Description

Technical Field

[0001] The invention belongs to the technical field of geological sampling and detection, and particularly relates to a rotary cutting sampling component and a sampling method for geological mineral resource exploration. Background Art

[0002] The exploration of geological and mineral resources is a complex and high-risk task. During the mineral resource exploration stage, it is necessary to test the shallow surface and understand the composition, structure and properties of the shallow surface soil. Mining activities may cause pollution to the surrounding soil, such as heavy metal pollution. By testing the shallow surface soil, it is possible to assess in advance the impact that mining activities may have on the soil environment, including changes in soil fertility and the extent to which vegetation growth is affected.

[0003] In the existing geological and mineral resource exploration, in addition to using large equipment to sample and test deep underground, sampling of shallow surface layers is mostly done by drilling or shoveling. Small equipment has a limited sampling depth for underground. At the same time, when encountering hard soil layers or sand and gravel, the equipment will collide and easily cause damage, which is inconvenient to use. In addition, it is difficult to intuitively display soil samples at different depths, which is inconvenient to use.

[0004] Based on the above-mentioned situation, we found that it is difficult for the existing technology of geological and mineral resource exploration rotary cutting sampling components to avoid the above problems at the same time. Therefore, we proposed a method that can effectively extend the sampling depth of small equipment and improve the stability during sampling, ensure the relative level of sampling, and not easily cause damage when encountering hard soil samples. It can also intuitively display soil samples at different depths. A rotary cutting sampling component and sampling method for geological and mineral resource exploration. Summary of the invention

[0005] The purpose of the present invention is to target an existing rotary cutting sampling component and sampling method for geological and mineral resource exploration. The advantages of the present invention are that the sampling depth of small equipment can be effectively extended, the stability during sampling can be improved, the relative level of sampling can be ensured, and it is not easy to cause damage when encountering hard soil samples. Soil samples at different depths can be displayed intuitively.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a rotary cutting sampling component for geological mineral resource exploration, comprising a structural plate, the bottom of the structural plate is rotatably connected to a tripod, the inner side of the structural plate is movably connected to a connecting frame, the bottom of the connecting frame is bolted to a limiting frame, the inner side of the limiting frame is bolted to a driving motor, the output end of the driving motor is bolted to a crankshaft, and the bottom of the crankshaft is rotatably connected to a drilling device;

[0007] The lower drilling device comprises an upper shell, the inner side of the upper shell is slidably connected to the bottom of the limit frame, the inner side of the upper shell is bolted with a reduction motor, the output end of the reduction motor is bolted with a rotary cutting structure, the outer side of the rotary cutting structure is fixedly connected with an assembly frame, the outer side of the rotary cutting structure is provided with a sample cylinder, and the inner side of the sample cylinder is movably connected with a clamping ring;

[0008] A slide is bolted to the top of the structural plate, the inner side of the slide is slidably connected to the connecting frame, an extension rod is provided on the top of the connecting frame, a first screw hole is provided on the top of the extension rod and the top of the connecting frame, a screw is fixedly connected to the bottom of the extension rod, a pressure frame is provided on the inner side of the extension rod, and a pressure plate is fixedly connected to the right side of the pressure frame.

[0009] By adopting the above technical scheme, by setting a tripod in conjunction with the structural plate, the structure can be placed stably on the sampling ground, and the driving motor in conjunction with the crankshaft can drive the bottom drilling device to perform reciprocating vertical activities. Under the limit of the limit frame and the upper shell, the upper shell and the bottom structure will perform reciprocating linear motion. The reduction motor is used to drive the rotary cutting structure to perform rotary cutting. The upper and lower knives of the rotary cutting structure cooperate with the knife shaft, which will break up the soil layer and place it into the interior of the sample tube when rotating. When the single sampling depth is consistent with the length of the sample tube, it can be taken out, and the internal sample is retained according to the depth of the soil layer, which can facilitate convenient observation of the sample. When encountering hard soil layers or sand and gravel, the knife shaft collides with the upper knife or the lower knife. However, the slide rod will retract into the interior of the connecting tube, and has a certain buffer space, which can reduce the damage to the structure. When the samples attached to the surface of the knife shaft, the upper knife and the lower knife are difficult to remove, the knocking plate can be knocked, and the knife shaft and the lower knife move downward together. When the knife shaft moves, the rectangular plate and the slide rod fall at the same time, but the rectangular plate will push the fluid medium inside the inner tube to flow and be buffered. Therefore, the displacement of the lower knife will be greater. When the lower knife and the knife shaft are vibrated respectively, the attached samples will be shaken off. By setting a slide frame in conjunction with the connecting frame, the bottom structure can be easily connected. The set extension rod can be flexibly assembled according to the required sampling depth. At the same time, the pressure frame connected to it cooperates with the pressure plate to press down to provide pressure, so that the bottom structure can drill downward stably.

