Description

Technical Field

[0001] This invention belongs to the field of mineral geological exploration technology, specifically relating to a sampling and monitoring device and method based on the ecological spatial response relationship between coal and water. Background Technology

[0002] The coal-water-ecological spatial response relationship refers to the dynamic interaction mechanism formed in three-dimensional space between coal resource development activities (such as mining and washing) and regional hydrological systems (groundwater, surface water) and ecosystems (soil, vegetation, biodiversity, etc.). Specifically, it manifests as changes in geological structure, groundwater level decline or pollution, and changes in soil moisture content in the vadose zone caused by coal mining. Simultaneously, the deterioration of the water and soil environment can conversely constrain the feasibility of safe coal mining, forming a chain reaction. Its intensity is influenced by factors such as the scale of mining, geological conditions, and ecological background. To quickly understand the geological conditions of water bodies and soil during coal mining, sampling and monitoring equipment is frequently used for exploration, thereby providing monitoring and early warning for subsequent safe mining operations.

[0003] Chinese Patent Application No. 202411161777.6 discloses an automatic drilling device for groundwater or soil testing and sampling, comprising: a positioning plate with positioning rods installed at each of the four corners of its lower end; a lifting device connected to the upper end of the positioning plate; and a transmission device connected to the lifting device, the transmission device including a drive module connected to the lifting device, the lower end of the drive module being fixedly connected to a cylindrical frame, and multiple circumferentially evenly distributed snap-fit ​​mechanisms connected to the annular sidewall of the cylindrical frame. This patent utilizes a transmission device and extension device that allow for rapid assembly and disassembly, as well as rapid assembly and disassembly among the multiple extension devices, thereby effectively improving the speed of extension device assembly during drilling and thus increasing drilling efficiency.

[0004] When conducting soil sampling, inaccurate sampling direction often leads to depth errors, resulting in soil samples taken from depths other than the specified depth, rendering them meaningless. Furthermore, studies on the spatial response relationship between coal, water, and ecology typically require simultaneous sampling of water and soil samples for the data to be meaningful. However, during this simultaneous sampling, water sampling equipment is often contaminated during soil sampling, leading to inaccurate water composition in subsequent samples. Additionally, when sampling a specific soil layer for moisture content monitoring, the compression of the soil during sampling causes changes in sample volume and consequently, variations in moisture content. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sampling and monitoring device and method based on the ecological spatial response relationship between coal and water. Through the structural design of the coil and soil sampling cylinder, along with the coordination of the electric telescopic rod and positioning screw, this invention ensures that the soil sampling cylinder remains vertical even in complex terrain, thereby improving the accuracy of subsequent soil sampling and monitoring. Furthermore, through the cooperation of the soil sampling cylinder and the outer cylinder, under the control of the water sampling mechanism, this invention ensures that the soil sampling cylinder can be smoothly inserted into the soil while preventing the water sampling mechanism from being contaminated by the soil during insertion, thus avoiding interference with the accuracy of subsequent water body detection. This invention also greatly reduces the compression of the sampled soil during sampling and can quickly recover the soil in its original state, thereby minimizing interference with subsequent soil moisture content analysis and improving the accuracy of soil detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sampling and monitoring device based on the ecological spatial response relationship of coal and water includes a limiting frame, which includes a top plate and four supporting feet fixed around the top plate; a winding device is fixedly installed on the top of the top plate, the winding device includes a pair of supporting plates fixed on the top of the top plate, a winding drum is rotatably connected to the supporting plates, and a steel wire rope is fixedly wound on the winding drum; a wire-passing hole is opened through the middle of the top plate, and one end of the steel wire rope passes through the wire-passing hole and is fixedly connected to the soil sampling cylinder;

[0008] The soil sampling cylinder is rotatably connected to an outer cylinder. The support legs have two threaded holes at the top and bottom, and positioning screws are screwed into the threaded holes. The top plate has symmetrical through holes on both sides of the wire hole. An electric telescopic rod is fixedly installed on the top plate. The telescopic end of the electric telescopic rod passes through the through hole and abuts against the top of the soil sampling cylinder.

