Mining machine with rocker arm provided with coal-passing space

Abstract

The invention provides a mining machine with a rocker arm provided with coal-passing space, which comprises a machine body and a walking portion, and is characterized in that the mining machine with a rocker arm provided with coal-passing space also comprises a rocker arm, and cutting heads; the walking portion is disposed at the lower part of the machine body; the cutting heads are disposed at two ends of the machine body; the rocker arm is a rhomboid rocker arm or a single rocker arm; one end of the rocker arm is connected with the machine body, and the other end of the rocker arm is connected with the cutting heads; the rocker arm arches upwards to form the coal-passing space; the rocker arm is provided with the coal-passing space, which well solves the problem that coal falling by impact of a cutting head near a machine body of a reciprocating impact mining machine can not be conveyed out due to no coal-passing space between a straight rocker arm and a scraper conveyer, gives full play to advantages of high coal mining rate, high efficiency, energy saving, and environmental protection for reciprocating impact mining machines.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a mining machine with a rocker arm provided with a space for passing through coal, which is suitable for the mining field. Background technique [0002] The currently widely used mine mining equipment is the drum excavator. Its working principle is milling-type blanking. Due to the disadvantages of large dust, low lump rate and high power consumption in the milling-type blanking method, the forward mining and backward coal mining of the drum excavator are carried out through The spiral groove of the drum rotates the coal to the scraper, so its rocker arm is straight and does not require space for passing coal. Recently, a reciprocating impact excavator has been developed. The reciprocating impact excavator has high coal mining rate, high efficiency and energy saving. However, because the mining head of the reciprocating impact excavator has no coal discharge spiral groove, there is not...

AI Technical Summary

Problems solved by technology

However, because the mining head of the reciprocating impact mining machine has no coal discharge spiral groove, there is not enough space for passing coal between the rocker arm and the scraper machine, so the coal mined by the mining head close to the fuselage cannot be transported out. When the coal particle size is large, it is difficult to load the material, and the advantages and comprehensive performance of the mining head close to the fuselage of the reciprocating impact excavator cannot be brought into play.