[0010] The present invention is further configured as follows: the rotary cutting structure includes a connecting tube, a sliding rod is provided on the inner side of the connecting tube, a knife shaft is bolted to the bottom of the sliding rod, an upper knife is fixedly connected to the outer side of the knife shaft, and a lower knife is installed at the bottom of the upper knife.

[0011] By adopting the above technical solution, by setting a connecting tube and a sliding rod, the knife shaft can generate a certain displacement space for buffering when it is impacted or hit. The upper knife and the lower knife form a sampling blade, which can move to a certain extent when needed without affecting normal sampling.

[0012] The present invention is further configured as follows: a hard tension spring is bolted to the bottom of the upper knife, the bottom of the hard tension spring is fixedly connected to the lower knife, and a knocking piece is fixedly connected to the top of the lower knife.

[0013] By adopting the above technical solution, a knocking plate is provided, and when struck, the lower knife will be displaced along the knife axis relative to the upper knife. The hard tension spring is provided to pull the upper and lower knives to reset when they are displaced.

[0014] The present invention is further configured as follows: a second screw hole is provided on the inner side of the clamping ring, a bolt is provided on the inner side of the assembly frame, the bolt passes through the assembly frame and the sample tube and is threadedly connected with the second screw hole.

[0015] By adopting the above technical solution, by providing the second screw hole and the matching bolt, the sample tube can be stably connected or quickly disassembled, so as to facilitate the replacement of different sample tubes and separate storage of different samples.

[0016] The present invention is further configured as follows: an inner cylinder is bolted to the inner side of the connecting cylinder, and the inner cylinder and the inner top and bottom of the inner side of the inner cylinder are both provided with flow holes.

[0017] By adopting the above technical solution, an inner cylinder is provided to cooperate with the flow hole, and the flow hole is used to supply the internal fluid medium to flow. The provided inner cylinder can be conveniently provided to the sliding position of the slide rod.

[0018] The present invention is further configured as follows: a hard spring is bolted to the top of the inner wall of the connecting tube, a rectangular sheet is fixedly connected to the bottom of the hard spring, the bottom of the rectangular sheet is fixedly connected to the sliding rod, and the inner side of the connecting tube is filled with a fluid medium.

[0019] By adopting the above technical solution, a rectangular sheet is arranged to cooperate with the flow hole. When the rectangular sheet moves along the inside of the inner tube, it will push the internal fluid medium to flow along the flow hole to achieve a damping effect. After the movement, the hard spring that is deformed rebounds to push the structure to reset.

[0020] The present invention is further configured as follows: a placement plate is rotatably connected to the bottom of the tripod, and a stabilizing cone is installed at the bottom of the placement plate.

[0021] By adopting the above technical solution, by setting a placement plate, the skeleton can be stabilized when in contact with the ground, and the set stabilizing cone inserted into the ground can prevent the structure from loosening or displacement.

[0022] The present invention is further configured as follows: a mounting tube is fixedly connected to the outer side of the tripod, connecting rods are bolted to the outer sides of the two mounting tubes on the right side, a limiting frame is fixedly connected to the side of the connecting rod away from the mounting tube, and a matching frame is provided on the inner side of the limiting frame.

[0023] By adopting the above technical solution, by setting the installation tube to cooperate with the connecting rod, it is easy to cooperate with the limit frame and the matching frame, and the sample cylinder can be initially limited when it is installed, and shaking can be avoided when it is initially drilled.

[0024] The present invention is further configured as follows: a pin rod is inserted into the inner side of the limit frame, and the outer side of the pin rod is inserted into the matching frame.

[0025] By adopting the above technical solution, the matching frame and the limiting frame can be quickly connected or disassembled by setting the pin rod, so as to improve the replacement efficiency of the structure.

