Anchor rod recycling device

Abstract

The invention discloses an anchor rod recycling device. The anchor rod recycling device comprises an anchor rod recycling device body, wherein a coring bit is arranged on the outer surface of one end of the anchor rod recycling device body, a large-diameter thin-wall drill spiral drill rod is arranged on the outer surface of one side of the coring bit, a core catcher is arranged on the outer surface of one side of the large-diameter thin-wall drill spiral drill rod, a connector is arranged on the outer surface of the other end of the anchor rod recycling device body, the coring bit comprises a bit body, a hard alloy tool bit and a wear-resistant ring, the hard alloy tool bit is located on the outer surface of one end of the bit body, and the wear-resistant ring is located in the middle of the bit body. According to the anchor rod recycling device, the anchor rod recycling problem is solved, basic guarantee is provided for safe and efficient stoping work, the labor intensity of miners is reduced, the efficiency is improved, the safety of the miners is guaranteed, and the anchor rod recycling device has the advantages of the simple structure and convenience in operation and has good use prospects.

Description

technical field [0001] The invention relates to the technical field of a bolt recovery device used in an underground bolter drilling vehicle in a coal mine, in particular to a bolt recovery device. Background technique [0002] The support technology used in mine roadways generally requires the use of spiral bolts as reinforcement materials, but coal mines often mine the roadways during the production process, and it is difficult to take out the bolts used for reinforcement, which can easily lead to accidents: [0003] 1. The remaining reinforced bolt will damage the coal cutter tool, and at the same time, if the spark generated after the collision between the bolt and the coal cutter meets the local accumulated gas, it will easily cause a gas explosion accident and bring serious safety hazards to underground production; [0004] 2. If the anchor bolts entering the coal flow system cannot be taken out in time, it may cause accidents in the transportation machinery, and may e...

AI Technical Summary

Problems solved by technology

[0002] The support technology used in mine roadways generally requires the use of spiral bolts as reinforcement materials, but coal mines often mine the roadways during the production process, and it is difficult to take out the bolts used for reinforcement, which can easily lead to accidents:

[0003] 1. The remaining reinforced bolt will damage the coal cutter tool, and at the same time, if the spark generated after the collision between the bolt and the coal cutter meets the local accumulated gas, it will easily cause a gas explosion accident and bring serious safety hazards to underground production;

[0004] 2. If the anchor bolts entering the coal flow system cannot be taken out in time, it may cause accidents in the transportation machinery, and may even lead to serious consequences of tearing the tape of the belt conveyor

In the production process, the anchor rod of the coal flow system is often taken out by stopping the scraper conveyor, which will reduce the operating rate of the equipment on the working face, and at the same time, it takes manpower and time to remove the anchor rod wound on the coal machine drum Rods, this way of handling anchor rods seriously affects the production of the working face

[0005] At present, in the mining process of the fully mechanized mining face, the general process for taking out the bolt with the wrong knife at the end (tail) is: when the shearer is wrongly knifed, the coal body in the triangular area will be arched and loosened, and then the bolt will be taken out, but this method Backward, difficult to master, there are major safety hazards, safety accidents and electromechanical accidents occur frequently
