Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As Figure 1 - Figure 4As shown in the figure, a surface impurity removal device for soil sampling includes a mounting bracket 1 and a steering component and a rotating component arranged on the mounting bracket 1. The steering component includes a slide rail cavity 2, a connecting shaft 201, an adjusting plate 202, a first rotating shaft 203, an electric push rod 204, a support leg 205, a connecting block 206 and a second rotating shaft 207. Both sides of the inner wall of the mounting bracket 1 are fixedly connected with a slide rail cavity 2. A connecting shaft 201 is arranged at the lower end of the slide rail cavity 2. The outer surface of the connecting shaft 201 is connected with an adjusting plate 202. A first rotating shaft 203 is arranged on the front end face of the adjusting plate 202. An electric push rod 204 is arranged on the outer surface of the first rotating shaft 203. Four ends of the lower end face of the mounting bracket 1 are provided with support legs 205. A connecting block 206 is arranged on the side wall of the support leg 205. A second rotating shaft 207 is arranged on the front end face of the connecting block 206. The end of the electric push rod 204 is rotatably connected with the second rotating shaft 207. The rotating component includes a support shaft 3, a support slide rail 301, a threaded rod 302, a slider 303, a connecting groove 304, a support plate 305, a shock absorption spring 306, a damping support rod 307, a mounting block 308 and a scraper 309. A support shaft 3 is arranged on the upper end face of the adjusting plate 202. A support slide rail 301 is arranged at the top of the support shaft 3. A threaded rod 302 is rotatably connected to the inner wall of the support slide rail 301. A slider 303 is mounted on the outer surface of the threaded rod 302. A connecting groove 304 is formed on the upper end face of the slider 303. A support plate 305 is connected inside the connecting groove 304. A shock absorption spring 306 is mounted on the inner wall of the support plate 305. A damping support rod 307 is arranged on the inner ring of the shock absorption spring 306 on the inner wall of the support plate 305. The end of the shock absorption spring 306 is mounted with a mounting block 308. A scraper 309 is fixedly connected to the front end face of the mounting block 308. When the electric push rod 204 arranged is telescoped, the adjusting plate 202 arranged is rotatably connected with the telescopic end of the electric push rod 204 through the first rotating shaft 203. Then the end of the electric push rod 204 is rotatably connected to the connecting block 206 through the second rotating shaft 207, realizing that the adjusting plate 202 is rotatably connected to the lower end of the slide rail cavity 2 through the connecting shaft 201, so that the scraper 309 is moved below the sampling shaft 507. When the sampling shaft 507 moves downward, it is convenient to scrape the soil on the inner and outer walls of the sampling shaft 507. Then when the device is performing sampling work, the adjusting plate 202 is moved to the side wall of the support leg 205 through the electric push rod 204, which does not affect the sampling work. The flexible operation method enables the device to adapt to different working environments and sampling requirements. When cleaning the soil, first move the sampling shaft 507 to the top, and then move the scraper 309 below the sampling shaft 507. The support shaft 3 arranged is driven by a motor, and then the support slide rail 301 is rotated to perform impurity removal work on the inner and outer walls of the sampling shaft 507 with the two scrapers 309 respectively, improving the accuracy and efficiency of the impurity removal work. And when the threaded rod 302 is rotated on the inner wall of the support slide rail 301,The distance between the support plate 305 and the scraping blade 309 mounted on the slider 303 is adjusted, enabling the scraping blade 309 to adapt to sampling shafts 507 of different diameters, enhancing the versatility and flexibility of the device. Meanwhile, the distance adjustment can also ensure a tight fit between the scraping blade 309 and the sampling shaft 507, further improving the impurity removal effect. Moreover, the support plate 305 is positioned on the upper end face of the slider 303 through the connecting groove 304 and locked and disassembled by threaded bolts, so that the scraping blade 309 can be replaced, facilitating the selection of a suitable scraping blade 309 for use. Then, the scraping blade 309 is mounted on the mounting block 308 and performs shock absorption and buffering on the inner wall of the support plate 305 along the shock absorption spring 306 and the damping strut 307. During the process of scraping soil by the scraping blade 309, vibrations and impacts may occur due to contact with the sampling shaft 507. The shock absorption spring 306 and the damping strut 307 can effectively absorb and disperse these forces, reducing damage to the device and the scraping blade 309 itself caused by vibrations and extending its service life.

[0025] Furthermore, a limiting plate 4 is fixedly connected to the rear side wall of the slide rail cavity 2. The provided limiting plate 4 is used to control the steering angle of the adjusting plate 202 under the rotational connection of the connecting shaft 201 by the electric push rod 204. When the adjusting plate 202 is in contact with the front end face of the limiting plate 4, the rotation angle of the adjusting plate 202 is 90°, which is exactly corresponding to the position below the sampling shaft 507.

