[0002] Soil sampling refers to the process of collecting soil samples from a specific location. These samples are then sent to the laboratory for various analyses to evaluate the physical, chemical and biological properties of the soil. Soil sampling is an important step in environmental monitoring, agricultural production, land management and scientific research. Its purpose is to understand the quality of the soil, identify potential problems (such as pollution), and provide a scientific basis for decision-making.

[0003] The patent publication number is CN118392561A, which states in its specification that “the present application relates to a soil detection sampling device and a soil sampling method, the soil detection sampling device comprises a base, a cylinder fixed to the lower end of the base, a collecting box rotatably connected to the outer peripheral wall of the cylinder, a spiral shaft coaxially arranged in the cylinder and rotatably connected to the base along the circumferential direction, a rotary drive source arranged at the upper end of the base and used to drive the spiral shaft to rotate, a cone cover arranged at the lower end of the cylinder, and a collecting box rotatably connected to the outer peripheral wall of the cylinder. A connecting rod connected to the spiral shaft and connected to the cone cover at the lower end, a linear drive source provided on the base and connected to the connecting rod, and a digging rod pivotally connected to the lower end of the spiral shaft, a discharge port is provided on the peripheral wall of the cylinder close to the base, and a collection box has a collection port corresponding to the discharge port; the digging rod includes a driving part, a pivoting part and a digging part, which are connected in sequence, the pivoting part is pivotally connected to the lower end of the casing, the driving part extends into the casing, and the digging part is located outside the casing; the present application has the effect of preventing the upper and lower layers of soil from mixing.

[0004] However, the existing technology has the following disadvantages during use: in actual use, although the above technology is designed with a retractable digging rod and a segmented conveying structure to reduce the mixing of soil at different depths, the spiral shaft easily drives and adheres the soil along the inner wall of the cylinder during rotation, especially under high humidity or sticky soil conditions. The residue cannot be discharged in time and is easily mixed with the newly sampled soil during the next stage of sampling, resulting in unclear stratification. During the drilling or lifting process, the soil encounters high humidity or loose texture, and is prone to collapse or slippage, causing the upper soil sample to seep into the lower layer, affecting the representativeness of the sample and the accuracy of the analysis results. Therefore, a soil detection sampling device and sampling method are urgently needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that, during actual use, although the above technology designs a retractable digging rod and a segmented conveying structure to reduce the mixing of soil at different depths, the spiral shaft easily drives and adheres the soil along the inner wall of the cylinder during rotation, especially under high humidity or sticky soil conditions, the residue cannot be discharged in time, and it is very easy to mix with the newly sampled soil during the next stage of sampling, resulting in unclear stratification. During the drilling or lifting process, the soil encounters high humidity or loose texture, and is prone to collapse or sliding, causing the upper soil sample to seep into the lower layer, affecting the representativeness of the sample and the accuracy of the analysis results.

At this time, the installation barrel, magnet two and the movable block are aligned, and the movable block is no longer restricted by the limit shaft.

[0019] Preferably, a limiting pin is provided on the outer surface of the limiting frame, and the outer surface of the limiting pin is in sliding contact with the outer surface of the limiting shaft. A group of the inner walls of the mounting barrels are provided with a plurality of lifting boxes, and the inner walls of the plurality of lifting boxes are provided with a film. The outer surface of the transverse frame is provided with motor three, and the motor three is electrically connected to the power supply box.

[0020] The technical effect of adopting the above further solution is: the film is set on the top of the lifting box to prevent external debris from entering the interior of the lifting box, and the motor three is fixed on the outer surface of the transverse frame to enhance the stability of the motor three.

[0021] Preferably, the inner wall of the transverse frame is provided with multiple worm gears 1, the outer surfaces of the multiple worm gears 1 are provided with two transmission shafts, the outer surface of one of the worm gears 1 is provided at the output end of the motor 3, the outer surfaces of the multiple worm gears 1 are provided with worm wheels 1, the inner walls of the multiple worm wheels 1 are provided with rotating shafts, and the outer surfaces of the multiple rotating shafts are respectively provided on the inner walls of multiple mounting barrels.

[0022] The technical effect of adopting the above-mentioned further scheme is: after one group of installation barrels completely enters the interior of the sampling tube, the control motor three drives the worm one, the transmission shaft and the worm gear one to rotate when it works, and when the worm gear one rotates, it drives the rotating shaft, the worm two and the worm gear two to rotate.

