Abstract
Un procédé d'accrochage de fléaux pour appareils de broyage ou de fauche d'herbe consiste à munir chaque fléau (10) d'un crochet (11) dont la partie centrale (12) a pratiquement la même forme que la partie inférieure travaillante (16) de la manille (14) et dont l'ouverture comporte un rétrécissement (13), de sorte que le fléau (10) ne puisse pas se décrocher, et à munir ladite manille (14), au moins sur un de ses côtés non travaillant, d'une partie amincie (15) permettant d'insérer le crochet (11) du fléau (10) dans la manille (14).A method of attaching flails for mulching or mowing grass devices consists in providing each flail (10) with a hook (11), the central part (12) of which has practically the same shape as the working lower part ( 16) of the shackle (14) and the opening of which has a narrowing (13), so that the beam (10) cannot come loose, and to provide said shackle (14), at least on one of its sides non-working, with a thinned part (15) allowing the hook (11) of the flail (10) to be inserted into the shackle (14).
Description
La présente invention a pour objet un procédé d'accrochage de fléaux pour appareils de broyage ou de fauche tels que des épareuses broyeuses de sarments de paille ou de tiges de maïs, ainsi que les moyens pour la mise en oeuvre de ce proce Dans les appareils connus, les fléaux comportent un oeillet qui est enfilé une manille ; de sorte que lorsque les fléaux doivent être remplacés, il faut démonter chaque manille portant un fléau ce qui prend beaucoup de temps. The subject of the present invention is a method for attaching plagues for grinding or mowing apparatuses such as mulchers of straw branches or corn stalks, as well as the means for implementing this process. In the apparatuses known, the plagues comprise an eyelet which is threaded a shackle; so that when the flails have to be replaced, it is necessary to disassemble each shackle carrying a flail which takes a long time.
Le procédé selon l'invention consiste à munir chaque fléau d'un crochet dont partie centrale a pratiquement le même diamètre que la partie inférieure travaillante de la manille ; et dont l'ouverture a une dimension inférieure de sorte 'il ne puisse pas s'en échapper et à munir au moins un des côtés, non travaillant, de la manille d'une partie amincie permettant d'insérer le crochet dans la manille. The method according to the invention consists in providing each flail with a hook, the central part of which has practically the same diameter as the lower working part of the shackle; and the opening of which has a smaller dimension so that it cannot escape from it and to provide at least one of the non-working sides of the shackle with a thinned part allowing the hook to be inserted into the shackle.
A titre d'exemples non limitatifs et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés - Figures 1 et 2, deux vues en perspective illustrant les dispositions antérieures connues. By way of nonlimiting examples and to facilitate understanding of the invention, there is shown in the accompanying drawings - Figures 1 and 2, two perspective views illustrating the known prior arrangements.
- Figure 3, une vue illustrant un exemple de réalisation du fléau à crochet et de la manille. - Figure 3, a view illustrating an exemplary embodiment of the hook flail and the shackle.
- Figures 4a à 4c, trois vues illustrant la mise en place du fléau à crochet de la figure 3. - Figures 4a to 4c, three views illustrating the positioning of the hook flail of Figure 3.
- Figure 5, une vue illustrant quatre exemples de réalisation du fléau à crochet pouvant être mis en place dans la manille. - Figure 5, a view illustrating four exemplary embodiments of the hook beam which can be placed in the shackle.
En se reportant aux figures 1 et 2, on voit que les appareils de broyage ou de fauche de type connu comportent un arbre 1, entraîné en rotation à grande vitesse, au moyen d'oreilles 4 portent des manilles telles que 2 ou 3 dans lesquelles sont enfilés les aeilletons 7 de fléaux tels que 5 ou 6. Referring to Figures 1 and 2, it can be seen that the grinding or mowing apparatus of known type comprises a shaft 1, driven in rotation at high speed, by means of ears 4 carry shackles such as 2 or 3 in which are threaded the eyelets 7 of plagues such as 5 or 6.
On comprend que pour changer les fléaux tels que 5 ou 6, il faut démonter chaque manille 2 ou 3 en dévissant l'ensemble boulon-écrou 8. We understand that to change the flails such as 5 or 6, each shackle 2 or 3 must be removed by unscrewing the bolt-nut assembly 8.
Lorsqu'il faut changer tous les fléaux 5 ou 6 portés par un arbre 1, cette operation peut être très longue. La présente invention a pour but de supprimer cet inconvénient en rendant très facile et très rapide le remplacement des fléaux. When it is necessary to change all the flails 5 or 6 carried by a shaft 1, this operation can be very long. The present invention aims to eliminate this drawback by making it very easy and very quick to replace the plagues.
