Description

Technical Field

[0001] This invention relates to the field of geological exploration and sampling technology, specifically to a geological exploration sampler and method. Background Technology

[0002] Geological exploration is an activity widely used in earth science research and resource development. Its main purpose is to conduct detailed investigations and analyses of the geological conditions below the earth's surface using various technical means.

[0003] CN213688965U discloses a sampler for geological exploration, comprising a motor, a connecting block fixedly connected to one end of the motor's output shaft, and a drill rod fixedly connected to the bottom of the connecting block. An installation block is fixedly connected to one side of the drill rod, and a lead screw is movably connected to one side of the installation block. A sealing plug is fixedly connected to one end of the lead screw. A sealing groove is formed at one end of the drill rod, and the sealing groove and the sealing plug are movably connected. A vent is provided on one side of the drill rod. A knob is fixedly connected to one end of the lead screw, passing through one side of the installation block. A housing is fixedly connected to the outside of the motor, and connecting rods are fixedly connected to both outer walls of the housing, with handles fixedly connected to one end of each connecting rod. This application allows the sample to automatically slide into a sampling container after drilling soil or rock material, facilitating subsequent exploration and testing by exploration personnel. It also prevents sample adhesion to the inner wall of the drill rod, avoiding blockage and ensuring secondary use.

[0004] In existing technologies, when using the aforementioned devices, it is necessary to manually hold the handle before starting the drilling tool to drill into the ground. However, during the drilling process, it was found that drilling requires a vertical downward motion, and manually controlling the descent of the drilling equipment inevitably leads to angular deviations. These deviations increase the drilling area, causing damage to surrounding vegetation. Furthermore, the aforementioned equipment uses manual sampling, which is insufficient to meet the required force and cannot effectively sample deep geological layers. This not only makes sampling inconvenient but also time-consuming and labor-intensive. Moreover, after most of the drilling work is completed, the collection pipe needs to be manually disassembled from the drilling pipe to facilitate soil extraction. However, entering the pipe with one's hands increases the risk of cuts and provides no safety guarantee. Summary of the Invention

[0014] A sampling method for geological exploration includes the following steps: S1. First, place the sampling tube into the drill pipe, use the limiting rod and the slot to fix the sampling tube in the drill pipe, and then start the drilling operation. S2, the soil generated during drilling will enter the sampling tube from the drill pipe. After the sampling work is completed, the drilling work will be stopped.

[0015] The beneficial effects of this invention are: This invention utilizes a sampling tube to collect soil. The internal clamping plates secure the soil as the sampling tube rises, preventing it from falling. A limiting rod and groove further stabilize the tube, preventing it from wobbling during rotation.

[0016] This invention, through the setting of the connecting block, can contact the snap-fit ​​cap on the sampling tube, and use the snap-fit ​​cap to drive the triangular block to rise, thereby causing the top block to lose contact with the limit rod, thus canceling the connection between the sampling tube and the drill pipe, facilitating the disassembly of the sampling tube. Furthermore, through the setting of the snap-fit ​​cap and the sliding buckle, the snap-fit ​​block can be used to automatically cancel the lock without manual cancellation, improving practicality and disassembly efficiency. In addition, there is a sliding column on the side wall of the snap-fit ​​block, which can be manually pulled to perform maintenance when the snap-fit ​​block is stuck, providing subsequent protection.

