Description

Technical Field

[0001] The present invention relates to the technical field of soil sample sampling, and specifically to an integrated device for collecting and processing soil samples with minimal disturbance at the site. Background Art

[0002] With the continuous development and progress of the economic society, the problem of soil sample pollution has become increasingly serious, and it has even seriously affected daily life. Therefore, soil sample remediation is a powerful means to solve the problem of soil sample pollution. Soil sample remediation is a technical measure to restore the normal function of contaminated soil samples. In the soil sample remediation industry, there are more than one hundred existing soil sample remediation technologies, and there are also more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical, and biological.

[0003] Before soil sample remediation, it is necessary to take samples of the soil in advance for testing. Based on understanding the pollution source, pollution method, and pollution history and current situation, comprehensively consider the type of soil sample, parent material of soil formation, terrain, natural vegetation or crops, etc., arrange sampling points, and then decide on the soil sample remediation plan.

[0004] Soil sample sampling refers to collecting soil samples and then using detection tools to detect elements such as selenium, zinc, iodine, calcium, iron, heavy metals, etc. in the soil samples. Therefore, it is necessary to sample and analyze the soil samples, which requires the use of a soil sample sampler.

[0005] In the prior art, such as a Chinese patent with the application number 202222667472.5, the authorized announcement number CN218566956U, and the name "A Soil Sample Sampling Device", the above patent discloses a soil sample sampling device, which relates to the technical field of soil sample sampling. It includes a horizontally arranged base, a sampling tube vertically arranged below the base, and a positioning component and a transmission component arranged on the base; the positioning component includes four motors and a first drill bit arranged below the motors, and the motors are respectively installed at the four corners of the bottom surface of the base; the top of the sampling tube is a closed structure, a second drill bit is coaxially arranged below the sampling tube, a screw rod is fixedly arranged above the second drill bit, the screw rod is coaxially arranged with the sampling tube, and the top of the screw rod is located inside the sampling tube; the transmission component is used to drive the sampling tube and the second drill bit to move vertically downward, and is used to drive the sampling tube and the second drill bit to rotate around their own axes.

[0006] For another example, a Chinese patent with an application number of 202322962286.9, an authorization announcement number of CN221464903U, and a name of a collection device for soil sample sampling discloses a collection device for soil sample sampling, including a sampling trolley and a column rod frame. A water tank is fixedly installed at the top of the lifting seat. An air cylinder block is fixedly installed inside the soil sample cylinder. A pressing gasket is fixedly connected to the bottom of the sleeve shaft. A reduction motor is fixedly installed at the top of the column rod frame. A threaded lead screw is rotatably connected inside the column rod frame. A lifting seat is slidably connected to the outside of the column rod frame. A water tank is fixedly installed at the top of the lifting seat. The bottom of the lifting seat is fixedly connected to the soil sample cylinder. A ring pipe is fixedly connected to the outside of the soil sample cylinder. An air cylinder block is fixedly installed inside the soil sample cylinder.

[0007] In the prior art such as the above-mentioned patent, to a certain extent, it can meet the needs of soil sample sampling. In the prior art referring to the above-mentioned patent, during the operation of soil sample sampling, usually the sampling cylinder rotates, and the soil sample is collected inside the collection frame inside the sampling cylinder to achieve the sampling operation of the soil sample. As is well known, due to the soft texture of the soil sample itself, in the above-mentioned patent and the prior art, during the process of taking out the soil sample from the sampling device, the soil sample cannot be supported and protected, and the soil sample is extremely likely to have phenomena such as disordered layers when taken out, and the structural integrity of the soil sample in height cannot be guaranteed. At the same time, since the pollution degrees of soil samples at different depths are different, in order to obtain accurate data on the pollution of soil samples at different depths, only multiple samplings can be carried out. At the same time, due to the increase in the friction force between the soil sample and the inner wall of the collection frame after the soil sample is squeezed during the sampling process, there is a situation where the soil sample cannot be quickly discharged, and there are certain deficiencies.

[0008] Therefore, it is an urgent technical problem to be solved how to passively realize the zoning of soil samples at different depths during the resetting process after the sampling cylinder completes the sampling operation and at the same time facilitate the discharging of the soil samples in each zone one by one.