[0024] The technical effect of adopting the above further solution is: when the worm gear 2 rotates, it drives the threaded rod 1 to rotate in the fixed plate, and when the threaded rod 1 rotates, it drives the push frame to move vertically in the fixed plate.

[0026] The technical effect of adopting the above-mentioned further scheme is: when the pushing frame moves, it drives the magnet 1, the lifting box and the film into the soil inside the sampling tube. After the film is separated from the inner wall of the lifting box during the soil squeezing, it is squeezed to the bottom of the lifting box, and the soil is embedded in the lifting box during this process.

[0027] The present invention also provides a sampling method of a soil detection sampling device, which is used as follows:

[0028] In step 1, the staff holds the horizontal bar at the top of the mobile frame and uses the universal wheels to move the mobile frame to the sampling area. The staff controls the multiple electric push rods 1 through the control panel to drive the multiple tapered rods to insert into the ground. When the control motor 1 is working, it drives the sampling barrel to rotate. When the sampling barrel rotates, it drives the threaded groove and the crushing blade to rotate. When the control motor 2 is working, it drives the threaded rod 2 to rotate forward. When the threaded rod 2 rotates, it drives the lifting plate to move toward the ground on the limit column. When the lifting plate moves, it drives the motor 1 and the sampling barrel to move toward the ground. After the outer surface of the lifting plate contacts the outer surface of the mounting frame, the control motor 1 stops working, and at the same time, the control motor 2 drives the threaded rod 2 to rotate in the opposite direction to drive the sampling barrel to return to its original position.

[0029] In step 2, the staff manually rotates the limit shaft on the sampling tube to the same axis as the limit pin, moves the limit pin on the limit frame to the limit shaft, so that the limit pin restricts the limit shaft, and then pulls the limit shaft out from the sampling tube so that the limit shaft passes through the lifting plate. The limit shaft stops after being pulled out of the sampling tube for four-fifths, and controls the electric push rod 2 to drive the movable plate, the transverse frame and the installation barrel to move horizontally. The installation barrel pushes the movable block and the soil in the sampling tube when moving;

[0030] Step three, after one group of installation barrels completely enters the sampling barrel, the control motor three drives the worm one, the transmission shaft and the worm gear one to rotate. When the worm gear one rotates, it drives the rotating shaft, the worm two and the worm gear two to rotate. When the worm gear two rotates, it drives the threaded rod one to rotate in the fixed plate. When the threaded rod one rotates, it drives the pushing frame to move vertically in the fixed plate. When the pushing frame moves, it drives the magnet one, the lifting box and the film into the soil inside the sampling barrel. After the film is separated from the inner wall of the lifting box during soil extrusion, it is squeezed to the bottom of the lifting box. The soil is embedded in the lifting box in this process. Then the motor three works in the opposite direction to drive the pushing frame and the lifting box to return to their original position. The output end of the electric push rod two is controlled to contract to drive the installation barrel to be pulled out of the sampling barrel and the movable block is restored to its original position. The motor three is then controlled to push the lifting box to extend out of the installation barrel. The staff takes away the lifting box and puts in a new lifting box.

[0031] Compared with the prior art, the advantages and positive effects of the present invention are:

[0032] When the present invention is in use, the threaded rod rotates to drive the pushing frame to move vertically in the fixed plate. When the pushing frame moves, it drives the magnet 1, the lifting box and the film to enter the soil inside the sampling tube. After the film is separated from the inner wall of the lifting box during soil squeezing, it is squeezed to the bottom of the lifting box. The soil is embedded in the lifting box during this process. By sampling soil at different heights inside the sampling tube, it is beneficial to improve the stability of the sampling process, the representativeness of the soil sample and the accuracy of the analysis results.

[0033] When the present invention is in use, the sampling tube rotates, driving the thread groove and the crushing blade to rotate, which is convenient for crushing hard objects in the soil. The thread groove gradually penetrates into the soil like a screw, reducing the required vertical pressure, effectively reducing the direct friction between the soil and the sampling tube, and at the same time reducing the damage to the soil inside the sampling tube when the sampling tube penetrates into the soil, improving the integrity of the soil inside the sampling tube, and helping to avoid unclear soil stratification and collapse or sliding, which may cause the upper soil to seep into the lower layer.

