Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Referring to Figures 1-4 , the present utility model provides an electric soil sampling device, including:

[0029] A drive motor 1, a handle is installed on the drive motor 1, and a speed regulator is installed at the output shaft end of the drive motor 1;

[0030] The hydraulic telescopic rod 2 is coaxially arranged with the drive motor 1, and the fixed end of the hydraulic telescopic rod 2 is fixedly connected to the output shaft of the speed regulator;

[0031] The distance adjustment frame includes a mounting plate 3 detachably connected to the fixed end of the hydraulic telescopic rod 2. A plurality of distance adjustment rods 4 are detachably connected to the mounting plate 3 at equal circumferential intervals, and a distance adjustment component is installed at the end of the distance adjustment rod 4;

[0032] The sampling bucket 5 is coaxially arranged with the hydraulic telescopic rod 2. A plurality of pressure grooves 6 are axially formed on the side wall of the sampling bucket 5. The plurality of pressure grooves 6 are arranged in one-to-one correspondence with the plurality of distance adjustment rods 4. The distance adjustment rod 4 is inserted into the pressure groove 6, and a positioning component is installed on the distance adjustment rod 4, and the positioning component abuts against the mounting plate 3; The end part of the sampling bucket 5 is circumferentially provided with serrated grooves;

[0033] The pushing component is installed in the sampling bucket 5, passes through the top wall of the sampling bucket 5 and is detachably connected to the output end of the hydraulic telescopic rod 2;

[0034] Wherein, a storage battery 7 is installed on the handle, and the storage battery 7 is electrically connected to the drive motor 1.

[0035] When the utility model is used, the distance adjustment rod 4 is installed on the mounting plate 3 through the positioning component, and then the distance adjustment rod 4 is inserted into the pressure groove 6 of the sampling bucket 5. The insertion depth of the distance adjustment rod 4 is adjusted through the distance adjustment component according to the sampling depth. The pushing component is connected to the end of the electric control telescopic rod. The drive motor 1 outputs power, the drive motor 1 adjusts the output speed through the speed regulator, and transmits the output power to the hydraulic telescopic rod 2, and drives the hydraulic telescopic rod 2 to rotate. The hydraulic telescopic rod 2 drives the sampling bucket 5 to rotate through the distance adjustment frame, and at the same time, the whole device feeds to complete soil sampling. After the soil sampling is completed, the positioning component is loosened, and the pushing component is driven by the hydraulic telescopic rod 2 to take out the soil sample in the sampling bucket 5.

[0036] The utility model realizes the adjustment of the soil sampling depth of the device through the cooperation of the distance adjustment component and the distance adjustment rod 4, improves the flexibility of the device for soil sampling, and ensures the soil sampling efficiency.

[0037] In a further optimized scheme, the positioning component includes a first positioning nut 8 and a second positioning nut 9. The first positioning nut 8 and the second positioning nut 9 are both threadedly connected to the distance adjustment rod 4, and the first positioning nut 8 and the second positioning nut 9 are respectively located on both sides of the mounting plate 3, and the first positioning nut 8 and the second positioning nut 9 respectively abut against both sides of the mounting plate 3.

[0038] The positioning of the distance adjustment rod 4 is realized through the cooperation of the first positioning nut 8 and the second positioning nut 9, and the installation stability between the distance adjustment rod 4 and the mounting plate 3 is ensured.

[0039] For a further optimized solution, the distance adjustment component includes a slide bar 10 fixedly connected to the end of the distance adjustment rod 4. The slide bar 10 is slidably connected in the pressure groove 6. An annular groove 11 is formed on the outer wall of the slide bar 10, and a sealing rubber ring 12 is installed in the annular groove 11. A pressure discharge hole 13 is formed on the side wall of the pressure groove 6, and a valve core 14 is installed in the pressure discharge hole 13.

[0040] In this embodiment, the end of the distance adjustment rod 4 is fixedly connected to the slide bar 10, and the sealing rubber ring 12 is installed on the slide bar 10, so that the slide bar 10 and the sealing rubber ring 12 form a piston structure, and a piston sleeve structure is formed between them and the pressure groove 6. When the slide bar 10 is inserted into the pressure groove 6 from the top, the gas inside the pressure groove 6 will be squeezed. At this time, the valve core 14 is controlled to open to discharge the pressure in the pressure groove 6, so that a relatively stable pressure difference is formed between the pressure groove 6 and the slide bar 10. When the slide bar 10 is inserted to a certain depth and then stops inserting and the valve core 14 is closed, the pressure at both ends of the slide bar 10 is stable. Pulling out the slide bar 10 will cause the pressure between the slide bar 10 and the pressure groove 6 to decrease, resulting in a change in the pressure at both ends, so that sliding beyond the preset distance cannot occur. At the same time, pushing inward will cause the gas in the space to be compressed, and long-distance sliding cannot occur either. Therefore, the slide bar 10 can be in a relatively stable state, ensuring that the distance adjustment rod 4 and the sampling bucket 5 are in a relatively stable state.

[0041] For a further optimized solution, a sealing nut is threadedly connected to the distance adjustment rod 4. The sealing nut abuts against the sampling bucket 5, and a sealing ring is provided between the sealing nut and the sampling bucket 5.

[0042] For a further optimized solution, the pushing component includes a push plate 15 slidably connected in the sampling bucket 5. One side of the push plate 15 is fixedly connected to a threaded sleeve 16. The output end of the hydraulic expansion rod 2 is provided with an external thread, and the threaded sleeve 16 passes through the bottom wall of the sampling bucket 5 and is threadedly connected to the end of the hydraulic expansion rod 2.

[0043] For a further optimized solution, through holes 17 are equidistantly formed on the mounting plate 3, positioning blocks 18 are fixedly connected to the inner walls of the through holes 17, and positioning grooves are formed on the outer wall of the distance adjustment rod 4. The positioning blocks 18 and the positioning grooves are slidably matched. The cooperation between the positioning blocks 18 and the positioning grooves can position the distance adjustment rod 4, ensure the stable sliding between the positioning rod and the mounting plate 3, so that the positioning rod can only slide along the vertical direction and will not rotate axially, avoiding rotating along with the first positioning nut 8 and the second positioning nut 9 during the distance adjustment process of the first positioning nut 8 and the second positioning nut 9.