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figures 1 - 21 , the present invention provides a technical solution: a device for integrated collection and processing of micro-disturbance of a site, including a base 2 and a frame 1 installed on the base 2. Specifically, a through groove is provided on the base 2 to facilitate the sampling operation of the sampling cylinder 4 for the soil sample 26. At the same time, a plurality of moving wheels are provided at the bottom of the frame 1, and the moving wheels are self-locking caster wheels, which can improve the flexibility of the device for integrated collection and processing of micro-disturbance of the site to a certain extent, and the use effect is better.

[0049] On the frame 1, there is a connecting frame 3 for installing the sampling cylinder 4 vertically slidably connected through a butting part, so as to improve the stability of the connecting frame 3 when sliding. Specifically, a limiting part 12 is provided between the sampling cylinder 4 and the connecting frame 3. Specifically, the limiting part 12 includes a limiting ring 121 fixedly connected to the peripheral side of the sampling cylinder 4, and an annular groove 122 is formed on the connecting frame 7, wherein the limiting ring 121 is rotatably connected to the annular groove 122, so as to improve the stability of the sampling cylinder 4 when rotating and meet the needs of soil sample sampling operations. In this embodiment, the surfaces of the limiting ring 121 and the annular groove 122 are smooth, which can reduce the friction when the sampling cylinder 4 rotates. A plurality of sampling teeth are provided on the bottom of the sampling cylinder 4, and a driving unit 10 for driving the sampling cylinder 4 to rotate is provided on the connecting frame 3. Specifically, the driving unit 10 includes a driving motor 101 installed on the connecting frame 3. A driving tube 104 is installed on the sampling cylinder 4, and a second bevel gear 103 is installed on the driving tube 104. A power rod rotatably connected to the connecting frame 3 and coaxially connected to the driving motor 101 is provided on the connecting frame 3, and a first bevel gear 102 is installed on the power rod. The first bevel gear 102 meshes with the second bevel gear 103 to provide power for the rotation of the sampling cylinder 4, further facilitating the sampling of soil samples.

[0050] A power mechanism 5 is installed on the frame 1, and the power mechanism 5 drives the sampling cylinder 4 to slide downward, providing power for the downward sliding of the sampling cylinder 4 to meet the working needs. And the connecting frame 3 is connected to the power mechanism 5 through a connecting component 20, facilitating the vertical sliding of the sampling cylinder 4 through the connecting frame 3. A collection frame 11 is installed inside the sampling cylinder 4 through a fixing frame. Specifically, the shape of the collection frame 11 can be designed according to the working needs.

[0051] A partition part is slidably connected to the side wall of the collection frame 11. Specifically, in this embodiment, the partition part includes a first partition plate 13, a second partition plate 14 and a third partition plate 15. The first partition plate 13, the second partition plate 14 and the third partition plate 15 can divide the soil sample 26 inside the collection frame 11 into three partitions. If the sampling depth is relatively shallow, the first partition plate 13 and the second partition plate 14 can be selected. On the contrary, if the sampling depth is relatively deep, several more partition plates can be added, such as a fourth partition plate, a fifth partition plate, etc. The shapes and sizes of the multiple partition plates are the same. This embodiment is described with the partition part including the first partition plate 13, the second partition plate 14 and the third partition plate 15.

[0052] A driving mechanism 16 is provided between the frame 1 and the sampling cylinder 4 to drive the partition part to slide into the collecting frame 11, providing power for the sliding of the first partition board 13, the second partition board 14, and the third partition board 15 into the collecting frame 11, so as to realize the division of the soil sample 26 inside the collecting frame 11 into three partitions, ensuring the structural integrity of the soil sample in terms of height, and thus improving the accuracy of later soil sample detection. Moreover, a reset mechanism 18 is also provided between the connecting component 20 and the sampling cylinder 4 to drive the partition part to slide out of the collecting frame 11. When using the reset mechanism 18 to drive the partition part to slide out of the collecting frame 11, the partition part will contact the soil sample 26 inside the collecting frame 11 and reverse-extrude the soil sample 26 inside the collecting frame 11, so that the soil sample 26 inside the collecting frame 11 can be discharged smoothly, and the use effect is better.

