[0002] Coal mine borehole sampling is typically used to determine coal quality characteristics and industrial value. By analyzing the chemical composition, physical properties, and technological performance of coal samples, key indicators such as coal type, ash content, and calorific value are identified, providing a basis for assessing the economic value of coal resources and the direction of industrial utilization. After the excavation of coal seams in mines, borehole sampling is required to analyze the thickness of the coal seams and determine the subsequent mining value of the coal mine.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: Example 1: A coal geological detection device: including a drilling frame 1, traveling wheels 2, a counterweight platform 3, and a coal mine borehole sampling geological analysis detection unit. The traveling wheels 2 are located at the bottom of the drilling frame 1, the counterweight platform 3 is installed at the bottom inside the drilling frame 1, and the coal mine borehole sampling geological analysis detection unit is located at the top area of ​​the drilling frame 1 for sampling and detection of the inner wall of the coal mine.

[0018] The coal mine borehole sampling geological analysis and detection unit includes a borehole section, which includes a linear guide rail 4. The linear guide rail 4 is embedded in the top of the drilling frame 1. A positioning chamber 5 is set in the top area of ​​the linear guide rail 4. The positioning chamber 5 is installed on the top of the drilling frame 1. A moving plate 41 is installed on the moving end of the linear guide rail 4. A stabilizing frame 42 is installed on the top of the moving plate 41. A micro drill 43 is installed on one side of the stabilizing frame 42. A center platform 52 is installed on the side of the positioning chamber 5 near the micro drill 43. The rotating rod of the micro drill 43 passes through the center platform 52. A drill bit 44 is installed on the rotating rod of the micro drill 43. A through groove 53 is provided on the surface of the center platform 52.

[0019] The coal mine borehole sampling geological analysis and detection unit also includes a sampling section, which includes a support 51. The support 51 is installed on one side of the positioning chamber 5. A flip cover 6 is installed on one side of the support 51 via an electric hinge. The surface of the flip cover 6 is provided with an arc-shaped groove 61. Two sets of arc-shaped guide rails 62 are installed on the inner wall of the arc-shaped groove 61. A slider 63 is installed on the moving end of the arc-shaped guide rail 62. A rake frame 64 is installed at the bottom of the slider 63. A high-temperature resistant liquid bladder 65 is installed at the bottom of the rake frame 64. Several sets of high-temperature resistant liquid bladders 65 are independently set. A hard brush layer 66 is installed on the bottom surface of the high-temperature resistant liquid bladder 65. The hard brush layer 66 is in active contact with the surface of the drill bit 44.

[0020] The coal mine borehole sampling geological analysis and detection unit also includes a collection section, which includes a limiting rod 7. The limiting rod 7 is installed on the side of the center platform 52 near the drill bit 44. A movable shell 71 is provided at the bottom of the drill bit 44. A through hole 72 is provided on the surface of the movable shell 71. The movable shell 71 is sleeved on the surface of the limiting rod 7 through the through hole 72. A straight toothed plate 73 is provided at the bottom of the movable shell 71. A collection hopper 8 is magnetically installed at the top of the movable shell 71. A bottom groove 54 is provided through the bottom of the positioning chamber 5. A micro motor 55 is installed inside the bottom groove 54. A transmission gear 56 is installed on the rotating end of the micro motor 55. The transmission gear 56 meshes with the straight toothed plate 73.

[0021] In this embodiment, the flip cover 6 can be rotated and closed towards the drill bit 44 by driving the electric hinge. When the flip cover 6 is closed on the surface of the drill bit 44, the high-temperature resistant liquid bladder 65 and the hard brush layer 66 on the surface of the rake frame 64 will adhere to the groove area on the surface of the drill bit 44. After the high-temperature resistant liquid bladder 65 is squeezed, the hard brush layer 66 covering the bottom surface of the high-temperature resistant liquid bladder 65 will fully adhere to the groove on the surface of the drill bit 44, thereby facilitating the effective collection of coal seam samples in the required area in the groove on the surface of the drill bit 44. Subsequently, the rake frame 64 is driven to reciprocate by driving the arc-shaped guide rail 62 to ensure the full collection of coal seam samples.

