[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-2 The utility model provides an embodiment: a drilling sampling device, including a base 1, a fixed block 2 is fixedly connected to the top of the base 1, a threaded rod 4 is rotatably connected inside the fixed block 2, a motor 5 is fixedly connected to the top of the base 1, a cam 2 6 is fixedly connected to the output end of the motor 5, a cam 1 3 is fixedly connected to one end of the threaded rod 4, a belt 7 is arranged between the cam 1 3 and the cam 2 6, an L-shaped support rod 10 is rotatably connected to the top of the base 1, an adjustment plate 9 is rotatably connected to one end of the L-shaped support rod 10, a drilling device 11 is arranged on the top of the adjustment plate 9, a sleeve 8 is threadedly connected to the outer wall of the threaded rod 4, and one side of the adjustment plate 9 is rotatably connected to the outer wall of the sleeve 8;

[0031] Specifically, in order to adjust the expansion angle of the plate 9, we need the output end of the motor 5 to drive the cam 2 6 to rotate. When the cam 2 6 rotates, it will drive the cam 1 3 to rotate through the belt 7. Then, the cam 1 3 drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, it will drive the adjustment plate 9 to be supported through the sleeve 8. Since the middle part of the adjustment plate 9 is connected to the base 1 through the L-shaped support rod 10, the adjustment plate 9 will adjust the support angle of the adjustment plate 9 through the movement of the sleeve 8. This adjustment process is dynamic and can be adjusted as needed. When the support angle of the adjustment plate 9 changes, it will also drive the drilling device 11 to perform corresponding actions. The design and function of the drilling device 11 is to perform drilling operations at the location where drilling is required. Therefore, the adjustment angle of the adjustment plate 9 has an important influence on the working efficiency and drilling quality of the drilling device 11.

[0032] Reference Figure 3-4 A connecting plate 12 is fixedly connected to one side of the base 1, and a limiting assembly is arranged inside the connecting plate 12. The limiting assembly includes a limiting plate 14 and a connecting column 13. One end of the connecting column 13 is fixedly connected to the top of the limiting plate 14, and the outer wall of the limiting plate 14 is slidably connected to the inside of the connecting plate 12. A cone 15 is fixedly connected to the bottom of the limiting plate 14, and a slide groove 16 is provided inside the cone 15. A limiting column 17 is fixedly connected inside the cone 15, and a connecting plate 2 18 is slidably connected to the outer wall of the limiting column 17. The outer wall of the connecting plate 2 18 is rotatably connected to a connecting rod 21, and the outer wall of the connecting rod 21 is slidably connected to the inside of the slide groove 16. A card 19 is rotatably connected to one end of the cone 15, and the bottom of the card 19 is rotatably connected to the outer wall of the cone 15. A strong spring 20 is sleeved on the outer wall of the limiting column 17, and one end of the strong spring 20 is fixedly connected to the inside of the cone 15, and the other end of the strong spring 20 is fixedly connected to the top of the connecting plate 2 18;

[0033] Specifically, first, the base 1 is placed at the position where drilling is required, and then the connecting column 13 is removed, and the cone 15 is driven to be inserted into the soil through the connecting column 13. Since the card 19 is not blocked by the connecting plate 12, the card 19 supports the connecting plate 2 18 through the tension of the strong spring 20. This support method enables the connecting plate 2 18 to drive the card 19 to unfold through the connecting rod 21, thereby fixing the base 1. This process is not only simple and easy, but also can effectively fix the base. The design of the connecting column 13 is clever, which can drive the cone 15 to be inserted into the soil, making the base more stable. The combination of the card 19 and the strong spring 20 enables the connecting plate 2 18 to stably support the base 1. This design not only improves the efficiency of drilling, but also ensures the quality of drilling.

[0034] Working principle: when using the drilling sampling device, first place the base 1 at the position where drilling is required, then remove the connecting column 13, and drive the cone 15 to be inserted into the soil through the connecting column 13. Since the card 19 is not blocked by the connecting plate 12, the card 19 supports the connecting plate 2 18 through the tension of the strong spring 20, so that the connecting plate 2 18 drives the card 19 to unfold through the connecting rod 21, so that the card 19 unfolds in the soil to increase the contact area and forms a barb shape, thereby fixing the base 1. Then, it is necessary to adjust the unfolding angle of the adjustment plate 9. The output end of the motor 5 drives the cam 2 6 to rotate, and the cam 2 6 drives the cam 1 3 to rotate through the belt 7, and the cam 1 3 drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, the adjustment plate 9 is driven to be supported through the sleeve 8. Since the middle part of the adjustment plate 9 is connected to the base 1 through the L-shaped support rod 10, the adjustment plate 9 will adjust the support angle of the adjustment plate 9 through the movement of the sleeve 8, thereby driving the drilling device 11, and drilling is performed through the drilling device 11.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
