[0013] 2. The soil sampling device for agricultural soil testing is provided with a threaded rod, a connecting plate, a threaded barrel, and a pocket block. When the pocket block is installed through a slider, turning the handle can drive the auger roller at the bottom to rotate, sampling the soil and delivering it upward. The distance between the connecting plates allows the sample to enter the pocket block, facilitating subsequent collection and transportation. In addition, the threaded barrel supports the turning handle, which drives the threaded rod to rotate and descend at the same time, allowing the auger roller to deliver the required soil sample. This facilitates operation while optimizing the inconvenience of carrying batteries. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a soil sampling device for agricultural soil testing, comprising a mounting tube 1, three support assemblies 2 are fixedly mounted on the outside of the mounting tube 1, the support assembly 2 comprises a support 1 201, a rocker 202 is hinged on one side of the support 1 201 through a pin shaft, a support rod 203 is provided at the other end of the rocker 202, a positioning block 3 is installed in the support rod 203, a guide groove 4 is provided in the support rod 203, the guide groove 4 is slidably connected to the positioning block 3, and the guide groove 4 plays a role of supporting and limiting the movement of the positioning block 3, so as to facilitate the control of the positioning block 3 to slide to a fixed position.

[0021] The top of the support rod 203 is hinged with a support 205 through a pin shaft. A positioning hole 204 is respectively opened on the same side of the support rod 203 and the positioning block 3. There are several positioning holes 204 on both sides of the support rod 203. By providing the positioning holes 204, the positioning block 3 is moved to the point to be fixed. By positioning the positioning holes 204, the operator can easily fix it, so that the support rod 203 is against the ground to support the device;

[0022] The internal thread of the positioning hole 204 is connected to a positioning bolt 5, and one end of the positioning bolt 5 is threadedly connected to a nut 6. A protective washer 7 is provided between the nut 6 and the support rod 203. By providing the protective washer 7, the positioning block 3 can be limited by inserting the positioning bolt 5 and rotating the nut 6. The protective washer 7 can reinforce the locking of the nut 6 and protect the outside of the support rod 203, thereby extending the service life of the device.

[0023] One side of the support 205 is fixedly connected to the outer side of the mounting tube 1, and several connecting plates 8 are fixedly installed on the top of the mounting tube 1. The same connecting tube 9 is fixedly installed on the top of the several connecting plates 8. A slider 11 is fixedly installed on the outer side of the connecting tube 9, and a limiting plate 12 is fixedly installed on the bottom of the slider 11. By providing the limiting plate 12, the pocket block 10 can be disassembled through the slider 11, which is convenient for carrying and sampling. The limiting plate 12 can resist the protrusion on the top of the through groove 13 to prevent the pocket block 10 from falling and causing an accident.

[0024] A pocket block 10 is provided on the outside of the connecting tube 9, and a threaded tube 15 is fixedly installed inside the connecting tube 9. A threaded rod 16 is threadedly connected to the threaded tube 15, a turning handle 17 is fixedly installed on the top of the threaded rod 16, and an auger roller 18 is fixedly installed on the bottom of the threaded rod 16. A through groove 13 is provided on the outside of the pocket block 10 at the position corresponding to the limit plate 12, and a slide groove 14 is provided in the through groove 13. The slide groove 14 is slidably connected to the slider 11. By providing the slide groove 14, the slide groove 14 can limit the movement of the slider 11, so that the pocket block 10 can be hung vertically and stably on the device.

[0025] The working principle of this utility model is:

[0026] After placing the device in the working position, lift the rocker 202 by external force so that it can drive the positioning block 3 to slide in the guide groove 4, so that the support rod 203 can select the angle of expansion and the height of the initial operation. Then, insert the positioning bolt 5 into the positioning hole 204 so that it can slide out from the positioning hole 204 at the other end of the support rod 203. Then, insert the protective washer 7 and rotate the nut 6 so that the positioning bolt 5 fixes the sliding of the positioning block 3. Before reaching the required sample, turn the handle 17 so that it can drive the auger roller 18 at the bottom to rotate, so as to dig the soil and deliver it upward. The useless soil samples are dug out through the gap between the connecting plates 8, and then the pocket block 10 can be quickly installed on the mounting tube 1 by sliding between the slider 11 and the slide groove 14, and the limit plate 12 can be used to support the protrusion on the top of the through groove 13. When the pocket block 10 is installed through the slider 11, the distance between the connecting plates 8 allows the sample to enter the pocket block 10. In addition, the support of the threaded tube 15 allows the handle 17 to rotate and drive the threaded rod 16 to rotate while allowing it to descend, so that the auger roller 18 can deliver the required soil sample, and the agricultural soil sampling can be completed.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
