ABSTRACT:
A sampler having a pneumatically actuated scoop closes an opening in the bottom of a pipe containing an auger. The scoop swings through particulate material, (especially granular and/or powdered coal) as it is discharged from a belt of a feeder at the transition between where the coal is carried on the belt and where it falls over the end pulley around which the belt is entrained. The scoop extends across the full width of the belt and captures a sample of the material in the pipe where it is delivered by the auger to a discharge port. A valve connected to the discharge port maintains the pressure integrity of the feeder (at pressure above atmospheric pressure).