[0026] The present invention is further configured as: a sampling method for a rotary cutting sampling member for geological mineral resource exploration, comprising the following steps:

[0027] S1. First, unfold the tripod along the structural plate, and insert it into the ground through the stabilizing cone, place the plate in contact with the ground, select the corresponding number of extension rods according to the underground depth required for sampling, and assemble them through the first screw hole and the screw rod, and install the bottom extension rod and the connecting frame;

[0028] S2. A set of sample tubes are clamped on the outside of the clamping ring, and the hole on the top is aligned with the second screw hole, and then the assembly frame is clamped on the top of the sample tube, and the assembly of the structure is completed by screwing the bolt into the second screw hole;

[0029] S3. The reduction motor drives the rotary cutting structure to rotate, and the driving motor drives the crankshaft to rotate. When the crankshaft rotates, it will repeatedly push and pull the upper shell and the bottom structure to reciprocate and vertically lift. The upper shell is restricted by the limit frame and will not swing, but will only reciprocate in a straight line. When a person applies a heavy object through the pressure frame or directly steps on it, it will push the lower drilling device to feed;

[0030] S4. The upper and lower knives of the rotary cutting structure cooperate with the knife shaft to break up the soil layer and place it inside the sample tube when rotating. When the single sampling depth is consistent with the length of the sample tube, it can be taken out and the internal sample is retained. Then the sample tube is replaced and installed, and the sampling is repeated;

[0031] S5. When the samples attached to the surface of the knife shaft, upper knife and lower knife are difficult to remove, the knocking piece can be knocked, and the knife shaft and the lower knife move downward together. When the knife shaft moves, the rectangular piece and the slide rod fall at the same time, but the rectangular piece will push the fluid medium inside the inner tube to flow and be buffered, so the displacement of the lower knife will be greater, and the attached samples will be shaken off when the lower knife and the knife shaft are shaken separately.

[0032] In summary, the present invention has the following beneficial effects:

[0033] By setting the upper and lower knives of the rotary cutting structure in conjunction with the knife shaft, the soil layer will be broken up and placed inside the sample tube when rotating, and it can be taken out when the single sampling depth is consistent with the length of the sample tube, and the internal sample is retained according to the soil layer depth, which can facilitate convenient observation of the sample. The rotary cutting structure moves back and forth while drilling, and the feed position can be repeatedly scraped, so that the inside of the sampling hole is relatively smooth, and subsequent drilling is more labor-saving. When encountering hard soil layers or sand and gravel, the knife shaft collides with the upper or lower knife, but the sliding rod will retract into the interior of the connecting tube, with a certain buffer space, which can reduce damage to the structure. The set extension rod can be flexibly assembled according to the required sampling depth, and at the same time, the pressure frame connected to it cooperates with the pressure plate to press down to provide pressure, so that the bottom structure can drill downward stably.

DETAILED DESCRIPTION

[0044] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0045] Embodiment 1:

[0046] refer to Figure 1-8 A rotary cutting sampling component for geological mineral resource exploration comprises a structural plate 1, a tripod 2 is rotatably connected to the bottom of the structural plate 1, a connecting frame 3 is movably connected to the inner side of the structural plate 1, a limiting frame 4 is bolted to the bottom of the connecting frame 3, a driving motor 5 is bolted to the inner side of the limiting frame 4, a crankshaft 6 is bolted to the output end of the driving motor 5, and a drilling device 7 is rotatably connected to the bottom of the crankshaft 6;

[0047] The lower drilling device 7 includes an upper shell 701, the inner side of the upper shell 701 is slidably connected to the bottom of the limit frame 4, the inner side of the upper shell 701 is bolted with a reduction motor 702, the output end of the reduction motor 702 is bolted with a rotary cutting structure 703, the outer side of the rotary cutting structure 703 is fixedly connected with an assembly frame 704, the outer side of the rotary cutting structure 703 is provided with a sample cylinder 706, and the inner side of the sample cylinder 706 is movably connected with a clamping ring 705;

