Description

Technical Field

[0001] The present invention relates to the technical field of soil detection sampling, and more specifically, to a sampler, device and sampling method for soil salinization control. Background Art

[0002] In soil salinization control and contaminated site investigation, accurate and non-destructive sampling of soil layers is the basis for obtaining reliable detection data.

[0003] Existing samplers have the following problems: First, after sampling, the sample soil needs to be oscillated and poured out of the sampling tube by knocking the sampling tube, which easily causes soil particles to break and salt stratification to mix. Especially in loose or viscous soils, it is difficult to retain the original hierarchical structure. Second, for the integral sampling tube, the sample needs to be poured out of the sampling tube first before detecting the pH value, heavy metal content, etc., increasing the difficulty of detection operation. Third, the residue on the inner wall of the sampling tube is difficult to clean thoroughly, easily causing cross-contamination of samples and affecting the accuracy of subsequent sampling and detection. Summary of the Invention

[0004] The purpose of the present invention is to provide a sampler, device and sampling method for soil salinization control. Through the design of the adjustment disk and multiple track grooves, the step-by-step unfolding of the sampling plate is controlled, and the soil sample can be directly observed or detected, and the soil hierarchical structure at different depths is completely retained.

[0005] A sampler for soil salinization control includes a sampler body. The sampler body includes an adjustment frame, on which several sliders are slidably connected. The top end of the slider is fixedly installed with a lever, and the bottom end of the slider is fixedly installed with a sampling plate. An adjustment disk is rotatably arranged on the adjustment frame. The adjustment disk is provided with a first track groove, two sets of second track grooves and two sets of third track grooves that can be inserted and matched with the lever. A limit component for restricting the rotation of the adjustment disk is arranged on the adjustment frame.

[0006] When the adjustment disk rotates, the lever can move along the track groove respectively under the limitation of the first track groove, the second track groove and the third track groove, driving several sampling plates to unfold or close step by step, and several sampling plates can form a sampling cylinder when they are closed.

[0007] As a further description of the above technical solution, the two sets of second track grooves are distributed on both sides of the first track groove, and the two sets of third track grooves are distributed between the two sets of second track grooves and are not adjacent to the first track groove.

[0008] As a further description of the above technical solution, the first track groove, the second track groove and the third track groove all include an arc groove, a reversing groove and a turning groove that are sequentially connected.

[0009] The midlines of the turning grooves of the first track groove, the second track groove, and the third track groove are concentric circles, and the distance between the center of the turning groove and the adjusting disc is greater than the distance between the center of the arc groove and the adjusting disc.

[0010] As a further description of the above technical solution, the midlines of the arc grooves of the first track groove, the second track groove, and the third track groove are concentric circles, and the arc lengths of the arc grooves of the first track groove, the second track groove, and the third track groove increase in sequence.

[0011] As a further description of the above technical solution, the limiting component includes a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block arranged on the surface of the adjusting frame, and a spring pin that is installed on the adjusting disc and is in limiting cooperation with the first limiting block, the second limiting block, the third limiting block, and the fourth limiting block.

[0012] As a further description of the above technical solution, the soil salinization treatment sampler further includes a support pipe. A plurality of positioning grooves are arranged along the circumference at the top end of the support pipe, and fixing blocks that are inserted and matched with the positioning grooves are arranged on the outer wall of the sampling plate.

[0013] The present invention discloses a device for soil salinization treatment, including the above-mentioned soil salinization treatment sampler; and a sampling base. A telescopic cylinder is fixedly installed on the sampling base, the output end of the telescopic cylinder is fixedly connected to a lifting frame, and the adjusting frame is rotatably installed on the lifting frame through a support shaft.

[0014] As a further description of the above technical solution, a first guide groove and a second guide groove that are perpendicular to each other and communicate are formed on the sampling base;

[0015] A steering rod that can slide and cooperate in the first guide groove and the second guide groove is installed on the adjusting frame.

[0016] The present invention discloses a sampling method for a device for soil salinization treatment, including the following steps:

[0017] S1. Start the telescopic cylinder, and the output end of the telescopic cylinder drives the sampling cylinder in the closed state to insert into the soil layer for sampling through driving the adjusting frame;

[0018] S2. After sampling, drive the sampling cylinder and the soil sample to rise through the output end of the telescopic cylinder;

[0019] S3. Under the action of the second guide groove, the direction of the sampling cylinder rotates from the vertical state to the horizontal state; then rotate the adjusting disc to enable a plurality of sampling plates to be unfolded step by step and sample.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. Through the design of the adjusting disc and multiple track grooves, the present invention can control the phased unfolding of the sampling plate, enabling direct observation or detection of the soil samples in the sampling cylinder without pouring out or using tools to dig, and completely preserving the soil layer structure at different depths.

