[0025] The soil samples are separated into four quadrants by using the shrinking component. The rectangular frame plate 1 and the tray 2 can be separated by opening the lock 3. The soil samples in the first and third quadrants remain inside the rectangular frame plate 1, and the soil samples in the second and fourth quadrants leave with the tray 2, thereby completing the shrinking of the soil samples. This not only avoids repeated mixing of the soil samples after shrinking, but also makes the soil samples after shrinking easier to split and merge.

[0026] The shrinking assembly includes a support rod 11, a first slide groove 12 for sliding the support rod 11 is provided on the third support column 9, a dispersion plate 13 is fixed to one end of the support rod 11, and a cross-shaped partition plate 14 is fixed to the other end of the support rod 11;

[0027] The conical soil sample pile can be dispersed into a disc shape along the circumference by using the dispersion plate 13. After reversing the positions of the dispersion plate 13 and the cross-shaped partition plate 14, the disc-shaped soil sample can be separated into four quadrants with the help of the cross-shaped partition plate 14, making the soil sample reduction operation more convenient.

[0028] The limiting assembly includes a spring 15, the top of which is fixedly mounted on the first support column 7, an end plate 16 is fixedly mounted on the bottom of the spring 15, a limiting rod 17 is fixedly mounted on the upper surface of the end plate 16, the spring 15 is sleeved on the outside of the limiting rod 17, a second sliding groove 18 for the limiting rod 17 to slide is provided on the first support column 7, and a card slot 19 adapted to the limiting rod 17 is provided on the third support column 9;

[0029] The position of the limiting rod 17 can be adjusted by manpower in cooperation with the spring 15, so that the limiting rod 17 can lock the third supporting column 9 with the first supporting column 7 after the third supporting column 9 rotates, thereby preventing the third supporting column 9 from further rotating.

[0030] The support assembly includes a carrier tube 20, which is fixedly mounted on the bottom of the tray 2, a stud 21 is inserted into the bottom of the carrier tube 20, and the carrier tube 20 is threadedly connected to the stud 21, and a bottom plate 22 is fixed to the bottom end of the stud 21;

[0031] By rotating the bottom plate 22, the combined length of the carrier tube 20 and the stud 21 can be adjusted, so that the four supporting components can adjust the lifted tray 2 to a horizontal state when the supporting surface is uneven, so as to better shrink the soil sample.

[0032] Working principle of this utility model:

[0033] Place the bottom of the rectangular frame plate 1 on the tray 2 so that the two first support plates 4 and the two second support plates 5 fit closely together, use four lock buckles 3 to lock the rectangular frame plate 1 and the tray 2, and place the four support components on the operating table. If the surface of the operating table is uneven, the bottom plate 22 in the low-lying area can be rotated so that the bottom plate 22 drives the studs 21 to rotate, and the overall length of the support component is adjusted until the tray 2 is in a horizontal state. Pile the conical soil sample pile in the middle of the rectangular frame plate 1, push the dispersion plate 13 to insert into the cone top, and rotate the dispersion plate 13 to disperse the soil sample pile along the circumference, and finally into a disc shape;

[0034] Subsequently, the dispersion plate 13 is pulled upward and away from the soil sample, and the end plate 16 is pulled downward so that the limiting rod 17 disengages from the slot 19. At this time, the third supporting column 9 is no longer restricted, and the third supporting column 9 can be rotated and the end plate 16 can be loosened. As the third supporting column 9 rotates 180°, the limiting rod 17 will be inserted into the slot 19 again with the help of the elastic force of the spring 15, thereby completing the locking of the position of the third supporting column 9. At this time, the dispersion plate 13 and the cross-shaped partition plate 14 are reversed in position, and the cross-shaped partition plate 14 is pushed downward so that the cross-shaped partition plate 14 divides the soil sample into four parts and places the soil sample in four quadrants. The four locks 3 are opened, and the rectangular frame plate 1 is separated from the tray 2. The soil samples in the first and third quadrants stay inside the rectangular frame plate 1, and the soil samples in the second and fourth quadrants will leave with the tray 2. Afterwards, the soil samples in the first and third quadrants are merged, and the soil samples in the second and fourth quadrants are merged, one part is discarded, and the other part is used as a sample, thus completing a reduction.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
