[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] refer to Figures 1 to 4 This utility model provides a portable intelligent sampling device for deep soil environment, comprising: a sampling tube 16, multiple connecting tubes 15, and a driving cylinder 11. The sampling tube 16 and the connecting tubes 15 have the same inner and outer diameter. A fixing cylinder 26 is installed on the top of the sampling tube 16, and the inner surface of the fixing cylinder 26 is flush with the inner surface of the sampling tube 16. A lower connecting cylinder 25 is connected to the lower end of the inner surface of the connecting tube 15, and the outer surface of the lower connecting cylinder 25 is flush with the outer surface of the connecting tube 15. The inner surface of the lower connecting cylinder 25 is threadedly connected to the outer surface of the fixing cylinder 26. An upper connecting cylinder 24 is connected to the top of the connecting cylinder, and the size and structure of the upper connecting cylinder 24 are the same as those of the fixing cylinder 26. The top of the connecting tube 15 or the sampling tube 16 is movably connected to the bottom of the driving cylinder 11. The outer surface of the connecting tube 15 or the sampling tube 16 is threadedly connected to the lower end of the inner surface of the outer connecting cylinder 14, and the outer surface of the driving cylinder 11 is threadedly connected to the upper end of the inner surface of the outer connecting cylinder 14. The top of the connecting pipe 15 is fixedly connected to the drive end of the rotary motor 12. The fixed end of the rotary motor 12 is connected to the lifting plate 1. The two ends of the lifting plate 1 are movably connected to the first mounting plate 4 and the second mounting plate, respectively. The first mounting plate 4 is slidably connected to the first electric slide rail 2 through the first slider 3. The second mounting plate is slidably connected to the guide rail 7 through the second slider 8. The bottoms of the electric slide rail 2 and the guide rail 7 are movably connected to the tops of the first base 5 and the second base 9, respectively. A displacement sensor 13 is installed on the top of the lifting plate 1.

[0016] It should be noted that by setting up a sampling tube 16 with a fixed cylinder 26 and multiple connecting tubes 15, during use, the sampling tube 16 and the connecting tubes 15 can be connected to each other by threaded connection according to different depths, so as to achieve different lengths to suit different sampling depths. Furthermore, by setting up a lifting plate 1 that is movably connected to the first mounting plate 4 and the second mounting plate, an electric slide rail 2 that is movably connected to the first base 5, and a guide rail 7 that is movably connected to the second base 9, the mechanisms can be disassembled when being carried and reassembled after arriving at the destination. By making the device an assemblable structure, it is convenient for personnel to carry.

[0017] In practical use, firstly, connect the two ends of the lifting plate 1 to the lowering plate, the first mounting plate 4, and the second mounting plate. Connect the electric slide rail 2 to the first base 5 and the guide rail 7 to the second base 9. Place the first base 5 and the second base 9 on the ground to be sampled. Then, as needed, take out a certain number of connecting tubes 15 and connect the sampling tube 16 to the connecting tubes 15. Driven by the rotary motor 12, rotate the sampling tube 16. Simultaneously, driven by the electric slide rail 2, move the sampling tube 16 downwards, thus inserting it into the soil for sampling. Once most of the sampling tube 16 has entered the soil, rotation stops. Then, the outer connecting cylinder 14 is manually rotated upwards to separate it from the fixed cylinder 26. Next, the upward movement of the electric slide rail 2 moves the sampling tube upwards, separating it from the fixed cylinder. The bottom of the connecting tube 15 is then connected to the top of the sampling tube, and the upper end of the connecting tube 15 is connected to the drive cylinder 11 via the outer connecting cylinder 14. The machine casing, driven by the rotation of the rotary motor 12 and the electric slide rail 2, moves the sampling tube 16 further downwards into the deeper soil. Once the sampling depth is reached... The soil sample enters the sampling tube. Then, the upward movement of the rotary electric slide rail 2 continuously moves the connecting tube 15 and the sampling tube 16 upwards. During this movement, when the connection point between connecting tubes 15 and 16, or between connecting tube 15 and sampling tube 16, is above the ground, the uppermost connecting tube 15 is detached. If the remaining connecting tubes 15 connected to the sampling tube 16 are few in number and light in weight, they can be manually removed by holding the remaining uppermost connecting tube and manually connecting tube 15 to sampling tube 16. If they are heavy, the remaining uppermost connecting tubes are removed using the outer connecting tube 14. Connected to the drive cylinder 11, the connecting tube 15 and the sampling tube 16 continue to move upward via the electric slide rail 2 until the sampling tube 16 is removed from the soil. The sample is then taken out from the bottom of the sampling tube 16, thus completing the sampling operation. During the downward movement of the sampling tube 16 via the electric slide rail 2, the displacement sensor 13 records the downward movement distance of the electric slide rail 2. The processor adds up the downward movement distances to obtain the depth of the sampling tube 16. Through the displacement sensor 13, the device can accurately determine the sampling depth, thus intelligently controlling the sampling depth.

[0018] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3As shown, the first mounting plate 4 and the second mounting plate are respectively provided with a plurality of first external screw holes 32 and second external screw holes 22 on their sides. The two ends of the lifting plate 1 are respectively connected to the first connecting plate 19 and the second connecting plate 21. The side of the first connecting plate 19 is provided with a first internal screw hole 20 that mates with the first external screw hole 32. The second connecting plate 21 is provided with a second internal screw hole 33 that mates with the second external screw hole 22.

[0019] It should be noted that by setting the first external threaded hole 32 and the first internal threaded hole 20, and the second external threaded hole 22 and the second internal threaded hole 33, they can be connected by bolts to achieve a tight connection between the first mounting plate 4, the second mounting plate and the lifting plate 1 at both ends, thereby improving the stability and convenience of the connection.

[0020] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3 , Figure 4 As shown, the bottom of the electric slide rail 2 and the guide rail 7 are respectively connected to the first mounting groove 38 and the second mounting groove 39. The first mounting groove 38 and the second mounting groove 39 are respectively slidably connected to the first mounting block 27 and the second mounting block 28. The first mounting block 27 and the second mounting block 28 are respectively disposed on the top of the first base 5 and the second base 9.

The second mounting block 28 is provided with a second connecting groove 29 that matches the second mounting hole 23 on its side.

[0022] It should be noted that by setting the first mounting slot 38 and the first mounting block 27, and the second mounting slot 39 and the second mounting block 28, it is convenient to connect the electric slide rail 2 and the first base 5, and the guide rail 7 and the second base 9 to each other. The first mounting hole 34 and the first connecting slot 35, and the second mounting hole 23 and the second connecting slot 29 can be connected by corresponding bolts to improve the stability of the connection.

[0023] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3 As shown, the top of the lifting plate 1 is provided with a first limiting hole 30 and a second limiting hole 36 at both ends.
