Cast auger gating interface

摘要

The auger includes a first cast section and a second cast section. The first cast section includes a first flight having a gate projection that remains on the first flight after a gate which is used during casting the first cast section has been removed from the first cast section. The second cast section includes a second flight having a recess that receives the gate projection when the first flight is coupled to the second flight such that the gate projection does not need to be ground off in order to attach the first cast section to the second cast section. The first flight is attached with the second flight to create a substantially smooth and unbroken transition between the first flight and the second flight such that the auger efficiently transports paving material from the hopper of a road paving machine onto a prepared road bed.
