[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of a modular soil sampling device, including a power component 1, which provides power to the entire soil sampling device. It contains a gasoline engine, which is existing technology. The engine drives a rotating shaft 2 through its output end, thereby driving subsequent components to work and realizing power transmission for soil sampling. A handle is provided on the outside for easy gripping and operation by the operator. The output end of the power component 1 is fixedly connected to the rotating shaft 2, which serves as an intermediate component for power transmission, transmitting the power output from the power component 1 to the connecting component 3 and the sampling component 4. The lower outer side of the rotating shaft 2 is fixedly connected to the connecting component 3 for connecting the sampling component 4, allowing the sampling component 4 to be modularly disassembled. The soil sampling component 4 is located at the lower part of the connecting component 3. Driven by the power component 1 and the rotating shaft 2, it rotates with the connecting component 3 and is inserted into the soil to obtain soil samples. This is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case.

[0036] Reference Figures 2-4 The connector 3 includes a connector 31 for connecting the rotating shaft 2 and the sampling component 4. The connector 31 is fixedly connected to the lower outer side of the rotating shaft 2. The rotating shaft 2 is connected to the connector 31 by bolts. The sampling component 4 is inserted into the lower inner wall of the connector 31. The inner wall of the connector 31 is fixedly connected to a limit post 32, which is provided in multiple sets. It engages with the L-shaped slot 33 on the upper part of the sampling component 4. When the sampling component 4 is inserted into the connector 31, it plays a role in initial positioning and restricting the circumferential rotation of the sampling component 4. The upper part of the sampling component 4 is evenly provided with three sets of L-shaped slots 33. The limit post 32 engages with the slot 33 to achieve the initial positioning of the sampling component 4. At the same time, the inner wall of the slot 33 is used to insert the connector 34. Under the action of the spring 37, the connector 34 is inserted into the slot 33 to limit the limit post 32 and further fix the sampling component 4 to prevent it from falling off during operation.

[0037] Reference Figures 3-5A connector 34 is slidably connected to the upper inner wall of the connector 31. The connector 34 is inserted into the inner wall of the slot 33. The lower part of the connector 34 is elongated, and the upper part is annular. The elongated lower part of the connector 34 can be inserted into the inner wall of the slot 33. The connector 34 fixes the sample 4 by cooperating with the slot 33. An operating cylinder 35 is fixedly connected to the outer side of the connector 34. The outer side of the operating cylinder 35 is provided with anti-slip texture to facilitate the operator's grip and application of force. The movable connector 34 moves up and down to connect or disconnect the connector 34 from the slot 33, thereby completing the installation and disassembly of the sampling component 4. The upper part of the connecting seat 31 is fixedly installed with a housing 36, which protects the internal components such as the connector 34 and spring 37, preventing dust, dirt and other debris from entering and affecting the normal operation of the components. The lower part of the housing 36 has multiple sets of through slots to provide space for the movement of the operating cylinder 35. The operating cylinder 35 and the connector 34 are installed with bolts, and the through slots facilitate the installation of the operating cylinder 35.

[0038] Furthermore, the outer shell 36 is positioned between the connector 34 and the operating cylinder 35. The connector 34 and the outer shell 36 are elastically connected by a spring 37. The spring 37 is vertically positioned, with its upper and lower ends contacting the inner wall of the outer shell 36 and the upper part of the connector 34, respectively. In its natural state, the spring 37 pushes the connector 34 downward, causing it to insert into the slot 33 and thus fix the sample 4. When the operator pulls the operating cylinder 35 upward, the spring 37 is compressed, and the connector 34 disengages from the slot 33, facilitating the removal of the sample 4. A fixing cylinder is fixedly connected to the upper part of the connecting seat 31, and the inner side of the outer shell 36 slides on the outer side of the fixing cylinder. A protrusion is provided at the lower part of the outer shell 36, which is inserted into the outer side of the connecting seat 31 and installed using screws.

[0039] Reference Figure 2 , Figure 6 and Figure 7 An auxiliary component 5 is rotatably connected to the lower part of the operating cylinder 35. The auxiliary component 5 includes a rotating cylinder 51, which is rotatably connected to the lower outer side of the operating cylinder 35. The lower part of the rotating cylinder 51 is convex, and a connecting column 52 is fixedly connected to the convex surface of the lower part of the rotating cylinder 51. During operation, the rotating cylinder 51 can rotate around the operating cylinder 35, driving the connecting column 52 to move within the limiting groove 53. Through the cooperation between the connecting column 52 and the limiting groove 53, the rotating cylinder 51 and the plug-in 34 are limited, improving the stability of the device during operation. A limiting groove 53 is opened on the front side of the connecting seat 31, and the connecting column 52 is engaged with the inner wall of the limiting groove 53. The limiting groove 53 is set in a "Z" shape. The "Z" shape restricts the movement path of the connecting column 52, preventing the plug-in 34 from loosening due to vibration generated during operation, thus improving the stability of the device.

[0040] Working principle: When the equipment needs to be installed, the upper part of the sampling piece 4 is aligned with the lower inner wall of the connecting seat 31 and inserted. At this time, the limiting post 32 on the inner wall of the connecting seat 31 will be engaged in the L-shaped slot 33 on the upper part of the sampling piece 4 to complete the initial positioning and prevent the sampling piece 4 from rotating circumferentially.

[0041] The connector 34 moves downward under the elastic force of the spring 37, and its lower elongated structure is inserted into the inner wall of the slot 33 and cooperates with the limiting post 32 to firmly fix the sampler 4 on the connecting seat 31, ensuring that it will not fall off during sampling. At the same time, the connecting post 52 at the bottom of the rotating cylinder 51 is engaged in the "Z"-shaped limiting groove 53 on the front side of the connecting seat 31.

[0042] At this point, the operator activates power component 1, whose output drives shaft 2 to rotate. Shaft 2 transmits power to connector 3, causing sampling component 4 to rotate synchronously, providing mechanical power for soil sampling. The operator holds the handle of power component 1 and vertically inserts the rotating sampling component 4 into the soil, using its rotation to cut the soil and complete the sampling.

[0043] When it is necessary to disassemble or replace the sampling component 4, the operator pulls the operating cylinder 35 upward and rotates the rotating cylinder 51, so that the connecting column 52 slides on the inner wall of the limiting groove 53. Then, the operator moves downward and rotates the rotating cylinder 51, so that the connecting column 52 passes through the limiting groove 53 and releases the limiting of the operating cylinder 35. At this time, the operator pulls the operating cylinder 35 upward again, so that the plug-in component 34 moves upward against the elastic force of the spring 37, and the plug-in component 34 disengages from the slot 33.

[0044] At this point, the sampling component 4 is unlocked and can be rotated directly and pulled out from the bottom of the connecting seat 31, releasing the limit on the limiting post 32, which improves work efficiency and facilitates cleaning of samples or replacement of different types of sampling components 4 to adapt to different soil environments or sampling needs.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
