Soil sampling device

The utility model relates to the technical field of soil quality detection, and discloses a soil sampling device which comprises a right stand column, a clamping groove is formed in one side of the right stand column, a connecting groove located on one side of the clamping groove is formed in the other side of the right stand column, a handle is arranged above the right stand column, and a leaf connecting rod is arranged in the connecting groove. The soil sampling device has the beneficial effects that the connecting rod is movably connected with the clamping groove, so that an appropriate limiting ring or limiting assembly is selected to be mounted between the right stand column and the left stand column according to the size of a sampling rod, and then the sampling rod sequentially penetrates through the two limiting rings to be inserted into soil; then a motor is controlled to make the sampling rod go deep into the soil for sampling, at the moment, the two limiting rings can limit the sampling rod, the sam
