Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and particularly to a geological soil sampling device for ecological restoration. Background Art

[0002] A sampling drill is a device that drills into soil and rock through a rotatable sampling cylinder. When conducting ecological restoration on soil and rock, in order to understand the pollution situation and degree of the soil and rock, it is necessary to take samples of the soil and rock for testing. At this time, a sampling drill is used to take samples of the soil and rock at relatively shallow depths underground.

[0003] In the prior art, a patent document with the publication number CN118774771B has emerged. This patent document discloses a rock and soil layer drilling device, including a support and a fixed seat fixedly connected to the top of the support. An auxiliary seat is fixedly connected to the inner side of the fixed seat. A second driving motor is installed at the bottom of the auxiliary seat, and the output end of the second driving motor is connected to a first one-way threaded lead screw, and one end of the first one-way threaded lead screw extends into the inner side of the auxiliary seat and is rotatably connected to the auxiliary seat. By setting a sampling mechanism in this patent document, the output end of the first micro electric push rod pushes the positioning seat to drive the small spiral drill rod to move outward from the large spiral drill rod. At the same time, the output end of the first micro motor drives the small spiral drill rod to rotate, so as to drill and sample the rock and soil layer at a specified position. Since a plurality of small spiral drill rods are arranged at equal distances, it is possible to sample rock and soil layers at different depths, thereby improving the sampling efficiency.

[0004] The above and the prior art have the following defects: During the sampling process using the above device, when it is necessary to obtain multiple samples at the same depth, it is necessary to first move the lowermost small spiral drill rod to the sampling position for sampling. After the sampling is completed, then control the large spiral drill rod to move downward so that other small spiral drill rods move to the sampling position. This process takes a lot of time, and errors are likely to occur during multiple moving adjustments, thereby reducing the sampling accuracy.

[0005] Therefore, a geological soil sampling device for ecological restoration is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that it is difficult for a sampling drill to quickly obtain multiple samples at the same depth, and a geological soil sampling device for ecological restoration is proposed.

[0007] To achieve the above purpose, the present invention adopts the following technical solution: A geological soil sampling device for ecological restoration, including a moving frame, a lead screw is rotatably connected to the surface of the moving frame, a mounting plate is threadedly connected to the outer circumferential surface of the lead screw, and a guide post passing through the mounting plate is fixedly assembled on the surface of the moving frame. It further includes: A sampling structure disposed on the lower surface of the mounting plate for quickly taking multiple samples of geological rock and soil at the same depth. The sampling structure includes a driving gear rotatably mounted on the lower surface of the mounting plate, a plurality of storage tubes for storing rock and soil samples, a plurality of scrapers for scraping rock and soil, a hollow cylinder for drilling soil, and a drill bit. A guiding structure disposed on the inner wall of the hollow cylinder for ensuring that the rock and soil fall into the storage tube. The guiding structure includes a narrowing tube fixedly mounted on the inner wall of the hollow cylinder and a moving tube for inserting into the inner wall of the storage tube. A vibration structure disposed on the inner wall of the hollow cylinder for preventing the rock and soil samples from loosening. The vibration structure includes a first motor fixedly mounted on the inner wall of the hollow cylinder, a first magnet, a second magnet, and a third magnet for vibrating the storage tube.

[0008] The effects achieved by the above components are as follows: By setting the sampling structure, when it is necessary to take rock and soil samples during the ecological restoration process, multiple scrapers can be used in cooperation with the storage tubes to take multiple samples simultaneously, thereby improving the speed of obtaining multiple samples, and further improving the sampling efficiency and sampling accuracy. By setting the guiding structure, when the rock and soil fragments enter the hollow cylinder, it can ensure that the rock and soil fragments accurately enter the storage tube, avoiding the situation of rock and soil fragments spilling. By setting the vibration structure, during the sampling process, under the cooperation of the first magnet, the second magnet, and the third magnet, the storage tube will vibrate continuously in the vertical direction, so that the rock and soil fragments are evenly distributed in the storage tube, making full use of the internal space of the storage tube and improving the practicability.

