Description

Technical Field

[0001] This application relates to the technical field of geological exploration equipment, and in particular, to a geological exploration sampling device. Background Art

[0002] Geological exploration is an important link in modern resource development and environmental protection, and sampling technology is particularly crucial. Traditional geological exploration sampling methods mainly rely on manual excavation or simple tools for sampling. Although these methods are simple and easy to implement, there are many limitations in sampling in complex terrains and deep buried layers. With the progress of technology, automated sampling equipment has gradually become the mainstream. They not only improve the efficiency and accuracy of sampling, but also can adapt to a wider range of environmental conditions. Such equipment usually includes various drilling machines, samplers, etc., and is widely used in fields such as oil, minerals, and soil pollution monitoring.

[0003] In the existing geological exploration sampling technologies, common solutions mainly include manual samplers, electric samplers, and hydraulically driven sampling systems. Manual samplers rely on manual operation and are suitable for shallow sample collection, but they have a high labor intensity and low precision. Electric samplers drive the drill rod to rotate through a motor to achieve the collection of deeper samples, with high working efficiency and a certain degree of accuracy. The hydraulically driven sampling system uses high-pressure liquid to push the piston to move, enabling the drill to complete the sampling action, and is suitable for deeper depths and formations with greater hardness. In addition, there are also some composite sampling devices that combine multiple power sources and technical characteristics, such as pneumatic-electric hybrid drive systems, which further enhance the flexibility and application range of sampling.

[0004] However, the sampling devices in the existing technology generally have some deficiencies. Especially during the sample collection process, they are easily interfered by the outside world, resulting in sample mixing or loss. After the sample is taken out, additional operations are often required for preservation, increasing the complexity and time cost of on-site work. Therefore, how to design a geological exploration sampling device that can conveniently and quickly extract and preserve samples has become a technical problem to be solved urgently. Summary of the Invention

[0005] In order to overcome the above technical problems, this application provides a geological exploration sampling device.

[0006] A geological exploration sampling device provided by this application adopts the following technical solutions:

[0007] A geological exploration sampling device, including a support base, the support base is horizontally arranged, and a telescopic rod is fixedly connected to each of the four corners of the top surface of the support base. The telescopic rods are vertically arranged, and the tops of the four telescopic rods are fixedly connected with a support plate, and the support plate is also horizontally arranged; a motor is fixedly arranged at the center of the top surface of the support plate, and a communication hole is opened at the center of the top surface of the support plate. The size of the communication hole is adapted to the size of the output shaft of the motor, and the output shaft of the motor passes through the communication hole.

[0008] A drill rod is fixedly connected to the bottom end of the output shaft of the motor. The drill rod is coaxially arranged with the output shaft of the motor. A sampling hole is opened at the center of the top surface of the support base. The sampling hole is coaxially arranged with the drill rod. The diameter of the sampling hole is larger than the diameter of the drill rod. The drill rod passes through the sampling hole, and a spiral sampling groove is opened on the drill rod.

[0009] A sampling box is arranged between the support plate and the support base. The sampling box is sleeved on the drill rod. A matching hole is opened at the center of the top of the sampling box. The size of the matching hole is adapted to the size of the drill rod. A feed hole is opened at the bottom of the sampling box. The diameter of the feed hole is the same as the diameter of the sampling hole. The drill rod passes through the matching hole and the feed hole at the same time; the sampling box is made of a transparent material; the sampling box includes a first box body and a second box body, and the first box body and the second box body are detachably connected by a connecting component.

[0010] By adopting the above technical solution, the geological exploration sampling device can achieve stable and reliable drilling and sampling functions. The design of the support base and the telescopic rod ensures the stability of the entire device. The motor drives the drill rod for efficient drilling, and the spiral sampling groove helps the sample to smoothly enter the sampling box. The sampling box made of transparent material facilitates real-time observation of the sampling process, and the split box body design makes sample collection more convenient, avoiding the inconvenience caused by the traditional single structure. Specifically, the design of the support base and the telescopic rod keeps the entire device stable during operation, preventing the risk of tipping caused by vibration or external forces; the motor drives the drill rod to rotate, and the spiral sampling groove on the drill rod can effectively collect rock and soil samples, improving the efficiency and quality of sampling; the sampling box is made of transparent material, and the state of the sample can be observed in real time during sampling to ensure the smooth progress of the sampling process. When it is observed that the sample collection is full or the type of the sample being collected changes, the sampling can be stopped at any time, the sampling box corresponding to the sample can be disassembled, and an empty sampling box can be replaced to continue sampling; the design that the size of the mating hole is different from the size of the feed hole enables the size of the lower sampling hole to be larger than the size of the drill rod, facilitating the sample to enter the sampling box, and the size of the upper mating hole is adapted to the size of the drill rod, which can prevent the sample from flying out from the mating hole during sampling; the sampling box is divided into a first box body and a second box body, and is detachably connected through a connecting component, which is convenient for installing and disassembling the sampling box according to different needs, and is also convenient for cleaning and maintenance after sampling.

