Description

Technical Field

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. Mines include coal mines, metal mines, non-metallic mines, building materials mines, chemical mines, etc. In order to improve the safety of coal mining, a drilling test is required with a drilling machine before mining the relevant coal seams to determine whether the relevant requirements are met. At present, drilling in mines is mainly carried out by manual handheld drills, which can only be drilled in the horizontal or vertical direction. The drilling stability is poor, and it is impossible to drill at an inclined angle. In addition, dust and debris can be scattered during the drilling process, and workers are prone to inhaling dust into their lungs, affecting their health.

[0003] Publication No. CN116104425B discloses a drilling machine for mining. By setting a rotating assembly to cooperate with a control panel, the drilling angle of the drilling machine and the drill rod can be conveniently adjusted, and the stability during drilling can be effectively improved. By setting a dustproof mechanism composed of a fixed cylinder, a sealing plate, a positioning assembly, and an adjustment assembly to cooperate with the control panel, the debris and dust generated during drilling can be sealed and protected, effectively preventing the dust from flying around, solving the problem that the existing drilling machine can only drill in the horizontal or vertical direction, has poor stability during drilling, cannot drill at an inclined angle, and dust and debris are scattered around during drilling, affecting health. However, the patent still has the following problems in actual use:

[0004] Although the mining drilling machine can seal and protect the debris and dust generated during drilling by setting up a dustproof mechanism composed of a fixed cylinder, a sealing plate, a positioning assembly, and an adjustment assembly, which cooperates with the control panel and effectively prevents the dust from flying around, severe vibrations will occur during drilling. Not only is the base not reinforced, resulting in the base offset, affecting the accuracy of the drilling position, but there is also a certain gap between the fixed cylinder and the mine wall, causing the dust and debris generated by drilling to overflow from the gap, thereby affecting the dustproof effect of the dustproof mechanism.

[0005] Therefore, a drilling device for mining is proposed to solve the above-mentioned problems. Summary of the invention

At the same time, before drilling, the first rotating support 203 is used to rotate the stabilizing support rod 205 and the triangular support block 207 to the ground, and the first bevel gear transmission assembly 209 and the adjusting threaded rod 210 are driven to rotate by rotating the adjusting knob 208, so that the adjusting threaded sleeve 211 moves and the adjusting rotating rod 212 is driven to rotate, and the angle of the triangular support block 207 is adjusted, so that the triangular support block 207 can be sunk into the soil, thereby improving the stability of the entire stabilizing adjustment mechanism 2 and avoiding the mobile frame 20 from being shaken due to severe vibration during the drilling operation. 1 movement, thereby affecting the accuracy of the drilling position, by starting the lifting motor 216 to drive the lifting rotating rod 217 and the second bevel gear transmission assembly 218 to rotate, the second bevel gear transmission assembly 218 drives the lifting threaded rod 219 to rotate, and the lifting threaded sleeve 220 drives the lifting limit plate 221 to move up and down, so as to adjust the height of the drilling hole, by driving the rotating motor 223 to drive the rotating worm 224 to rotate, by utilizing the meshing connection between the rotating worm 224 and the rotating worm wheel 225, the rotating worm wheel 225 drives the rotating connecting shaft 226 and the drilling bracket 101 to rotate, so as to adjust the drilling angle, and facilitate drilling at different positions of the mine.

[0044] Secondly, the telescopic motor 105 is used to drive the telescopic threaded rod 106 to rotate, so that the telescopic threaded bracket 107 drives the telescopic sliding rod 108 and the telescopic rotating disk 109 to move, and the drilling motor 110 is started to drive the drilling driving gear 111 and the drilling rotating disk 112 to rotate. According to the drilling of different depths, the second mounting bracket 120 can be pulled outward, and under the action of the mounting rotating rod 115, the mounting sliding sleeve 116 drives the mounting limit block 117 to squeeze the mounting spring 118, and drives the mounting cover 122 and the mounting latch 123 to move relative to each other.

Since the dust bag 131 is made of a breathable material, air circulation can be achieved and dust overflow can be prevented, thereby achieving the effect of dust accumulation. The dust enters the dust bag 131 through the through hole 130 on one side of the dust cover 129 for collection. At the same time, opening the cleaning plug 132 can clean up the debris and dust. The rubber sealing ring 134 and the connecting spring 127 can activate the buffering effect, thereby facilitating the safety protection of the dust cover 129 and preventing severe vibration during drilling, which would cause damage to the dust cover 129.
