Problems solved by technology

[0003] From the working principle and process of the mining machine, it can be known that the impact mining machine impacts the coal falling part during the working process. While impacting the coal wall, it also impacts the rocker arm and the fuselage, resulting in loosening of the connecting parts of the mining machine. The fatigue damage of the connecting pin will increase the failure rate, cause impact on the traction part, damage the drive and travel gears, and even cause damage to the traction motor, motor, and fracture of the rack.
[0004] Although the drum excavator is a circular motion of the drum, the picks mill the coal wall, but due to the distance between the picks, the picks will also produce certain impact and vibration when they touch the coal seam, especially when the coal seam is hard. Vibration is especially obvious, and these impact vibrations will also cause great harm to the mining machine, increase the failure rate of the mining machine, shorten the service life of the mining machine, and reduce the working efficiency of the mining machine
[0005] In order to solve the problem of impact vibration, various methods of adding buffer parts have appeared. However, due to the special technological limitations of mining machines, the buffer method that only adds buffer parts without restricting the buffering direction is likely to cause twisting and shearing of the fuselage, and even The twisting and shearing of the track caused many mining failures and damage to the fuselage, reducing production efficiency

Abstract

The invention relates to a buffering guide method by reciprocating impact reactive force and a vibration isolation mining machine. The vibration isolation mining machine comprises a lifting part, a reciprocating impact part, a machine body and a traveling part, wherein a buffering device is arranged on the lifting part or between the lifting part and the machine body or between the lifting part and the reciprocating impact part; the impact reactive force is applied on a buffering supporting piece and a fixed supporting piece or a buffering guide sleeve and a buffering guide piece; the buffering piece is deformed to absorb the impact reactive force; a direction guide piece controls a buffering direction to be reciprocating linear buffering, so that non-directional swinging of the buffering piece is prevented, and the buffering piece is prevented from being separated from the lifting part or the machine body; and impact vibration produced by a cutting stop part can be isolated; impact on a traction part and the machine body is reduced; looseness of connection fixing pieces is prevented; fatigue damage to the connection pieces is avoided; the fault rate of the mining machine is reduced; and the working efficiency of the mining machine is improved.

Description

technical field [0001] The invention belongs to the field of excavation, and in particular relates to a method for buffering and guiding reciprocating impact reaction force and a vibration-isolation mining machine. Background technique [0002] At present, the mining machine can be divided into two forms according to the working principle, one is the drum mining machine, and the other is the impact mining machine. The drum circumference of the drum excavator is provided with picks, and the drum rotates to drive the picks to cut the coal wall to realize coal mining; the impact type excavator relies on the reciprocating impact of the shovel impacting the coal drop part on the coal wall to achieve coal drop. [0003] From the working principle and process of the mining machine, it can be known that the impact mining machine impacts the coal falling part during the working process. While impacting the coal wall, it also impacts the rocker arm and the fuselage, resulting in loose...
