[0001] The present invention belongs to the technical field of mine geological development, and particularly relates to a drilling device for mine geological development and a using method thereof. Background Art

[0002] Mine geology refers to all geological work carried out within the scope of a proposed or existing mine after the deposit has been proven to have industrial value through geological exploration, including the development planning and exploration of the mining area, etc. To ensure the smooth progress of the mine's capital construction and normal production, mine development exploration requires continuous exploration of the deposit during the mine's capital construction and production processes, so as to use prospecting projects such as mine tunnels to provide more accurate and reliable geological data for mine construction, mining production, and the discovery of concealed ore bodies and the expansion of ore deposit reserves.

[0003] During the process of mine geological development, drilling operations are an extremely important link. Through drilling, key information such as underground geological structures and ore distributions can be obtained, providing a basis for formulating the mining plan of the mine. At the same time, it is also the basis for operations such as blasting and ventilation during the mining process. However, in the later use of existing drilling devices for mine geological development, the mine geological conditions are complex, and there are significant differences in the hardness and structure of underground rocks. The strong vibrations generated during drilling will cause a large impact on the equipment, not only affecting the service life of the equipment, but also possibly causing the drilling position to shift, affecting the drilling quality, and making it difficult to perform precise operations in different terrains and working environments.

A transmission column 9 is provided on the top of the transmission plate 6. The transmission column 9 penetrates the shock-absorbing frame 1. The top of the transmission column 9 is connected to a support plate 11. The top of the support plate 11 is connected to the drilling mechanism.

[0018] The drilling mechanism includes a servo motor 20, a rotary motor 25 and a fixed frame 19. A lead screw 21 is provided at the output end of the servo motor 20. The lead screw 21 is located inside the fixed frame 19. A lifting plate 22 is connected to the lead screw 21 by threads. Connecting rods 23 are provided on both sides of the lifting plate 22. The side parts of the connecting rods 23 are slidably connected to the inner wall of the fixed frame 19. An installation frame 24 is provided at the bottom of the connecting rod 23. The rotary motor 25 is installed inside the installation frame 24. The output end of the rotary motor 25 is connected to a drill rod 26. The drill rod 26 passes through the installation frame 24. A drill bit 27 is installed at the bottom of the drill rod 26.

[0019] Support sliding cylinders 28 are provided on both sides of the fixed frame 19. Connecting plates 30 are provided on both sides of the installation frame 24. A long sliding support rod 29 is fixedly connected to the connecting plate 30. The long sliding support rod 29 is slidably connected inside the support sliding cylinder 28. A scale groove 31 is provided on the long sliding support rod 29.

[0020] A support frame 16 is provided at the top of the support plate 11. A sliding column 17 is provided on the support frame 16. A sliding seat 18 is slidably connected to the sliding columns 17 on both sides. The sliding seat 18 is fixedly connected to the fixed frame 19.

[0021] A fixed seat 14 is further provided between the two support plates 11. An electric push rod 15 is installed above the fixed seat 14. The movable end of the electric push rod 15 is fixedly connected to the sliding seat 18.

[0022] A base plate 2 is provided on the side of the shock-absorbing frame 1. A fixing hole 3 is provided on the base plate 2. It is fixed to the ground by passing an anchor nail 4 through the fixing hole 3.
