Description

Technical Field

[0001] The invention belongs to the field of geology, and in particular relates to a mining area moraine sampling device. Background Art

[0002] Glacial till refers to rocks and debris transported and deposited by glaciers, remaining in place after the glaciers melt. Mining in mining areas covered by glacial till using natural caving methods will hollow out the ground, inevitably causing surface subsidence and collapse. Due to the physical properties of glacial till, during the process of ore withdrawal or heavy rainfall-induced subsidence, coarse particles are gradually separated and retained in the soil, while fine particles migrate to the bottom, ultimately leading to underground debris flows.

[0003] In order to study the migration patterns of fine particles in moraine and prevent underground mudslides, it is necessary to sample and test the moraine soil. The sampling methods in the existing technology include soil drilling method, ring knife method, etc., but the problem is that the existing sampling method is to drive the drill bit or ring knife into the soil by applying pressure. The squeezing process inevitably makes the soil too compact, affecting the original basic data of the soil such as particle density and compactness, resulting in the loss of sampling significance and the inability to conduct subsequent research on the migration of fine particles in moraine.

[0004] A sampling device capable of ensuring the original compactness of soil is proposed. Summary of the Invention

[0052] The following describes the implementation of the present invention through specific embodiments. People skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0053] See also Figures 1 to 14. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they have no substantive technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0054] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0055] See also Figures 1 to 3 The present invention provides a mining area moraine sampling device, the device comprising a main cylinder 1, and installed in the main cylinder 1:

[0056] A sampling cartridge storage unit, wherein a plurality of sampling cartridges 501 are mounted in the sampling cartridge storage unit;

[0057] A cartridge cover storage unit, wherein the cartridge cover storage unit is composed of a plurality of cartridge covers 506 for stacking and storing;

[0058] A sampling unit, which is used to clamp the sampling tube 501 for sampling;

[0059] The bottom end face of the main cylinder body 1 is open, and an outer ring 103 is rotatably installed at the end face. The outer ring 103 is coaxial with the main cylinder body 1, and an inner ring 104 is provided at the center of the outer ring 103. The horizontal height of the inner ring 104 is lower than that of the outer ring 103. A plurality of plowshares 105 are fixed between the outer circumferential wall of the inner ring 104 and the bottom end face of the outer ring 103. The plowshares 105 are used to dig the soil between the outer ring 103 and the inner ring 104 to the outside of the outer ring 103. The plowshares 105 have a helix angle.

[0060] In this embodiment, the Pulang copper mine in Diqing, Yunnan, is covered with thick moraine. Because the caving mining method is used, underground debris flows often occur due to heavy rainfall. In order to study the laws of fine particle migration of moraine and reveal the migration characteristics of fine particles during the formation of underground debris flows, it is necessary to take soil samples from various parts of the mining area and measure basic physical indicators such as moisture content, particle density, and compactness of moraine in different areas of the study area. However, the sampling area should not be squeezed too much during sampling, otherwise the accuracy of the sampled soil will be lost.

[0061] The staff picked up the present invention, and the handles were set on both sides of the main cylinder 1. The main cylinder 1 was inserted into the area to be sampled, and the outer ring 103 was driven to rotate at the same time. The outer ring 103 drove the inner ring 104 and the plow 105 to rotate. The inner ring 104 first touched the ground, and the plow 105 was at an angle to the ground. The plow 105 dug the soil to the surroundings and rotated to dig out an inverted trapezoidal annular groove. (The side wall angle of the inverted trapezoidal annular groove is the same as the angle of the plow 105. The outer ring 103 can be removed from the main cylinder 1. By replacing the plow 105 with different angles, it is suitable for different soil types that are loose or compact.) The soil on the inner side of the inner ring is not excavated, forming a soil column. The sampling unit clamps the sampling cylinder 501, and the sampling cylinder 501 covers the soil column from top to bottom. The cylinder cover 506 cuts the soil column horizontally, and then the cylinder cover 506 closes the bottom end of the sampling cylinder 501 to complete the sampling.

[0062] The present invention can assist in sampling, dig a ring groove in the sampling area, and form a soil column in the middle to avoid the soil sample being squeezed during sampling, resulting in distortion of basic data such as particle density and compactness of the soil sample, and loss of sampling significance.

