brings a lot of difficulties to the dredging process. Difficulty and trouble. Due to the structural limitations of sharp teeth and flat teeth: either the excavation volume is too low after entering the soil, or the soil cannot be broken into the soil. High-pressure flushing will reduce the excavation concentration to a certain extent for dense clay. Therefore, in the construction of dense silty clay, it is time-consuming and laborious, the production efficiency is low, and the consumption of rake teeth is very serious, and there are technical problems such as spendi...

[0002] At present, in the project of dredging dense silty clay by self-propelled trailing suction dredger, due to the high standard penetration base of dense silty clay, high shear strength, fine particles, and high compactness, it brings a lot of difficulties to the dredging process. difficulties and troubles

Due to the structural limitations of sharp teeth and flat teeth: either the excavation volume is too low after entering the soil, or the soil cannot be broken into the soil. High-pressure flushing will reduce the excavation concentration to a certain extent for dense clay

Therefore, in the construction of dense silty clay, it is time-consuming and laborious, the production efficiency is low, and the consumption of rake teeth is very serious, and there are technical problems such as spending more manpower, material resources and financial resources.