[0011] Optionally, the connecting component includes a connecting block. On both sides of the side wall of the first box body close to the second box body, a connecting groove is respectively opened. On both sides of the side wall of the second box body close to the first box body, a connecting block is respectively fixedly connected. The size of the connecting groove is adapted to the size of the connecting block, and the connecting block can penetrate into the connecting groove.

[0012] By adopting the above technical solution, the design of the connecting component makes the connection between the first box body and the second box body more stable and reliable, ensuring that no loosening phenomenon occurs during the sampling process. At the same time, this design is convenient for disassembly and assembly, and is convenient for users to quickly separate the first box body and the second box body after sampling, so as to achieve efficient cleaning and reuse.

[0013] Optionally, a sliding groove is respectively opened on the top surface and the bottom surface of the connecting block. The depth direction of the sliding groove is the vertical direction. A clamping block is slidably arranged in the sliding groove along the vertical direction. A first spring is fixedly connected between the clamping block and the bottom of the sliding groove. A clamping groove is respectively opened on the top wall and the bottom wall of the connecting groove. When the connecting block is located in the connecting groove and the clamping block is aligned with the clamping groove, the clamping block can be clamped in the clamping groove under the tension of the first spring.

[0014] By adopting the above technical solution, the design and cooperation of the clamping block and the first spring form a clamping structure between the connecting block and the connecting groove, enabling the first box body and the second box body of the sampling box to be firmly connected together, thereby improving the overall stability and reliability of the device. Specifically, when the connecting block is located in the connecting groove and the clamping block is aligned with the clamping groove, the clamping block can automatically snap into the clamping groove under the action of the first spring, ensuring the firmness of the connection.

[0015] Optionally, a slider is slidably arranged vertically in the clamping groove. When the clamping block is clamped in the clamping groove, the clamping block can be driven to disengage from the clamping groove and enter the sliding groove by pressing the slider.

[0016] By adopting the above technical solution, the design of the slider enables the clamping block to be conveniently disengaged from the clamping groove when needed, thereby realizing the quick separation and combination between the first box body and the second box body of the sampling box, improving the operation convenience and working efficiency of the sampling process. Specifically, when it is necessary to open or close the sampling box, simply pressing the slider can cause the clamping block to withdraw from the clamping groove, and then the connecting block can be taken out of the connecting groove, facilitating the separation of the first box body and the second box body. The operation is simple and fast, avoiding the cumbersome steps of traditional connection methods and enhancing the user experience.

[0017] Optionally, the longitudinal section of the connecting groove is T-shaped, and the longitudinal section of the connecting block is also T-shaped. The size of the connecting block is adapted to the size of the connecting groove; the cross-section of the clamping groove is T-shaped, and the longitudinal section of the slider is also T-shaped. The size of the slider is adapted to the size of the clamping groove.

[0018] By adopting the above technical solution, the T-shaped structure design of the connecting groove and the connecting block makes the connection more stable, effectively preventing the connecting block from falling off during use and improving the overall stability of the device. At the same time, the T-shaped structure design of the clamping groove and the slider ensures that the clamping block can be stably clamped in the clamping groove, enhancing the reliability and durability of the connecting component.

[0019] Optionally, switch assemblies are provided at both the top and bottom of the sampling box, and the switch assemblies are used to assist in controlling the opening and closing of the mating hole and the feed hole.

[0020] By adopting the above technical solution, switch assemblies are provided at both the top and bottom of the sampling box, and the switch assemblies can effectively control the opening and closing of the mating hole and the feed hole. Specifically, this design can ensure that during the rotation of the drill pipe, both the mating hole and the feed hole are in the open state; when transported after disassembly, both the mating hole and the feed hole are in the closed state, reducing the dropping of samples.

