Whether the collected samples are representative directly affects the accuracy and precision of the test analysis, and is an important prerequisite for whether the test results can truly reflect the soil environmental conditions. Before soil sampling, the profile should be repaired and cleaned, the top layer of loose soil should be removed, and then samples should be taken from the central typical part layer by layer from bottom to top.

[0016] Preferably, a protrusion is provided at one end of the rotating sleeve rod away from the sliding rod, and the protrusion can interfere with the rotating groove.

[0017] A method for installing an environmentally friendly soil collector comprises the following steps:

By using the movement of the movable component, the air pressure in the ventilation groove can be changed to adjust the mud discharge efficiency in the mud discharge chamber. At the same time, the collision between the movable component and the constraint shell is used to ensure the normal movement and sampling of the constraint shell in the soil, thereby further improving the collection efficiency of the collector.

[0030] 2. During the process of soil sampling and collection, the position of the supplementary plate is regulated according to the softness of the collected soil through the constraint shell to ensure that the collected soil sample is always located in the sampling cavity.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] On the one hand, if Figure 1-Figure 2 As shown, an environmentally friendly soil sample collector includes an operating component 1, wherein the operating component 1 is used as a handheld device for manual control and is also convenient for use as a bearing part when the soil sample collector is installed. One end of the operating component 1 is connected to a connecting component 3, and the connecting component 3 is used to realize the connection between the operating component 1 and the working component 4, so as to ensure that the working component 4 can meet the soil collection requirements at a deeper position. A movable component 2 is slidably provided on the outer circumference of the connecting component 3, wherein the working component 4 is struck by the movement of the movable component 2, so as to ensure that the working component 4 can reach the target soil depth at a faster rate. The end of the connecting component 3 away from the operating component 1 is connected to the working component 4, and the soil sample is collected by using the working component 4, wherein the soil sample collector can be stored in a storage box when it is not connected.

[0043] The connection component 3 includes a connection shell 301, wherein the connection shell 301 is detachably connected to the positioning disk 101, so as to realize the position constraint of the connection component 3, a bearing cavity 303 is opened in the connection shell 301, and a ventilation groove 302 is opened in the cavity wall of the bearing cavity 303, and an air hole 304 is opened on the side of the ventilation groove 302 close to the operating component 1, and the ventilation groove 302 and the air hole 304 are set to ensure that when there is soil in the mud discharge cavity 402, the air flow disturbance of the air hole 304 and the ventilation groove 302 can be used to regulate the soil transportation efficiency inside the mud discharge cavity 402, and at the same time, when the mud discharge rate of the mud discharge groove 404 is slow, resulting in the mud discharge cavity 402 being blocked by soil, the blockage of the mud discharge groove 404 can also be cleared through the mutual cooperation of the air hole 304 and the ventilation groove 302, so as to avoid the accumulation of soil inside the mud discharge cavity 402 and affect the use of the collector.

[0044] like Figure 3-Figure 4 As shown, the working component 4 includes a constraint shell 401, wherein the end of the constraint shell 401 away from the connecting component 3 is wedge-shaped, thereby ensuring that the constraint shell 401 can pierce the soil layer, and a sampling cavity 403 is provided through the constraint shell 401, wherein the sampling cavity 403 is used to collect soil samples, wherein when collecting soil samples, in order to avoid the constraint shell 401 from squeezing the edge of the soil sample and affecting the accuracy of the soil sample data, while the sampling cavity 403 is sampling the soil, the friction resistance between the constraint shell 401 and the soil is reduced, and then a mud outlet cavity 402 is opened in the cavity wall of the sampling cavity 403, and the soil at the edge of the sampling cavity 403 is transported through the mud outlet cavity 402, thereby reducing the soil squeezing force inside the sampling cavity 403, ensuring that the sampling cavity 403 samples the soil normally, and the mud outlet cavity 402 is close to the connecting shell 3. 01 is provided with a mud outlet groove 404, and a mud inlet groove 405 is provided on the side of the mud outlet cavity 402 away from the connecting shell 301, and the mud inlet groove 405 is connected with the sampling cavity 403. When the sampling cavity 403 is sampling the soil, the soil in the sampling cavity 403 first enters the mud outlet cavity 402 through the mud inlet groove 405, and then with the movement of the sampling cavity 403, the soil is finally moved out through the mud outlet groove 404, thereby ensuring the normal sampling of the sampling cavity 403. In order to facilitate the mud inlet groove 405 to scrape off the excess soil inside the sampling cavity 403, the groove shape of the mud inlet groove 405 is set to a parallelogram shape, and the side of the mud inlet groove 405 close to the sampling cavity 403 is a sharp end, so that when the soil passes through, the excess soil can be cut by the cavity wall of the sampling cavity 403, thereby improving the sampling efficiency.

