[0038] As Figure 1-10 shown, a soil detection and sampling device includes a soil-taking cylinder body 1 and a main rod 3 connected to the top end of the soil-taking cylinder body 1. A movable sliding ring 5 that can move up and down relative to the main rod 3 is sleeved on the main rod 3;

[0039] The bottom end surface of the soil-taking cylinder body 1 is arranged in an inclined plane, so that an insertion tip 17 is formed at the bottom end of the soil-taking cylinder body 1. A square soil-taking groove 13 is provided inside the soil-taking cylinder body 1, and the soil-taking groove 13 penetrates through the bottom end surface of the soil-taking cylinder body 1;

[0040] The top end of the soil-taking cylinder body 1 has a top cover plate 2. A movable top plate 22 that can move up and down is arranged in the soil-taking groove 13. The top end of the movable top plate 22 is connected with a movable rod 10 that penetrates through the top cover plate 2, and the movable rod 10 is connected to the movable sliding ring 5.

[0041] In this embodiment, the soil-taking cylinder body 1 can be cylindrical; the cross-section of the soil-taking groove 13 is square.

[0042] Preferably, a movable pedal 4 is connected to the movable sliding ring 5, and the top end of the movable rod 10 is connected to the movable pedal 4.

A flipping rod 9 is rotatably installed on the connecting piece 8. The rotation angle of the flipping rod 9 is 0° - 90°.

[0044] When this embodiment is applied, rotate the flipping rod 9 to make the included angle between it and the main rod 3 be in a 90° state, and then drive the main rod 3 to rotate by rotating the flipping rod 9. Due to the setting of the insertion tip 17, it is convenient for the soil-taking cylinder body 1 to be gradually placed into the soil during rotation. During the placement process, the soil will be divided and enter the soil-taking groove 13. After collecting the soil at a specific depth, the movable top plate 22 is located at the topmost layer of the collected soil.

[0045] Then, the soil-taking cylinder body 1 is pulled out through the flipping rod 9. When transferring the soil-taking cylinder body 1, the movable pedal 4 can be pressed down, so that the movable rod 10 drives the movable top plate 22 to move downward. In this way, all the soil in the soil-taking groove 13 can be pushed out, avoiding the residue of the topmost layer of soil in the soil-taking groove 13. Among them, through the cooperation of the movable sliding ring 5 and the main rod 3, the stability of the up-and-down movement of the movable rod 10 can be improved.

[0046] To improve the stability of the up-and-down movement of the movable top plate 22, two movable rods 10 can be provided.

[0047] Preferably, a limiting protrusion 24 for restricting the upward limit movement of the movable top plate 22 is further provided on the inner wall of the soil-taking cylinder body 1. The limiting protrusion 24 divides the soil-taking groove 13 into a linkage cavity 20 located above the movable top plate 22.

[0048] Preferably, a linkage sliding ring 25 that can move up and down relative to the main rod 3 and is located above the movable sliding ring 5 is further sleeved on the main rod 3;

[0049] Bottom sliding grooves 21 communicating with the soil-taking groove 13 are formed on both sides of the bottom end of the soil-taking cylinder body 1. The bottom sliding grooves 21 are arranged obliquely along the bottom end surface of the soil-taking cylinder body 1;

[0050] Side sliding grooves 27 are formed on the side wall of the soil-taking cylinder body 1. The top end of the side sliding groove 27 is connected and communicated with the linkage cavity 20. The bottom end of the side sliding groove 27 is connected and communicated with the top ends of the two bottom sliding grooves 21. A suitable metal sheet 14 is movably connected in the side sliding groove 27.

[0053] Preferably, a linkage pedal 23 is connected to the linkage sliding ring 25. The top end of the linkage rod 6 is connected to the linkage pedal 23.

[0054] Preferably, an arc-shaped tip 19 is provided at the bottom end of the metal sheet 14.

[0055] In this embodiment, the linkage cavity 20 is the area where the linkage slider 16 moves up and down. A through hole 28 allowing the movable rod 10 to pass through and cooperate is provided on the linkage slider 16.

[0056] When the present embodiment is in the zero position, the linkage slide block 16 should be in the high position, that is, the top end surface of the linkage slide block 16 abuts against the bottom end surface of the top cover plate 2, and accordingly, the linkage slide block 16 drives the metal sheet 14 to be stored in the side slide groove 27; the movable top plate 22 should also be in the high position, that is, the top end surface of the movable top plate 22 abuts against the bottom end surface of the limiting protrusion 24; after the soil sampling cylinder 1 is placed in the soil sampling, that is, after the soil has entered the soil sampling trough 13, the linkage pedal 23 is pressed down, so that the linkage rod 6 drives the linkage slide block 16 to move downward, and at this time, the metal sheet 14 will also move downward. Due to the guiding setting of the bottom slide groove 21, the metal sheet 14 will tilt downward along the bottom slide groove 21 during the downward movement, and use its arc-shaped tip 19 design to gradually cut the soil to achieve the effect of closing the bottom end opening of the soil sampling trough 13, so that the sampled soil can be sealed in the soil sampling trough 13. In this way, in the process of pulling out (extracting) the soil sampling cylinder 1, the soil at the bottom can be prevented from being separated from the soil sampling groove 13, thereby ensuring the integrity of the sample.

[0057] The cooperation between the linkage sliding ring 25 and the main rod 3 can improve the stability of the linkage slider 16 moving up and down. The top of the linkage slider 16 can be connected to two linkage rods 6, and the two linkage rods 6 are connected to the linkage pedal 23, which can further improve the stability of the linkage slider 16 moving up and down. Figure 8 As shown, the connection between the bottom slide groove 21 and the side slide groove 27 should be in an arc shape, so that the bottom end of the metal sheet 14 can move from the side slide groove 27 to the bottom slide groove 21.

[0058] Preferably, a vertically arranged locking groove 29 is further provided on the side wall of the soil collecting cylinder 1, the top end of the locking groove 29 passes through the top end of the top cover plate 2, and the bottom end of the locking groove 29 is located below the bottom end of the bottom chute 21;

[0059] A clearance cavity 15 is also provided on the side wall of the soil taking cylinder 1, which can be connected to the bottom end of the bottom chute 21 and communicated with the locking groove 29;

[0060] The bottom end of the metal sheet 14 is provided with a locking opening 18. When the bottom end of the metal sheet 14 slides along the side slide groove 27 and the bottom slide groove 21 and is located in the clearance cavity 15, the locking opening 18 is located in the area covered by the locking groove 29.

[0061] The locking rod 12 is also included. The bottom end of the locking rod 12 can be placed in the locking groove 29 and passes through the locking opening 18 to be located at the bottom end of the locking groove 29 .

[0062] Preferably, a handle 11 is provided at the top end of the locking rod 12 .

[0063] In this embodiment, when the metal sheet 14 closes the bottom opening of the soil sampling groove 13, the bottom end of the metal sheet 14 will be placed in the area of ​​the make way cavity 15, and the locking opening 18 will be located in the area covered by the locking groove 29. At this time, the locking rod 12 is moved down by pulling the handle 11 so that its bottom end is placed in the locking groove 29 and passes through the locking opening 18 to be located at the bottom end of the locking groove 29. In this way, the metal sheet 14 can be prevented from accidentally detaching from the soil sampling cylinder 1 after carrying the sampled soil, thereby effectively improving the reliability of operation.
