In this solution, a handle is provided on the wall of the pushing screw 12, and the pushing handle drives the pushing screw 12 to rotate, so that the pushing screw 12 pushes the sampling tube 20 into the soil to achieve sampling. The support rod 11 forms an L-shaped rod body structure, and a conical limiting protrusion is provided at the bottom of the support rod 11. Sampling is achieved by stepping on the support rod 11 and rotating the handle by hand.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a collecting structure for sampling is provided at the end of the pushing screw 12, and the collecting structure includes a sampling barrel 20, a discharge window 21 and a baffle 22. The sampling barrel 20 is fixedly connected to the pushing screw 12, and a discharge window 21 for taking out samples is provided on the wall of the sampling barrel 20. The baffle 22 is located inside the baffle 22, and the baffle 22 is detachably connected to the sampling barrel 20. The sampling barrel 20 forms a cylindrical structure, and the discharge window 21 is provided on the circumferential surface of the sampling barrel 20. The height of the discharge window 21 is less than the height of the sampling barrel 20. The discharge window 21 passes through the wall of the sampling barrel 20 and is connected to the chamber of the sampling barrel 20. The discharge window 21 forms an arc groove, and the baffle 22 forms an arc plate adapted to the discharge window 21. The baffle 22 and the sampling barrel 20 are To form a complete cylinder, the circumferential length of the baffle 22 should be greater than half of the circumferential length of the sampling tube 20, so as to ensure that the discharge window 21 will not interfere with the discharge of the sample. By setting a detachable baffle 22, when the baffle 22 and the sampling tube 20 are installed, the baffle 22 will block the discharge window 21, and the baffle 22 and the sampling tube 20 together form a cylinder for sampling. The soil screwed into the cavity of the sampling tube 20 is the sample. When the sampling tube 20 is screwed out of the soil, the sample is located in the cavity of the sampling tube 20. The baffle 22 and the sampling tube 20 can be removed, and the discharge window 21 is in an open state, so that it is easy to take out the sample and keep the integrity of the sample as much as possible. It has the characteristics of easy sample removal and easy practical operation.

[0025] like Figure 4 and Figure 5As shown, the collecting structure also includes a limiting nut 23, a stop groove 24 and a positioning block 25. The positioning block 25 is elastically connected to the baffle 22. The wall surface of the sampling tube 20 is provided with a stop groove 24. The positioning block 25 can be inserted into the stop groove 24 to lock the lower end of the baffle 22. The limiting nut 23 is threadedly connected to the sampling tube 20 and locks the upper end of the baffle 22. The outer wall of the sampling tube 20 is provided with a thread. The limiting nut 23 is adapted to the sampling tube 20 and is threadedly connected to the outer wall of the sampling tube 20. The stop groove 24 is provided on the inner bottom surface of the sampling tube 20 at the discharge window 21. The stop groove 24 forms a notch adapted to the positioning block 25. The end surface of the baffle 22 is provided with a sliding channel adapted to the positioning block 25. An elastic member is provided in the sliding channel. The positioning block 25 slides in the sliding channel and is connected to the elastic member. The elastic member includes a spring but is not limited to a spring. As a supplement to the above scheme It is clear that the cross-sectional area of ​​the anti-slip groove 24 should be slightly larger than the cross-sectional area of ​​the positioning block 25, so that the positioning block 25 can be inserted into the anti-slip groove 24 at an angle. By setting the positioning block 25, the elastic member takes a spring as an example. When the baffle 22 is installed, the positioning block 25 is squeezed into the sliding channel, and the spring is in a compressed state, pushing the baffle 22 into the discharge window 21. When the positioning block 25 is facing the anti-slip groove 24, the spring pushes the positioning block 25 into the anti-slip groove 24, and then the lower end of the baffle 22 is limited.

During the rotating sampling process of the sampling tube 20, the baffle 22 will not fall off. It has the characteristic of easy disassembly and assembly of the baffle 22, and at the same time can ensure the smoothness and integrity of the inner and outer walls of the sampling tube 20, which is conducive to the sampling tube 20 being screwed into the soil.

[0026] The working principle of the utility model is as follows: the support rod 11 forms an L-shaped rod structure, and a conical limiting protrusion is provided at the bottom of the support rod 11. Sampling is achieved by stepping on the support rod 11 and rotating the handle by hand. When the baffle 22 is installed, the positioning block 25 is squeezed into the sliding channel, and the spring is in a compressed state, pushing the baffle 22 into the discharge window 21. When the positioning block 25 is facing the anti-slip groove 24, the spring pushes the positioning block 25 into the anti-slip groove 24, and then the lower end of the baffle 22 is limited, and the rotation limit The limiting nut 23 is gradually rotated to wrap the baffle 22. At this time, the baffle 22 is limited in the discharge window 21. The baffle 22 and the sampling barrel 20 together form a cylinder for sampling. The soil screwed into the cavity of the sampling barrel 20 is the sample. When the sampling barrel 20 is screwed out of the soil, the sample is located in the cavity of the sampling barrel 20. The baffle 22 and the sampling barrel 20 can be removed, and the discharge window 21 is in an open state, which makes it easy to take out the sample and ensures the integrity of the sample as much as possible.
