[0002] Soil sampling refers to the method of collecting soil samples, including the layout and sampling techniques of the samples. Before soil sampling, the surface soil of the area to be sampled needs to be scraped off, and then the soil samples are taken from top to bottom according to the layers;

[0003] The Chinese patent publication (publication number: CN216955232U) discloses a soil sampling device, comprising: an outer cylinder, whose upper end is a threaded hole 1, and whose lower end is a sliding hole 2, wherein the sliding hole 1 is between the threaded hole 1 and the sliding hole 2, and the aperture of the sliding hole 1 is larger than the aperture of the sliding hole 2; a stud, whose lower end extends into the outer cylinder and is screwed to the threaded hole 1, and the lower end of the stud is fixedly installed with a top column; a sliding block, which can only slide in the sliding hole 1 and is detachably connected to the top column; a sample storage cylinder, whose upper end slides through the sliding hole 2 and is fixedly connected to the sliding block, and whose lower end is fixedly connected with a drill bit; when the top column is connected to the sliding block, the rotation of the stud drives the sliding block and the sample storage cylinder to rotate synchronously.

The sleeve 401 is embedded in the interior of the supporting bottom plate 402. The top of the sleeve 401 is fixedly connected to the lower surface of the rectangular plate 1. The interior of the sleeve 401 is slidably provided with a fixing cone 403. The outer side of the fixing cone 403 is fixedly installed with a push rod 405. The inner wall of the sleeve 401 is provided with a rectangular hole 406. 06, a second limiting hole 408 is provided on the inner wall of the rectangular hole 406, a first limiting hole 407 is provided on the inner wall of the rectangular hole 406, the outer side of the push rod 405 is in sliding contact with the inner walls of the rectangular hole 406, the first limiting hole 407 and the second limiting hole 408, one end of the push rod 405 extends to the outside of the sleeve 401, a threaded hole 101 is provided on the upper surface of the rectangular plate 1, the internal thread of the threaded hole 101 is connected with a sleeve 2, the bottom end of the sleeve 2 is fixedly connected to the upper surface of the sampling tube 5, a first rotating handle 201 is fixedly installed on the outer side of the sleeve 2, an extrusion assembly 3 is arranged inside the first rotating handle 201, and the extrusion assembly 3 includes a threaded rod 301, a second rotating handle 302, an internal threaded tube 303, a push plate 304 and a scraper 305.

[0026] In one embodiment, an internal threaded barrel 303 is fixedly installed inside the sleeve 2, and the internal threads of the internal threaded barrel 303 are connected to a threaded rod 301. The top of the threaded rod 301 extends to the top of the sleeve 2, and a second rotating handle 302 is fixedly installed on the outside of the threaded rod 301. The bottom end of the threaded rod 301 extends to the inside of the sampling barrel 5, and a push plate 304 is fixedly installed on the bottom end of the threaded rod 301. A scraper 305 is fixedly installed on the outside of the push plate 304. The internal threaded barrel 303, the threaded rod 301, the push plate 304 and the scraper 305 make it easy to push out the soil in the sampling barrel 5.

[0027] In one embodiment, a mounting hole 404 is provided on the upper surface of the supporting base plate 402 , and the inner wall of the mounting hole 404 is fixedly connected to the outer side of the sleeve 401 , so that the sleeve 401 is fixed by the provision of the mounting hole 404 .

[0028] In one embodiment, the outer side of the scraper 305 is in active contact with the inner wall of the sampling tube 5 , so as to facilitate scraping off the soil adhering to the inner wall of the sampling tube 5 .

[0029] In one embodiment, a through hole 501 is opened at the top of the inner wall of the sampling tube 5 , and the inner wall of the through hole 501 is in sliding contact with the outer side of the threaded rod 301 , and the threaded rod 301 is guided by the provision of the through hole 501 .

[0030] In one embodiment, a thread groove threadably connected to the threaded hole 101 is provided on the outer side of the sleeve 2 , so that the sleeve 2 can move up and down through the threaded hole 101 .

[0031] When the utility model is working: the whole device is placed at the position of the soil to be sampled, the push rod 405 is toggled clockwise to make it slide along the second limiting hole 408, and at the same time, the push rod 405 drives the fixed cone 403 to slide. When the push rod 405 slides to contact the inner wall of one side of the rectangular hole 406, the push rod 405 is pushed downward along the rectangular hole 406. The push rod 405 moves and drives the fixed cone 403 to move downward to move the fixed cone 403 out of the sleeve 401. When the push rod 405 moves to contact the inner wall of one side of the first limiting hole 407, the push rod 405 is toggled counterclockwise to make it slide along the second limiting hole 408. 05, so that the push rod 405 is stuck in the first limiting hole 407, the push rod 405 is limited, and the fixing cone 403 is limited at the same time. At this time, the whole device is pushed downward, so that the fixing cone 403 is inserted into the soil until the lower surface of the supporting bottom plate 402 contacts the soil. The two fixing cones 403 can fix the whole device, improve the stability during sampling operation, and when sampling the soil, the first rotating handle 201 is rotated to drive the sleeve 2 to rotate, and the sleeve 2 drives the sampling tube 5 to rotate and move downward, and insert it into the soil to perform sampling operation;

[0032] After sampling is completed, the entire device is pulled upward to remove the two fixed cones 403 from the soil, and the push rod 405 is moved clockwise again to slide along the first limiting hole 407 and upward along the rectangular hole 406. When the push rod 405 moves to contact the top of the inner wall of the second limiting hole 408, the push rod 405 is moved counterclockwise to limit the push rod 405 and the fixed cone 403 at the same time, so that the fixed cone 403 can be stored in the sleeve 401 again, which makes it easy to store the fixed cone 403 and effectively avoids the fixed cone 403 from being exposed. When the sample needs to be taken out, the second rotating handle 302 is rotated to drive the threaded rod 301 to rotate, and the threaded rod 301 and the internal threaded tube 303 are threadedly matched to move downward, and the threaded rod 301 moves downward and drives the push plate 304 to move downward, and the push plate 304 moves and drives the scraper 305 to move, and the soil adhering to the inner wall of the sampling tube 5 is scraped off by the scraper 305, and the push plate 304 pushes the soil out of the sampling tube 5 at the same time, so that the soil collected in the sampling tube 5 can be squeezed out, thereby improving the portability during use.
