Soil sampling device

The invention discloses a soil sampling device, relates to the technical field of soil sampling, and aims to solve the problems that a sampler can be continuously inserted into middle-layer soil only by using a large force of a sampler, and the workload is large when the sampler is inserted into the middle-layer soil. The sampling device comprises a vertical rod, a sampling tube connected to the bottom of the vertical rod and a handle connected to the top of the vertical rod, the vertical rod is sleeved with a support, the peripheral side of the support is provided with at least three supporting legs used for supporting the support, the supporting legs are obliquely arranged towards the side away from the vertical rod, the vertical rod is sleeved with a power-assisted sleeve, and the vertical rod is provided with a threaded part for threaded connection of the power-assisted sleeve. The threaded part is used for enabling the power-assisted sleeve to move in the direction close to or away from the sampling pipe
