A seal (9) extends between the edge of the suction fan and the recess (10) in the grid that houses it.

Description

La présente invention concerne un dispositif d'aspiration pour balayeuse urbaine automobile et plus particulièrement un perfectionnement au dispositif décrit dans le brevet FR 88 01484, elle concerne également les balayeuses équipées du dispositif. The present invention relates to a suction device for an automobile urban sweeper and more particularly to an improvement to the device described in patent FR 88 01484, it also relates to sweepers equipped with the device.

Une balayeuse décrite dans le brevet dessus est constituée d'un châssis, d'une cabine de conduite, d'une benne de collecte des déchets fixée au châssis et d'une turbine d'aspiration d'axe vertical fixée sur le dessus du plafond mobile de la benne de collecte. Ledit plafond mobile portant la turbine est relié élastiquement à la benne par un couvre joint élastique. A sweeper described in the above patent consists of a chassis, a driving cab, a waste collection bucket attached to the chassis and a vertical axis suction turbine attached to the top of the ceiling. mobile of the collection bucket. Said movable ceiling carrying the turbine is connected elastically to the bucket by an elastic joint cover.

Cette construction a permis d'améliorer considérablement la stabilité et l'insonorisation du véhicule. This construction considerably improved the stability and the soundproofing of the vehicle.

Cependant on a observé dans le temps un écrasement du joint élastique entourant le plafond mobile, une transmission des vibrations à la benne de collecte et une utilisation insuffisante du volume à disposition. However, over time, there has been a crushing of the elastic seal surrounding the movable ceiling, transmission of vibrations to the collection bucket and insufficient use of the volume available.

Afin de conserver tous les avantages de la construction antérieure tout en supprimant l'inconvénient précité, la demanderesse a eu l'idée d'inverser la position de la turbine. In order to retain all the advantages of the previous construction while eliminating the aforementioned drawback, the applicant has had the idea of reversing the position of the turbine.

Le but de l'invention est de proposer un dispositif qui conserve tous les avantages de la construction antérieure de la balayeuse du brevet FR 88 01484 et qui utilise les avantages de la turbine inversée. The object of the invention is to provide a device which retains all the advantages of the prior construction of the sweeper of patent FR 88 01484 and which uses the advantages of the inverted turbine.

La position inversée de la turbine permet de surélever le niveau d'aspiration pour diminuer le volume perdu au-dessus de la cuve, d'augmenter le volume d'aspiration pour diminuer la résistance de l'air. The inverted position of the turbine allows to raise the suction level to decrease the volume lost above the tank, to increase the suction volume to decrease the air resistance.

Plus particulièrement, I'invention consiste en un dispositif d'aspiration pour balayeuse urbaine automobile comportant une cuve à déchets fermée par un plafond mobile, la turbine d'aspiration étant d'axe vertical et placée au-dessus de la cuve, caractérisé en ce qu'il comporte une surface perforée sensiblement horizontale dans laquelle est montée la turbine sur une pluralité de paliers hydrauliques, et en ce que ladite surface perforée est positionnée parallèlement au plafond mobile de manière à créer un volume d'aspiration, et en ce que le positionnement de la turbine est tel que la face d'aspiration de la turbine est sensiblement dans le plan de la surface perforée. More particularly, the invention consists of a suction device for an automobile street sweeper comprising a waste tank closed by a movable ceiling, the suction turbine being of vertical axis and placed above the tank, characterized in that that it comprises a substantially horizontal perforated surface in which the turbine is mounted on a plurality of hydraulic bearings, and in that said perforated surface is positioned parallel to the movable ceiling so as to create a suction volume, and in that the positioning of the turbine is such that the suction face of the turbine is substantially in the plane of the perforated surface.