[0017] The present invention, through the setting of a collection plate in the collection mechanism, can drive the collection plate to the bottom of the sampling tube during the upward process of the sampling tube. After passing through the setting of the baffle, the soil in the sampling tube can be squeezed onto the collection plate for collection. Then the soil on the collection plate is stored. Then the sampling tube is placed in the borehole for deep sampling, and the sampling is collected again. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-14 As shown, this application provides a sampler for geological exploration, including a working base plate 1, a working middle plate 12, and a working top plate 14, and further comprising: Drilling mechanism 2 is mounted on working base plate 1; Collection mechanism 3 is installed on the working plate 12; The lifting mechanism 4 is installed on the working top plate 14; Sampling mechanism 5 is located inside drilling mechanism 2; Toolbox 6 is set on the working base plate 1; During operation, the sampling mechanism 5 is placed inside the drilling mechanism 2, and then the drilling mechanism 2 is driven to perform drilling and sampling. The sampled soil will enter the sampling mechanism 5. Then, the lifting mechanism 4 is used to pull the sampling mechanism 5 out of the drilling mechanism 2. At the same time, the collecting mechanism 3 is used to collect the soil in the sampling mechanism 5. After the collection is completed, the sampling mechanism 5 is put back into the drilling mechanism 2 for deep sampling.

[0023] like Figure 2 and Figure 9 As shown, the drilling mechanism 2 includes a drill pipe 24; a limiting groove 243 and a lifting groove 244 are formed inside the drill pipe 24; an upper tooth 242 and a lower tooth 245 are fixedly connected to the side wall of the lifting groove 244; the upper tooth 242 and the lower tooth 245 are arranged opposite to each other; the sampling mechanism 5 includes a sampling tube 51; the sampling tube 51 is slidably disposed inside the drill pipe 24; a vertical plate 52 is fixedly connected to the top of the sampling tube 51; a column 521 is fixedly connected to the middle of the vertical plate 52; springs 1 522 are fixedly connected to both sides of the column 521; a limiting rod 523 is fixedly connected to the end of spring 1 522 away from the column 521; the limiting rod 523 movably abuts against the limiting groove 243; the bottom of the limiting rod 523 is hinged to the vertical plate 52; a second spring 524 is fixedly connected to the top of the column 521; a triangular block 525 is fixedly connected to the end of spring 2 524 away from the column 521; telescopic grooves 526 are formed on both sides of the triangular block 525; A top post 527 and a spring 528 are fixedly connected inside the expansion groove 526; a top block 529 is fixedly connected to the end of the spring 528 away from the expansion groove 526; the top block 529 is slidably disposed inside the expansion groove 526; the top block 529 is in movable contact with the limiting rod 523; a slot 513 is opened on the side wall of the sampling tube 51; an expansion tube 511 is fixedly connected to the inner wall of the sampling tube 51; a pressure plate 512 is fixedly connected to the end of the expansion tube 511 away from the sampling tube 51; both ends of the pressure plate 512 are slidably disposed inside the slot 513; a fixed tube 55 is fixedly connected to the bottom of the sampling tube 51; a threaded post 54 is rotatably connected to the side wall of the fixed tube 55; a driven gear 541 is fixedly connected to the side wall of the threaded post 54; the driven gear 541 is movably meshed with the upper tooth 242 and the lower tooth 245; a clamping plate 542 is rotatably connected to the end of the threaded post 54 away from the driven gear 541; the clamping plate 542 is located inside the fixed tube 55. During operation, when drilling is required, the sampling tube 51 is