[0009] Furthermore, the soil sampling cylinder is formed by splicing two annular blocks to form a cylindrical structure. The upper ends of the two annular blocks together form a threaded opening, and a top cover is screwed onto the threaded opening. A limiting plate is fixedly provided on the top of the top cover, and an air hole communicating with the top cover is passed through the limiting plate. One end of the steel wire rope is fixedly connected to the middle of the limiting plate. A cutting tool is fixedly provided at the lower end of the annular block, and an outer ring block is fixedly provided around the upper end of the cutting tool.

[0010] Furthermore, the upper end of the outer cylinder is provided with a limiting port, and the limiting plate abuts against the upper part of the limiting port; the lower end of the outer cylinder is fixedly provided with a frustum-shaped end cylinder, and the lower end of the frustum-shaped end cylinder abuts against the outer ring block; a plurality of blades are evenly provided on the outer surface of the frustum-shaped end cylinder.

[0011] Furthermore, the frustum-shaped end cylinder has symmetrical switching slots on both sides, and an arc-shaped baffle is rotatably connected to the switching slot. The two ends of the arc-shaped baffle are fixed with rotating shafts, which are rotatably connected to the bottom ends of the switching slot. A torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are fixedly connected to the arc-shaped baffle and the switching slot, respectively. A plurality of second blades are evenly distributed on the outer surface of the arc-shaped baffle.

[0012] Furthermore, a water intake mechanism is provided between the soil sampling cylinder and the outer cylinder; the water intake mechanism includes a circular rod, and an L-shaped water intake pipe is symmetrically fixedly connected to the inner side of the circular rod. An end cap is screwed to the end of the L-shaped water intake pipe, and a water level alarm is installed at the center of the surface of the end cap; a water inlet is opened on the side wall of the L-shaped water intake pipe.

[0013] Furthermore, the outer cylinder has symmetrical vertical adjustment slots on its side wall, and the horizontal pipe of the L-shaped water intake pipe is slidably connected to the corresponding adjustment slot.

[0014] Furthermore, the adjusting groove is fixedly connected to the limiting groove, and a sliding hole is provided at the lower end of the limiting groove. The longitudinal tube of the L-shaped water intake pipe is slidably connected to the sliding hole. A return spring is sleeved on the longitudinal tube of the L-shaped water intake pipe, and the return spring is located inside the limiting groove.

[0015] Furthermore, the support plate has a rotating hole, and a rotating rod is rotatably connected to the rotating hole. The winding drum is installed on the rotating rod between the two support plates. A limiting block is fixed on the rotating rod, and the limiting block is located on the outside of the two support plates. A handle is fixed on one end of the rotating rod. A limiting mechanism for restricting the rotation of the rotating rod is installed on the top plate.

[0016] Furthermore, the positioning screw includes an upper positioning screw and a lower positioning screw, with the lower positioning screw located directly below the upper positioning screw; the telescopic end of the electric telescopic rod is fixedly provided with a push plate.

[0017] A method for operating the aforementioned sampling and monitoring equipment based on the spatial response relationship between coal and water ecosystems includes the following steps:

[0018] S1. Install and fix the support feet on the ground of the area to be tested. Then, after the outer cylinder is kept vertical by gravity, adjust the positioning screw to limit the outer cylinder, thereby keeping the soil sampling cylinder vertical.

[0019] S2. Release the limit of the rotating rod, and then start the electric telescopic rod to press the electric telescopic rod against the soil sampling cylinder, so that the soil sampling cylinder descends and inserts into the soil. When insertion is difficult, the soil cutting operation is performed by rotating the circular rod.

[0020] S3. When the soil sampling tube is inserted into the groundwater layer, press down the circular rod so that the L-shaped water sampling pipe presses against the arc-shaped baffle and extends out of the outer tube. The L-shaped water sampling pipe extends into the groundwater surface and the circular rod continues to rotate. Finally, the water enters the inlet for water sampling.

[0021] S4. Loosen the round rod, and the L-shaped water intake pipe returns to the inside of the outer cylinder. Then pull the rotating rod to rewind the wire rope. After the soil intake cylinder returns to the ground, press down the round rod to extend the end cap out of the outer cylinder. Then open the end cap to recover the water. Remove the limit frame, then open the top cover and pull the soil intake cylinder out in the direction of the insert knife to recover the soil.