[0034] When the present invention is in use, after one group of installation barrels completely enters the interior of the sampling cylinder, the lifting box is located in the middle area of ​​the sampling cylinder, so that the soil sample obtained by the lifting box is the soil in the middle area of ​​the sampling cylinder, which is beneficial to avoid obtaining the soil at the inner wall of the sampling cylinder, further reducing the unclear stratification of the upper soil and the lower soil, and at the same time utilizing the friction between the inner wall of the sampling cylinder and the soil to facilitate reducing the collapse of the soil inside the sampling cylinder.

[0053] In one embodiment, when in use, the power supply box 10 provides power to the electric push rod 1 202, the electric push rod 2 205, the motor 1 103, the motor 2 7, the control panel 8 and the motor 3 211. At the same time, the control panel 8 controls the electric push rod 1 202, the electric push rod 2 205, the motor 1 103, the motor 2 7 and the motor 3 211. The staff holds the cross bar at the top of the mobile rack 2 and uses the universal wheel 201 to move the mobile rack 2 to the area to be sampled. The staff controls the multiple electric push rods 1 202 to move through the control panel 8. The operation drives multiple tapered rods 203 to be inserted into the ground, which is convenient for fixing the mobile frame 2 and improving the stability of subsequent soil sampling work. When the threaded rod 25 rotates, it drives the lifting plate 4 to move toward the ground on the limit column 3. When the lifting plate 4 moves, it drives the motor 103 and the sampling tube 1 to move toward the ground, so that the sampling tube 1 rotates deep into the ground. After the outer surface of the lifting plate 4 contacts the outer surface of the mounting frame 204, the motor 103 is controlled to stop working, and at the same time, the motor 27 is controlled to drive the threaded rod 25 to rotate in the opposite direction to drive the sampling tube 1 to return to its original position.

[0054] Example 3, as Figure 1-8 As shown, a limit pin 6 is provided on the outer surface of the limit frame 106, and the outer surface of the limit pin 6 is in sliding contact with the outer surface of the limit shaft 104. A plurality of lifting boxes 209 are provided on the inner wall of one group of mounting barrels 208, and a film 210 is provided on the inner wall of the plurality of lifting boxes 209. The outer surface of the transverse frame 207 is provided with a motor three 211, and the motor three 211 is electrically connected to the power supply box 10.

The other ends of the multiple rotating shafts 215 are each provided with a worm 216, the outer surfaces of the multiple worm 216 are respectively arranged on the inner walls of the multiple mounting barrels 208, the outer surfaces of the multiple worm 216 are each provided with a worm wheel 217, the inner walls of the multiple worm wheels 217 are each provided with a threaded rod 1 218, the other ends of the multiple threaded rod 1 218 are each provided with a fixing plate 220, the outer surfaces of the multiple fixing plates 220 are respectively arranged on the inner walls of the multiple mounting barrels 208, the inner walls of the multiple fixing plates 220 are each provided with a pushing frame 219, the inner walls of the multiple pushing frames 219 are respectively arranged on the outer surfaces of the multiple threaded rod 1 218, the outer surfaces of the multiple pushing frames 219 are each provided with a magnet 1 221, the outer surfaces of the multiple magnet 1 221 are each provided with an iron sheet 222, and the outer surfaces of the multiple iron sheets 222 are respectively arranged on the inner walls of the multiple lifting boxes 209.

