[0035] According to some embodiments of the present application, the housing 1 is in a cuboid shape, its interior is a hollow structure, and the top of the housing 1 is closed and the bottom is open. First guiding grooves 3 are formed on two opposite sides of the housing 1, and both ends of the slider 2 respectively penetrate through the two first guiding grooves 3 and extend to the outside of the housing 1. Specifically, the first guiding groove 3 penetrates through the inner and outer sides of the housing 1, the slider 2 is arranged inside the housing 1 and both ends are located in the two first guiding grooves 3. When the pushing and pulling assembly 5 pushes the slider 2 to move downward, both ends of the slider 2 slide along the first guiding groove 3, thus playing a role in limiting the movement direction of the slider 2.

[0036] According to some embodiments of the present application, the pushing and pulling assembly 5 includes a push rod 51 and a U-shaped frame 52; the bottom end of the push rod 51 penetrates through the top of the housing 1, and a sliding connection is formed between the push rod 51 and the housing 1; the U-shaped frame 52 is arranged inside the housing 1 and is fixedly connected to the bottom end of the push rod 51, and the bottom end of the U-shaped frame 52 is fixedly connected to the upper surface of the slider 2. Specifically, the U-shaped frame 52 is arranged upside down and straddles both sides of the forward and reverse motor 4. Since the push rod 51 is slidably arranged on the top of the housing 1, the push rod 51 can extend into the housing 1 under the action of an external force. In this way, the slider 3 can be driven to move downward through the push rod 51 and the U-shaped frame 52, and the forward and reverse motor 4 moves downward synchronously with the slider 2, so that the sampling cylinder 7 drills into the formation.

[0037] According to some embodiments of the present application, the push-pull assembly 5 further includes a push-pull block 53, and the push-pull block 53 is vertically and fixedly connected to the upper end of the push-pull rod 51. That is, the push-pull block 53 and the push-pull rod 51 form a T-shaped structure. By providing the push-pull block, it is convenient to apply force to the push-pull rod, making it more labor-saving to push the slider downward.

[0038] According to some embodiments of the present application, the limiting mechanism 8 includes a guiding block 81, a second guiding groove 82, and a scale line 83; the second guiding groove 82 is formed on the housing 1, and the second guiding groove 82 has the same direction as the first guiding groove 3; the guiding block 81 is slidably disposed in the second guiding groove 82, and the guiding block 81 is fixedly connected to the slider 2; the scale line 83 is sprayed on the outer surface of the housing 1. Specifically, the second guiding groove 82 is formed on the side surface of the housing 1 where the first guiding groove 3 is not provided, and the scale line 83 is located on one side of the opening of the second guiding groove 82. When the push-pull assembly 5 pushes the slider 2 downward, the guiding block 81 moves downward synchronously with the slider 2 along the second guiding groove 82. Since the scale line 83 is located at the edge of the second guiding groove 82, the descending depth of the sampling cylinder 7 can be controlled by observing the position of the guiding block 81 relative to the scale line 83 during drilling. In this solution, scale lines can also be sprayed on the outer surface of the push-pull rod 51.

[0039] According to some embodiments of the present application, the limiting mechanism 8 further includes a protruding block 84, the protruding block 84 is fixedly connected to the outer surface of the housing 1, and a positioning bolt 85 is threadedly connected to the protruding block 84. The top end of the positioning bolt 85 is located below the guiding block 81. Specifically, the protruding block 84 is located at the lower end of the second guiding groove 82, and a through threaded hole is provided on the protruding block 84 along the direction of the second guiding groove 82, and the threaded hole is adapted to the positioning bolt 85. After installation, the positioning bolt 85 is located at the middle position in the width direction of the second guiding groove 82. The protruding length of the positioning bolt 85 can be adjusted in advance before downward drilling. When the guiding block 81 moves downward and contacts the upper end of the positioning bolt 85 during drilling, the corresponding drilling depth is reached, and the control of the descending depth of the sampling cylinder 7 is more convenient.

