Description

Technical Field

[0002] Mineral resources are important resources for human society. For example, coal mines are one of the important energy sources. Mining mineral resources requires the use of drilling rigs. Drilling rigs are mechanical equipment that drives drilling tools to obtain physical geological data during exploration or mineral resource development. There are two types of mining drill rigs: one is a vertical-axis lightweight drill rig, and the other is a pneumatic anchor drill rig.

[0003] Based on the above, the current mining drill rigs have a simple structure and a single function.

The disassembly and assembly structure 3 also includes a magnet 3026, a sliding support hole 3027 and a locking plug block 3028. Magnets 3026 are provided at both ends of the movable groove 3022, and sliding support holes 3027 are opened on the magnet 3026. The magnet 3026 is slidably installed on the outer side of the fixed cross bar 3024 through the sliding support hole 3027.

During mining, the cross slider 4021 can be pushed to move by starting the second cylinder 402, so that the cross slider 4021 drives the protective cover 403 to stick to the wall through the connecting vertical plate 4032, thereby avoiding the collapse of gravel during drilling.

[0054] A mining method with adjustable dust reduction: first, the second cylinder 402 is started to push the cross slider 4021 to move, so that the cross slider 4021 drives the protective cover 403 to stick to the wall through the connecting vertical plate 4032, so as to avoid the collapse of broken stones during drilling, which not only reduces the potential safety hazard, but also reduces the occurrence of dust. Then, the mineral resources are mined. Dust is inevitable during mining. Therefore, the water in the water tank 201 is transported through the bellows 2021 by starting the water pump 202, and finally sprayed out through the atomizing nozzle 2022, so as to deal with the dust generated during mining. After a period of mining, the drill bit is worn. At this time, the electromagnetic block 3023 is started to drive the magnet 3026 to move under the principle of opposite poles attracting each other, and then The magnet 3026 moves on the outside of the fixed cross bar 3024, so that the magnet 3026 drives the locking plug 3028 to disengage from the locking slot 3033, and then the worn drill bit can be disassembled. During installation, it is only necessary to insert the insertion slot 3032 on the rear side of the drill bit and the connecting block 3021 into each other, and then close the electromagnetic block 3023. Because the magnet 3026 squeezes the reset spring 3025 when moving on the outside of the fixed cross bar 3024, the reset spring 3025 produces elastic deformation, thereby pushing the magnet 3026 to move, so that the magnet 3026 drives the locking plug 3028 to reset and insert it into the locking slot 3033, thereby completing the installation, abandoning the complicated replacement method, reducing the downtime of the machinery, and improving the mining efficiency of mineral resources.
