Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a small handheld soil sampling device. Background Technology

[0002] Soil is the main body of nature, composed of layers of minerals of varying thicknesses. The differences between soil and the parent material lie in their morphology, physical properties, chemical properties, and mineralogical characteristics. In environmental remediation and the construction industry, it is necessary to frequently sample and test surface soil, which is typically done using soil sampling equipment.

[0003] To avoid damaging the original structure of the soil after sampling, a patent document with publication number CN219474995U describes a method where the side plates are detachable. After installing multiple side plates, they form a complete column. Soil is then taken, and the soil column can be removed by disassembling the side plates, maintaining its integrity. Because the removal method involves disassembling the side plates, no treatment is performed on the soil column itself, thus preserving its original characteristics as undisturbed soil.

[0004] Theoretically, based on the disclosed technical content, the implementation of the above structure is beneficial for protecting the original state of the soil after sampling. However, according to the description in the disclosed technical content, soil sampling can be performed after assembling several side plates into one unit. When sampling soil from different areas, several side plates need to be disassembled and the soil removed. When sampling soil from another area, the disassembled side plates need to be reinstalled before soil sampling can be performed. This disassembly and reinstallation method increases the time for soil sampling in different areas, thereby reducing the efficiency of soil sampling in different areas. Utility Model Content

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.

[0026] Please see Figure 1 , Figure 3 , Figure 8 and Figure 9 A small handheld soil sampling device includes a sampler body 1. The lower end of the sampler body 1 is movably connected to an outer plate 2 via a fastening bolt 3. The fastening bolt 3 connects the sampler body 1 to the outer plate 2, facilitating the removal of the sampler body 1 after soil extraction and preventing damage to the original soil sample. An insert plate 4 is fixedly installed at the lower end of the outer plate 2, allowing the outer plate 2 to be inserted into the soil. A locking block 5 is fixedly connected to the upper surface of the sampler body 1. The inner wall of the locking block 5 is movably engaged with a fixing block 6 via a connecting component 7. The connecting component 7 connects the locking block 5 to the fixing block 6. By changing the connection method between 7 and the locking block 5, the entire removal of several outer side plates 2 can be achieved, allowing staff to collect soil samples from different areas. The outer end of the connecting component 7 is fixedly installed with a mounting plate 8 located outside the fixing block 6. The inner wall of the mounting plate 8 is movably connected with a limiting component 9, which is installed inside the mounting plate 8, thus restricting the position of the connecting component 7. A handrail 10 is movably connected to the top of the sampler body 1, which facilitates the use of the sampling equipment. The lower end of the sampler body 1 is fixedly installed with an inner side plate 11 located inside the outer side plate 2. The inner side plate 11 provides support and a platform for the installation of the outer side plate 2, and the inner side plate 11 is movably connected to the outer side plate 2 by fastening bolts 3.

[0027] The left and right sides of the inner wall of the locking block 5 are respectively fixedly installed with protrusions 12 located outside the fixing block 6. The front and rear sides of the locking block 5 are respectively provided with through holes 13, and the inner wall of the through hole 13 is movably connected with the outer wall of the connecting component 7. By changing the connection method between the through hole 13 and the connecting component 7, the removal of several outer side plates 2 can be achieved.

[0028] Please see Figure 2 , Figure 6 and Figure 7A baffle 14 is fixedly installed on the upper end of the fixing block 6. Annular blocks 15 for fixing the limiting component 9 are fixedly connected to the front and rear sides of the baffle 14. The annular blocks 15 are used to connect the fixing block 6 and the limiting component 9. A round rod 16 located below the handrail 10 is fixedly installed on the upper surface of the baffle 14. Grooves 18 are opened on the left and right sides of the fixing block 6, and the inner wall of the groove 18 is movably engaged with the outer wall of the protrusion 12. The movably engaged connection method restricts the installation position of the fixing block 6 in the engaging block 5. A threaded rod 17 is threadedly sleeved on the inner wall of the round rod 16.

[0029] The connecting assembly 7 includes a first spring 701, a connecting block 702, and a slider 703. The inner end of the first spring 701 is fixedly connected to the inner wall of the fixed block 6. The first spring 701 connects the fixed block 6 and the connecting block 702. The end of the first spring 701 away from the fixed block 6 is fixedly connected to the inner side of the connecting block 702. The outer wall of the connecting block 702 is evenly distributed with sliders 703 located inside the fixed block 6, and the outer end of the slider 703 is slidably connected to the inner wall of the fixed block 6. The sliding of the slider 703 within the fixed block 6 strengthens the stability of the movement of the connecting block 702. The outer side of the connecting block 702 is fixedly connected to the inner side of the mounting plate 8, and the outer wall of the connecting block 702 is movably sleeved with the inner wall of the through hole 13.

[0030] Please see Figure 4 and Figure 5 The limiting component 9 includes a sleeve rod 901, a limiting rod 902, and a second spring 903. The inner wall of the sleeve rod 901 is movably sleeved with the outer wall of the limiting rod 902, and the outer wall of the limiting rod 902 is movably sleeved with the inner wall of the mounting plate 8. The upper end of the limiting rod 902 is fixedly connected with the lower end of the second spring 903. The second spring 903 is used to connect the limiting rod 902 and the sleeve rod 901. The upper end of the second spring 903 is fixedly connected with the top surface of the inner wall of the sleeve rod 901, and the upper end of the outer wall of the sleeve rod 901 is fixedly sleeved with the inner wall of the annular block 15. By changing the connection method between the limiting rod 902 and the mounting plate 8, the connecting component 7 can be moved and fixed.

[0031] Sponge pads 19 are fixedly fitted on the left and right sides of the outer wall of the handrail 10. Anti-slip textures 21 are evenly distributed on the outer wall of the sponge pads 19. The anti-slip textures 21 increase the friction between the worker's hand and the contact surface of the handrail 10. A rectangular block 20 is fixedly fitted in the middle of the outer wall of the handrail 10, and the lower end of the rectangular block 20 is fixedly connected to the upper end of the threaded rod 17.

[0032] Working principle: In use, firstly, adjust the position of the handrail 10 according to the user's height. Due to the threaded connection between the threaded rod 17 and the round rod 16, the threaded rod 17 can rotate in a circular motion while also achieving vertical lifting and lowering. Simultaneously, the movement of the threaded rod 17, connected by the rectangular block 20, drives the handrail 10 to move in the same direction. Then, the outer plate 2 is inserted into the soil via the insert plate 4. After the soil collected from the inner side of the outer plate 2 is removed, the compression of the second spring 903 retracts the limiting rod 902 into the sleeve rod 901, separating the limiting rod 902 from the mounting plate 8. Afterwards, press the connecting block 702 towards the fixed... The internal movement of the fixed block 6 compresses the first spring 701 as the connecting block 702 moves, until the connecting block 702 separates from the annular block 15. The fixed block 6 can then be removed from the inside of the locking block 5, allowing the outer plate 2 to be disassembled and the soil on the inside of the outer plate 2 to be replaced. Finally, a new outer plate 2 is installed, allowing workers to sample soil from different locations. The rebound of the first spring 701 pops the connecting block 702 out of the annular block 15, and the rebound of the second spring 903 inserts the limiting rod 902 into the inside of the mounting plate 8, allowing the limiting component 9 to position the connecting component 7, thereby improving the tightness of the outer plate 2 installation.