[0048] By setting a tripod 2 in conjunction with the structural plate 1, the structure can be placed stably on the sampling ground, and the driving motor 5 in conjunction with the crankshaft 6 can drive the bottom drilling device 7 to perform reciprocating vertical activities. Under the limit of the limit frame 4 and the upper shell 701, the upper shell 701 and the bottom structure will perform reciprocating linear motion. The reduction motor 702 is used to drive the rotary cutting structure 703 to perform rotary cutting. The upper knife 703d and the lower knife 703e of the rotary cutting structure 703 cooperate with the knife shaft 703c. When rotating, the soil layer will be broken and placed in the sample tube 706. When the single sampling depth is consistent with the length of the sample tube 706, it can be taken out, and the internal sample is retained according to the soil layer depth, which can facilitate convenient observation of the sample. When encountering hard When the knife shaft 703c is used to remove the sample attached to the surface of the knife shaft 703c, the upper knife 703d and the lower knife 703e, the knocking piece 15 can be knocked, and the knife shaft 703c and the lower knife 703e move downward together. When the knife shaft 703c moves, the rectangular piece 20 and the slide bar 703b fall at the same time, but the rectangular piece 20 will promote the fluid medium inside the inner tube 18 to circulate and be buffered. Therefore, the displacement of the lower knife 703e will be greater, and the attached sample will be shaken off when the lower knife 703e and the knife shaft 703c are shaken respectively.

[0049] like Figure 5 As shown, the rotary cutting structure 703 includes a connecting tube 703a, a sliding rod 703b is provided on the inner side of the connecting tube 703a, a knife shaft 703c is bolted to the bottom of the sliding rod 703b, an upper knife 703d is fixedly connected to the outer side of the knife shaft 703c, and a lower knife 703e is installed on the bottom of the upper knife 703d. By arranging the connecting tube 703a to cooperate with the sliding rod 703b, the knife shaft 703c can generate a certain displacement space for buffering when it is impacted or hit. The upper knife 703d and the lower knife 703e form a sampling blade, which can move to a certain extent when needed without affecting normal sampling.

[0050] like Figure 5 As shown, the bottom of the upper knife 703d is bolted with a hard tension spring 14, the bottom of the hard tension spring 14 is fixedly connected to the lower knife 703e, and the top of the lower knife 703e is fixedly connected with a knocking plate 15. By setting the knocking plate 15, when the lower knife 703e is knocked, it will be displaced along the knife axis 703c relative to the upper knife 703d. The hard tension spring 14 will pull the upper knife 703d and the lower knife 703e to reset when they are displaced.

[0051] like Figure 3 and Figure 4 As shown, a second screw hole 16 is provided on the inner side of the clamping ring 705, and a bolt 17 is provided on the inner side of the assembly frame 704. The bolt 17 passes through the assembly frame 704 and the sample tube 706 and is threadedly connected to the second screw hole 16. By providing the second screw hole 16 and the bolt 17, the sample tube 706 can be firmly connected or quickly disassembled, so as to facilitate the replacement of different sample tubes 706 and store different samples separately.

[0052] like Figure 5 As shown, the inner side of the connecting tube 703a is bolted with an inner tube 18, and the inner tube 18 has flow holes at the top and bottom of the inner side. The inner tube 18 is arranged to cooperate with the flow holes, and the flow holes are used to supply the internal fluid medium to flow. The inner tube 18 can be easily provided to the sliding position of the slide rod 703b.

[0053] like Figure 6 As shown, a hard spring 19 is bolted to the top of the inner wall of the connecting tube 703a, and a rectangular sheet 20 is fixedly connected to the bottom of the hard spring 19. The bottom of the rectangular sheet 20 is fixedly connected to the slide rod 703b, and the inner side of the connecting tube 703a is filled with a fluid medium. By setting the rectangular sheet 20 to cooperate with the flow hole, when the rectangular sheet 20 moves along the inside of the inner tube 18, it will push the internal fluid medium to flow along the flow hole to achieve a damping and buffering effect. The hard spring 19 that is deformed after movement will rebound to push the structure to reset.

[0054] Brief description of the usage process: First, install the sample tube 706 on the outside of the clamping ring 705, align the hole on its top with the second screw hole 16, then clamp the assembly frame 704 on the top of the sample tube 706, and screw the bolt 17 into the second screw hole 16 to complete the assembly of the structure. The reduction motor 702 drives the rotary cutting structure 703 to rotate, and the driving motor 5 drives the crankshaft 6 to rotate. When the crankshaft 6 rotates, it will repeatedly push and pull the upper shell 701 and the bottom structure to reciprocate and vertically lift. The upper knife 703d and the lower knife 703e of the rotary cutting structure 703 cooperate with the knife shaft 703c. When rotating, the soil layer will be broken and placed in the interior of the sample tube 706, and the single sampling depth and sample When the length of the tube 706 is consistent, it can be taken out and the internal sample can be retained. Then the sample tube 706 can be replaced and installed, and the sampling can be repeated. When the sample attached to the surface of the knife shaft 703c, the upper knife 703d and the lower knife 703e is difficult to remove, the knocking piece 15 can be knocked, and the knife shaft 703c and the lower knife 703e move downward together. When the knife shaft 703c moves, the rectangular piece 20 and the slide bar 703b fall at the same time, but the rectangular piece 20 will promote the flow of the fluid medium inside the inner tube 18 and be buffered. Therefore, the displacement of the lower knife 703e will be larger. When the lower knife 703e and the knife shaft 703c are shaken respectively, the attached sample will be shaken off to facilitate the subsequent sampling action.

