Through geological exploration sampling, information such as the layered structure and characteristics of the coal mine geology can be accurately understood, which is of decisive significance for formulating a scientific and reasonable mining plan and ensuring mining efficiency and safety; traditional coal mine geological exploration sampling methods can either only obtain geological samples at a single depth, making it difficult to comprehensively reflect the complex layered conditions of the coal mine geology, or can sample multiple layers.

Detailed implementation manners

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail in combination with the embodiments and the drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in combination with the embodiments and the drawings, but the protection scope is not limited by this.

[0035] Refer to Figures 1 to 7 , in this embodiment, a geological exploration sampling device based on coal mine exploitation is proposed, which includes the vehicle body 1 of a crawler vehicle. One side of the top of the vehicle body 1 is rotatably connected with a rotating plate 2. One side of the top of the rotating plate 2 is fixedly connected with a support plate 5. A first cylinder 6 is fixedly connected below the support plate 5. The driving part of the first cylinder 6 is fixedly connected with a fixed box 3; under the driving action of the first cylinder 6, the fixed box 3 can be lifted and lowered. In order to keep the fixed box 3 stable during the lifting and lowering process, a first limiting rod 4 is fixedly connected to one side of the rotating plate 2, and the first limiting rod 4 is slidably connected with the fixed box 3, playing a guiding and limiting role in the movement of the fixed box 3.

[0036] Inside the fixed box 3, a first motor 12 is fixedly connected. At the driving end of the first motor 12, a first rotating shaft 7 is fixedly connected. At the bottom end of the first rotating shaft 7, a drill bit 11 is fixedly connected. At the bottom of the fixed box 3, a third threaded rod 17, a second threaded rod 16 and a first threaded rod 15 are rotatably connected, and the third threaded rod 17, the second threaded rod 16 and the first threaded rod 15 are arranged in sequence from one side of the first rotating shaft 7 towards the outer edge of the fixed box 3. A first sleeve 8 is threadedly connected to the third threaded rod 17, a second sleeve 9 is threadedly connected to the second threaded rod 16, and a third sleeve 10 is threadedly connected to the first threaded rod 15. And the first rotating shaft 7, the first sleeve 8, the second sleeve 9 and the third sleeve 10 are nested layer by layer from the inside out: that is, the inner diameter of the third sleeve 10 is larger than the outer diameter of the second sleeve 9, and the inner diameter of the second sleeve 9 is larger than the outer diameter of the first sleeve 8, so that the sleeves can be nested with each other when being stored or extended, saving space, and can penetrate to different depths in sequence during the sampling process without interfering with each other, which is beneficial to the stratified collection and differentiation of geological samples at different depths.

[0037] Collection grooves 24 are arranged inside the first sleeve 8, the second sleeve 9 and the third sleeve 10. The drill bit 11 at the bottom of the first rotating shaft 7 passes through the first sleeve 8, the second sleeve 9 and the third sleeve 10 respectively and is located at the lowermost end. The first motor 12 drives the first rotating shaft 7 to rotate, thereby causing the drill bit 11 to rotate and drill into the geological layer, and the diameter of the drill bit 11 is larger than the outer diameter of the third sleeve 10, ensuring that the drill bit 11 enters the geological layer prior to the three sleeves for preliminary drilling operations.

[0038] At both sides of the tops of the first sleeve 8, the second sleeve 9 and the third sleeve 10, air pumps 14 are fixedly connected. The air pipes of the air pumps 14 are communicated with the corresponding collection grooves 24, which is the key to realizing the suction of geological samples into the collection grooves 24. The air pumps 14 use the air pressure difference to collect the samples into the collection grooves 24, ensuring the effective realization of the sampling function.

