[0050] Working principle: Push the cart 100 to the area where soil needs to be taken, start the cylinder 510 to drive the cylinder 520 to descend, and the cylinder 520 drives the soil cone 530 to descend and insert into the soil to ensure the stability of the entire device when taking soil, start the lifting motor 210, the lifting motor 210 drives the screw rod 220 to rotate, the screw rod 220 drives the lifting plate 240 to descend under the action of the thread, and the lifting plate 240 drives the fixed plate 250 to descend, and at the same time start the soil drilling motor 310, the soil drilling motor 310 drives the connecting shaft 320 to rotate, the connecting shaft 320 drives the connecting pipe 330 to rotate, the connecting pipe 330 drives the sampling tube 340 to rotate, the fixed plate 250 descends and drives the soil drilling mechanism 300 to descend, so that the soil is separated and enters the sampling tube 340, and the inner wall of the sampling tube 340 is coated with oil lubricant to facilitate the removal of soil samples. When the sampling tube 340 takes soil, the soil pushes the push plate 440 to rise, and the push plate 440 drives the telescopic rod 42 0 retracts and compresses the first spring 430. At this time, the lock head 451 is in the square hole 441 and compresses the second spring 455. When the push plate 440 rises and drives the lock head 451 to reach the locking hole 352, the second spring 455 rebounds and drives the lock head 451 to extend into the locking hole 352 and lock the push plate 440. At this time, the sampling is completed. The reverse lifting motor 210 makes the drilling mechanism 300 rise, the nut 720 is loosened and the screw rod 710 is removed to separate the connecting pipe 330 from the connecting shaft 320, so as to remove the sampling tube 340, and then the lock head 451 is pressed to make the lock head 451 descend. The lock head 451 drives the guide rod 452 to descend and extend into the round hole 454, so that the push plate 440 is released. At this time, the first spring 430 rebounds and drives the push plate 440 to descend and extend the telescopic rod 420. The push plate 440 pushes the soil sample out of the sampling tube 340 to avoid damage to the sampling tube and breakage of the soil sample due to manual knocking;

[0051] In this step, when the sampling tube 340 rotates to take soil, the push plate 440 is pushed upward so that the lock head 451 falls into the locking hole 352. After the sampling tube 340 is removed, the push plate 440 is unlocked by pressing the lock head 352, so that the first spring 430 rebounds and drives the push plate 440 to push the soil sample, so that the soil sample is pushed out of the sampling tube 340, thereby avoiding damage to the sampling tube 340 and breakage of the soil sample due to manual knocking.

[0052] See also Figure 1-4As shown, in this embodiment, on the basis of the above structure, a first locking groove 341 is provided on the side wall of the sampling barrel 340, a second locking groove 351 is provided on the side wall of the inspection door 350, and the circular plate 410 is symmetrically fixedly connected with the locking posts 411, and the locking posts 411 are placed in the first locking groove 341 and the second locking groove 351, a second threaded hole 353 is provided on the side wall of the inspection door 350, and there are multiple second threaded holes 353, a first threaded hole 342 is provided on the side wall of the sampling barrel 340, and there are multiple first threaded holes 342, and the first threaded hole 342 and the second threaded hole 353 are threadedly connected with a screw 600, and the inspection door 350 and the sampling barrel 340 are fixed after the screw 600 is threadedly connected with the first threaded hole 342 and the second threaded hole 353;

[0053] Working principle: When the core push assembly 400 needs to be replaced, use a tool to unscrew the screw 600, open the inspection door 350, take out the locking column 411 on the circular plate 410 from the first locking groove 341, and then directly pull out the entire core push assembly 400, then insert the push plate 440 in the new core push assembly 400 into the sampling tube 340, and then lock the locking columns 411 on both sides of the circular plate 410 into the first locking groove 341, close the inspection door 350, and the upper half of the locking column 411 on the inspection door 350 can be locked, and then align the screw 600 with the second threaded hole 353 and the first threaded hole 342 and tighten it with a tool, so as to maintain the effect of automatically pushing the soil sample;

[0054] In this step, after long-term use, the pushing force of the core pusher assembly 400 in the sampling tube 340 will decrease due to the decrease in the elastic force of the first spring 430. The core pusher assembly 400 can be replaced by opening the inspection door 350, thereby maintaining the effect of automatically pushing the soil sample.