[0053] Specifically, after the sampling operation is completed, the power mechanism 5 will drive the sampling cylinder 4 to slide upward. The height at which the sampling cylinder 4 slides upward is specifically divided into two working stations:

[0054] The first station: During the process that the driving mechanism 16 drives the sampling cylinder 4 to slide upward through the connecting frame 3, the driving mechanism 16 drives the partition part to slide into the collecting frame 11, so as to divide the soil sample 26 inside the collecting frame 11 into multiple modules. At this moment, there will be no situations such as collapse and disorder of layers between the soil samples 26 of different modules, so that the structure of the soil sample 26 will not be damaged, ensuring the structural integrity of the soil sample 26, and further making the detection of the pollution degree of the soil sample 26 at different heights more accurate.

[0055] The second station: When the abutting part restricts the connecting frame 3 and stops sliding upward during the continuous rotation of the power mechanism 5, the reset mechanism 18 drives the partition board to slide out of the collecting frame 11 and discharges the soil samples 26 inside the multiple modules one by one. During this process, when the abutting part restricts the connecting frame 3, at this moment, as the power mechanism 5 continues to rotate, the sampling cylinder 4 is in a static state. The partition part is driven to slide out of the collecting frame 11 through the cooperation between the connecting component 20 and the reset mechanism 18. During the process that the partition part slides out of the collecting frame 11, the partition part will contact the soil sample 26 inside the collecting frame 11 and reverse-extrude the soil sample 26 inside the collecting frame 11, so that the soil sample 26 inside the collecting frame 11 can be discharged smoothly, thus greatly facilitating the discharging of the soil sample 26 after sampling, and the use effect is better.

[0056] In another embodiment provided by the present invention, an expansion component 21 is provided on the partition portion, that is, the first partition plate 13, the second partition plate 14, and the third partition plate 15 are all provided with the expansion component 21, so as to further facilitate the feeding of the soil sample 26. At the same time, the structures and working principles of multiple groups of expansion components 21 are the same, and only the expansion component 21 on the first partition plate 13 will be described here.

[0057] In this embodiment, the expansion component 21 includes a bearing block 211 installed on the first partition plate 13, and a tapered head 212 is slidably connected to the first partition plate 13. An elastic telescopic rod 213 is connected between the bearing frame and the tapered head 212. A first hinge plate 214 is rotatably connected to the tapered head 212, and a second hinge plate 215 is rotatably connected to the bearing block 211. The first hinge plate 214 and the second hinge plate 215 are hinged. And the elastic force of the elastic telescopic rod 213 drives the first hinge plate 214 and the second hinge plate 215 to be in a horizontal state. For this reason, when the first partition plate 13 slides into the collection frame 11, the tapered head 212 slides into the collection frame 11 against the extrusion of the soil sample 26. When the tapered head 212 slides to the inner wall of the collection frame 11 and abuts against the inner wall of the collection frame 11, when the first partition plate 13 continues to slide at this moment, it will squeeze the tapered head 212. At this moment, the tapered head 212 is stationary and the first partition plate 13 continues to slide, causing the first hinge plate 214 and the second hinge plate 215 to rotate. At this moment, the contact surface between the second hinge plate 215 and the soil sample 26 is further increased. The outer surface of the second hinge plate 215 is relatively rough, which can further increase the friction between the second hinge plate 215 and the soil sample 26. A locking portion 216 is further provided between the first partition plate 13 and the tapered head 212. When the tapered head 212 is stationary and the first partition plate 13 slides, the state of the tapered head 212 will be fixed through the locking portion 216, so that the first hinge plate 214 and the second hinge plate 215 are in an unfolded state to meet the working requirements. For this reason, when the first partition plate 13 slides out of the collection frame 11, through the cooperation between the first partition plate 13 and the second partition plate 14, the soil sample 26 inside the collection frame 11 is extruded, further improving the discharging efficiency of the soil sample 26.

[0058] In this embodiment, the locking portion 216 includes a locking block 2161 slidably connected to the first partition plate 13. A locking groove 2162 is formed in the conical head 212, and a locking spring 2163 is provided between the locking block 2161 and the first partition plate 13. The elastic force of the locking spring 2163 drives the locking block 2161 to be clamped in the locking groove 2162 to limit the conical head 212. At the same time, an unlocking rod 217 is provided on the collection frame 11, and an unlocking groove adapted to the unlocking rod 217 is formed in the locking block 2161. When the first partition plate 13 slides out of the interior of the collection frame 11, the cooperation between the unlocking rod 217 and the unlocking groove drives the locking block 2161 to slide out of the corresponding locking groove 2162, so that the conical head 212 can be unlocked. Under the elastic force of the elastic telescopic rod 213, the first hinge plate 214 and the second hinge plate 215 are driven to be in a horizontal state again. The structure of the conical head 212 can better penetrate the soil sample 26, and the effect is better.