[0009] Preferably, a driven gear is rotatably connected to the lower surface of the mounting plate. The driven gear meshes with the driving gear. A U-shaped ring is fixedly assembled on the lower surface of the mounting plate. A toothed ring is rotatably connected to the inner wall of the U-shaped ring. The toothed ring meshes with the driven gear. A connecting plate is fixedly assembled on the lower surface of the toothed ring. The connecting plate is fixedly connected to the hollow cylinder. The drill bit is fixedly assembled at the lower end of the hollow cylinder. A cover plate is slidably connected to the outer circumferential surface of the hollow cylinder. A card slot is provided on the surface of the hollow cylinder. A clamping plate is slidably connected in the cover plate. The clamping plate is engaged with the card slot. A partition is fixedly assembled on the inner wall of the hollow cylinder. A sliding rod is slidably connected in the partition. The upper end of the sliding rod is fixedly assembled with a tray. The storage tube is slidably connected to the tray. The scraper is rotatably mounted on the outer circumferential surface of the hollow cylinder. An electric push rod is rotatably connected to the inner wall of the hollow cylinder. The output end of the electric push rod is fixedly assembled with a circular frame. An extension rod is slidably connected to the inner wall of the circular frame. The extension rod is rotatably connected to the scraper. A plurality of the scrapers are located on the same horizontal plane. A plurality of through holes are provided on the circumferential surface of the drill bit. An arched block is fixedly assembled at the position of the drill bit relative to the through hole.

[0010] The effects achieved by the above components are as follows: The driven gear rotates following the driving gear, which drives the tooth ring to rotate along the inner wall of the U-shaped ring. The connecting plate rotates following the tooth ring, which drives the hollow cylinder and the drill bit to rotate. When the drill bit contacts the rock and soil, the arched block will break the rock and soil, and the rock and soil fragments will enter the inner wall of the hollow cylinder through the through holes. When the hollow cylinder moves to an appropriate depth, control the output end of the electric push rod to extend, and the output end of the electric push rod will drive the circular frame to move. When the hollow cylinder drives the scraper to rotate, the scraper will move along the surface of the rock and soil to scrape the rock and soil into pieces, and then the rock and soil fragments will enter the hollow cylinder under the guidance of the scraper, and the storage pipe will collect the rock and soil fragments, thus completing the sampling operation.

[0011] Preferably, a first spring is fixedly assembled on the inner wall of the circular frame, and one end of the first spring is fixedly connected to the extension rod.

[0012] The effects achieved by the above components are as follows: The first spring starts to stretch, and the extension rod will use the elastic force of the first spring to make the scraper press against the surface of the rock and soil.

[0013] Preferably, a rotating shaft is fixedly assembled at the lower end of the driving gear, and an auger is fixedly assembled on the circumferential surface of the rotating shaft, and the auger abuts against the inner circumferential surface of the hollow cylinder.

[0014] The effects achieved by the above components are as follows: The driving gear will drive the rotating shaft to rotate, the rotating shaft will drive the auger to rotate, and the auger will convey the rock and soil fragments upward for discharge, ensuring that the hollow cylinder can move downward normally.

[0015] Preferably, a magnet is fixedly assembled at one end of the clamping plate, and both the hollow cylinder and the cover plate are made of iron.

[0016] The effects achieved by the above components are as follows: The magnet will limit the position of the clamping plate in the clamping groove by means of magnetic force.

[0017] Preferably, the narrowing pipe is located between the scraper and the storage pipe. The lower end of the narrowing pipe is fixedly communicated with a fixed pipe.

A clamping ring sleeved on the outer wall of the storage pipe is fixedly assembled on the outer circumferential surface of the moving pipe. The inner diameters of the fixed pipe, the moving pipe and the storage pipe gradually increase.

