ARRIERE PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Actuellement, les unités de distribution de gravillons, quelles soient à rouleau distributeur ou extracteur, comiportent toutes essentiellement: un dispositif, adapté pour canaliser la couche de gravillons en sortie du rouleau, constitué d'un déflecteur, ou paroi déflectrice, répartissant de manière uniforme les gravillons sur l'ensemble des couloirs du diffuseur; - le point le plus haut de la tôle galbée en dessous de l'axe du rouleau; - le dessus des cloisons également en dessous de l'axe du rouleau.  Currently, the gravel distribution units, whether with a distributor or extractor roller, all essentially consist of: a device, suitable for channeling the layer of gravel at the outlet of the roller, consisting of a deflector, or deflector wall, distributing uniformly gravel on all the corridors of the diffuser; - the highest point of the curved sheet below the axis of the roller; - the top of the partitions also below the axis of the roller.

Le déflecteur constitue un obstacle sur la trajectoire des gravillons qui a pour effet: - de diminuer la vitesse d'écoulement des gravillons donc la largeur d'épandage sur la chaussée; - de diminuer la fluidité de l'écoulement des gravillons donc du dosage et de la granulométrie.  The deflector constitutes an obstacle on the path of the gravel which has the effect of: - reducing the speed of flow of the gravel therefore the width of spreading on the road; - to decrease the fluidity of the flow of gravel therefore of the dosing and the granulometry.

RESUME DE L'INVENTION L'invention vise à réaliser un dispositif qui élimine lesdits inconvénients en supprimant purement et simplement le déflecteur. Celui-ci est donc remplacé par des cloisons, situées dans le prolongement des cloisons habituellement utilisées, qui s'étendent au dessus de l'axe du rouleau jusqu'à la zone de la couche de gravillons en sortie dudit rouleau. Bien évidemment, la cloison de base et sa partie prolongatrice peuvent constituer une même et seule paroi. Outre l'augmentation de la vitesse d'écoulement des gravillons et de leur fluidité, la préhension des gravillons tout près du rouleau, améliore leur répartition dans les couloirs du diffuseur. PRESENTATION DES DESSINS Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un mode de réalisation préféré de celle-ci donné à titre d'exemple non limitatif et représenté aux dessins annexés. Sur ces dessins: - la figure 1 est une vue de profil en coupe AA de l'unité de distribution de gravillons selon l'état de la technique; - la figure 2 est une vue de profil en coupe AA de l'unité de distribution selon l'invention mettant en évidence le dispositif revendiqué; - la figure 3 est une vue de dessus du rouleau et du diffuseur de gravillons. 15 DESCRIPTION DETAILLEE DE L'INVENTION L'unité de distribution de gravillons pour travaux routiers, représentée aux figures, comprend essentiellement: - un rouleau distributeur ou extracteur (1) de gravillons alimenté par des trappes ou une lame de dosage; - un diffuseur constitué d'une tôle galbée et inclinée (2); d'une pluralité de cloisons (3) solidarisées orthogonalement à ladite tôle (2) et définissant des couloirs (E), à écartement croissant de haut en bas, pour l'écoulement et la répartition des gravillons; d'un support (4), à inclinaison réglable, auquel sont fixées ladite tôle galbée (2) et lesdites cloisons orthogonales (3); - un dispositif (5,3B) adapté pour canaliser la couche de gravillons (G) en sortie du rouleau (1) afin de la distribuer de manière uniforme sur l'ensemble des couloirs (E) du diffuseur (2,3); - un contre diffuseur placé en aval dudit diffuseur. Selon la caractéristique de base de l'invention, le dispositif destiné à 30 canaliser la couche de gravillons (G) en sortie du rouleau (1) est réalisé au moyen de cloisons (3B) situées dans le prolongement des cloisons (3) et s'étendant au dessus de l'axe (X) du rouleau (1) jusqu'à la zone de la couche de gravillons (G) en sortie dudit rouleau. Un tel dispositif remplace le déflecteur communément utilisé qui de ce fait se 35 trouve supprimé. Les cloisons (3) et (3B) ne peuvent former qu'une seule et même cloison. La partie haute de la cloison (3B) comporte une avancée (3C) proche de la couche de gravillons (G) en sortie du rouleau (1). Dans le cas de l'invention, l'arête supérieure du support (4) peut être, d'une part 5 rapprochée du rouleau et, d'autre part, abaissée pour diminuer l'impact des gravillons sur celle-ci. Dans la pratique, le nombre de couloirs est égal au nombre de trappes (14 dans la pratique la plus répandue). Un tel dispositif est adaptable sur tout type de gravillonneur (à benne basculante) 10 pour travaux routier ainsi que sur tout type de machine mixte " gravillonneur épandeur de liant ". Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes, en particulier dans: - les dimensions des rouleaux et le nombre de cloisons du diffuseur; - la conception, la forme et les dimensions des éléments constitutifs des diffuseurs. REVENDICATIONSSUMMARY OF THE INVENTION The invention aims to provide a device which eliminates said drawbacks by purely and simply eliminating the deflector. This is therefore replaced by partitions, located in the extension of the partitions usually used, which extend above the axis of the roller to the area of the gravel layer at the outlet of said roller. Obviously, the basic partition and its extension part can constitute one and the same wall. In addition to increasing the flow speed of the gravel and their fluidity, the gripping of the gravel close to the roller, improves their distribution in the corridors of the diffuser. PRESENTATION OF THE DRAWINGS The characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment of the latter given by way of non-limiting example and shown in the drawings attached. In these drawings: - Figure 1 is a sectional side view AA of the gravel distribution unit according to the state of the art; - Figure 2 is a sectional side view AA of the dispensing unit according to the invention showing the claimed device; - Figure 3 is a top view of the roller and the gravel diffuser. DETAILED DESCRIPTION OF THE INVENTION The gravel distribution unit for road works, shown in the figures, essentially comprises: - a gravel distributor or extractor roller (1) supplied by hatches or a metering blade; - a diffuser made of a curved and inclined sheet (2); a plurality of partitions (3) secured orthogonally to said sheet (2) and defining corridors (E), with increasing spacing from top to bottom, for the flow and distribution of gravel; a support (4), with adjustable inclination, to which are fixed said curved sheet (2) and said orthogonal partitions (3); - a device (5.3B) adapted to channel the layer of gravel (G) at the outlet of the roller (1) in order to distribute it uniformly over all of the corridors (E) of the diffuser (2,3); - a counter diffuser placed downstream of said diffuser. According to the basic characteristic of the invention, the device intended to channel the layer of gravel (G) at the outlet of the roller (1) is produced by means of partitions (3B) situated in the extension of the partitions (3) and s 'extending above the axis (X) of the roller (1) to the area of the gravel layer (G) at the outlet of said roller. Such a device replaces the commonly used deflector which is therefore eliminated. The partitions (3) and (3B) can form only one and the same partition. The upper part of the partition (3B) has a projection (3C) close to the layer of gravel (G) at the outlet of the roller (1). In the case of the invention, the upper edge of the support (4) can be, on the one hand 5 brought closer to the roller and, on the other hand, lowered to reduce the impact of the gravel on it. In practice, the number of lanes is equal to the number of hatches (14 in the most common practice). Such a device is adaptable to any type of gravel spreader (with dump body) 10 for road works as well as to any type of mixed machine "spreader spreader of binder". Of course, the invention is not limited to the embodiments described and shown for which other variants can be provided, in particular in: - the dimensions of the rollers and the number of partitions of the diffuser; - the design, shape and dimensions of the components of the diffusers.