[0055] Embodiment 2:

[0056] refer to Figure 1-8 A rotary cutting sampling component for geological mineral resource exploration comprises a structural plate 1, a tripod 2 is rotatably connected to the bottom of the structural plate 1, a connecting frame 3 is movably connected to the inner side of the structural plate 1, a limiting frame 4 is bolted to the bottom of the connecting frame 3, a driving motor 5 is bolted to the inner side of the limiting frame 4, a crankshaft 6 is bolted to the output end of the driving motor 5, and a drilling device 7 is rotatably connected to the bottom of the crankshaft 6;

[0057] The top of the structural plate 1 is bolted with a slide 8, the inner side of the slide 8 is slidably connected to the connecting frame 3, the top of the connecting frame 3 is provided with an extension rod 9, the tops of the extension rod 9 and the connecting frame 3 are both provided with a first screw hole 10, the bottom of the extension rod 9 is fixedly connected with a screw rod 11, the inner side of the extension rod 9 is provided with a pressure frame 12, and the right side of the pressure frame 12 is fixedly connected with a pressure plate 13;

[0058] When in use, the tripod 2 is unfolded along the structural plate 1 and placed firmly. According to the underground depth required for sampling, the corresponding number of extension rods 9 are selected and assembled through the first screw hole 10 and the screw rod 11, and the bottom extension rods 9 and the connecting frame 3 are installed. The slide 8 connects the extension rods 9 and the connecting frame 3. By setting the slide 8 in conjunction with the connecting frame 3, it is convenient to connect the bottom structure. The set extension rods 9 can be flexibly assembled according to the required sampling depth. At the same time, the pressure frame 12 connected thereto cooperates with the pressure plate 13 to press down to provide pressure, so that the bottom structure can be drilled downward stably.

[0059] like Figure 8 As shown, the bottom of the tripod 2 is rotatably connected to a placement plate 21, and a stabilizing cone 22 is installed at the bottom of the placement plate 21. By setting the placement plate 21, the skeleton can be stabilized when in contact with the ground, and the stabilizing cone 22 is inserted into the ground to prevent the structure from loosening or displacement.

[0060] like Figure 8 As shown, the outer side of the tripod 2 is fixedly connected with a mounting tube 23, and the outer sides of the two mounting tubes 23 on the right are bolted with connecting rods 24. The side of the connecting rod 24 away from the mounting tube 23 is fixedly connected with a limit frame 25, and a matching frame 26 is provided on the inner side of the limit frame 25. By arranging the mounting tube 23 to match the connecting rod 24, it is convenient to match the limit frame 25 and the matching frame 26, so that the sample tube 706 can be initially limited when it is installed, and shaking can be avoided when the initial drilling is carried out.

[0061] like Figure 8As shown, a pin rod 27 is inserted into the inner side of the limit frame 25, and the outer side of the pin rod 27 is inserted into the matching frame 26. By setting the pin rod 27, the matching frame 26 and the limit frame 25 can be quickly connected or disassembled, so as to improve the replacement efficiency of the structure.

[0062] Brief description of the usage process: When in use, unfold the tripod 2 along the structural plate 1, and insert it into the ground through the stabilizing cone 22, place the plate 21 in contact with the ground, select the corresponding number of extension rods 9 according to the underground depth required for sampling, and assemble them through the first screw hole 10 and the screw rod 11, and install the bottom extension rod 9 and the connecting frame 3, and the slide 8 connects the extension rod 9 and the connecting frame 3. By setting the slide 8 in conjunction with the connecting frame 3, it is convenient to connect the bottom structure. The set extension rod 9 can be flexibly assembled according to the depth required for sampling, and at the same time, the pressure frame 12 connected thereto cooperates with the pressure plate 13 to press down to provide pressure, and improves the flexibility of the structure in actual use.