[0018] The effects achieved by the above components are as follows: The narrowing pipe will narrow the dispersion range of the rock and soil fragments, facilitating the subsequent collection of the rock and soil fragments. Then the rock and soil fragments will pass through the fixed pipe and the moving pipe and enter the storage pipe. The cooperation of the narrowing pipe, the fixed pipe and the moving pipe can ensure that the rock and soil fragments accurately enter the storage pipe, avoiding the situation of the rock and soil fragments spilling.

[0019] Preferably, a second spring is sleeved on the outer circumferential surface of the fixed pipe, and both ends of the second spring are fixedly connected to the narrowing pipe and the moving pipe respectively.

[0020] The effects achieved by the above components are as follows: when the second spring extends, the moving tube will move downward and insert into the storage tube by the elastic force of the second spring, and prevent the moving tube from being disengaged from the storage tube during the rotation of the hollow cylinder.

[0021] Preferably, a rotating plate is fixedly assembled at the output end of the first motor, the first magnetic block and the second magnetic block are both fixedly installed in the rotating plate, the first magnetic block and the second magnetic block are arranged crosswise, a circular plate is fixedly assembled at the lower end of the sliding rod, the third magnetic block is fixedly installed in the circular plate, the magnetic pole directions of the sides of the first magnetic block and the third magnetic block close to each other are the same, and the magnetic pole directions of the sides of the second magnetic block and the third magnetic block close to each other are opposite.

[0022] The effects achieved by the above components are as follows: when the first motor is turned on, the rotation of the output end of the first motor will drive the rotating plate to rotate, the rotating plate will drive the first magnetic block and the second magnetic block to rotate. When the first magnetic block is aligned with the third magnetic block, since the magnetic pole directions of the sides of the first magnetic block and the third magnetic block close to each other are the same, at this time, the third magnetic block will drive the circular plate to move upward due to the repulsion of the first magnetic block, and the movement of the circular plate will drive the storage tube to move. When the second magnetic block is aligned with the third magnetic block, since the magnetic pole directions of the sides of the second magnetic block and the third magnetic block close to each other are opposite, at this time, the second magnetic block and the third magnetic block will attract each other, and the third magnetic block will drive the circular plate to move in the direction close to the second magnetic block. Therefore, during the continuous operation of the first motor, the storage tube will vibrate continuously in the vertical direction, so that the rock and soil fragments are evenly distributed in the storage tube, the internal space of the storage tube can be fully utilized, and the practicability is improved.

[0023] Preferably, the number of the first magnetic block, the second magnetic block and the third magnetic block is the same or all even numbers.

[0024] The effects achieved by the above components are as follows: by making the number of the first magnetic block, the second magnetic block and the third magnetic block the same or all even numbers, the situation that the third magnetic block is simultaneously aligned with the first magnetic block and the second magnetic block can be avoided, and the rotating plate can be evenly stressed and move.

[0025] Preferably, the sliding rod has a regular hexagonal prism structure.

[0026] The effects achieved by the above components are as follows: the sliding rod with a regular hexagonal prism structure can limit the moving path of the circular plate and prevent the situation that the third magnetic block follows the second magnetic block to rotate after being attracted by the second magnetic block.

[0028] In the present invention, by providing a guiding structure, after the geotechnical fragments enter the hollow cylinder, it can ensure that the geotechnical fragments accurately enter the storage tube, avoiding the situation of geotechnical fragments spilling, and the inner diameters of the fixed tube, the moving tube and the storage tube gradually increase, which can avoid the situation of blockage during the sliding process of the geotechnical fragments.

[0029] In the present invention, by providing a vibration structure, during the sampling process, under the cooperation of the first magnetic block, the second magnetic block and the third magnetic block, the storage tube will continuously vibrate in the vertical direction, so that the geotechnical fragments are evenly distributed in the storage tube, making full use of the internal space of the storage tube and improving the practicability.

