[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application discloses a soil sampling device for land reclamation. Figure 1 、 Figure 2 、 Figure 3, including a plate-shaped support plate 1, and a plurality of conical limiting rods 2 are fixedly connected to the lower surface of the support plate 1, and a circular plate-shaped limiting plate 3 is fixedly connected to the outer surface of the plurality of limiting rods 2, so that when soil sampling is required, the plurality of limiting rods 2 are inserted into the soil so that the plurality of limiting plates 3 are located on the upper surface of the soil, thereby stably fixing the device, thereby ensuring that the subsequent drilling tube 5 can be vertically inserted into the soil to avoid skewing, and an annular support ring 4 is fixedly connected to the upper surface of the support plate 1, The inner wall of the support ring 4 is slidably connected to the drilling tube 5, and a columnar first handle 11 is fixedly connected to the outer surface of the drilling tube 5, so that the staff can rotate the first handle 11 by hand to rotate the drilling tube 5, thereby rotating the drilling tube 5 into the soil, and a plurality of square groove-shaped sampling grooves 6 are opened on the side surface of the drilling tube 5, and a plurality of round box-shaped containing boxes 7 are slidably connected to the inner wall of the drilling tube 5, so that the containing boxes 7 can slide to cover the sampling grooves 6, thereby ensuring that the sampling grooves 6 can be covered when the drilling tube is inserted into the soil and when it is pulled out of the soil. To prevent soil from entering the drilling tube 5 from the sampling groove 6, which affects the accuracy of soil sampling, a cylindrical rotating shaft 8 is rotatably connected to the inner wall of the support plate 1. The upper end of the rotating shaft 8 passes through the drilling tube 5 to the top thereof, and the upper end of the rotating shaft 8 is fixedly connected to a cylindrical second handle 12. The outer surface of the rotating shaft 8 is fixedly connected to a plurality of cylindrical connecting columns 9, and the rotating shaft 8 is located at a third of the connecting column 9. The rotating shaft 8 is fixedly connected to a plurality of arc-shaped sheet-like sampling pieces 10 through the plurality of connecting columns 9, so that the staff can rotate the second handle 12 to The hand 12 drives the rotating shaft 8 to rotate, thereby driving several connecting columns 9 and several sampling pieces 10 to rotate. Since the rotating shaft 8 is located at one-third of the connecting column 9, during the rotation process, the sampling pieces 10 can enter the outside of the drilling tube 5 through the sampling groove 6, thereby scraping the soil through the distal side of the several sampling pieces 10 to sample the soil, scraping the soil into the drilling tube 5, and then falling into the container box 7 below for collection, so that multi-layer sampling can be performed on each layer of the soil, greatly improving the sampling efficiency.

[0022] Reference Figure 2 The side surfaces of several containing boxes 7 are fixedly connected with arc-shaped connecting plates 13, and the upper surface of the drilling tube 5 is provided with an arc-shaped chute 14, and the connecting plates 13 and the inner wall of the chute 14 slide relative to each other, so that the staff can move the connecting plates 13 up and down to change the position of the containing boxes 7, so that when the drilling tube 5 is inserted into the soil and pulled out of the soil, the containing boxes 7 can be moved to block the sampling groove 6, thereby preventing soil from entering the drilling tube 5. When sampling the soil, the containing box 7 can be moved to the bottom of the sampling groove 6 so that the sampling piece 10 can scrape the soil into the inside of the containing box 7 for collection for subsequent soil testing.

[0023] Reference Figure 2 、 Figure 4 A first limiting hole 15 and a second limiting hole 16 are provided on the side surface of the connecting plate 13, and a groove-shaped limiting groove 17 is provided on the outer surface of the first handle 11. The inner wall of the limiting groove 17 is elastically and slidably connected with a block-shaped limiting block 18 through a spring, and the limiting block 18 can be engaged with the inner wall of the first limiting hole 15 or the second limiting hole 16, so as to press the limiting block 18 to move it away from the inner wall of the second limiting hole 16, and then move the connecting plate 13 downward. After the external force disappears, the limiting block 18 rebounds and engages with the inner wall of the first limiting hole 15 under the resetting action of the spring, thereby stably fixing the connecting plate 13 and the several containing boxes 7 to ensure smooth soil sampling.

[0024] The implementation principle of a soil sampling device for land reclamation in the embodiment of the present application is as follows: the device is placed on the soil to be tested, and then the staff inserts several limit rods 2 into the soil so that several limit plates 3 are close to the upper surface of the soil, thereby stably fixing the device to ensure that the subsequent drilling tube 5 can be vertically inserted into the soil, and then the staff holds the first handle 11 and rotates the drilling tube 5 downward into the soil. After reaching a certain depth, the limit block 18 is pressed to make it away from the inner wall of the second limit hole 16, and then the connecting plate 13 is moved downward. After the external force disappears, the limit block 18 rebounds and engages with the inner wall of the first limit hole 15 under the return action of the spring, thereby stably fixing the connecting plate 13 and several containing boxes 7, so that the several containing boxes 7 are stably located below the several sampling grooves 6, and then the staff rotates the second handle 12 to drive the rotating shaft 8 to rotate, thereby driving the several connecting columns 9 and the several sampling pieces 10 to rotate. Since the rotating shaft 8 is located at one-third of the connecting column 9, the sampling piece 10 can enter the soil outside the drilling tube 5 through the sampling groove 6 during the rotation, so that the soil is scraped and sampled through the distal side of several sampling pieces 10, and the soil is scraped from the sampling groove 6 into the drilling tube 5, and then falls to the containing box 7 below for collection, so that multi-layer sampling can be performed on each layer of the soil, which greatly improves the sampling efficiency. After the sampling is completed, the limit block 18 is pressed to make it distal. From the inner wall of the first limiting hole 15, the connecting plate 13 is then moved upward. Then, after the external force disappears, the limiting block 18 rebounds and engages with the inner wall of the second limiting hole 16 under the restoring action of the spring, thereby stably fixing the multiple containing boxes 7, so that the multiple containing boxes 7 can cover the multiple sampling slots 6, so that when the drilling tube 5 is pulled out of the soil, the soil can be prevented from entering the drilling tube 5 from the sampling slots 6, thereby preventing the mixing of soil at different layers and ensuring the accuracy of subsequent soil detection.