[0040] According to some embodiments of the present application, a plurality of support mechanisms 9 are further provided on the housing 1, and the plurality of support mechanisms 9 are evenly distributed circumferentially at the lower end of the housing 1. The plurality of support mechanisms 9 are used to jointly support the housing 1 on the ground. Specifically, in this embodiment, there are four support mechanisms 9, which are respectively arranged on the four edges of the housing 1, and such an arrangement will not interfere with the limiting mechanism 8. By providing a plurality of support mechanisms 9, the housing 1 can be supported on the ground by the plurality of support mechanisms 9 during drilling and sampling.

[0041] According to some embodiments of the present application, the support mechanism 9 includes a hinge block 91 fixedly connected to the outer surface of the housing 1. A sleeve 92 is hinged to the hinge block 91, and a plug rod 93 is threadedly connected to one end of the sleeve 92 away from the hinge block 91. Since the upper end of the sleeve 92 is mounted on the hinge block 91, after the support mechanism 9 is expanded, the sleeve 92 has a certain inclination angle relative to the axis of the housing 1, thereby achieving a stable support effect on the housing 1.

[0042] According to some embodiments of the present application, a bolt head 94 is fixedly provided on the outer surface of the plug rod 93, and the end of the plug rod 93 away from the sleeve 92 is a tip. Specifically, the bolt head 94 can be a hexagonal structure or a flat position provided on the outer surface of the plug rod 93, and the bolt head 94 and the plug rod 93 are an integral structure. Before sampling the soil layer, the protruding length of the plug rod 93 from the sleeve 92 can be adjusted through the bolt head 94, and then the tip of the plug rod 93 is inserted into the formation to support and fix the housing 1.

[0043] According to some embodiments of the present application, a material taking port 10 is provided on the housing 1, and the material taking port 10 is adapted to the sampling cylinder 7. A plurality of tooth grooves are provided at the bottom end of the sampling cylinder 7. Specifically, the material taking port 10 is provided on the side surface of the housing 1 where the first guiding groove 3 and the second guiding groove 82 are not provided. Tooth grooves are provided at the bottom end of the sampling cylinder 7. When the forward and reverse motor 4 drives the sampling cylinder 7 to rotate, the tooth grooves at the bottom end of the sampling cylinder 7 have better crushing ability, so that the sampling cylinder 7 can drill into the formation. The coupling 6 and the sampling cylinder 7 are connected by bolts, which facilitates the disassembly and assembly of the coupling 6 and the sampling cylinder 7. By driving the coupling 6 to rotate through the output rotating shaft of the forward and reverse motor 4, the sampling cylinder 7 can drill holes in the ground through the tooth grooves, and the slider 2 can be pushed downward by the pushing and pulling assembly 5, so that the sampling cylinder 7 can be inserted into the ground for sampling, and the maximum descending height of the sampling cylinder 7 can be controlled by the limiting mechanism 8, achieving the effect of accurate sampling.

[0044] Working principle of the sampling device in the embodiments of the present application: Before sampling, the protruding length of the insertion rod 93 from the sleeve 92 can be adjusted through the bolt head 94, and the tip of the insertion rod 93 is inserted into the formation, which can support and fix the housing 1. According to the depth of the sample to be taken, the positioning bolt 85 is rotated, so that the length of the positioning bolt 85 above the protruding block 84 can be adjusted. When sampling, first start the forward and reverse motor 4, so that the output rotating shaft of the forward and reverse motor 4 drives the coupling 6 to rotate, and the coupling 6 drives the sampling cylinder 7 to rotate, so that the sampling cylinder 7 drills holes in the ground through the tooth grooves, and applies a downward force to the push-pull rod 51 through the push-pull block 53, which can make the U-shaped frame 52 push the slider 2 to slide inside the first guide groove 3, so that the sampling cylinder 7 can be inserted into the ground for sampling. At the same time, the guide block 81 follows the slider 2 to slide in the second guide groove 82. When the guide block 81 contacts the positioning bolt 85, it is the required sampling depth, and accurate sampling can be carried out according to the required depth, effectively ensuring the accuracy of the soil layer sample.
