[0015] In order to facilitate the collection of samples, a support column located on the left side of the yield groove 11 is provided at the upper end of the bottom plate 1, and a placement box 12 with an opening facing right is provided at the upper end of the support column.

[0016] In order to facilitate the taking out of the sample, a pressure column 13 is coaxially slidably connected in the sampling tube 6, and a squeezing plate 14 is provided at the lower end of the pressure column 13.

[0017] In order to facilitate pressing the pressure column 13 , the upper end of the pressure column 13 passes through the sampling tube 6 and is provided with a pressing plate 15 .

[0018] In order to facilitate the resetting of the squeezing plate 14 , a compression spring is sleeved on the pressure column 13 and is located between the pressing plate 15 and the sampling tube 6 .

[0019] In order to facilitate the fixed limiting of the sampling tube 6, the rear end of the rotating shaft 3 passes through the support plate 2 and is coaxially slidably connected with a slide cylinder 16. The slide cylinder 16 is connected to the rotating shaft 3 via a spring. Limiting holes 17 are respectively provided on the upper side and the right side of the rear end of the support plate 2. A limiting column 18 which can be inserted into the limiting hole 17 is provided at the front end of the slide cylinder 16.

[0020] In order to facilitate the rotation of the rotating shaft 3, a handle is provided at the rear end of the slide cylinder 16.

[0021] For ease of use, the bottom end of the base plate 1 is provided with universal wheels with a rectangular distribution, and the top end of the base plate 1 is provided with a push column located on the right side of the support plate 2.

[0022] When the utility model is in use, firstly, the bottom plate 1 and the sampling tube 6 thereon are pushed to the soil area where sampling is required by the pushing column, then the first sampling point is determined, the lower end of the sampling tube 6 is aligned with the sampling point, the motor is turned on, the motor drives the driving gear 10 to rotate, the driving gear 10 drives the rotating tube 5 to rotate through the transmission gear 9, the rotating tube 5 drives the guide groove 7 thereon to rotate, the guide groove 7 drives the sampling tube 6 to move downward on the swing plate 4 through the guide column 8, after moving downward for a distance, the sampling tube 6 is inserted into the soil, the soil enters the sampling tube 6, the motor continues to rotate, after rotating a certain angle, the guide column 8 is located at the bottom of the guide groove 7, then at this time the motor drives the rotating tube 5 to rotate, starts to drive the sampling tube 6 to move upward, and after the sampling tube 6 moves upward to the initial position, the motor is turned off;

[0023] At this time, since the motor stops rotating, the sampling tube 6 will not move up and down. At this time, the sample on the first sampling point has been sampled. Then, the handle is pulled backward, and the handle drives the slide tube 16 to slide backward and stretch the tension spring backward. The slide tube 16 drives the limit column 18 to move backward, and after moving backward for a distance, it is pulled out from the limit hole 17 on the upper side. At this time, the fixed limit of the rotating shaft 3 is released, and then the handle is turned. The handle drives the swing plate 4 to swing to the left through the rotating shaft 3, and the swing plate 4 drives the sampling tube 6 thereon to swing to the left. The sampling tube 6 swings upward in the giving way slot 11. After swinging upward 90 degrees, the sampling tube 6 is located on the right side of the placement box 12. At this time, the operator releases the handle, and the slide tube 16 moves forward due to the restoring force of the spring.

[0024] After moving forward a distance, the limit column 18 is inserted into the limit hole 17 to achieve fixed limit again. Then, the pressing plate 15 is pushed to the left at this time. The pressing plate 15 drives the squeezing plate 14 to move to the left through the pressure column 13. The squeezing plate 14 squeezes the sample in the sampling tube 6 out of the sampling tube 6 to the left in the sampling tube 6. The columnar soil sample slides out of the sampling tube 6 and slides into the placement box 12 to achieve the storage of the sample. Then, the handle is pulled back again at this time to release the limit and swing it downward to make the sampling tube 6 swing downward. The sampling tube 6 swings downward at a certain angle and then returns to the initial position. At the same time, the pressing plate 15 is released after the sample is squeezed out. Due to the restoring force of the compression spring, the squeezing plate 14 is driven to slide upward to the initial position. Then, the sampling and sample storage of the first sampling point are completed at this time. Then, the bottom plate 1 is pushed again to move to the second sampling point, and the above operation is repeated.

[0025] Compared with the prior art, the utility model has the following beneficial effects: the sampling tube, rotating tube, guide groove, etc. are provided, which can realize multi-point sampling of soil during soil carbon emission monitoring. The sampling work can be automatically completed by simply turning on and off the motor. Compared with traditional manual sampling, the operation is simple and time-saving and labor-saving.