[0022] 2. When part of the sampling plate of the present invention unfolds, it can achieve fixed-point insertion of the sampling tube to extract samples from specific layers. When fully unfolded, it can force the soil to automatically fall off from the gaps between the sampling plates. The unfolded sampling plate is also convenient for cleaning, reducing the risk of sample cross-contamination and residue interference.

[0023] 3. Through the cooperation of the spring pin and four limit blocks, the present invention realizes the rapid switching among four modes of the sampling plate closing, single-layer unfolding, partial unfolding, and full opening, flexibly adapting to different operation requirements of on-site detection.

Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figure 1 shown, the present application discloses a sampler and device for soil salinization control, including a sampling base 11, a telescopic cylinder 12 is fixedly installed on the sampling base 11, the output end of the telescopic cylinder 12 is fixedly connected to a lifting frame 13, the side of the lifting frame 13 is slidably matched with a guide rod 14 installed on the sampling base 11 through a guide block, and a sampler body 2 is installed on the lifting frame 13; when the telescopic cylinder 12 is started, the output end of the telescopic cylinder 12 can drive the sampler body 2 to perform a lifting movement.

[0039] It should be noted that the sampling base 11 can be fixedly installed on a traction device or the robotic arm of a traction device, and the sampler is controlled by the traction device to move to the sampling point for sampling, reducing the sampling difficulty.

[0040] As Figures 1 - 4As shown, the sampler body 2 includes an adjustment frame 21. The adjustment frame 21 is rotatably connected to the lifting frame 13 through a support shaft 22. A number of through holes 23 are formed in the adjustment frame 21. Guide rails 24 are fixedly installed in the through holes 23. A slider 25 is slidably connected to the guide rails 24. A lever 26 is fixedly installed at the top end of the slider 25. The bottom end of the slider 25 passes through the through hole 23 and is fixedly installed with a sampling plate 27. During the process of the slider 25 sliding on the guide rail 24, a number of sampling plates 27 can be unfolded or closed, and a number of sampling plates 27 can form a sampling cylinder when closed. A steering rod 29 is arranged on the adjustment frame 21. A first guide groove 31 and a second guide groove 32 that are perpendicular to each other and communicate are formed in the sampling base 11. The steering rod 29 can slide and be guided in the first guide groove 31 and the second guide groove 32 in a matching manner.

[0041] As Figure 1 shown, the direction in which the first guide groove 31 is formed is parallel to the guide rod 14, and the direction in which the second guide groove 32 is formed is perpendicular to the guide rod 14. When the steering rod 29 moves in the first guide groove 31, the moving direction of the sampler body 2 can be the same as the moving direction of the lifting frame 13, which is convenient for the sampler body 2 to be inserted into the soil for sampling or to extract the sampled soil from the soil layer; when the steering rod 29 is transferred from the first guide groove 31 into the second guide groove 32, or from the second guide groove 32 into the first guide groove 31, the sampler body 2 can be switched from a vertical state to a horizontal state, or from a horizontal state to a vertical state, so as to achieve a 90-degree switch. Switching to the horizontal state is convenient for subsequent sample soil analysis, collection and unloading.

[0042] As Figure 1 、 Figures 5 to 10 As shown, an adjustment disk 4 is rotatably arranged on the adjustment frame 21. The through holes 23 are distributed in an array around the axis of the adjustment disk 4; a first track groove 41, two groups of second track grooves 42 and two groups of third track grooves 43 are formed in the adjustment disk 4. The first track groove 41, two groups of second track grooves 42 and two groups of third track grooves 43 are circularly distributed around the axis of the adjustment disk 4. The two groups of second track grooves 42 are distributed on both sides of the first track groove 41. The two groups of third track grooves 43 are distributed between the two groups of second track grooves 42 and are not adjacent to the first track groove 41. When the adjustment disk 4 rotates, the lever 26 can move along the track groove respectively under the limitation of the first track groove 41, the second track groove 42 and the third track groove 43, and can drive a number of sampling plates 27 to be unfolded or closed step by step.

[0043] Among them, the first track groove 41, the second track groove 42, and the third track groove 43 all include an arc groove 44, a reversing groove 45, and a steering groove 46 that are connected in sequence. The midlines of the arc grooves 44 and the steering grooves 46 of the first track groove 41, the second track groove 42, and the third track groove 43 are concentric circles, and the distance from the steering groove 46 to the center of the adjustment disk 4 is greater than the distance from the arc groove 44 to the center of the adjustment disk 4. The arc lengths of the arc grooves 44 of the first track groove 41, the second track groove 42, and the third track groove 43 increase in sequence, and the arc lengths of the steering grooves 46 of the first track groove 41, the second track groove 42, and the third track groove 43 decrease in sequence.

