Description

Technical Field

[0001] The present invention relates to the technical field of soil detection and sampling, and particularly to an undisturbed soil ripening detection and sampling device and a detection method for sloping farmland. Background Art

[0002] At present, the ripening of undisturbed soil in sloping farmland is a process aimed at improving soil fertility and soil structure. Especially in the sloping land environment where soil erosion is easy to occur, it is particularly important to ripen the soil. The detection of undisturbed soil ripening in sloping farmland is a process of evaluating the quality, fertility and structural improvement of the soil in sloping farmland after ripening treatment. The Chinese patent with the application number CN202410437618.8 discloses "a layered sampling device for detecting undisturbed soil in sloping farmland; including a frame, on which a drilling and advancing mechanism for moving into the soil layer is assembled; the drilling and advancing mechanism includes a stroke frame vertically slidably installed on the frame, and a plurality of drill barrel assemblies are vertically rotatably installed on the stroke frame. The stroke frame is equipped with a rotation driving component for driving a plurality of drill barrel assemblies to rotate synchronously; the device provided by the present invention can obtain multiple samples during a single sampling process, which can not only compare samples to reduce the influence of random sampling, but also provide multiple sample backups; in addition, the double-layer sleeve combination of the built-in drill barrel and the external drill barrel and the separate quick-release design are adopted in the drill barrel assembly. The built-in drill barrel adopts a split structure design, and multiple groups of windows are arranged inside and outside, which can adjust the sampling pressure, realize rapid layered sampling and rapid complete sampling, and ensure the sampling quality and integrity of the samples."

[0003] This existing technology only solves the following drawbacks that obviously exist in the existing soil sampling equipment: 1) The sampler with a single drill barrel structure can only complete single-sample sampling at a time. When the quality of the sampled sample is not good or it cannot be used as a test sample due to damage, it is necessary to repeat sampling many times, which is rather inconvenient;

[0004] When sampling deeper soil layers, as the drilling progresses, the pressure inside the drill barrel will gradually increase. On the one hand, it may damage the structure of the drill barrel itself. On the other hand, the sampled sample will be squeezed and damaged. Especially when it is necessary to obtain information on the distribution state of the soil layer, it will affect the integrity and accuracy of the sampled sample. Most of the existing general samplers do not have a pressure relief structure, and the pressure relief state of the sampler with a pressure relief structure is generally not adjustable, and it cannot perform adaptive pressure relief according to the state of the soil to be detected;

[0005] The drill barrels of some samplers are mostly complete cylindrical structures, or there are notches on the drill barrels, but basically the sampled sample is taken out of the barrel by pushing from one end of the drill barrel. Careful operation is required when withdrawing. If the operation is improper, it is easy to damage the integrity of the sample and cause sampling failure. Especially when the sample fits tightly in the drill barrel, the difficulty of withdrawal will increase;

[0006] However, during the use process, it is impossible to detect the density of the sampled soil while sampling. Moreover, even when detecting the density of the treated soil, it is impossible to adjust the power of the power end according to the soil density, and it is also impossible to detect the humidity at multiple positions of the sample. If the sample is carried to the laboratory for testing after sampling, it will cause the humidity of the sample to change, resulting in errors in the final test results. In addition, when the density of the soil decreases, the state of the sample will be relatively loose, resulting in the situation where sampling cannot be successfully completed in the end.

[0018] A detection method for a detection sampling device for the ripening of undisturbed soil on sloping farmland includes the following steps:

[0019] Step 1: When sampling, move the working frame to the position where sampling is required, and then start the single-phase motor to drive the rotating gear to rotate through the rotating rod. When single-point or multi-point simultaneous sampling is required, the corresponding fixed electromagnet will be triggered, causing the corresponding fixed electromagnet to lose magnetism, so that the connecting magnetic plate and the transmission gear at the corresponding position lose restraint. The movable mounting rod is driven to move downward by the stretched movable spring, and the transmission gear is driven to move downward, so that the transmission gear meshes with the rotating gear, driving the transmission gear to rotate, driving the rotating screw to rotate in the inner cavity of the moving sliding cylinder, and driving the moving slider to move inside the moving sliding cylinder. When the moving slider moves inside the moving sliding cylinder and contacts the corresponding positioning touch switch, an alarm will be triggered through the alarm outside the control panel to tell the staff the depth during material taking.

