[0017] 1. When sampling, the present invention can drill soil samples from underground and temporarily store them in the sampling cylinder. After reaching the sampling depth, the device can be controlled to store the samples in the collection boxes corresponding to the depths respectively. At the same time, the lower ends of the collection boxes can be closed to avoid the mixing of samples with each other, and also avoid the compression of samples due to extrusion when the device is pulled out.

Through the coordinated action of the air chamber, the limiting plate and the threaded clamp, the fixed state of the sampling cylinder is dynamically adjusted during the sampling process. When the sampling cylinder penetrates into the soil, the air pressure change drives the limiting plate to disengage from the card slot, allowing the sampling cylinder to move downward; at the same time, the threaded clamp meshes with the sampling cylinder thread through elastic pressure, preventing the sampling cylinder from tilting or detaching, ensuring the verticality and stability of the drilling process, and reducing the need for manual intervention.

[0019] 3. Through the integrated mechanical transmission and pneumatic control system of the present invention, users only need to perform simple rotation and pressing operations to complete the collection and isolation of soil at different depths, reducing the steps of frequently replacing containers or manually stratifying in the traditional sampling process, significantly improving the sampling efficiency, and at the same time reducing the operation complexity.

Four sealing grooves 410 and power chambers 402 are evenly distributed in a circular shape in the collection box 401;

[0029] The specific operation is as follows. When sampling, the soil sample can be drilled from the ground and temporarily stored in the sampling cylinder 12. After reaching the sampling depth, the device can be controlled to store the samples in the collection boxes 401 at the corresponding depths respectively. At the same time, the lower end of the collection box 401 can be sealed to avoid mixing of samples with each other, and to avoid compression of the samples due to extrusion when the device is withdrawn. When taking out the collection box 401, it can also prevent the samples from leaking out of the collection box 401, ensuring the original state of the samples after sampling and improving the detection accuracy.

[0030] Please refer to Figure 1 and Figures 4 to 6 As shown in the figure, one side of the cylinder body 1 is connected with a soil-breaking plate 5, and a sliding cavity 6 is opened in the cylinder body 1. The other side of the cylinder body 1 is connected with a support spring 7, and the other end of the support spring 7 is connected with a rotating plate 8. An air cavity 9 is opened on one side of the sliding cavity 6, and a plug plate 10 is slidably connected in the air cavity 9. One side of the plug plate 10 is connected with a sliding rod 11. The rotating plate 8 is elastically connected to the cylinder body 1 through the support spring 7, and the other end of the sliding rod 11 is connected with the rotating plate 8. The sliding rod 11 is in sliding fit with the cylinder body 1 through the sliding cavity 6. A sampling cylinder 12 is slidably connected in the through groove 2, and a soil-drilling plate 13 is connected to one end of the sampling cylinder 12. Thread grooves 14 are symmetrically opened on the surface of the sampling cylinder 12, and the side wall of the sampling cylinder 12 is provided with threads. The sealing plate 413 is snap-fitted with the sampling cylinder 12 through the thread grooves 14. Connecting grooves 15 are symmetrically opened on the inner side of the air cavity 9, and a limiting cavity 16 is connected to one side of the connecting groove 15.

A connecting cavity 19 is provided on the other side of the connecting groove 15, and connecting springs 20 are symmetrically connected in the connecting cavity 19. The other end of the connecting spring 20 is connected with a thread clamp 21. The limiting plate 18 is in snap-fitting and sliding connection with the sampling cylinder 12 through the thread grooves 14, and the limiting plate 18 is elastically connected to the limiting cavity 16 through the limiting spring. The thread clamp 21 is in threaded connection with the sampling cylinder 12, and the thread clamp 21 is elastically connected to the connecting cavity 19 through the connecting spring 20.

[0031] In some specific embodiments, the above-mentioned soil-breaking plate 5 and soil-drilling plate 13 are both spiral.

[0032] During use, the device is adjusted according to the sampling situation, so as to smoothly complete sampling and sample storage, and avoid sample mixing due to force during sampling. Moreover, during the sampling process, the sampling cylinder 12 can be kept stable to prevent the sampling cylinder 12 from detaching or tilting. Through the coordinated action of the air chamber 9, the limiting plate 18 and the threaded clamp 21, the fixed state of the sampling cylinder 12 is dynamically adjusted during the sampling process. When the sampling cylinder 12 penetrates into the soil, the air pressure change drives the limiting plate 18 to disengage from the clamping groove 14, allowing the sampling cylinder 12 to move downward; at the same time, the threaded clamp 21 is threadedly engaged with the sampling cylinder 12 through elastic pressure to prevent the sampling cylinder 12 from tilting or detaching, ensuring the perpendicularity and stability of the drilling process, reducing the need for manual intervention. During use, through the integrated mechanical transmission and pneumatic control system, users only need to perform simple rotation and pressing operations to complete the collection and isolation of soil at different depths, reducing the steps of frequently replacing containers or manually layering during the traditional sampling process, significantly improving the sampling efficiency, and at the same time reducing the operation complexity.