A guide post 4 passing through the mounting plate 3 is fixedly assembled on the surface of the moving frame 1. It further includes: a sampling structure arranged on the lower surface of the mounting plate 3 for quickly taking multiple samples of geological and geotechnical materials at the same depth. The sampling structure includes a driving gear 5 rotatably installed on the lower surface of the mounting plate 3, a plurality of storage tubes 16 for storing geotechnical samples, a plurality of scrapers 17 for scraping geotechnical materials, a hollow cylinder 10 for drilling soil, and a drill bit 11; a guiding structure arranged on the inner wall of the hollow cylinder 10 for ensuring that the geotechnical materials fall into the storage tube 16. The guiding structure includes a narrowing tube 27 fixedly installed on the inner wall of the hollow cylinder 10 and a moving tube 29 for inserting into the inner wall of the storage tube 16; a vibration structure arranged on the inner wall of the hollow cylinder 10 for preventing the geotechnical samples from loosening. The vibration structure includes a first motor 33 fixedly installed on the inner wall of the hollow cylinder 10, a first magnet 35, a second magnet 36, and a third magnet 38 for vibrating the storage tube 16.

[0035] As Figures 2-7As shown, a driven gear 6 is rotatably connected to the lower surface of the mounting plate 3. A third motor 41 is fixedly assembled on the upper surface of the mounting plate 3. The output end of the third motor 41 is fixedly connected to the driven gear 6. The driven gear 6 meshes with the driving gear 5. A U-shaped ring 7 is fixedly assembled on the lower surface of the mounting plate 3. A toothed ring 8 is rotatably connected to the inner wall of the U-shaped ring 7. The toothed ring 8 meshes with the driven gear 6. A connecting plate 9 is fixedly assembled on the lower surface of the toothed ring 8. The connecting plate 9 is fixedly connected to the hollow cylinder 10. A drill bit 11 is fixedly assembled at the lower end of the hollow cylinder 10. A cover plate 13 is slidably connected to the outer circumferential surface of the hollow cylinder 10. A card slot 24 is formed on the surface of the hollow cylinder 10. A clamping plate 25 is slidably connected in the cover plate 13. The clamping plate 25 is snap-fitted with the card slot 24. A partition plate 14 is fixedly assembled on the inner wall of the hollow cylinder 10. A sliding rod 15 is slidably connected in the partition plate 14. The upper end of the sliding rod 15 is fixedly assembled with a tray 32. A storage pipe 16 is slidably connected to the tray 32. A scraping plate 17 is rotatably installed on the outer circumferential surface of the hollow cylinder 10. An electric push rod 18 is rotatably connected to the inner wall of the hollow cylinder 10. The output end of the electric push rod 18 is fixedly assembled with a circular frame 19. An extension rod 20 is slidably connected to the inner wall of the circular frame 19. The extension rod 20 is rotatably connected to the scraping plate 17. A plurality of scraping plates 17 are located on the same horizontal plane. A plurality of through holes 12 are formed on the circumferential surface of the drill bit 11. An arched block 39 is fixedly assembled at the position of the drill bit 11 relative to the through hole 12. When the driven gear 6 rotates following the driving gear 5, it will drive the toothed ring 8 to rotate along the inner wall of the U-shaped ring 7. When the connecting plate 9 rotates following the toothed ring 8, it will drive the hollow cylinder 10 and the drill bit 11 to rotate. When the drill bit 11 contacts the rock and soil, the arched block 39 will break the rock and soil. The rock and soil fragments will enter the inner wall of the hollow cylinder 10 through the through holes 12. When the hollow cylinder 10 moves to an appropriate depth, control the output end of the electric push rod 18 to extend. The output end of the electric push rod 18 will drive the circular frame 19 to move. When the hollow cylinder 10 drives the scraping plate 17 to rotate, the scraping plate 17 will move along the surface of the rock and soil to scrape the rock and soil. Then the rock and soil fragments will enter the hollow cylinder 10 under the guidance of the scraping plate 17. The storage pipe 16 will collect the rock and soil fragments, thus completing the sampling operation. A first spring 21 is fixedly assembled on the inner wall of the circular frame 19. One end of the first spring 21 is fixedly connected to the extension rod 20. When the first spring 21 starts to extend, the extension rod 20 will make the scraping plate 17 press against the surface of the rock and soil by means of the elastic force of the first spring 21. A rotating shaft 22 is fixedly assembled at the lower end of the driving gear 5. A screw conveyor 23 is fixedly assembled on the circumferential surface of the rotating shaft 22. The screw conveyor 23 abuts against the inner circumferential surface of the hollow cylinder 10. The driving gear 5 will drive the rotating shaft 22 to rotate. The rotating shaft 22 will drive the screw conveyor 23 to rotate. The screw conveyor 23 will convey the rock and soil fragments upward for discharge, ensuring that the hollow cylinder 10 can move downward normally. One end of the clamping plate 25 is fixedly assembled with a magnet 26. Both the hollow cylinder 10 and the cover plate 13 are made of iron. The magnet 26 will limit the position of the clamping plate 25 in the card slot 24 by means of magnetic force.