[0045] It should be noted that after the soil passes through the mud outlet cavity 402, it cannot enter the ventilation groove 302, thereby preventing the ventilation groove 302 from being blocked, that is, a breathable membrane is connected between the mud outlet cavity 402 and the ventilation groove 302 to ensure the normal passage of gas while effectively preventing the soil from entering the ventilation groove 302.

[0046] Furthermore, in the process of the collector sampling the soil, the working component 4 is first brought into contact with the target ground, so that the user presses to cause the constraint shell 401 to move into the soil, causing the soil to enter the sampling cavity 403, and as the constraint shell 401 continues to penetrate, the movement of the movable component 2 is controlled to collide with the working component 4, ensuring that the constraint shell 401 can move inside the soil. At the same time, the soil at the edge of the sampling cavity 403 is cut by the mud inlet trough 405 to avoid mutual squeezing between the soil inside the sampling cavity 403 and the cavity wall of the sampling cavity 403, thereby affecting the accuracy of the soil sample data.

[0047] The shape of the movable component 2 is preferably an annular body, and when the movable component 2 moves on the connecting shell 301, its control method can be manual control, electromagnetic control or other methods that are convenient for controlling the movement.

[0048] In order to ensure that the soil is always located in the sampling chamber 403 during the process of sampling the soil in the sampling chamber 403, further, the carrying chamber 303 and the sampling chamber 403 are interconnected to ensure that the telescopic component 5 can be telescopically regulated in the collector, and a telescopic component 5 is connected to the carrying chamber 303 and the sampling chamber 403, one end of the telescopic component 5 is connected to the operating component 1, and a resistance component 6 is rotatably arranged in the telescopic component 5, wherein one end of the resistance component 6 is located in the sampling chamber 403, and then when a soil sample enters the sampling chamber 403, the soil sample can resist one end of the resistance component 6, and then as the soil sample moves in the sampling chamber 403, the resistance component 6 is driven to move, prompting the telescopic component 5 to be compressed, on the one hand ensuring that the soil is always in the sampling chamber 403, and on the other hand maintaining the soil in the sampling chamber 403. The moving speed of the soil is stable, and there will be no abnormal protrusion due to debris in the soil, thereby ensuring that the data of the soil sample will not be damaged.

[0049] like Figure 5As shown, the air hole 304 and the mud outlet groove 404 are connected to the outside of the collector, and the mud outlet chamber 402 is connected to the ventilation groove 302, wherein the movable component 2 can control the opening and closing of the air hole 304. When the movable component 2 moves back and forth on the air hole 304, the opening and closing of the air hole 304 by the movable component 2 can control the change of gas pressure in the ventilation groove 302. The change of gas pressure can cause the soil in the mud outlet chamber 402 to be in a relatively compact state. At the same time, in this process, the movement of the movable component 2 is utilized to realize the effect of gas suction in the ventilation groove 302, thereby ensuring that the soil in the mud outlet chamber 402 can be discharged through the mud outlet groove 404, and no blockage will occur in the mud outlet chamber 402.