[0033] When using the crop soil sample collector of the present invention, first place the collection box 401 into the placement groove 3, and then insert the sampling cylinder 12 into the through groove 2. At this time, the sampling cylinder 12 penetrates from the lower end of the collection box 401, pushing the partition 404 to rotate in the power chamber 402 and driving the rack 405 to move. The rack 405 drives the rack 405 to rotate through the gear set 406, and then can push the air plate 408 to slide in the power chamber 402. The slider 409 and the chute 403 limit the air plate 408 to prevent the air plate 408 from tilting during movement. The air in the power chamber 402 is squeezed into the sealing groove 410 by the air plate 408 through the ventilation groove 411, driving the sealing plate 413 to move in the sealing groove 410 and snap into the clamping groove 14. The different-sized gears on the gear set 406 can amplify the stroke of the rack 405 driving the air plate 408 to move, so as to press more air into the sealing groove 410. As the air plate 408 continues to move, the air is compressed in the power chamber 402. After the sampling cylinder 12 is completely inserted, place the device at the sampling point;

[0034] Then rotate the rotating plate 8. The rotating plate 8 can drive the barrel body 1 to rotate through the sliding rod 11, and then drive the sampling cylinder 12 to rotate synchronously through the limiting plate 18, so that the soil drilling plate 13 drills into the ground and sends the soil into the sampling cylinder 12 for temporary storage. During the process of the barrel body 1 driving the sampling cylinder 12 to drill into the ground, the barrel body 1 can drill into the ground together with the soil breaking plate 5 until the predetermined sampling depth is reached. At this time, press the rotating plate 8 downward on the barrel body 1, and drive the plug plate 10 to descend in the air chamber 9 through the sliding rod 11. The chute 403 can limit the sliding rod 11, so as to ensure that the plug plate 10 will not tilt during movement;

[0035] The air in the air chamber 9 is pressed into the connection chamber 19, and at the same time, the air in the restriction chamber 16 is pumped into the air chamber 9, so that the air pressures in the connection chamber 19 and the restriction chamber 16 change, thereby driving the restriction plate 18 and the threaded clamp 21 to move in the restriction chamber 16 respectively. The restriction plate 18 is withdrawn from the card slot 14 and compresses the restriction spring 17, while the threaded clamp 21 is pressed against the sampling cylinder 12 and stretches the connection spring 20. At this time, when the rotating plate 8 is rotated again, the barrel body 1 can be rotated, and through the threaded connection between the threaded clamp 21 and the sampling cylinder 12, the sampling cylinder 12 is continuously pushed downward. As the sampling cylinder 12 moves downward in the through slot 2, the soil sample temporarily stored in the sampling cylinder 12 will enter the collection box 401 as the subsequent soil enters. As the soil sample enters the collection box 401, the soil sample can continue to exert pressure on the partition 404, and the partition 404 can prevent the soil from entering the power chamber 402. After the sampling cylinder 12 is detached from the lower end of the collection box 401, the compressed air in the power chamber 402 can quickly squeeze into the sealing groove 410, push the sealing plate 413 to continue moving and stretch the sealing spring 412, so that the sealing grooves 410 are closely attached to each other to seal the bottom end of the collection box 401, thereby isolating the samples in different collection boxes 401 and preventing the samples from being mixed. Moreover, the samples stored in the collection box 401 are all soils sampled at corresponding depths. After all the collection boxes 401 are filled, maintain the pressure on the rotating plate 8 and pull out the barrel body 1 from the ground, and the sampling cylinder 12 can be pulled out of the ground together through the threaded connection between the threaded clamp 21 and the sampling cylinder 12;

[0036] Release the rotating plate 8, and the rotating plate 8 can drive the plug plate 10 to reset through the sliding rod 11 under the action of the support spring 7, so as to press the air in the air chamber 9 back into the restriction chamber 16, and at the same time, pump the air in the connection chamber 19 back into the air chamber 9, so that the restriction plate 18 and the threaded clamp 21 are reset under the action of the restriction spring 17 and the connection spring 20 respectively. At this time, the sampling cylinder 12 can automatically fall out of the through slot 2 under the action of gravity. Inverting the sampling cylinder 12 can pour out the remaining soil in it. At this time, the corresponding collection box 401 can be taken out of the placement groove 3 according to the sampling depth for detection. After the detection is completed, pour out the soil sample in the collection box 401, and the sealing plate 413 can rebound into the sealing groove 410 under the action of the sealing spring 412, and squeeze the air in the sealing groove 410 into the power chamber 402, so that the air pushes the air plate 408 to reset, and drives the partition 404 to reset through the toothed rod 407, the gear set 406 and the rack 405, which is convenient for the next use.
