Bidirectional pounding and cutting excavating method and bidirectional pounding and cutting excavator for implementing same

Abstract

The method provided by the invention comprises the following steps: a machine body, a walking part, a lifting part, a reciprocating pounding part and the like are arranged; a pounding guide element and the like are arranged on a pounding guide device; pounding heads are arranged at two ends of the pounding guide element, so that a power pounding element drives the pounding guide element; the reciprocating pounding part is arranged on the lifting part; the lifting part is arranged on the machine body; and the walking part drives the machine body to move ahead and retreats so as not to turn the machine body to excavate and drop materials forward and backward. Equipment provided by the invention comprises the machine body, the walking part, the lifting part, the reciprocating pounding part and the like; the reciprocating pounding part comprises the pounding guide device, the pounding driving device and the like; the pounding heads are both arranged at two ends of the pounding guide element; the pounding driving device comprises the power pounding element and the like; the power pounding element drives the pounding guide element to move in a reciprocating mode; the pounding guide element drives the pounding heads to pound; the reciprocating pounding part is arranged on the lifting part; the lifting part is arranged on the machine body; the walking part drives the machine body to move ahead and retreat so as not to turn the machine body to excavate and drop materials forward and backward.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a method for two-way punching and mining applicable to the field of mining and a two-way punching mining machine for implementing the method. Background technique [0002] The currently widely used mining equipment is drum shearer and drill-washing roadheader, whose working principle is milling blanking, which determines that the crushing of this mining method is relatively large, especially in the state of compressive stress. A large amount of energy reduces the production efficiency and block rate. 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] (1) Lump coal is a necessity for the development of the na...

AI Technical Summary

Problems solved by technology

[0007] Based on the above requirements, there have been many ways to use lump minerals. For example, a high-efficiency block coal shovel is arranged in one direction of the coal mining head, and the fuselage must be turned when reverse coal mining. However, due to the small underground space, the general The mining roadway is less than 6 meters wide, and the length of the fuselage is at least 8 meters. Coal mining can be continued. Due to the heavy weight of the coal mining head, one end of the impact rod is too heavy and the other end is too light. During reciprocating impact, it is easy to cause the impact rod and the impact guide to be separated due to weight imbalance, reducing the impact. service life, increased power consumption
