At the top of the lifting bracket 14, a first motor 15 is fixedly installed. The output end of the first motor 15 rotatably penetrates through the lifting bracket 14 and is fixedly connected to a drilling vertical rod 16 at its end. At the bottom end of the drilling vertical rod 16, a cooperating drilling bit 17 is detachably arranged. The fixing mechanism 2 includes a fixing slide plate 21 and a cross-shaped plug plate 22. An installation inner groove 18 and a cross-shaped slot 19 for cooperation are opened at the bottom end of the drilling vertical rod 16. The fixing slide plate 21 is slidably clamped in the installation inner groove 18. Symmetrically distributed V-shaped clamping plates 23 are integrally formed on the fixing slide plate 21. An installation concave hole 24 is opened on one side of the fixing slide plate 21. A fixing block 25 is fixedly installed in the installation concave hole 24. An installation rotating rod 26 is slidably inserted in the installation concave hole 24. A driving ring 27 is fixedly sleeved on the installation rotating rod 26. A driving block 28 cooperating with the fixing block 25 is integrally formed on the driving ring 27. A return torsion spring 29 is fixedly installed on one side of the driving ring 27, and the end of the return torsion spring 29 is fixedly connected to the inner wall of the installation concave hole 24. The end of the installation rotating rod 26 is fixedly connected to a fixing pull rod 210. The fixing pull rod 210 slidably penetrates through the installation inner groove 18. A fixing spring 211 is movably sleeved on the outer side of the fixing pull rod 210. The two ends of the fixing spring 211 are respectively fixedly connected to the fixing slide plate 21 and the inner wall of the installation inner groove 18. The cross-shaped plug plate 22 is fixedly installed at the top end of the drilling bit 17. An array of fixing slots 212 is opened through the cross-shaped plug plate 22. The cross-shaped plug plate 22 can be slidably inserted into the cross-shaped slot 19. The outer diameter of the cross-shaped plug plate 22 is the same as the inner diameter of the cross-shaped slot 19, thus ensuring the stable connection of the drilling bit 17. And the V-shaped clamping plates 23 can be slidably clamped in the fixing slots 212. The auxiliary mechanism 3 includes an auxiliary rotating ring 31. A fixing inner groove 213 and a fixing concave hole 214 for cooperation are opened on the fixing pull rod 210. The auxiliary rotating ring 31 is slidably clamped in the fixing inner groove 213.

[0030] By adopting the above technical solution, during use, the mounting bracket 11 is fixed, and then the cylinder body 12 and the first motor 15 are started. At this time, the cylinder body 12 will drive the cylinder slider 13 to gradually move downward, thereby driving the lifting bracket 14 to gradually move downward, and further driving the drilling vertical rod 16 and the drilling bit 17 to gradually move downward. At the same time, the first motor 15 will drive the drilling vertical rod 16 to rotate, thereby driving the drilling bit 17 to rotate, and further enabling drilling of the sampling site. And during subsequent use, when the drilling bit 17 needs to be replaced, the user needs to simultaneously press against the two fixed pull rods 210 and hold the two auxiliary handwheels 34 to move in opposite directions, thereby driving the two auxiliary pull rods 32 and the auxiliary rotating ring 31 to move in opposite directions and compress the auxiliary spring 33. Then, the two auxiliary handwheels 34 are synchronously rotated, thereby driving the fixed pull rod 210 to rotate, and further driving the mounting rod 26 and the driving ring 27 to rotate, and further driving the driving block 28 to rotate and twist the reset torsion spring 29. When the driving block 28 rotates 180 degrees, the rotation of the auxiliary handwheel 34 is stopped. At this time, the driving block 28 will correspond to the corresponding fixed block 25. Then, the pressure on the fixed pull rod 210 is removed and the two auxiliary handwheels 34 are pulled again to move in opposite directions, thereby driving the two fixed sliding plates 21 to move in opposite directions, and further driving the corresponding V-shaped clamping plate 23 to move and gradually separate from the corresponding fixed slot 212. When the distance between the two fixed sliding plates 21 reaches the maximum, the V-shaped clamping plate 23 is completely separated from the corresponding fixed slot 212. After that, the used drilling bit 17 is removed, and the cross-shaped insertion plate 22 at the top of another new drilling bit 17 is inserted into the cross-shaped slot 19. Then, the above steps are reversed to reset the V-shaped clamping plate 23, etc.