placed into the drill pipe 24. During placement, the driven gear 541 on the side wall of the sampling tube 51 is aligned with the lifting groove 244 on the drill pipe 24. Upon placement, the driven gear 541 engages with the upper teeth 242 on the lifting groove 244, and the upper teeth 242 drive the threaded post 54 on the sampling tube 51 to rotate. This rotation moves the internal clamping plate 542 towards the center of the fixed pipe 55, reducing the distance between the two sets of clamping plates 542. The sampling tube 51 is then continued to be placed into the drill pipe 24. During this continuous placement, the limiting rod 523 on the sampling tube 51 abuts against the inner wall of the drill pipe 24. After the sampling tube 51 is placed in the designated position, the limiting rod 523 reaches the limit of the drill pipe 24. At the location groove 243, since the limiting groove 243 is concave, the limiting rod 523 will lose contact with the inner wall of the borehole when it reaches the groove, thus springing into the limiting groove 243, thereby fixing the sampling tube 51 inside the drill pipe 24. At the same time, when the sampling tube 51 reaches the designated position, the driven gear 541 will mesh with the lower tooth 245 on the opposite side again, and will be driven to rotate again by the lower tooth 245. This rotation will drive the driven gear 541 to reverse, thereby increasing the distance between the two sets of clamping plates 542, facilitating the entry of soil. Then the drilling work will begin. When the soil in the sampling tube 51 needs to be removed after drilling is completed, the lifting mechanism 4 will drive the triangular block 525 to rise. When the triangular block 525 rises, the top blocks 529 on both sides of the triangular block 525 will lose contact with the limiting rod. After the limiting rod 523 loses contact with the triangular block 525, it will be pulled back by the springs 522 on both sides of the central column, thus losing its engagement with the limiting groove 243. After losing the engagement, the sampling tube 51 can be taken out. After the soil in the sampling tube 51 is removed, the sampling tube 51 is put into the drill pipe 24. After insertion, the lifting mechanism 4 is disconnected from the triangular block 525. After the triangular block 525 loses its connection, it will be pulled back by the spring 524. When pulled back, the top blocks 529 on both sides of the triangular block 525 will contact the limiting rod 523 again and push the limiting rod 523 into the limiting grooves 243 on both sides. At the same time, the top columns 527 in the telescopic grooves 526 on both sides of the triangular block 525 will limit the top blocks 529. When the limiting rod 523 is abutted by the top blocks 529, the two sets of springs Spring 522 continues to apply tension to the limiting rod 523, preventing the applied tension from squeezing the top block 529 into the telescopic groove 526. This allows the top column 527 to block the top block 529. When spring 522 applies tension, the top column 527 can abut against the top block 529 and the limiting rod 523, thus preventing the limiting rod 523 from falling out of the limiting groove 243. The sampling tube 51 allows for soil collection, and the clamping plates 542 inside the fixing tube 55 clamp the soil tightly as the sampling tube 51 rises, preventing soil from falling during ascent. Simultaneously, the limiting rod 523 and the limiting groove 243 fix the sampling tube 51, preventing it from swaying inside the drill tube 24 during rotation.Meanwhile, the triangular block 525 facilitates the disassembly of the sampling tube 51, avoiding manual entry into the drill pipe 24 for disassembly. The working base plate 1 stabilizes the drill pipe 24 during drilling, preventing displacement. Furthermore, the triangular block 525 and the limiting rod 523 facilitate the removal of the sampling tube 51 from the drill pipe 24 without manual disassembly.

