Soil sampling device and sampling method for agricultural ecological environment monitoring

The invention provides a soil sampling device for agricultural ecological environment monitoring and a sampling method, and relates to the technical field of soil sampling. The mounting supporting part is rotationally connected with a driving supporting part; a lifting point finding part is connected to the driving supporting part in a sliding manner; the lifting point finding part is connected with a sampling device in a sliding manner; the sampling device is sleeved with a drilling crushing part; the mounting supporting part is fixedly connected with a collection plugging piece; a shallow sampling piece is fixedly connected to the collection plugging piece, so that drilling sampling is assisted, soil cannot be extruded, the device is more suitable for deep gravel soil, automatic sealing and sampling storage can be assisted, and the problems that according to an existing soil sampling device for agricultural ecological environment monitoring, sampling depends on impact sampling, and the sampling efficiency i
