Abstract

Selon l'invention, un capot de chambre de battage (18) recouvre au moins une partie supérieure d'un cylindre de batteuse (13) et une partie supérieure d'un dispositif de traitement d'épis coupés (14). Des dents de battage (17) formées sur le cylindre de batteuse (13) sont plates le long d'un plan parallèle à la direction axiale du cylindre de batteuse (13). Le dispositif de traitement d'épis coupés (14) traite les épis coupés produits sur le cylindre de batteuse (13). Le couvercle de la chambre de batteuse (18) est formé de sorte que, dans la coupe transversale prise le long d'un plan perpendiculaire à la direction axiale, la distance à partir de la circonférence externe du cylindre de batteuse (13) augmente progressivement dans la direction vers le bas par rapport à la direction de rotation du cylindre de batteuse (13), un espace étant formé au-dessus du cylindre de batteuse (13) et au-dessus du dispositif de traitement des épis coupés (14). Avec une telle structure, les pédoncules des grains (22) peuvent s'éloigner de la circonférence externe du cylindre de batteuse (13) et, en conséquence, il est possible d'empêcher que lesdits pédoncules (22) s'enroulent autour du cylindre de batteuse (13) et de supprimer toute consommation d'énergie inutile du cylindre de batteuse (13).
