Description

ASPIRO-BROYEUR DE FEUILLES, BRANCHAGES ET DETRITUS
La présente invention concerne un dispositif pour aspirer après broyage les débris de végétation divers, ainsi que les détritus que l'on trouve dans les fossés, le long des routes, ou de manière générale dans les espaces publics.SHEET ASPIRATOR, LEAF BRANCHES AND DETRITUS
The present invention relates to a device for vacuuming after grinding the debris of various vegetation, as well as the detritus that is found in ditches, along roads, or in general in public spaces.

L'accumulation de ces débris divers empêche le bon écoulement des eaux de pluie, présente un danger d'incendie, de pollution et possède un caractère inesthétique certain.The accumulation of this various debris prevents the good flow of rainwater, presents a fire, pollution hazard and has a certain unsightly character.

Les pouvoirs publics ou les gestionnaires de ces lieux, ont naturellement le souci d'enlever ces accumulations par divers moyens.The public authorities or the managers of these places naturally take care to remove these accumulations by various means.

Les plus fréquemment utilisés sont - Les sytèmes aspirateurs, munis d'un tuyau flexible dont l'extrémité est dirigée manuellement ou mécaniquement vers les déchets ; mais les branchages ou détritus volumineux obstruent fréquemment la machine, obligeant l'opérateur à des démontages incessants. De plus, lorsque les déchets sont accumulés depuis plusieurs mois et imbibés d'eau de pluie dans les fossés par exemple, un aspirateur a le plus grand mal à disjoindre les plaques ou paquets ainsi créés.The most frequently used are - Vacuum systems, fitted with a flexible hose, the end of which is directed manually or mechanically towards the waste; but bulky branches or detritus frequently obstruct the machine, forcing the operator to incessant disassembly. In addition, when the waste has been accumulated for several months and soaked with rainwater in the ditches for example, a vacuum cleaner has the greatest difficulty in disjoining the plates or packages thus created.

- les systèmes utilisant la rotation de lames de coupes diverses pour couper ou déchiqueter, avant aspiration ; celles-ci parviennent à disjoindre les paquets de déchets accumulés avant leur aspiration vers une benne de stockage, mais là aussi des branchages ou paquets compacts de déchets, ou des détritus de matière ou de forme spéciale parviennent à se placer entre la lame en rotation et la bouche d'aspiration, provoquant ainsi le colmatage de cette dernière et/ou du tuyau d'aspiration, par le fait que l'outil n'a pu réduire suffisamment leur taille.- systems using the rotation of various cutting blades to cut or shred, before aspiration; these manage to separate the bundles of waste accumulated before their aspiration towards a storage bucket, but here too branches or compact bundles of waste, or detritus of material or of special shape manage to be placed between the rotating blade and the suction mouth, thus causing clogging of the latter and / or of the suction pipe, by the fact that the tool could not reduce their size sufficiently.

La présente invention permet de remédier à ces inconvénients. Elle comporte en effet un outil en rotation composé d'une chaine se terminant éventuellement par un fléau métallique, ou plus généralement de tout outil de coupe articulé, l'extrémité de cet outil en rotation autour de son axe décrivant la surface d'une sphère, la bouche d'aspiration étant placée à l'intersection du tuyau d'aspiration et de cette sphère
De cette manière, la rotation de l'outil décrivant toute la surface de la bouche d'aspiration empêchera tout colmatage de celle-ci, et donc du tuyau d'aspiration, par déchiquetage ou expulsion des déchets volumineux ou non débitables.The present invention overcomes these drawbacks. It indeed comprises a rotating tool composed of a chain possibly ending in a metal beam, or more generally of any articulated cutting tool, the end of this tool in rotation about its axis describing the surface of a sphere , the suction mouth being placed at the intersection of the suction pipe and this sphere
In this way, the rotation of the tool describing the entire surface of the suction mouth will prevent any clogging of the latter, and therefore of the suction pipe, by shredding or expulsion of bulky or non-debitable waste.

On constate que la souplesse de l'outil de coupe en rotation, allié à la proximité immédiate de la bouche d'aspiration par rapport à l'extrémité de cet outil, produit le double effet recherché de broyage et de nettoyage de l'extrémité du tuyau d'aspiration. On remarque que l'outil de coupe pénètre généralement au-delà de la surface définie par le contour fermé de la bouche d'aspiration.It can be seen that the flexibility of the rotating cutting tool, combined with the immediate proximity of the suction mouth relative to the end of this tool, produces the desired double effect of grinding and cleaning the end of the suction hose. Note that the cutting tool generally penetrates beyond the surface defined by the closed contour of the suction mouth.

En pratique, la bouche d'aspiration se situera à moins de dix cm de la surface de la sphère décrite par l'extrémité, de l'outil, de préférence à moins de cinq centimètres, plus particulièrement à moins de deux centimètres, de même cette distance étant définie sur un axe passant par l'extrémité de l'outil et le centre de la sphère. De même il existera généralement un carter dont un plan est perpendiculaire à l'axe de rotation de l'outil, qui limite la sphère décrite par l'outil à ce plan. In practice, the suction mouth will be located less than ten cm from the surface of the sphere described by the end of the tool, preferably less than five centimeters, more particularly less than two centimeters, likewise this distance being defined on an axis passing through the end of the tool and the center of the sphere. Likewise, there will generally be a casing whose plane is perpendicular to the axis of rotation of the tool, which limits the sphere described by the tool to this plane.

