[0053] Lifting component 2, the lifting component 2 is used to drive the insertion component 3 into the soil;

Among them, the telescopic device 201 can be a hydraulic cylinder or an electric push rod. During operation, it is interconnected with the external power supply, hydraulic source, and controller. The connecting frame 202 passes through the support frame body 101, and the support frame body 101 is used to provide restrictions for the movement of the connecting frame 202.

[0056] The clamping member 204 includes an electric push rod 2043 fixedly installed at the lower part of the lifting plate 203. The output end of the electric push rod 2043 is fixedly connected with a clamping claw 2041.

[0057] Reference Figure 7 , during the clamping operation, the electric push rod 2043 operates under the action of the external power supply and the controller, driving the clamping claw 2041 to move. By placing the clamping claws 2041 on both sides in the gap between the two blocking rings 303, the insertion cylinder 301 can be clamped. The upper blocking ring 303 can be restricted by the through hole in the middle of the lifting plate 203, thereby ensuring the stability of the insertion cylinder 301. The auxiliary rod 2042 is used to ensure the stability of the movement of the clamping claw 2041; an arc-shaped convex block can be provided at the lower part of the clamping claw 2041 for contacting the blocking ring 303 to ensure the stability of the insertion cylinder 301.

[0058] The sampling assembly 4, the sampling assembly 4 includes a sampling tube 401. The upper part of the sampling tube 401 is fixedly connected with a sampling spiral blade 402 adapted to the insertion cylinder 301. The lower end circumference of the sampling tube 401 is fixedly connected with a soil-shoveling claw 407. One soil-shoveling claw 407 is integrally fixed with the lower end of the sampling spiral blade 402. A sampling port 406 is provided at the lower part of the sampling tube 401 and at the gap between adjacent two soil-shoveling claws 407. A separation cone 7 is coaxially fixedly connected to the inner bottom wall of the sampling tube 401. A blocking arc blade 701 is fixedly connected to the conical surface of the separation cone 7. A separation neck body 8 is provided above the separation cone 7. The separation neck body 8 is located above the sampling port 406 and is fixedly connected with the sampling tube 401. A channel that gradually contracts from the upper and lower ends to the middle is provided in the separation neck body 8. A self-rotating ring 403 is fixedly connected to the outside of the soil-shoveling claw 407. A mating groove 404 is provided at the upper part of the self-rotating ring 403. A cutting knife 405 is fixedly connected to the lower circumference of the self-rotating ring 403. A dispersion cone 409 is fixedly connected to the connection part of multiple soil-shoveling claws 407. The dispersion cone 409 is coaxially arranged with the sampling tube 401. Crushing tips 408 are fixedly connected to both the upper and lower surfaces of the soil-shoveling claw 407. A leakage hole 4071 is provided at the inclined surface of the soil-shoveling claw 407;

[0059] ReferenceFigure 9 , Figure 10 , Figure 13 , Figure 17 , Figure 18 , During the sampling operation, the rotation of the sampling pipe 401 can drive the self-rotation of the sampling spiral blade 402. The sampling spiral blade 402 can push the soil from bottom to top, and can simultaneously drive the soil shovel claw 407, the rotation ring 403, and the dispersion cone 409 to rotate. The rotation ring 403 will drive the cutting knife 405 to move. The cutting knife 405 can cut soil, rocks, and weeds, facilitating the insertion of the cylinder 301 into the soil;

[0060] The soil shovel claw 407 can shovel up the clumped soil, cut the soil and coal vertically, and drive the crushing tip 408 to move. After the mixture of soil and coal passes through the leakage hole 4071, small particle substances, such as coal particles, will first fall under the action of gravity to the lower part of the soil shovel claw 407. The large pieces of soil continue to move along the soil shovel claw 407, playing a role in initially separating and screening coal particles. These particles will first be sucked into the sampling port 406 by suction; the blocking arc-shaped blade 701 will guide the movement of the particles and prevent the soil outside the blocking arc-shaped blade 701 from entering the sampling port 406, providing a movement space for the inhalation of coal particles; the crushing tip 408 can crush the clumped soil, crush the soil and coal blocks horizontally, and the dispersion cone 409 can contact the soil, playing a role in positioning and being able to disperse the soil, facilitating the soil to be pushed from bottom to top by the sampling spiral blade 402, ensuring the smooth progress of the sampling process;

[0061] When the sampling port 406 is at the depth containing coal samples, since the density of coal is usually between 1.2 and 1.6 grams per cubic centimeter, and the soil has water absorption, the density of coal will be lower than that of the deep soil, and coal particles will be lighter than the soil. At this time, the granular coal will be sucked into the separation cone 7 under negative pressure and enter the separation neck 8, and then be extracted after secondary separation by the separation neck 8. The soil or rock particles with more water content and greater density will be thrown out under the action of gravity and centrifugal force, and then fall onto the sampling spiral blade 402. Coal particles can be taken out from the deep soil faster than soil samples, and information on whether there is coal ore in the geology can be obtained faster. It is not necessary to completely take out all the deep samples to know whether there is coal in the geology, greatly increasing the efficiency of coal sampling.

[0062] A cutting tip edge 4051 is provided at the lower part of the cutting knife 405, and vertical cutting edges 4052 are symmetrically provided at the upper part of the cutting knife 405;

[0063] Reference Figure 11 , Figure 12 , The cutting tip edge 4051 is used to insert into the soil, and the vertical cutting edges 4052 are used to cut the soil.

