[0021] An embodiment of the present invention provides a tool for sampling undisturbed soil, as Figures 1-5 shown. The tool for sampling undisturbed soil includes: a first protective plate 1; a second protective plate 2, the second protective plate 2 is arranged on one side of the first protective plate 1, and an empty bin for storing soil samples is provided between the first protective plate 1 and the second protective plate 2; two triangular rings 3, the two triangular rings 3 are respectively fixed at the bottoms of the first protective plate 1 and the second protective plate 2; two anti-slip films 4, the two anti-slip films 4 are respectively installed on the inner walls of the first protective plate 1 and the second protective plate 2; a limiting assembly, the limiting assembly is arranged on the first protective plate 1 and the second protective plate 2, and the limiting assembly is used to stabilize the first protective plate 1 and the second protective plate 2.

[0022] In this embodiment, the first protection plate 1 and the second protection plate 2 constitute the main frame of the undisturbed soil sampling tool. The design of the protection plate can protect the soil sample from external environmental interference during the sampling process, ensuring the integrity of the soil sample. The anti-slip film 4 can increase the friction between the protection plate and the soil, preventing the soil from slipping out of the sampling tool during the sampling process, ensuring the success rate of sampling and the integrity of the soil sample. The limiting component is used to stabilize the first protection plate 1 and the second protection plate 2, ensuring that the relative position between the two protection plates remains unchanged during the sampling process, preventing the protection plates from shifting due to soil pressure or other external forces, thereby damaging the structure of the soil sample.

[0023] In a further preferred embodiment of the present utility model, the limiting component includes two limiting plates 5, a clamping ring 6, and a plurality of fixing bolts 7. The two limiting plates 5 are respectively fixed on the first protection plate 1 and the second protection plate 2. The clamping ring 6 is movably sleeved outside the first protection plate 1 and the second protection plate 2. The inner wall of the clamping ring 6 is in contact with the outside of the first protection plate 1 and the second protection plate 2. The plurality of fixing bolts 7 are respectively threadedly installed on the two limiting plates 5, and the plurality of fixing bolts 7 are all threadedly connected to the clamping ring 6.

[0024] In this embodiment, the limiting plate 5 provides a fixed installation point for the clamping ring 6, and through cooperation with the fixing bolts 7, it can ensure that the relative position between the first protection plate 1 and the second protection plate 2 remains fixed. The clamping ring 6, as an annular structure, can surround the two protection plates, providing additional stability, and through threaded connection with the fixing bolts 7, the two protection plates are tightly fixed. The fixing bolts 7 are the key components connecting the limiting plates 5 and the clamping ring 6. By rotating the fixing bolts 7, the clamping ring 6 can be tightly fitted with the two protection plates, thereby fixing the positions of the two protection plates.

[0025] In a further preferred embodiment of the present utility model, a plurality of bayonet openings 11 are provided on both the first protection plate 1 and the second protection plate 2. A plurality of clamping sleeves 12 are clamped in the plurality of bayonet openings 11. A plurality of limiting rods 13 are slidably installed in the plurality of clamping sleeves 12. A plurality of limiting holes 14 are provided on both the plurality of clamping sleeves 12 and the plurality of limiting rods 13, and hot melt adhesive is injected into the plurality of limiting holes 14.

[0026] In this embodiment, the bayonet openings 11 are used to install the clamping sleeves 12, providing a space for the limiting rods 13 to slide and be fixed. The clamping sleeves 12 and the limiting rods 13 cooperate to form a ring body, which can clamp the two protection plates together, further increasing the stability of the first protection plate 1 and the second protection plate 2. By pouring hot melt adhesive into the limiting holes 14, the clamping sleeves 12 and the limiting rods 13 can be stabilized. Heating the hot melt adhesive can adjust the position of the limiting rods 13, facilitating the subsequent disassembly of the first protection plate 1 and the second protection plate 2.

[0027] In a further preferred embodiment of the present utility model, a mounting rod 9 is fixed to the top of the snap ring 6, a flange 10 is fixed to the mounting rod 9, a motor 15 is mounted on the top of the flange 10, and a speed reducer is provided between the output shaft of the motor 15 and the flange 10.

[0028] In this embodiment, the mounting rod 9 serves as a connecting member for fixing the flange 10 to the snap ring 6. The flange 10 is used to provide a stable mounting platform for mounting the motor 15. The motor 15 is used to provide a power source, and the speed reducer is used to reduce the rotational speed output by the motor 15 and increase the torque to ensure that the output rotational speed and torque meet the working requirements of the soil sample sampling tool.

[0029] In a further preferred embodiment of the present utility model, a fixing ring 16 is fixedly mounted on the motor 15, and a mounting plate 17 is fixedly mounted on the fixing ring 16. The mounting plate 17 can be mounted on a lifting device.

[0030] In this embodiment, the fixing ring 16 serves as a connecting member for connecting the motor 15 and the mounting plate 17. The fixing ring 16 can withstand the forces and vibrations generated during the operation of the lifting device. The mounting plate 17 is used to mount the motor 15 and the entire sampling tool on the lifting device.

[0031] In a further preferred embodiment of the present utility model, adjusting blocks are fixed to the bottoms of the plurality of fixing bolts 7, silicone gaskets 8 are mounted on the tops of the plurality of adjusting blocks, and the plurality of silicone gaskets 8 can respectively contact the bottoms of the two limiting plates 5.

[0032] In this embodiment, the adjusting block serves as an intermediate connecting member to allow adjustment of the fixing bolt 7. The silicone gasket 8 has good elasticity and wear resistance, which can ensure close contact between the fixing bolt 7 and the limiting plate 5, while reducing noise and wear caused by vibration or impact.

[0033] In a further preferred embodiment of the present utility model, the empty bin is cylindrical, anti-corrosion coatings are provided on both the first protective plate 1 and the second protective plate 2, and anti-slip patterns are provided on the plurality of adjusting blocks.

[0034] In this embodiment, the cylindrical design makes the empty bin have better structural stability and compressive performance, and is also convenient for storing and taking out soil samples. The anti-corrosion coating can effectively prevent moisture, salts and other corrosive substances in the soil from eroding the protective plate, thereby extending the service life of the protective plate and maintaining its good working state. The anti-slip pattern can increase the friction between the adjusting block and the operator's hand, preventing operation errors or safety hazards caused by slipping during the adjustment process.

[0035] In summary, compared with the related art, the present device can form an empty bin through the cooperation of the first protection plate 1 and the second protection plate 2 to sample and store soil. By separating the first protection plate 1 and the second protection plate 2, the soil can be completely exposed. By setting the motor 15 to drive the rotation of the first protection plate 1 and the second protection plate 2, the difficulty of the device penetrating deep into the ground can be reduced. The first protection plate 1 and the second protection plate 2 can be clamped and limited by the snap ring 6, increasing the stability of the first protection plate 1 and the second protection plate 2.
