ABSTRACT:
An improved auger airlock is disclosed which includes a blade for preventing blockage or buildup of material conveyed through the airlock. An axially rotatable auger blade is disposed within the elongated auger tube and has a central shaft extending to the outlet end of the tube. An elongated blade is secured to the end of the shaft, transversely of the longitudinal axis thereof, for rotation with the shaft. The blade is operable for cutting up agglomerated material at the outlet end to prevent clogging. A hingeably mounted door is attached to the outlet of the tube and is biased to the closed position by an adjustable counterweight operably attached to the door.
