Description

Technical Field

[0001] The invention relates to the technical field of soil sample sampling, and in particular to a site micro-disturbance collection and processing integrated device. Background Art

[0002] With the continuous development and progress of the economy and society, the problem of soil sample contamination has become more and more serious, and has even seriously affected daily life. Therefore, soil sample remediation is a powerful means to solve the problem of soil sample contamination. 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 100 existing soil sample remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological.

[0003] Before soil sample remediation, soil samples need to be sampled and tested in advance. Based on the understanding of the pollution source, pollution method, pollution history and current status, the sampling points are arranged by comprehensively considering the soil sample type, parent material, topography, natural vegetation or crops, and then a plan for soil sample remediation is decided.

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

[0005] In the prior art, there is a Chinese patent with application number 202222667472.5, authorization announcement number CN218566956U, and name of a soil sample sampling device. The above patent discloses a soil sample sampling device, which relates to the technical field of soil sample sampling, and includes a horizontally arranged base, a sampling tube vertically arranged below the base, and a positioning assembly and a transmission assembly arranged on the base; the positioning assembly includes four motors and a first drill bit arranged below the motor, and the motors are respectively installed at the top 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 is fixedly arranged above the second drill bit, the screw is coaxially arranged with the sampling tube, and the top of the screw is located inside the sampling tube; the transmission assembly 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] Another example is a Chinese patent with application number 202322962286.9, authorization announcement number CN221464903U, and name "A soil sample collection device". The above patent discloses a soil sample collection device, including a sampling cart and a column rack, the top of the lifting seat is fixedly installed with a water tank, the inside of the soil sample tube is fixedly installed with a cylinder block, the bottom of the sleeve shaft is fixedly connected with a press-fit washer, the top of the column rack is fixedly installed with a reduction motor, the inside of the column rack is rotatably connected with a threaded screw, the outside of the column rack is slidably connected with a lifting seat, the top of the lifting seat is fixedly installed with a water tank, the bottom of the lifting seat is fixedly connected with a soil sample tube, the outside of the soil sample tube is fixedly connected with an annular tube, and the inside of the soil sample tube is fixedly installed with a cylinder block.

[0007] The prior art, such as the above-mentioned patent, can meet the needs of soil sample sampling to a certain extent. Referring to the prior art, including the above-mentioned patent, when performing soil sample sampling, a sampling tube is usually rotated to collect the soil sample inside the collection frame inside the sampling tube to realize the soil sample sampling operation. It is known that due to the soft texture of the soil sample itself, in the above-mentioned patent and the prior art, the soil sample cannot be supported and protected during the process of taking the soil sample out of the sampling device. The soil sample is very likely to have a disordered layer when it is taken out, and the structural integrity of the soil sample at height cannot be guaranteed. At the same time, due to the different degrees of contamination of soil samples at different depths, in order to obtain accurate data on the contamination of soil samples at different depths, only multiple samplings can be performed. At the same time, because the soil sample is squeezed during the sampling process, the friction between the soil sample and the inner wall of the collection frame increases, and there is a situation where the soil sample cannot be quickly discharged, which has certain shortcomings.

[0008] It can be seen that how to passively realize the partitioning of soil samples at different depths during the reset stroke of the sampling tube after completing the sampling operation, and how to conveniently discharge the soil samples inside each partition one by one, is a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 21 The present invention provides a technical solution: a site micro-disturbance collection and processing integrated device, comprising a base 2 and a frame 1 mounted on the base 2. Specifically, a through slot is provided on the base 2 to facilitate the sampling operation of the sampling tube 4 for the soil sample 26. At the same time, a plurality of sets of moving wheels are provided on the bottom of the frame 1, wherein the moving wheels are self-locking casters, which can improve the flexibility of the site micro-disturbance collection and processing integrated device to a certain extent, and the use effect is better.

[0049] A connecting frame 3 for mounting a sampling tube 4 is vertically slidably connected to the frame 1 through an abutment portion, thereby improving the stability of the connecting frame 3 when sliding. Specifically, a limiting portion 12 is provided between the sampling tube 4 and the connecting frame 3, and specifically, the limiting portion 12 includes a limiting ring 121 fixedly connected to the peripheral side of the sampling tube 4, and an annular groove 122 is provided on the connecting frame 7, wherein the limiting ring 121 is rotatably connected to the annular groove 122, thereby improving the stability of the sampling tube 4 when rotating, and meeting 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 force when the sampling tube 4 rotates. A plurality of sampling teeth are provided on the bottom of the sampling tube 4, and a driving unit 10 for driving the sampling tube 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, wherein a driving tube 104 is installed on the sampling tube 4, and a second bevel gear 103 is installed on the driving tube 104, and a power rod rotatably connected to the connecting frame 3 and coaxially connected to the driving motor 101, and a first bevel gear 102 is installed on the power rod, wherein the first bevel gear 102 is meshed with the second bevel gear 103, providing power for the rotation of the sampling tube 4, further facilitating the sampling of soil samples.