Sur la figure 3, on voit que le fléau 10 ne comporte plus un oeilleton, tel que l'oeilleton des figures 1 et 2, enfilé dans la manille, mais un crochet 11. In FIG. 3, it can be seen that the beam 10 no longer comprises an eyelet, such as the eyelet of FIGS. 1 and 2, threaded into the shackle, but a hook 11.
crochet 11 comporte une partie centrale 12, de section circulaire, dont la forme correspond exactement à celle de la partie travaillante 16 de la manille 14 et un rétrecissement 13 qui a pour effet que le fléau 10 ne puisse pas se décrocher de la manille permettre d'enfiler le crochet 11 sur la manille 14, celle-ci comporte, sur au moins un de ses côtés, une partie amincie 15 de sorte qu'à cet endroit l'épaisseur de la manille 14 soit légèrement inférieure à la dimension de l'ouverture du crochet au niveau rétrécissement 13. hook 11 comprises a central part 12, of circular section, the shape of which corresponds exactly to that of the working part 16 of the shackle 14 and a narrowing 13 which has the effect that the beam 10 cannot be detached from the shackle allowing d thread the hook 11 on the shackle 14, the latter comprises, on at least one of its sides, a thinned part 15 so that at this point the thickness of the shackle 14 is slightly less than the dimension of the opening of the hook at the narrowing level 13.
figures 4a à 4c illustrent comment le crochet 11 est enfilé dans manille 14 en passant par la partie amincie 15 de celle-ci. Figures 4a to 4c illustrate how the hook 11 is threaded into the shackle 14 passing through the thinned part 15 thereof.
Sur la figure 5, on voit que sur une même manille 14 on peut disposer plusieurs types de fléaux 10, quatre dans l'exemple représenté. In Figure 5, we see that on the same shackle 14 can have several types of flails 10, four in the example shown.
Le fléau 10a est un fléau de forme classique correspondant à la figure 1. The beam 10a is a beam of conventional shape corresponding to FIG. 1.
Les fléaux 10b, 10c et 10d correspondent au fléau de coupe de la figure 2 : le fléau 10b avec un crochet 11 tourné vers l'avant, le fléau 10c avec un crochet 11 tourné vers l'arrière ; le fléau 10d étant un fléau double réversible. The beams 10b, 10c and 10d correspond to the cutting beam of Figure 2: the beam 10b with a hook 11 facing forward, the beam 10c with a hook 11 facing backward; the flail 10d being a double reversible flail.
Ces trois fléaux 10b, 10c et 10d ont une forme particulière : leur crochet 11 est placé à une extrémité d'une tige 20 qui porte à son autre extrémité pièce de coupe 21 ayant une forme sensiblement rectangulaire ; la pièce de coupe 21 des fléaux 10b et 10c étant légèrement incurvée à la façon d'une cuillère, pièce de coupe 21 fléau 10d étant double de façon à pouvoir être réversible. These three plagues 10b, 10c and 10d have a particular shape: their hook 11 is placed at one end of a rod 20 which carries at its other end cutting part 21 having a substantially rectangular shape; the cutting piece 21 of the flails 10b and 10c being slightly curved like a spoon, cutting piece 21 flail 10d being double so as to be able to be reversible.
partie avant de la pièce 21, qui affecte la coupe peut être biseautée soit en un simple biseau ou en double biseau. front part of the part 21, which affects the cut can be bevelled either with a single bevel or with a double bevel.
De plus, dans le cas des fléaux 10a et l0d, la position du fléau peut être inversée selon que l'on tourne le crochet 11 vers l'avant ou vers l'arrière. Il faut alors équilibrer le fléau de telle façon que son centre de gravité passe par plan médian du crochet 1 Dans cas du fléau 10d, lorsque le fléau est inversé, le côté opposé au côté qui effectue la coupe est soumis à un effet d'auto-affûtage. In addition, in the case of flails 10a and 10d, the position of the flail can be reversed depending on whether the hook 11 is rotated forward or backward. It is then necessary to balance the beam so that its center of gravity passes through the median plane of the hook 1 In the case of beam 10d, when the beam is reversed, the side opposite to the side which performs the cut is subjected to an auto effect -sharpening.
Selon une variante de réalisation on peut réaliser l'amincissement 15 par forgeage en refoulant la matière vers l'intérieur de la manille, ce provoque l'apparition d'un bourrelet qui renforce le maintien en place du fléau. According to an alternative embodiment, thinning can be carried out by forging by pushing the material towards the inside of the shackle, which causes the appearance of a bead which reinforces the holding in place of the beam.
Bien entendu la présente invention couvre non seulement le procédé consistant à remplacer foeilleton 7 par un crochet 11 ; mais également les produits au moyen desquels ledit procédé est mis en oeuvre c'est-à-dire un fléau à crochet 11 muni d'une ouverture 13 rétrécie et la manille 14 munie d'un amincissement 15 permettant de faire pénétrer le crochet 11 dans la manille 14. Of course, the present invention covers not only the method consisting in replacing the eyelet 7 by a hook 11; but also the products by means of which said method is implemented, that is to say a hook flail 11 provided with a narrowed opening 13 and the shackle 14 provided with a thinning 15 allowing the hook 11 to penetrate into shackle 14.
En travail, le crochet 12 repose sur la partie travaillante 16 de la manille 14 ; alors que l'amincissement 15 est pratiqué sur au moins un des côtés non travaillant de la manille.In work, the hook 12 rests on the working part 16 of the shackle 14; while the thinning 15 is carried out on at least one of the non-working sides of the shackle.
