Patent ID: 8746439

Claim:
A feed auger assembly for conveying particular material in a longitudinal direction, the feed auger assembly comprising: a first auger housing extending in the longitudinal direction from an inlet end to a respective discharge end; a first auger flight rotatably supported in the first auger housing so as to be arranged to convey the particulate material from the inlet end to the discharge end; a second auger housing extending in the longitudinal direction from an intermediate end to an outlet end; the first auger housing being concentrically received within the second auger housing so as to define an annular space between the first auger housing and the second auger housing which extends in the longitudinal direction; a second auger flight rotatably supported in the second auger housing within said annular space between the first auger housing and the second auger housing so as to be arranged to convey the particulate material longitudinally through the annular space towards the outlet end; the discharge end of the first auger housing being arranged to discharge into the annular space between the intermediate end and the outlet end of the second auger housing; and the first auger housing being longitudinally slidable relative to the second auger housing in the longitudinal direction such that a distance between the inlet end of first auger housing and the outlet end of the second auger housing is adjustable.