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

[0023] (1) Through the structural design of the spool and the soil sampling tube, as well as the cooperation of the electric telescopic rod and the positioning screw, this invention can ensure that the soil sampling tube is always in a vertical state in complex terrain, thereby improving the accuracy of subsequent soil sampling and monitoring. Specifically, when a location is determined to be sampled for soil, the support foot is first installed and fixed on the ground of the area to be tested. At this time, the terrain does not need to be too complex, just ensure that the support foot is fixed on the ground. Then, after the outer tube is kept vertical by gravity, the positioning screw is adjusted to limit the outer tube. At this time, regardless of whether the limiting frame is vertical or not, the soil sampling tube is always in a vertical state. Under the joint limitation of the positioning screw on the upper and lower threaded holes, the extension of the electric telescopic rod can ensure that the soil sampling tube can always be inserted vertically into the soil, thereby improving the accuracy of subsequent soil sampling.

[0024] (2) This invention, through the cooperation of the soil sampling cylinder and the outer cylinder, under the control of the water sampling mechanism, can ensure that the soil sampling cylinder is smoothly inserted into the soil while preventing the water sampling mechanism from being contaminated by the soil during insertion, thus avoiding interference with the accuracy of subsequent water sampling detection. Specifically, when the soil sampling cylinder needs to be inserted for soil sampling, the limit of the rotating rod is released, and then the electric telescopic rod is activated to press against the soil sampling cylinder, causing the soil sampling cylinder to descend and be inserted into the soil. During this process, the water sampling mechanism is inside the outer cylinder, and the external soil will not contaminate the water sampling mechanism. When insertion encounters difficulties, the circular rod is rotated. At this time, due to the lateral limit of the adjusting slot, the rotation of the circular rod will drive the outer cylinder to rotate around the soil sampling cylinder. Since the electric telescopic rod is pressed against the soil sampling cylinder, the outer cylinder will be contaminated by the soil sampling mechanism. While the cylinder rotates on its own, it is driven by an electric telescopic rod to continue its downward insertion. This allows the frustum-shaped end of the outer cylinder to cut through the surrounding soil, making it easier to insert the sampling cylinder and ensuring its smooth insertion into the soil. Simultaneously, when the sampling cylinder is inserted into the groundwater layer, the circular rod can be pressed down, causing the L-shaped water sampling pipe to press against the arc-shaped baffle and extend out of the outer cylinder, with the L-shaped water sampling pipe reaching the groundwater surface. At this point, since there is still soil adhering to the L-shaped water sampling pipe and the outer cylinder, further rotation of the circular rod will cause the soil at the lower end of the outer cylinder to fall off and the soil at the end of the L-shaped water sampling pipe to be washed away. After a period of time, the L-shaped water sampling pipe can be lowered again to allow water to enter the inlet for water sampling, avoiding soil contamination and thus ensuring the accuracy of water sampling and testing.

[0025] (3) This invention can greatly avoid the compression of the sampled soil during soil sampling, and can also quickly recover the soil in its original state, thereby reducing the interference with the subsequent soil moisture content and improving the accuracy of soil detection. Specifically, when the soil sampling tube is inserted to sample the soil, the cylindrical structure of the soil sampling tube and the vertical downward pressure can prevent the soil inside the soil sampling tube from being compressed as much as possible. Moreover, the outer tube rotates to cut the soil to ensure smooth insertion, with little impact on the inside of the soil sampling tube. At the same time, when recovering the soil, after the soil sampling tube returns to the ground, it is only necessary to rotate and open the top cover, and then pull the soil sampling tube out in the direction of the insertion knife, so that the two ring blocks can be opened quickly. At this time, the soil is still in its original state and has not been squeezed. Therefore, the soil can be quickly recovered in its original state, thereby reducing the interference with the subsequent soil moisture content and improving the accuracy of soil detection.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0040] Example

[0041] like Figures 1-10 As shown, a sampling and monitoring device based on the ecological spatial response relationship of coal and water includes a limiting frame 100, which includes a top plate 110 and four supporting feet 120 fixed around the top plate 110. A winding device 300 is fixedly installed on the top of the top plate 110. The winding device 300 includes a pair of support plates 310 fixed on the top of the top plate 110. A winding drum 323 is rotatably connected to the support plates 310. A steel wire rope 324 is fixedly wound on the winding drum 323. A wire hole 111 is opened through the middle of the top plate 110. One end of the steel wire rope 324 passes through the wire hole 111 and is fixedly connected to the soil sampling cylinder 600.