[0055] In one embodiment, when in use, the output end of the motor 103 can rotate after the power is cut off. The staff manually rotates the limit shaft 104 on the sampling tube 1 to the same axis as the limit pin 6, and moves the limit pin 6 on the limit frame 106 to the limit shaft 104, so that the limit pin 6 limits the limit shaft 104, and then pulls the limit shaft 104 out of the sampling tube 1 so that the limit shaft 104 passes through the lifting plate 4. The limit shaft 104 stops after being pulled out of the sampling tube 1 by four-fifths. At this time, the installation barrel 208, the magnet 2 9 and the movable block 105 are aligned. When the movable block 105 is aligned, it is no longer restricted by the limit shaft 104. The electric push rod 205 is controlled to drive the movable plate 206, the transverse frame 207 and the installation barrel 208 to move horizontally. When the installation barrel 208 moves, it pushes the movable block 105 and the soil in the sampling tube 1. Under the adsorption of the magnet 29, the movable block 105 will not fall. After one set of the installation barrels 208 completely enters the interior of the sampling tube 1, the control motor 3 211 drives the worm 1 213, the transmission shaft 212 and the worm gear 1 214 to rotate. When the worm gear 1 214 rotates, it drives the rotating shaft 215 and the worm The second 216 and the worm gear second 217 rotate, and when the worm gear second 217 rotates, the threaded rod one 218 is driven to rotate in the fixed plate 220, and when the threaded rod one 218 rotates, the pushing frame 219 is driven to move vertically in the fixed plate 220, and when the pushing frame 219 moves, it drives the magnet one 221 and the lifting box 209 and the film 210 to enter the soil inside the sampling tube 1. After the film 210 is separated from the inner wall of the lifting box 209 during the soil extrusion, it is squeezed to the bottom of the lifting box 209. The soil is embedded in the lifting box 209 in this process, and then the motor three 211 is reversed. The working direction drives the pushing frame 219 and the lifting box 209 to return to their original positions. During the vertical movement of the lifting box 209, the adsorption force of the magnet 1 221 on the iron sheet 222 at the bottom of the lifting box 209 is sufficient to offset the friction force of the soil on the lifting box 209, so as to facilitate bringing the lifting box 209 back into the installation barrel 208. The output end of the electric push rod 205 is controlled to contract to drive the installation barrel 208 to be pulled out from the sampling tube 1, and the movable block 105 is restored to its original position. Then the limit shaft 104 is inserted back into the sampling tube 1 to limit the movable block 105 again, and the limit pin 6 is separated from the limit shaft 104.

[0056] The sampling method of a soil detection sampling device according to an embodiment of the present application is as follows:

[0057] In step 1, the staff member holds the horizontal bar at the top of the mobile frame 2 and uses the universal wheel 201 to move the mobile frame 2 to the area to be sampled. The staff member controls the multiple electric push rods 202 to work through the control panel 8 to drive the multiple tapered rods 203 to insert into the ground, and controls the motor 103 to drive the sampling tube 1 to rotate when working. When the sampling tube 1 rotates, it drives the threaded groove 101 and the crushing blade 102 to rotate. When the motor 2 7 is controlled to work, it drives the threaded rod 2 5 to rotate forward. When the threaded rod 2 5 rotates, it drives the lifting plate 4 to move toward the ground on the limit column 3. When the lifting plate 4 moves, it drives the motor 103 and the sampling tube 1 to move toward the ground. After the outer surface of the lifting plate 4 contacts the outer surface of the mounting frame 204, the control motor 103 stops working, and at the same time controls the motor 2 7 to drive the threaded rod 2 5 to rotate in the opposite direction to drive the sampling tube 1 to return to its original position.

[0058] In step 2, the staff manually rotates the limit shaft 104 on the sampling tube 1 to the same axis as the limit pin 6, moves the limit pin 6 on the limit frame 106 to the limit shaft 104, so that the limit pin 6 limits the limit shaft 104, and then pulls the limit shaft 104 out of the sampling tube 1 so that the limit shaft 104 passes through the lifting plate 4. The limit shaft 104 stops after being pulled out of the sampling tube 1 by four-fifths, and controls the electric push rod 205 to drive the movable plate 206, the transverse frame 207 and the installation barrel 208 to move laterally. The installation barrel 208 pushes the movable block 105 and the soil in the sampling tube 1 when moving;

[0059] Step 3: After one set of mounting barrels 208 is completely inserted into the sampling tube 1, the control motor 3 211 drives the worm 1 213, the transmission shaft 212 and the worm gear 1 214 to rotate when the control motor 3 211 is working. When the worm gear 1 214 rotates, it drives the rotating shaft 215, the worm 2 216 and the worm gear 2 217 to rotate. When the worm gear 217 rotates, it drives the threaded rod 1 218 to rotate in the fixed plate 220. When the threaded rod 1 218 rotates, it drives the push frame 219 to move vertically in the fixed plate 220. When the push frame 219 moves, it drives the magnet 1 221, the lifting box 209 and the film 210 to move. The film 210 is squeezed into the soil inside the sampling tube 1, and after being separated from the inner wall of the lifting box 209 during the soil squeezing, it is squeezed to the bottom of the lifting box 209. The soil is embedded in the lifting box 209 in this process. Then the motor three 211 works in reverse to drive the pushing frame 219 and the lifting box 209 to return to their original positions, and the output end of the electric push rod 205 is controlled to shrink to drive the installation barrel 208 to be pulled out of the sampling tube 1, and the movable block 105 is restored to its original position, and then the motor three 211 is controlled to push the lifting box 209 out of the installation barrel 208. The staff takes away the lifting box 209 and puts in a new lifting box 209.

