摘要： Apparatus for taking soil samples that includes a drive head attachable to the drill rod of a drill rig having a drive hammer, a sample receiving barrel of longitudinally split barrel sections having a reduced diameter end portions extended into the drive head, one of the sections being pinned to the drive head, and a drive shoe threaded on the other end portions of the barrel sections. When the drive shoe is removed, the unpinned barrel section is hingedly movable relative the other barrel section.