Les autres côtés du carter contribuent à créer les conditions d'une bonne aspiration par la turbine d'aspiration.The other sides of the housing help to create the conditions for good suction by the suction turbine.

La bouche d'aspiration sera donc, dans ce cas, réalisée à l'intersection du tuyau d'aspiration et de ce carter, à la distance déjà indiquée de l'extrémité de l'outil en rotation.The suction mouth will therefore, in this case, be made at the intersection of the suction pipe and this casing, at the distance already indicated from the end of the rotating tool.

Selon des modes particuliers de réalisation : l'axe portant l'outil sera vertical ou horizontal, et il sera entraîné mécaniquement ou hydrauliquement ; l'extrémité de la bouche d'aspiration sera tangente au carter dans la zone ou l'outil passe au début de sa rotation devant cette bouche, afin de favoriser l'écoulement dynamique du flux de déchets ; l'outil de broyage sera placé à l'extrémité d'un bras articulé hydrauliquement par exemple, de manière à pouvoir intervenir dans une zone large à partir du véhicule portant l'ensemble de broyage et d'aspiration et tractant la remorque de stockage.According to particular embodiments: the axis carrying the tool will be vertical or horizontal, and it will be driven mechanically or hydraulically; the end of the suction mouth will be tangent to the casing in the area where the tool passes at the start of its rotation in front of this mouth, in order to promote the dynamic flow of the waste stream; the grinding tool will be placed at the end of a hydraulically articulated arm for example, so as to be able to intervene in a wide area from the vehicle carrying the grinding and suction assembly and towing the storage trailer.

L'invention permet ainsi de disposer d'un véhicule muni d'un aspiro-broyeur capable de déchiqueter et aspirer les déchets vers une cuve de stockage au moyen d'une turbine et d'un outil de coupe à chaine, conçu pour éviter tout colmatage du tuyau d'aspiration
Les dessins annexés illustrent un mode préféré de réalisation de l'invention avec axe d'outil vertical.The invention thus makes it possible to have a vehicle provided with a vacuum-shredder capable of shredding and sucking the waste towards a storage tank by means of a turbine and a chain cutting tool, designed to avoid any clogging of the suction hose
The accompanying drawings illustrate a preferred embodiment of the invention with a vertical tool axis.

La figure 1, représente en vue perspective, le dispositif de broyage, le début du tuyau d'aspiration et l'extrémité du bras de manipulation.Figure 1 shows in perspective view, the grinding device, the start of the suction pipe and the end of the handling arm.

La figure 2 représente le dispositif de broyage et le début du tuyau d'aspiration, vu de dessus. Figure 2 shows the grinding device and the start of the suction hose, seen from above.

La figure 3 représente le dispositif représenté à la figure 2, vu en élévation.Figure 3 shows the device shown in Figure 2, seen in elevation.

En référence à ces dessins, le dispositif comporte un outil de coupe (1) comprenant un axe (2) et des chaines (3) munies éventuellement à leur extrémité de fléaux (4). L'entraînement de cet axe en rotation est réalisé par des moyens mécaniques ou hydrauliques, non représentés. Pendant la rotation l'extrémité des chaines (3) ou du fléau (4) décrit une sphère (5), limitée en pratique par la partie horizontale (6) du carter de protection, et par le sol d'autre part.With reference to these drawings, the device comprises a cutting tool (1) comprising an axis (2) and chains (3) optionally provided with flails (4) at their end. The drive of this axis in rotation is carried out by mechanical or hydraulic means, not shown. During rotation, the end of the chains (3) or of the beam (4) describes a sphere (5), limited in practice by the horizontal part (6) of the protective casing, and by the ground on the other hand.

La bouche d'aspiration (7), intersection du tuyau d'aspiration (8) et des surfaces (6) et (9) composant le carter se trouve placée à proximité immédiate de cette sphère (5), de manière à ce que l'outil (1) en passant régulièrement devant toute la surface de la bouche (7), broie ou éjecte tout bloc de déchet ou détritus qui aurait réussi à se glisser entre l'outil (1) et la bouche (7) sans être broyé au préalable.The suction mouth (7), intersection of the suction pipe (8) and the surfaces (6) and (9) composing the housing is placed in the immediate vicinity of this sphere (5), so that the tool (1) regularly passing in front of the entire surface of the mouth (7), grinds or ejects any block of waste or detritus which would have managed to slip between the tool (1) and the mouth (7) without being crushed beforehand.

La bouche d'aspiration peut avoir des formes diverses, suivant la forme du carter et celle du tuyau d'aspiration : cependant, il est essentiel selon l'invention que la ligne d'intersection du carter et du tuyau d'aspiration définissant cette bouche soit très près de la surface de la sphère décrite par l'extrémité de la chaine (3) ou du fléau (4). L'invention est particulièrement destinée à la récolte des déchets de végétation et des détritus le long des routes ou sur les espaces de plein air. The suction mouth can have various shapes, depending on the shape of the housing and that of the suction pipe: however, it is essential according to the invention that the line of intersection of the housing and the suction pipe defining this mouth either very close to the surface of the sphere described by the end of the chain (3) or of the beam (4). The invention is particularly intended for the collection of vegetation waste and litter along roadsides or in open air spaces.
