摘要： 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.

摘要： Disclosed is a reciprocating impact bevel tooth discharging shovel of a reciprocating impact mining machine, which includes a reciprocating impact box and a reciprocating impact bevel tooth discharging shovel (1). The reciprocating impact box includes a reciprocating impact box body (3), a reciprocating impact power element, and a reciprocating impact guide element (2). One end or both ends of the reciprocating impact guide element (2) extend out of the reciprocating impact box body (3). The reciprocating impact bevel tooth discharging shovel (1) includes a main tooth seat (5), main impact teeth (4), a lateral discharging tooth wing plate (6), and lateral discharging bevel teeth (7). The impacted materials are discharged from a gap which is formed by the lateral discharging bevel teeth (7) towering over the lateral discharging tooth wing plate (6), which reduces resistance of the materials to the reciprocating impact bevel tooth discharging shovel (1).