[0039] At one side of the bottom of the fixed box 3, a second cylinder 13 is fixedly connected. At the driving end of the second cylinder 13, a protection box 18 is fixedly connected. Inside the protection box 18, a second motor 19 is fixedly connected. At the driving end of the second motor 19, a second rotating shaft 20 is fixedly connected. At the other end of the second rotating shaft 20, a first bevel gear 21 is fixedly connected. At the tops of the first threaded rod 15, the second threaded rod 16 and the third threaded rod 17, second bevel gears 22 are fixedly connected, and the second bevel gears 22 can be meshed with the first bevel gear 21. The second cylinder 13 can push the protection box 18 to move, so that the second motor 19 inside and the connected first bevel gear 21 reach the appropriate positions to be meshed with the second bevel gears 22 at the tops of the corresponding threaded rods, enabling the power of the second motor 19 to be transmitted to each threaded rod, thereby driving the sleeves threadedly connected thereto to move up and down.

[0040] Three second limiting rods 23 are fixedly connected to the bottom of the fixed box 3. The three second limiting rods 23 are respectively slidably connected to the first sleeve 8, the second sleeve 9 and the third sleeve 10, which play a role in restricting the rotation of the sleeves and guiding the linear lifting of the sleeves.

[0041] Two mutually joined baffles 25 are provided at the bottom of each of the first sleeve 8, the second sleeve 9 and the third sleeve 10; the baffle 25 is semi-circular ring-shaped, and an annular structure with a through hole in the middle is formed after the two baffles 25 are mutually joined; the first rotating shaft 7 passes through the through hole for vertical movement; the outer edge of the baffle 25 is connected with a torsion spring 26; the other end of the torsion spring 26 is connected to the inner wall of the corresponding sleeve. During sampling, the elastic force of the torsion spring 26 is used to make the baffle 25 block the geological sample from entering the corresponding sleeve interior, preventing the geological sample from affecting the subsequent use of the sleeve. When the inner sleeve extends out, under the action of the driving force, the baffle 25 is knocked open to make the inner sleeve extend out. When the inner sleeve retracts, the baffle 25 resets under the action of the torsion spring 26.

[0042] The geological samples at different depths can be collected respectively through the three sleeves, which can more comprehensively and accurately reflect the layered structure and characteristics of the coal mine geology, provide detailed and reliable geological data basis for the subsequent coal mine mining operation, help to formulate a scientific and reasonable mining plan, and improve the mining efficiency.

[0043] A geological exploration sampling method based on coal mine mining provided by this embodiment adopts the above-mentioned geological exploration sampling device for coal mine mining, and specifically includes the following steps:

[0044] Step 1: When geological exploration sampling is required, first move the whole device to the sampling position through the vehicle body 1 of the crawler vehicle, and rotate the rotating plate 2 to finely adjust the angle of the rotating plate 2, and finally determine the drilling point;

[0045] Step 2: Start the first cylinder 6 to drive the fixed box 3 to descend to a suitable height position, then start the first motor 12, the first motor 12 drives the first rotating shaft 7 to rotate, and the drill bit 11 at the bottom end of the first rotating shaft 7 rotates accordingly, and the drill bit 11 starts to drill into the coal mine geological layer; the function of the drill bit 11 is to loosen the geological layer for subsequent sampling work. When the drill bit 11 drills to a certain depth, turn off the first motor 12.

[0046] Step 3: Start the second cylinder 13. The second cylinder 13 pushes the protection box 18 to move. The second motor 19 in the protection box 18 drives the second rotating shaft 20 to rotate, so that the first bevel gear 21 on the second rotating shaft 20 meshes with the second bevel gear 22 at the top of the first threaded rod 15. After the first bevel gear 21 meshes with the second bevel gear 22 at the top of the first threaded rod 15, the rotation of the second motor 19 drives the first threaded rod 15 to rotate. Since the first threaded rod 15 is threadedly connected to the third sleeve 10, and the third sleeve 10 is slidably limited by the second limiting rod 23, the third sleeve 10 can move downward along the first threaded rod 15 and enter the geological layer at the shallow position; then start the air pumps 14 on both sides at the top of the third sleeve 10. The air pumps 14 on both sides at the top of the third sleeve 10 are communicated with the collection groove 24 opened on the third sleeve 10 through air pipes, and under the action of the air pressure difference, the geological samples at the shallow position are sucked into the collection groove 24 inside the third sleeve 10, and under the action of the torsion spring 26 at the bottom of the third sleeve 10, the baffle 25 at the bottom of the third sleeve 10 blocks the geological samples from entering the inside of the third sleeve 10.