[0059] In the embodiment provided by the present invention, a screening mechanism 22 for screening the soil sample 26 is slidably connected to the base 2. Specifically, the screening mechanism 22 is a prior art and is used for preliminary screening of the soil sample 26, so as to reduce the later screening work. A connecting rack 23 is fixedly connected to the screening mechanism 22, a connecting gear 24 is rotatably connected to the base 2, and an intermittent connecting member 25 is provided between the power mechanism 5 and the connecting gear 24. The intermittent connecting member 25 is provided such that when the sampling cylinder 4 slides downward for soil sample sampling operation, the connecting gear 24 will not be driven to rotate at this moment, and the screening mechanism 22 will not slide either. After the sampling operation is completed, when the driving mechanism 16 drives the sampling cylinder 4 to slide upward through the connecting frame 3, the screening mechanism 22 is driven to be located directly below the sampling cylinder 4 through the cooperation of the connecting gear 24 and the connecting rack 23. At this moment, when the reset mechanism 18 drives the partition portion to slide out of the interior of the collection frame 11, the soil samples 26 in the interiors of multiple modules are successively discharged during the process of being located inside the collection frame 11. An inlet hole 221 is formed in the screening mechanism 22 for feeding the soil sample 26. At this moment, the screening mechanism 22 will successively screen the soil samples 26 entering the interior of the screening mechanism 22, and finally obtain the result. While improving the work efficiency, it can also avoid the mixing of soil samples 26 at different depths, improve the accuracy of data during the later detection of soil samples, and greatly meet the work requirements.

[0060] In the embodiment provided by the present invention, the power mechanism 5 includes a driving screw 52 rotatably connected to the frame 1, and a servo motor 51 is installed on the frame 1, and the servo motor 51 is connected to the driving screw 52 through a reducer. Specifically, there are two driving screws 52, which are rotatably connected to both sides of the frame 1, and the two driving screws 52 are connected by a synchronous transmission, thereby further improving the stability of the sampling tube 4 when it slides vertically.

[0061] In the embodiment provided by the present invention, the connecting frame 3 is fixedly connected to the connecting frame 7 on both sides, the abutting portion includes a limit abutting block 8 fixedly connected to the connecting frame 7, and a limit groove 9 adapted to the limit abutting block 8 is provided on the side wall of the frame 1. The connecting component 20 includes a connecting block 201, and the connecting block 201 is slidably connected to the connecting frame 7 through a positioning groove 203, and a connecting spring 202 is provided between the connecting block 201 and the connecting frame 7. Specifically, the elastic coefficient of the connecting spring 202 is large enough to pull the sampling tube 4 to slide upward. And the connecting block 201 is threadedly connected to the driving screw 52. Specifically, a through hole is provided on the connecting frame 7, and the diameter of the through hole is larger than the diameter of the driving screw 52, ​​so that the driving screw 52 does not contact the connecting frame 7. When the sampling tube 4 needs to be reset upward after the sampling operation is completed, the driving screw 52 rotates to drive the connecting block 201 to slide upward, and the sampling tube 4 is driven to slide upward through the connection frame 3 through the cooperation between the connecting spring 202 and the like, and the limiting abutment block 8 at this moment slides vertically inside the limiting groove 9. When the limiting abutment block 8 slides to the top of the limiting groove 9, the driving screw 52 continues to rotate, which drives the connecting block 201 to overcome the elastic force of the connecting spring 202 and slide upward, facilitating subsequent operations.