[0021] Optionally, the switch assembly includes a cover plate. A mating groove is respectively provided at the top and bottom of the side wall of the first box body close to the second box body. A moving groove is respectively provided at the top and bottom of the side wall of the second box body close to the first box body. The depth directions of the moving groove and the mating groove are both horizontal and in the same direction. The sizes of the moving groove and the mating groove are both adapted to the size of the cover plate. The cover plate is slidably arranged in the moving groove along the depth direction of the moving groove, and one side of the cover plate close to the mating groove can also penetrate into the mating groove.

[0022] By adopting the above technical solution, the switch assembly is reasonably designed and has a compact structure. The combined use of the cover plate with the moving groove and the mating groove ensures the sealing performance of the top and bottom of the sampling box, effectively preventing the leakage of soil samples during the movement. At the same time, the sliding arrangement of the cover plate makes the opening and closing operations simple and fast, improving the efficiency and convenience of sampling.

[0023] Optionally, an operation groove is provided on the top surface of the second box body. The operation groove communicates with the moving groove in the vertical direction. The length direction of the operation groove is horizontal and parallel to the moving direction of the cover plate. An operation block is slidably arranged in the operation groove along its length direction. The bottom surface of the operation block is fixedly connected to the top surface of the cover plate.

[0024] By adopting the above technical solution, the geological exploration sampling device can achieve the following effects: The setting of the operation groove enables the user to conveniently control the opening and closing of the cover plate through the operation block, thus more easily completing the opening and closing operations of the sampling box, improving the operation convenience and working efficiency of the device; The fixed connection design between the operation block and the cover plate ensures the stability of the cover plate during movement, avoiding the problem of sample leakage caused by loosening, and further enhancing the sealing performance of the sampling device; The design of the operation groove not only facilitates the operation but also enhances the overall structural strength of the second box body, making the entire sampling device more durable and suitable for the use requirements in various complex geological environments.

[0025] Optionally, a first positioning hole is formed in the side wall on one side of the moving slot. The depth direction of the first positioning hole is horizontal and perpendicular to the length direction of the operation slot. A first positioning rod is slidably arranged in the first positioning hole along its depth direction. A first limiting slot is formed in the side wall on one side of the first positioning hole. The length direction of the first limiting slot is parallel to the depth direction of the first positioning hole. A first limiting block is slidably arranged in the first limiting slot along its length direction. The first limiting block is fixedly connected to the first positioning rod. A first limiting spring is further arranged in the first limiting slot. The first limiting spring is located on the side of the first limiting block away from the moving slot. The axis direction of the first limiting spring is parallel to the sliding direction of the first limiting block. One end of the first limiting spring is fixedly connected to the first limiting block, and the other end is fixedly connected to the side wall of the first limiting slot. A positioning slot is formed in the side of the cover plate close to the first positioning hole. The size of the positioning slot is adapted to the size of the first positioning rod. When the first positioning rod is aligned with the positioning slot, the first positioning rod can be clamped in the positioning slot under the tension of the first limiting spring, and at this time the cover plate is in an open state.

[0026] By adopting the above technical solution, the cover plate of the geological exploration sampling device can be conveniently locked in the open state. Specifically, the design of the first positioning hole and the first positioning rod enables the first positioning rod to be inserted into the positioning slot on the cover plate through a simple operation when the cover plate needs to be opened. Under the action of the first limiting spring, it is ensured that the first positioning rod firmly clamps the positioning slot, thereby maintaining the open state of the cover plate. This design not only simplifies the operation process but also improves the reliability and stability of the device during use, avoiding the influence on the smooth progress of the sampling work due to the accidental closing of the cover plate caused by external factors.

[0027] Optionally, a second positioning hole is formed in the side wall on one side of the fitting groove, and the depth direction of the second positioning hole is parallel to the depth direction of the first positioning hole; a second positioning rod is slidably arranged in the second positioning hole along its depth direction, a second limiting groove is formed in the side wall on one side of the second positioning hole, the length direction of the second limiting groove is parallel to the depth direction of the second positioning hole, a second limiting block is slidably arranged in the second limiting groove along its length direction, the second limiting block is fixedly connected with the second positioning rod, a second limiting spring is further arranged in the second limiting groove, the second limiting spring is located on the side of the second limiting block away from the moving groove, the axis direction of the second limiting spring is parallel to the sliding direction of the second limiting block, one end of the second limiting spring is fixedly connected with the second limiting block, and the other end is fixedly connected with the side wall of the second limiting groove; when the second positioning rod is aligned with the positioning groove, the second positioning rod can be clamped in the positioning groove under the tension of the second limiting spring, at this time the cover plate is in a closed state, and the first positioning rod abuts against the side wall of the cover plate close to the first positioning rod.

