Soil sampling device based on new energy power supply

The invention provides a soil sampling device based on new energy power supply, which belongs to the technical field of soil sampling and comprises a support frame, a sampling barrel, a rotating shaft, a drill bit, a soil scraping plate assembly and an elastic reset part. According to the soil sampling device based on new energy power supply, when the sampling barrel descends to a preset position, the soil scraping plate assembly moves outwards under the action of centrifugal force and is gradually inserted into the side wall of the sampling hole, and the soil scraping plate assembly scrapes soil needing to be sampled into the soil collecting cavity while rotating along with the sampling barrel. After sampling is completed, the centrifugal force of the soil scraping plate assembly is reduced by reducing the rotating speed of the sampling barrel, and the soil scraping plate assembly is reset under the action of the elastic reset piece, so that the soil scraping plate assembly reversely moves into the soil coll
