ABSTRACT:
A device for periodically obtaining samples of particulate material from a moving belt comprising a sample cutter provided with an opening at one end, and means for moving said sample cutter across the moving belt and minimizing the effects resulting from disturbance of said material on the belt and maximizing the effective opening of the sample cutter by minimizing the amount of particulate material accumulating in front of the sample cutter as it moves across the moving belt, and means for minimizing the accumulation of particulate material on the side of the sample cutter positioned upstream of the movement of the particulate material on said moving belt.