[0050] The frame 1 is provided with a power mechanism 5, which drives the sampling tube 4 to slide downward, providing power for the downward sliding of the sampling tube 4 to meet the working needs. The connecting frame 3 is connected to the power mechanism 5 through a connecting component 20, so that the sampling tube 4 can slide vertically through the connecting frame 3. A collecting frame 11 is installed inside the sampling tube 4 through a fixing frame. Specifically, the shape of the collecting frame 11 can be designed according to the working needs.

[0051] The side wall of the collection frame 11 is slidably connected with a partition. Specifically, in this embodiment, the partition 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 separate the soil sample 26 inside the collection frame 11 into three partitions. If the sampling depth is shallow, the first partition plate 13 and the second partition plate 14 can be selected. On the contrary, if the sampling depth is deep, more partition plates can be added, such as a fourth partition plate, a fifth partition plate, etc. The shapes and sizes of the multiple groups of partition plates are consistent. In this embodiment, the partition includes the first partition plate 13, the second partition plate 14 and the third partition plate 15 for description.

[0052] A driving mechanism 16 for driving the partition to slide into the collection frame 11 is provided between the frame 1 and the sampling tube 4, and provides power for the first partition plate 13, the second partition plate 14 and the third partition plate 15 to slide into the collection frame 11, so that the soil sample 26 inside the collection frame 11 can be divided into three partitions, ensuring the structural integrity of the soil sample in height, thereby improving the accuracy of the later soil sample detection. A reset mechanism 18 for driving the partition to slide out of the collection frame 11 is also provided between the connecting component 20 and the sampling tube 4. When the reset mechanism 18 is used to drive the partition to slide out of the collection frame 11, the partition will contact the soil sample 26 inside the collection frame 11, and the soil sample 26 inside the collection frame 11 will be reversely squeezed, so that the soil sample 26 inside the collection frame 11 can be smoothly discharged, and the use effect is better.

[0053] Specifically, when the sampling operation is completed, the power mechanism 5 will drive the sampling tube 4 to slide upward. At the height at which the sampling tube 4 slides upward, there are specifically two working positions:

[0054] First station: When the driving mechanism 16 drives the sampling tube 4 to slide upward through the connecting frame 3, the driving mechanism 16 drives the partition to slide into the collecting frame 11, so that the soil sample 26 inside the collecting frame 11 is divided into multiple modules. At this moment, there will be no collapse or disorder between the soil samples 26 in different modules, 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 guaranteed, thereby making the detection of the degree of contamination of the soil sample 26 at different heights more accurate.

[0055] At the second station, when the abutment part restricts the connection frame 3 and stops sliding upward during the continuous rotation of the power mechanism 5, the reset mechanism 18 drives the partition plate to slide out from the inside of the collection frame 11 to discharge the soil samples 26 inside the multiple modules one by one. In this process, after the abutment part restricts the connection frame 3, at this moment, as the power mechanism 5 continues to rotate, the sampling tube 4 is in a static state, and the partition part is driven to slide out from the inside of the collection frame 11 through the cooperation between the connecting part 20 and the reset mechanism 18. During the sliding stroke of the partition part from the inside of the collection frame 11, the partition part will contact the soil sample 26 inside the collection frame 11, and reversely squeeze the soil sample 26 inside the collection frame 11, so that the soil sample 26 inside the collection frame 11 can be discharged smoothly, thereby greatly facilitating the discharge of the sampled soil sample 26, and achieving a better use effect.

[0056] The present invention provides another embodiment, in which an expansion component 21 is provided on the partition, 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 discharge of soil samples 26. At the same time, the structures and working principles of multiple groups of expansion components 21 are consistent, and only the expansion component 21 on the first partition plate 13 is described here.

