[0026] The sampling tube 1 is provided with a positioning mechanism 6, which includes a limiting groove provided on the inner side wall of the through groove 4, the inner side wall of the limiting groove is rotatably connected with a transmission rod 61, the transmission outer wall of the transmission rod 61 is fixedly connected with a first gear 62, the first gear 62 is meshed with the rack 5, the outer wall of the transmission rod 61 is slidably connected with an internal gear 63, the internal gear 63 is meshed with the first gear 62, one end of the internal gear 63 is elastically connected to the inner side wall of the limiting groove through a first spring 64, the inner side wall of the limiting groove is provided with a slide groove 65, a slider is slidably connected in the slide groove 65, one end of the slider extends out of the slide groove 65 and is fixedly connected to the inner gear 63; when working, through the setting of the positioning mechanism 6, in cooperation with the sealing plate and the pressing plate 3, the depth of the soil sampled by the sampling tube 1 can be accurately controlled, so as to achieve the soil depth fixed-point sampling effect and improve the soil detection accuracy, that is, according to the depth of the soil required by the sampling tube 1, the internal gear 63 can be pushed to move to disengage from the first gear 62, so as to release the inner gear 63. In addition to limiting the rotation of the first gear 62 and the transmission rod 61, that is, releasing the movement limit of the rack 5 and the pressing plate 3, the pressing plate 3 can be pulled to drive the sealing block 2 to move up, and in conjunction with the scale line set on the pressing plate 3, the distance that the pressing plate 3 drives the sealing block 2 to move can be accurately controlled until the sealing block 2 moves up to a specified height, and the inner gear 63 can be synchronously released. Under the pressure of the first spring 64, the inner gear 63 resets to cooperate with the slide groove 65 and limits the rotation of the first gear 62, that is, limits the movement of the pressing plate 3, and the sampling tube 1 can be vertically inserted into the soil at the sampling location to sample the soil.

[0027] Further, such as Figure 1 and Figure 2 As shown, both sides of the pressing plate 3 are fixedly connected with connecting plates 7, and the bottom end of the connecting plate 7 is fixedly connected with a positioning ring 8. When working, the depth of the sampling tube 1 inserted into the soil is positioned by setting the connecting ring and the positioning ring 8 in cooperation with the sealing block 2, and the sampler as a whole is balanced, that is, the pressing plate 3 moves while the positioning ring 8 is driven to move synchronously through the connecting plate 7.

During operation, the toggle block 9 can be arranged to facilitate the movement of the inner gear 63 by pushing the toggle block 9, thereby avoiding the limit groove opening being too small and inconvenient to operate.
[0029] Further, such as Figure 3 andFigure 4 As shown in the figure, an observation port is provided on one side of the outer wall of the sampling cylinder 1. A guide groove is provided on the inner side wall of the observation port. A guide block is slidably connected in the guide groove. One end of the guide block extends out of the guide groove and is fixedly connected to a shielding block 10. An auxiliary groove is provided on the inner side wall of the observation port. An auxiliary block 11 is slidably connected in the auxiliary groove. One end of the auxiliary block 11 is elastically connected to the inner side wall of the auxiliary groove through a second spring 12. The other end of the auxiliary block 11 extends out of the auxiliary groove. During operation, through the settings of the shielding block 10, the observation port, the auxiliary block 11 and the second spring 12, it is convenient to directly observe the sampled soil in the sampling cylinder 1 after sampling is completed, avoiding the soil from crumbling and mixing when the soil is pushed out of the sampling cylinder 1, which affects the detection accuracy. That is, after sampling is completed, press the auxiliary block 11 to release the movement limit of the shielding block 10, and pull out the shielding block 10, then the sample in the sampling cylinder 1 can be observed.
[0030] Further, as Figure 1 and Figure 2 shown, an observation port 13 is provided on one side of the outer wall of the shielding block 10. A transparent block is fixedly connected to the inner side wall of the observation port 13. During operation, through the settings of the observation port 13 and the transparent block, it is convenient to observe the soil sampling situation in the sampling cylinder 1 as needed without opening the shielding block 10.
[0031] Further, as Figure 1 and Figure 2 shown, a pushing block 14 is fixedly connected to one side of the outer wall of the shielding block 10. A sealing gasket is provided on the inner side wall of the observation port 13. During operation, through the setting of the pushing block 14, it is convenient to drive the shielding block 10 to move by pushing the shielding block 10, avoiding the smooth outer wall of the shielding block 10 and being inconvenient to apply force.
[0032] Further, as Figure 1 and Figure 2 shown, a pressing block 15 is fixedly connected to one side of the outer wall of the sampling cylinder 1. Anti-slip patterns are provided on the outer wall of the pressing block 15. During operation, through the setting of the pressing block 15, it is convenient to apply pressure to the pressing block 15 to further apply pressure to the sampling cylinder 1 to ensure balance.
[0033] Working principle: According to the depth of the soil where the sampling cylinder 1 is required, the internal gear 63 can be pushed to move it away from the first gear 62, releasing the rotational limit on the first gear 62 and the transmission rod 61, that is, releasing the movement limit on the rack 5 and the pressing plate 3. Then, the pressing plate 3 can be pulled to drive the sealing block 2 to move upward. With the scale line set on the pressing plate 3, the distance that the pressing plate 3 drives the sealing block 2 to move can be accurately controlled. Until the sealing block 2 moves up to the specified height, the internal gear 63 can be released synchronously. Under the pressure of the first spring 64, the internal gear 63 resets and cooperates with the chute 65 to limit the rotation of the first gear 62, that is, to limit the movement of the pressing plate 3. Then, the sampling cylinder 1 can be vertically inserted into the soil at the sampling location to sample the soil. However, after sampling the soil at the specified depth, the sampling cylinder 1 is full and no longer samples. The sampling cylinder 1 can be pulled out and the internal gear 63 can be pushed out again to release the limit on the pressing plate 3. The pressing plate 3 is pushed to cooperate with the sealing block 2 to push the sampled soil into the sample collector, and the bottom of the sealing block 2 and the sampling cylinder 1 are cleaned. Then, the soil sampling at the next location can be carried out. After the sampling is completed, the situation of the sampled soil can be directly observed inside the sampling cylinder 1 to avoid the soil crumbling and mixing when the soil is pushed out of the sampling cylinder 1, which affects the detection accuracy. That is, after the sampling is completed, the pressing auxiliary block 11 releases the movement limit on the shielding block 10, and the shielding block 10 is pulled out, then the sample inside the sampling cylinder 1 can be observed.