A connecting jack 410 is opened through the upper end of the L-shaped sealing plate 43, and the end of the output end of the first multi-stage electric push rod 41 is fixedly inserted into the connecting jack 410. The arrangement of the connecting jack 410 provides guarantee for the stable connection between the first multi-stage electric push rod 41 and the L-shaped sealing plate 43.

[0032] By adopting the above technical solution, during use, when drilling to an appropriate depth, the four first multi-stage electric push rods 41 are sequentially activated, so as to be able to drive the corresponding four L-shaped sealing plates 43 to move upward in sequence. And when the L-shaped sealing plate 43 moves to the upper end of the corresponding sampling slot 44, the corresponding first multi-stage electric push rod 41 is paused and the corresponding electric telescopic rod 45 is activated, so as to be able to drive the corresponding arc-shaped sealing plate 46 to move away from the sampling slot 44, and then the corresponding sample can be introduced from the corresponding sampling slot 44 into the corresponding sampling vertical pipe 42. During this period, the corresponding sample will push the corresponding lifting piston 47 upward, so as to be able to squeeze the corresponding sampling spring 48 and discharge the air in the corresponding sampling vertical pipe 42 through the corresponding air guide horizontal pipe 49. And when an appropriate amount of sample is taken in the corresponding sampling vertical pipe 42, the corresponding arc-shaped sealing plate 46 and the L-shaped sealing plate 43 can be reset. In addition, when the sampling operation is completed, the four L-shaped sealing plates 43 need to be moved upward to the highest position in sequence. Subsequently, the four T-shaped limit rings 54 need to be held and rotated in sequence. And when the corresponding limit convex block 53 moves from the horizontal part of the corresponding L-shaped limit groove 55 to the vertical part, the rotation of the T-shaped limit ring 54 is stopped and it is pushed upward, so as to be able to squeeze the corresponding limit spring 56 and separate the T-shaped limit ring 54 from the corresponding limit concave hole 411. Then the sampled sampling vertical pipe 42 is taken out and another unused sampling vertical pipe 42 is inserted and fixed.

[0034] By adopting the above technical solution, during use, when the arc-shaped plugging plate 46 and the L-shaped plugging plate 43 are reset after the sampling operation, the second multi-stage electric push rod 64 needs to be started, so as to be able to drive the lifting support plate 617 to move downward, and further be able to drive the driving gear 619 and the arrow toggle 620 to move. Further, according to the position of the corresponding sampling vertical pipe 42, the driving gear 619 can be fully engaged with the first gear 67, the second gear 610, the third gear 613, or the fourth gear 616 respectively. At this time, the arrow toggle 620 will contact and push the corresponding first rack 623, second rack 624, third rack 625, or fourth rack 626 to move, so as to be able to drive the corresponding sliding sleeve block 621 to move and compress the corresponding return spring 622, and further be able to separate the first rack 623, second rack 624, third rack 625, or fourth rack 626 from the corresponding first gear 67, second gear 610, third gear 613, or fourth gear 616 respectively. After that, the second motor 618 will drive the driving gear 619 to rotate, so as to be able to drive the first gear 67, the second gear 610, the third gear 613, or the fourth gear 616 to rotate, and further be able to drive the first plugging plate 63 through the driven rotating rod 66, drive the second plugging plate 69 through the first rotating pipe 68, drive the third plugging plate 612 through the second rotating pipe 611, or drive the fourth plugging plate 615 through the third rotating pipe 614 to rotate, and further be able to remove the plugging of the corresponding three blowing-off conduits 62 corresponding to the sampling vertical pipe 42. At this time, the pressurized air will be led out from the corresponding three blowing-off conduits 62 and clean the bottom end of the corresponding connecting through groove 111, so as to ensure the normal plugging of the corresponding connecting through groove 111 again after sampling.

