Abstract
A device for sampling soil of tropical lowland rainforest is provided, and the device includes a driving motor, a probe rod and a sampling barrel. An output shaft of the driving motor is fixedly connected with the top end of the probe rod. The probe rod is hollow. The sampling barrel is disposed in the probe rod. An opening of the bottom end of the sampling barrel faces to the soil inlet. Two baffle plates are also arranged in the probe rod. The side wall of the baffle plate is arc-shaped, and the bottom end of the baffle plate is semicircular. The semicircular baffle plates can pass through the space and can be joined to form a cylinder with a closed bottom end. Two linear motors are fixedly arranged in the probe rod and can respectively drive the two baffle plates to move.
