[0002] Geological survey refers to all investigation work that takes geological phenomena (rocks, strata, structures, minerals, hydrogeology, landforms, etc.) as the object, is guided by geology and its related sciences, and is based on observation and research. In the process of investigating and sampling soil, it is necessary to sample the soil in order to cooperate with geological research work. Different geology presents different components and textures. Geology can be investigated and studied from these aspects. Therefore, geological sampling is particularly important.

[0025] Specifically, refer to Figure 2 One end of the sleeve 10 is fixedly connected to the outer side surface of the worm gear 9, and the end of the sleeve 10 away from the worm gear 9 passes through the interior of the limiting plate 6 and then extends to the outside of the limiting plate 6. A threaded rod 11 is installed inside the end of the sleeve 10 away from the worm gear 9. The inner side wall of the sleeve 10 is threadedly connected to the outer annular surface of the threaded rod 11, and the outer annular surface of the sleeve 10 is rotatably connected to the inner side of the limiting plate 6, thereby ensuring that the sleeve 10 is driven to rotate by the rotation of the worm gear 9. The rotation of the sleeve 10 causes its inner side wall to rotate along the outer annular surface of the threaded rod 11, driving the threaded rod 11 to move toward the end away from the worm gear 9, and the stability of the sleeve 10 during rotation is increased by the limiting plate 6.

[0026] Furthermore, one end of the worm 8 away from the servo motor 7 is rotationally connected to one side wall of the housing 1, one end of the worm wheel 9 is rotationally connected to the other side wall of the housing 1, and the worm 8 and the worm wheel 9 are meshed with each other, thereby ensuring that the worm 8 is driven to rotate by the servo motor 7 and the worm 8 synchronously drives the worm wheel 9 to rotate.

[0029] The working process of the utility model is as follows: using a sampling device for geological survey designed by the present invention, when the staff needs to take samples for geological survey, firstly, the device is placed vertically on the ground, and after the support plate 4 contacts the ground, the fixing rivet 5 is inserted into the ground to fix the device to the ground, so as to avoid deviation caused by displacement when sampling and rotating the soil, the handle 2 is held with both hands, and then the driving motor 14 is started, and the driving motor 14 drives the rotating shaft 15 to rotate and synchronously drives the spiral blade 16 to rotate, and then the servo motor 7 drives the worm 8 to rotate, and the worm 8 synchronously drives the worm wheel 9 to rotate, and the worm wheel 9 rotates to drive the sleeve 10 to rotate, and the sleeve 10 rotates so that the inner wall of the sleeve rotates along the outer ring surface of the threaded rod 11, driving the threaded rod 11 to move away from the threaded rod 11. One end of the worm gear 9 moves, and the stability of the sleeve 10 during rotation is increased by the limit plate 6. The movable block 12 is pushed to slide inside the connecting tube 3 by the threaded rod 11, thereby pushing the rotating shaft 15 to extend from the inside of the connecting tube 3 to rotate and sample the ground through the spiral blade 16. The limit bar 13 slides on the inner wall of the limit groove 302 to limit the sliding of the movable block 12 inside the connecting tube 3, so that the movable block 12 can slide stably inside the connecting tube 3. The sampling depth can be controlled by observing the sliding distance of the movable block 12 inside the connecting tube 3 through the transparent scale plate 301. After reaching the specified depth, the device can be picked up from the ground to sample the soil on the spiral blade 16. The operation is convenient to meet people's needs.
