[0039] During operation, the staff pulls or pushes the entire frozen soil microorganism stratified sampling device to a designated position through the handle 3, so that the through slot on the first mounting plate 2 is located above the sampling area, and then controls and starts the first electric slide rail 208 to drive the first electric slider 209 to move downward, and the first electric slider 209 drives the second mounting plate 2010 to drive the rotating drum 2011 to move downward, and the rotating drum 2011 moves downward and is inserted into the frozen soil. In order to allow the rotating drum 2011 to be smoothly inserted into the hard frozen soil, during the downward movement of the rotating drum 2011, the control motor 204 is started to drive the first transmission shaft 205 to drive the column gear 206 to rotate, the column gear 206 drives the spur gear 2012 to rotate, and the spur gear 2012 drives the rotating drum 2011 to rotate, so that the rotating drum 2 011 also rotates during the downward movement, so that it can be smoothly inserted into the hard frozen soil. After inserting to a predetermined depth, the motor 204 is controlled to start and stop, so that the rotating drum 2011 stops rotating. Then the first electric slide rail 208 is controlled to drive the first electric slider 209 to move upward, so that the rotating drum 2011 moves upward until the rotating drum 2011 is located above the straight push rod 305. In this way, the frozen soil sample in the rotating drum 2011 is taken out, and the sampling of the frozen soil is completed; then, based on looking from top to bottom, the electric rotating shaft 202 is controlled to start and drive the second transmission shaft 207 and its associated parts to rotate ninety degrees clockwise, and the second transmission shaft 207 drives the first electric slide rail 208 and its associated parts to rotate ninety degrees, so that the rotating drum 2011 is located directly above the straight push rod 305.

[0040] Then, the second electric slide rail 302 is controlled to start to drive the second electric slider 303 to move upward, and the second electric slider 303 drives the third mounting plate 304 to drive the straight push rod 305 to move upward, and the straight push rod 305 moves upward and is inserted into the rotating drum 2011, pushing the frozen soil column in the rotating drum 2011 to move upward, and moves to the top of the frozen soil column and is inserted into the fastening ring 3014, and the frozen soil column squeezes the elastic part on the inner wall of the fastening ring 3014, and the elastic part rebounds and squeezes the frozen soil column, so that the frozen soil column is stuck and fixed, and then the second electric slide rail 302 is controlled to drive the second electric slider 303 to move downward and reset, and then the electric rotating shaft 202 is controlled to start to drive the second transmission shaft 207 and its associated parts to rotate counterclockwise by ninety degrees to reset; then the fourth electric slide rail 401 is controlled to start to drive the fourth electric slider 403 and its associated parts to move upward intermittently, and whenever it stops, the second electric push rod 404 is controlled to start to drive the hardness tester 405 to start, so that the hardness tester The probe of the instrument 405 extends to the outer wall of the frozen soil column to detect the hardness of the frozen soil layer. When the hardness reaches a specific value, that is, the frozen soil needs to be layered, the fourth electric slide rail 401 is controlled to stop driving the fourth electric slider 403 to move upward, and then the two third electric push rods 407 are controlled to start at the same time to drive the two layering cylinders 408 to move toward each other. In the process of moving toward each other until they contact each other, the frozen soil column is cut into two parts, the upper part is harder and the lower part is softer. After cutting, the lower frozen soil column falls into the second collecting barrel 4011 below, and the upper frozen soil column is received by the two layering cylinders 408 after closing. At the same time, the two elastic cylinders 409 in the two layering cylinders 408 move toward each other and contact the frozen soil column to clamp the lower part of the frozen soil column; when the fourth electric slider 403 and its associated parts move upward, the two baffles 4010 move upward and contact the telescopic end of the shrinking sleeve 3011. After contact, the shrinking sleeve 3011 is driven to shrink, so that the upper part of the frozen soil column is always surrounded by the shrinking sleeve 3011;Then the vegetation on the upper surface of the frozen soil column is pulled out. However, since the frozen soil freezes the roots of the vegetation, the stems of the vegetation are usually disconnected from the root ends when they are pulled out, that is, the roots of the vegetation still remain in the frozen soil, which will affect the subsequent sampling and research of microorganisms. Therefore, at this time, the external air pump is controlled to start to pass hot air with a temperature suitable for the survival of microorganisms into the shrink sleeve 3011 to accelerate the softening of the frozen soil layer. After the frozen soil column softens, the two third electric slide rails 3012 in the left and right directions are controlled to drive the two third electric sliders 3013 to move downward, and the two third electric sliders 30 13 drives the two annular pressure plates 3016 to move downward, and the two annular pressure plates 3016 move downward to contact the plurality of push pins 3015, forcing the plurality of push pins 3015 to slide toward the center point of the fastening ring 3014 at the same time. When the push pins 3015 slide, the spring 3010 is compressed, and the plurality of push pins 3015 slide toward the center point of the fastening ring 3014 and penetrate into the frozen soil layer. Then, the four third electric slide rails 3012 are controlled to start and drive the associated parts of the four third electric slide blocks 3013 to move upward, and the fastening ring 3014 and the plurality of push pins 3015 penetrate into the frozen soil are moved upward. 5 moves upward, the fastening ring 3014 moves upward and separates from the frozen soil column, and the plurality of push pins 3015 slide upward to separate the roots of the vegetation from the frozen soil column, and then the first electric push rod 308 is controlled to start and drive the first collecting bucket 309 to move to the bottom of the fastening ring 3014, and then the two third electric slide rails 3012 in the left and right directions are controlled to drive the two third electric slide blocks 3013 to move upward, so that the two annular pressure plates 3016 move upward and separate from the plurality of push pins 3015, and due to the action of the spring 3010, the push pins 3015 move away from the center of the fastening ring 3014 The push pin 3015 slides in the direction of the point to reset, so that the plant roots on the push pin 3015 lose support and fall into the first collection bucket 309 for collection. Then the staff controls the second collection bucket 4011 filled with softer frozen soil columns to be removed and an empty one is placed on top. Then the two third electric push rods 407 are controlled to drive the two stratification cylinders 408 to move in opposite directions so that the upper part of the frozen soil column that is supported loses support and falls into the empty second collection bucket 4011 for collection. After the collection is completed, the four third electric slide rails 3012 are controlled to start and drive the four third electric sliders 3013 to move downward and reset. ;

[0044] When it is necessary to pull out the vegetation on the upper surface of the frozen soil column, the fourth electric push rod 502 is controlled to start driving the ninth mounting plate 503 and its associated parts to move downward until the clamping plate 509 contacts the upper surface of the frozen soil column, and then the fifth electric slide rail 505 is controlled to drive the two fifth electric sliders 5010 to slide toward each other, and the two fifth electric sliders 5010 drive the rightmost fifth electric slider 5010 and the leftmost fifth electric slider 5010 to slide toward each other on the bare rod 506, so that the scissor frame 508 shrinks to the middle, and the scissor frame 508 with The nine clamps 509 are moved to retract toward the middle, and the vegetation is clamped between two adjacent clamps 509 during the retraction process. Then the fourth electric push rod 502 is controlled to drive the ninth mounting plate 503 to move upward, so that the clamps 509 move upward to pull up the clamped plant stems. Then when the first collecting bucket 309 moves to below the fastening ring 3014, the fifth electric slide rail 505 is controlled to drive the two fifth electric sliders 5010 to slide back to back, so that the clamps 509 release the clamped vegetation, and the plant stems fall under the first collecting bucket 309 for collection.