[0050] like Figure 3-Figure 5 As shown, in order to improve the splicing efficiency of the working component 4 before use, the working component 4 further includes a docking sleeve 406, one end of which is fixedly connected to the constraint shell 401, and the docking sleeve 406 is threadedly connected to the connecting shell 301, wherein the connecting shell 301 is provided with a thread adapted to the docking sleeve 406, and then when in use, by rotating the constraint shell 401 and the docking sleeve 406, the working component 4 and the connecting component 3 are spliced ​​into a whole, which is convenient for soil sample sampling, and the mud cavity 40 2 penetrates the docking sleeve 406, and then after the docking sleeve 406 is connected to the connecting shell 301, the mud discharge chamber 402 is communicated with the ventilation groove 302. At the same time, in order to avoid a gap at the docking position of the mud discharge chamber 402 and the ventilation groove 302, a rubber gasket is connected at the position where the mud discharge chamber 402 and the ventilation groove 302 are connected to each other. When the docking sleeve 406 is docked, the two rubber gaskets are in contact with each other, and the movement of the docking sleeve 406 drives the two rubber gaskets to squeeze each other, ensuring that no leakage occurs at the interface position.

[0051] The gas flow mode in the ventilation groove 302 and the movement mode of the soil in the mud discharge cavity 402 can be directly referred to Figure 8 .

[0052] like Figure 1As shown, in order to facilitate the operator to control the collector and constrain the position of the working component 4, further, the operating component 1 includes a positioning disk 101, wherein the positioning disk 101 serves as a carrier to limit the position of other devices of the collector to ensure that the collector can be used normally, and the end of the connecting shell 301 away from the constraint shell 401 is detachably connected to one end of the positioning disk 101, wherein the detachable connection method includes but is not limited to threaded connection, plug-in and other methods that facilitate the quick connection of the connecting shell 301 and the positioning disk 101, and the end of the positioning disk 101 away from the connecting shell 301 is movably provided with a rotating groove 102, and the rotating groove 102 penetrates the positioning disk 101, wherein the rotating groove 102 can be connected with the protrusion at the bottom of the rotating sleeve rod 603, and when the rotating sleeve rod 603 needs to be rotated, the rotation of the rotating sleeve rod 603 can be achieved by controlling the rotation of the rotating groove 102, and the peripheral side of the positioning disk 101 is connected with a support rod 103, and the support rod 103 is used for the operator to hold.

[0053] In this solution, in order to facilitate the rotation of the rotating groove 102 and prevent the rotating groove 102 from rotating when it is not needed, the rotating groove 102 is set to be a card slot shape. When the rotating sleeve rod 603 needs to be rotated, a tool is used to engage with the rotating groove 102 and rotate it.

[0054] like Figure 6 As shown, in order to ensure that the telescopic assembly 5 can be retracted and will not interfere with the movement of the bearing plate 601 when the bearing plate 601 moves with the soil sample, the telescopic assembly 5 further includes a sleeve 501, one end of which is fixedly provided with a threaded tube 503, wherein the threaded tube 503 can be threadedly connected to the binding plate 101 to ensure that the position of the sleeve 501 will not move during use, the threaded tube 503 is threadedly connected to the binding plate 101, and the sleeve 501 is away from the threaded tube. A movable rod 502 is slidably provided at one end of the corrugated tube 503, and a cavity 504 is opened through the tube sleeve 501 and the movable rod 502, and the movable rod 502 can slide in the cavity 504 of the tube sleeve 501, and then when the supporting plate 601 moves in the sampling cavity 403, it can drive the movable rod 502 to move in the tube sleeve 501, and the resistance component 6 is rotatably connected in the cavity 504, and then when the resistance component 6 rotates, it will not affect the working state of the telescopic component 5.

