Problems solved by technology
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.

The invention relates to the technical field of energy exploitation, and discloses a coal mining roadheader, which includes a main frame and a casing, a main rod is fixedly installed in the middle of the main frame, and a telescopic rod is movably socketed on the right side wall of the main rod . In the present invention, through the cooperation of the first linkage and the second linkage, during the operation of the equipment, different linkage rods are selected to work according to the different rock formations. When the rock formation is relatively hard, the driving device is used to push the second linkage A linkage rod moves to the left, so that it drives the second linkage to move, and then drives the auxiliary drill bit connected to the second linkage to work. When the rock formation is soft, use the drive to drive the second linkage to work , and then drives the drill bit connected to the first linkage to work. This device can effectively select different drill bits reasonably according to different rock formations, effectively reducing the wear of the equipment, and at the same time improving the working efficiency of the equipment and reducing the equipment cost. Time to change drill bits.
Description
technical field [0001] The invention relates to the technical field of energy mining, in particular to a coal mining roadheader. Background technique [0002] The roadheader is a comprehensive equipment that uses mechanical crushing of rocks, ballast removal and support for continuous operation. According to the cutting process of the roadheader on the working surface, it is divided into full-section roadheaders and partial-section roadheaders. It consists of working organization, shipping organization and transshipment organization. As the traveling mechanism moves forward, 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 quality of lanes, but the cost is high, the structure is complex, and the loss is also large. [0003] Most of the cutting heads of the existing roadheaders adopt an integrated design. After long-term work, the wear and tear is serious, an...