[0044] Specifically, when manually controlling the adjustment disk 4, when the shift lever 26 in the first track groove 41 moves in the reversing groove 45, the corresponding shift levers 26 in the second track groove 42 and the third track groove 43 are both located in the arc groove 44; when the shift lever 26 in the first track groove 41 moves to the reversing groove 45 and the steering groove 46, the shift lever 26 in the second track groove 42 begins to enter the reversing groove 45, and the shift lever 26 in the third track groove 43 remains in the arc groove 44; when the shift lever 26 in the second track groove 42 moves a certain displacement in the reversing groove 45, the shift lever 26 in the third track groove 43 begins to enter the reversing groove 45. That is, by controlling the shift levers 26 in the first track groove 41, the second track groove 42, and the third track groove 43 to enter the reversing groove 45 at different times, the different unfolding sequences of each sampling plate 27 are controlled. After a group of sampling plates 27 are unfolded, the staff can directly observe information such as the color, salt distribution, and soil particle structure of the sampled soil, and can also directly detect the pH value and humidity parameters of the sampled soil through portable detection equipment, without taking the sampled soil out of the sampling cylinder, which is convenient for retaining the different depth layer structures of the soil, reducing particle breakage or loss caused by dumping or tool excavation, suitable for sampling loose or viscous soil, and the sampling personnel can also collect the collected soil at a fixed point by using a sampling tube to improve the accuracy of sampling.

[0045] When it is necessary to transport all the soil samples, manually rotate the adjustment disk 4 to unfold the sampling plate 27 corresponding to the second track groove 42, the sampling plate 27 corresponding to the first track groove 41 is in a fully unfolded state, and the sampling plate 27 corresponding to the third track groove 43 remains in a folded state. At this time, the sampling plate 27 corresponding to the second track groove 42 is separated from the soil sample. By manually pushing the top of one end of the sampled soil or using the top plate to closely adhere to one end of the sampled soil to assist in pushing, the soil is gradually pushed out of the sampling plate 27, and protective measures such as plastic wrap are wound around the soil on the pushing side of the soil for convenient transportation and storage. The unfolding of the sampling plates 27 corresponding to the first track groove 41 and the second track groove 42 can effectively reduce the resistance during soil sampling and improve the convenience of soil sampling.

[0046] When the sampled soil does not meet the sampling standard, simply manually rotate the adjustment disc 4 to make all the sampling plates 27 in an open state, and the soil can fall from the gaps between the sampling plates 27, realizing rapid unloading of the sampled soil. Moreover, the separable unfolding design of the sampling plates 27 also effectively reduces the cleaning difficulty of the inner walls of the sampling plates 27 and avoids secondary sampling pollution.

[0047] As Figure 3 and Figure 6 shown, in order to limit the rotation of the adjustment disc 4, the present application is sequentially provided with a first limit block 210, a second limit block 211, a third limit block 212, and a fourth limit block 213 on the adjustment frame 21. A spring pin 47 is installed on the adjustment disc 4, and the spring pin 47 can be inserted and matched with the first limit block 210, the second limit block 211, the third limit block 212, or the fourth limit block 213. Among them, the spring pin 47 includes a pin block slidably disposed on the adjustment disc 4, and an elastic member for pushing the pin block to move outward is installed on the adjustment disc 4, so that the pin block is elastically connected to the adjustment disc 4. Under the action of the elastic member, the pin block of the spring pin 47 is inserted into the limit block. When it is necessary to make the spring pin 47 disengage from the current limit block and insert into the next limit block, the operator manually pushes the pin block to compress the elastic member to make the pin block disengage from the current limit block, and then rotates the adjustment disc 4 to make the spring pin 47 rotate to correspond to the next limit block, and the pin head of the spring pin 47 is inserted into the next limit block under the action of the elastic member to realize the limit fixation of the adjustment disc 4.