[0055] like Figure 7As shown, in the process of sampling the soil, due to the different moisture and composition of the collected soil, it is easy for the resistance component 6 to fail to effectively press the soil. Furthermore, the resistance component 6 includes a carrier plate 601, wherein the carrier plate 601 is a fixed plate, that is, the carrier plate 601 is always in contact with the soil in the sampling cavity 403 regardless of the condition of the soil, and the carrier plate 601 is fixedly connected to the movable rod 502, that is, the carrier plate 601 will not rotate with the movable rod 502, and a supplementary plate 602 is rotatably provided on the carrier plate 601, wherein the supplementary plate 602 is stored in the carrier plate 601 when not in use, and when the supplementary plate 602 needs to be used, the supplementary plate 602 can be rotated out by rotating the rotating sleeve rod 603, thereby achieving The diameter of the bearing plate 601 is expanded to meet the resistance of the bearing plate 601 to the soil. A rotating sleeve rod 603 is rotatably provided in the cavity 504. A sleeve cavity 6031 is opened in the rotating sleeve rod 603. A sliding rod 604 is movably provided in the sleeve cavity 6031, that is, the sliding rod 604 can slide in the sleeve cavity 6031, but at the same time, the sleeve cavity 6031 can positionally constrain the circumference of the sliding rod 604 to prevent relative sliding between the sliding rod 604 and the sleeve cavity 6031, thereby ensuring that when the rotating sleeve rod 603 rotates, the sliding rod 604 can also rotate with the rotating sleeve rod 603. The sliding rod 604 penetrates the bearing plate 601 and is connected with the supplementary plate 602. At the same time, the rotation of the sliding rod 604 can control the screwing out and screwing in of the supplementary plate 602.

[0056] If necessary, a return spring can be arranged in the cavity 504, and one end of the return spring is connected to the pipe sleeve 501, and the other end is connected to one end of the movable rod 502. The return spring is located on the outer circumference of the rotating sleeve rod 603 and does not contact the rotating sleeve rod 603. When the soil sample needs to be removed, it can be adjusted with the help of the elastic force of the return spring, and return springs with different elastic coefficients can be selected according to different soil conditions. That is, when the soil is harder, the elastic coefficient of the return spring is larger, and vice versa.

[0057] like Figure 1 As shown, further, the cross-sectional area of ​​the connecting shell 301 is smaller than the cross-sectional area of ​​the constraining shell 401, and when the movable component 2 slides on the connecting shell 301, it can come into relative conflict with the constraining shell 401, and then when the constraining shell 401 has difficulty in diving, the constraining shell 401 can be knocked by moving the movable component 2 to ensure that the constraining shell 401 can dive to the target depth that needs to be measured.

[0058] like Figure 7As shown, further, a protrusion is provided at one end of the rotating sleeve rod 603 away from the sliding rod 604, and the protrusion can interfere with the rotating groove 102, that is, a groove adapted to the rotating sleeve rod 603 is provided on the rotating groove 102, thereby ensuring that when the rotating groove 102 is rotated, the rotating sleeve rod 603 can be rotated, thereby realizing the screwing out or screwing in of the supplementary plate 602, so as to realize the diameter change control of the supporting plate 601.

[0059] It should be noted that during the use of the soil sample collector, in order to ensure the verticality of the soil collection position, if necessary, auxiliary instruments can be used to constrain the position of the soil sample collector, wherein the auxiliary instruments are preferably brackets and ring plates, and the bracket can be used to level the ring plate, and the ring plate can limit the circumference of the working component 4, thereby avoiding errors in soil samples due to staff errors.

[0060] During operation, the soil sample collector is first moved to the target area and assembled in sequence, so that the operator can hold the operating component 1 to operate, ensuring that the soil sample can be collected.

