[0024] Embodiment 1:

[0025] like Figures 1 to 3 As shown, this embodiment proposes a saline-alkali soil sampler, which mainly includes an outer cylinder 1, an inner column 4, a screw assembly 9 and a handle assembly 15, wherein handle portions 22 are fixedly connected to both sides of the top of the outer wall of the outer cylinder 1, and threads are arranged inside the handle portions 22, and a pedal assembly 2 is arranged at the outer bottom end of the outer cylinder 1. The pedal assembly 2 includes pedals 16 fixedly connected to the bottom ends of both sides of the outer wall of the outer cylinder 1, and a friction portion 17 is arranged at the top of the pedal 16. At the same time, the bottom end of the outer cylinder 1 is fixedly connected with an oblique insertion part 3, which is used to be inserted into the soil to make the overall stability of the equipment; by stepping on the pedal assembly 2, the outer cylinder 1 can be inserted into the soil through the oblique insertion part 3 to achieve the initial fixation of the outer cylinder 1. Then, the inner column 4 is threadedly connected to the inside of the outer cylinder 1, and its bottom end is fixedly connected with a connecting part 5. The bottom end of the connecting part 5 is provided with a sampling part 6, and the sampling part 6 includes a sampling cylinder 20 fixedly connected to the bottom end of the connecting part 5, and a sampling groove 21 is opened on one side of the sampling cylinder 20. A notch 7 is opened on the outer wall of the inner column 4, and a toothed ring 8 is fixedly connected to the top of the inner column 4;

[0026] The screwing assembly 9 is arranged above the inner column 4. By operating the screwing assembly 9, the inner column 4 can be rotated in the outer cylinder 1, thereby realizing the relative displacement of the inner column 4 with respect to the outer cylinder 1 and achieving the purpose of sampling. The handle assembly 15 is arranged at the top ends of both sides of the outer wall of the screwing cylinder 14, which includes a handle portion 18 fixedly connected to the top ends of both sides of the outer wall of the inner column 4. A friction portion 19 is arranged at the top end of the handle portion 18 for holding and controlling the rotation of the screwing cylinder 14.

[0027] Embodiment 2:

[0028] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0029] like Figure 4 As shown, this embodiment proposes a saline-alkali soil sampler, whose screwing assembly 9 includes a detachable screwing column 10 inserted into the top of the inner column 4, and a connecting block 11 is fixedly connected to the screwing column 10, and a plug-in shaft 12 is inserted into the connecting block 11. The plug-in shaft 12 is rotatably connected to a latch 13 that meshes with the gear ring 8, and the latch 13 can be moved. A screwing barrel 14 is fixedly connected to the top of the screwing column 10, and the screwing barrel 14 is slidably connected to the inner column 4 through a slot 7.

[0030] When in use, the user should first turn the latch tooth 13 counterclockwise to a suitable position, and then operate the screw barrel 14 to connect the screw column 10 to the top of the inner column 4, so that the latch tooth 13 is engaged with the gear ring 8. Subsequently, the user holds the handle portion 18 and rotates it clockwise, and then returns to the bottom and rotates it clockwise again. At this time, under the influence of the threaded connection, the inner column 4 moves downward inside the outer cylinder 1, and makes the sampling portion 6 approach the soil layer until the sample is obtained. Subsequently, the above steps can be reversed or the outer cylinder 1 can be directly pulled up to obtain a soil sample.

[0031] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown.