[0048] Specifically, manually control the rotation of the adjustment disc 4 so that the spring pin 47 is inserted into the first limit block 210. At this time, several lever rods 26 are all located in the first arc-shaped groove 44, and several sampling plates 27 are in a closed state to form a sampling cylinder; manually control the rotation of the adjustment disc 4 so that the spring pin 47 is inserted into the second limit block 211. The lever rod 26 in the first track groove 41 moves to the communication position of the reversing groove 45 and the steering groove 46. Under the action of the reversing groove 45, the lever rod 26 corresponding to the first track groove 41 and the slider 25 slide outwards on the guide rail 24, and the sampling plate 27 corresponding to the first track groove 41 is fully unfolded. At this time, the lever rods 26 corresponding to the second track groove 42 and the third track groove 43 are still located in the first arc-shaped groove 44, and the sampling plates 27 corresponding to the second track groove 42 and the third track groove 43 do not move or unfold; when the spring pin 47 is inserted into the third limit block 212, the lever rod 26 in the third track groove 43 moves to the communication position of the arc-shaped groove 44 and the reversing groove 45. At this time, on the basis that the sampling plate 27 corresponding to the first track groove 41 is fully opened, the lever rod 26 corresponding to the second track groove 42 moves into the reversing groove 45, thereby driving the slider 25 to slide outwards on the guide rail 24 by a certain displacement, so that the sampling plate 27 corresponding to the second track groove 42 unfolds within a certain range but is not fully unfolded, which is convenient for the analysis and collection of soil samples; manually rotate the adjustment disc 4 so that when the spring pin 47 is inserted into the fourth limit block 213, the first track groove 41, the second track groove 42 and the third track groove 43 control the lever rod 26 and the slider 25 to slide outwards on the guide rail 24, thereby driving several sampling plates 27 to move and fully unfold.

[0049] It should be noted that when several sampling plates 27 rotate from the vertical state to the horizontal state, the sampling plate 27 corresponding to the first track groove 41 is located at the uppermost part of several sampling plates 27, ensuring the stability of the sampled soil and facilitating sampling when the sampling plate 27 is unfolded alone.

[0050] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 11 and Figure 12 When several sampling plates 27 are closed to form a sampling cylinder, a support pipe 5 is inserted into the outer wall of the sampling cylinder, so that the support pipe 5 abuts against the bottom of the adjusting frame 21; a tooth tip 51 is arranged at the bottom of the support pipe 5 to reduce the difficulty of inserting into the soil layer during sampling. Several positioning grooves 52 are arranged on the support pipe 5. A fixing block 28 is fixedly installed on the outer side of each sampling plate 27, and the fixing block 28 is inserted into the corresponding positioning groove 52. A limit pin passes through the positioning groove 52 and the fixing block 28 to fix the support pipe 5 on the sampling plate 27. By providing the support pipe 5, the stability of the sampling cylinder after being inserted into the soil layer can be ensured, and problems such as fracture caused by the outward expansion of each sampling plate 27 can be avoided.

[0051] The present invention also discloses a sampling method for a device for soil salinization control, including the following steps:

[0052] S1. Manually rotate the adjusting disk 4, insert the spring pin 47 into the first limiting block 210, close several sampling plates 27, insert the support tube 5 onto the closed sampling cylinder and fix it.

[0053] S2. Move the sampling base 11 to the sampling point to be sampled, start the telescopic cylinder 12, and the output end of the telescopic cylinder 12 drives the sampler body 2 to descend and gradually insert into the soil for sampling.

[0054] S3. After sampling is completed, the output end of the telescopic cylinder 12 drives the sampler body 2 to rise. The steering rod 29 moves upward in the first guiding groove 31 and switches to the second guiding groove 32. After the sampling cylinder rotates 90 degrees and is in a horizontal state, remove the limit pin and pull out the support tube 5 from the sampling cylinder.

[0055] S4. Manually switch the spring pin 47 from the first limiting block 210 and insert it into the second limiting block 211. The lever 26 in the first track groove 41 slides outward towards the outside of the adjusting disk 4, thereby driving the slider 25 and the corresponding sampling plate 27 to slide outward, realizing the upward unfolding of the corresponding sampling plate 27, and other sampling plates 27 remain closed. The sampling personnel conduct preliminary detection and analysis on the sampled soil.

[0056] S5. When the sampled soil meets the requirements, insert the sampling tube into the corresponding soil layer in the sampling cylinder for fixed-point sampling. After sampling is completed, switch the spring pin 47 to the fourth limiting block 213, and several sampling plates 27 are fully opened with respect to each other. The soil falls from the gaps between the sampling plates 27 and the inner walls of the sampling plates 27 are cleaned.

[0057] S6. When the sampled soil meets the requirements and all soil samples are needed, switch the spring pin 47 from the second limiting block 211 to the third limiting block 212. At this time, the sampling plate 27 corresponding to the second track groove 42 unfolds and separates from the soil surface, and the sampling plate 27 corresponding to the third track groove 43 still remains closed. Use tools to gradually push the soil out from the sampling plate 27 and wrap it for treatment, and then clean the sampling plate 27.

[0058] S7. When the preliminary detection of the sampled soil is unqualified, directly switch the spring pin 47 to the fourth limiting block 213, directly discharge the unqualified soil sample and clean the inner wall of the sampling plate 27.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