[0061] The constraint shell 401 is placed at the soil position to be sampled and inserted into the soil layer. At the same time, the operator presses the constraint shell 401 by holding the handle 103, so that the constraint shell 401 penetrates into the soil layer, and the sampled soil is moved into the sampling cavity 403. At the same time, as the constraint shell 401 continues to move in the soil, the soil inside the sampling cavity 403 will enter the mud outlet cavity 402 through the cutting of the mud inlet groove 405, and as the constraint shell 401 continues to move, the soil in the mud outlet cavity 402 will be The soil moves and is discharged from the mud outlet trough 404, ensuring that the soil in the sampling cavity 403 will not be squeezed by the constraint shell 401, ensuring the accuracy of the soil sampling data. At the same time, when the soil in the sampling cavity 403 moves, the soil can contact with the supporting plate 601 and drive the supporting plate 601 to move, and at the same time drive the movable rod 502 and the sliding rod 604 to move, so as to ensure the normal movement of the soil in the sampling cavity 403, and prevent the soil sample from entering the supporting cavity 303 and being unable to be taken out.

[0062] At the same time, during the operation of the sampling chamber 403 and the mud outlet chamber 402, the movable component 2 is controlled to move back and forth on the connecting component 3 to realize the reciprocating opening and closing control of the air hole 304. At this time, since the mud outlet groove 404 is blocked by the soil, the ventilation groove 302 forms a relatively closed chamber, thereby realizing the control of the air pressure in the ventilation groove 302, realizing the reciprocating control of pressurization and decompression, and when the air pressure in the ventilation groove 302 changes, the soil inside the mud outlet chamber 402 can be sucked, that is, when the movable component 2 blocks the air hole 304, the air pressure inside the ventilation groove 302 increases, thereby causing the soil in the mud outlet chamber 402 to be contracted and squeezed, ensuring that the soil in the mud outlet chamber 402 is The soil is in a relatively compact state, which is convenient for the soil to move in the mud outlet cavity 402. When the movable component 2 is moved out from the air hole 304, the air pressure in the ventilation groove 302 is instantly reduced, thereby forming a negative pressure, which accelerates the movement of the soil in the mud outlet cavity 402 to prevent the soil from being blocked in the mud outlet cavity 402 and affecting the rate at which the constraint shell 401 enters the soil. In this process, due to the effect of the ventilation groove 302, the side of the mud outlet cavity 402 close to the mud inlet groove 405 is always in a loose state, ensuring that as the constraint shell 401 moves, the mud inlet groove 405 can always maintain the cutting of the soil in the sampling cavity 403. It should be noted that in this process, the soil will not enter the ventilation groove 302.

[0063] At the same time, when the movement of the constraint shell 401 in the soil is blocked, the movable component 2 is regulated to move, and in this process, the movable component 2 is controlled to collide with the constraint shell 401, and then the impact force of the movable component 2 is used to prompt the constraint shell 401 to move in the soil. In the process of the movable component 2 colliding with the constraint shell 401, the movable component 2 still regulates the air pressure change of the pore 304, so as to empty the soil in the mud outlet cavity 402, so that when the movable component 2 knocks on the constraint shell 401, the soil near the mud inlet groove 405 will not interfere with the soil entering the sampling cavity 403, so as to maintain the normal sampling of the sampling cavity 403.

[0064] At the same time, the state of the supplementary plate 602 is adjusted according to the state of the soil sample collected. When the soil has low humidity and high hardness, the supplementary plate 602 is located in the carrier plate 601 and is not unfolded. When the soil has high humidity and low hardness, the rotating groove 102 is rotated to control the rotation of the rotating sleeve rod 603 and the sliding rod 604 to rotate, so as to realize relative rotation between the supplementary plate 602 and the carrier plate 601, so as to cause the supplementary plate 602 to rotate out and supplement the diameter of the carrier plate 601. When the soil tends to be fluid, the supplementary plate 602 is regulated to be fully unfolded so that the supplementary plate 602 completely conflicts with the cavity wall of the sampling cavity 403, thereby avoiding the soil from crossing the carrier plate 601 and causing inaccurate sampling data.

