[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0026] Please refer to Figures 1-8 , the present utility model provides the following technical solutions: A soil sampling device includes an outer cylinder 1. A through hole 14 is connected through the outer wall of the outer cylinder 1. There are multiple through holes 14, corresponding to soil layers at different depths respectively. A rotating cylinder 2 is inserted inside the outer cylinder 1. Refer to the attached Figure 1 , the attached Figure 2 , the attached Figure 5 , the attached Figure 6 and the attached Figure 7, a butt joint hole 25 is connected through the outer wall of the rotating cylinder 2. There are multiple butt joint holes 25, and the butt joint holes 25 are aligned with the through holes 14 and have the same size. A sampling assembly 3 is inserted inside the rotating cylinder 2. The sampling assembly 3 includes a first sampling frame 31 and a second sampling frame 32. A first sampling cylinder 311 is fixed on the side wall of the first sampling frame 31. The first sampling cylinder 311 penetrates through the butt joint hole 25 and the through hole 14. A second sampling cylinder 321 is fixed on the side wall of the second sampling frame 32. The second sampling cylinder 321 penetrates through the butt joint hole 25 and the through hole 14. The two groups of sampling cylinders are arranged staggeredly and correspond to soil layers of different depths respectively. An insertion rod 4 is inserted between the first sampling frame 31 and the second sampling frame 32; when this solution is used, after inserting the outer cylinder 1 into the soil, the sampling cylinder is aligned with the butt joint hole 25 and the through hole 14 by rotating the rotating cylinder 2. Subsequently, by inserting the insertion rod 4 between the two sampling frames, the two groups of sampling cylinders move outward and are inserted into the external soil layer, thereby realizing the sampling operation. It can sample soil layers of different depths at the same time, and the samples taken are all inside the sampling cylinder, avoiding the situation of sample mixing at multiple positions when the samples are taken later, which is convenient for subsequent evaluation and analysis.
[0027] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, specifically, first moving handles 11 are symmetrically fixed to the outer wall of the upper end of the outer cylinder 1 for pressing down or pulling the outer cylinder 1 to move. Second moving handles 21 are symmetrically fixed to the outer wall of the upper end of the rotating cylinder 2 and can be used to rotate the cylinder body. The second moving handles 21 are located above the first moving handles 11. A sealing soft pad 26 is fixed to the outer wall of the rotating cylinder 2. There are multiple sealing soft pads 26, and the size of the sealing soft pad 26 is adapted to the size of the through hole 14. When the sealing soft pad 26 is engaged with the through hole 14, it can prevent external soil from entering the inside of the outer cylinder 1. The size of the rotating cylinder 2 is adapted to the inner size of the outer cylinder 1, that is, the outer wall of the rotating cylinder 2 fits against the inner wall of the outer cylinder 1 with a small gap to prevent soil from entering. A limiting cylinder 22 is fixed to the lower end of the rotating cylinder 2. A positioning rod 24 is fixed to the inner wall of the limiting cylinder 22. The lower end of the first sampling frame 31 is fixed with a first positioning plate 314. A first guiding hole 315 is provided on the first positioning plate 314. The positioning rod 24 passes through the first guiding hole 315. The lower end of the second sampling frame 32 is fixed with a second positioning plate 324. A second guiding hole 325 is provided on the second positioning plate 324. The positioning rod 24 passes through the second guiding hole 325, enabling the two sampling frames to move along the positioning rod 24. A compression spring 33 is fixed between the first positioning plate 314 and the second positioning plate 324. The compression spring 33 is located outside the positioning rod 24 and can pull the two sampling frames towards the middle of the positioning rod 24. A first dial plate 312 is fixed to the top of the first sampling frame 31, and a second dial plate 322 is fixed to the top of the second sampling frame 32 for combining the sampling frames on both sides. After collecting the samples in this solution, by pulling out the insertion rod 4, the compression spring 33 can pull the sampling frames on both sides towards the middle. At the same time, in cooperation with the operator pressing the two top dial plates, the sampling frames on both sides can be combined together, so that the sampling cylinder extending out of the outer cylinder 1 retracts into the inside of the rotating cylinder 2. At this time, the end of the sampling cylinder is located inside the docking hole 25, which can prevent the outside soil from entering the inside of the rotating cylinder 2. At the same time, the operator rotates the second moving handle 21, and the rotating cylinder 2 can drive the sampling cylinder to rotate, so that the end of the sampling cylinder fits against the inner wall of the outer cylinder 1 to avoid the leakage of the inner soil sample. At the same time, the through hole 14 on the outer cylinder 1 is blocked by the sealing soft pad 26 to prevent soil from entering through the through hole 14 when the outer cylinder 1 moves. Subsequently, the operator can pull out the entire outer cylinder 1 from the soil to complete the sampling operation, and the operation is convenient.
