ABSTRACT:
An apparatus for sampling particulate material, such as wood chips as they fall through an unloading chute, includes a tube mounted in a wall of the chute and having an upper end extending into the path of chip flow. The upper end includes a generally semi-cylindrical extension terminating in a generally quarter-spherical section in provision of a chip receiving opening to one side of the tube and a chip deflector to the opposite side of the tube. The lower end of the tube extends outside the chute and communicates with a chip-collecting container, and the tube is selectively rotatable by a timed motor and gear arrangement to present the one side of the tube upwardly to receive chips for sampling or the other side upwardly to deflect chips and prevent their entry into the tube for collection in the chip container.
