The adjustment and protection module 5 can compact and fit the soil on the inner wall of the sampling hole to prevent the collapse of the soil inner wall during the sampling process, which may cause the sampling work to be unable to be completed. The sampling module 10 can sample the soil at a specified position and can automatically replace the sampling cylinder 1010 inside the sampling hole.

[0019] Referring to Figures 1 - 6 , in a preferred embodiment, the adjustment and protection module 5 further includes a rubber airbag 507, a guiding outer frame 505, and a plurality of arc-shaped seats 513. The rubber airbag 507 is arranged on the outer wall of the connecting rod member 13. The top of the fixed bracket 501 is fixedly connected with a negative pressure pump 502. The output end of the negative pressure pump 502 is provided with a conveying pipeline 503. The output end of the conveying pipeline 503 is provided with a communication bin 504.

In a specific application scenario, the adjustment and protection module 5 is applicable to the process of compacting and stabilizing the soil on the inner wall of the sampling hole. That is, when the adjustment and protection module 5 is in use, the elastic mounting member 511 and the cylindrical pressure rod 510 can be supported by the rubber airbag 507 provided, so as to initially compact and stabilize the soil inside the sampling hole. By rotating the adjustment and protection module 5 through the gripping member 4, the soil inside the sampling hole can be compacted and stabilized for the second time, enhancing the stability and strength of the soil, avoiding the collapse of the soil inside the sampling hole, and facilitating the smooth progress of subsequent sampling work. At the same time, the adjustment and protection module 5 can be retracted inside the protection sleeve 8, preventing the equipment from being damaged when not in use and extending the service life of the equipment.

After compaction, while turning off the negative pressure pump 502, pull out the insertion rod 6. The staff turns the mounting disc 2 through the gripping member 4 to adjust the angle of the mounting disc 2. After the adjustment is completed, insert the insertion rod 6 into the inside of another locking hole 7. After locking, start the negative pressure pump 502 again to make the rubber airbag 507 bulge, and prop up the elastic mounting member 511 and the columnar pressure rod 510 again to perform secondary compaction and fitting on the inner wall of the hole; Step 3: Start the drive motor 1004. The drive motor 1004 drives the sampling cylinder 1010 to rotate. After rotating to the position of the feed slot, turn off the drive motor 1004. At the same time, turn on the power motor 1005. The power motor 1005 drives the shaft rod 1008 to rotate. Under the action of the shaft rod 1008, the sampling scraper 1006 starts to sample the soil on the inner wall of the hole. The sampled soil enters the inside of the sampling cylinder 1010 through the guiding frame 1009. After sampling is completed, turn off the power motor 1005; Step 4: After sampling is completed, turn off the negative pressure pump 502. At the same time, turn on the electric push rod 3. Under the action of the limiting spring 512 and the guide wheel 515, the elastic mounting member 511 and the cylindrical pressure rod 510 contract and enter the inside of the protective sleeve 8 at the same time. When the top of the connecting member 9 contacts the bottom of the protective sleeve 8, turn off the electric push rod 3, and at the same time take out the device from the sampling hole to obtain the sampled soil inside the sampling bin 1002.

A forestry soil detection and sampling method, using the forestry soil detection and sampling device according to claim 9, characterized in that, The steps include: Step 1: Place the installation platform (1) on the ground above the sampling hole, open the electric push rod (3), transport the sampling module (10) and the adjustment and protection module (5) into the hole, and then close the electric push rod (3); Step 2: Inflate the rubber airbag (507) through the negative pressure pump (502), so that the elastic mounting part (511) is propped up, and then the columnar pressure rod (510) is made to fit with the inner wall of the hole and compact the inner wall of the hole. After the initial compaction is completed, pull out the insertion rod (6), adjust the angle of the mounting plate (2), and after the adjustment is completed, insert the insertion rod (6) into another locking hole (7). After locking, start the negative pressure pump (502) again, so that the rubber airbag (507) is inflated, and the elastic mounting part (511) and the columnar pressure rod (510) are propped up again, and the inner wall of the hole is compacted and fitted for a second time; Step 3: Open the sampling module (10) to sample the soil at a specified depth; Step 4: After sampling is completed, the electric push rod (3) is opened, and the elastic mounting member (511) and the cylindrical pressure rod (510) are retracted under the action of the limit spring (512) and the guide wheel (515), and enter the interior of the protective tube sleeve (8). When the top of the connecting member (9) contacts the bottom of the protective tube sleeve (8), the electric push rod (3) is closed, and the device is taken out of the sampling hole.