[0063] See also Figures 4 to 6 The axis of the main cylinder body 1 is perpendicular to the ground. An upper cylinder chamber 101 and a lower cylinder chamber 102 are opened in the main cylinder body 1 from top to bottom, and the upper cylinder chamber 101 and the lower cylinder chamber 102 are connected.

[0064] In this embodiment, the sampling unit and the sampling cartridge storage unit are installed in the upper cartridge chamber 101 , the cartridge cover storage unit and the cartridge cover transmission unit are installed in the lower cartridge chamber 102 , and the sampling unit can extend from the upper cartridge chamber 101 to the lower cartridge chamber 102 .

[0065] See also Figures 4 to 7 The sampling tube storage unit includes a central column 201, a sliding groove 202, a storage column 203, a storage groove 204, a hanging platform 205, a positioning boss 206, a gear ring 207, a first rotation power source 208 and a first gear 209;

[0066] A center column 201 is fixedly connected to the center position of the top wall of the upper cylinder chamber 101. The center column 201 is coaxial with the main cylinder body 1. A sliding groove 202 for the sampling unit to slide up and down is provided on the circumferential outer wall of the center column 201. The sliding groove 202 is parallel to the axis of the center column 201. A storage column 203 is rotatably sleeved on the circumferential outer wall of the center column 201. A plurality of storage grooves 204 are evenly provided on the circumferential inner wall of the storage column 203 around the axis. The length direction of the storage grooves 204 is parallel to the sliding groove 202. The storage grooves 204 are connected to the sliding groove 202. Hanging platforms 205 for clamping the sampling cylinder 501 are fixed in the storage grooves 204. Positioning bosses 206 are fixed on the hanging platforms 205 to prevent the sampling cylinder 501 from rotating.

[0067] A gear ring 207 is fixedly connected to the end face of the storage column 203 , a first rotational power source 208 is mounted on the inner wall of the upper cylinder chamber 101 , a first gear 209 is fixedly connected to the output shaft of the first rotational power source 208 , and the first gear 209 is meshed with the gear ring 207 .

[0068] In this embodiment, the first rotating power source 208 drives the first gear 209 to rotate, and the first gear 209 drives the storage column 203 to rotate. When the storage column 203 rotates, several storage slots 204 are aligned with the sliding slot 202 in sequence, and the sampling unit can pull the sampling tube 501 in the storage slot 204 into the sliding slot 202, and then clamp the sampling tube 501 to slide up and down in the sliding slot 202.

[0069] See also Figure 8 and Figure 9 The device further includes a cylinder cover transmission unit, which includes a left slide rail 301, a right slide rail 302, a slide 303, a pulley 304, a guide slope 305, a placement groove 306 and a second positioning boss 307;

[0070] The left slide rail 301 and the right slide rail 302 are parallel to each other and are both fixedly connected to the inner wall of the lower cylinder chamber 102. The length directions of the left slide rail 301 and the right slide rail 302 are both parallel to the ground. The left slide rail 301 and the right slide rail 302 are located above the inner ring 104 and are respectively located on both sides of the inner ring 104. The two ends of the slide 303 are respectively located on the left slide rail 301 and the right slide rail 302, and are both equipped with pulleys 304. A guide inclined surface 305 is provided on one side of the sliding direction of the slide 303. A placement groove 306 for placing the cylinder cover 506 is provided on the top surface of the slide 303. A second positioning boss 307 is fixedly connected to the inner side wall of the placement groove 306 to prevent the cylinder cover 506 from rotating.

[0071] In this embodiment, the slide 303 can slide back and forth on the left slide rail 301 and the right slide rail 302. When digging the annular groove, the slide 303 is located below the first cylinder 401, and the slide 303 pushes the limit bar 406 to open, and the bottom cylinder cover 506 falls into the placement groove 306. The depth of the placement groove 306 is consistent with the height of the cylinder cover 506.