[0042] The soil sampling cylinder 600 is rotatably connected to an outer cylinder 200. The support foot 120 has two threaded holes 130 on its upper and lower sides, and a positioning screw 800 is screwed into the threaded hole 130. The top plate 110 has symmetrical through holes 112 on both sides of the wire hole 111. An electric telescopic rod 400 is fixedly installed on the top plate 110. The telescopic end of the electric telescopic rod 400 passes through the through hole 112 and abuts against the top of the soil sampling cylinder 600.

[0043] This invention, through the structural design of the winding drum 323 and the soil sampling tube 600, and the cooperation of the electric telescopic rod 400 and the positioning screw 800, can ensure that the soil sampling tube 600 is always in a vertical state in complex terrain, thereby improving the accuracy of subsequent soil sampling and monitoring. Specifically, when a location is determined to be sampled for soil, the support foot 120 is first installed and fixed on the ground of the area to be tested. At this time, the terrain does not need to be complex; it is sufficient to ensure that the support foot 120 is fixed on the ground. Then, after the outer tube 200 is kept vertical by gravity, the positioning screw 800 is adjusted to limit the outer tube 200. At this time, regardless of whether the limiting frame 100 is vertical or not, the soil sampling tube 600 is always in a vertical state. Under the joint limitation of the positioning screw 800 on the upper and lower threaded holes 130, the extension and pressure of the electric telescopic rod 400 ensures that the soil sampling tube 600 can always be vertically inserted into the soil, thereby improving the accuracy of subsequent soil sampling.

[0044] It should be noted that the accompanying drawings in this application specification are only schematic diagrams and can be adjusted according to the actual situation. No further limitations are made on the specific structural dimensions, and they will not be described in detail here.

[0045] Furthermore, the soil sampling cylinder 600 is formed by splicing two annular blocks 610 to form a cylindrical structure. The upper ends of the two annular blocks 610 together form a threaded opening 611, and a top cover 620 is screwed onto the threaded opening 611. A limiting plate 621 is fixedly provided on the top of the top cover 620, and an air hole 622 communicating with the top cover 620 passes through the limiting plate 621. One end of the steel wire rope 324 is fixedly connected to the middle of the limiting plate 621. A cutting tool 630 is fixedly provided at the lower end of the annular block 610, and an outer ring block 631 is fixedly provided around the upper periphery of the cutting tool 630. The structural design of the top cover 620 and the annular blocks 610 facilitates the subsequent recovery of soil samples, which will be described in detail later.

[0046] It is worth noting that when the soil sampling tube 600 is inserted into the soil and then removed during the soil sampling process, the soil inside the soil sampling tube 600 will not fall out due to the specified removal speed and the internal force of the soil sampling tube 600, thus completing the soil sampling operation. This will not be described in detail here.

[0047] Furthermore, the upper end of the outer cylinder 200 is provided with a limiting port 220, and the limiting disc 621 is positioned and abuts against the upper part of the limiting port 220; the lower end of the outer cylinder 200 is fixedly provided with a frustum-shaped end cylinder 230, and the lower end of the frustum-shaped end cylinder 230 is positioned and abuts against the outer ring block 631; a plurality of blades 231 are evenly provided on the outer surface of the frustum-shaped end cylinder 230. The blades 630 and the blades facilitate the quick insertion of the soil-collecting cylinder 600 into the soil.

[0048] Furthermore, the frustum-shaped end cylinder 230 has symmetrically arranged switching slots 240 on both sides. An arc-shaped baffle 700 is rotatably connected to the switching slot 240. A rotating shaft 710 is fixedly provided at both ends of the arc-shaped baffle 700. The rotating shaft 710 is rotatably connected to the bottom of both ends of the switching slot 240. A torsion spring 720 is sleeved on the rotating shaft 710. The two ends of the torsion spring 720 are fixedly connected to the arc-shaped baffle 700 and the switching slot 240, respectively. A plurality of second blades 730 are evenly provided on the outer surface of the arc-shaped baffle 700.