[0026] Furthermore, the support plate 305 is snap-fitted with the slider 303 through the connecting groove 304. The support plate 305 and the slider 303 are locked by bolts. The support plate 305 is positioned on the upper end face of the slider 303 through the connecting groove 304 and locked and disassembled by threaded bolts, so that the scraping blade 309 can be replaced, facilitating the selection of a suitable scraping blade 309 for use.

[0027] Furthermore, a cavity is formed inside the front end face of the support plate 305. The shock absorption springs 306 are evenly distributed along the cavity inside the support plate 305. The provided mounting block 308 performs shock absorption inside the cavity of the support plate 305 through the shock absorption springs 306, improving the stability during the compression operation.

[0028] Embodiment 2

[0029] Such as Figure 1 and Figure 4As shown in the figure, a surface impurity removal device for soil sampling proposed by the present utility model. Compared with Embodiment 1, as another implementation manner of the present utility model, a top frame 5 is fixedly connected to the top end of the slide rail cavity 2. A hydraulic rod 501 is arranged at the center of the top frame 5. The telescopic end of the hydraulic rod 501 is fixedly connected to a mounting plate 502, and both ends of the mounting plate 502 are slidably connected to the inner wall of the slide rail cavity 2. The arranged hydraulic rod 501 slides the mounting plate 502 along the inner wall of the slide rail cavity 2, improving the stability during the lifting and sampling work.

[0030] Furthermore, a mounting seat 503 is arranged at the lower end of the mounting plate 502, and a driving rod 504 is arranged on the lower end surface of the mounting seat 503. A motor is arranged inside the mounting seat 503 to rotate the driving rod 504, thereby rotating the sampling shaft 507. When moving downward through the hydraulic rod 501, the sampling shaft 507 contacts the soil, and the cavity inside the sampling shaft 507 contacts the soil for sampling.

[0031] Furthermore, a first fitting plate 505 is fixedly connected to the lower end of the driving rod 504, a second fitting plate 506 is attached to the lower end surface of the first fitting plate 505, the first fitting plate 505 and the second fitting plate 506 are connected by bolts, and a sampling shaft 507 is fixedly connected to the lower end of the second fitting plate 506. The arranged sampling shaft 507 is attached to the first fitting plate 505 through the second fitting plate 506. Rotating the bolt realizes the disassembly and replacement of the sampling shaft 507, enabling selection when sampling different soils.

[0032] Working principle: When the electric push rod 204 is telescoped, the set adjusting plate 202 is rotationally connected to the telescopic end of the electric push rod 204 through the first rotating shaft 203. Then, the end of the electric push rod 204 is rotationally connected to the connecting block 206 through the second rotating shaft 207, so that the adjusting plate 202 is rotationally connected to the lower end of the slide rail cavity 2 through the connecting shaft 201, thereby moving the scraper 309 below the sampling shaft 507. When the sampling shaft 507 moves downward, the sampling shaft 507 contacts the scraper 309, facilitating the scraping of soil from the inner and outer walls of the sampling shaft 507. Then, when the device is performing sampling work, the adjusting plate 202 is moved to the side wall of the support leg 205 through the electric push rod 204, without affecting the sampling work. The flexible operation mode enables the device to adapt to different working environments and sampling requirements. When cleaning the soil, first move the sampling shaft 507 to the top, and then move the scraper 309 below the sampling shaft 507. The set support shaft 3 is driven by a motor, and then the support slide rail 301 is rotated, and the two scrapers 309 are respectively used for impurity removal on the inner and outer walls of the sampling shaft 507, improving the accuracy and efficiency of the impurity removal work. When rotating the threaded rod 302 on the inner wall of the support slide rail 301, the distance between the support plate 305 and the scraper 309 installed on the slider 303 is adjusted, enabling the scraper 309 to adapt to sampling shafts 507 of different diameters, increasing the versatility and flexibility of the device. At the same time, the distance adjustment can also ensure the close fit between the scraper 309 and the sampling shaft 507, further improving the impurity removal effect. Moreover, the support plate 305 is positioned on the upper end surface of the slider 303 through the connecting groove 304 and locked and disassembled through threaded bolts, so that the scraper 309 can be replaced, facilitating the selection of a suitable scraper 309 for use. Then, the scraper 309 is installed on the inner wall of the support plate 305 along the shock absorption spring 306 and the damping support rod 307 through the mounting block 308 for shock absorption and buffering. During the process of the scraper 309 scraping soil, vibrations and impacts may occur due to contact with the sampling shaft 507. The shock absorption spring 306 and the damping support rod 307 can effectively absorb and disperse these forces, reducing damage to the device and the scraper 309 itself caused by vibrations and extending its service life.

[0033] This is the working principle of the surface impurity removal device for soil sampling.
