Abstract

The device has a shredding head (1) arranged at an end of a steerable arm carried by a tractor machine to move along the plants to be treated. The head has housing (10) with two parallel end plates (11, 12) between which are mounted two juxtaposed rotors (13, 14) with parallel axes. The rotors have radial blades (15) driven in rotation in opposite directions (F, R), such that the blades move in a space (16) which separates the rotors and drive inside the plants to be cut and shredded.

Description

La présente invention a pour objet un dispositif d'élagage et de broyageThe present invention relates to a device for pruning and grinding

de la végétation.vegetation.

Le dispositif d'élagage et de broyage de la végétation selon l'invention comporte une tête de broyage disposée à l'extrémité d'un bras orientable lui-même porté par un engin tracteur apte à se déplacer le long de la végétation à traiter, ladite tête comporte un carter comprenant deux flasques parallèles entre lesquels sont montés deux rotors juxtaposés d'axes parallèles, équipés de couteaux radiaux et aptes à être entraînés en rotation dans des sens inverses, en sorte que les couteaux desdits rotors évoluent dans l'espace qui sépare lesdits rotors et y entraînent la végétation en vue de la couper et de la broyer.  The device for pruning and grinding the vegetation according to the invention comprises a grinding head disposed at the end of a steerable arm itself carried by a tractor capable of moving along the vegetation to be treated, said head comprises a housing comprising two parallel flanges between which are mounted two rotors juxtaposed parallel axes, equipped with radial knives and adapted to be rotated in opposite directions, so that the knives of said rotors move in the space which separates said rotors and drives vegetation therein for the purpose of cutting and grinding it.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.  The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé : - la figure 1 représente une vue schématique de côté d'une 20 partie du dispositif d'élagage et de broyage de la végétation selon l'invention.  In the accompanying drawing: - Figure 1 shows a schematic side view of a portion of the device for pruning and grinding the vegetation according to the invention.

- la figure 2 représente une vue schématique sous un autre angle du même dispositif.  - Figure 2 shows a schematic view from another angle of the same device.

En référence à ces figures on peut voir qu'un dispositif d'élagage et de broyage de la végétation selon l'invention comprend une tête 1 montée à l'extrémité d'un bras articulé 2, visible sur la figure 2.  With reference to these figures it can be seen that a device for pruning and grinding the vegetation according to the invention comprises a head 1 mounted at the end of an articulated arm 2, visible in FIG.

La tête 1 comporte un carter 10 comprenant deux flasques 11 et 12 qui enserrent et maintiennent deux rotors 13 et 14 d'axes parallèles qui se présentent chacun sous la forme d'un corps cylindre muni de couteaux radiaux 15, et séparés par un espace 16 dans lequel évoluent les couteaux 15.  The head 1 comprises a housing 10 comprising two flanges 11 and 12 which enclose and hold two rotors 13 and 14 of parallel axes which are each in the form of a cylinder body provided with radial knives 15, and separated by a space 16 in which the knives evolve 15.

Les deux rotors 13 et 14 sont entraînés en contre rotation, dans le sens des flèches respectivement F et R, en sorte d'entraîner la végétation dans l'espace 16, et de réaliser, dans le carter 10, son broyage.  The two rotors 13 and 14 are driven in counter-rotation, in the direction of arrows respectively F and R, so as to cause vegetation in the space 16, and to achieve, in the housing 10, its grinding.

La tête 1 comporte également des éléments racleurs 17 solidaires du carter 1 et s'étendant entre les couteaux 15 pour venir pratiquement au contact des corps des rotors 13 et 14.  The head 1 also comprises scraper elements 17 integral with the housing 1 and extending between the knives 15 to come into substantially contact with the bodies of the rotors 13 and 14.

La tête 1 présente à chacune de ses extrémités, c'est-à- dire de part et d'autre des rotors 13 et 14, une ouverture 18 permettant l'évacuation du broyat.  The head 1 has at each of its ends, that is to say on either side of the rotors 13 and 14, an opening 18 for the discharge of the ground material.

Le bras articulé 2, qui en l'occurrence est solidarisé au flasque 12, permet de déplacer la tête 1 par rapport à la végétation, et notamment en sorte que le flasque 11 demeure sensiblement parallèle au sens de déplacement et la végétation.  The articulated arm 2, which in this case is secured to the flange 12, moves the head 1 relative to the vegetation, and in particular so that the flange 11 remains substantially parallel to the direction of movement and vegetation.

Le bras articulé 2 comprend essentiellement un bras 20 mobile en déplacement pendulaire et solidarisé à la tête 1 en regard du rotor 14, et un vérin 21 dont l'extrémité est solidarisée à la tête 1 en regard du rotor 13, et qui est destiné, au gré de son allongement ou de son raccourcissement, à faire varier l'inclinaison de la tête 1.  The articulated arm 2 essentially comprises a movable arm 20 in pendular displacement and secured to the head 1 opposite the rotor 14, and a jack 21 whose end is secured to the head 1 facing the rotor 13, and which is intended, according to its elongation or its shortening, to vary the inclination of the head 1.

Le bras 20 est doublé d'un arbre d'entraînement 22 qui transmet le mouvement au rotor 14, tandis qu'un arbre de transmission 23 permet l'entraînement du rotor 13.  The arm 20 is doubled by a drive shaft 22 which transmits the movement to the rotor 14, while a transmission shaft 23 allows the rotor 13 to be driven.
