Abstract
An improved dry material sample collector is provided which allows a cross-section of conveyed bulk material to be intermittently sampled. A collection head, mounted upon the piston of a pneumatic cylinder, is extended into a bulk material conveying line at specific intervals. The pneumatic cylinder piston is of a hollow construction and provides a path through which the sample material flows. A piston guide, or a stabilizing arm, maintains the collection head perpendicular to the flow of conveyed material so that a homogenous sample is retrieved. Additionally, a pneumatic control system provides power to the pneumatic cylinder and allows the time interval between sampling operations to be varied, thereby controlling the amount of sample material obtained.
