Abstract
A harvester includes a chassis having a head and an outlet from the head to the chassis. A conveying system moves harvested crop from the gathering assembly to the outlet, the conveying system. The conveying system includes an auger having a rotational axis extending along a longitudinal direction and including a center shaft and a helical blade. An auger pan extends parallel to the rotational axis of the auger. The pan includes a first edge, a planar portion extending beneath the auger, and a trough portion defining a lower section with a generally upward extending surface. An air nozzle extends along the first edge of the pan, the nozzle sloping upward from a first nozzle edge lower than the first edge of the pan to a second nozzle edge higher than the first edge of the pan.

A harvester head, comprising:
- a gathering assembly;
- an outlet;
- a conveying system conveying harvested crop from the gathering assembly to the outlet, the conveying system comprising:
- an auger having a rotational axis extending along a longitudinal direction and including a center shaft and a helical blade;
- a pan extending parallel to the rotational axis of the auger, the pan comprising:
- a first edge at a first side of the rotational axis,
- a first portion extending from the first edge to beneath the auger,
- a trough portion extending from the first portion to a second side of the rotational axis, the trough portion defining a lower section with a generally upward extending surface at the second side of the rotational axis, and
- an auger discharge on the second side of the longitudinal axis;
- a first nozzle extending along the first edge of the pan, the nozzle directing air flow to the trough portion at a bottom of the pan;
- wherein the first nozzle comprises vanes defining a plurality of openings spaced longitudinally along the pan, wherein each of the plurality of openings is substantially directed toward the auger discharge, and wherein the vanes slant progressively more from an orientation substantially perpendicular to the longitudinal direction at a center of the first nozzle to an inward angled orientation at an end of the first nozzle.
