Soil sampler and soil sampling method

Abstract

The present invention discloses a soil sampler and a soil sampling method. The soil sampler includes a frame, a moving sampling column, a driving mechanism, and a sealing assembly, where the moving sampling column is disposed at a bottom of the frame, and a bottom surface of the moving sampling column is of an inverted conical shape; the driving mechanism is fixedly arranged on the frame, and an output shaft of the driving mechanism is drivingly connected to a top end of the moving sampling column. During soil sampling, the driving mechanism drives the moving sampling column to move downward. The sealing assembly seals the material inlet port on the bottom surface of the moving sampling column, thereby eliminating the need for processing the surface soil. Subsequently, the sealing assembly is controlled to open the material inlet port, and the moving sampling column is driven to move downward continuously.
