Digging and shovel impacting guide device of blocked coal shoveling machine

Abstract

The invention relates to the field of mine digging and particularly relates to a digging and shovel impacting guide device of a blocked coal shoveling machine. The device comprises a fixing base and a connecting flange; the device further comprises guide ring fixing plates, an anti-rotating bolt and at least more than two guide rings; an upper guide ring fixing plate and a lower guide ring fixing plate are mounted on the two sides of a digging and shovel impacting guide rod; the guide rings are fixedly arranged between the upper guide ring fixing plate and the lower guide ring fixing plate; and one end of the anti-rotating bolt penetrates through the center of the digging and shovel impacting guide rod. According to the digging and shovel impacting guide device of the blocked coal shoveling machine, the stress of digging and shovel impacting of the blocked coal shoveling machine is uniform, the vibration is small, the work is stable, the operation is simple, the utilization is flexible, the service life is long and the digging and shovel impacting guide device is easy to realize; and the combined efficiency of mine production is improved.

Description

technical field [0001] The invention relates to the field of mining, in particular to a guide device for mining and shovelling of a block coal shovel. Background technique [0002] The most widely used mining equipment at present is the drum shearer. Its working principle is milling-type blanking, which determines that the drum shearer mainly has the following defects in the use process: (1) the block rate is low; (2) there is a lot of dust, which pollutes the environment; (3) the cutting part The material under milling is relatively broken, the power consumption is large, there is a lot of waste of resources, and the cost is high. [0003] The invention with the patent number 200910309903.7 provides a coal mining method and a coal mining equipment for implementing the method. The coal mining head of the equipment includes a plow plate, and the distance between the blanking teeth at the front end of the plow plate and the front end of the wedge body is 300- 800mm, the blan...

Problems solved by technology

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 materials under milling are relatively broken, the power consumption is large, there is a lot of waste of resources, and the cost is high

However, the working principle of the punching block shearer is punching. Compared with the milling principle of the drum shearer, the force is uneven and the vibration is large during the working process. It is easy to deviate in the middle, and the deviation of the coal mining head increases the coal mining resistance, which reduces the coal mining efficiency and reduces the service life of the equipment