[0020] Step 2: Drive the fixed block to move downward by moving the slider, which drives the sampling cylinder to move downward. When the sampling cylinder moves downward, it passes through the material taking through hole and contacts the soil. When the sampling cylinder continues to move downward, it will contact and squeeze the soil, moving the soil into the sampling cylinder. When the sampling cylinder moves downward, it will squeeze the material taking guide bar into the soil, so as to squeeze and limit the soil, and the limiting inclined groove squeezes and fixes the sampled soil. During the sampling process, the air at the upper end of the sampling cylinder is transported into the movable through hole. When the air flow flows in the inner cavity of the movable through hole, the air flow contacts the pushing sleeve, pushing the pushing sleeve to move upward, which drives the installation ring bar to move upward and drives the installation slide rod to slide in the installation chute, increasing the stability when the installation ring bar and the pushing sleeve move. When the installation slide rod moves, it squeezes the compression spring. Later, the compressed compression spring drives the installation slide rod, the installation ring bar and the pushing sleeve to reset. When the installation slide rod moves, it drives the communication guide block to move. When the communication guide block slides upward outside the coil, the resistance of the single-phase motor is reduced, improving the efficiency of the single-phase motor, and triggering the alarm light arranged outside the control panel to give an alarm. When the density of the sampled soil is greater, the air pressure formed at the upper end of the sampling cylinder during sampling will be greater, so the driving force generated on the pushing sleeve will be greater, and the resistance of the single-phase motor during operation will be smaller. When the water content of the soil during sampling is too high, the liquid will flow into the limiting inclined groove and accumulate at the bottom end of the limiting inclined groove, making the two connecting guide blocks connected, and triggering the alarm outside the control panel to give an alarm. After the material taking is completed, start the electric push rod to drive the fixed cross bar to move downward, drive the extrusion ejector rod to move downward, and drive one side of the limiting block to move downward with the hinge as the axis. When moving, drive the docking slider to slide in the moving chute, so that the limiting block contacts and squeezes the bottom end of the sampling body, which can not only cut off the bottom end of the sampled body, but also limit and fix the sampled body, increasing the integrity of the sampled body during sampling. When the limiting block contacts and squeezes the bottom end of the sampled body, when there is too much liquid in the sampled body, the liquid in the sampled body is squeezed into the receiving notch through the extrusion filter plate, and the liquid gathers at the bottom end of the inner cavity of the receiving notch, and triggers the liquid level touch switch to start the alarm arranged outside the control panel to give an alarm;

[0021] Step three: when sampling is completed and detection is performed, the electric push rod is started to drive the fixed cross bar to move downward, and the reset spring rod is squeezed. Later, the fixed cross bar is driven to move upward and reset through the reset spring rod after squeezing, and the extrusion push rod and the movable push rod are driven to move upward and reset, and the movable push rod is driven downward through the fixed cross bar, and the extrusion top ball is driven downward, so that the extrusion top ball contacts the inclined surface of the moving inclined block, and pushes the moving inclined block to move to one side of the installation slot, and squeezes the installation spring. Later, the moving inclined block and the extrusion rod are reset by the installation spring after squeezing. When the moving inclined block moves, the extrusion rod is driven to slide inside the active hole, and the detection head is driven to move inside the active hole, so that the detection head and the sealing rubber ring are stretched open, so that the extrusion rod and the detection head are inserted into the sample body, and the detection instrument is started to detect the sample body. When the extrusion rod and the detection head are inserted into the sample body, the volume of the sample body expands, thereby increasing the fit between the sample body and the inner cavity of the sampling tube.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the process of sampling and testing, the present invention can not only sample multiple points at the same time, but also sample separately at different points, thereby increasing the applicability of the sampling process. In addition, the present invention can also perform testing while sampling. When sampling, the density of the soil is first tested. If it is detected that the soil density is high, not only can an alarm be issued to inform the staff, but the power of the sampling power end can also be adjusted to ensure the stability during sampling. When sampling, the sample can also be limited and fixed to ensure the integrity of the sample and avoid the sample from slipping during sampling. At the same time, the sample humidity at multiple positions of the sample can be tested, and the test results can be fed back to the control panel to inform the staff of the specific situation of the sample. By obtaining the sample data at the first time during sampling, the accuracy of the later sample detection is improved, thereby avoiding the situation that the real data of the sample cannot be collected at the first time during the sampling process. If the sample is moved to the test area again, the final result will be erroneous.

