[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, this utility model provides a soil sampling mechanism, including a pole 1, a mounting part 101 at the top of the pole 1, two sets of mounting grooves on opposite sides of the mounting part 101, and a handle 2 detachably mounted in the mounting groove; two sets of mounting rings 102 are also provided on one side of the pole 1, and a carrying component is detachably mounted on both sets of mounting rings 102; an assembly part 103 with external threads is also provided at the bottom of the pole 1, and a sampling component is detachably mounted on the assembly part 103. The mounting section 101 has mounting slots on both sides, where the handle 2 can be detachably installed. This allows for easy installation or removal of the handle 2 as needed. Furthermore, the handle 2 allows operators to more easily hold and control the entire sampling mechanism, facilitating adjustments to the sampling angle and force to ensure successful soil sampling. Two sets of mounting rings 102 are located on one side of the upright 1, on which carrying components can be detachably installed. This allows staff to easily carry or hand-transport the sampling mechanism, making it easier to move the equipment when sampling in complex terrain areas, thus increasing the device's portability.

[0027] The bottom end of the upright 1 is also provided with an assembly part 103 with external threads. The external threads enable the upright 1 to be connected to the sampling component by a threaded connection. The threaded connection has the characteristics of convenient disassembly and installation. In sampling work at different depths, the length and diameter of the sampling tube 4 required for shallow sampling and deep sampling are different. The appropriate sampling component can be quickly replaced through the threaded connection. When encountering different soil types, such as sandy soil and clay soil, there are different requirements for the material and structure of the sampling component. It can also be quickly replaced, thus adapting to diverse soil sampling work and further increasing the practicality of the device.

[0028] like Figures 1 to 4 As shown, an assembly section is provided on one side of the upright pole 1. An assist pedal 701 is rotatably mounted on the assembly section. A first magnetic block 702 and a second magnetic block 703 are correspondingly mounted on the assist pedal 701 and the upright pole 1, respectively, and are in contact with each other. Multiple sets of clamping blocks 801 are also provided on both sides of the upright pole 1, and two sets of gripping rods 2 are detachably secured within each set of clamping blocks 801. The assembly section on one side of the upright pole 1 has a rotatable assist pedal 701. The assist pedal 701 and the upright pole 1 are correspondingly equipped with the first magnetic block 702 and the second magnetic block 703, which, when in contact, can fix the position of the assist pedal 701. During sampling, the operator can press down on the assist pedal 701 to provide additional downward pressure for the sampling component to insert into the soil, reducing operational difficulty and improving sampling efficiency. When sampling is not required or the assist pedal 701 is not in use, it can be folded up by magnetic attraction, without occupying extra space, making the equipment easy to carry and store. The pole 1 is also provided with multiple sets of clamping blocks 801. The multiple sets of clamping blocks 801 can store the handle 2 when sampling is not required, preventing the handle 2 from being lost. At the same time, the multiple sets of clamping blocks 801 can also reduce the carrying area, further increasing the portability of the device.

[0029] like Figure 1 and Figure 3 As shown, the carrying component includes a shoulder strap 3, with hooks 201 at both ends. The two sets of hooks 201 are detachably mounted within two sets of mounting rings 102. A sponge-material anti-abrasion layer 301 is also provided on the side of the shoulder strap 3 closest to the upright pole 1. The hooks 201 at both ends of the shoulder strap 3 are detachably mounted within the mounting rings 102 of the upright pole 1, forming a simple carrying structure. Workers can carry the soil sampling device on their backs using the shoulder strap 3, facilitating movement in complex terrain or large areas for multi-point soil sampling and reducing the burden of prolonged hand-holding. The sponge-material anti-abrasion layer 301 on the side of the shoulder strap 3 closest to the upright pole 1, positioned between the shoulder strap 3 and the body, reduces friction between the shoulder strap 3 and the upright pole 1 at the contact points with the body, preventing discomfort from prolonged carrying, improving carrying comfort, and protecting clothing from wear and tear, further enhancing the usability of the device.

[0030] like Figure 3 , Figure 5 and Figure 6 As shown, the sampling assembly includes a sampling tube 4, and an assembly part 103 is threadedly connected to a connector 5. The bottom of the connector 5 is detachably connected to the sampling tube 4. An installation cavity 401 is also provided inside the connector 5, and the top end of the push rod 6 passes through the sampling tube 4 and is positioned within the installation cavity 401. Sliding holes are also provided on both sides of the connector 5. Two sets of limiting brackets 501 are positioned opposite each other on the outer surface of the connector 5 near the sliding holes. Two sets of limiting rods 502 are movably inserted into each set of limiting brackets 501, and a limiting block 503 is provided at the top end of the push rod 6. The bottom of the limiting block 503 contacts the top of the two sets of limiting rods 502. A first return spring 601 is provided between the push rod 6 and the installation cavity 401. Two sets of second return springs 602 are also provided between the two sets of limiting rods 502 and the two sets of limiting brackets 501, respectively. The assembly part 103 and the connector 5 are connected by threads, making operation convenient and allowing for quick installation and disassembly. The bottom of the connector 5 is detachable from the sampling tube 4, allowing for easy replacement of the appropriate sampling tube 4 to meet different soil testing needs. For example, a long sampling tube 4 can be used for deep soil testing, while a sampling tube 4 of a specific material can be selected for sandy soil testing. This improves work efficiency. Furthermore, it facilitates replacement when components are damaged, reducing maintenance costs.

[0031] Limiting frames 501 are installed beside the sliding holes on both sides of the connector 5. Limiting rods 502 pass through the limiting frames 501, and the limiting block 503 at the top of the push rod 6 contacts the top of the limiting rod 502. When the push rod 6 is pushed, the limiting rod 502 and the limiting block 503 work together to effectively limit the movement range of the push rod 6, prevent excessive displacement, and ensure the structural stability of the sampling assembly. The top of the push rod 6 passes through the sampling tube 4 and is placed in the mounting cavity 401 of the connector 5. After soil sampling is completed, the push rod 6 can smoothly push out the soil sample in the sampling tube 4 due to the action of the first return spring 601, which facilitates subsequent sample collection and analysis, reduces the cumbersomeness of manual operation, and increases the convenience of the device during use. The second return spring 602 allows the limiting rod 502 to quickly return to its original position after being pushed open, continuously exerting the limiting effect on the push rod 6, ensuring the smoothness and stability of the entire operation process, and further ensuring the stable sampling.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
