Abstract
An auger compactor is described in which a hopper is provided to feed vegetation into the intake end of a compression chamber which leads from the intake end opening into the hopper to a discharge end. A first helical auger flight extends along an auger axis, of a pitch that diminishes from a maximum pitch adjacent the intake end of the compression chamber to a minimum pitch adjacent the discharge end. A second helical auger flight is also situated within the compression chamber, circumscribing and slidably supporting the first helical auger flight. The second auger flight includes a second helical pitch that also diminishes from a point adjacent the intake end of the compression chamber to a point adjacent the discharge end of the compression chamber. A drive is provided to rotate one of the flights about the auger axis, to move and compact vegetation along a flow path from the hopper through the discharge end of the compression chamber. An over-compression chamber opening into the discharge end of the compression chamber, with a compression bulkhead positioned normal to the auger axis. An over-compression member faces the compression bulkhead across the over-compression chamber a…