[0060] Working principle: When in use, the power supply box 10 provides power to the electric push rod 1 202, the electric push rod 2 205, the motor 1 103, the motor 2 7, the control panel 8 and the motor 3 211. At the same time, the control panel 8 controls the electric push rod 1 202, the electric push rod 2 205, the motor 1 103, the motor 2 7 and the motor 3 211. The staff holds the cross bar at the top of the mobile frame 2 and uses the universal wheel 201 to move the mobile frame 2 to the area to be sampled. The staff controls the multiple electric push rods 1 202 to work and drive the multiple tapered rods 203 to insert into the ground through the control panel 8, so as to fix the mobile frame 2 and improve the stability of the subsequent soil sampling work. When in use, the initial state of the limit pin 6 is different from the limit axis 104. When the sampling tube 1 is in contact, the control motor 103 drives the sampling tube 1 to rotate. When the sampling tube 1 rotates, it drives the thread groove 101 and the crushing blade 102 to rotate, which is convenient for crushing hard objects in the soil. The thread groove 101 gradually penetrates into the soil like a screw, reducing the required vertical pressure and effectively reducing the direct friction with the soil. When the sampling tube 1 rotates, it drives the limit shaft 104 and the movable block 105 to rotate. When the control motor 27 works, it drives the threaded rod 25 to rotate forward. When the threaded rod 25 rotates, it drives the lifting plate 4 to move toward the ground on the limit column 3. When the lifting plate 4 moves, it drives the motor 103 and the sampling tube 1 to move toward the ground, so that the sampling tube 1 rotates and penetrates into the ground. When the outer surface of the lifting plate 4 is in contact with the mounting bracket 204, the lifting plate 4 is moved. After the outer surface of the control motor 103 contacts, the control motor 103 stops working, and the control motor 2 7 drives the threaded rod 2 5 to rotate in the opposite direction to drive the sampling tube 1 to return to its original position. When in use, the output end of the motor 103 can rotate after the power is cut off. The staff manually rotates the limit shaft 104 on the sampling tube 1 to the same axis as the limit latch 6, and moves the limit latch 6 on the limit frame 106 to the limit shaft 104, so that the limit latch 6 limits the limit shaft 104, and then pulls the limit shaft 104 out of the sampling tube 1 so that the limit shaft 104 passes through the lifting plate 4. The limit shaft 104 is pulled out of the sampling tube 1 by four-fifths and then stops. At this time, the installation barrel 208, the magnet 2 9 and the movable block 105 are aligned, and the movable block 105 is no longer restricted by the limit shaft 104 , control the electric push rod 205 to drive the movable plate 206, the transverse frame 207 and the installation barrel 208 to move horizontally, and the installation barrel 208 pushes the movable block 105 and the soil in the sampling tube 1 when moving. The movable block 105 will not fall under the adsorption of the magnet 29. After one set of installation barrels 208 completely enters the interior of the sampling tube 1, the control motor 3 211 drives the worm 1 213, the transmission shaft 212 and the worm gear 1 214 to rotate when the worm gear 1 214 rotates. When the worm gear 1 214 rotates, it drives the rotating shaft 215, the worm 216 and the worm gear 217 to rotate. When the worm gear 217 rotates, it drives the threaded rod 1 218 to rotate in the fixed plate 220. When the threaded rod 1 218 rotates, it drives the pushing frame 219 to move vertically in the fixed plate 220.When the push frame 219 moves, it drives the magnet 1 221, the lifting box 209 and the film 210 to enter the soil inside the sampling tube 1. After the film 210 is separated from the inner wall of the lifting box 209 during the soil squeezing, it is squeezed to the bottom of the lifting box 209. The soil is embedded in the lifting box 209 during this process. Then the motor 3 211 works in the reverse direction to drive the push frame 219 and the lifting box 209 to return to their original positions. During the vertical movement of the lifting box 209, the adsorption force of the magnet 1 221 on the iron sheet 222 at the bottom of the lifting box 209 is sufficient to offset the friction force of the soil on the lifting box 209, making it easier to bring the lifting box 209 back into the installation barrel 208. The output end of the electric push rod 205 is controlled to retract and drive the installation barrel 208 to be withdrawn from the sampling tube 1, and the movable block 105 is restored to its original position. Then the limit shaft 104 is inserted back into the sampling tube 1 to restrict the movable block 105 again, and the limit latch 6 is separated from the limit shaft 104.