[0036] As Figures 8-10As shown, the narrowing tube 27 is located between the scraping plate 17 and the storage tube 16. A fixed tube 28 is fixedly connected to the lower end of the narrowing tube 27. A moving tube 29 is slidably sleeved on the outer circumferential surface of the fixed tube 28. The moving tube 29 is slidably connected to the inner wall of the storage tube 16. A snap ring 30 sleeving the outer wall of the storage tube 16 is fixedly assembled on the outer circumferential surface of the moving tube 29. The inner diameters of the fixed tube 28, the moving tube 29, and the storage tube 16 gradually increase. The narrowing tube 27 can narrow the dispersion range of the rock and soil fragments, facilitating the subsequent collection of the rock and soil fragments. Then, the rock and soil fragments will pass through the fixed tube 28 and the moving tube 29 and enter the storage tube 16. The cooperation of the narrowing tube 27, the fixed tube 28, and the moving tube 29 can ensure that the rock and soil fragments accurately enter the storage tube 16, avoiding the situation of the rock and soil fragments spilling. A second spring 31 is sleeved on the outer circumferential surface of the fixed tube 28. The two ends of the second spring 31 are respectively fixedly connected to the narrowing tube 27 and the moving tube 29. When the second spring 31 extends, the moving tube 29 will move downward by the elastic force of the second spring 31 and insert into the storage tube 16, and prevent the moving tube 29 from being disengaged from the storage tube 16 during the rotation of the hollow cylinder 10.

[0037] As Figure 9 and Figure 10As shown, a rotating plate 34 is fixedly assembled at the output end of the first motor 33. The first magnet 35 and the second magnet 36 are both fixedly installed in the rotating plate 34. The first magnet 35 and the second magnet 36 are arranged crosswise. A circular plate 37 is fixedly assembled at the lower end of the sliding rod 15. The third magnet 38 is fixedly installed in the circular plate 37. The magnetic pole directions of the sides of the first magnet 35 and the third magnet 38 close to each other are the same. The magnetic pole directions of the sides of the second magnet 36 and the third magnet 38 close to each other are opposite. When the first motor 33 is started, the rotation of the output end of the first motor 33 will drive the rotating plate 34 to rotate. The rotating plate 34 will drive the first magnet 35 and the second magnet 36 to rotate. When the first magnet 35 is aligned with the third magnet 38, since the magnetic pole directions of the sides of the first magnet 35 and the third magnet 38 close to each other are the same, at this time, the third magnet 38 will drive the circular plate 37 to move upward due to the repulsion of the first magnet 35. The movement of the circular plate 37 will drive the storage tube 16 to move. When the second magnet 36 is aligned with the third magnet 38, since the magnetic pole directions of the sides of the second magnet 36 and the third magnet 38 close to each other are opposite, at this time, the second magnet 36 and the third magnet 38 will attract each other, and the third magnet 38 will drive the circular plate 37 to move in the direction close to the second magnet 36. Therefore, during the continuous operation of the first motor 33, the storage tube 16 will vibrate continuously in the vertical direction, so that the rock and soil fragments are evenly distributed in the storage tube 16, enabling the internal space of the storage tube 16 to be fully utilized and improving the practicability. The number of the first magnet 35, the second magnet 36, and the third magnet 38 is the same or all even numbers. By making the number of the first magnet 35, the second magnet 36, and the third magnet 38 the same or all even numbers, the situation where the third magnet 38 is simultaneously aligned with the first magnet 35 and the second magnet 36 can be avoided, and the rotating plate 34 can be evenly stressed and move. The sliding rod 15 has a regular hexagonal prism structure. The sliding rod 15 with a regular hexagonal prism structure can limit the movement path of the circular plate 37 and prevent the situation where the third magnet 38 follows the second magnet 36 to rotate after being attracted to the second magnet 36.