[0072] When a soil column is formed by excavation, the sampling unit carries the sampling tube 501 to cover the outer circle of the soil column, and the slide 303 carries the tube cover 506 to slide toward the soil column. The guide slope 305 of the slide cuts off the soil column, and then the tube cover 506 quickly moves to the bottom of the sampling tube 501. The tube cover 506 blocks the soil column that has entered the sampling tube 501 above in the sampling tube 501. The sampling unit drives the sampling tube 501 to rotate and screws the tube cover 506 closed.

[0073] See also Figure 8 、 Figure 10 and Figure 11 , the device also includes a cylinder cover storage unit, the cylinder cover storage unit includes a first cylinder 401, a third positioning boss 402, a mounting seat 403, a rotating shaft 404, a torsion spring 405 and a limiting strip 406;

The axis of the first cylinder 401 is perpendicular to the ground. Several cylinder covers 506 are stacked inside the first cylinder 401. A third positioning boss 402 is fixed to the inner wall of the first cylinder 401 to prevent the cylinder covers 506 from rotating. The length of the third positioning boss 402 is parallel to the axis of the first cylinder 401.

[0075] The bottom surface of the first cylinder 401 is open, and the bottom end surface of the first cylinder 401 is flush with the top surface of the slide 303. Two mounting seats 403 are fixedly connected to the outer wall of the first cylinder 401 on the side away from the slide 303. The two mounting seats 403 are symmetrically arranged with the sliding track of the slide 303 as the central axis. A rotating shaft 404 is installed on each of the mounting seats 403. The axis of the rotating shaft 404 is parallel to the first cylinder 401. The two rotating shafts 404 are sleeved with a torsion spring 404. 5. One end of the torsion spring 405 is fixedly connected to the mounting seat 403, and the other end is fixedly connected to the rotating shaft 404. The other ends of the two rotating shafts 404 extend to the bottom surface of the first cylinder 401, and the outer circumferential walls are fixedly connected with limit bars 406. The length direction of the two limit bars 406 is perpendicular to the axis of the first cylinder 401. The two limit bars 406 block the bottom surface of the first cylinder 401.

[0076] In this embodiment, a plurality of cylinder covers 506 are stacked and stored in the first cylinder 401. The cylinder covers 506 are blocked by the limiting bars 406 and will not fall out. When the slide 303 slides under the first cylinder 401, the slide 303 pushes the limiting bars 406 to the sides, the rotating shaft 404 rotates, and the torsion spring 405 is compressed.

[0077] The bottom cylinder cover 506 falls into the placement groove 306 of the slide 303, while the rest are blocked in the first cylinder 401. As the slide 303 gradually slides away, the limit bar 406 gradually swings back to its original position, supporting the remaining cylinder covers 506 above and blocking them in the first cylinder 401.

[0078] See also Figure 12The sampling tube 501 is closed at the top and open at the bottom. A ring platform 502 that cooperates with the hanging platform 205 is fixedly connected to the circumferential outer wall of the sampling tube 501.

[0085] Push the ring sleeve 603 again to push the ring sleeve 603 back to the direction of the sliding groove 202. The lifting column 606 brings the sampling barrel 501 back into the sliding groove 202, and pushes the lifting column 606 down. The lifting column 606 drives the sampling barrel 501 down and extends into the lower barrel chamber 102, covering the soil column to be sampled. The barrel cover transmission unit cuts off the soil column and transmits the barrel cover 506 to the bottom of the sampling barrel 501. The second rotary power source 608 is started again, driving the threaded barrel 609 to rotate, and screwing the sampling barrel 501 and the barrel cover 506 together.

[0086] Then, the lifting column 606 is pulled upward, and after aligning any empty storage slot 204 with the sliding slot 202, the ring sleeve 603 is pushed into the storage slot 204, and the sampling barrel 501 is clamped into the storage slot 204. The second rotary power source 608 is started in the reverse direction. Because the positioning notch 503 of the sampling barrel 501 cooperates with the positioning boss 206, the sampling barrel 501 cannot rotate. The threaded barrel 609 is unscrewed from the sampling barrel 501, and the ring sleeve 603 and the lifting column 606 are pulled back into the sliding slot 202;

[0087] Finally, the storage column 203 is rotated to turn the storage slot 204 away from the sliding slot 202, so that the sampling tube 501 after sampling is stuck and will not fall out.