[0024] like Figures 3-5 As shown, a threaded pipe 241 is fixedly connected to the top of the drill pipe 24; a cylinder 21 is fixedly connected to the working base plate 1; a drive plate 211 is fixedly connected to the end of the cylinder 21 away from the working base plate 1; a connecting bolt 23 is fixedly connected to the bottom of the drive plate 211; the connecting bolt 23 is threadedly connected to the threaded pipe 241; and a drilling tooth 246 is fixedly connected to the bottom of the drill pipe 24. During operation, the threaded tube 241 is connected to the connecting bolt 23 by thread. Then, the connecting bolt 23 is driven to rotate, which in turn drives the threaded tube 241 to rotate, and then drives the drill pipe 24 to rotate. The drilling teeth 246 are used to carry out drilling and sampling work. The drilled soil will enter the sampling tube 51 to realize the soil collection work.

[0025] like Figures 6-9 As shown, the lifting mechanism 4 includes a second cylinder 41; the second cylinder 41 is fixedly connected to the working top plate 14; a connecting column 42 is fixedly connected to the end of the second cylinder 41 away from the working top plate 14; a connecting block 43 is fixedly connected to the end of the connecting column 42 away from the second cylinder 41; a slot 431 is provided in the middle of the connecting block 43; a sliding groove 44 is provided on the side wall of the connecting block 43; a fixing plate 441 is fixedly connected in the sliding groove 44; a telescopic spring 442 is fixedly connected to the side wall of the fixing plate 441; a locking block 44 is fixedly connected to the end of the telescopic spring 442 away from the fixing plate 441. 3; A sliding column 444 is fixedly connected to the side wall of the snap-fit ​​block 443; the sliding column 444 is set through the sliding groove 44; a connecting arm 53 is fixedly connected to the side wall of the triangular block 525; the connecting arm 53 is set through the vertical plate 52; a connecting plate 531 is fixedly connected to the end of the connecting arm 53 away from the triangular block 525; the connecting plate 531 is located above the triangular block 525; a snap-fit ​​cap 532 is fixedly connected to the connecting plate 531; a sliding buckle 533 is slidably connected to the snap-fit ​​cap 532; the sliding buckle 533 is located below the snap-fit ​​cap 532; the snap-fit ​​block 443 and the snap-fit ​​cap 532 are movably snap-fitted together; During operation, after drilling and extraction are completed, when the sampling tube 51 needs to be removed from the drill pipe 24, the second drive cylinder 41 descends. During descent, it pulls the connecting block 43 into the drill pipe 24, aligning it with the lower locking cap 532 and continuing to descend until the locking cap 532 is positioned in the locking groove 431 in the middle of the connecting block 43. After the locking cap 532 reaches the locking groove 431, the locking block 443 in the locking groove 431 will contact the locking cap 532 during the descent of the connecting block 43 and be pressed into the sliding groove 44 by the locking cap 532 during the continuous descent. After the top of the locking cap 532 abuts against the top of the locking groove 431, the locking cap 532 is higher than the locking block 443. At this point, the locking block 443 springs back into the locking groove 431, and then the second drive cylinder 41 drives the connecting block 443 to descend. As block 43 rises, the locking cap 532, engaged by locking block 443, causes the connecting plate 531 below to rise. This, in turn, uses connecting arm 53 to pull triangular block 525 upwards. As triangular block 525 rises, top block 529 loses contact with limit rod 523, and sampling tube 51 loses its fixation by limit rod 523, causing sampling tube 51 to rise and remove the internal soil. After the soil is removed, sampling tube 51 is placed into drill pipe 24 again, using connecting block 43 to insert it. Once sampling tube 51 is in the designated position, connecting block 43 continues to descend. During descent, triangular block 525 is pulled by spring 524, and locking cap 532 also loses contact with locking block 443, causing triangular block 525 to be pulled by the spring. As block 524 is pulled downwards, top block 529 gradually contacts limit rod 523. During descent, the internal locking block 443 of connecting block 43 contacts the sliding buckle 533 below locking cap 532 and is pressed back into slide groove 44 by the sliding buckle 533. Connecting block 43 continues to descend, reaching below sliding buckle 533. Since sliding buckle 533 has a double-sloped design, after descending to the bottom, it drives connecting block 43 to rise. During this rise, locking block 43 drives sliding buckle 533 to rise simultaneously via locking block 443. After sliding buckle 533 contacts locking cap 532, it is blocked. At this point, locking block 443 is pressed back into slide groove 44 by the sloping sliding buckle 533. Then, after continuous rise via sliding buckle 533 and locking cap 532, it finally contacts locking cap 523. Separating 532 cancels the connection between connecting block 43 and snap-fit ​​cap 532, then triangular block 525 returns to its original position. Top block 529 pushes limiting rod 523 into limiting groove 243. Connecting block 43 can contact snap-fit ​​cap 532 on sampling tube 51, and snap-fit ​​cap 532 drives triangular block 525 upward, causing top block 529 to lose contact with limiting rod 523, thus canceling the connection between sampling tube 51 and drill pipe 24, facilitating disassembly of sampling tube 51. Furthermore, the snap-fit ​​cap 532 and sliding buckle 533, in conjunction with snap-fit ​​block 443, automatically release the lock without manual release, improving practicality and disassembly efficiency. A sliding post 444 is provided on the side wall of snap-fit ​​block 443.If the locking block 443 is stuck, maintenance can be performed by manually pulling the sliding pin 444, providing subsequent protection.

