[0003] Currently, when sampling soil profiles, most methods involve directly digging up the soil from the profile using tools. In this sampling method, the soil at the top tends to fall to the bottom, resulting in uneven sampling and inaccurate test results. Utility Model Content

[0004] The purpose of this invention is to provide a soil profile stratification sampler to address the aforementioned shortcomings in the technology.

The other end of each of the two limiting rods is fixedly connected to a connecting plate. The connecting plate is disposed on the outside of the connecting block. A spring groove is provided in the middle of the outer side of the connecting block. A return spring is fixedly disposed inside the spring groove. One end of the return spring is fixedly connected to the inner side of the connecting plate to facilitate limiting and fixing the connecting block.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6 The soil profile stratified sampler shown includes:

[0027] The sampling frame 1 has multiple dividing and cutting plates 2 inside, which divide the sampling frame 1 into multiple sampling chambers 3. A second handle 16 is provided at the middle of the front end of the sampling frame 1, and the two ends of the second handle 16 are fixedly connected to the two sides of the sampling frame 1 respectively.

[0028] The movable groove 4 is located at the front end of the sampling frame 1. Multiple partition cutting plates 2 are fixedly connected to the front ends of each movable block 5. Multiple movable blocks 5 are located inside the movable groove 4. A connecting block 6 is fixedly connected to the front end of each movable block 5. The connecting block 6 is located at the front end of the sampling frame 1. An indicator block 7 is fixedly provided at both ends of the connecting block 6. Scale lines 8 are machined on both sides of the front end of the sampling frame 1. The two indicator blocks 7 are respectively located inside the two scale lines 8. A limiting component is provided on the connecting block 6.

[0029] A cutting frame 9 is located at the rear end of the sampling frame 1, with its top end at the top of the sampling frame 1. A third handle 17 is fixedly installed at the top of the cutting frame 9. A limiting guide slider 18 is fixedly installed on the top of both sides of the sampling frame 1. A limiting guide groove 19 corresponding to the size of the limiting guide slider 18 is opened on both inner side walls of the cutting frame 9. The two limiting guide sliders 18 are respectively installed inside the two limiting guide grooves 19.

[0030] The limiting assembly includes two limiting rods 10 located on the outside of the connecting block 6. The front end of the sampling frame 1 has multiple limiting holes 11, which are respectively located on both sides of the movable groove 4. One end of each of the two limiting rods 10 passes through the connecting block 6 and extends into two of the limiting holes 11. The other end of each of the two limiting rods 10 is fixedly connected to a connecting plate 12. The connecting plate 12 is located on the outside of the connecting block 6. A spring groove 13 is located in the middle of the outside of the connecting block 6. A reset spring 14 is fixedly installed inside the spring groove 13. One end of the reset spring 14 is fixedly connected to the inner side of the connecting plate 12. A first handle 15 is fixedly installed on the outside of the connecting plate 12.

[0031] Based on the required volume and depth of soil to be sampled, pull the first handle 15 outward. The first handle 15 drives the connecting plate 12 to move outward. The connecting plate 12 drives the two limiting rods 10 to move outward and stretches the return spring 14. When one end of the two limiting rods 10 leaves the inside of the two limiting holes 11, move the connecting block 6 up and down. The connecting block 6 drives the two indicator blocks 7 to move up and down. At this time, observe the indication of the indicator block 7 on the scale line 8. In this way, the distance between each connecting block 6 can be obtained, and the depth of the connecting block 6 can also be obtained. When the connecting block 6 moves, it will drive the movable block 5 and the dividing cutting plate 2 connected to it to move. In this way, the position of multiple dividing cutting plates 2 can be obtained. Based on the known cross-sectional area of ​​the sampling frame 1, the volume of the sampled soil can be obtained.

[0032] After fixing the positions of each connecting block 6 and the dividing cutting plate 2, first remove the cutting frame 9 from the rear end of the sampling frame 1. Hold the sampling frame 1 and align the rear end of the sampling frame 1 with the section to be sampled. At this time, make the top of the sampling frame 1 flush with the ground, and then push the sampling frame 1 towards the section. You can push it manually or with the help of external tools. At this time, the rear end of the sampling frame 1 and the dividing cutting plate 2 will be inserted into the soil. Then insert the cutting frame 9 downwards so that the limiting guide slider 18 on the sampling frame 1 is engaged in the limiting guide groove 19 on the cutting frame 9. This can guide and position the insertion direction of the cutting frame 9. The cutting frame 9 can be inserted manually or with the help of external tools. When the cutting frame 9 is fully inserted, remove the sampling frame 1 and the cutting frame 9 from the section. In this way, multiple soil samples will be taken out from the multiple sampling chambers 3 at the same time, so that the multi-layer soil sampling of the section can be completed directly in one go.

[0033] This invention adjusts the positions of multiple connecting blocks 6 and the dividing cutting plate 2, and uses a limiting component to limit and fix the positions of the connecting blocks 6 and the dividing cutting plate 2. It can be applied to soil sampling of different volumes and depths. During sampling, the cutting frame 9 cuts and limits the soil samples inside the multiple sampling chambers 3, allowing for sampling of different layers of samples at once, and avoiding the situation where the upper soil sample falls to the bottom. This makes the soil sampling more accurate and uniform, and thus makes the measurement results more accurate. This embodiment specifically solves the problem in the prior art that when sampling soil profiles, the soil is mostly dug out directly with tools. In this sampling method, the upper soil is easy to fall to the bottom, which leads to uneven sampling and inaccurate measurement results.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