[0028] Refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, specifically, a first retaining ring 12 is fixed to the lower end of the inner wall of the outer cylinder 1. A second retaining ring 13 is provided below the first retaining ring 12. A third retaining ring 23 is fixed to the outer wall of the limiting cylinder 22. The third retaining ring 23 is located between the first retaining ring 12 and the second retaining ring 13. The first retaining ring 12, the second retaining ring 13, and the third retaining ring 23 are all made of flexible materials. In this solution, the third retaining ring 23 is limited by the upper and lower retaining rings, so that the rotating cylinder 2 always rotates at the same height, that is, the docking hole 25 is always kept at the height aligned with the through hole 14, which is convenient for the subsequent sampling cylinder to extend for sampling. At the same time, the setting of the flexible material is convenient for subsequently pulling out the rotating cylinder 2 and taking out the soil sample.
[0029] Referring to Figure 8 As shown, specifically, a first guiding inclined plate 313 is fixed to the lower side wall of the first sampling frame 31. A second guiding inclined plate 323 is fixed to the lower side wall of the second sampling frame 32. The lower end of the inserting rod 4 is in a sharp cone shape. The two guiding inclined plates can limit and support the inserting rod 4 to prevent the situation that the inserting rod 4 is inserted excessively and damages the bottom spring.
[0030] The working principle and usage process of the present utility model: When the present utility model is used for soil sampling, the operator holds the outer cylinder 1 and inserts it into the soil. Before insertion, the sealing soft pad 26 on the rotating cylinder 2 is clamped inside the through hole 14 on the outer cylinder 1. When the outer cylinder 1 is inserted completely, the operator rotates the second moving handle 21 to drive the rotating cylinder 2 to rotate, so that the sealing soft pad 26 moves out from the inside of the through hole 14, and at the same time, the docking hole 25 is aligned with the through hole 14. At this time, the sampling cylinder with one end clamped inside the docking hole 25 is facing the through hole 14. Then the operator can insert the inserting rod 4 into the inside of the rotating cylinder 2, so that the inserting rod 4 pushes the first sampling frame 31 and the second sampling frame 32 on both sides to move outward, so that the two groups of sampling cylinders penetrate the through hole 14 and insert into the external soil layer. Then the operator pulls out the inserting rod 4, and moves the two sampling frames towards the middle by the contraction spring 33 and the top dial plate, so that the sampling cylinder retracts into the inside of the rotating cylinder 2. At this time, the soil sample is retained inside the sampling cylinder. Then the operator rotates the second moving handle 21 again, so that the sealing soft pad 26 blocks the through hole 14 again, and at the same time, the end of the sampling cylinder fits against the inner wall of the outer cylinder 1 to prevent external soil from entering the inside of the outer cylinder 1. Then the whole outer cylinder 1 is pulled out to take out the soil samples at different depths. Then the operator pulls out the rotating cylinder 2 from the inside of the outer cylinder 1 and takes out the soil sample, which is convenient to operate.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