[0088] See also Figure 3 A second gear ring 106 is fixedly connected to the inner wall of the outer ring 103, a third rotational power source 107 is installed on the inner wall of the lower cylinder chamber 102, a second gear 108 is fixedly connected to the output shaft of the third rotational power source 107, and the second gear 108 is engaged with the second gear ring 106.

[0089] In this embodiment, the third rotational power source 107 drives the second gear 108 , and the second gear 108 drives the outer ring 103 to rotate.

[0090] See also Figure 12 The bottom edge of the cylinder cover 506 is provided with a chamfer 509 that cooperates with the limiting strip 406.

[0091] In this embodiment, when the slide 303 leaves, the limit bar 406 swings back to its original position, and the limit bar 406 contacts the chamfer 509 , thereby better separating the remaining cylinder cover 506 from the cylinder cover that falls out below, and blocking the remaining cylinder cover 506 in the first cylinder 401 .

[0092] See also Figure 9 A plurality of soil leakage holes 308 are provided at the bottom of the placement groove 306 .

[0093] In this embodiment, when the slide 303 cuts off the soil column, soil may fall into the placement groove 306 and affect the placement of the next cylinder cover 506. The soil leakage hole 308 can prevent the soil from accumulating in the placement groove 306.

[0094] The usage process of this device is:

[0095] First, the main cylinder 1 is inserted into the area to be sampled, and the outer ring 103 is driven to rotate. The outer ring 103 drives the inner ring 104 and the plow 105 to rotate. The plow 105 plows the soil to the surrounding area and rotates to dig a hole. The soil inside the inner ring is not excavated, forming a soil column.

[0096] Then, the storage column 203 is driven to rotate, and any storage slot 204 equipped with the sampling barrel 501 is aligned with the sliding slot 202. The ring sleeve 603 is pushed in the direction of the storage slot 204. The ring sleeve 603 can slide the lifting column 606 into the storage slot 204, pulling the lifting column 606 up. The threaded barrel 609 on the bottom surface of the lifting column 606 is aligned with the top of the sampling barrel 501. The second rotational power source 608 is started, driving the threaded barrel 609 to rotate, screwing the sampling barrel 501 into the threaded barrel 609;

[0097] Then, the ring 603 is pulled back to the direction of the sliding groove 202, and the lifting column 606 brings the sampling tube 501 back into the sliding groove 202. Then, the lifting column 606 is pushed down, and the lifting column 606 brings the sampling tube 501 down, covering the sampling tube 501 on the soil column. The lowest descending position of the sampling tube 501 will not be lower than the slide 303.

[0098] Then, after the slide 303 receives the cylinder cover 506 from the first cylinder 401, the slide 303 slides toward the soil column with the cylinder cover 506, and the guide inclined surface 305 of the slide cuts off the soil column. Then, the cylinder cover 506 quickly moves to the bottom of the sampling cylinder 501, and the cylinder cover 506 blocks the soil column that has entered the sampling cylinder 501 inside the sampling cylinder 501. The second rotary power source 608 is started, driving the threaded cylinder 609 to rotate, and the threaded cylinder 609 drives the sampling cylinder 501 to rotate, and the sampling cylinder 501 is screwed together with the cylinder cover 506.

[0099] Then, the lifting column 606 is pulled up to drive the storage column 203 to rotate, and an empty storage slot 204 is rotated to align with the sliding slot 202. The ring sleeve 603 is pushed in the direction of the storage slot 204. The ring sleeve 603, carrying the lifting column 606 and the sampling barrel 501 with the sampling completed, slides into the storage slot 204. The second rotary power source 608 is started in the reverse direction. Because the positioning notch 503 of the sampling barrel 501 cooperates with the positioning boss 206, the sampling barrel 501 cannot rotate, and the threaded barrel 609 is unscrewed from the sampling barrel 501.

[0100] Finally, the ring sleeve 603 is pulled back to the direction of the sliding slot 202, and the lifting column 606 is also returned to the sliding slot 202. The storage column 203 is rotated to turn the storage slot 204 away from the sliding slot 202, so that the sampling tube 501 with completed sampling is stuck and will not fall out.