[0062] In the embodiments provided by the present invention, the driving mechanism 16 includes a threaded rod threadedly connected to the partition portion. Specifically, the threaded rod is rotatably connected to the sampling cylinder 4. At the same time, in this embodiment, the partition portion includes a first partition plate 13, a second partition plate 14, and a third partition plate 15. Therefore, there are three threaded rods, which are respectively threadedly connected to the first partition plate 13, the second partition plate 14, and the third partition plate 15. A gear unit is installed on the threaded rod. Specifically, the gear unit includes a first driving gear 163, a second driving gear 164, and a third driving gear 165, which are respectively installed on the corresponding threaded rods. And a driving plate 162 is vertically slidably connected inside the sampling cylinder 4. An engaging section 166 adapted to the gear unit is provided on the driving plate 162. Specifically, there are three engaging sections 166, which are respectively engaged with the first driving gear 163, the second driving gear 164, and the third driving gear 165. And a trigger rod 161 is fixedly connected to the driving plate 162, and a trigger plate 6 is fixedly connected to the frame 1. The trigger rod 161 is intermittently abutted against the trigger plate 6. Specifically, the trigger rod 161 is slidably connected to the driving tube 104 to meet the working requirements. Therefore, during the use process, when the power mechanism 5 is used to drive the sampling cylinder 4 to slide upward by a certain distance, at this moment, after the trigger rod 161 abuts against the trigger plate 6, as the sampling cylinder 4 continues to slide upward, the trigger plate 6 generates a downward sliding force on the trigger rod 161, thereby being able to drive the trigger rod 161 to drive the driving plate 162 to slide downward. At this moment, since the engaging section 166 is engaged with the first driving gear 163, the second driving gear 164, and the third driving gear 165, it will drive the three threaded rods to rotate together, causing the first partition plate 13, the second partition plate 14, and the third partition plate 15 to slide into the collection box 11, so as to divide the soil sample 26 inside the collection box 11 into multiple modules. At this moment, the soil samples 26 will not collapse or become disordered, so that the structure of the soil sample 26 will not be damaged, and the integrity of the structure of the soil sample 26 can be ensured, thereby making the detection of the pollution degree of the soil sample at different heights more accurate.

[0063] In the embodiment provided by the present invention, the reset mechanism 18 includes a reset plate 181 vertically slidably connected to the inside of the sampling tube 4, and a meshing unit intermittently meshing with the gear unit is provided on the reset plate 181. Specifically, the meshing unit includes a first meshing portion 182, a second meshing portion 183 and a third meshing portion 184. The reset plate 181 is connected to the driving plate 162 through a transmission link 17. When the driving plate 162 drives the partition to slide into the inside of the collection frame 11, the reset plate 181 is driven to slide upward through the linkage 17. The first meshing portion 182 is intermittently meshed with the third driving gear 165, the second meshing portion 183 is intermittently meshed with the second driving gear 164, and the third meshing portion 184 is intermittently meshed with the first driving gear 163. In the original state, the reset plate 181 is located inside the sampling tube 4, so it will not affect the rotation of the sampling tube 4 to perform soil sample sampling. When the sampling operation is completed, the trigger rod 161 is in contact with the trigger plate 6. As the sampling tube 4 continues to slide upward, the trigger plate 6 generates a downward sliding force on the trigger rod 161, which can drive the trigger rod 161 to drive the driving plate 162 to slide downward. At this time, since the meshing section 166 is meshed with the first driving gear 163, the second driving gear 164 and the third driving gear 165, it will drive the three threaded rods to rotate together, so that the first partition plate 13, the second partition plate 14 and the third partition plate 15 slide into the collection frame 11. When the driving plate 162 slides downward, the reset plate 181 is driven to slide upward through the linkage 17. When the driving plate 162 slides downward to a certain position, the meshing section 166 and the gear unit drive the partition to slide to a predetermined position inside the collection frame 11, and the meshing section 166 on the driving plate 162 is separated from the gear unit. During the separation stroke of the meshing section 166 on the driving plate 162 and the gear unit, the reset plate 181 is driven to slide upwards through the linkage 17, and at this moment, the first meshing portion 182 is meshed with the third driving gear 165. A pressure portion 19 is provided between the frame 1 and the reset plate 181. During the continuous rotation stroke of the power mechanism 5, when the abutment portion restricts the connecting frame 3 and stops sliding upwards, the reset plate 181 is driven to slide upwards through the pressure portion 19. When the reset plate 181 slides upwards, the third partition plate 15 is driven to start sliding out of the collection frame 11 through the cooperation between the first meshing portion 182 and the third gear, so that the soil sample 26 under the third partition plate 15 is discharged. When the third partition plate 15 slides to the side away from the collection frame 11, the second meshing portion 183 is not meshed with the second driving gear 164, and the third meshing portion 184 is not meshed with the first driving gear 163. Until, when the reset plate 181 slides upward to a predetermined position, the second meshing portion 183 at this moment meshes with the second driving gear 164, and when the second partition plate 14 slides out from the inside of the collection frame 11, the third meshing portion 184 meshes with the first driving gear 163, causing the first partition plate 13 to slide out from the inside of the collection frame 11.

