The rollers have vertical blades (3) divided along their perimeter which slice through the vegetation during roller rotation. The chassis is connected to a tractor by a pivoting coupling (4) connected by clevises (5) and pins (6) to the chassis front (7) and the rear (8) cross members of the coupling. On the chassis rear cross member (9), clevises (10) and pins (11) are held parallel to a rotating cross member (12). Arms (14) are pivoted, by clevises (15) and pins (16),on the cross member, in the pulling direction. On the end of the arms, pivots (17) retain rotating discs (18). The discs cut and slice in the longitudinal direction of advance the clods of earth and vegetation previously sliced by the blades.

Description

La présente invention concerne un débroussailleur forestier permettant la destruction et le hachage de la végétation arbustive, herbacée, des résidus de coupe, etc
On connaît les débroussailleurs forestiers constitués par un ou deux rouleaux rotatifs maintenus sous un chassis relié à un engin de traction tel que tracteur agricole ou forestier, le ou les rouleaux sont disposés de manière transversale à l'avancement de l'engin de traction et sont dotés de pales linéaires réparties sur leur pourtour de sorte que lors de la rotation du ou desdits rouleaux lesdites pales pénètrent dans le sol en tranchant la végétation ou résidus de coupe tout en aérant ledit sol lors de la rotation des pales.Selon différentes réalisations et la largeur des débroussailleurs, ces derniers sont constitués par au moins deux rouleaux alignés ou selon un léger angle de manière à parfaire l'éclatement de la motte de terre soulevée par les pales lors de la rotation desdits rouleaux. Selon une variante destinée à parfaire le débroussaillage, on connait le couplage des rouleaux sous un chassis, à savoir un premier jeu de rouleaux alignés et un second jeu parallèle de rouleaux inclinés entre eux ou vice versa.
The present invention relates to a forest brush cutter allowing the destruction and chopping of shrub, herbaceous vegetation, cutting residues, etc.
We know the forest brush cutters consisting of one or two rotary rollers held under a chassis connected to a traction unit such as agricultural or forestry tractor, the roller or rollers are arranged transversely to the advance of the traction unit and are provided with linear blades distributed over their periphery so that during the rotation of said roller (s) said blades penetrate into the ground by cutting the vegetation or cutting residues while aerating said soil during the rotation of the blades. width of the brushcutters, the latter consist of at least two rollers aligned or at a slight angle so as to perfect the bursting of the clod of earth raised by the blades during the rotation of said rollers. According to a variant intended to perfect brush cutting, the coupling of the rollers under a chassis is known, namely a first set of aligned rollers and a second parallel set of rollers inclined between them or vice versa.

Dans tous les cas, le débroussailleur est déplacé sur l'ensemble du terrain à nettoyer par passages parallèles successifs longitudinaux et afin de réaliser un débroussaillage complet et de qualité, il est nécessaire de réaliser des passages transversaux parallèles sur toute la surface de la terre de manière à effectuer l'émiettage des mottes de terre et afiner le hachage tant de la végétation que des résidus de coupe.In all cases, the brushcutter is moved over the entire area to be cleaned by successive longitudinal parallel passages and in order to achieve complete and quality brushcutting, it is necessary to make parallel transverse passages over the entire surface of the earth. so as to crumble the clods of earth and to chop both vegetation and cut residues.

Ces types de débroussailleurs nécessitent un temps de travail relativement long puisqu'il est nécessaire de croiser les passages longitudinaux et transversaux.These types of brush cutters require a relatively long working time since it is necessary to cross the longitudinal and transverse passages.

L'invention a pour but de pallier à l'inconvénient précédemment exposé en remplaçant les passages croisés par seulement des passages parallèles longitudinaux.The invention aims to overcome the drawback previously explained by replacing the crossed passages with only longitudinal parallel passages.

Le débroussailleur objet de l'invention est caractérisé en ce qu'il comporte un chassis support de rouleaux alignés ou inclinés entre eux et dont la traverse arrière est dotée de chapes permettant l'articulation d'une traverse parallèle sur laquelle est maintenue articulée une série de bras dans le sens du déplacement, chacun des bras est pourvu en son extrémité d'un pivot orientable en l'extrémité basse duquel est maintenu de manière rotative un disque plat ou concave de telle sorte que lors du déplacement du débroussailleur les lames solidaires des rouleaux tranchent le sol et la végétation selon un axe transversal tandis que les disques tranchent et émiettent selon un axe longitudinal au déplacement. The brushcutter object of the invention is characterized in that it comprises a support frame for rollers aligned or inclined therebetween and the rear crossmember of which is provided with yokes allowing the articulation of a parallel crossmember on which a series of articulated joints is maintained of arms in the direction of movement, each of the arms is provided at its end with an orientable pivot at the lower end of which a flat or concave disc is rotatably held so that during the movement of the brushcutter the blades integral with the rollers cut the soil and vegetation along a transverse axis while the discs cut and crumble along a longitudinal axis when moving.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard des dessins joints donnés à titre d'exemple non limitatif, où - la figure 1 est une vue de côté du débroussailleur en position de travail, - la figure 2, une vue de dessus, - la figure 3, une vue en coupe, les bras arrières et l'attelage relevés pour son transport. Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with reference to the accompanying drawings given by way of nonlimiting example, where - Figure 1 is a side view of the brush cutter in the working position , - Figure 2, a top view, - Figure 3, a sectional view, the rear arms and the hitch raised for transport.