[0024] 2. The present invention also detects various positions of the sample through the detection instrument during the sampling process, thereby increasing the comprehensiveness of the sample detection process and improving the efficiency and accuracy of the sample detection. When the sample is detected, the sample can also be limited and fixed to increase the integrity of the sample during the sampling process, avoiding the situation in which only a part of the sample can be initially detected during the sampling and detection process, which easily leads to insufficient detection, resulting in only local detection during detection, and the data obtained is not comprehensive enough, and when the sample is moved up, the combined effect of pressure and gravity causes the sample to slide down, resulting in unsuccessful structure.

The connecting guide blocks 405 and the induction start switches 419 are electrically connected with the control panel. The top ends of the sampling cylinders 401 are all of a hollow structure;

[0043] On one side of the inner cavity of the fixed block 501 and the sampling cylinder 401 close to the moving sliding cylinder 307, movable sliding holes are provided, and extrusion ejector rods 406 are movably installed in the inner cavities of the movable sliding holes. The limit stoppers 504 are all triangular in structure. Hinges are installed between the upper ends of one side of the limit stoppers 504 and the bottom end of the sampling cylinder 401, and a sealing sleeve is installed outside the hinges. On the side of the limit stoppers 504 away from the moving sliding cylinder 307, receiving notches 414 are provided. One side of the inner cavity of the receiving notch 414 is of an inclined surface structure. Liquid level touch switches 416 are installed at the bottom ends of one side of the inner cavity of the receiving notch 414. The liquid level touch switches 416 are electrically connected to the control panel. On one side of the top ends of the limit stoppers 504, moving sliding grooves 417 are provided. Docking sliders 418 are slidably installed on the side of the moving sliding grooves 417 away from the moving sliding cylinder 307. The bottom ends of the extrusion ejector rods 406 pass through the movable sliding holes and are connected to the top ends of the docking sliders 418 through hinges;

[0044] The specific implementation method is as follows: By moving the slider 306 to drive the fixed block 501 to move downward, the sampling cylinder 401 is driven to move downward. When the sampling cylinder 401 moves downward, it passes through the material taking through hole 9 and contacts the soil. When the sampling cylinder 401 continues to move downward, it will contact and squeeze the soil, moving the soil into the sampling cylinder 401. When the sampling cylinder 401 moves downward, the material taking guide bar 402 will be squeezed into the soil, so as to squeeze the soil and the limiting inclined groove 403 squeezes and fixes the sampled soil. During the sampling process, the air at the upper end of the sampling cylinder 401 is transported into the movable through hole 407. When the air flow flows in the inner cavity of the movable through hole 407, the air flow contacts the pushing sleeve 408, pushing the pushing sleeve 408 to move upward, driving the mounting ring bar 409 to move upward, and driving the mounting slide bar 411 to slide in the mounting chute 410, increasing the stability when the mounting ring bar 409 and the pushing sleeve 408 move. When the mounting slide bar 411 moves, it squeezes the compression spring 413. Later, the compressed compression spring 413 drives the mounting slide bar 411, the mounting ring bar 409 and the pushing sleeve 408 to reset. When the mounting slide bar 411 moves, it drives the connecting guide block to move. When the connecting guide block slides upward outside the coil 412, the resistance of the single-phase motor 301 is reduced, improving the efficiency of the single-phase motor 301, and triggering the alarm light arranged outside the control panel to give an alarm. When the density of the sampled soil is greater, the air pressure formed at the upper end of the sampling cylinder 401 during sampling will be greater, so the driving force generated on the pushing sleeve 408 will be greater, and the resistance of the single-phase motor 301 during operation will be smaller. When the water content of the soil during sampling is too high, the liquid will flow into the limiting inclined groove 403 and gather at the bottom end inside the limiting inclined groove 403, causing the two connecting guide blocks 405 to be connected, and triggering the alarm outside the control panel to give an alarm. After the material taking is completed, the electric push rod 503 is started to drive the fixed cross bar 515 to move downward, driving the extrusion top rod 406 to move downward, and driving the side of the limiting block 504 to move downward with the hinge as the axis. When moving, it drives the docking slider 418 to slide in the moving chute 417, so that the limiting block 504 contacts and squeezes the bottom end of the sampling body, which can not only cut off the bottom end of the sampled body, but also limit and fix the sampled body, increasing the integrity of the sampled body during sampling. When the limiting block 504 contacts and squeezes the bottom end of the sampled body, when there is too much liquid in the sampled body, the liquid in the sampled body is squeezed into the receiving notch 414 through the extrusion filter plate 415, and the liquid gathers at the bottom end inside the receiving notch 414, triggering the liquid level touch switch 416 to start the alarm arranged outside the control panel to give an alarm. When the humidity of the sampled body during sampling is too high, the generated moisture is absorbed by the moisture absorption layer 404, and the weight of the moisture absorption layer 404 will increase, driving the movable rod 423 and the movable top block 421 to move downward, so that one side of the movable top block 421 contacts the induction start switch 419, triggering the control panel to give an alarm through the alarm arranged inside the control panel.

