Cutting mechanism of stoping machine with large speed changing range

Abstract

The invention relates to a cutting mechanism of a stoping machine with a large speed changing range. The mechanism comprises a shell, a motor, a multi-stage speed changing transmission mechanism, a planet reduction mechanism and a cutting roller. Power is transferred to the cutting roller from the motor through the multi-stage speed changing transmission mechanism and the planet reduction mechanism. By replacing any one or more places of a front speed changing mechanism and a middle speed changing mechanism in the motor, the planet reduction mechanism and the multi-stage speed changing transmission mechanism of different parameters, a large speed changing range is achieved to fit stoping of hard materials. The mechanism can be suitable for cutting materials of different hardness, corrosionresistance and characteristics, and can solve the problem that the cutting teeth of the existing cutting mechanism of the stoping machine are easily worn and broken well, and the cost performance ofinput and output is high.

Description

technical field [0001] The invention relates to a cutting mechanism of a mining machine, which is characterized in that it has a large variable speed range and can adapt to the mining of hard materials. Background technique [0002] The drum type cutting mechanism is developed from the coal cutting arm. Based on the excellent ability of the coal cutting arm to continuously and efficiently mine coal and other brittle materials, it has gradually appeared and developed for hard materials (such as bauxite, alumina rock, etc.) A mining machine with a drum cutting mechanism for mining such as seams. This kind of mining machine not only cuts and breaks hard materials, but also spirally loads the materials into the conveyor at the same time, and is transported by the conveyor to form continuous material mining. [0003] With the gradual application of the drum-type cutting mechanism in the mining of bauxite layers, the characteristics of the original mineral material such as hardne...

AI Technical Summary

Problems solved by technology

[0003] With the gradual application of the drum-type cutting mechanism in the mining of bauxite layers, the characteristics of the original mineral material such as hardness, high density, and strong abrasiveness have gradually become prominent. The matching of cutting force and other parameters is strictly required, but due to the changing mining conditions during the mining process, problems such as wear and tear are prominent

Although the quality of cutting teeth has been optimized through experiments, the problem of too fast consumption of single cutting teeth is still not well solved, or although it has been solved to a certain extent, the cost performance of input and output is not high
