[0054] During the rotation of the rotating plate 709, the guide plate 713 can be driven to move synchronously, and the inclined surface on the guide plate 713 can be driven to contact the fixed frame 701. At this time, under the guiding action of the inclined surface of the guide plate 713, the fixed frame 701 can push the guide plate 713 to automatically move toward the inside of the gas storage frame 710. Under the movement of the guide plate 713, the first piston 712 can push the air in the gas storage frame 710 through the air guide pipe 717 to the plug tube 718. At this time, under the action of air pressure, the air can push the second piston 720 in the plug tube 718 to move outward automatically, and combined with the plug rod 721, the extension plate 715 can be pushed to move outward automatically. At this time, under the self-extension action of the extension plates 715 on both sides, combined with the bottom plate 714, the support area can be effectively increased, and the overall placement stability of the device can be further improved, thereby ensuring the stability and safety of the subsequent working state of the sampling device.

[0055] Then the staff can drive the third hydraulic rod 16 and the third servo motor 18. Under the driving action of the third servo motor 18, the auger rod 19 can be driven to rotate stably, and the auger rod 19 can be pushed downward at a uniform speed through the third hydraulic rod 16, so that the rock formation can be stably drilled. After the drilling is completed, the auger rod 19 can be driven to move upward and reset through the third hydraulic rod 16. At this time, the staff only needs to pull the connecting plate 14 upward to drive the clamping rods 15 on both sides to move out of the corresponding clamping grooves 11. At this time, the supporting plate 8 can be driven to rotate 180° through the rotating rod 10 to complete the position switching of the auger rod 19 and the connecting net frame 903. Then the connecting plate 14 can be loosened. At this time, under the elastic action of the reset spring 13, the clamping rods 15 on both sides of the connecting plate 14 can be driven to move downward and engage in the clamping grooves 11 on both sides of the supporting plate 8 to ensure that the auger rod 19 and the connecting net frame 903 are engaged and fixed after the position switching.

[0056] After the position of the auger rod 19 and the connecting mesh frame 903 is switched, the connecting mesh frame 903 can be automatically inserted into the sampling pit drilled by the auger rod 19 by the first hydraulic rod 901. Subsequently, the second servo motor 905 and the drive motor 912 are driven. At this time, the second servo motor 905 can drive each group of first bevel gears 907 to rotate simultaneously through the drive shaft 906. Under the rotation of the first bevel gears 907, the second bevel gears 908 connected by meshing can drive the second threaded rod 909 to rotate stably. At this time, under the stable rotation of the second threaded rod 909, the connecting plate 910 connected by threads can push the first connecting cylinder 911 and the second connecting cylinder 914 through the first through groove 904 on the connecting mesh frame 903 and contact the inner wall of the sampling pit.

[0057] Meanwhile, under the driving action of the drive motor 912, the second connecting cylinder 914 on the turntable 913 can be driven to rotate stably through the output shaft. At this time, the second connecting cylinder 914 can drive each connecting shaft 915 inside to revolve inside the first connecting cylinder 911, and then can drive the circular gears 916 on the connecting shafts 915 to revolve on the internal gears 917. At this time, under the meshing drive of the circular gears 916 and the internal gears 917, each connecting shaft 915 in the revolving process can be driven to rotate automatically, and then each first drill bit 918 can be driven to rotate synchronously. At this time, under the movement of the second connecting cylinder 914 and the rotation of each first drill bit 918, the rock on the inner wall of the rock formation can be cut and drilled. Subsequently, during the continuous rotation of the second connecting cylinder 914, the second drill bits 921 are driven by each second hydraulic rod 920 to move towards the middle inside the second connecting cylinder 914, and then the rock samples can be automatically cut off. At this time, the rock samples can be blocked by each second hydraulic rod 920 and collected into the second connecting cylinder 914 to complete the sampling work. At this time, under the action of the second connecting cylinders 914 at different depths, the sampling work of rock samples at different depths can be carried out simultaneously, and under the combined action of two second connecting cylinders 914 at the same depth, sampling at different points at the same depth can be carried out simultaneously, avoiding the influence of single samples on the accuracy of subsequent detection and analysis results.

[0058] After the sampling work is completed, only by driving the drive shaft 906 to rotate in the reverse direction by the second servo motor 905, the second threaded rod 909 can be driven to rotate in the reverse direction through the first bevel gear 907 and the second bevel gear 908. Then, the first connecting cylinder 911 and the second connecting cylinder 914 can be driven to move automatically into the connecting mesh frame 903 through the connecting plate 910 to complete the storage. Subsequently, the connecting mesh frame 903 can be driven to move upward and reset by the first hydraulic rod 901. Then, when the staff takes the rock samples, only by repeating the above operations, driving the second connecting cylinder 914 to extend can the rock samples be taken.

[0059] Before the sampling device starts working, the staff can drive the adjusting frame 3 to move stably on the fixing plate 2 by rotating the first threaded rod 4 on the adjusting frame 3, and then can conveniently adjust the supporting position of the automatic supporting assembly 7 at the bottom of the supporting plate 5 according to the actual environment; and after the sampling device is finished working, it is only necessary to drive the first coil 706 on the output shaft of the first servo motor 705 to rotate in the opposite direction and unwind the traction rope 707. At this time, under the elastic action of the volute spring 703, the driven shaft 704 can be driven to automatically reverse and reset, and the driven shaft 704 can rewind the traction rope 707 through the second coil 708, so that the traction rope 707 can be reeled in later. The operation is repeated continuously, and under the reverse reset action of the driven shaft 704, the bottom plate 714 can be driven to leave the ground, while the universal wheel 723 is in contact with the ground, so as to ensure the stability and convenience of the subsequent moving state. Moreover, when the driven shaft 704 drives the rotating plate 709 to reverse and reset, the rotating plate 709 can drive the guide plate 713 to move away from the fixed frame 701. After the guide plate 713 loses the obstruction, the first connecting spring 711 can push the first piston 712 and the guide plate 713 to automatically move outward and reset. Similarly, under the elastic action of the second connecting spring 719, the plug rod 721 on the second piston 720 can drive the extension plate 715 to move and reset, thereby completing the automatic storage.
