Flushing double-sided plough tooth for dredging rake head

Abstract

The invention relates to a flushing double-sided plough tooth for a dredging rake head and belongs to the technical field of dredging engineering. The flushing double-sided plough tooth for the dredging rake head is characterized by being composed of a toothholder and a tooth body; the toothholder is mounted in a position of a wear-resistant block of the rake head and the tooth body is mounted onthe toothholder; tooth wings are arranged on two sides of the lower end of the tooth body, and the tooth wings are of backwards extended structures; and a flushing channel is formed in the middle of atooth trunk. The flushing double-sided plough tooth for the dredging rake head has the advantages of being simple in structure and convenient to assemble, increasing the disturbing force of compact soil, finishing penetrating into, loosening, breaking and turning soil continuously and effectively, improving the efficiency of excavating the compact soil, reducing the labor intensity of seamen, shortening the construction period, being suitable for excavating the compact soil and the like.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, in particular to a double-sided plow tooth with flushing for a dredging rake head. Background technique [0002] At present, self-propelled trailing suction dredgers have brought many difficulties and troubles to the dredging process due to the high density and good particle gradation of compact soil in dredging projects of dense soil. Due to the structural limitation of sharp teeth and flat teeth, the ability to break the soil after entering the soil is insufficient or cannot be effectively penetrated into the soil; even if the plow teeth are used for excavating it, it cannot effectively penetrate the soil or the resistance after entering the soil is too large to achieve continuous soil breaking. Therefore, in the engineering construction of compact soil quality, it is time-consuming and labor-intensive, the labor intensity is high, the production efficiency is low, the cost is high...

AI Technical Summary

Problems solved by technology

[0002] At present, self-propelled trailing suction dredgers have brought a lot of difficulties and troubles to the dredging process due to the high density of compact soil and good particle gradation in the dredging project of compact soil.

Due to the structural limitations of sharp teeth and flat teeth, the ability to break the soil after entering the soil is insufficient or cannot be effectively penetrated into the soil; even if the plow teeth are used for excavation, it is also unable to effectively penetrate the soil or the resistance after entering the soil is too large to achieve continuous soil breaking.

Therefore, in the construction of dense soil, it is time-consuming and labor-intensive, with high labor intensity, low production efficiency, high cost, and technical problems such as spending more manpower, material resources and financial resources.
