[0049] The specific application of the first embodiment is as follows: when the entire sampler is sampling the soil surface to be monitored, first, the entire sampler is placed on the soil surface to be sampled, and then the entire sampler is adjusted before soil sampling to adapt to the uneven soil surface to be sampled. When the entire sampler is placed at the sampling location of the soil to be sampled, the external controller (the external controller is a prior art, not shown in the figure, and will not be described in detail here) starts the drive motor 307 in a forward or reverse direction (the forward or reverse movement of the drive motor 307 can be specifically controlled by the PL in the external controller). C control panel to achieve, which is the prior art and will not be elaborated here), drives the threaded screw 308 fixed to the output shaft of the driving motor 307 to rotate forward or reversely on the side surface of the first threaded hole 705 penetrating through the top of the other L-shaped slide 701, and thereby performs circumferential rotation limiting through the sliding hole 704 penetrating through the top of the L-shaped slide 701 and the sliding cooperation between the guide rod 306, so that the lifting ring 702 fixed between the two L-shaped slides 701 synchronously moves up and down back and forth inside the vertical cylinder 302. When the L-shaped When the lifting ring 702 fixed between the slide plates 701 synchronously moves up and down back and forth inside the vertical cylinder 302, the sliding process of the toggle rod 803 in the sampling member 8 inside the spiral groove 303 penetrating the vertical cylinder 302 drives the rolling balls 807 on the two U-shaped frames 806 to rotate and cooperate respectively to roll back and forth in the two rolling grooves 706 synchronously, and during the rolling process, the sliding cooperation between the arc plate 802 and the annular groove 703 is used to limit the position, so that the sampling member 8 moves up and down back and forth on the lifting member 7. At the same time, it also synchronously rotates back and forth in the circumferential direction, thereby completing the whole process of the rotary cutting sampling and separation process of the sampling member 8 and the soil to be sampled (when the rotary sampling cutting and separation of the soil to be sampled is performed, as the sampling member 8 moves up and down and rotates back and forth in the circumferential direction on the lifting member 7, the plurality of fixing members 5 that are slidably matched on the bracket member 3 are synchronously plugged, fixed and separated from the soil to be sampled), preventing the sampling member 8 from being misaligned when rotating back and forth in the circumferential direction on the lifting member 7, so as to avoid affecting the subsequent rotary cutting sampling and separation process; When the sampling blade 805 provided in the sampling piece 8 moves up and down back and forth inside the positioning vertical cylinder 302 and synchronously rotates in a circumferential direction, the sampling blade 805 provided in the sampling piece 8 can synchronously perform rotary cutting sampling and rotary cutting separation of the soil at the sampling location of the soil to be sampled. After the rotary cutting sampling is completed, the sampling blade 805 provided in the sampling piece 8 gradually separates from the rotary cut soil sampling block during the reverse rotation operation, until the sampling blade 805 is completely separated from the rotary cut soil sampling block, and the several fixing members 5 in the entire sampler are synchronously separated from the soil to be sampled, so as to transfer the sampler that has completed the sampling operation later; After the rotary cutting sampling and separation process is completed in the whole process, the entire sampler is transferred from the sampling location of the soil to be sampled, and then the sampled soil after rotary cutting is clamped and removed by other external clamping tools (other external clamping tools are prior art, not shown in the figure, and will not be elaborated on here). After the clamping and removal operation is completed, the removed sampled soil is placed in a designated sampling container for storage, which is convenient for the later analysis of the main components of the sampled soil in the laboratory, so as to facilitate the staff to analyze whether the sampled soil is contaminated. During the whole process, there is no need for manual rotation sampling operation on the sampled soil, which saves human labor and is convenient for the workers to perform soil sampling operations on the soil to be sampled in different areas.

[0050] For example 2, please refer to Figure 1-13, the second embodiment is improved on the basis of the first embodiment as follows.

A semicircular ring 603 is fixed on the inner wall, and a plurality of second fixing holes 604 are formed through the top of the semicircular ring 603; a semicircular vertical plate 605 is fixed on the bottom of the rotating ring 601, and an oblique groove 606 is formed through the outer wall of the semicircular vertical plate 605; an arc groove 319 is formed on the peripheral side of the bottom ring plate 301; an arc bottom plate 320 is fixed on the outer peripheral side of the vertical cylinder 302 above the arc groove 319, and a support rod 321 is slidably fitted through the arc bottom plate 320, and an arc support plate 322 is fixed on the bottom of the support rod 321 inside the arc groove 319, and a lever 323 slidably fitted with the oblique groove 606 is fixed on the top of the support rod 321.

