[0058] The working principle of the soil sampling device for soil census provided by the present invention is as follows:

[0059] During actual use, first splice two semi-cylindrical bodies into a complete hollow cylindrical sampling tube 23. Then thread the first connecting ring 21 with a wire passing opening 26 to the top of the sampling tube 23. Then thread the second connecting ring 24 with a hanging rod 35 to the bottom of the sampling tube 23. Thus, a complete and firm sampling tube 23 is formed. Then insert the hook 28 into the top of the sampling tube 23 and hang the hook 28 on the hanging rod 35. After preparation, only need to insert the sampling tube 23 into the inside of the movable opening 20. Then loosen the limit bolt 6 to adjust the position of the movable plate 15 to align the pressing plate 18 with the movable opening 20. Then start the telescopic rod 14 to push the pressing plate 18 to contact the top of the first connecting ring 21. During this process, the steel wire 12 needs to be inserted into the inside of the wire passing opening 26. Use the thrust of the telescopic rod 14 to push the sampling tube 23 into the soil. If it is necessary to splice the sampling tube 23, only need to thread the bottom end of the assembled sampling tube 23 with the first connecting ring 21 so that the steel wire 12 is located between the two sampling tubes 23, then the sampling tube 23 can be extended, and the steel wire 12 will pass through the first first connecting ring. When it is necessary to take out the sampling tube 23 after sampling, only need to move the position of the movable plate 15 so that the wire reel 11 is above the movable opening 20. Then start the driving component 10 to drive the wire reel 11 to wind the steel wire 12, and the sampling tube 23 can be slowly pulled out of the soil. During this process, if it is necessary to disassemble the extended sampling tube 23, only need to stop the driving component 10, and then remove the extended sampling tube 23 from the first connecting ring 21. Since the steel wire 12 passes through the inside of the first section of the sampling tube 23, the disassembly of the extended sampling tube 23 is not affected. Since the top of the sampling tube 23 is open, it can ensure that the soil at the deepest position inside the first section of the sampling tube 23 gradually enters the inside of the sampling tube 23.

[0060] Compared with the related technology, the soil sampling device for soil census provided by the present invention has the following beneficial effects:

[0061] In order to facilitate the insertion of the plug-in sampling tube into the soil and its removal from the soil, two support frames 2 are installed on the movable chassis 1. Then, two mounting plates 8 with slide rails 7 are respectively installed on the tops of the two support frames 2. On one side where the two slide rails 7 are adjacent, a movable plate 15 that can be adjusted back and forth in position is installed through two slide bars 9. And after the movable plate 15 is adjusted to the proper position, it can be fixed by the limit bolt 6 on the slide rail 7. Then, only the pressure plate 18 needs to be installed below the movable plate 15 through the telescopic rod 14. After that, the winding wheel 11 with the steel wire 12 and the hook 28 is installed above the movable plate 15 through the rotating frame 13, and the hook 28 is made to pass through the through hole 19 to facilitate its connection with the hanging rod 35. And the winding wheel 11 is powered by the driving assembly 10. In order to increase the stability of the two support frames 2, two fixing plates 22 with movable openings 20 are installed between them. With this structure, the cooperation of the telescopic rod 14 and the winding wheel 11 with the hook 28 reduces the difficulty of the sampling tube 23 entering and being pulled out of the soil. At the same time, the sampling tube 23 with an open top allows the soil inside the sampling tube 23 to be clearly stratified, and soil samples with more accurate depths can be obtained, facilitating data collection during later soil surveys.

[0062] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention.
