Summary:The mechanism prepares the mixture of straw, chaff and grain arriving in a combine harvester, having a device transporting it over sieves, and a cleaning fan. Between the device (4) and the sieves (5) are an impeller for the mixture, and a rotary drum (8) with holes, inside which is a fan (9) extracting the lightweight ingredients from the mixture. There can be a chamber forming an airtight joint against the outside of the drum, collecting these ingredients and discharging them to the outside, typically by means of an internal auger. L'INVENTION CONCERNE LE MATERIEL DE RECOLTE DES CEREALES.DANS LE DISPOSITIF, UN PROJETEUR 7 DE MELANGE GRAIN-IMPURETES ET UN TAMBOUR PERFORE TOURNANT 8 SONT DISPOSES ENTRE UN ELEMENT TRANSPORTEUR 4 ET DES GRILLES D'EPURATION 5. LE TAMBOUR 8 RENFERME UN VENTILATEUR 9 SERVANT A CAPTER LES IMPURETES LEGERES DU MELANGE GRAIN-IMPURETES TRAITE.L'INVENTION PEUT ETRE UTILISEE DE LA MANIERE LA PLUS EFFICACE POUR LA DIMINUTION DES PERTES EN GRAINS AU COURS DE LA RECOLTE, AINSI QUE POUR LA RECUPERATION DES BALLES PRESENTANT LA PLUS GRANDE VALEUR ALIMENTAIRE.