[0028] By adopting the above technical solution, the cover plate of the sampling box can be firmly held in a closed state, preventing sample leakage or contamination during the moving process. Specifically, the design of the second positioning rod and the second limiting spring ensures that the cover plate can be reliably locked in the closed state, avoiding accidental opening of the cover plate due to external vibration or other factors. In addition, when the second positioning rod is clamped in the positioning groove, the abutment of the first positioning rod against the side wall of the cover plate is also realized, further enhancing the stability of the cover plate and also strengthening the stability between the first box body and the second box body.

[0047] This geological exploration sampling device can achieve a stable and reliable drilling and sampling function. The design of the support base 1 and the telescopic rod 11 ensures the stability of the whole device. The motor 22 drives the drill pipe 3 for efficient drilling, and the spiral sampling groove 31 helps the sample to smoothly enter the sampling box 4. The transparent sampling box 4 made of transparent material facilitates real-time observation of the sampling process, and the split box body design makes sample collection more convenient, avoiding the inconvenience brought by the traditional single structure.

When the connecting block 71 is located in the connecting groove 51 and the clamping block 72 is aligned with the clamping groove 52, the clamping block 72 can be clamped in the clamping groove 52 under the tension of the first spring 73.

[0052] When assembling the sampling box 4, before inserting the connecting block 71 into the connecting groove 51, first press the clamping block 72 into the sliding groove 711 to compress the first spring 73.

At the same time, the T-shaped structure design of the clamping groove 52 and the sliding block 74 ensures that the clamping block 72 can be stably clamped in the clamping groove 52, enhancing the reliability and durability of the connecting component 7.

[0056] Refer to Figure 6 , switch assemblies 8 are provided at both the top and bottom of the sampling box 4. The switch assemblies 8 are used to assist in controlling the opening and closing of the mating holes 41 and the feed holes 42. This design can ensure that during the rotation of the drill pipe 3, both the mating holes 41 and the feed holes 42 are in the open state to cooperate with the drilling of the drill pipe 3; when transported after disassembly, both the mating holes 41 and the feed holes 42 are in the closed state, making the sampling box 4 in a sealed state to avoid the dropping of samples.

[0057] Refer to Figure 6 , the switch assembly 8 includes a cover plate 81. A mating groove 53 is respectively opened at the top and bottom of the side wall of the first box body 5 close to the second box body 6. A moving groove 61 is respectively opened at the top and bottom of the side wall of the second box body 6 close to the first box body 5. The depth directions of the moving groove 61 and the mating groove 53 are both horizontal and in the same direction. The sizes of the moving groove 61 and the mating groove 53 are both adapted to the size of the cover plate 81. The cover plate 81 is slidably arranged in the moving groove 61 along the depth direction of the moving groove 61, and one side of the cover plate 81 close to the mating groove 53 can also penetrate into the mating groove 53.

An operation block 82 is slidably arranged in the operation slot 64 along its length direction. The bottom surface of the operation block 82 is fixedly connected to the top surface of the cover plate 81. The setting of the operation slot 64 enables the user to conveniently control the opening and closing of the cover plate 81 through the operation block 82, thereby more easily completing the opening and closing operations of the sampling box 4, improving the operation convenience and working efficiency of the device; the fixed connection design between the operation block 82 and the cover plate 81 ensures the stability of the cover plate 81 during movement, avoiding the problem of sample leakage caused by loosening, and further enhancing the sealing performance of the sampling device; the design of the operation slot 64 not only facilitates operation but also enhances the overall structural strength of the second box body 6, making the entire sampling device more durable and suitable for use requirements in various complex geological environments.

[0060] Referring to Figure 6 and Figure 7 , a first positioning hole 62 is provided on the side wall of one side of the moving slot 61. The depth direction of the first positioning hole 62 is horizontal and perpendicular to the moving direction of the cover plate 81; a first positioning rod 83 is slidably arranged in the first positioning hole 62 along its depth direction.

