[0016] 1. The present invention can drill soil samples from underground and temporarily store them in a sampling tube during sampling.

The present invention can adjust the device according to the sampling situation, so as to smoothly complete the sampling and sample storage, and avoid the mixing of sample forces during sampling. In the sampling process, the sampling tube can be kept stable to prevent the sampling tube from being disengaged or deflected. Through the synergistic effect of the air cavity, the limiting plate and the threaded clamp, the fixed state of the sampling tube can be dynamically adjusted during the sampling process. When the sampling tube penetrates deep into the soil, the change in air pressure drives the limiting plate to disengage from the card slot, allowing the sampling tube to move downward; at the same time, the threaded clamp engages with the sampling tube thread through elastic pressure to prevent the sampling tube from being deflected or disengaged, ensuring the verticality and stability of the drilling process and reducing the need for manual intervention.

[0018] 3. The present invention uses an integrated mechanical transmission and air pressure control system, so users can complete the collection and isolation of soil at different depths through simple rotation and pressing operations, reducing the steps of frequent container replacement or manual stratification in the traditional sampling process, significantly improving the sampling efficiency and reducing the complexity of operation.

[0024] In some specific embodiments, the above-mentioned breaking plate 5 and drilling plate 13 are both spiral-shaped.

[0025] When in use, the device is adjusted according to the sampling situation, so as to smoothly complete the sampling and storage of samples, and avoid the mixing of samples during sampling. In the sampling process, the sampling tube 12 can be kept stable to prevent the sampling tube 12 from being disengaged or deflected. Through the synergistic effect of the air cavity 9, the limiting plate 18 and the threaded clamp 21, the fixed state of the sampling tube 12 can be dynamically adjusted during the sampling process. When the sampling tube 12 penetrates into the soil, the air pressure change drives the limiting plate 18 to disengage from the card slot 14, allowing the sampling tube 12 to move downward; at the same time, the threaded clamp 21 is engaged with the thread of the sampling tube 12 through elastic pressure to prevent the sampling tube 12 from being deflected or disengaged, ensuring the verticality and stability of the drilling process, and reducing the need for manual intervention. When in use, through the integrated mechanical transmission and air pressure control system, the user only needs to complete the collection and isolation of soils at different depths through simple rotation and pressing operations, reducing the steps of frequently changing containers or manual stratification in the traditional sampling process, significantly improving the sampling efficiency, and reducing the complexity of operation.

[0026] When using the crop soil sample collector of the present invention, first place the collection box 401 into the placement slot 3, then insert the sampling tube 12 into the through slot 2, and then the sampling tube 12 is inserted 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, and the rack 405 drives the rack 405 to rotate through the gear set 406, so as to push the air plate 408 to slide in the power chamber 402, and the slider 409 and the slide groove 403 restrict the air plate 408 to avoid the air plate 408 08 deflects during the movement, and 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 get stuck in the card slot 14. The gears of different sizes on the gear set 406 can enlarge the travel of the rack 405 to drive the air plate 408 to move, thereby pressing 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 tube 12 is fully inserted, the device is placed on the sampling point; Then, the rotating plate 8 is rotated, and the rotating plate 8 can drive the barrel body 1 to rotate through the slide bar 11, and then drive the sampling barrel 12 to rotate synchronously through the limiting plate 18, so that the drilling plate 13 drills into the ground and sends the soil into the sampling barrel 12 for temporary storage. In the process of the barrel body 1 driving the sampling barrel 12 to drill into the ground, the barrel body 1 can drill into the ground together through the soil-breaking plate 5 until the predetermined sampling depth is reached. At this time, the rotating plate 8 is pressed downward on the barrel body 1, and the plug plate 10 is driven to descend in the air cavity 9 through the slide bar 11. The slide groove 403 can limit the slide bar 11, thereby ensuring that the plug plate 10 will not deflect during the movement; The air in the air cavity 9 is pressed into the connecting cavity 19, and the air in the limiting cavity 16 is sucked into the air cavity 9, so that the air pressure in the connecting cavity 19 and the limiting cavity 16 changes, thereby driving the limiting plate 18 and the threaded clamp 21 to move in the limiting cavity 16 respectively, and the limiting plate 18 is pulled out from the card slot 14 and compresses the limiting spring 17, while the threaded clamp 21 is pressed on the sampling tube 12 and stretches the connecting spring 20. At this time, the rotating plate 8 is rotated again to rotate the barrel 1, and the sampling tube 12 is continuously pushed downward through the threaded connection between the threaded clamp 21 and the sampling tube 12. As the sampling tube 12 moves downward in the through groove 2, the soil sample temporarily stored in the sampling tube 12 will enter the collecting box 401 from the sampling tube 12 as the subsequent soil enters. The soil sample can continue to pressurize the partition fence 404, and the partition fence 404 can prevent the soil from entering the power chamber 402. After the sampling tube 12 is released from the lower end of the collection box 401, the compressed air in the power chamber 402 can be rapidly squeezed into the sealing groove 410, pushing the sealing plate 413 to continue to move and stretch the closing spring 412, so that the sealing grooves 410 fit tightly together, and the bottom end of the collection box 401 is sealed, so that the samples in different collection boxes 401 are isolated to avoid mixing between samples, and the samples stored in the collection box 401 are all soil sampled at the corresponding depth. After all the collection boxes 401 are filled, the pressure on the rotating plate 8 is maintained and the cylinder body 1 is pulled out from the ground, and the sampling tube 12 can be pulled out of the ground together through the threaded connection of the threaded clamp 21 and the sampling tube 12; When the rotating plate 8 is released, the rotating plate 8 can, under the action of the supporting spring 7, drive the plug plate 10 to reset through the sliding rod 11, thereby pressing the air in the air cavity 9 back to the limiting cavity 16, and at the same time, draw the air in the connecting cavity 19 back into the air cavity 9, so that the limiting plate 18 and the threaded clamp 21 are reset under the action of the limiting spring 17 and the connecting spring 20 respectively. At this time, the sampling tube 12 can automatically escape from the through groove 2 under the action of gravity, and the residual soil in the sampling tube 12 can be poured out by turning it upside down. At this time, the corresponding collecting box 401 can be taken out from the placing groove 3 according to the sampling depth for detection. After the detection is completed, the soil sample in the collecting box 401 is poured out, and the sealing plate 413 can rebound into the sealing groove 410 under the action of the closing spring 412, and squeeze the air in the sealing groove 410 into the power cavity 402, so that the air pushes the air plate 408 to reset, and drives the partition 404 to reset through the gear rod 407, the gear set 406 and the rack 405, so as to facilitate the next use.