At the position of the material taking guide bar 402 in the inner cavity of the installation through groove 509, an activity port is opened. And on the side of the inner cavity of the activity port away from the installation through groove 509, a sealing rubber ring 514 is installed. A round hole is respectively opened in the middle of each sealing rubber ring 514.

[0047] The specific implementation method is as follows: when the sampling is completed and the test is performed, the electric push rod 503 is started to drive the fixed cross bar 515 to move downward, and the reset spring rod 516 is squeezed. Later, the reset spring rod 516 after squeezing drives the fixed cross bar 515 to move upward and reset, and drives the extrusion ejector rod 406 and the movable ejector rod 507 to move upward and reset, and drives the movable ejector rod 507 to move downward through the fixed cross bar 515, and drives the extrusion ejector ball 506 to move downward, so that the extrusion ejector ball 506 contacts the inclined surface of the movable inclined block 508, and pushes the movable inclined block 508 to move to the side of the installation slot 509, and the installation spring 511 is pressed. After extrusion, the installed spring 511 after extrusion drives the movable inclined block 508 and the extrusion rod 512 to reset. When the movable inclined block 508 moves, it drives the extrusion rod 512 to slide inside the movable hole, and then drives the detection head 513 to move inside the movable hole, so that the detection head 513 and the sealing rubber ring 514 are stretched open, so that the extrusion rod 512 and the detection head 513 are inserted into the sample body, and the detection instrument 8 is started to detect the sample body. When the extrusion rod 512 and the detection head 513 are inserted into the sample body, the volume of the sample body is expanded, thereby increasing the fit between the sample body and the inner cavity of the sampling tube 401.

[0048] Embodiment 2

[0049] A detection method for a sloping cultivated land original soil maturation detection sampling device comprises the following steps:

[0050] Step 1: When sampling, move the working frame 1 to the position where sampling is required, and then start the single-phase motor 301 to drive the rotating gear 304 to rotate through the rotating rod. When single-point or multi-point sampling is required, the fixed electromagnetic block 302 at the corresponding position will be triggered, so that the fixed electromagnetic block 302 at the corresponding position loses its magnetism, and the connecting magnetic plate 310 and the transmission gear 303 at the corresponding position lose their restraining force, and the movable installation rod 305 is driven to move downward through the movable spring 312 in a stretched state, and the transmission gear 303 is driven to move downward, so that the transmission gear 303 is meshed with the rotating gear 304, and the transmission gear 303 is driven to rotate, which drives the rotating screw 308 to rotate in the inner cavity of the moving slide 307, and drives the moving slider 306 to move inside the moving slide 307. When the moving slider 306 moves inside the moving slide 307, it contacts the positioning touch switch 309 at the corresponding position, and an alarm is sounded through the alarm outside the control panel to tell the staff the depth of the material when taking the material;