[0064] A driving assembly 5, which is used to drive the sampling assembly 4 to rotate on its own axis and push out the soil sample;

[0065] The driving assembly 5 includes an auxiliary frame 507, a base 502, and a containing shell 501 that are fixedly installed on the lifting assembly 2. A driving motor 504 is fixedly installed on the base 502. The output end of the driving motor 504 is fixedly connected to a driving gear 505. A driven gear 506 is arranged inside the auxiliary frame 507. The driven gear 506 is fixedly installed on the sampling tube 401. A chain 508 is arranged between the driving gear 505 and the driven gear 506. A driving piece 509 is fixedly connected to the outer side of the chain 508. The driving piece 509 is adapted to the containing shell 501. A discharge shell 503 is fixedly connected to the outer side of the base 502;

[0066] Reference Figure 13 、 Figure 14 , during the driving operation, the driving motor 504 works under the action of an external power supply and a controller, drives the driving gear 505 to rotate. The driving gear 505 drives the driven gear 506 to rotate through the chain 508. The driven gear 506 drives the sampling tube 401 to rotate on its own axis, providing power for subsequent sampling actions. The moving chain 508 synchronously drives the driving piece 509 to move. The driving piece 509 can push the soil sample to the discharge shell 503 and then discharge it from the discharge shell 503.

[0067] An extraction assembly 6, which is used to extract coal particle samples;

[0068] The extraction assembly 6 includes a negative pressure base 601 that is fixedly installed on the driving assembly 5. A negative pressure device 602 is fixedly installed on the negative pressure base 601. The extraction end of the negative pressure device 602 is fixedly connected to an extraction tube 603. The extraction tube 603 is connected to the sampling tube 401 through a rotary joint 604;

[0069] Reference Figure 15 , during the extraction operation, the negative pressure device 602 works under the action of an external power supply and a controller, and extracts the particulate matter at the sampling port 406 at the lower part of the sampling tube 401 through the extraction tube 603. The particulate matter can be stone particles, coal particles, or soil particles, and then is discharged from the discharge end of the negative pressure device 602, avoiding the particulate matter from hindering the normal soil sampling movement, which is suitable for coal geological exploration sampling operations. Among them, the negative pressure device 602 can be an existing vacuum cleaner. The rotary joint 604 ensures the normal flow of gas while meeting the rotation requirement.

[0070] Working principle: The support frame 101 can be moved to the position where sampling is required through the universal wheels 103. The placement component 3 is placed in the through hole in the middle of the lifting plate 203. The electric push rod 2043 works under the action of an external power supply and a controller, driving the clamping claws 2041 to move. By using the gaps between the two clamping claws 2041 placed between the two blocking rings 303, the placement cylinder 301 can be clamped. The upper blocking ring 303 can be restricted by the through hole in the middle of the lifting plate 203, thus ensuring the stability of the placement cylinder 301;

[0071] The drive motor 504 works under the action of an external power supply and a controller, driving the driving gear 505 to rotate. The driving gear 505 drives the driven gear 506 to rotate through the chain 508. The driven gear 506 drives the sampling tube 401 to rotate, providing power for subsequent sampling actions;

[0072] At the same time, the telescopic device 201 works, driving the connecting frame 202, the lifting plate 203, and the clamping member 204 to move, thereby providing a force for the placement component 3 to insert into the soil. The lifting plate 203 can ensure the stability of the movement of the lifting plate 203 under the guidance of the support optical rod 102;

[0073] The rotation of the sampling tube 401 can drive the rotation of the sampling spiral blade 402. The sampling spiral blade 402 can push the soil from bottom to top. And it can synchronously drive the soil shoveling claw 407, the rotating ring 403, and the dispersion cone 409 to rotate. The rotating ring 403 will drive the cutting knife 405 to move. The cutting knife 405 can cut the soil, facilitating the insertion of the placement cylinder 301 into the soil. The soil shoveling claw 407 can shovel up the clumpy soil, cut the soil and coal vertically, and drive the crushing tip 408 to move. The crushing tip 408 can crush the clumpy soil, crushing the soil and coal chunks horizontally. The dispersion cone 409 can come into contact with the soil, capable of dispersing the soil, facilitating the soil to be pushed from bottom to top by the sampling spiral blade 402, ensuring the smoothness of the sampling process;

[0074] When the sampling port 406 is at the depth containing coal samples, after the mixture of broken soil and coal passes through the leakage hole 4071, small particle substances, such as coal particles, will first fall under the action of gravity to the lower part of the soil shoveling claw 407. The large chunks of soil continue to move along the soil shoveling claw 407, playing a role in initially separating and screening the coal particles. These particles will first be sucked into the sampling port 406 by suction. The blocking arc-shaped blade 701 inside will guide the movement of the particles and prevent the soil outside the blocking arc-shaped blade 701 from entering the sampling port 406, providing a movement space for the suction of the coal particles; And there are four soil shoveling claws 407. The soil shoveling claws 407 not fixed to the sampling spiral blade 402 will break and separate the massive soil, providing sufficient space and time for sucking the coal particles;

[0075] Granular coal will enter the separation neck body 8 through the separation cone 7 under the suction of negative pressure, and then be extracted after secondary separation in the separation neck body 8. Soil or rock particles with higher water content and greater density will be thrown out under the action of gravity and centrifugal force, and then be brought onto the sampling spiral blade 402 by the massive soil. Coal particles can be taken out from the deep soil faster than soil samples, and information on whether there is coal mineral in the geology can be obtained more quickly. It is not necessary to completely take out all the deep samples to know whether there is coal in the geology, which greatly improves the efficiency of coal sampling;

[0076] The cutting tip 4051 is used to insert into the soil, and the vertical cutting edge 4052 is used to cut soil, rock, and weeds, ensuring the smooth insertion of the placement cylinder 301, avoiding damage to the insertion end of the placement cylinder 301, and ensuring the smooth sampling.