On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux figures annexées suivantes - figure 1: vue en coupe verticale d'une première variante de réalisation de balayeuse selon l'invention - figure 2 : vue de dessus de la turbine de la figure 1 - figure 3 : vue en coupe verticale d'une deuxième variante de réalisation - figure 4 : vue de dessus de la turbine de la figure 3. The invention will be better understood using the following description made with reference to the following appended figures - FIG. 1: vertical section view of a first embodiment of a sweeper according to the invention - FIG. 2: top view of the turbine of FIG. 1 - FIG. 3: view in vertical section of a second alternative embodiment - FIG. 4: top view of the turbine of FIG. 3.

On se reporte d'abord aux figures 1 et 2 correspondant à une première variante de balayeuse comportant une cuve à déchets (3) et une turbine à axe vertical (1).  Reference is first made to FIGS. 1 and 2 corresponding to a first variant of a sweeper comprising a waste tank (3) and a turbine with a vertical axis (1).

Conformément à l'inventlon, la turbine (1) est inversée et encastrée dans une grille (4) de la cuve (3) comportant un logement de turbine (10) dans lequel la turbine est montée sur trois paliers hydrauliques (2) arrêtant les vibrations. De préférence, la grille de filtration (4) est solidarisée au plafond mobile (8) par tout moyen (9). According to the inventlon, the turbine (1) is inverted and embedded in a grid (4) of the tank (3) comprising a turbine housing (10) in which the turbine is mounted on three hydraulic bearings (2) stopping the vibrations. Preferably, the filtration grid (4) is secured to the movable ceiling (8) by any means (9).

Le positionnement de la turbine est tel que la surface d'aspiration de la turbine (1) est préférentiellement sensiblement dans le plan de la grille (4) ou dans un plan inférieur au plan de la grille. The positioning of the turbine is such that the suction surface of the turbine (1) is preferably substantially in the plane of the grid (4) or in a plane lower than the plane of the grid.

Cette disposition permet d'une part d'abaisser l'entrée de la turbine, augmentant ainsi le volume d'aspiration (5) disponible entre ladite turbine et le plafond mobile (8) du véhicule pour une résistance minimale d'aspiration, et d'autre part de conserver un seuil de remplissage (4) très haut pour un volume de remplissage maximum. This arrangement allows on the one hand to lower the inlet of the turbine, thus increasing the suction volume (5) available between said turbine and the movable ceiling (8) of the vehicle for minimum suction resistance, and d on the other hand to keep a very high filling threshold (4) for a maximum filling volume.

Dans cette variante un joint circulaire (9) entoure la turbine, la relie à la périphérie du logement, et empêche le dépôt de poussières fines entre le logement (10) et la turbine (1). In this variant a circular seal (9) surrounds the turbine, connects it to the periphery of the housing, and prevents the deposition of fine dust between the housing (10) and the turbine (1).

Par ailleurs, l'étanchéité réalisée à la sortie soufflante (6) de la turbine grâce à un tuyau flexible (7) supprime la transmission des vibrations au réservoir (3) et la pression sur le joint d'étanchéité. Furthermore, the seal produced at the blower outlet (6) of the turbine using a flexible pipe (7) eliminates the transmission of vibrations to the tank (3) and the pressure on the seal.

Selon une autre variante de l'invention, représentée sur les figures 3 et 4 les trois paliers hydrauliques (2) sont portés par trois supports (11) fixés à la cuve (3). According to another variant of the invention, shown in Figures 3 and 4 the three hydraulic bearings (2) are carried by three supports (11) fixed to the tank (3).

Le joint (9) est supprimé, les autres éléments étant inchangés. The seal (9) is deleted, the other elements being unchanged.

Bien entendu la grille peut être remplacée par toute autre surface perforée. Of course the grid can be replaced by any other perforated surface.

Les avantages de l'invention sont importants et sont notamment les suivants: - augmentation du volume d'aspiration - efficacité de l'aspiration - diminution des vibrations  The advantages of the invention are significant and are in particular the following: - increase in the suction volume - efficiency of the suction - reduction in vibrations
