Abstract
The soil sampler device has a cylindrical tubular shaped body member, one end portion of which is formed into a soil receiving section comprised of a pair of transversely opposite semicylindrically shaped half members one of which is integral with the body member and the other of which is cut from the body member for movable support thereon into and out of a cylinder forming relation with the integral or stationary half member. The movable member is guided into the cylinder forming relation with the stationary member on ground insertion of the device and such relation is maintained by the pressure applied on a footrest projected laterally from the movable member. An inlet opening of reduced diameter for the soil receiving section provides for a friction free travel of the soil sample material throughout the length of such section, with the sample being removed for testing by merely being dropped from the stationary member when the movable member is out of the cylinder forming relation.