[0061] Referring to Figure 7 and Figure 8 , a first limiting slot 63 is provided on the side wall of one side of the first positioning hole 62. The length direction of the first limiting slot 63 is parallel to the depth direction of the first positioning hole 62. A first limiting block 84 is slidably arranged in the first limiting slot 63 along its length direction. The first limiting block 84 is fixedly connected to the first positioning rod 83. A first limiting spring 85 is also provided in the first limiting slot 63. The first limiting spring 85 is located on the side of the first limiting block 84 away from the moving slot 61. The axial direction of the first limiting spring 85 is parallel to the sliding direction of the first limiting block 84. One end of the first limiting spring 85 is fixedly connected to the first limiting block 84, and the other end is fixedly connected to the side wall of the first limiting slot 63; a positioning slot 811 is provided on the side of the cover plate 81 close to the first positioning hole 62. The size of the positioning slot 811 is adapted to the size of the first positioning rod 83. When the first positioning rod 83 is aligned with the positioning slot 811, the first positioning rod 83 can be clamped in the positioning slot 811 under the tension of the first limiting spring 85, and at this time the cover plate 81 is in the open state.

[0062] The cover plate 81 of the geological exploration sampling device can be conveniently locked in the open state. Specifically, the design of the first positioning hole 62 and the first positioning rod 83 enables the first positioning rod 83 to be snapped into the positioning groove 811 on the cover plate 81 when the cover plate 81 needs to be opened. Under the action of the first limiting spring 85, it is ensured that the first positioning rod 83 firmly catches the positioning groove 811, thereby maintaining the open state of the cover plate 81.

[0063] Before connecting and sleeving the sampling box 4 on the drill pipe 3, first pull the first positioning rod 83 in a direction away from the moving groove 61 to withdraw the first positioning rod 83 from the moving groove 61. At this time, the first limiting spring 85 is in a compressed state. Then move the operating block 82 to drive the cover plate 81 to move to a position where the positioning groove 811 is aligned with the first positioning rod 83. At this time, release the first positioning rod 83, and the first limiting spring 85 drives the first limiting block 84 to move in a direction close to the cover plate 81, driving the first positioning rod 83 to penetrate into the positioning groove 811 to keep the cover plate 81 in the open state; the above steps are adopted at both the top and bottom of the second box body 6 to keep the cover plates 81 at the top and bottom in the open state, avoiding interference with the operation of the drill pipe 3 caused by the closure of the cover plate 81.

[0064] Refer to Figure 8 and Figure 9 As shown in [relevant figures], a second positioning hole 54 is formed in the side wall of one side of the mating groove 53. The depth direction of the second positioning hole 54 is parallel to the depth direction of the first positioning hole 62; a second positioning rod 86 is slidably arranged in the second positioning hole 54 along its depth direction. A second limiting groove 55 is formed in the side wall of one side of the second positioning hole 54. The length direction of the second limiting groove 55 is parallel to the depth direction of the second positioning hole 54. A second limiting block 87 is slidably arranged in the second limiting groove 55 along its length direction. The second limiting block 87 is fixedly connected to the second positioning rod 86. A second limiting spring 88 is also arranged in the second limiting groove 55. The second limiting spring 88 is located on the side of the second limiting block 87 away from the moving groove 61. The axial direction of the second limiting spring 88 is parallel to the sliding direction of the second limiting block 87. One end of the second limiting spring 88 is fixedly connected to the second limiting block 87, and the other end is fixedly connected to the side wall of the second limiting groove 55; when the second positioning rod 86 is aligned with the positioning groove 811, the second positioning rod 86 can be snapped into the positioning groove 811 under the tension of the second limiting spring 88. At this time, the cover plate 81 is in a closed state, and the first positioning rod 83 abuts against the side wall of the cover plate 81 close to the first positioning rod 83.

[0065] The cover plate 81 of the sampling box 4 can be firmly held in the closed state to prevent sample leakage or contamination during movement. The design of the second positioning rod 86 and the second limiting spring 88 ensures that the cover plate 81 can be reliably locked in the closed state, avoiding accidental opening of the cover plate 81 due to external vibration or other factors. In addition, while the second positioning rod 86 is snapped into the positioning groove 811, the first positioning rod 83 abuts against the side wall of the cover plate 81, further enhancing the stability of the cover plate 81 and also strengthening the stability between the first box body 5 and the second box body 6.