[0064] In the embodiment provided by the present invention, the pressing part 19 includes a pressing rack 193 slidably connected to the frame 1. The pressing rack 193 is fixedly connected to a pressing rod 191 through a pressing plate 192. A driving frame 185 is fixedly connected to the reset plate 181. The pressing rod 191 is intermittently in contact with the driving frame 185. A triggering unit is arranged between the connecting block 201 and the pressing rack 193. When the connecting block 201 continuously slides upward, the pressing rod 191 is driven by the triggering unit to drive the driving frame 185 to slide upward. In this embodiment, the triggering unit includes a connecting rod 196 rotatably connected to the frame 1. A first pressing gear 194 is installed on the connecting rod 196. The first pressing gear 194 meshes with the pressing rack 193. A second pressing gear 195 is also installed on the connecting rod 196. A power rack 198 is fixedly connected to the connecting block 201. The power rack 198 is intermittently meshed with the second pressing gear 195. When the power mechanism 5 drives the connecting block 201 to continuously slide upward, the power rack 198 at this moment drives the second pressing gear 195 to rotate, drives the pressing rack 193 to slide through the rotating rod 251 and the first pressing gear 194, and then can drive the pressing rod 191 to slide horizontally on the frame 1. A wedge-shaped groove is formed in the driving frame 185. After the pressing rod 191 abuts against the wedge-shaped groove and the pressing rod 191 continuously slides, the reset plate 181 will be driven by the driving frame 185 to slide upward to meet the working requirements. A reset spring 197 is arranged between the pressing rack 193 and the frame 1. The elastic force of the reset spring 197 drives the pressing rod 191 away from the driving frame 185. Therefore, when there is no external force driving the pressing rod 191 to slide, the elastic force of the reset spring 197 drives the pressing rod 191 to slide in the reverse direction to avoid affecting the sampling operation of the sampling cylinder 4.

[0065] In the embodiment provided by the present invention, the linkage member 17 includes a linkage gear 171 rotatably connected inside the sampling cylinder 4. A first linkage part 172 is formed on the driving plate 162. A second linkage part 173 is arranged on the reset plate 181. The first linkage part 172 and the second linkage part 173 are respectively meshed on both sides of the linkage gear 171. A positioning part 174 is arranged on the reset plate 181. The positioning part 174 drives the reset plate 181 to maintain a state inside the sampling cylinder 4 without external force. When the driving plate 162 slides downward, through the cooperation among the first linkage part 172, the linkage gear 171, and the second linkage part 173, etc., the reset plate 181 is driven to slide upward. When the reset plate 181 slides upward a certain distance, the driving frame 185 is driven by the pressing part 19 to drive the reset plate 181 to continue sliding upward to meet the working requirements.

[0066] In the embodiments provided by the present invention, the intermittent connecting member 25 includes a rotating rod 251 installed at the bottom of the driving lead screw 52. A plurality of groups of ratchet teeth 253 are installed on the rotating rod 251 through a base 252. A tooth groove 254 adapted to the ratchet teeth 253 is formed on the connecting gear 24, and the ratchet teeth 253 are clamped in the tooth groove 254. Specifically, a torque spring and a blocking portion are provided between the ratchet teeth 253 and the base 252, so that the ratchet teeth 253 can only rotate counterclockwise and cannot rotate clockwise in the original state. In this embodiment, when the driving lead screw 52 rotates forward, the ratchet teeth 253 are driven to rotate clockwise through the rotating rod 251. At this time, the arc surface on the back of the ratchet teeth 253 abuts against the wedge surface of the tooth groove 254, and the ratchet teeth 253 are passively driven to rotate counterclockwise, so the connecting gear 24 cannot be driven to rotate. On the contrary, when the driving lead screw 52 rotates reversely, the ratchet teeth 253 are driven to rotate counterclockwise through the rotating rod 251. At this time, the end of the ratchet teeth 253 is clamped inside the tooth groove 254, and then the connecting gear 24 can be driven to rotate. Through the cooperation of the connecting gear 24 and the connecting rack 23, the screening mechanism 22 is driven to slide below the sampling cylinder 4, facilitating the subsequent screening operation of the soil sample 26 and greatly improving the working efficiency of the device.
