Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of environmental protection engineering, in particular to soil sampling equipment for environmental protection engineering. Background Art
[0002] A soil sampler refers to a tool used to obtain soil samples. A soil drill consists of a drill bit and a handle made of hard material (steel or hard plastic). Soil drill sampling causes little damage to the soil and soil can be sampled in layers.
[0003] Most of the existing soil samplers directly insert the drill barrel into the soil and remove it, and then take out the soil in the drill barrel to complete the soil sampling. However, when the existing soil sampler moves the drill barrel out of the soil after the soil sampling is completed, the sampled soil will slide downward under the action of its gravity trend during the removal process, which will cause the soil in the drill barrel to slide downward and be partially removed, thereby affecting the removal and preservation of the sampled soil in the drill barrel. Utility Model Content

DETAILED DESCRIPTION

However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.
[0021] A soil sampling device for environmental protection engineering, such as Figure 1-Figure 7As shown, it includes a bottom plate 1, a circular opening 2 is provided at the center of the bottom plate 1, a bracket 3 is fixedly connected to the top of the bottom plate 1 on the left side of the circular opening 2, a fixing nut 4 is embedded in the upper part of the bracket 3, a screw 5 is provided in the fixing nut 4 by threaded connection, a crank 6 and a sampling barrel 7 are respectively fixedly connected at the upper and lower ends of the screw 5, the bottom of the sampling barrel 7 is arranged as an inclined surface, four groups of arc grooves 8 are provided on the sampling barrel 7 and are distributed at equal intervals in the vertical direction, and each group of arc grooves 8 is distributed in an annular manner, a slide groove 9 connected to the arc groove 8 is provided on the inner wall of the sampling barrel 7, a concave plate 10 is slidably connected in the arc groove 8, an extrusion plate 11 slidably matched with the slide groove 9 is fixedly connected to the concave plate 10, and the concave plate 10 is connected to the inner wall of the arc groove 8 There is a first airbag 12, and the first airbags 12 distributed equidistantly in an annular manner are connected through a delivery pipe 13, and the delivery pipes 13 equidistantly distributed vertically are connected through a vertical pipe 14. A second airbag 15 is fixedly connected to the top of the sampling barrel 7. The first airbag 12 and the second airbag 15 both have a certain deformation amount and can be installed and adapted according to specific usage conditions. The second airbag 15 has an annular structure, and a disc 16 is fixedly connected to the top of the second airbag 15. A supporting spring 17 located on the inner side of the second airbag 15 is fixedly connected between the disc 16 and the sampling barrel 7. The second airbag 15 is connected to the vertical pipe 14, and the disc 16 is pressed downward to squeeze the gas in the second airbag 15 into the first airbag through the vertical pipe 14 and the delivery pipe 13. In the bag 12, the increase of gas in the first air bag 12 will push the concave plate 10 to drive the squeezing plate 11 to move, so that the squeezing plate 11 clamps the sampled soil to prevent the soil in the sampling barrel 7 from sliding down under the action of its gravity, affecting the removal and preservation of the sampled soil. The outer wall of the sampling barrel 7 is provided with symmetrically distributed fixing frames 18, and the lower parts of the two fixing frames 18 are slidably connected to the same sliding ring 19, and the upper parts of the fixing frames 18 are slidably connected to the sliding rod 20, and one end of the sliding rod 20 is fixedly connected to a wedge block 21, and a reset spring 22 is fixedly connected between the wedge block 21 and the fixing frame 18. After the disc 16 passes over the wedge block 21, the wedge block 21 is reset to the disc 16 under the action of the reset spring 22. The disk 16 moves upward to limit the position, and the side wall of the fixed frame 18 is rotatably connected to the guide wheel 23 through the support rod. The guide wheel 23 is located between the slide bar 20 and the sliding ring 19. The other end of the slide bar 20 is fixedly connected to a pull rope 24, and the pull rope 24 passes around the guide wheel 23 and is fixed to the sliding ring 19. The sliding ring 19 moves downward through the pull rope 24 to make the slide bar 20 drive the wedge block 21 to move toward the fixed frame 18, thereby releasing the limit on the upward movement of the circular disk 16. A first plug rod 25 is fixedly connected to the bottom of the bottom plate 1 outside the circular mouth 2, and second plug rods 26 connected obliquely are provided on both sides of the first plug rod 25. The first plug rod 25 and the second plug rod 26 are inserted into the soil to achieve the positioning of the bottom plate 1.
[0022] When in use, the user places the bottom plate 1 at the position where sampling is required. At this time, the first plug rod 25 and the second plug rod 26 are inserted into the soil to achieve the positioning of the bottom plate 1, and the second plug rod 26 is set at an angle to achieve the lateral stability of both sides of the first plug rod 25. Then the user rotates the screw rod 5 clockwise through the crank 6. Because the fixing nut 4 is embedded in the bracket 3, the screw rod 5 rotates and cooperates with the fixing nut 4 to move the screw rod 5 downward. The downward movement of the screw rod 5 will push the sampling barrel 7 to move downward and insert it into the soil. The continuous downward movement of the sampling barrel 7 can realize the sampling of the soil. During the sampling process, the inclined surface at the bottom of the sampling barrel 7 can pull the soil inward, making the looseness of the soil less, and ensuring that the soil will not slide down due to its own looseness. After the soil sampling is completed, the user presses the disc 16 downward to squeeze the second airbag 15, and the support spring 17 is compressed accordingly, so that the gas in the second airbag 15 enters the first airbag 12 through the vertical pipe 14 and the conveying pipe 13. The increase in the gas in the first airbag 12 will push the concave plate 10 with The squeezing plate 11 is moved to clamp the sampled soil, so as to prevent the soil in the sampling barrel 7 from sliding down under the action of its gravity, which would affect the removal and preservation of the sampled soil. In the above process, when the disc 16 moves downward to squeeze the wedge block 21, the disc 16 continues to move downward, so that the wedge block 21 is squeezed to move toward the fixing frame 18, and the return spring 22 is compressed accordingly. After the disc 16 passes over the wedge block 21, the return spring 22 resets the wedge block 21 to move the disc 16 upward. When it is necessary to release the clamping of the sampled soil, the user pulls down the sliding ring 19, and the sliding ring 19 moves downward, and through the pull rope 24, the sliding rod 20 drives the wedge block 21 to move toward the fixed frame 18, thereby releasing the limit on the upward movement of the disc 16. At this time, the disc 16 moves upward and resets under the action of the supporting spring 17. In this process, the second airbag 15 extracts the gas in the first airbag 12 through the vertical tube 14 and the conveying tube 13, so as to reset the extrusion plate 11 and release the clamping limit on the sampled soil.
