An agricultural combine having an enlarged cleaning area for enhancing the handling capacity of the machine without increasing the outside configuration thereof. The agricultural combine includes an elongated walled body arranged about and along an elongated separating mechanism. The combine further includes a cleaning station having a generally horizonal sieve disposed below the separating station so as to directly receive materials passing therefrom. The cleaning station further includes a blower assembly for directing a pressurized stream of air from an outlet end upwardly through the sieve thereby effecting a further cleaning function of the grain. The clean grain passing through the cleaning station falls into a clean grain area from whence an elevator transports the clean grain an enhanced holding tank defined within the walled body of the combine. An apparatus is disposed proximate to and rearwardly of the outlet of the blower assembly for forcibly propelling material passing through and from the sieve away from the outlet end of the blower assembly. The apparatus is fitted relative to the combine such that the outer configuration of the combine remains substantially unchanged while enhancing the cleaning capacity thereof.

Moissonneuse-batteuse à zone de nettoyage élargie, qui permet d'augmenter la capacité de la machine sans en accroître la configuration externe. La machine comprend un bâti allongé fermé, disposé autour et le long d'un séparateur allongé. Elle comporte en outre un nettoyeur muni d'un tamis essentiellement horizontal placé sous le séparateur afin de recevoir directement le matériau provenant de ce dernier. Le nettoyeur est doté en outre d'une soufflerie qui dirige un jet d'air comprimé, à partir d'une sortie orientée vers le haut, à travers le tamis, qui nettoie le grain davantage. Le grain nettoyé qui passe dans le nettoyeur tombe dans une zone de réception de grain nettoyé où un mécanisme d'élévation le transporte dans un réservoir amélioré situé à l'intérieur du bâti de la machine. Un dispositif placé près et en arrière de la sortie de la soufflerie force le matériau passant à travers le tamis et provenant de ce dernier dans une direction opposée à la sortie de la soufflerie. L'appareil est installé à l'intérieur de la moissonneuse-batteuse, de sorte qu'il n'en change pratiquement pas la configuration externe, tout en accroissant sa capacité de nettoyage.
