Abstract

La présente invention concerne une machine de coupe et de conditionnement de biomasse présentant une fonctionnalité adaptée au procédé de traitement de biomasse proposé pour en améliorer les caractéristiques en vue d'une utilisation comme biocombustible. Cette machine permet de couper les tiges qui se trouvent sur toute la largeur avant, par contact avec les dents (3) qui conduisent la matière ligneuse vers l'ensemble de coupe, lequel est constitué de lames (2) alignées latéralement avec espacement constant. Ledit ensemble de coupe est protégé par un ensemble de dents (3) en nombre égal à celui des lames de coupe. De plus, dans la zone avant, au-dessus dudit ensemble de coupe, se trouve un rouleau avant (12) présentant des dents qui permettent d'appliquer une force visant à tirer la matière ligneuse vers l'intérieur de la structure (1). Ledit ensemble de coupe possède en outre un rouleau de sortie (21) permettant la sortie de la matière avec le conditionnement souhaité.
