[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless substances. If you want to test the remediated soil, you inevitably need to collect soil samples.

[0003] In the prior art, soil samples are mostly collected through a collection device. The collection device can be used to collect soil samples of different depths by adjusting the descending height. Although the collection device is convenient for extracting samples of different depths, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks an automatic non-destructive feeding mechanism, which leads to the traditional sampling of the sample itself being pushed out by hard force, resulting in serious deformation of the sample column and separation and disassembly of the spliced ​​sample tube for sampling.

[0046] The present invention also discloses a method for using the adjustable soil remediation sample collection device, which specifically comprises the following steps:

[0047] S1. Preparing for sampling

[0048] Step 1: Assembling the semi-arc inner cylinder 710: First, move the device to the sampling location, and then sequentially assemble the two semi-arc inner cylinders 710 into the interior of the outer cylinder 10. During assembly, the semi-arc inner cylinder 710 is firmly assembled into the interior of the outer cylinder 10 through the sliding fit between the fitting plate 725 and the fitting groove 724, and the locking of the grooved clamping seat 711 and the inclined block 709;

[0049] The specific assembly steps are as follows: Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the semi-arc inner cylinder 710 is sent from bottom to top into the outer cylinder 10 according to the sliding track of the fitting plate 725 and the fitting groove 724. When the outer cylinder 10 moves from bottom to top, it carries the grooved clamping seat 711 to press the inclined block 709, causing the inclined block 709 to retract and then elastically return to the inside of the grooved clamping seat 711, and the assembly is completely locked;

[0050] Step 2: sampling, driving the second servo motor 601 in the lifting control mechanism 6, causing the threaded sleeve 603 in the lifting control mechanism 6 to descend through the mounting plate 3 carrying the first servo motor 4, the outer cylinder 10 and the semi-arc inner cylinder 710, and synchronously driving the outer cylinder 10 to rotate through the first servo motor 4, so as to cause the outer cylinder 10 and the semi-arc inner cylinder 710 to sample together;

[0051] The specific steps are: according to Figure 1 and Figure 2 As shown, the second servo motor 601 is started, and the second servo motor 601 drives the threaded rod 602 to rotate. The threaded rod 602 rotates the threaded sleeve 603 on its surface to carry the mounting plate 3, the first servo motor 4, the rotating shaft 5, the outer cylinder 10 and the assembled semi-arc inner cylinder 710 to descend. When the outer cylinder 10 and the semi-arc inner cylinder 710 are about to pass through the opening 801 and contact the ground, the first servo motor 4 is started, and the first servo motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the outer cylinder 10 and the semi-arc inner cylinder 710 to rotate, thereby descending and rotating to take samples.

[0052] S2, automatic sample stripping: After the outer cylinder 10 and the semi-arc inner cylinder 710 have obtained the sample together, the outer cylinder 10 is reset to its limit height, so that the semi-arc inner cylinder 710 can be automatically separated from the inner part of the outer cylinder 10 through the cooperation of the sample self-separation mechanism 7 as a whole, thereby completing the sample stripping;

[0053] The specific steps are: according to Figure 3 , Figure 6 , Figure 7 , Figure 8As shown, after the outer cylinder 10 and the semi-arc inner cylinder 710 obtain the sample together, the second servo motor 601 is then used to reversely drive the threaded rod 602, so that the threaded sleeve 603 carries the mounting plate 3, the first servo motor 4, the rotating shaft 5, the outer cylinder 10 and the assembled semi-arc inner cylinder 710 to rise and reset. The rotating shaft 5 rises and synchronously carries the first sleeve 701, the telescopic plate 702, the second sleeve 704, and the ring plate 712 to rise. As the ring plate 712 rises, the ring plate 712 gradually contacts the bottom of the L-shaped blocking rod 713 and is blocked by the L-shaped blocking rod 713. As the rotating shaft 5 continues to rise, the blocked ring plate 712 is relatively in a downward position. The downward movement of the ring plate 712 will drive the L-shaped pressure rod 705 through the second sleeve 704 as a medium. The L-shaped pressure rod 705 descends, driving the circular plate 707 and the semi-arc inner cylinder 710 to descend. The semi-arc inner cylinder 710 descends and gradually extends outward from the outer cylinder 10. The L-shaped pressure rod 705 descends and drives the inclined plate 715 to descend at the same time. The inclined plate 715 descends and is squeezed and contacted with the rising rotating rod 718 in the outer cylinder 10. After being squeezed by the rotating rod 718, the inclined plate 715 drives the L-shaped pressure rod 705 to move, prompting the L-shaped pressure rod 705 to drive the inclined block 709 to disengage the locking cooperation with the grooved card seat 711. At this time, the locking cooperation is lost and the semi-arc inner cylinder 710 will pass through the thrust of the circular plate 707, and then carry the sample to slide downward out of the outer cylinder 10, completing the sample stripping, and finally manually stripping the semi-arc inner cylinder 710 from the sample column after being taken out.

[0054] S3, automatic anti-falling: when the outer cylinder 10 carrying the semi-arc inner cylinder 710 is reset and the semi-arc inner cylinder 710 is automatically separated, the sample self-detaching mechanism 7 can also cooperate with the automatic receiving mechanism 9 to cause the receiving frame 904 in the automatic receiving mechanism 9 to automatically extend to the bottom of the outer cylinder 10 and receive the semi-arc inner cylinder 710 accordingly;

[0055] The specific steps are: according to Figure 1 , Figure 6 and Fig.12 As shown, when the above-mentioned rotating shaft 5 carries the ring plate 712 and contacts the L-shaped baffle rod 713, the ring plate 712 will simultaneously press the control button 905 set at the bottom of the left L-shaped baffle rod 713. After the control button 905 retracts under force, the first telescopic rod 901 is automatically started, and the first telescopic rod 901 drives its extended end to extend backward, and simultaneously drives the bracket 902 and the receiving frame 904 to move backward until the backward position of the receiving frame 904 is centered with the bottom discharge port of the outer cylinder 10.

[0056] S4, cleaning the outer wall of the outer cylinder 10: When the lifting control mechanism 6 drives the outer cylinder 10 to reset, and the outer cylinder 10 passes through the sample self-detaching mechanism 7 to automatically peel off the semi-arc inner cylinder 710, the lifting control mechanism 6 synchronously drives the scraper blade 803 and the brush layer 809 in the soil cleaning mechanism 8 to scrape and clean the soil on the outer wall of the outer cylinder 10 that rises and resets in turn;

[0057] The specific steps are: according to Fig. 9 , Fig.10 and Fig.11 As shown, the second servo motor 601 drives the threaded rod 602 by reverse rotation, prompting the mounting plate 3, the first servo motor 4, and the rotating shaft 5 to carry the outer cylinder 10 to reset and rise to withdraw the material, and the threaded rod 602 synchronously drives the second pulley 805 to rotate, and the second pulley 805 synchronously cooperates with the belt 806 and the first pulley 804 to drive the first pulley 804 to rotate, and the rotating ring 802 synchronously drives the scraper blade 803 to rotate. The rotation of the scraper blade 803 will synchronously clean the soil on the outer wall of the outer cylinder 10 drawn out of the pit;

[0058] When the rotating ring 802 drives the scraper blade 803 to rotate, the rotating ring 802 synchronously drives the first gear 807 to rotate. The first gear 807 rotates and meshes with the second gear 810, prompting the second gear 810 to drive the cleaning drive rod 808 and the brush layer 809 to rotate.