[0035] Working principle: When in use, fix the mounting bracket 11, and then start the cylinder body 12 and the first motor 15. At this time, the cylinder body 12 will drive the cylinder slider 13 to move downward step by step, so as to drive the lifting bracket 14 to move downward step by step, and further drive the drilling vertical rod 16 and the drilling bit 17 to move downward step by step. At the same time, the first motor 15 will drive the drilling vertical rod 16 to rotate, so as to drive the drilling bit 17 to rotate, and then be able to drill the sampling site. And during subsequent use, when the drilling bit 17 needs to be replaced, the user needs to simultaneously resist the two fixed pull rods 210 and hold the two auxiliary handwheels 34 to move in the opposite direction, so as to drive the two auxiliary pull rods 32 and the auxiliary rotating ring 31 to move in the opposite direction and compress the auxiliary spring 33. Then synchronously rotate the two auxiliary handwheels 34, so as to drive the fixed pull rod 210 to rotate, and further drive the mounting rotating rod 26 and the driving dial ring 27 to rotate, and further drive the driving block 28 to rotate and twist the reset torsion spring 29. When the driving block 28 rotates 180 degrees, stop rotating the auxiliary handwheel 34. At this time, the driving block 28 will correspond to the corresponding fixed block 25. Then remove the resistance to the fixed pull rod 210 and pull the two auxiliary handwheels 34 to move in the opposite direction again, so as to drive the two fixed sliding plates 21 to move in the opposite direction, and further drive the corresponding V-shaped clamping plate 23 to move and gradually separate it from the corresponding fixed slot 212. When the distance between the two fixed sliding plates 21 reaches the maximum, the V-shaped clamping plate 23 is completely separated from the corresponding fixed slot 212. After that, remove the used drilling bit 17 and insert the cross-shaped insertion plate 22 at the top of another new drilling bit 17 into the cross-shaped slot 19. Then reverse the operation according to the above steps to reset the V-shaped clamping plate 23, etc.;

[0036] When drilling to an appropriate depth, the four first multi-stage electric push rods 41 are sequentially activated, so as to drive the corresponding four L-shaped sealing plates 43 to move upward in sequence. When the L-shaped sealing plate 43 moves to the upper end of the corresponding sampling slot 44, the corresponding first multi-stage electric push rod 41 is paused and the corresponding electric telescopic rod 45 is activated, so as to drive the corresponding arc-shaped sealing plate 46 to move to the side away from the sampling slot 44, and then the corresponding sample can be introduced from the corresponding sampling slot 44 into the corresponding sampling vertical pipe 42. During this period, the corresponding sample will push the corresponding lifting piston 47 upward, so as to compress the corresponding sampling spring 48 and introduce the air in the corresponding sampling vertical pipe 42 into the air collection inner groove 113 through the corresponding air guide cross pipe 49 and the one-way valve body 61 for pressurization. When an appropriate amount of sample is taken in the corresponding sampling vertical pipe 42, the corresponding arc-shaped sealing plate 46 and the L-shaped sealing plate 43 can be reset. In addition, when the sampling operation is completed, the four L-shaped sealing plates 43 need to be moved upward to the highest position in sequence. Then, the four T-shaped limit rings 54 need to be held and rotated in sequence. When the corresponding limit convex block 53 moves from the horizontal part of the corresponding L-shaped limit slot 55 to the vertical part, the rotation of the T-shaped limit ring 54 is stopped and it is pushed upward, so as to compress the corresponding limit spring 56 and separate the T-shaped limit ring 54 from the corresponding limit concave hole 411. Then, the sampled sampling vertical pipe 42 is taken out and another unused sampling vertical pipe 42 is inserted and fixed;

[0037] During this period, when the arc-shaped plugging plate 46 and the L-shaped plugging plate 43 are reset after the sampling operation, the second multi-stage electric push rod 64 needs to be started, so as to drive the lifting support plate 617 to move downward, and then drive the driving gear 619 and the arrow dial rod 620 to move. Further, according to the position of the corresponding sampling vertical pipe 42, the driving gear 619 can be respectively fully engaged with the first gear 67, the second gear 610, the third gear 613 or the fourth gear 616. At this time, the arrow dial rod 620 will contact and push the corresponding first rack 623, second rack 624, third rack 625 or fourth rack 626 to move, so as to drive the corresponding sliding sleeve block 621 to move and compress the corresponding return spring 622. Further, the first rack 623, second rack 624, third rack 625 or fourth rack 626 can be separated from the corresponding first gear 67, second gear 610, third gear 613 or fourth gear 616 respectively. Then, the second motor 618 will drive the driving gear 619 to rotate, so as to drive the first gear 67, second gear 610, third gear 613 or fourth gear 616 to rotate. Further, the first plugging plate 63 can be driven to rotate through the driven rotating rod 66, the second plugging plate 69 can be driven to rotate by the first rotating pipe 68, the third plugging plate 612 can be driven to rotate by the second rotating pipe 611 or the fourth plugging plate 615 can be driven to rotate by the third rotating pipe 614. Further, the plugging of the corresponding three blowing ducts 62 corresponding to the sampling vertical pipe 42 can be removed. At this time, the pressurized air will be led out from the corresponding three blowing ducts 62 and clean the bottom end of the corresponding connection through groove 111, so as to ensure the normal plugging of the corresponding connection through groove 111 again after sampling.