[0051] Step 2: Drive the fixed block 501 to move downward by moving the slider 306, which drives the sampling cylinder 401 to move downward. When the sampling cylinder 401 moves downward, it passes through the material taking through hole 9 and contacts the soil. When the sampling cylinder 401 continues to move downward, it will contact and squeeze the soil, moving the soil into the sampling cylinder 401. When the sampling cylinder 401 moves downward, it will squeeze the material taking guide bar 402 into the soil, so as to squeeze and limit the soil, and the limiting inclined groove 403 squeezes and fixes the sampled soil. During the sampling process, the air at the upper end of the sampling cylinder 401 is conveyed into the movable through hole 407. When the air flow flows in the inner cavity of the movable through hole 407, it contacts the push sleeve 408, pushing the push sleeve 408 to move upward, which drives the mounting ring bar 409 to move upward and drives the mounting slide bar 411 to slide in the mounting chute 410, increasing the stability when the mounting ring bar 409 and the push sleeve 408 move. When the mounting slide bar 411 moves, it squeezes the compression spring 413. Later, the compressed compression spring 413 drives the mounting slide bar 411, the mounting ring bar 409 and the push sleeve 408 to reset. When the mounting slide bar 411 moves, it drives the communication guide block to move. When the communication guide block slides upward outside the coil 412, the resistance of the single-phase motor 301 is reduced, improving the efficiency of the single-phase motor 301, and triggering the alarm light arranged outside the control panel to give an alarm. When the density of the sampled soil is greater, the air pressure formed at the upper end of the sampling cylinder 401 during sampling will be greater, so the driving force generated on the push sleeve 408 will be greater, and the resistance of the single-phase motor 301 during operation will be smaller. When the water content of the soil during sampling is too high, the liquid will flow into the limiting inclined groove 403 and gather at the bottom end inside the limiting inclined groove 403, causing the two connecting guide blocks 405 to be connected, and triggering the alarm arranged outside the control panel to give an alarm. After the material taking is completed, start the electric push rod 503 to drive the fixed cross bar 515 to move downward, drive the extrusion ejector rod 406 to move downward, and drive one side of the limiting block 504 to move downward with the hinge as the axis. When moving, it drives the docking slider 418 to slide in the moving chute 417, so that the limiting block 504 contacts and squeezes the bottom end of the sampling body, which can not only cut off the bottom end of the sampled body, but also limit and fix the sampled body, increasing the integrity of the sampled body during sampling. When the limiting block 504 contacts and squeezes the bottom end of the sampled body, when there is too much liquid in the sampled body, the liquid in the sampled body is squeezed into the receiving notch 414 through the extrusion filter plate 415, and the liquid gathers at the bottom end inside the receiving notch 414, and triggers the liquid level touch switch 416 to start the alarm arranged outside the control panel to give an alarm;

[0052] Step 3: When the sampling is completed and the test is performed, the electric push rod 503 is started to drive the fixed cross bar 515 to move downward, and the reset spring rod 516 is squeezed. Later, the fixed cross bar 515 is driven to move upward and reset through the reset spring rod 516 after squeezing, and the extrusion ejector rod 406 and the movable ejector rod 507 are driven to move upward and reset, and the movable ejector rod 507 is driven to move downward through the fixed cross bar 515, and the extrusion ejector ball 506 is driven to move downward, so that the extrusion ejector ball 506 contacts the inclined surface of the movable inclined block 508, and the movable inclined block 508 is pushed to move to the side of the installation slot 509, and the installation spring 511 is squeezed. , and later on, the installation spring 511 after extrusion can drive the movable inclined block 508 and the extrusion rod 512 to reset. When the movable inclined block 508 moves, it drives the extrusion rod 512 to slide inside the movable hole, and then drives the detection head 513 to move inside the movable hole, so that the detection head 513 and the sealing rubber ring 514 are stretched open, so that the extrusion rod 512 and the detection head 513 are inserted into the sample body, and the detection instrument 8 is started to detect the sample body. When the extrusion rod 512 and the detection head 513 are inserted into the sample body, the volume of the sample body expands, thereby increasing the fit between the sample body and the inner cavity of the sampling tube 401.

