Il est constitué de plusieurs axes polygonaux (2), munis de couteaux(5) montés de manière hélicoïdales(figure 2) et suffisamment espacés pour permettre le croisement des couteaux de l'axe supérieur (6) avec ceux de l'axe inférieur(2), qui, lors de leur rotation décompactent et homogénéisent les fibres ou particules, afin de pouvoir être appliquées par la suite au sol au moyen du système de projection. Le tapis convoyeur (7)pourra être décalé afin de permettre aux fibres ou particules le passage dans le système de projection sans nécessairement passer par les couteaux. Le dispositif selon d'invention est particulièrement destiné à l'application de fibres ou particules au sol pour le marché du paysage et de l'agriculture.The invention relates to a device (8) for decompacting and homogenizing fibers or particles, whether compressed or not, in order to apply them to the ground. It consists of several polygonal axes (2), provided with knives (5) mounted helically (Figure 2) and sufficiently spaced to allow the knives of the upper axis (6) to cross those of the lower axis ( 2), which, during their rotation decompact and homogenize the fibers or particles, so that they can be subsequently applied to the ground by means of the projection system. The conveyor belt (7) can be offset to allow the fibers or particles to pass through the projection system without necessarily passing through the knives. The device according to the invention is particularly intended for the application of fibers or particles to the soil for the landscape and agriculture market.

Description

La présente invention concerne un dispositif pour décompacter et homogénéiser de la fibres ou particules végétales compressées ou non dans le but de l'appliquer sur le sol.The present invention relates to a device for decompacting and homogenizing plant fibers or particles, whether compressed or not, in order to apply it to the ground.

Le décompactage est traditionnellement effectué soit manuellement, soit au moyen de cardes, et lors de leur utilisation, les fibres longues végétales mais pas uniquement, ont tendance à se tisser et s'amalgamer autour de l'axe, ce qui rend le système de cardes inopérant.The decompaction is traditionally carried out either manually or by means of cards, and during their use, the long vegetable fibers but not only, tend to weave and amalgamate around the axis, which makes the card system inoperative.

Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique, une série de couteaux à plusieurs dents, en quantité non limitative, en forme d'étoile mais pas seulement, usinés en leur centre par un orifice de forme polygonale, leur permettant d'être montés sur un axe luimême polygonale de même dimension, afin d'empêcher les couteaux de tourner sur cet axe lors de leur rotation en cas fortes contraintes mécaniques mais aussi de permettre lors de l'assemblage un décalage régulier entre chacun des couteaux dans le but d'obtenir une séquence d'attaque progressive des fibres ou particules de manière hélicoïdale, entraînant celles-ci vers la suite de leurs traitements dans la machine et leur centrifugation pour pousser ces fibres ou particules.The device according to the invention overcomes this drawback. According to a first characteristic, it comprises a series of knives with several teeth, in nonlimiting quantity, in the shape of a star but not only, machined in their center by an orifice of polygonal shape, allowing them to be mounted on a same polygonal axis of the same dimension, in order to prevent the knives from turning on this axis during their rotation in the event of high mechanical stresses but also to allow during assembly a regular offset between each of the knives in order to obtain a sequence of progressive attack of the fibers or particles in a helical manner, driving them towards the continuation of their treatments in the machine and their centrifugation to push these fibers or particles.

Entre chaque couteau, sera laissé un espaces au moins égal à l'épaisseur d'une unité de couteau, permettant à chaque axe en rotation équipé de couteaux montés l'un au-dessus de l'autre, que chaque couteau de l'axe inférieur, passe entre les couteaux de l'axe supérieur leur permettant de se croiser sans se toucher.Between each knife, a space will be left at least equal to the thickness of a knife unit, allowing each axis in rotation equipped with knives mounted one above the other, that each knife of the axis lower, passes between the knives of the upper axis allowing them to cross without touching.

Ce phénomène de cisaillement ainsi créé, permettra de décompresser et d'homogénéiser des fibres ou particules, végétales ou non, sans créer comme sur le système à cardes initialement cité, le phénomène d'amalgame et de tissage de matière sur les axes.This shearing phenomenon thus created, will make it possible to decompress and homogenize fibers or particles, vegetable or not, without creating, as on the carding system initially mentioned, the phenomenon of amalgam and weaving of material on the axes.

Selon des modes particuliers de réalisation :According to particular embodiments:

- un convoyeur automatique permettant l'approvisionnement de fibres ou particules, compressées ou non, végétales ou non, vers l'ensemble axe/couteaux, pourra être décalé vers le bas, ou non par un système de glissières réglables afin d'éviter que ces fibres ou particules ne passent dans le système de couteaux dans cas par exemple d'écorces de pins ou autres fibres ou particules ne soient modifiées avant leur application sur le sol pour garder leur aspect et granulométrie d'origine.- an automatic conveyor allowing the supply of fibers or particles, compressed or not, vegetable or not, to the axis / knives assembly, may be shifted downwards, or not by a system of adjustable slides to prevent these fibers or particles do not pass through the knife system in the case, for example, of pine bark or other fibers or particles are modified before their application on the ground to keep their original appearance and particle size.

- 2 Les dessins annexés illustrent l'invention :- 2 The accompanying drawings illustrate the invention:

La figure 1 représente un type de couteauFigure 1 shows a type of knife

La figure 2 représente en coupe un exemple du système complet de décompactageFigure 2 shows in section an example of the complete decompression system

La figure 3 représente un exemple de dispositif permettant le décalage de la table du convoyeur .FIG. 3 represents an example of a device allowing the shift of the conveyor table.

La figure 4 représente un axe équipé de ses couteaux . En référence à ces dessins, le couteau comporte en son centre un orifice [1] de forme polygonale correspondant à l'axe [2] sur lequel ils seront montés, de taille et de forme identique.Figure 4 shows an axis equipped with its knives. With reference to these drawings, the knife has in its center an orifice [1] of polygonal shape corresponding to the axis [2] on which they will be mounted, of identical size and shape.

Ce même couteau est usiné de manière à avoir à titre d'exemple 5 dents identiques d'attaque (3).This same knife is machined so as to have, for example, 5 identical attack teeth (3).

L'espace entre deux couteaux [4] est au moins égale à l'épaisseur d'un couteau [5]The space between two knives [4] is at least equal to the thickness of a knife [5]

Un deuxième axe complet [6] superposé au premier ( 2] l'entrainement de ses axes se fait à titre d'exemple par poulies, engrenages, chaînes ou système hydraulique.A second complete axis [6] superimposed on the first (2) the driving of its axes is done by way of example by pulleys, gears, chains or hydraulic system.

Le système de convoyeur [7] peut descendre verticalement a son extrémité côté système de dé foisonnement à couteaux [8] à l'aide d'une glissière ou lumière verticale situé de chaque côté du tablier de la machine(9 ] pour laisser un espace suffisant aux fibres ou particules de passer en dessous du système de dé foisonnement à couteaux [8] À titre d'exemple, non limitatif, les couteaux auront un diamètre de l'ordre de 15cm et d'une épaisseur de 8 mm.The conveyor system [7] can descend vertically to its end on the knife overrun system side [8] using a slide or vertical light located on each side of the machine deck (9] to leave a space sufficient for the fibers or particles to pass beneath the knife expansion system [8] By way of non-limiting example, the knives will have a diameter of the order of 15 cm and a thickness of 8 mm.

Le dispositif, selon l'invention, est particulièrement utilisé pour la projection de fibres ou particules, dans le secteur du paysagisme et de l'agriculture.The device according to the invention is particularly used for the projection of fibers or particles, in the landscaping and agriculture sector.
