Combined with different shock absorption, stabilization and deviation correction mechanisms, the device can adapt to different geological conditions and has strong versatility. This significantly improves its operating capabilities in a variety of environments and can cope with complex geotechnical structures.

[0016] 2. The present invention has the ability to quickly replace components: the equipment is designed with a quick replacement mechanism, so that the worn correction block can be quickly disassembled and replaced, reducing maintenance time and improving the working efficiency of the equipment.

[0017] 3. The present invention has efficient drilling performance: the drilling and extraction mechanism is combined with the design of the conical auger and the output motor, making the drilling process more efficient, and can quickly process the rock and soil and transport the cuttings to the central casing to ensure the continuity of the sampling process. Through the design of the drilling stabilization mechanism, the device can be deployed with the excavation depth during the drilling process, increasing the support area, thereby significantly improving the stability of the drilling. This design is particularly suitable for deep rock and soil areas, reducing the risk of tilting and instability of the equipment due to uneven geology. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the protrusion of the T-shaped docking column 39 added to the correction block 38 and inserted into the fixed T-shaped cylinder 41 also releases the restriction of the protrusion of the locking balls 45, so that the T-shaped docking column 39 can slide freely inside the fixed T-shaped cylinder 41.

As the central fixing mechanism 2, the deviation correction and shock absorption mechanism 3 and the drilling and extraction mechanism 5 are excavated into the rock formation along the external sleeve 1 At the same time, the drilling stabilization mechanism 6 also operates accordingly. The fixed sleeve 61 included in the drilling stabilization mechanism 6 is fixedly installed on the external sleeve 1, and the linkage disk 62 included in it is suspended on the fixed sleeve 61 and connected to the sealing sleeve 23 by means of the suspension arm 66 installed on the side wall, so that the linkage disk 62 moves along with the descent of the sealing sleeve 23. The side wall of the fixed sleeve 61 is provided with a support arm 63 in a circular distribution. At the same time, the outer ring side wall of the linkage disk 62 is provided with an auxiliary arm 64 in a circular distribution corresponding to the displacement of the support arm 63, and is hinged on the support arm 63. As the linkage disk 62 descends along with the sealing sleeve 23, it synchronously lifts the auxiliary arm 64 as a whole through the support arm 63, so that the auxiliary arm 64 is synchronously unfolded to both sides and supported on the soil ground of the drilling area. As the drilling depth increases, the unfolding range is expanded, the supporting area is increased, and the excavation shock absorption and deviation correction effect of the central fixing mechanism 2 and the deviation correction and deviation reduction mechanism 3 is cooperated, so that the deeper the excavation, the higher the support stability.

