Punch-cutting mining method and punch-cutting mining machine implementing method

Abstract

The invention belongs to the machinery field and especially relates to a punch-cutting mining method suitable for the mining field and a punch-cutting mining machine implementing the method. According to the method, a machine body, a walking part, a reciprocating impact part and the like are arranged; a lifting device is arranged or not arranged on the machine body; a dynamic impacting member is disposed on an impact driving device; a guiding device is provided with an impact guiding element; two ends of the impact guiding element are both equipped with an impactor or one end is provided with an impactor and the other end is provided with a counterweight; and the machine body supports the impactor to shock dropping materials back and forth. The equipment comprises the machine body, the walking part, the reciprocating impact part and the like. The reciprocating impact part comprises the dynamic impacting member, the impact driving device, the impactor and the like. The impact driving device comprises the dynamic impacting member. The guiding device comprises the impact guiding element; the dynamic impacting member drives the impactor to shock the coal wall or rock faces for blanking materials; the lifting device is arranged or not arranged on the machine body; the walking part is disposed on the lower part of the machine body and drives the machine body to walk so as to blank materials during walking and walk back to blank materials without turning the machine body.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a punching excavation method suitable for the mining field and a punching mining machine for implementing the method. Background technique [0002] The currently widely used mining equipment is the drum shearer, and its working principle is milling type blanking, which determines that the crushing of this mining method is relatively large, especially in the state of compressive stress, which consumes a lot of energy and reduces production. The crushing process also produces a large amount of dust, which causes problems such as bad mining environment and potential safety hazards, and greatly reduces the economic value and use value of the excavated materials. [0003] With the development of mining technology, a new mining equipment is urgently needed because: [0004] Lump coal is a necessity for the development of the national economy; [0005] The economic value of lump coal is more ...

Problems solved by technology

[0013] The invention with the patent number 201110157890.3 discloses a high-efficiency block coal shoveler. In this equipment, a shovel head is provided at one end of the impact stroke guide mechanism and the other end is not provided with a shovel head, so that the shovel head is seriously separated from the impact stroke guide mechanism, and the sliding friction force Concentrated on the part of the impact stroke guide mechanism, due to overheating, the shock stroke guide mechanism and the guide sleeve will be glued or even seized in a short period of time, resulting in high friction resistance and high power consumption, making the equipment unable to operate normally; the shovel head is arranged in one direction, and the reverse adopts However, due to the small underground space, the general mining roadway is less than 6 meters wide, and the length of the fuselage is at least 8 meters. The problem of turning the fuselage is difficult to solve, and even if the fuselage can be turned, it will It consumes a lot of manpower, material resources and time, so the whole machine must be returned to the corresponding position before coal mining can continue
