[0001] The utility model relates to the technical field of underground coal mine geological survey, in particular to a coring device for mining geological survey. Background Art

[0002] During the mining process of underground coal mines, it is necessary to measure the geology of the coal mines. Through measurement, the distribution, thickness and other parameters of the coal seams can be known, which can provide corresponding data for subsequent coal mining. In the process of obtaining the above data, the coring device of mining geological measurement will be used. The coring device is a coring tool that uses a coring tool to extract large pieces of rock core from the underground of the mining area during the drilling process.

[0003] Traditional coring devices used in mining geological surveys need to maintain stability when moving them to coal mining areas to avoid inconvenience caused by displacement and tipping during coring. Therefore, we propose a coring device for mining geological surveys to address these issues. Utility Model Content

A large pulley 18 is movably provided at the middle position of the top of the fixed plate 15. Small pulleys 13 are provided at the front and rear ends of the large pulley 18, and the bottom end of the small pulley 13 is movably connected to the top of the fixed plate 15. A transmission belt 19 is movably provided on the outer side walls of the large pulley 18 and the small pulley 13. A threaded rod 14 is movably provided inside the small pulley 13. The inner side wall of the small pulley 13 is evenly provided with an internal thread. A threaded connection is formed between the small pulley 13 and the threaded rod 14, which pushes the threaded rod 14 into the soil in the coal mine area. There are two groups of threaded rods 14, and the two groups of threaded rods 14 are symmetrically distributed about the central axis of the fixed plate 15. The symmetrically distributed threaded rods 14 greatly increase the stability of the coring device.

[0024] Specifically, if Figure 1 and Figure 2 As shown, after the device is moved to the corresponding position in the coal mine area by the roller 12, the large pulley 18 is rotated, and the small pulleys 13 at both ends are driven to rotate through the transmission belt 19. The rotation of the small pulley 13 causes the threaded rod 14 connected to its internal thread to move downward and penetrate into the soil in the coal mine area, allowing the coring device to be stably placed on the coal mine area for work.

[0025] A rotating seat 16 is fixed on both sides of the top of the mounting seat 3. A rotating groove 17 is provided on the top of the rotating seat 16. The rotating groove 17 is provided at the bottom end of the inside of the horizontal plate 5. There are two sets of rotating seats 16 and rotating grooves 17. A sliding structure is formed between the rotating seat 16 and the rotating grooves 17, which has a better guiding effect on the mounting seat 3.

[0026] Specifically, if Figure 1 and Figure 2 As shown, the servo motor 4 rotates to drive the mounting base 3 to rotate, and the rotating bases 16 on both sides of the top of the mounting base 3 will rotate in the rotating groove 17 inside the horizontal plate 5, driving the mounting base 3 to rotate stably, thereby driving the drill rod corer 2 at the bottom end of the mounting base 3 to rotate stably to perform coring work.

[0027] Threaded rods 20 are movably provided at the front and rear ends of the interior of the movable seat 1, and a clamping ring 21 is movably provided on one side of the threaded rod 20, and a brush 24 is fixed to the inner side wall of the clamping ring 21, and a sliding rod 23 is fixed to the left side of the clamping ring 21, and a slide rail 22 is movably provided inside the slide rod 23, and one side of the slide rail 22 is fixed to the outer side wall of the movable seat 1, and two groups of clamping rings 21 are provided, and the clamping rings 21 are all arc-shaped, which makes the wiping of the drill rod corer 2 more fitting and has a better wiping effect. The cross section of the slide rod 23 is larger than the cross section of the slide rail 22, and a sliding structure is formed between the slide rod 23 and the slide rail 22, so that the clamping ring 21 can be stably adjusted;

[0028] Specifically, if Figure 3 and Figure 4 As shown, the distance between the two sets of clamping rings 21 is adjusted according to the width of the drill rod corer 2 used. During adjustment, the threaded rod 20 is rotated to push the clamping ring 21 inward by sliding the slide rod 23 on the outer wall of the slide rail 22. After the spacing inside the clamping ring 21 is adjusted to a spacing that matches the diameter of the drill rod corer 2, the brush 24 on the inner wall of the clamping ring 21 will brush and clean the outer wall of the drill rod corer 2 when the drill rod corer 2 is rotated and moved up and down to perform coring.

[0029] Working principle: When the present invention is in use, the core-taking device is moved to the corresponding position on the coal mine area by the rotation of the roller 12. After moving to the corresponding position, the large pulley 18 is rotated, and the small pulleys 13 at both ends are driven to rotate through the transmission belt 19. The rotation of the small pulley 13 causes the threaded rod 14 connected to the internal thread to move downward and penetrate into the soil of the coal mine area. After the core-taking device is stably placed, the large pulley 18 is rotated, and the small pulleys 13 at both ends are driven to rotate through the transmission belt 19. The rotation of the small pulley 13 causes the threaded rod 14 connected to the internal thread to move downward and penetrate into the soil of the coal mine area. The drill rod corer 2 moves downward and penetrates into the soil in the coal mine area. The drill rod corer 2 is taken out and installed at the bottom of the mounting base 3. The servo motor 4 is then started to drive the drill rod corer 2 to rotate. At the same time, the gear 11 is rotated so that the engagement between the gear 11 and the tooth block 9 causes the cross plate 5 to push the rotating drill rod corer 2 downward to move, so that the drill rod corer 2 penetrates into the stratum of the coal mine area for coring. After coring, the gear 11 is rotated in the opposite direction to drive the drill rod corer 2 to move upward. The brush 24 attached to the surface of the drill rod corer 2 will brush and clean the surface of the drill rod corer 2 to remove dust adhering to the surface.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
