Abstract

A twine-cutting assembly for a machine which cops up bales of hay, etc. for distribution. The machine is of the type which has a casing contg. a rotor having radial arms equipped for chopping materials e.g. like a hammer mill. Baling twince can impede the chopping action if it becomes wound around the rotor shaft. On both sides of the rotor and spaced from the axis of rotation are fixed one or more axially-projecting shear blades. As these rotate they provide a cyclic shearing action with corresp. blades fixed to the inside of the casing.

Description

La distribution des balles rondes, cylindriques ou rectangulaires de paille ou fourrage pose le problème d'enlever les ficelles avant l'opération de distribution par un rotor a marteaux. The distribution of round, cylindrical or rectangular bales of straw or fodder poses the problem of removing the strings before the distribution operation by a hammer rotor.

La ficelle, en s'enroulant autour de l'axe du rotor, peut causer des détériorations aux roulements de l'axe.The twine, by wrapping around the rotor axis, can cause damage to the axis bearings.

L'objet de cette invention est de déchiqueter la ficelle au fur et a mesure qu'elle essaie de s'enrouler autour du rotor. The object of this invention is to shred the string as it tries to wrap around the rotor.

A cet effet, au moins un jeu de couteaux est fixé sur le rotor, les deux couteaux de chaque jeu étant placés symétriquement par rapport à l'axe du rotor et uniformément répartis sur un cercle. To this end, at least one set of knives is fixed to the rotor, the two knives of each set being placed symmetrically with respect to the axis of the rotor and uniformly distributed over a circle.

Au moins un second jeu de couteau est fixé sur les parois du carter qui enveloppent le rotor, de la même manière symétrique, suivant un même cercle tangentant celui correspondant aux couteaux du rotor ou suivant des cercles de rayons différents alternativement inférieur et supérieur au rayon correspondant au cercle comprenant les couteaux du rotor. At least a second set of knives is fixed to the walls of the casing which surround the rotor, in the same symmetrical manner, in the same tangent circle as that corresponding to the blades of the rotor or in circles of different radii alternately smaller and larger than the corresponding radius to the circle comprising the blades of the rotor.

Les deux jeux de couteaux sont placés en opposition de sorte que, lorsqu'une ficelle se présente, elle n'a pas d'autre issue possible que d'être entraînée par les couteaux du rotor et tranchée contre les couteaux fixes. Les morceaux de ficelle sont alors entraînés par la paille ou le fourrage distribué, et éjectés au travers de la goulotte. The two sets of knives are placed in opposition so that, when a string presents itself, it has no other possible outcome than to be driven by the blades of the rotor and cut against the fixed knives. The pieces of string are then entrained by the straw or the fodder distributed, and ejected through the chute.

On décrira plus en détail ci-après un coupe-ficelle suivant l'invention, à titre d'exemple indicatif et nullement limitatif, en référence au dessin annexé sur lequel
La figure 1 est une vue en coupe suivant I-I de la figure 2.
A twine cutter according to the invention will be described in more detail below, by way of an indicative and in no way limitative example, with reference to the appended drawing in which
FIG. 1 is a sectional view along II of FIG. 2.

La figure 2 est une vue en plan par dessus suivant la flèche F de la figure 1.  FIG. 2 is a plan view from above along the arrow F in FIG. 1.

Sur le rotor 1 représenté schéniatiquement est fixé symétri- quement par rapport à son axe et vers sa périphérie au moins un jeu de deux couteaux 2, tandis que sur le carter 3 du hacheur 4 est fixé également symétriquement au moins un jeu de deux couteaux décalés diamétralement, c'est-a-dire que l'un 5 est fixé suivant un cercle extérieur à celui contenant les couteaux 2 et l'autre 6 sur un cercle intérieur, de sorte que les couteaux 5 et 6 cisaillent la ficelle par leur passage en decca et au-delà des couteaux fixes 2, dans le sens de rotation indiqué par les flèches. On the rotor 1 shown schematically is fixed symmetrically with respect to its axis and towards its periphery at least one set of two knives 2, while on the casing 3 of the chopper 4 is also symmetrically fixed at least one set of two offset knives diametrically, that is to say that one 5 is fixed in a circle external to that containing the knives 2 and the other 6 on an internal circle, so that the knives 5 and 6 shear the string by their passage in decca and beyond the fixed knives 2, in the direction of rotation indicated by the arrows.

Les couteaux 5 et 6 pourraient aussi être fixés sur le carter du hacheur sur un même cercle tangeant a celui correspondant aux couteaux 2. The knives 5 and 6 could also be fixed to the chopper housing on the same circle tangent to that corresponding to the knives 2.

Le nombre et la disposition de ces couteaux peut naturellement varier, leur co-action assurant de façon certaine le déchiquetage des ficelles des balles qui sont ensuite distribuées au travers de la goulotte a l'état finement dispersées.  The number and arrangement of these knives can naturally vary, their co-action certainly ensuring the shredding of the strings of the bales which are then distributed through the chute in the finely dispersed state.