[0057] In this embodiment, the expansion component 21 includes a bearing block 211 mounted on the first partition plate 13, and a conical head 212 is slidably connected to the first partition plate 13, the bearing frame and the conical head 212 are connected by an elastic telescopic rod 213, a first hinge plate 214 is rotatably connected to the conical head 212, a second hinge plate 215 is rotatably connected to the bearing block 211, and the first hinge plate 214 and the second hinge plate 215 are hinged. 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. Therefore, when the first partition plate 13 slides toward the inside of the collection frame 11, the conical head 212 overcomes the squeezing of the soil sample 26 and slides toward the inside of the collection frame 11. When the conical head 212 slides to the inner wall of the collection frame 11 and contacts the inner wall of the collection frame 11, when the first partition plate 13 continues to slide, the conical head 212 will be squeezed. At this moment, the conical head 212 is stationary while the first partition plate 13 continues to slide, so that the first hinge plate 214 and the second hinge plate 215 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 also provided between the first partition plate 13 and the conical head 212. When the conical head 212 is stationary and the first partition plate 13 slides, the locking portion 216 will fix the state of the conical head 212, so that the first hinge plate 214 and the second hinge plate 215 are in an unfolded state, meeting the working needs. To this end, when the first partition plate 13 slides out from the collecting frame 11 , the soil sample 26 inside the collecting frame 11 is squeezed out through the cooperation between the first partition plate 13 and the second partition plate 14 , further improving the discharge 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, wherein a locking groove 2162 is opened on the conical head 212, and a locking spring 2163 is arranged between the locking block 2161 and the first partition plate 13, and the elastic force of the locking spring 2163 drives the locking block 2161 to be clamped in the locking groove 2162, thereby limiting 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 provided on the locking block 2161. When the first partition plate 13 slides out from the inside of the collection frame 11, the cooperation between the unlocking rod 217 and the unlocking groove drives the locking block 2161 to slide out from the inside of the locking groove 2162, so that the conical head 212 can be unlocked, and the first hinge plate 214 and the second hinge plate 215 are driven to be in a horizontal state again under the elastic force of the elastic telescopic rod 213. The structure of the conical head 212 can better pass through the soil sample 26, and the effect is better.

[0059] In the embodiment provided by the present invention, a screening mechanism 22 for screening soil samples 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 samples 26, thereby reducing the later screening work. The screening mechanism 22 is fixedly connected with a connecting rack 23, the base 2 is rotatably connected with a connecting gear 24, and an intermittent connector 25 is arranged between the power mechanism 5 and the connecting gear 24. The intermittent connector 25 is arranged so that when the sampling tube 4 slides downward to perform the 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, the driving mechanism 16 drives the sampling tube 4 to slide upward through the connecting frame 3, and drives the screening mechanism 22 to be located directly below the sampling tube 4 through the cooperation of the connecting gear 24 and the connecting rack 23. At this moment, the partition is driven to slide out of the collection frame 11 through the reset mechanism 18, and the soil samples 26 inside the multiple modules are discharged one by one in the journey inside the collection frame 11. The screening mechanism 22 is provided with a feeding hole 221 for feeding the soil sample 26. At this moment, the screening mechanism 22 will screen the soil samples 26 entering the screening mechanism 22 one by one, and finally obtain the result, which can improve the work efficiency and avoid the mixing of soil samples 26 of different depths, improve the accuracy of the data in the later soil sample detection, and greatly meet the work needs.

