Abstract

La présente invention concerne un couvre-rouleaux avec plaques de guidage de l'herbe à angles réglables qui comprend un corps (1) de couvre-rouleaux et une plaque de raccordement (4). Plusieurs plaques de guidage de l'herbe (2) mobiles sont articulées sur la paroi interne du corps (1) de couvre-rouleaux, et un trou oblong (3) est formé à une extrémité de chaque plaque de guidage de l'herbe (2) mobile. La plaque de raccordement (4) décrit un mouvement limité dans un rail de coulissement sur le côté interne du corps (1) de couvre-rouleaux, et le rail de coulissement s'étend longitudinalement le long du corps (1) de couvre-rouleaux. De premiers arbres de fourche (5) sont agencés de manière fixe sur la plaque de raccordement (4), le nombre de premiers arbres de fourche (5) correspondant à celui des plaques de guidage de l'herbe (2) mobiles, et les premiers arbres de fourche (5) décrivent un mouvement limité dans les trous oblongs (3) des plaques de guidage de l'herbe (2) mobiles. Un mécanisme de commande permettant d'actionner la plaque de raccordement (4) pour qu'elle coulisse le long du rail de coulissement est monté sur le corps (1) de couvre-rouleaux. Le couvre-rouleaux avec les plaques de guidage de l'herbe à angles réglables est pratique à manipuler et les angles de montage des plaques de guidage de l'herbe (2) réglables peuvent être modifiés par une légère force de commande afin de pouvoir réguler le temps de battage des cultures dans une chambre de battage, de manière à améliorer les performances de battage des cultures et à réduire les pertes lors du battage.