[0047] Step 4: After the sampling is completed, the second motor 19 rotates in the reverse direction to make the third sleeve 10 rise back to the initial position, and then turn off the air pumps 14 on the third sleeve 10 to collect the geological samples inside the collection groove 24 of the third sleeve 10.

[0048] Step 5: Start the second cylinder 13. The second cylinder 13 pushes the protection box 18 to move. The second motor 19 in the protection box 18 drives the second rotating shaft 20 to rotate, so that the first bevel gear 21 on the second rotating shaft 20 meshes with the second bevel gear 22 at the top of the second threaded rod 16. After the first bevel gear 21 meshes with the second bevel gear 22 at the top of the second threaded rod 16, the rotation of the second motor 19 drives the second threaded rod 16 to rotate. Since the second threaded rod 16 is threadedly connected to the second sleeve 9, the second sleeve 9 can move downward along the second threaded rod 16 to push open the baffle 25 at the bottom of the third sleeve 10 and enter the geological layer at the middle position; then start the air pumps 14 on both sides at the top of the second sleeve 9. The air pumps 14 on both sides at the top of the second sleeve 9 are communicated with the collection groove 24 opened on the second sleeve 9 through air pipes, and under the action of the air pressure difference, the geological samples at the middle position are sucked into the collection groove 24 inside the second sleeve 9, and under the action of the torsion spring 26 at the bottom of the second sleeve 9, the baffle 25 at the bottom of the second sleeve 9 blocks the geological samples from entering the inside of the second sleeve 9.

[0049] Step Six: After sampling is completed, the second motor 19 rotates in reverse to raise the second sleeve 9 back to its initial position. At this time, the baffle 25 at the bottom of the third sleeve 10 is reset under the action of the torsion spring 26 connected thereto; then, the air pump 14 on the second sleeve 9 is turned off, and the geological samples inside the collection tank 24 of the second sleeve 9 are collected.

[0050] Step Seven: Start the second cylinder 13. The second cylinder 13 pushes the protection box 18 to move. The second motor 19 in the protection box 18 drives the second rotating shaft 20 to rotate, thereby causing the first bevel gear 21 on the second rotating shaft 20 to mesh with the second bevel gear 22 at the top of the third threaded rod 17. After the first bevel gear 21 meshes with the second bevel gear 22 at the top of the third threaded rod 17, the rotation of the second motor 19 drives the third threaded rod 17 to rotate. Since the third threaded rod 17 is threadedly connected to the first sleeve 8, the first sleeve 8 can move downward along the third threaded rod 17 and push open the baffle 25 at the bottoms of the second sleeve 9 and the third sleeve 10 to enter the geological layer at a deep position; then, start the air pumps 14 on both sides at the top of the first sleeve 8. The air pumps 14 on both sides at the top of the first sleeve 8 communicate with the collection tank 24 opened on the first sleeve 8 through air pipes. Under the action of the air pressure difference, the geological samples at the deep position are sucked into the collection tank 24 inside the first sleeve 8, and under the action of the torsion spring 26 at the bottom of the first sleeve 8, the baffle 25 at the bottom of the first sleeve 8 blocks the geological samples from entering the inside of the first sleeve 8.

[0051] Step Eight: After sampling is completed, the second motor 19 rotates in reverse to raise the first sleeve 8 back to its initial position. At this time, the baffles 25 at the bottoms of the third sleeve 10 and the second sleeve 9 are reset under the action of the torsion springs 26 connected thereto; then, the air pumps 14 on the first sleeve 8 are turned off, and the geological samples inside the collection tank 24 of the first sleeve 8 are collected.

[0052] In this way, geological samples at different depths of shallow, medium, and deep can be collected separately through the three sleeves, and the collected geological samples do not interfere with each other, which can more comprehensively and accurately reflect the layered structure and characteristics of coal mine geology, provide detailed and reliable geological data basis for subsequent coal mine mining operations, help formulate scientific and reasonable mining plans, and improve mining efficiency.

It cannot be determined that the specific embodiments of the present invention are limited to this. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the premise of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the patent protection scope determined by the claims submitted for the present invention.
