Abstract:
1. A cob conveying and cleaning system for a harvester operable for discharging a flow of cobs and other residue lighter than the cobs mixed with an air flow, comprising: a conveyor disposed beneath a discharge outlet of the harvester, to convey the flow of cobs and other residue lighter than the cobs from the harvester; residue separating apparatus including a housing disposed above the conveyor, the housing including at least one inlet opening disposed for receiving at least a portion of the air flow and facing the flow of cobs and other residue lighter than the cobs, the housing including an internal cavity containing at least one impeller rotatable in cooperation with the air flow from the harvester for inducting at least a substantial portion of the other residue lighter than the cobs into the housing through the at least one inlet opening and discharging the inducted residue from the housing through the at least one discharge opening, while leaving the cobs to be conveyed from the harvester; wherein the discharge outlet faces downwardly and rearwardly such that the air flow will be directed downwardly and rearwardly therethrough from the harvester, the conveyor is disposed below and rearwardly of the discharge outlet, and the residue separating apparatus is disposed just rearwardly of the discharge outlet such that the inlet opening is positioned in a path of the air flow, and wherein the at least one impeller is configured to generate sufficient induction when rotated, to induct the air flow in a manner so as to carry the residue lighter than the cobs away from the cobs and into the housing, and a deflector that deflects a flow of rearward air propelled from a threshing system of the harvester, the deflector deflects the flow downwardly to mix with a further flow from fan of the cleaning system for a break-up thereof, such that the further flow must pass through the flow before entering the at least one inlet system of the housing.
