ABSTRACT:
A sealed housing having entrance and exit ports at its upper and lower surfaces for connection into a vertically extending gravity spout, with a collecting head mounted within the housing for swinging movement across the central flow passage extending from the entrance port to the exit port. The collecting head has an elongate opening confronting the entrance port, such that particulate matter flowing through the housing will be collected within the interior of the collecting head and passed out of the housing through a discharge tube, for sampling. Rotary air cylinders disposed on top of the sealed housing adjacent the entrance port effect swinging movement of the collecting head about an axis parallel to that of the central flow passage, such that the collecting head passes entirely through the particulate flow, from one side of the product stream to the other, thereby assuring a representative sample.