A detection method for detecting the ripening of undisturbed soil on sloping cultivated land by a sampling device, characterized in that, The detection method of the detection and sampling device is applicable to a device for detecting and sampling the original soil ripening of sloping cultivated land as described in claim 6, and includes the following steps: Step 1: When sampling, the working frame (1) is moved to the position where sampling is required, and then the single-phase motor (301) is started to drive the rotating gear (304) to rotate through the rotating rod. When single-point or multi-point sampling is required, the fixed electromagnetic block (302) at the corresponding position is triggered, so that the fixed electromagnetic block (302) at the corresponding position loses its magnetism, and the connecting magnetic plate (310) and the transmission gear (303) at the corresponding position lose their restraining force, and the movable installation rod (305) is driven to move downward through the movable spring (312) in a stretched state, and the movable installation rod (305) is driven to move downward. The driving gear (303) moves downward, so that the driving gear (303) meshes with the rotating gear (304), driving the driving gear (303) to rotate, thereby driving the rotating screw (308) to rotate in the inner cavity of the moving slide cylinder (307), and driving the moving slider (306) to move inside the moving slide cylinder (307). When the moving slider (306) moves inside the moving slide cylinder (307), it contacts the positioning touch switch (309) at the corresponding position, and an alarm is sounded through the alarm outside the control panel to inform the staff of the depth of the material when taking out; Step 2: Drive the fixed block (501) to move downward by moving the slider (306), which drives the sampling cylinder (401) to move downward. When the sampling cylinder (401) moves downward, it passes through the material taking through hole (9) and contacts the soil. When the sampling cylinder (401) continues to move downward, it will contact and squeeze the soil, moving the soil into the sampling cylinder (401). When the sampling cylinder (401) moves downward, the material taking guide bar (402) will be squeezed into the soil, squeezing the soil. During the sampling process, the air at the upper end of the sampling cylinder (401) is delivered into the movable through hole (407). When the air flow flows in the inner cavity of the movable through hole (407), the air flow contacts the push sleeve (408), pushing the push sleeve (408) to move upward, which drives the mounting ring bar (409) to move upward and drives the mounting slide rod (411) to slide inside the mounting chute (410), increasing the stability when the mounting ring bar (409) and the push sleeve (408) move. When the mounting slide rod (411) moves, it squeezes the compression spring (413). Later, the compressed compression spring (413) drives the mounting slide rod (411), the mounting ring bar (409) and the push sleeve (408) to reset. When the mounting slide rod (411) moves, it drives the communication guide block to move. When the communication guide block slides upward outside the coil (412), the resistance of the single-phase motor (301) is reduced, improving the efficiency of the single-phase motor (301), and triggering the alarm light arranged outside the control panel to give an alarm. When the density of the sampled soil is greater, the air pressure formed at the upper end of the sampling cylinder (401) during sampling will be greater, so the driving force generated on the push sleeve (408) will be greater, and the resistance of the single-phase motor (301) during operation will be smaller. When the water content of the soil during sampling is too high, the liquid will flow into the limiting inclined groove (403) and accumulate at the bottom end inside the limiting inclined groove (403), causing the two communication guide blocks (405) to be connected and triggering the alarm outside the control panel to give an alarm. After the material taking is completed, start the electric push rod (503) to drive the fixed cross bar (515) to move downward, drive the extrusion ejector rod (406) to move downward, and drive one side of the limiting block (504) to move downward with the hinge as the axis. When moving, it drives the docking slider (418) to slide inside the moving chute (417), making the limiting block (504) contact and squeeze the bottom end of the sampling body, which can not only cut off the bottom end of the sampled sample body, but also limit and fix the sample body, increasing the integrity of the sample body during sampling. When the limiting block (504) contacts and squeezes the bottom end of the sample body, when there is too much liquid in the sample body, the sample body is squeezed by the extrusion filter plate (415). When the sample body is subjected to the extrusion force, the liquid inside the sample body is squeezed into the receiving notch (414) through the filter holes inside the extrusion filter plate (415), so that the sample body particles inside the sample body will not move into the receiving notch (414), and the liquid converges at the bottom end inside the inner cavity of the receiving notch (414).and trigger the liquid level touch switch (416) to start the alarm configured outside the control panel for alarm; Step 3: When the sampling is completed and the test is performed, the electric push rod (503) is started to drive the fixed cross bar (515) to move downward, and the reset spring rod (516) is squeezed. Later, the reset spring rod (516) after squeezing drives the fixed cross bar (515) to move upward and reset, and drives the extrusion ejector rod (406) and the movable ejector rod (507) to move upward and reset, and drives the movable ejector rod (507) to move downward through the fixed cross bar (515), and drives the extrusion ejector ball (506) to move downward, so that the extrusion ejector ball (506) contacts the inclined surface of the movable inclined block (508), and pushes the movable inclined block (508) to move toward the side of the installation slot (509), and squeezes the installation spring (511), and then The installation spring (511) after being squeezed can be used to drive the movable inclined block (508) and the squeezing rod (512) to reset. When the movable inclined block (508) moves, it drives the squeezing rod (512) to slide inside the movable hole, thereby driving the detection head (513) to move inside the movable hole, so that the detection head (513) contacts and squeezes the sealing rubber ring (514), thereby expanding the sealing rubber ring (514), so that the squeezing rod (512) and the detection head (513) are inserted into the sample body, and the detection instrument (8) is started to detect the sample body. When the squeezing rod (512) and the detection head (513) are inserted into the sample body, the volume of the sample body expands, thereby increasing the fit between the sample body and the inner cavity of the sampling tube (401).