[0039] Embodiment 2 Please refer to the attached Figure 1 -Attached Fig.13 According to the above embodiment, this embodiment proposes a method for using a drilling sampling device for geotechnical engineering investigation, comprising the following steps: S1. The device performs soil and rock sampling operations in rock and soil areas. The overall device includes a central fixing mechanism 2 and a deviation correction and shock absorption mechanism 3 of a drilling main shaft structure installed on an external sleeve 1, and a drilling and material collection structure drilling and extraction mechanism 5. During drilling and extraction, the central fixing mechanism 2 and the deviation correction and shock absorption mechanism 3 will provide excavation shock absorption capabilities for the drilling and extraction mechanism 5. At the same time, the drilling stabilization mechanism 6 installed on the external sleeve 1 can be deployed and supported on the ground according to the excavation distance to improve the stability during excavation; S2, the center casing 21 fixes the drilling main shaft structure and excavates together, and the correction and damping mechanism 3 cooperates with the center fixing mechanism 2 to correct the drilling main shaft structure, the linkage slide 1 31 and the linkage slide 2 32 slide in two relative directions of the center casing 21 respectively, the sealing sleeve 1 22 and the limit sleeve 1 24 added to the center casing 21 directly limit the sliding distance and position of the linkage slide 1 31, the limit sleeve 25 and the rubber sleeve 26 directly limit the sliding distance and position of the linkage slide 2 32, and the linkage slide The one 31 is connected to the four sets of two-way rotating arms one 35 that can rotate through four sets of rotating shaft seats one 34 installed in an annular arrangement, and the linkage slide cylinder two 32 is connected to the four sets of two-way rotating arms two 37 that can rotate through four sets of rotating shaft seats two 36 installed in an annular arrangement. The four sets of two-way rotating arms two 37 are also connected to the two-way rotating arms one 35. The correction blocks 38 installed on all the two-way rotating arms one 35 and the two-way rotating arms two 37 directly contact the inner wall of the excavation slot hole, so as to correct the position of the drilling main shaft structure from four directions; S3. When the generated vibration is transmitted to the equipment, the T-shaped docking column 39 and the fixed two-way rotating arm 1 35 and two-way rotating arm 2 37 will be displaced, and the two-way rotating arm 1 35 and the two-way rotating arm 2 37 will perform relative rotational motion, and the two-way rotating arm 1 35 drives the linkage slide 1 31 to slide along the outer wall of the central sleeve 21 by rotating the installed rotating shaft seat 1 34, and the two-way rotating arm 2 37 drives the linkage slide 2 32 to slide along the outer wall of the central sleeve 21 by rotating the installed rotating shaft seat 2 36, and the retaining spring 1 33 installed inside the linkage slide 1 31 and the linkage slide 2 32 also compresses and deforms accordingly with the sliding displacement of the linkage slide 1 31 and the linkage slide 2 32 and the corresponding restrictions of the sealing sleeve 1 22, the limiting sleeve 1 24, the limiting sleeve 25 and the sealing sleeve 2 23, and cooperates with the moving linkage slide 2 32 and the linkage slide 1 31 to form a shock-absorbing and damping effect, so as to alleviate the vibration and improve the straightening ability of the equipment in a vibration environment; S4. When the correction block 38 is highly worn due to long-term use of the equipment, the correction block 38 can be quickly disassembled and replaced by using the quick-change mechanism 4 installed on the two-way rotating arm 1 35 and the two-way rotating arm 2 37. By manually toggling the pull-down cylinder 42 corresponding to each group of quick-change mechanism 4, the pull-down cylinder 42 slides toward the end direction of the fixed T-shaped cylinder 41. The sliding of the pull-down cylinder 42 also drives the installed retaining spring 2 43 to compress and deform. When the pull-down cylinder 42 slides, the release groove 46 installed on it docks with the multiple groups of limiting conical holes 44 installed on the fixed T-shaped cylinder 41, and the pull-down cylinder 42 also breaks away from the compacted contact with the locking balls 45 sliding inside the limiting conical holes 44, so that each group of locking balls 45 can slide inside the corresponding limiting conical holes 44. At this time, the protrusion of the T-shaped docking column 39 installed on the correction block 38 and inserted into the fixed T-shaped cylinder 41 also releases the protrusion of the locking balls 45 The restriction of the outgoing part enables the T-shaped docking post 39 to slide freely inside the fixed T-shaped cylinder 41, so that the correcting block 38 and the T-shaped docking post 39 can be taken out, and the correcting block 38 in good condition can be replaced for installation, and the corresponding T-shaped docking post 39 is inserted into the fixed T-shaped cylinder 41, and the lower end protrusion of the T-shaped docking post 39 extends below the locking ball 45, and at the same time, the held lower pull-down cylinder 42 is released, and the deformed and compressed retaining spring 2 43 causes the lower pull-down cylinder 42 to slide upward along the fixed T-shaped cylinder 41, and the release groove 46 immediately disengages from each group of limiting conical holes 44, and the lower pull-down cylinder 42 then presses each group of locking balls 45 into the limiting conical holes 44, and the locking balls 45 extend through the limiting conical holes 44 to the protrusions in the fixed T-shaped cylinder 41, which will also restrict the T-shaped docking post 39 in the fixed T-shaped cylinder 41, and the correcting block 38 corresponding to the T-shaped docking post 39 is also fixed, thereby realizing the ability of quick disassembly and replacement; S5. The conical auger 51 included in the drilling and extraction mechanism 5 is a drill bit structure for contacting the ground and drilling. Its surface has a spiral drilling socket. The linkage spindle 52 installed on its rotating shaft extends into the central sleeve 21 and extends into the external sleeve 1. The output motor 55 driving the conical auger 51 and the linkage spindle 52 to rotate is installed in the external sleeve 1 and is clamped and displaced inside the external sleeve 1 through the circular chuck on the output motor 55. At the same time, the advance tank 53 included in the drilling and extraction mechanism 5 is also fixed on the external sleeve 1 and extends into the central sleeve 21. An advance tank 53 is installed inside the advance tank 53 and rotates with the linkage main shaft 52. When the output motor 55 drives the advance tank 53, the linkage main shaft 52 and the conical auger 51 to rotate, the drilling stabilization mechanism 6 generates a downward thrust to push the center fixing mechanism 2, the deviation correction and shock absorption mechanism 3, the quick replacement mechanism 4 and the drilling and extraction mechanism 5 to start descending along the inner wall of the external sleeve 1, so that the conical auger 51 included in the drilling and extraction mechanism 5 drills into the rock and soil area, and at the same time, the debris generated by the excavation begins to enter the center casing 21 along the spiral chute of the conical auger 51; S6. As the central fixing mechanism 2, the deviation correction and shock absorbing mechanism 3 and the drilling and extraction mechanism 5 are excavated into the rock formation along the external sleeve 1, the drilling stabilization mechanism 6 also operates accordingly. The fixed sleeve 61 included in the drilling stabilization mechanism 6 is fixedly installed on the external sleeve 1, and the linkage disk 62 included in the fixed sleeve 61 is suspended on the fixed sleeve 61 and connected to the sealing sleeve 23 by the suspension arm 66 installed on the side wall, so that the linkage disk 62 moves with the descent of the sealing sleeve 23. The side wall of the fixed sleeve 61 is equipped with support arms 63 in a circumferential distribution. At the same time, the linkage disk The auxiliary arm 64 is also installed in the form of a circular distribution on the outer ring side wall corresponding to the displacement of the support arm 63, and is hinged on the support arm 63. Then the linkage plate 62 follows the sealing sleeve 23 to descend, and it lifts the auxiliary arm 64 as a whole synchronously through the support arm 63, so that the auxiliary arm 64 is synchronously deployed to both sides and supported on the soil ground in the drilling area. With the increase of drilling depth, the deployment range is expanded and the support area is increased. In combination with the excavation shock absorption and deviation correction effect of the central fixing mechanism 2 and the deviation correction and deviation reduction mechanism 3, the deeper the excavation, the higher the support stability.
