[0038] Before the soil sampling device is actually used, the device needs to be adjusted according to the topography, soil conditions and sampling depth requirements of the sampling site.

[0039] First of all, the height of the device is adjusted, as shown in Figure 1 and Figure 2 , the support frame of the device is composed of a cross rod 1, a sleeve rod 5, a sleeve 6 and a support base, the cross rod 1 is installed at the upper end of the sleeve rod 5, the lower end of the sleeve rod 5 is slidably connected with the upper end of the sleeve 6, a threaded hole 13 is formed in one side of the upper end of the sleeve 6, a threaded bolt 14 is matched with the threaded hole 13, a plurality of positioning holes are uniformly distributed on the outer side of the sleeve rod 5 along the height direction, during adjustment, the threaded bolt 14 is loosened, the sleeve rod 5 slides up and down in the sleeve 6, after reaching the appropriate height, the threaded bolt 14 is tightened, the tip of the threaded bolt 14 is inserted into the corresponding positioning hole of the sleeve rod 5 through the threaded hole 13, so as to fix the position of the sleeve rod 5, thereby adjusting the height of the whole sampling device to meet the different sampling environments and operation requirements.

[0040] Then the device is fixed, as shown in Figure 2 , the support base includes a fixing ring 10, a plurality of support legs 11 and a taper rod 12, the fixing ring 10 is sleeved on the lower end of the sleeve 6, the plurality of support legs 11 are symmetrically arranged and installed on the outer periphery of the fixing ring 10, and the taper rod 12 is installed at the bottom of the fixing ring 10. After moving the device to the sampling site, the taper rod 12 is inserted into the soil, and the multi-point support structure formed by the taper rod 12 and the plurality of support legs 11 is used to enhance the stability of the device during sampling, and at the same time, the friction and grip between the support base and the ground are increased to prevent the device from shaking or toppling during work.

[0041] After the above preparation work is completed, the soil sampling operation can be carried out.

[0042] As shown in Figure 2As shown, the drive motor 3 is installed in the motor cylinder 2 at the end of the crossbar 1 away from the sleeve rod 5. The output shaft of the drive motor 3 passes through the lower end of the motor cylinder 2 and is fixed to the upper end of the drill rod assembly 4 through a coupling.

[0043] like Figure 3 As shown, the drill rod assembly 4 includes a threaded rod 41, a threaded cylinder rod 42, a fixed seat 43, a connecting seat 45, a soil-discharging drill rod 47, and a connecting rod 44. The upper end of the threaded rod 41 is connected to the output end of the drive motor 3, and the lower end is threadedly connected to the upper end of the threaded cylinder rod 42. The lower end of the threaded cylinder rod 42 is fixed to the upper end of the soil-discharging drill rod 47. The fixed seat 43 is installed on the upper end of the connecting frame 7 and is movably fitted on the threaded rod 41. The connecting seat 45 is installed on the outer periphery of the upper end of the threaded cylinder rod 42 and is slidably assembled with the inner side of the connecting frame 7. One end of the connecting rod 44 is installed on the outer side of the upper end of the sleeve 6 of the support frame, and the other end is rotatably fitted on the threaded rod 41 through the sleeve hole, which plays the role of auxiliary support for the threaded rod 41.

[0044] The drill bit 471 installed at the lower end of the soil discharge drill rod 47 has a square groove 472 for soil collection on its outer circumference. When the drill bit 471 drills into the soil, the soil enters the square groove 472. The upper end of the soil discharge drill rod 47 has a window groove 48 for soil discharge on its outer circumference. The window groove 48 has a soil discharge channel inside, and the upper and lower ends of the soil discharge channel are connected to the window groove 48 and the square groove 472, respectively.

[0045] During sampling, the drive motor 3 is started, and the drive motor 3 drives the threaded rod 41 to rotate. Since the threaded rod 41 is threadedly connected to the threaded cylinder rod 42, when the threaded rod 41 rotates, the threaded cylinder rod 42 will drive the soil discharge drill rod 47 and the drill bit 471 to rotate and drill downward into the soil under its action. During the drilling process, the slide 8 installed at the end of the connecting frame 7 away from the support frame plays a role.

[0046] like Figure 2 and Figure 3 As shown, the slide 8 consists of two parallel slides that are fixedly connected at their upper ends by a fixed seat 43. The inner sides of the two slides are provided with grooves 9. The connecting seat 45 is located between the two slides, and the sliders 46 installed on both sides of the connecting seat 45 are slidably located inside the adjacent grooves 9. This structure further ensures the stability of the drill rod assembly 4 during the lifting process.

[0047] After soil sampling is completed, the drive motor 3 is turned off, and the threaded rod 41 is rotated in the opposite direction, causing the threaded cylinder rod 42 to drive the soil discharge drill rod 47 and the drill bit 471 to rise and leave the soil. This completes the entire sampling operation. During the entire operation, all components work together to achieve efficient and stable soil sampling, meet the needs of soil sampling at different depths, and overcome the problems existing in the prior art.

[0048] The above merely describes a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto.
