ABSTRACT:
Apparatus for feeding wood chips and the like into a treatment bin includes a feed tube assembly adapted to lead into the bin at a non-zero angle relative to the horizon. A plate is supported underneath the lower end of the feed tube assembly to collect in a mound wood chips fed through the feed tube. The height of the lower end of the feed tube assembly is adjusted so that the lower end of the feed tube assembly engages the mound of wood chips and thereby forms a seal with the mound. A plow is supported between the plate and the lower end of the feed tube assembly. Either the plate is stationary and the plow rotates or the plow is stationary and the plate rotates to knock wood whips from the mound off the plate. The apparatus optionally includes a feed screw mounted within and longitudinally of the feed tube assembly to compress the wood chips into the mound.
