The telescopic end of the lifting column 2 is installed on the outer side of the support ring 3, and a conical threaded drill bit is installed at the lower end of the drill rod 12 to facilitate breaking rock and soil.

[0025] Furthermore, a threaded rod 8 is connected to the threaded hole 7, a rotating keycap 9 is installed at one end of the threaded rod 8, a clip 11 is installed at the other end of the threaded rod 8, a spring 10 is installed on the outside of the threaded rod 8, and the spring 10 is installed between the inside of the support ring 3 and the outside of the clip 11; the rotating keycap 9 is turned clockwise to push the threaded rod 8 inward, causing the clip 11 to shrink inward, thereby stabilizing the drill rod 12. Since the drill rod 12 needs to rotate, the clip 11 does not contact the drill rod 12.

[0026] Furthermore, a top sleeve 13 is installed on the outer side of the lower end of the drill rod 12, a sampling sleeve 14 is installed on the upper end of the top sleeve 13, and a tail sleeve 15 is installed on the upper end of the sampling sleeve 14; the sampling sleeve 14 is composed of two semicircular tubes, which are sleeved on the outer side of the drill rod 12. When it forms the sampling sleeve 14, its two ends are respectively sleeved and fixed by the top sleeve 13 and the tail sleeve 15.

[0027] Furthermore, a thread 16 is provided at the upper end of the inner side of the top sleeve 13, a first ring 17 is installed at the lower end of the thread 16, and a second ring 18 is installed at the lower end of the first ring 17; the inner ring of the first ring 17 is movably connected to the drill rod 12 without affecting the rotation of the drill rod 12, and the second ring 18 adopts the bearing principle, and its inner ring is fixedly connected to the drill rod 12, and the outer side of the ring is fixedly connected to the inner wall surface of the lower end of the top sleeve 13, ensuring that the rotation of the drill rod 12 is not affected while the second ring 18 plays a supporting role.

When the sampling depth is not enough, multiple drill rods 12 can be installed to increase the length for continuous sampling. The lifting column 2 belongs to the existing mature technology. Its main purpose is to make the telescopic end of the lifting column 2 rise and fall through the hydraulic principle, so as to achieve the rise and fall of the support ring 3. Since it is a well-known technology and not the focus of this design, the structure is not described in detail.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0031] Embodiment: First, place the stabilizing device consisting of the circular base 1, the lifting column 2 and the supporting circular ring 3 at the location where sampling is to be performed. Then, take out the lower end of the drill pipe 12 and pass it through the first ring 17 and the second ring 18 in the top sleeve 13. It should be noted here that there is a difference between the first ring 17 and the second ring 18. The first ring 17 stabilizes the drill pipe 12 during rotation, and the second ring 18 not only stabilizes but also supports it. Then, combine the two sampling pieces into a complete sampling sleeve 14, combine the threaded interface at its lower end with the thread 16 of the top sleeve, and then combine the tail sleeve 15 with the upper threaded interface of the sampling sleeve 14 to complete the assembly of the sampling device; then combine the connecting piece 20 with the driving end of the engine 4 to complete the assembly of the engine 4 and the sampling device, open the fuel tank 5, add enough gasoline into it, and then The staff grabs the handle 6, lifts the engine 4 and places it on the upper wall of the supporting ring 3. The sampling end of the sampling device passes through the supporting ring 3 and reaches the ground. Then, the key cap is turned, and the threaded rod 8 rotates to push the clip 11 to get close to the sampling device, but not in contact with it, which plays a stabilizing and protective role for the rotating sampling device. After everything is ready, the engine 4 is started, the drill rod 12 rotates, and the lifting column 2 also slowly descends, and the drill bit enters the rock and soil layer. As it goes deeper, the soil continuously enters the sampling sleeve 14 through the gap of the sleeve, completing the sample collection. When the length is not enough or the lifting column 2 descends to the limit, the connection between the drill rod 12 and the engine 4 is released, and the new drill rod 12 is reused for superposition to increase the sampling length. After the sampling is completed, the lifting column 2 is used to drive the engine 4 to rise, the drill rod 12 is pulled out, and the sampling sleeve 14 is disassembled to obtain rock and soil samples, saving time and effort.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