[0026] like Figures 10-12 As shown, the collection mechanism 3 includes a movable box 31; two sets of movable boxes 31 are provided; the movable box 31 is fixedly connected to the working plate 12; a movable screw 33 is rotatably connected to the side wall of the movable box 31; a drive gear 35 is fixedly connected to the movable screw 33; an external tooth 514 is fixedly connected to the side wall of the sampling tube 51; the external tooth 514 is movably meshed with the drive gear 35; a movable block 341 is threadedly connected to the movable screw 33; a collection plate 34 is fixedly connected to the side wall of the movable block 341; a baffle 32 is fixedly connected to the side wall of the movable box 31; two sets of baffles 32 are provided; a pressure plate 512 movably abuts against the baffle 32. During operation, when the sampling tube 51 is raised to the working plate 12 via the connecting block 43, the external teeth 514 on the sampling tube 51 first mesh with the drive gear 35 on the moving screw 33, and drive the drive gear 35 to rotate as it rises. During rotation, the bidirectional screw drives the moving block 341 and the collection plate 34 to move towards the sampling tube 51. As the sampling tube 51 rises, the collection plate 34 moves below the sampling tube 51. Simultaneously, after the external teeth 514 contact the drive gear 35, the pressure plate 512 on the sampling tube 51 contacts the baffle 32 and is blocked by the baffle 32. As the sampling tube 51 continues to rise, the pressure plate 512, blocked by the baffle 32, pushes the soil inside the sampling tube 51 out, causing it to fall onto the collection plate 34 for collection. During descent, the external teeth... 514 drives the drive gear 35 to reverse, thereby retracting the collection plate 34. The pressure plate 512 is circular, with its two protruding parts sliding in the slot 513. When the sampling tube 51 reaches the drill pipe 24, the pressure plate 512 is still below the sampling tube 51. When the drill pipe 24 drills downward, the soil comes into contact with the pressure plate 512. As the drill pipe 24 continues to descend, the pressure plate 512 is also lifted by the soil. Through the setting of the collection plate 34 in the collection mechanism 3, the collection plate 34 can be driven to reach below the sampling tube 51 during the upward process of the sampling tube 51. After the setting of the baffle 32, the soil in the sampling tube 51 can be squeezed onto the collection plate 34 for collection. Then the soil on the collection plate 34 is stored. Then the sampling tube 51 is placed back into the drill hole for deep sampling. After sampling, it is collected again.

[0027] like Figure 2 As shown, a support column 11 is fixedly connected to the working base plate 1; multiple sets of support columns 11 are provided; the end of the support column 11 away from the working base plate 1 is fixedly connected to the working plate 12; a support column 23 is fixedly connected to the working plate 12; multiple sets of support columns 23 are provided; the end of the support column 23 away from the working plate 12 is fixedly connected to the working top plate 14. During operation, multiple sets of support columns support the working base plate 1, the working middle plate 12, and the working top plate 14 before drilling and mining operations can proceed.

[0028] like Figure 2 As shown, a drilling motor 22 is fixedly connected to the top of the drive board 211; the drill pipe 24 is driven by the drilling motor 22. During operation, drilling and extraction are carried out by drilling motor 22, eliminating the need for manual drilling and extraction.

[0029] like Figure 6 As shown, the drill pipe 24 is installed through the working base plate 1; During operation, the drill pipe 24 descends continuously through the working base plate 1 to achieve drilling and extraction.