[0022] Example 2: Based on Embodiment 1, this embodiment considers that if the drilling frame 1 cannot be restricted in a targeted manner during the drilling and sampling process, the drill rod of the micro drill 43 will vibrate excessively during the drilling process, which will easily lead to accelerated wear of the drill bit 44 and the drill rod will be at risk of breakage. Therefore, this embodiment is equipped with a drilling and sampling anti-vibration unit to reduce the impact of the above problems on drilling and sampling. The counterweight platform area 3 is equipped with a drilling sampling anti-shake unit.

[0023] The drilling sampling anti-shake unit includes a movable plate 32, a counterweight platform 3 with a storage cavity 31 on its surface, the movable plate 32 is slidably installed inside the storage cavity 31, and a locking screw 34 is installed on the outside of the storage cavity 31 to lock the position of the movable plate 32.

[0024] The movable board 32 is set in two sets, and the bottom of the movable board 32 is equipped with an anti-slip rubber platform 33.

[0025] In this embodiment, the locking screw 34 is loosened, and then the movable plate 32 is taken out from the storage cavity 31. The movable plate 32 then presses the anti-slip rubber platform 33 against the ground, thereby restricting the movement of the drilling frame 1. Then the locking screw 34 is tightened again, thereby locking the drilling frame 1 before the drill bit 44 takes samples, ensuring stable drilling and sampling. Then the drill bit 44 is driven by the micro drill 43 to perform the drilling and sampling steps, ensuring normal sampling inside the mine.

[0026] Working principle: The operator moves the drilling frame 1 using the walking wheels 2. Once the drilling frame 1 is in place, the linear guide 4 can be driven to move the moving plate 41 and the stabilizing frame 42 toward the inner wall of the mine. At this time, the locking screw 34 can be loosened, and then the moving plate 32 can be taken out of the storage cavity 31. The moving plate 32 then presses the anti-slip rubber platform 33 against the ground, thereby restricting the movement of the drilling frame 1. The locking screw 34 is then tightened again to lock the drilling frame 1 before the drill bit 44 takes samples, ensuring stable drilling and sampling. Then, the micro drill 43 drives the drill bit 44 to perform the drilling and sampling steps, ensuring normal sampling inside the mine. After the drill bit 44 has finished sampling, the drill bit 44 can be slowly removed from the borehole by driving the linear guide rail 4 again. At this time, the drill bit 44 is stopped by driving the micro drill 43, and then the collection of the sampled components on the surface of the drill bit 44 begins. When the drill bit 44 is slowly withdrawing from the borehole, the flip cover 6 can be rotated and closed towards the drill bit 44 by driving the electric hinge. When the flip cover 6 is closed on the surface of the drill bit 44, the high-temperature resistant liquid bladder 65 and the hard brush layer 66 on the surface of the rake frame 64 will adhere to the groove area on the surface of the drill bit 44. After the high-temperature resistant liquid bladder 65 is squeezed, the hard brush layer 66 covering the bottom surface of the high-temperature resistant liquid bladder 65 will fully adhere to the groove on the surface of the drill bit 44, thereby facilitating the effective collection of coal seam samples in the required area in the groove on the surface of the drill bit 44. Then, the rake frame 64 is driven to reciprocate by driving the arc guide rail 62 to ensure the full collection of coal seam samples. After the drill bit 44 is completely withdrawn, the micro motor 55 can be driven first. The micro motor 55 drives the transmission gear 56 to rotate. The transmission gear 56, through meshing transmission, causes the movable shell 71 to move and unfold toward the position of the drill bit 44. When the movable shell 71 reaches the position close to the drill bit 44, the micro motor 55 is stopped. At this time, the collection hopper 8 at the top of the movable shell 71 can cover the bottom of the drill bit 44 when the drill bit 44 is withdrawn, preventing the sample taken from the surface of the drill bit 44 from falling in a scattered manner. Since the position of the drill bit 44 is fixed, the coal seam sample swept back and forth from the surface of the drill bit 44 can be evenly scattered in the limited area inside the collection hopper 8, which makes it easier for the exploration personnel to collect samples.
