Description

Perfectionnement aux machines à couper, faucher et broyer les végétaux.Improvement in machines for cutting, mowing and grinding plants.

La présente invention se rapporte aux machines à couper, faucher et broyer les végétaux comportant un rotor tournant à grande vitesse, muni de fléaux constituant-les outils de coupe. The present invention relates to machines for cutting, mowing and grinding plants comprising a rotor rotating at high speed, provided with flails constituting the cutting tools.

De nombreuses machines actuellement connues, sont équi pées d'un groupe de coupe du genre de celui représenté figure 1. Le rotor 1, avec ses couteaux 2, est monté dans un carter 5 par l'intermédiaire de deux paliers 3 et 4. Le rotor 1 est entrainé en rotation au moyen d'un moteur 9, de pignons 6 et 8 et d'une chaîne 7, par exemple, mais non exclusivement.Le rotor 1 comporte de nombreux fléaux démontables 2 qui frappent, coupent et broient la végétation rencontrée et, par conséquent, qui s'usent. Many machines currently known, are equipped with a cutting group of the kind shown in FIG. 1. The rotor 1, with its knives 2, is mounted in a casing 5 by means of two bearings 3 and 4. The rotor 1 is driven in rotation by means of a motor 9, sprockets 6 and 8 and a chain 7, for example, but not exclusively. The rotor 1 has many removable flails 2 which strike, cut and grind the vegetation encountered and, therefore, which wear out.

Les différents types de végétation à traiter, ont conduit les constructeurs à proposer plusieurs modèles de couteaux, voire plusieurs modèles de rotors. Mais on constate que l'échange complet des fléaux, ou leur retournement est une opération longue et fastidieuse. D'autre part, le remplacement d'un rotor 1 par un autre est d'autant plus long qu'il nécessite le démontage des deux paliers 3 et 4 et du pignon 6. The different types of vegetation to be treated have led manufacturers to offer several models of knives, or even several models of rotors. But we see that the complete exchange of plagues, or their reversal is a long and tedious operation. On the other hand, the replacement of one rotor 1 by another is all the longer as it requires the disassembly of the two bearings 3 and 4 and of the pinion 6.

Un premier perfectionnement déjà proposé a consisté, comme l'illustre la figure 2 du dessin, à fixer le rotor 1, d'un cdté à un arbre 10 par des vis Il et de l'autre cOté à le faire reposer sur un palier 12 rendu solidaire du carter 5 au moyen de boulons 13, ledit palier 12 faisant corps avec le rotor. Dans cette solution, le remplacement du rotor 1 par un autre est rapide, grâce au démontage des vis ll et des boulons 13, mais l'échange complet des fléaux 2, ou leur retournement est aussi long et fastidieux que dans le cas précédent montré schématiquement figure 1. A first improvement already proposed consisted, as illustrated in FIG. 2 of the drawing, in fixing the rotor 1, on one side to a shaft 10 by screws II and on the other side to resting it on a bearing 12 secured to the casing 5 by means of bolts 13, said bearing 12 being integral with the rotor. In this solution, the replacement of the rotor 1 by another is fast, thanks to the disassembly of the screws ll and the bolts 13, but the complete exchange of the flails 2, or their reversal is as long and tedious as in the previous case shown schematically figure 1.

Le perfectionnement objet de la présente invention a pour but de remédier à cet inconvénient. I1 permet en effet d'effectuer le retournement, ou le changement rapide du rotor porte-fléaux ; de réaliser un rotor plus léger et moins coOteux; de supprimer les parties délicates du rotor; de concevoir différemment les paliers supportant l'arbre de faciliter le démontage des parties solidaires du carter. The object of the improvement of the present invention is to remedy this drawback. I1 makes it possible to effect the reversal, or the rapid change of the flail-carrying rotor; to make a lighter and less expensive rotor; to remove the delicate parts of the rotor; to design the bearings supporting the shaft differently to facilitate disassembly of the integral parts of the housing.

Selon l'invention, la caractéistique essentielle du montage réside dans le fait que le rotor est rendu solidaire des arbres porteurs et de leurs paliers, au moyen de deux brides d'extrémités à emboîtement mâle et femelle, dont une partie appartient au rotor, tandis que l'autre prolonge l'arbre porteur et/ou moteur, dont le palier demeure fixé au carter. According to the invention, the essential characteristic of the assembly resides in the fact that the rotor is made integral with the bearing shafts and their bearings, by means of two end flanges with male and female interlocking, part of which belongs to the rotor, while the other extends the carrier and / or motor shaft, the bearing of which remains fixed to the casing.

