[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides as Figures 1-4A soil pollution sampling device shown in the figure includes a fixed bottom plate 1. A ball screw 2 is rotatably connected to the fixed bottom plate 1. The ball screw 2 is connected to a lifting plate 3 through a ball nut. A U-shaped base 4 is installed on the top outer wall of the lifting plate 3. Support guide rods 5 are respectively slidably clamped on the U-shaped base 4. The number of the support guide rods 5 is four, and they are symmetrically arranged in pairs on the U-shaped base 4. One end of the support guide rod 5 is installed with a sampling plate 6. One sampling plate 6 is installed at one end of every two support guide rods 5. An electric push rod 7 is installed on the top outer wall of the U-shaped base 4. A push ring 8 is connected to the output end of the electric push rod 7. A scraping ring 10 is slidably clamped on the sampling plate 6. An inner push plate 11 is installed on the inner wall of the scraping ring 10. The inner push plate 11 is slidably clamped with the sampling plate 6. L-shaped side plates 12 are respectively installed on the side wall of the scraping ring 10. Guide sleeves 13 are respectively installed on the top outer wall of the lifting plate 3. A tightening screw is connected to the guide sleeve 13. The L-shaped side plate 12 is clamped with the guide sleeve 13, and then the tightening screw is tightened so that it abuts against the L-shaped side plate 12, thereby fixing the scraping ring 10. When sampling is required, first, the lifting plate 3 is driven to move downward by the ball screw 2 so that the sampling plate 6 can be inserted into the soil. Then, the push ring 8 is driven to descend by the electric push rod 7. The two sampling plates 6 are simultaneously squeezed by the push ring 8, so that the two sampling plates 6 tend to approach each other, thereby enabling the two sampling plates 6 to press the soil inside them, which is beneficial to preventing the soil from falling when the sampling plate 6 moves upward. After the sampling plate 6 is removed, the tightening screw on the guide sleeve 13 can be loosened, and then the L-shaped side plate 12 can be pulled downward. The inner push plate 11 can effectively push the soil inside the sampling plate 6 to move, thereby pushing out the soil inside the sampling plate 6. Moreover, the scraping ring 10 can also scrape off the soil on the outer wall of the sampling plate 6, thereby being able to clean the outer wall of the sampling plate 6, which is beneficial to avoiding the soil on it from polluting the storage box when the device is stored later.

[0024] In this embodiment, a support spring 9 is arranged on the side wall of the support guide rod 5. The support spring 9 is arranged outside the U-shaped base 4. The support spring 9 can drive the sampling plate 6 to cling to the lifting plate 3, so that there is a space for the two sampling plates 6 to approach each other subsequently.

[0025] In this embodiment, support vertical rods 14 are respectively installed on the outer wall of the top of the fixed bottom plate 1. The support vertical rods 14 are slidably clamped with the lifting plate 3, so as to be able to guide and support the lifting plate 3, which is beneficial to improving the stability of the lifting plate 3 when moving up and down. One end of the support vertical rod 14 is installed with a fixed top plate 15. The end of the ball screw 2 far from the fixed bottom plate 1 is rotatably connected to the fixed top plate 15. By rotatably connecting the ball screw 2 with the fixed top plate 15, it is beneficial to improve the smoothness of the rotation of the ball screw 2. A driving motor 16 is installed on one side wall of the fixed top plate 15. The output end of the driving motor 16 is connected with a driving pulley 17. One end of the ball screw 2 is installed with a driven pulley 18. The driving pulley 17 is connected with the driven pulley 18 through a transmission belt. By driving the driving pulley 17 at the output end of the driving motor 16 to rotate, the driven pulley 18 can drive the ball screw 2 to rotate, so that the ball screw 2 can drive the lifting plate 3 to move up and down.

[0026] In this embodiment, fixed side plates 19 are respectively installed on the outer wall of the top of the fixed bottom plate 1. Through the fixed side plates 19, it is beneficial to conveniently lift the sampling device, so as to conveniently move the sampling device.

[0027] The working principle of this utility model: This utility model is a soil pollution sampling device. By rotating the ball screw 2, the lifting plate 3 can move downward, so that the sampling plate 6 can be inserted into the soil. Then, the electric push rod 7 drives the push ring 8 to descend, so that it can simultaneously squeeze the sampling plate 6, so that the two sampling plates 6 tend to approach each other, and then the soil inside the two sampling plates 6 can be clamped, which is beneficial to avoiding the soil inside the sampling plate 6 from falling when the sampling plate 6 moves upward;

[0028] After the sampling plate 6 is removed, by loosening the tightening screw on the guide sleeve 13 and then pulling the L-shaped side plate 12 downward, the inner push plate 11 can push the soil inside the sampling plate 6 to move, and at the same time, the scraping ring 10 can scrape off the soil on the outer wall of the sampling plate 6, which is beneficial to avoiding the soil on the device from polluting the storage box.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
