Recently, a company’s “Excavator Bucket Wheel and Bucket Excavator” project was awarded an invention patent certificate by the State Intellectual Property Office. This achievement marks the company’s breakthrough in the research and development of key equipment for open-pit mining.
In the wheel bucket continuous mining system demonstration project, the wheel bucket excavator is the core equipment for continuous mining operations in open-pit coal mines. The structural performance of its bucket wheel and bucket teeth plays a key role in the efficiency of mining operations, equipment operation stability and service life.
The traditional bucket tooth structure is prone to eccentric wear problems during operation, which will lead to increased excavation resistance, increased tooth edge wear, and even fracture, seriously affecting the continuous and stable operation of mining operations.
This invention aims at the common technical problems in this industry and comprehensively optimizes the structure of the bucket wheel and bucket teeth.
By accurately controlling the projection angle of the tooth edge movement direction at 85° – 95°, the problem of tooth edge eccentric wear is effectively solved and the risk of fracture is reduced.
At the same time, key parameters such as front angle and rear angle are optimized to make the force on the bucket teeth more reasonable.
The bucket teeth adopt a cutting section and connecting section structure, and control precise dimensional standards.
The bucket lip is made of steel bending plates to create a ring-shaped structure, and the direction of movement is fixed through the bending positioning angle, which comprehensively improves the overall structural stability and wear resistance.
This invention patent provides solid technical support for the structural upgrade and performance optimization of key open-pit mining equipment.
It comprehensively improves the mine’s intelligent and efficient production support capabilities, and injects scientific and technological power into the company’s safe, efficient, and high-quality development.
In today’s context of ever-increasing demand for mineral resources, the efficiency and safety of open pit mining are of paramount importance.
Breakthroughs in this technology not only help improve the efficiency of mining operations and reduce equipment failures and maintenance costs, but also bring significant economic benefits to enterprises.
At the same time, this also reflects my country’s innovation capabilities and technical strength in the field of open-pit mining equipment technology, and is expected to enhance the competitiveness of my country’s related products in the international market and promote China’s open-pit mining equipment to the world.