L'invention est exposée ci-après plus en détail à l'aide de dessins schématiques en représentant seulement un mode d'exécution. The invention is set out below in more detail using schematic drawings showing only one embodiment.

La figure 3 représente le montage d'un groupe de coupe selon l'invention. Figure 3 shows the assembly of a cutting group according to the invention.

La figure 4 montre le rotor de profil avec l'indication du sens de rotation et des parties d'usure des fléaux. Figure 4 shows the profile rotor with the indication of the direction of rotation and the wear parts of the flails.

La figure 5 est une vue identique à la précédente figure 3, après retournement du rotor. Figure 5 is a view identical to the previous Figure 3, after inversion of the rotor.

La figure 6 est une vue de profil du rot or de la figure 5, montrant qu'après retournement les arêtes non -usées des fléaux sont en mesure d'être utilisées. Figure 6 is a side view of the gold rot of Figure 5, showing that after turning the non-worn edges of the flails are able to be used.

Le rotor 1 comporte à une extrémité l'emboitement mâle 17 d'une bride 18. D'un c9té la bride 18 est solidaire de l'arbre moteur 19 porté par un palier 20 fixé au carter 5. The rotor 1 has at one end the male socket 17 of a flange 18. On one side the flange 18 is integral with the motor shaft 19 carried by a bearing 20 fixed to the casing 5.

L'assemblage des parties 17 et 18 de la bride est assuré au moyen de boulons ou de vis 21.The assembly of parts 17 and 18 of the flange is ensured by means of bolts or screws 21.

Le rotor 1 comporte à l'autre extrémité l'emboitement mâle 22 d'une bride 23 solidaire d'un arbre porteur 24 porté par un palier 25 monté réglable sur le carter 5 au moyen de boulons ou de vis 26. L'assemblage des parties 22 et 23 de la bride est assuré par des boulons ou des vis 27. The rotor 1 comprises at the other end the male socket 22 of a flange 23 secured to a carrier shaft 24 carried by a bearing 25 mounted adjustable on the casing 5 by means of bolts or screws 26. The assembly of the parts 22 and 23 of the flange are secured by bolts or screws 27.

A la manière connue, le rotor 1 comporte des étriers de fixation de plusieurs paires de fléaux 2 qui sont entraînés dans le sens de rotation du rotor indiqué par la flèche S. In the known manner, the rotor 1 comprises brackets for fixing several pairs of flails 2 which are driven in the direction of rotation of the rotor indicated by the arrow S.

Dans ces conditions, c'est l'arête C des fléaux 2 qui s'use, alors que l'arête D est en bon état.Under these conditions, it is the edge C of the flails 2 which wears out, while the edge D is in good condition.

En retournant le rotor 1, après glissement latéral du palier 25 et désolidarisation des parties 17 et 22 des brides 18 et 23 et après dévissage des boulons 21 et 26, on constate que c'est l'arête D des fléaux non usée qui va assurer la coupe, le sens de rotation S du rotor demeurant le même qu'auparavant. Returning the rotor 1, after lateral sliding of the bearing 25 and separation of the parts 17 and 22 of the flanges 18 and 23 and after unscrewing the bolts 21 and 26, it is found that it is the edge D of the unworn flails which will ensure cutting, the direction of rotation S of the rotor remaining the same as before.

On peut de la même manière changer aisément et rapidement de rotor 1, notamment en cas de détérioration, ou pour utiliser d'autres formes des fléaux 2 pour une végétation différente. We can in the same way easily and quickly change the rotor 1, in particular in the event of deterioration, or to use other forms of the plagues 2 for a different vegetation.

Il est du-reste bien entendu que le mode de réalisation qui a été décrit ci-dessus a été donné à titre purement indicatif et nullement limitatif et que de nombreuses modifications peuvent être apportées sans qu'on s'écarte pour cela du cadre de la présente invention.  It is, moreover, of course understood that the embodiment which has been described above has been given for purely indicative and in no way limiting and that numerous modifications can be made without departing from the scope of the present invention.