[0030] Please see Figures 1-14 As shown, this application provides a sampling method for geological exploration, including the following steps: S1. First, place the sampling tube 51 into the drill pipe 24. Use the limiting rod 523 and the slot 513 to fix the sampling tube 51 into the drill pipe 24. Then start the drilling operation. S2, the soil generated during drilling will enter the sampling tube 51 from the drill pipe 24. After the sampling work is completed, the drilling work will be stopped. Then, the connecting block 43 will be driven down by the cylinder 2 41. The connecting block 43 will be connected to the snap-fit ​​cap 532 on the sampling tube 51, and the sampling tube 51 will be driven up to the top of the working plate 12. S3, after rising above the working plate 12, the soil in the sampling tube 51 is collected by the collection plate 34, and then the sampling tube 51 is placed into the drill pipe 24 and continuously descended to collect the soil until the sampling work is completed. During operation, the sampling tube 51 is first placed into the drill pipe 24. The limiting rod 523 and the slot 513 are used to fix the sampling tube 51 into the drill pipe 24. Then, the drilling operation is started. The soil generated during drilling will enter the sampling tube 51 from the drill pipe 24. After the sampling is completed, the drilling operation is stopped. Then, the connecting block 43 is driven down by the cylinder 41. The connecting block 43 is connected to the snap cap 532 on the sampling tube 51 and drives the sampling tube 51 to rise above the working plate 12. After rising above the working plate 12, the soil in the sampling tube 51 is collected by the collecting plate 34. Then, the sampling tube 51 is put back into the drill pipe 24 and continues to descend for sampling until the sampling is completed.

[0031] The working principle of this invention is as follows: When drilling is required, the sampling tube 51 is placed into the drill pipe 24. During placement, the driven gear 541 on the side wall of the sampling tube 51 is aligned with the lifting groove 244 on the drill pipe 24. During placement, the driven gear 541 engages with the upper teeth 242 on the lifting groove 244, and the upper teeth 242 drive the threaded post 54 on the sampling tube 51 to rotate. During rotation, the internal clamping plate 542 moves towards the middle of the fixed tube 55, thereby reducing the distance between the two sets of clamping plates 542. Then, the sampling tube 51 is continued to be placed into the drill pipe 24. During continuous placement, the limiting rod 523 on the sampling tube 51 abuts against the inner wall of the drill pipe 24. After the sampling tube 51 is placed in the designated position, the limiting rod 523 will reach the drill pipe 24. At the limiting groove 243 of the 4, since the limiting groove 243 is concave, the limiting rod 523 will lose contact with the inner wall of the borehole when it reaches the groove, thus springing into the limiting groove 243, thereby fixing the sampling tube 51 inside the drill pipe 24. At the same time, when the sampling tube 51 reaches the designated position, the driven gear 541 will mesh with the lower tooth 245 on the opposite side again, and will be driven to rotate again by the lower tooth 245. This rotation will drive the driven gear 541 to reverse, thereby increasing the distance between the two sets of clamping plates 542, facilitating the entry of soil. Then the drilling work begins. When the soil in the sampling tube 51 needs to be removed after drilling, the lifting mechanism 4 will drive the triangular block 525 to rise. When the triangular block 525 rises, the top blocks 529 on both sides of the triangular block 525 will lose contact with the limiting groove 24. When the positioning rod 523 is engaged, after the limiting rod 523 loses engagement with the triangular block 525, it will be pulled back by the springs 522 on both sides of the central column, thus losing its engagement with the limiting groove 243. After losing engagement, the sampling tube 51 can be taken out. After the soil in the sampling tube 51 is removed, the sampling tube 51 is put into the drill pipe 24. After insertion, the lifting mechanism 4 is disconnected from the triangular block 525. After the triangular block 525 loses its connection, it will be pulled back by the spring 524. When pulled back, the top blocks 529 on both sides of the triangular block 525 will contact the limiting rod 523 again, and push the limiting rod 523 into the limiting grooves 243 on both sides. At the same time, the top columns 527 in the telescopic grooves 526 on both sides of the triangular block 525 will limit the top blocks 529. When the limiting rod 523 is engaged by the top blocks 529, the two sets of Spring 522 continues to apply tension to the limiting rod 523, preventing the applied tension from squeezing the top block 529 into the telescopic groove 526. This allows the top column 527 to block the top block 529. When spring 522 applies tension, the top column 527 can abut against the top block 529 and the limiting rod 523, thus preventing the limiting rod 523 from falling out of the limiting groove 243. The sampling tube 51 allows for soil collection, and the clamping plates 542 inside the fixing tube 55 clamp the soil tightly as the sampling tube 51 rises, preventing soil from falling during ascent. Simultaneously, the limiting rod 523 and the limiting groove 243 fix the sampling tube 51, preventing it from swaying inside the drill tube 24 during rotation.Meanwhile, the triangular block 525 facilitates the disassembly of the sampling tube 51, avoiding manual entry into the drill pipe 24 for disassembly. The working base plate 1 stabilizes the drill pipe 24 during drilling, preventing displacement. Furthermore, the triangular block 525 and the limiting rod 523 facilitate the removal of the sampling tube 51 from the drill pipe 24 without manual disassembly.

