[0016] Beneficial effects of the present invention:
[0017] (1) In the present invention, the collection component of the device is provided with a barrel body, an auger drill bit and a collection tube. When the device collects frozen soil microorganisms, it is necessary to first use the auger drill bit to break the frozen soil layer. The frozen soil layer drilled by the auger drill bit is sent to the barrel body through the collection tube to prevent the frozen soil layer from falling directly to the ground. In this way, on the one hand, the frozen soil layer is prevented from falling directly to the ground, which is convenient for the subsequent landfill of the excavated frozen soil layer, reduces the damage to the original ecological environment of the frozen soil, and helps to maintain the stability and biodiversity of the frozen soil layer. On the other hand, the frozen soil layer is prevented from falling into the excavation sampling pit, thereby effectively avoiding the frozen soil layer soil from being collected together with the microbial samples, thereby reducing the contamination of the microorganisms by the frozen soil layer.
[0018] (2) In the present invention, the carrier plate of the adjustment component of the device is provided with a first support leg and a first adjustment leg cooperating with the first support leg. The arrangement of the first support leg and the first adjustment leg, on the one hand, enables the carrier plate to use the first support leg and the first adjustment leg to be stationed on the frozen soil during the collection operation, and cooperate with the stationing of the second support leg and the second adjustment leg of the support component, so that the device can be stationed on the frozen soil more stably, reduce vibration and displacement during the collection process, ensure the accuracy of the collection point, and improve the representativeness of the collected microbial samples. On the other hand, when the device uses the first support leg and the first adjustment leg support rod, the second support leg cooperating with the second support leg can be stationed on the frozen soil. The adjusting legs are retracted, and at the same time, the supporting assembly can be driven to move in the opposite direction through the first cross bar and the second cross bar. After the supporting assembly is moved, the second supporting legs and the second adjusting legs can be used for support again, and the adjusting assembly can be driven to move through the first cross bar and the second cross bar. By alternately moving the positions of the supporting assembly and the adjusting assembly, the device can achieve a self-propelled function, reducing the need for manual handling, thereby reducing the labor intensity of operators carrying the equipment on frozen soil, allowing the equipment to be quickly moved from one collection point to another, increasing the flexibility of collection, and at the same time, expanding the operating range of the equipment, allowing the equipment to collect in a larger area.
[0019] (3) In the present invention, a collection scraper is arranged on the cylinder. After the auger drill breaks the frozen soil, the cylinder enters the excavated pit. Driven by the fifth motor, the cylinder rotates, and the collection scraper is unfolded under the drive of the rotating cylinder. The collection scraper scrapes the inner wall of the pit, scrapes the sample in the pit and drops it into the collection dish, thereby completing the collection and storage of the frozen soil microbial sample. Through this collection method, on the one hand, the cylinder follows the auger drill into the bottom of the frozen soil, and there is no need to take out the auger drill, and the microbial sample can be directly collected, thereby realizing continuous operation, reducing equipment adjustment and preparation time, and improving collection efficiency. At the same time, it avoids the secondary interference to the frozen soil layer caused by taking out the auger drill, thereby maintaining the originality and reliability of the sample. On the one hand, the collection scraper is a fish-scale-shaped device, which takes samples from the side walls of the pit excavated by the auger drill bit, avoiding the problem of uneven sampling. After the collection is completed, the cylinder is rotated in the opposite direction, and the collection scraper can be retracted under the drive of the cylinder. When the collection cylinder is taken out, the collection scraper will not scrape the soil of the permafrost layer into the collection dish, reducing cross-contamination between samples and improving the purity of the samples. The scraped samples fall directly into the collection dish, simplifying the sample collection process and reducing sample transfer and loss. On the other hand, multiple layers of collection scrapers and multiple collection dishes are arranged on the cylinder, which can simultaneously collect multiple layers of microbial samples under the permafrost, which is helpful to study the distribution and characteristics of microorganisms at different depths. The collected samples are stored in layers, which is convenient for subsequent classification, labeling and laboratory analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In an optional implementation of this embodiment, the auger drill bit 8 is rotatably fitted in the barrel 701, and the diameter of the auger drill bit 8 is adapted to the inner diameter of the barrel 701, and a sixth motor 801 is vertically installed on the top of the connecting plate 601 to drive the auger drill bit 8 to rotate.
[0043] When in use, first, the support assembly 1 is used to adjust the device to a position suitable for collection, and the second adjustment leg 402 is adjusted to keep the device balanced and at a suitable height. The first cross bar 504 and the second cross bar 508 are driven to move the position of the adjustment assembly 2 so that the collection assembly 3 is aligned with the collection point. The first adjustment leg 204 is adjusted to further support the device. Then, the first adjustment leg 204 and the second adjustment leg 402 are synchronously adjusted to move the device downward, so that the collection assembly 3 moves downward. When the auger drill bit 8 in the collection assembly 3 touches the frozen ground, the sixth motor 801 is turned on to rotate the auger drill bit 8 to auger. The auger bit 8 rotates and moves downward to break the frozen soil layer. At the same time, the collection tube 7 follows and enters the pit excavated by the auger bit 8. Finally, after the collection scraper 705 on the collection tube 7 reaches the collection depth, the fifth motor 704 drives the cylinder body 701 to rotate, and the collection scraper 705 is unfolded. The collection scraper 705 rotates with the cylinder body 701 to scrape the sample in the pit into the collection dish 706, completing the collection and storage of the microbial sample. After the collection dish 706 completes the collection of the sample, the cylinder body 701 is rotated in the opposite direction, the collection scraper 705 is gathered and folded again, and the collection tube 7 is lifted up out of the pit, and then the pit is filled with the soil drilled out by the auger bit 8.