[0038] The overall working principle is as follows: When geotechnical sampling is required during the ecological restoration process, the hollow cylinder 10 is moved to the sampling position by means of the mobile frame 1. Then, the output end of the third motor 41 is controlled to rotate. The output end of the third motor 41 will drive the driving gear 5 to rotate. The driven gear 6 will rotate following the driving gear 5 and drive the toothed ring 8 to rotate along the inner wall of the U-shaped ring 7. The connecting plate 9 will rotate following the toothed ring 8 and drive the hollow cylinder 10 and the drill bit 11 to rotate. Then, the output end of the second motor 40 is controlled to rotate. The second motor 40 will drive the lead screw 2 to rotate. The lead screw 2 will drive the mounting plate 3 to move downward by means of the thread. At this time, both the hollow cylinder 10 and the drill bit 11 will move downward synchronously. When the drill bit 11 contacts the geotechnical material, the arched block 39 will break the geotechnical material. The geotechnical fragments will enter the inner wall of the hollow cylinder 10 through the through hole 12. At this time, the driving gear 5 will drive the rotating shaft 22 to rotate. The rotating shaft 22 will drive the auger 23 to rotate. The auger 23 will convey the geotechnical fragments upward for discharge to ensure that the hollow cylinder 10 can move downward normally. When the hollow cylinder 10 moves to an appropriate depth, the output end of the electric push rod 18 is controlled to extend. The output end of the electric push rod 18 will drive the circular frame 19 to move. The circular frame 19 will lose the limit on the extension rod 20. Therefore, the first spring 21 starts to extend. The extension rod 20 will make the scraper 17 press against the surface of the geotechnical material by means of the elastic force of the first spring 21. When the hollow cylinder 10 drives the scraper 17 to rotate, the scraper 17 will move along the surface of the geotechnical material and scrape the geotechnical material. Then, the geotechnical fragments will enter the hollow cylinder 10 under the guidance of the scraper 17. Then, the narrowing pipe 27 will guide the geotechnical fragments. The narrowing pipe 27 will narrow the dispersion range of the geotechnical fragments, facilitating the subsequent collection of the geotechnical fragments. Then, the geotechnical fragments will pass through the fixed pipe 28 and the moving pipe 29 and enter the storage pipe 16. The cooperation of the narrowing pipe 27, the fixed pipe 28 and the moving pipe 29 can ensure that the geotechnical fragments accurately enter the storage pipe 16 and prevent the geotechnical fragments from spilling. The storage pipe 16 will collect the geotechnical fragments, thus completing the sampling operation. During this process, since several scrapers 17 are located on the same horizontal plane, the output ends of multiple electric push rods 18 can be controlled to extend by different lengths at the same time to achieve the operation of sampling simultaneously, thereby greatly improving the sampling efficiency. When sampling is required at different sampling depths, the electric push rod 18 can be controlled to work for sampling after the hollow cylinder 10 moves to an appropriate depth, and an appropriate amount of samples can also be taken by controlling the number of electric push rods 18 working. Therefore, it is more flexible during sampling. On this basis, since the outer circumferential surface of the hollow cylinder 10 can closely adhere to the surrounding geotechnical material, and the geotechnical fragments broken by the drill bit 11 are conveyed upward and discharged from the inner circumferential surface of the hollow cylinder 10, the situation of sample contamination can be avoided.