[0032] When the drilling operation is completed and the sampling tube 51 needs to be removed from the drill pipe 24, the second cylinder 41 descends. During descent, it pulls the connecting block 43 into the drill pipe 24, aligning it with the lower locking cap 532 and continuing to descend until the locking cap 532 is positioned in the locking groove 431 in the middle of the connecting block 43. After the locking cap 532 reaches the locking groove 431, the locking block 443 in the groove 431 will contact the locking cap 532 during the descent of the connecting block 43 and be pressed into the sliding groove 44 by the locking cap 532 during the continuous descent. After the top of the locking cap 532 abuts against the top of the locking groove 431, the locking cap 532 is higher than the locking block 443. At this point, the locking block 443 springs back into the locking groove 431, and the second cylinder 41 then drives the connecting block... As the drill pipe rises, the locking cap 532 is engaged by the locking block 443, causing the connecting plate 531 below to rise. This, in turn, uses the connecting arm 53 to pull the triangular block 525 upwards. As the triangular block 525 rises, the top block 529 loses contact with the limiting rod 523, and the sampling tube 51 loses its fixation by the limiting rod 523, thus causing the sampling tube 51 to rise and remove the internal soil. After the soil is removed, the sampling tube 51 is placed back into the drill pipe 24, and the connecting block 43 is used to insert it. Once the sampling tube 51 is in the designated position, the connecting block 43 continues to descend. During this descent, the triangular block 525 is pulled by the second spring 524, and the locking cap 532 also loses contact with the locking block 443. The triangular block 525 is then pulled by the second spring 524. 524 is pulled downwards, causing the top block 529 to gradually contact the limit rod 523. As the connecting block 43 descends, the internal locking block 443 contacts the sliding buckle 533 below the locking cap 532 and is pressed back into the slide groove 44 by the sliding buckle 533. The connecting block 43 continues to descend, reaching below the sliding buckle 533. Since the sliding buckle 533 has a double-sloped design, after descending to the bottom, it drives the connecting block 43 to rise. During this rise, the locking block 443 drives the sliding buckle 533 to rise simultaneously. When the sliding buckle 533 contacts the locking cap 532, it is blocked. At this point, the locking block 443 is pressed back into the slide groove 44 by the sloping sliding buckle 533. Then, after the sliding buckle 533 and locking cap 532 continue to rise, the connecting block 43 finally contacts the locking cap 532. Separating 532 cancels the connection between connecting block 43 and snap-fit ​​cap 532, then triangular block 525 returns to its original position. Top block 529 pushes limiting rod 523 into limiting groove 243. Connecting block 43 can contact snap-fit ​​cap 532 on sampling tube 51, and snap-fit ​​cap 532 drives triangular block 525 upward, causing top block 529 to lose contact with limiting rod 523, thus canceling the connection between sampling tube 51 and drill pipe 24, facilitating disassembly of sampling tube 51. Furthermore, the snap-fit ​​cap 532 and sliding buckle 533, in conjunction with snap-fit ​​block 443, automatically release the lock without manual release, improving practicality and disassembly efficiency. A sliding post 444 is provided on the side wall of snap-fit ​​block 443.If the locking block 443 is stuck, maintenance can be performed by manually pulling the sliding pin 444, providing subsequent protection.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
