The sampling cylinder 3 is threadedly connected to the outer wall of the hollow shaft 2 and coaxially arranged with the hollow shaft 2, and rotates under the driving of the hollow shaft 2. The spline sleeve 4 is installed inside the hollow shaft 2, and the spline shaft 5 is slidably arranged in the spline sleeve 4. Through the design of the spline sleeve 4, the hollow shaft 2 can drive the spline shaft 5 to rotate, and the spline shaft 5 can slide relative to the hollow shaft 2. The piston 6 is slidably installed inside the sampling cylinder 3 and threadedly connected to the bottom end of the spline shaft 5, and slides relative to the sampling cylinder 3 under the driving of the spline shaft 5. The first linear slide 7 is installed on the first support plate 1 along the axial direction of the hollow shaft 2 and is used to provide driving force to realize linear movement.

The top end of the spline shaft 5 is rotatably installed on the second support plate 8, and the two can rotate relative to each other to avoid the second support plate 8 from rotating with the spline shaft 5. The hollow shaft 2 can be controlled to rotate to drive the sampling cylinder 3 to rotate.

[0038] The soil sampling device provided by the embodiment of the present disclosure can drive the sampling cylinder 3 to rotate after the hollow shaft 2 rotates under the driving of external force. Then, the first support plate 1 is held and pressed downward to be inserted into the ground, so that the soil is collected in the sampling cylinder 3. Then, the first support plate 1 is held and lifted upward to be pulled out of the ground. Finally, the first linear slide 7 is controlled to work to drive the second support plate 8 to move, further drive the hollow shaft 2 to move, and finally drive the piston 6 to slide in the sampling cylinder 3. Thus, the soil in the sampling cylinder 3 is pushed out to complete the sampling work. Compared with the manual pulling mode, time and labor are saved. Since the sampling cylinder 3 and the hollow shaft 2 are threadedly connected, and the piston 6 and the spline shaft 5 are threadedly connected, the device has the advantages of being easy to disassemble and convenient to replace the sampling cylinder 3 and the piston 6 of different sizes. In addition, through the design of the spline sleeve 4, the spline shaft 5 can rotate with the hollow shaft 2. Further, the piston 6 can rotate with the sampling cylinder 3, thereby reducing the wear between the piston 6 and the sampling cylinder 3.

[0040] In the embodiments of the present disclosure, the electric push rod 12 is controlled to work, and under the pulling or pushing of the electric push rod 12, the third support plate 10 can be flipped relative to the trolley 9. Finally, the position of the sampling cylinder 3 can be adjusted to make the sampling be in a horizontal or vertical state. When the sampling cylinder 3 is in the horizontal state, the longitudinal space occupation of the device can be reduced. When the sampling cylinder 3 is in the vertical state, the sampling work can be carried out. During the sampling process, the second linear slide 11 is controlled to work, which can drive the third support plate 10 to move, and finally realize the automatic movement function of the sampling cylinder 3.
