ABSTRACT:
The present invention is a soil sampling probe where a conical piston is kept at the opening to the sampling container by a first threaded portion near the top of the piston rod which engages a threaded opening near the top end of the container. With the piston in this position the probe is more streamlined to reduce the required driving force. When the desired depth is reached, the piston rod is rotated until the first threaded portion of the piston rod is disengaged from the threaded opening at the top end of the container. The piston is then raised until a second threaded portion of the piston rod, near the piston itself, engages a threaded lock ring near the top end of the container. Thus the piston is locked in place near the top of the container. The container is then further inserted to take the core sample.
