Abstract
A combine harvester includes a cleaning shoe, which has a chaffer, a sieve below the chaffer, a blower configured to direct air rearward and upward through the sieve and the chaffer, and an air channel assembly defining a plurality of longitudinal air channels positioned to receive air from the blower under a forward end of the sieve and deliver the air to a position rearward along a length of the sieve. The air channels are spaced such that the air channel assembly defines free paths between adjacent air channels such that grain falling downward through the sieve does not obstruct rearward air flow through the air channels.
