Claim:
1. An auger transfer conveyor apparatus for granular material, the apparatus comprising: a conveyor body defined by right and left side walls, a front wall, and a floor comprising a substantially horizontally oriented front floor section and an upward and rearward sloping rear floor section; a plurality of substantially parallel auger assemblies, each auger assembly comprising a substantially horizontal auger section extending along the front floor section, an inclined auger section extending along the sloping rear floor section to a transfer discharge at a top edge of the rear floor section, and a flexible joint connecting the horizontal auger section to the inclined auger section; wherein the auger assemblies are open such that during operation granular material moves from the front wall toward the transfer discharge above and between the auger assemblies; an auger drive operative to rotate the auger assemblies; wherein each horizontal auger section has a horizontal auger shaft and a horizontal auger flight extending from the horizontal auger shaft, wherein the horizontal auger flight has a horizontal auger flight diameter, and each inclined auger section has an inclined auger shaft and an inclined auger flight extending from the inclined auger shaft, wherein the inclined auger flight has an inclined auger flight diameter, and wherein the inclined auger flight diameter is greater than the horizontal auger flight diameter.
