When the sampling assembly completes sampling and resets, the closing assembly automatically completes the closing action of the closed door, so it effectively solves the problem of cumbersome use caused by the inability to form a linkage between the scraper and the sampling chamber, and then realizes that the closed door can be automatically closed after the sampling assembly completes sampling and resets, making the sampling operation more convenient.

[0051] In an embodiment of the present invention, when the electromagnet 231 is powered off, after the powered-off electromagnet 231 loses the magnetic attraction force on the driving gear 214 (the driving gear 214 is made of metal or magnetic material), the elastic force of the return spring 232 drives the driving gear 214 to slide along the transmission tube 212 to a position meshed with the second tooth groove rail 31. A limiting end is provided at the end of the transmission tube 212, which can axially limit the driving gear 214.

[0052] Please refer to Figure 7 、 Figure 8 and Figure 12 In an embodiment of the present invention, the rotating member 5 further includes a rotating plate 51, a rotating shaft 52, a third transmission gear 53 and a third key bar 56. The third transmission gear 53 and the rotating plate 51 are both fixedly connected to the rotating shaft 52. The second transmission gear 412 is drivingly connected to the third transmission gear 53. The rotating housing 54 is connected to the surface of the rotating plate 51. A third key bar 56 and a third key groove are respectively provided on the inner side of the rotating housing 54 and the outer side of the accommodating housing 61. The third key bar 56 is slidably connected to the third key groove.

[0053] Please refer to Figure 8 and Figure 9 Furthermore, the sample accommodating assembly 6 includes an accommodating housing 61, a column core 611, a fourth key bar 612, a mesh cover 62 and a tube core 621. The accommodating housing 61 is embedded in the rotating housing 54. The column core 611 is fixedly connected to the accommodating housing 61. A tube core 621 is provided on the surface of the mesh cover 62. The tube core 621 is movably sleeved on the surface of the column core 611. A fourth key bar 612 and a fourth key groove are respectively provided on the surface of the column core 611 and the inner side of the tube core 621. The fourth key bar 612 is slidably connected to the fourth key groove.

[0054] In an embodiment of the present invention, the number of the rotating housings 54 is three or four groups. The inner diameter of the accommodating housing 61 is larger than the outer diameter of the mesh cover 62, and the length of the mesh cover 62 is less than the depth of the accommodating housing 61.

[0055] Working principle: The driving motor is used to control the rotation of the drill shaft 111, the rigid tube shell 12 and the drill bit 13. When the drill bit 13 drills into the ground to a certain depth, the electromagnet 231 is first controlled to be powered off. Since the electromagnet 231 loses its magnetic attraction to the driving gear 214 after the power is turned off, the elastic force of the return spring 232 drives the driving gear 214 to slide along the transmission tube 212 to a position meshing with the second tooth groove rail 31. Since a limited end is provided at the end of the transmission tube 212, the driving gear 214 can be axially limited. The driving motor is used to control the rotation of the transmission tube 212, the driving gear 214 and the sealing cylinder 3, so that one of the first openings 32 is aligned with the radial sample inlet 125.

[0056] Then, the electromagnet 231 is controlled to be energized. When the electromagnet 231 after being energized is magnetically attached to the driving gear 214, the driven gear 221 is connected to the driving gear 214 by transmission. The driving motor is used to control the transmission tube 212, the driving gear 214, the driven gear 221 and the rotating tube 411 to rotate. The rotating rotating tube 411 controls the open serpentine shell 421, the center rod 422, the first fixing ring 423, the radial rod 424 and the second fixing ring 425 to make reciprocating linear motion by means of the curved guide rail 413 and the sliding connection with the ball head 426. At the same time, the open serpentine shell 421 can be controlled to rotate by the second key bar 414, the second key groove and the center rod 422. The open serpentine shell 421 that rotates and reciprocates on both sides of the radial sample inlet 125 and the first opening 32 can not only break up the agglomerated or bonded soil, but also pull the broken up soil into the axial sample inlet 121.

[0057] Since the rotating rotating tube 411 controls the rotating plate 51, the rotating shell 54 and the sample containing assembly 6 to rotate together with the rotating shaft 52 as the axis through the second transmission gear 412 and the third transmission gear 53, the soil can evenly enter the mesh cover 62 through the axial sample inlet 121. Since the rotating shell 54 rotating with the rotating shaft 52 as the axis is connected to the first toothed track 127 through the fourth transmission gear 55, the purpose of controlling the rotation of the rotating shell 54, the mesh cover 62 and the containing shell 61 is achieved. The centrifugal force generated by the rotating mesh cover 62 can quickly and effectively screen the soil with smaller particle size into the containing shell 61;

[0058] After sampling is completed, first, the driving module 2 is used to reset the open snake-shaped shell 421 into the rigid shell 12. Then, the driving module 2 is used to control the rotation of the sealing cylinder 3, so that another first opening 32 is aligned with the radial sample inlet 125. At this time, the access port 126 is aligned with the second opening 33. Next, the driving module 2 is used to control the simultaneous movement of the sampling module 4 and the rotating member 5. When the mesh cover 62 moves to the axial sampling port 123, the user takes out the mesh cover 62 and the accommodating shell 61 through the second opening 33 and the axial sampling port 123 in sequence, so as to facilitate the detection of soils with different particle sizes.

[0059] In summary, (1) The present application uses the open snake-shaped shell 421 that reciprocates inside and outside the rigid shell 12 while rotating, which can not only break up caked or agglomerated soil, but also pull the broken-up soil into the sample accommodating assembly 6, solving the problem of inconvenient sampling of soil with high viscosity or easy to agglomerate, and having the characteristic of convenient sampling.

[0060] (2) While the driving module 2 is used to control the sampling of the open snake-shaped shell 421, the present application can also control the sample accommodating assembly 6 to rotate simultaneously around the axis of the rotating member 5 and its own axis. It can not only evenly transport the soil into each sample accommodating assembly 6, but also screen soils with different particle sizes by using centrifugal force, having the characteristic of facilitating the detection of soils with different particle sizes.

[0061] (3) By using the driving module 2 to control the sealing cylinder 3 to rotate by several angles in sequence, the present application can not only seal the rigid shell 12 when the drill bit 13 drills the soil, but also align the first opening 32 with the radial sample inlet 125 during sampling, and can also align the access port 126 with the second opening 33 during detection, having the characteristics of facilitating adjustment and facilitating the access to the sample accommodating assembly 6.

These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
