In the process of rotating the threaded rod 5, the threaded rod 5 can be controlled to move upward or downward. The top of the threaded rod 5 is fixedly connected to the connecting rod shaft 6, and the threaded rod 5 can be driven to rotate by rotating the connecting rod shaft 6. The bottom end of the threaded rod 5 is rotatably connected to a push plate 7, and the push plate 7 can be synchronously driven to move by the upward or downward movement of the threaded rod 5. The push plate 7 is fixedly connected to a sampling tube 8 at the center position away from one side of the threaded rod 5. When the push plate 7 moves downward, the sampling tube 8 is pushed to move toward the sampling ground. Several groups of cutting blades 802 are welded to the bottom end of the sampling tube 8. The cutting blades 802 are used to cut the ground soil, so that the sampling tube 8 is inserted into the sampling soil. A collecting groove 801 is opened inside the sampling tube 8. When the sampling tube 8 is inserted into the soil to be tested, the soil is collected by the collecting groove 801.

[0031] Please refer to 1. Figure 2 and Figure 5Two sets of sliding grooves 701 are provided inside the push plate 7, and the two sets of sliding grooves 701 are symmetrically distributed on the vertical center axis of the push plate 7. The support rod 2 is used to provide support for the push plate 7.

The top size of the blocking block 10 is smaller than the bottom size. The placement groove 901 can be used to drive the blocking block 10 to move, so as to seal the bottom end of the sampling tube 8 after sampling is completed, so as to prevent the detection sample from falling off from the collecting groove 801.

[0033] Working principle: When in use, first place the sampling device base 1 on the ground, insert the pointed plug-in column 11 into the soil to improve the stability of the device when in use, then rotate the connecting rod shaft 6 clockwise to drive the threaded rod 5 to rotate, and the threaded rod 5 continuously moves downward through the thread groove 401 during the rotation process, and the threaded rod 5 drives the push plate 7 during the movement process, and the push plate 7 synchronously drives the sampling tube 8 to move downward;

[0034] Secondly, the sampling tube 8 passes through the inside of the movable groove 101 until it reaches the outside of the sampling device base 1 and contacts the soil to be tested. The sampling tube 8 continues to move until it is inserted into the inside of the soil. The collecting groove 801 collects the soil. Then, the connecting rod shaft 6 is rotated counterclockwise to drive the threaded rod 5 to move to the initial position. The threaded rod 5 also drives the sampling tube 8 back to the initial height.

[0035] Finally, move one end of the movable circular plate 9 until the blocking block 10 is completely located at the bottom end of the sampling tube 8, and temporarily seal the bottom end of the sampling tube 8 by the blocking block 10 to prevent the soil sample from slipping from the inside of the collecting tank 801, and finally complete the work.