[0066] When disassembly is required after sampling, move the slider 74 in the direction close to the clamping block 72 so that the slider 74 abuts against the clamping block 72 located in the clamping groove 52, and push the clamping block 72 into the sliding groove 711 through the slider 74 to withdraw it from the clamping groove 52. At this time, take out the connecting block 71 from the connecting groove 51 to separate the first box body 5 and the second box body 6. While separating, observe the distance between the first box body 5 and the second box body 6. When the distance between the first box body 5 and the second box body 6 is greater than the diameter of the drill rod 3, stop taking out the connecting block 71, and move the first box body 5 and the second box body 6 horizontally in any direction until the drill rod 3 exits from between the first box body 5 and the second box body 6. At this time, reinsert the connecting block 71 into the connecting groove 51 so that the clamping block 72 is snapped into the clamping groove 52 to assemble the first box body 5 and the second box body 6; then pull the first positioning rod 83 at the top away from the cover plate 81 to drive the first positioning rod 83 to withdraw from the positioning groove 811, move the operating block 82 to drive the cover plate 81 to move in the direction close to the mating groove 53, and at the same time pull the second positioning rod 86 away from the mating groove 53 to make the second positioning rod 86 withdraw from the mating groove 53, and the second limiting spring 88 is in a compressed state until the positioning groove 811 is aligned with the second positioning rod 86. At the same time, release the second positioning rod 86 and the first positioning rod 83 so that the second positioning rod 86 is snapped into the positioning groove 811 under the tension of the second limiting spring 88, and the first positioning rod 83 moves in the direction close to the moving groove 61 under the action of the first limiting spring 85 and abuts against the cover plate 81 to complete the closing of the top cover plate 81; then turn over the sampling box 4 and repeat the above steps to close the cover plate 81 on the other side of the sampling box 4.

[0067] The implementation principle of the geological exploration sampling device in the embodiment of the present application is as follows:

[0068] Before working, first connect a set of split first box bodies 5 and second box bodies 6 and sleeved them on the drill pipe 3. The steps are as follows: Press the clamping blocks 72 at the top and bottom of the second box body 6 into the corresponding sliding grooves 711, so that the first spring 73 is in a compressed state. Then align the connecting block 71 and insert it into the connecting groove 51 until the clamping block 72 is aligned with the clamping groove 52. The clamping block 72 can be clamped in the clamping groove 52 under the tension of the first spring 73, so as to realize the connection of the first box body 5 and the second box body 6 through the assembly of the connecting block 71;

[0069] During working, place the support base 1 at the required position, align the drill pipe 3 with the position where drilling and sampling are required, hold the hand-held rod 21 by hand to maintain stability, start the motor 22, the motor 22 drives the drill pipe 3 to rotate. While the drill pipe 3 is rotating, press down the hand-held rod 21 with both hands to drive the motor 22 and the drill pipe 3 to move downward, and gradually drill into the position where sampling is required. After the drill pipe 3 drills into the formation, the sample moves upward through the sampling groove 31 on the drill pipe 3, and enters the sampling box 4 through the sampling hole 12 and the feed hole 42; Observe the sample in the sampling box 4. When the material of the sample changes or the sampling box 4 is full of the sample, stop the drill pipe 3 from working, replace the empty sampling box 4 and continue sampling;

[0070] When disassembling the sampling box 4 containing the sample, move the slider 74 towards the direction close to the clamping block 72, so that the slider 74 abuts against the clamping block 72 located in the clamping groove 52. Push the clamping block 72 into the sliding groove 711 through the slider 74 and withdraw it from the clamping groove 52. At this time, take out the connecting block 71 from the connecting groove 51 to separate the first box body 5 and the second box body 6. While separating, observe the distance between the first box body 5 and the second box body 6. When the distance between the first box body 5 and the second box body 6 is greater than the diameter of the drill pipe 3, stop taking out the connecting block 71. Move the first box body 5 and the second box body 6 horizontally towards any side until the drill pipe 3 withdraws from between the first box body 5 and the second box body 6. At this time, reinsert the connecting block 71 into the connecting groove 51, make the clamping block 72 snap into the clamping groove 52, and assemble the first box body 5 and the second box body 6; then pull the first positioning rod 83 at the top away from the cover plate 81, drive the first positioning rod 83 to withdraw from the positioning groove 811, move the operation block 82 to drive the cover plate 81 to move towards the direction close to the mating groove 53, and at the same time pull the second positioning rod 86 away from the mating groove 53 to make the second positioning rod 86 withdraw from the mating groove 53. The second limiting spring 88 is in a compressed state until the positioning groove 811 is aligned with the second positioning rod 86. At the same time, release the second positioning rod 86 and the first positioning rod 83, so that the second positioning rod 86 is snapped into the positioning groove 811 under the tension of the second limiting spring 88, and the first positioning rod 83 moves towards the direction close to the moving groove 61 under the action of the first limiting spring 85 and abuts against the cover plate 81 to complete the closing of the top cover plate 81; then flip the sampling box 4 and repeat the above steps to close the cover plate 81 on the other side of the sampling box 4.

[0071] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