[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 embodiment provided by the present invention, the driving mechanism 16 includes a threaded rod threadedly connected to the partition, specifically, the threaded rod is rotatably connected to the sampling tube 4, and the partition in the present embodiment includes a first partition plate 13, a second partition plate 14 and a third partition plate 15, so 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 drive gear 163, a second drive gear 164 and a third drive gear 165, which are respectively installed on the corresponding threaded rod. And a driving plate 162 is vertically slidably connected inside the sampling tube 4, and a meshing section 166 adapted to the gear unit is provided on the driving plate 162, specifically, there are three meshing sections 166, which are respectively meshed with the first drive gear 163, the second drive gear 164 and the third drive 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, and the trigger rod 161 is intermittently abutted with the trigger plate 6. Specifically, the trigger rod 161 is slidably connected with the driving tube 104 to meet the working needs. Therefore, during use, when the power mechanism 5 is used to drive the sampling tube 4 to slide upward for a certain distance, the trigger rod 161 at this moment abuts against the trigger plate 6, and as the sampling tube 4 continues to slide upward, the trigger plate 6 generates a downward sliding force for the trigger rod 161, thereby driving the trigger rod 161 to drive the driving plate 162 to slide downward. At this moment, since the meshing section 166 is meshed with the first driving gear 163, the second driving gear 164 and the third driving gear 165, the three threaded rods will be driven to rotate together, so that the first partition plate 13, the second partition plate 14 and the third partition plate 15 slide into the inside of the collection frame 11, so that the soil sample 26 inside the collection frame 11 is divided into multiple modules. At this moment, there will be no collapse and disordered layers between the soil samples 26, 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 guaranteed, 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 pressure part 19 includes a pressure rack 193 slidably connected to the frame 1, the pressure rack 193 is fixedly connected to the pressure rod 191 through the pressure plate 192, a driving frame 185 is fixedly connected to the reset plate 181, the pressure rod 191 and the driving frame 185 are intermittently abutted, and a trigger unit is arranged between the connecting block 201 and the pressure rack 193. When the connecting block 201 continues to slide upward, the trigger unit drives the pressure rod 191 to drive the driving frame 185 to slide upward. In this embodiment, the trigger unit includes a connecting rod 196 rotatably connected to the frame 1, a first pressure gear 194 is installed on the connecting rod 196, and the first pressure gear 194 is meshed with the pressure rack 193; and a second pressure gear 195 is also installed on the connecting rod 196, and a power rack 198 is fixedly connected to the connecting block 201, wherein the power rack 198 is intermittently meshed with the second pressure gear 195. When the power mechanism 5 drives the connecting block 201 to slide upward continuously, the power rack 198 at this moment drives the second pressure gear 195 to rotate, and drives the pressure rack 193 to slide through the rotating rod 251 and the first pressure gear 194, and then drives the pressure rod 191 to slide horizontally on the frame 1. A wedge-shaped groove is provided on the driving frame 185. After the pressure rod 191 abuts against the wedge-shaped groove and the pressure rod 191 continues to slide, the reset plate 181 will be driven to slide upward through the driving frame 185 to meet the working needs. A reset spring 197 is provided between the pressure rack 193 and the frame 1. The elastic force of the reset spring 197 drives the pressure rod 191 away from the driving frame 185. Therefore, when there is no external force driving the pressure rod 191 to slide, the elastic force of the reset spring 197 drives the pressure rod 191 to slide in the opposite direction to avoid affecting the sampling operation of the sampling tube 4.

[0065] In the embodiment provided by the present invention, the linkage member 17 includes a linkage gear 171 rotatably connected to the inside of the sampling tube 4, a first linkage portion 172 is provided on the driving plate 162, and a second linkage portion 173 is provided on the reset plate 181. The first linkage portion 172 and the second linkage portion 173 are respectively meshed on both sides of the linkage gear 171, and a positioning portion 174 is provided on the reset plate 181. The positioning portion 174 drives the reset plate 181 to remain in the state of being located inside the sampling tube 4 without the action of external force. When the driving plate 162 slides downward, the reset plate 181 is driven to slide upward through the cooperation between the first linkage portion 172, the linkage gear 171 and the second linkage portion 173. After the reset plate 181 slides upward for a certain distance, the driving frame 185 is driven by the pressure portion 19 to drive the reset plate 181 to continue to slide upward, meeting the working needs.

[0066] In the embodiment provided by the present invention, the intermittent connector 25 includes a rotating rod 251 installed on the bottom of the driving screw 52, ​​and a plurality of groups of ratchets 253 are installed on the rotating rod 251 through the base 252. A tooth groove 254 adapted to the ratchets 253 is provided on the connecting gear 24, and the ratchets 253 are clamped in the tooth groove 254. Specifically, a torque spring and a blocking portion are provided between the ratchets 253 and the base 252, so that the ratchets 253 can only rotate counterclockwise and cannot rotate clockwise in the original state. In this embodiment, when the driving screw 52 rotates forward, the ratchets 253 are driven to rotate clockwise through the rotating rod 251. At this moment, the arc surface of the back of the ratchets 253 abuts against the wedge surface of the tooth groove 254, and the ratchets 253 are passively driven to rotate counterclockwise, so that the connecting gear 24 cannot be driven to rotate. On the contrary, when the driving screw 52 is reversed, the ratchet 253 is driven to rotate counterclockwise through the rotating rod 251. At this moment, the end of the ratchet 253 is engaged in the tooth groove 254, which can drive the connecting gear 24 to rotate. The cooperation between the connecting gear 24 and the connecting rack 23 drives the screening mechanism 22 to slide to the bottom of the sampling tube 4, which facilitates the subsequent screening operation of the soil sample 26 and greatly improves the working efficiency of the device.