[0063] like Fig. 9 As shown, a sampling method of a rotary cutting sampling component for geological mineral resource exploration comprises the following steps:

[0064] S1. First, unfold the tripod 2 along the structural plate 1, and insert it into the ground through the stabilizing cone 22, place the plate 21 in contact with the ground, select the corresponding number of extension rods 9 according to the underground depth required for sampling, and assemble them through the first screw hole 10 and the screw 11, and install the bottom extension rod 9 and the connecting frame 3;

[0065] S2. A set of sample cylinders 706 are clamped on the outside of the clamping ring 705, and the hole on the top is aligned with the second screw hole 16, and then the assembly frame 704 is clamped on the top of the sample cylinder 706, and the bolt 17 is screwed into the second screw hole 16 to complete the assembly of the structure;

[0066] S3. The reduction motor 702 drives the rotary cutting structure 703 to rotate, and the driving motor 5 drives the crankshaft 6 to rotate. When the crankshaft 6 rotates, it will repeatedly push and pull the upper shell 701 and the bottom structure to reciprocate and vertically lift. The upper shell 701 is restricted by the limit frame 4 and will not swing, but will only reciprocate in a straight line. When a person applies a heavy object through the pressure frame 12 or a person directly steps on it, it will push the lower drilling device 7 to feed;

[0067] S4. The upper blade 703d and the lower blade 703e of the rotary cutting structure 703 cooperate with the blade shaft 703c to break up the soil layer and place it into the sample tube 706 when rotating. When the single sampling depth is consistent with the length of the sample tube 706, it can be taken out and the internal sample is retained. Then the sample tube 706 is replaced and installed, and the sampling is repeated;

[0068] S5. When the samples attached to the surfaces of the knife shaft 703c, the upper knife 703d and the lower knife 703e are difficult to remove, the knocking sheet 15 can be knocked, and the knife shaft 703c and the lower knife 703e move downward together. When the knife shaft 703c moves, the rectangular sheet 20 and the slide bar 703b fall at the same time, but the rectangular sheet 20 will push the fluid medium inside the inner cylinder 18 to flow and be buffered, so the displacement of the lower knife 703e will be greater, and the attached samples will be shaken off when the lower knife 703e and the knife shaft 703c are shaken respectively.

[0069] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

10. A sampling method for a rotary cutting sampling member for geological and mineral resource exploration according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, unfold the tripod (2) along the structural plate (1), and insert it into the ground through the stabilizing cone (22), place the plate (21) in contact with the ground, select the corresponding number of extension rods (9) according to the underground depth required for sampling, and assemble them through the first screw hole (10) and the screw rod (11), and install the bottom extension rod (9) and the connecting frame (3); S2. A set of sample tubes (706) are clamped on the outside of the clamping ring (705), and the hole on the top is aligned with the second screw hole (16), and then the assembly frame (704) is clamped on the top of the sample tube (706), and the bolt (17) is screwed into the second screw hole (16) to complete the assembly of the structure; S3. The reduction motor (702) drives the rotary cutting structure (703) to rotate, and at the same time, the driving motor (5) drives the crankshaft (6) to rotate. When the crankshaft (6) rotates, it repeatedly pushes and pulls the upper shell (701) and the bottom structure to reciprocate and vertically lift. The upper shell (701) is restricted by the limit frame (4) and therefore does not swing, but only reciprocates in linear motion. When a person applies a heavy object through the pressure frame (12) or a person directly steps on it to apply force, it pushes the lower drilling device (7) to feed; S4. The upper blade (703d) and the lower blade (703e) of the rotary cutting structure (703) cooperate with the blade shaft (703c), and when rotating, the soil layer is broken and placed into the interior of the sample tube (706). When the single sampling depth is consistent with the length of the sample tube (706), it can be taken out and the internal sample is retained, and then the sample tube (706) is replaced and installed, and the sampling is repeated; S5. When the sample attached to the surface of the knife shaft (703c), the upper knife (703d) and the lower knife (703e) is difficult to remove, the knocking sheet (15) can be knocked, and the knife shaft (703c) and the lower knife (703e) move downward together. When the knife shaft (703c) moves, the rectangular sheet (20) and the slide bar (703b) fall at the same time, but the rectangular sheet (20) will push the fluid medium inside the inner tube (18) to flow and be buffered, so the displacement of the lower knife (703e) will be greater, and the attached sample will be shaken off when the lower knife (703e) and the knife shaft (703c) are shaken separately.