[0039] During the sampling process, the first motor 33 is turned on. The rotation of the output end of the first motor 33 will drive the rotating plate 34 to rotate. The rotating plate 34 will drive the first magnet 35 and the second magnet 36 to rotate. When the first magnet 35 aligns with the third magnet 38, since the magnetic pole directions of the sides of the first magnet 35 and the third magnet 38 close to each other are the same, at this time, the third magnet 38 will drive the circular plate 37 to move upward due to the repulsion of the first magnet 35. The movement of the circular plate 37 will drive the storage tube 16 to move. At this time, the second spring 31 will be compressed. When the second magnet 36 aligns with the third magnet 38, since the magnetic pole directions of the sides of the second magnet 36 and the third magnet 38 close to each other are opposite, at this time, the second magnet 36 and the third magnet 38 will attract each other, and the third magnet 38 will drive the circular plate 37 to move in the direction close to the second magnet 36. At this time, the storage tube 16 will move downward due to gravity and the elastic force of the second spring 31 to maintain normal contact with the tray 32. Therefore, during the continuous operation of the first motor 33, the storage tube 16 will vibrate continuously in the vertical direction, so that the rock and soil fragments are evenly distributed in the storage tube 16, making the internal space of the storage tube 16 fully utilized, improving the practicability. By making the number of the first magnet 35, the second magnet 36 and the third magnet 38 the same or all even numbers, the situation that the third magnet 38 aligns with the first magnet 35 and the second magnet 36 at the same time can be avoided, and the rotating plate 34 can be evenly stressed and move. The slide bar 15 in the shape of a regular hexagonal prism can limit the movement path of the circular plate 37, preventing the situation that the third magnet 38 follows the second magnet 36 to rotate after being attracted to the second magnet 36.

[0040] After the sampling operation is completed, control the output end of the electric push rod 18 to contract. The electric push rod 18 will drive the circular frame 19 to move. The movement of the circular frame 19 will pull the extension rod 20, and the extension rod 20 will reset the scraper 17 to block the hollow cylinder 10. Then, control the output end of the second motor 40 to rotate in the reverse direction to remove the hollow cylinder 10 from the ground. Then, slide the clamping plate 25 so that the clamping plate 25 slides out from the inner wall of the clamping groove 24. After that, remove the cover plate 13. Then, slide the moving pipe 29 upward along the outer circumferential surface of the fixed pipe 28 so that the moving pipe 29 is disengaged from the storage pipe 16. The second spring 31 will be compressed. Then, the storage pipe 16 can be taken out to transfer or test the rock and soil fragments, ensuring that the ecological restoration operation can proceed normally. When sampling needs to be carried out again, place the clean storage pipe 16 into the tray 32. Then, release the moving pipe 29. At this time, the second spring 31 expands, and the moving pipe 29 will move downward by the elastic force of the second spring 31 and insert into the storage pipe 16. The moving pipe 29 will cause the snap ring 30 to be sleeved on the outer wall of the storage pipe 16. The cooperation between the snap ring 30 and the moving pipe 29 can also prevent the storage pipe 16 from tilting during the rotation of the hollow cylinder 10. After that, slide the cover plate 13 into the hollow cylinder 10. Then, slide the clamping plate 25 so that the clamping plate 25 is inserted into the clamping groove 24. At this time, the magnet 26 will limit the position of the clamping plate 25 in the clamping groove 24 by means of magnetic force. The clamping plate 25 and the clamping groove 24 can limit the position of the cover plate 13. Then, the sampling operation can be continued.
