Sampling device for soil environment detection

The invention relates to the technical field of detection devices, in particular to a sampling device for soil environment detection, which comprises a sampling rod, a positioning assembly and a driving assembly, under the action of the positioning assembly, the sampling rod is always in a vertical state, a sampling head arranged at the lower end of the sampling rod can sample soil, and the sampling accuracy is ensured. If the lower end of the sampling head is in contact with hard soil, the downward moving resistance of the sampling head is increased, the deformation quantity of the first elastic piece is increased along with rotation of the driving disc, and the downward positive pressure provided by the first elastic piece for the sampling rod is increased. If the lower end of the sampling head is in contact with soft soil, the downward moving resistance of the sampling head is reduced, the deformation quantity of the first elastic piece is reduced along with rotation of the driving disc, and the downward p
