Abstract

A rolling friction or suspension friction impact mining method and a wear-resistant impact mining machine using said method. The mining machine comprises a reciprocating impact part (3). The reciprocating impact part comprises an impact drive device (4), a rolling reciprocating device, and an impact head (6). The rolling reciprocating device comprises a rubbing body (38), a rubbing body support (39), an impact guiding element (5.1), and a position-limiting mechanism. The rubbing body (5.3) are disposed between the robbing body support (39) and the impact guiding element (5.1), and inside of the position-limiting mechanism to form rolling guiding. The impact drive device is disposed with a damage-prevention mechanism, a rotary power buffer device, and a structural buffer device, such that the impact head reciprocatingly move and have rolling or suspending friction under the support of the impact guiding element, thereby preventing the damage-prevention force to damage a power drive device and a rolling channel guiding device, and preventing the impact vibration caused by the reciprocating impact part to affect the machine body and other parts. The overall stability is therefore enhanced, and the service life is extended.

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention belongs to the mechanical field, and is especially applicable to a rolling friction or suspension friction impact mining method in the mining field and a wear-resistant impact mining machine using said method.BACKGROUND OF THE INVENTION

[0002] Tunneling machines and coal mining machines are mainly applied to excavation of railways, bridges and culverts of roads and tunnels and mechanical mining of ore materials. Most mining machines broadly applied at present are drilling and milling cutting-type tunneling machines and rolling milling cutting-type mining machines and the working principle is to drill and cut or mill and cut in a rolling manner a coalbed or a rockbed through picks arranged on the outer surface at a front part of a cutting head. Since a relatively large rotating damage force is generated by the cutting head during drilling and milling or rolling milling and cutting, a relatively large twisting force will be gen...
