Coal mining roadheader

Abstract

The invention relates to the technical field of energy mining, and discloses a coal mining roadheader. The coal mining roadheader comprises a main frame and a shell, wherein a main rod is fixedly installed in the middle of the main frame, and a telescopic rod is movably connected to the right side wall of the main rod in a sleeving mode. According to the coal mining roadheader, through the matching use of a first linkage part and a second linkage part, in the process of equipment operation, different linkage rods are selected for working according to different rock stratums, when the stratum is hard, a driving device is adopted to push the first linkage rod to move to the left side to drive the second linkage part to move, and thus an auxiliary drill bit connected to the second linkage part is driven to work; and when the stratum is soft, a driving part is utilized to drive the second linkage rod to work, thus a drill bit connected to the first linkage rod is driven to work, differentdrill bits can be effectively and reasonably selected according to different stratums, the wear of the equipment is effectively lowered, meanwhile the working efficiency of the equipment is also improved, and the time for replacing the drill bits is shortened.

Description

technical field [0001] The invention relates to the technical field of energy mining, in particular to a coal mining roadheader. Background technique [0002] Tunneling machine is a kind of comprehensive equipment that performs continuous operation by mechanically breaking rocks, removing slag and supporting. According to the cutting process of the tunneling machine on the working face, it is divided into full-section tunneling machine and partial section tunneling machine. It is mainly composed of walking mechanism, It is composed of working organization, shipping organization and reprinting organization. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good lane quality, but the cost is high, the structure is complicated, and the loss is also large. [0003] Most of the cutting heads of the existing roadheaders adopt an inte...

It has the advantages of safety, high efficiency and good lane quality, but the cost is high, the structure is complicated, and the loss is also large

[0003] Most of the cutting heads of the existing roadheaders adopt an integrated design. After working for a long time, the wear and tear is serious, and the cost of replacing the equipment is high. The cutting heads also need to choose different cutting heads according to different degrees of rock formations, resulting in equipment failure. It is a waste of time when replacing parts. When encountering many different rock formations, various cutting heads are required to work. Frequent replacement of cutting heads will seriously affect the working efficiency of the equipment. Therefore, this application introduces a coal mine mining roadheader.
