Excavating and shoveling buffer transmission device of lump coal shovel

Abstract

The invention belongs to the fields of mineral extraction, mining tunneling and tunnel excavation, and particularly relates to an excavating and shoveling buffer transmission device of a lump coal shovel. The device comprises a driving gear, a driven gear and a gear mounting rack, wherein the driving gear and the driven gear form a clearance fit; the driven gear is connected with a power output shaft; and the clearance between the driving gear and the driven gear absorbs the amount of deformation during the work of the power output shaft. Thus, the vibration of the body of the device is prevented, so that the excavating and shoveling work is smooth, and the coal mining process is improved, thereby bringing great benefits to coal mine production.

Description

technical field [0001] The invention belongs to the fields of mining, mine excavation and tunnel excavation, and in particular relates to a mining shovel buffer transmission device for a block coal shovel. Background technique [0002] The currently widely used mine mining equipment is the drum shearer. Its working principle is milling type blanking, which determines that the drum shearer mainly has the following defects during use: (1) low lump material rate; (2) much dust, which pollutes the environment; (3) the cutting part The material under milling is relatively broken, the power consumption is relatively large, there is a lot of waste of resources, and the cost is high. Owing to there is above shortcoming, so this commonly adopted method is badly in need of improving or seeking new coal mining mode. [0003] With the rapid development of coal and rock mining technology, the research on a new coal mining method that makes full use of the compressive stress of coal far...

[0004] However, although the theory of coal mining technology has been demonstrated, and many methods have been put forward for this theory; however, many methods only put forward proposals for coal mining methods, without explaining or explaining from specific mechanisms such as technology, materials, and costs.