[0051] The specific application of the second embodiment is as follows: before the sampling and monitoring of the soil, the sampling device moves the entire sampler to the soil position where sampling is required, and thereby performs preparation work for the entire sampler before soil sampling. When sampling the soil in the area to be monitored, the second threaded hole 404 opened on the outer top of the L-shaped lifting plate 403 is driven to perform threaded rotation on the peripheral side of the threaded screw 308 through its rotational cutting sampling process, and thereby the entire moving part 4 is limited in circumferential rotation through the sliding cooperation between a plurality of T-shaped rails 402 and a plurality of U-shaped vertical plates 311, so that the entire moving part 4 can perform vertical movement in the vertical direction on the peripheral side of the vertical cylinder 302; When the entire moving member 4 is able to move vertically in the vertical direction on the outer peripheral side of the vertical cylinder 302, the inclined plates 405 in the moving members 4 and the key grooves 406 respectively penetrated on one side of the inclined plates 405 begin to slide on the peripheral side of the plurality of cross bars 504, and thereby provide a force for the radial movement of the plurality of vertical bars 502, so that the cross blocks 501 respectively fixed at the bottom of the plurality of vertical bars 502 respectively slide synchronously inside the cross grooves 316 respectively opened on one side of the plurality of extended bottom plates 309, so that the plurality of vertical bars 502 synchronously approach the center position of the bottom ring plate 301, and thereby drive The articulated arm 506 articulated between the first articulated seat 505 and the second articulated seat 508 is pressed downwardly relative to each other, so that the plurality of stabilizing cones 507 are synchronously slid downwardly in the plurality of sliding holes 314 and pass through the circular hole 312, thereby driving the plurality of stabilizing cones 507 to move downwardly synchronously through the process of rotary cutting sampling, and finally inserting into the soil to be sampled, so as to maintain the stability of the entire sampler during the rotary cutting sampling process, avoid the phenomenon of the entire sampler tipping over during the rotary cutting sampling process, prevent the entire soil sampling process from being affected, and ensure the accuracy of the later sampling sample monitoring; During the above process, if the ground of the soil to be sampled is uneven, the entire sampler can be driven to rotate the rotating ring 601 to drive the rotating groove 602 provided on the inner wall of the rotating ring 601 to rotate synchronously on the peripheral side of the top ring 317. When the rotating groove 602 provided on the inner wall of the rotating ring 601 rotates synchronously on the peripheral side of the top ring 317, the semicircular vertical plate 605 fixed on the bottom of the rotating ring 601 and the oblique groove 606 provided on the outer wall of the semicircular vertical plate 605 rotate synchronously. The lever 323 fixed on the top of the support rod 321 slides on its peripheral side surface (the lever 323 is long enough to ensure that it does not slide back out of the oblique groove 606 when sliding inside the oblique groove 606). When the semicircular vertical plate 605 fixed on the bottom of the rotating ring 601 and the oblique groove 606 penetrated through the outer wall of the semicircular vertical plate 605 synchronously slide on the peripheral side surface of the lever 323 fixed on the top of the support rod 321, since the oblique groove 606 penetrated through the outer wall of the semicircular vertical plate 605 is obliquely arranged, Therefore, when the lever 323 slides inside the oblique groove 606, there will be a certain height difference, so that when the lever 323 slides, it synchronously performs vertical movement in the vertical direction, driving the support rod 321 to synchronously perform vertical movement in the vertical direction on the arc bottom plate 320, thereby changing the sliding distance of the arc support plate 322 fixed at the bottom of the support rod 321 on the arc groove 319, so that the arc support plate 322 fixed at the bottom of the support rod 321 can be aligned with the uneven sampling soil surface. After the fitting is completed, the entire rotating part 6 is fixed by the plug-in cooperation between the external bolt or the fixing pin and the first fixing hole 318 and the second fixing hole 604, so as to prevent the entire sampler from tipping over on the uneven soil ground during the soil sampling process, thereby improving the applicability of the entire sampler, avoiding the entire sampler from tipping over during the rotary cutting sampling process, preventing it from affecting the entire soil sampling process, and ensuring the accuracy of the later sampling sample monitoring.