[0065] By setting the mutual coordination among the movable component 2, the ventilation groove 302 and the mud discharge chamber 402, it is ensured that during the sampling process of the sampler, the sampling chamber 403 can effectively sample the soil, and during the sampling process, the setting of the mud discharge chamber 402 can prevent the soil sample from being squeezed in the sampling chamber 403 to affect the sampling accuracy, and by utilizing the movement of the movable component 2, the air pressure in the ventilation groove 302 can be changed to adjust the mud discharge efficiency in the mud discharge chamber 402, and at the same time, the collision between the movable component 2 and the constraint shell 401 is utilized to ensure the normal movement and sampling of the constraint shell 401 in the soil, thereby further improving the collection efficiency of the collector.

[0066] On the other hand, although the rapid sampling of the soil in the sampling cavity 403 is achieved by utilizing the mutual cooperation among the movable component 2, the ventilation groove 302 and the mud outlet cavity 402, at the same time, since the working component 4 needs to be removed after sampling, it is very easy for the soil to slip out of the sampling cavity 403 during the removal process due to the influence of its own gravity, resulting in sampling failure.

[0067] After the sampling chamber 403 completes sampling of the target soil, the collector needs to be removed from the soil. At this time, the movable component 2 is regulated to close the air hole 304, thereby increasing the air pressure in the ventilation groove 302, so that the air pressure in the ventilation groove 302 continues to pressurize the soil in the mud outlet chamber 402, causing the soil in the mud outlet chamber 402 to be squeezed and compressed, so that the soil in the mud outlet chamber 402 squeezes the constraint shell 401, thereby causing the soil in the mud outlet chamber 402 to resist and constrain the cavity wall of the sampling chamber 403, preventing the soil from slipping out of the sampling chamber 403 when the working component 4 is moved out of the soil. At this time, due to the limited soil content in the mud outlet chamber 402, when the soil is compressed in the mud outlet chamber 402, it will not cause damage to the soil sample in the sampling chamber 403, thereby ensuring the accuracy of the sampling effect.

[0068] The present invention also includes a method for installing an environmentally friendly soil collector, comprising the following steps:

[0069] S1, docking one end of the connecting shell 301 with the positioning disk 101;

[0070] S2, making the movable component 2 pass through one end of the connecting shell 301 and conflict with the connecting shell 301, while ensuring that the movable component 2 can slide on the outer circumference of the connecting shell 301;

[0071] S3, making one end of the telescopic assembly 5 and the abutting assembly 6 abut against the position plate 101, and then docking with the position plate 101 by rotating the threaded tube 503, and at the same time, the protrusion of the rotating sleeve rod 603 abuts and engages with the rotating groove 102;

[0072] S4, the telescopic component 5 and the abutting component 6 are located in the sampling cavity 403, and then the threaded connection is realized by rotating the docking sleeve 406 and the connecting shell 301, and finally the collectors are spliced ​​together to form a whole, so as to realize the collection of the target soil.

[0073] The present invention also includes a sample collection method of an environmentally friendly soil collector, comprising the following steps:

[0074] S1. The user holds the handle 103 so that one end of the restraining shell 401 contacts the ground, and at the same time, the user presses the collector;

[0075] S2, as the restraining shell 401 is pressed and moved into the soil, the soil is moved to the sampling cavity 403 for storage. When the soil moves in the sampling cavity 403, the mud inlet groove 405 cuts the edge of the soil in the sampling cavity 403, so that the excess soil enters the mud outlet cavity 402 and moves in the mud outlet cavity 402 as the restraining shell 401 moves;

[0076] S3, when the soil moves in the mud discharge cavity 402, the movable component 2 is controlled to slide on the connecting shell 301, and the opening and closing of the air hole 304 are controlled to realize the air pressure control in the ventilation groove 302;

[0077] S301, when the soil moves in the sampling cavity 403, the soil and the carrying plate 601 conflict with each other and drive the carrying plate 601 to move;

[0078] S4. When the movement of the restraining shell 401 is blocked, the movable component 2 moves and collides with the restraining shell 401 to maintain normal sampling of the sampling cavity 403, and the air pressure change of the ventilation groove 302 is used to suck the soil in the mud discharge cavity 402 to maintain the stability of the mud discharge of the mud discharge groove 404.