[0049] It is worth noting that when the soil sampling tube 600 is inserted into the soil, the external soil will not enter the interior of the outer tube 200 due to the obstruction of the arc-shaped baffle 700; and, under the action of the torsion spring 720, the arc-shaped baffle 700 in the normal state will block the switching slot 240, which will be described in detail later.

[0050] Furthermore, a water intake mechanism 500 is provided between the soil sampling cylinder 600 and the outer cylinder 200; the water intake mechanism 500 includes a circular rod 530, and an L-shaped water intake pipe 510 is symmetrically fixedly connected to the inner side of the circular rod 530. An end cap 520 is screwed to the end of the L-shaped water intake pipe 510, and a water level alarm is installed at the center of the surface of the end cap 520; a water inlet 511 is opened on the side wall of the L-shaped water intake pipe 510.

[0051] This invention, through the cooperation of the soil sampling cylinder 600 and the outer cylinder 200, under the control of the water sampling mechanism 500, can ensure that the soil sampling cylinder 600 can be smoothly inserted into the soil, and can also ensure that the water sampling mechanism 500 is not contaminated by the soil during the insertion process, thereby interfering with the accuracy of subsequent water sampling detection. This will be described in detail later.

[0052] It is worth noting that the electric telescopic pole 400 and the water level alarm and other electrical equipment of this invention are all powered by an external power source, which is a conventional setting. The water level alarm will perform alarm notification and other operations when it encounters water, thereby understanding the water level based on the depth of the pressure. This is existing technology and will not be described in detail here.

[0053] Furthermore, the outer cylinder 200 has symmetrical vertically opening adjustment slots 210 on its side wall, and the horizontal pipe body of the L-shaped water intake pipe 510 is slidably connected to the corresponding adjustment slots 210.

[0054] When the soil sampling cylinder 600 needs to be inserted for soil sampling, the limiting position of the rotating rod 320 is released, and then the electric telescopic rod 400 is activated. The electric telescopic rod 400 presses against the soil sampling cylinder 600, causing the soil sampling cylinder 600 to descend and insert into the soil. During this process, the water sampling mechanism 500 is inside the outer cylinder 200, and the external soil will not contaminate the water sampling mechanism 500. When insertion encounters difficulties, the circular rod 530 is rotated. Due to the lateral limiting position of the adjusting slot 210, the rotation of the circular rod 530 will cause the outer cylinder 200 to rotate around the soil sampling cylinder 600. Since the electric telescopic rod 400 is pressing against the soil sampling cylinder 600, the outer cylinder 200 can rotate on its own while being driven by the electric telescopic rod 400 to continue downward insertion, thus allowing the frustum-shaped end cylinder 230 of the outer cylinder 200 to... The surrounding soil is cut to facilitate the insertion of the soil sampling tube 600, ensuring its smooth insertion into the soil. Simultaneously, when the soil sampling tube 600 is inserted into the groundwater layer, the circular rod 530 can be pressed down, causing the L-shaped water sampling pipe 510 to press against the arc-shaped baffle 700 and extend out of the outer cylinder 200, with the L-shaped water sampling pipe 510 reaching the groundwater surface. Since the L-shaped water sampling pipe 510 and the outer cylinder 200 still have loose soil adhering to them, rotating the circular rod 530 further removes the loose soil from the lower end of the outer cylinder 200 and washes away the soil at the end of the L-shaped water sampling pipe 510. After a period of time, the L-shaped water sampling pipe 510 is lowered again to allow water to enter the inlet 511 for water sampling, avoiding soil contamination and ensuring the accuracy of water sample testing.

[0055] Furthermore, the adjusting slot 210 is fixedly connected to the limiting slot 260, and the lower end of the limiting slot 260 is provided with a sliding hole. The longitudinal tube of the L-shaped water intake pipe 510 is slidably connected to the sliding hole. A return spring is sleeved on the longitudinal tube of the L-shaped water intake pipe 510, and the return spring is located inside the limiting slot 260.

[0056] It is worth noting that by setting the limiting groove 260, while ensuring the operation of the L-shaped water intake pipe 510, it further prevents external soil from entering the interior of the outer cylinder 200, reducing the possibility of water pollution; at the same time, the reset spring facilitates the reset of the water intake mechanism 500, and if necessary, isolation nets or other structures can be set on the limiting groove 260.

[0057] Furthermore, the support plate 310 has a rotating hole, and a rotating rod 320 is rotatably connected to the rotating hole. The winding drum 323 is installed on the rotating rod 320 between the two support plates 310. A limiting block 322 is fixedly provided on the rotating rod 320, and the limiting block 322 is located on the outside of the two support plates 310. A handle 321 is fixedly provided at one end of the rotating rod 320. A limiting mechanism for restricting the rotation of the rotating rod 320 is installed on the top plate 110.

[0058] It is worth noting that the limiting mechanism only needs to temporarily limit the rotation rod 320, such as a pin structure, and will not be further limited here; at the same time, the handle 321 can be used to manually retrieve the soil sampling cylinder 600, or the soil sampling cylinder 600 can be retrieved by controlling the rotation of the handle 321 through external equipment. This is a conventional choice and will not be described in detail here.

[0059] Furthermore, the positioning screw 800 includes an upper positioning screw 810 and a lower positioning screw 820, with the lower positioning screw 820 located directly below the upper positioning screw 810; the telescopic end of the electric telescopic rod 400 is fixedly provided with a push plate 410. The push plate 410 improves the control stability of the electric telescopic rod 400.

[0060] A method for operating the aforementioned sampling and monitoring equipment based on the spatial response relationship between coal and water ecosystems includes the following steps:

[0061] S1. Install and fix the support foot 120 on the ground of the area to be tested. Then, after the outer cylinder 200 is kept vertical by gravity, adjust the positioning screw 800 to limit the outer cylinder 200, thereby keeping the soil sampling cylinder 600 vertical.

[0062] S2. Release the limit of the rotating rod 320, and then start the electric telescopic rod 400 so that the electric telescopic rod 400 presses against the soil sampling cylinder 600, so that the soil sampling cylinder 600 descends and inserts into the soil. When insertion is difficult, the soil cutting operation is performed by rotating the circular rod 530.

[0063] S3. When the soil sampling tube 600 is inserted into the groundwater layer, the circular rod 530 is pressed down, so that the L-shaped water sampling pipe 510 presses against the arc-shaped baffle 700 and extends out of the outer tube 200. The L-shaped water sampling pipe 510 extends into the groundwater surface and the circular rod 530 continues to rotate. Finally, the water enters the inlet 511 for water sampling.

[0064] S4. Release the circular rod 530, and the L-shaped water intake pipe 510 returns to the inner cylinder 200. Then pull the rotating rod 320 to wind up the wire rope 324. After the soil intake cylinder 600 returns to the ground, press down the circular rod 530 to extend the end cap 520 out of the outer cylinder 200. Then open the end cap 520 to recover the water. Remove the limiting frame 100, then open the top cover 620 and pull the soil intake cylinder 600 out towards the insert knife 630 to recover the soil.

[0065] This invention can greatly avoid soil compression during soil sampling and can quickly recover the soil in its original state, thereby reducing interference with subsequent soil moisture content analysis and improving the accuracy of soil testing. Specifically, when the soil sampling cylinder 600 is inserted for soil sampling, the cylindrical structure and vertical downward pressure of the cylinder 600 minimize the compression of the soil inside. Furthermore, the outer cylinder 200 rotates to cut the soil, ensuring smooth insertion with minimal impact on the interior of the cylinder 600. Simultaneously, during soil recovery, after the soil sampling cylinder 600 returns to the ground, simply rotate and open the top cover 620, then pull the cylinder 600 out towards the insertion blade 630. This allows the two annular blocks 610 to open quickly, while the soil remains in its original state without compression. Therefore, the soil can be quickly recovered in its original state, reducing interference with subsequent soil moisture content analysis and improving the accuracy of soil testing.

[0066] It is worth noting that since the soil sample being tested for moisture content is located at a specific depth, conventional equipment cannot guarantee that the volume of the extracted soil sample will remain in its original state, which will lead to inaccurate moisture content monitoring. At the same time, when using this equipment to sample water or soil, conventional soil layers will be explored at the designated location in advance. Therefore, it is possible to select equipment of a specific size for fixed-point exploration. This is a routine adjustment and will not be described in detail here.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
