Description
ta présente invention a pour objet un dispositif pour épandage de liant de terrassement routier ou analogue servant à renforcer la résistance des sols. your present invention relates to a device for spreading binder road or the like used to strengthen the resistance of the soil.
L'épandage de liant pour renforcer la résistance des sols est une technique relativement récente qui consiste à étaler, aussi régulièrement que possible, une fine couche de liant sur le sol pour accroître la résistance globale du terrassement à réaliser. The spreading of binder to reinforce the resistance of the soil is a relatively recent technique which consists in spreading, as regularly as possible, a thin layer of binder on the ground to increase the overall resistance of the earthwork to be carried out.
Le liant utilisé, qui se présente sous forme pulvérulente, est généralement composé de ciment destiné à augmenter la résistance du sol, de chaux vive, destinée à diminuer la teneur en eau, dans un véhicule sans action spécifique, constitué de calcaire ou de limon. The binder used, which is in powder form, is generally composed of cement intended to increase the resistance of the soil, quicklime, intended to decrease the water content, in a vehicle without specific action, consisting of limestone or silt.
L'épandage doit être effectué en quantité juste suffisante pour limiter la consommation d' une matière première dont le prix est relativement élevé. The spreading must be carried out in a quantity just sufficient to limit the consumption of a raw material whose price is relatively high.
Actuellement l'épandage de liant s'effectue à l'aide de machines issues de techniques apparentées. Toutefois ces machines présentent l'inconvénient de ne pas répondre exactement aux besoins inhérents à l'épandage d'un liant de terrassement. Currently the spreading of binder is carried out using machines from related techniques. However, these machines have the disadvantage of not exactly meeting the needs inherent in the spreading of an earthmoving binder.
Les machines actuellement utilisées mettent en effet en oeuvre un tapis vibrant au-dessus duquel le liant est maintenu en lit fluidisé. Cette technique a pour inconvénient de donner lieu à une variation du débit du liant, due à la diminution progressive du poids de la charge de liant contenue dans la cuve placée audessus du lit fluidisé. I1 en résulte une mauvaise qualité du travail ainsi réalisé, l'épandage n'étant pas effectué de manière assez régulière, ainsi qu'une consommation excessive de la quantité de liant mise en oeuvre. The machines currently used in fact use a vibrating belt above which the binder is kept in a fluidized bed. This technique has the drawback of giving rise to a variation in the flow rate of the binder, due to the progressive reduction in the weight of the load of binder contained in the tank placed above the fluidized bed. This results in poor quality of the work thus carried out, the spreading not being carried out fairly regularly, as well as excessive consumption of the amount of binder used.
La présente invention permet de remédier à ces inconvénients en proposant un dispositif permettant de réaliser l'épandage de liant dans les meilleures conditions de régularité et d'économie de matière première. The present invention overcomes these drawbacks by proposing a device for carrying out the spreading of binder in the best conditions of regularity and economy of raw material.
A cet effet, le dispositif selon l'invention comprend une cuve de stockage de liant dont le fond est constitué d'une bande transporteuse sans fin. A l'arrière et en-bas de la cuve, immédiatement au-dessus de la bande transporteuse et sur toute sa largeur, se trouve ménagée une ouverture prolongée par un conduit qui débouche sur un rouleau de distribution placé dans un carter et comportant sur toute sa surface des gprges longitudinales. To this end, the device according to the invention comprises a binder storage tank whose bottom consists of an endless conveyor belt. At the rear and at the bottom of the tank, immediately above the conveyor belt and over its entire width, there is an opening extended by a conduit which leads to a distribution roller placed in a casing and comprising on all its surface of the longitudinal gprges.
L'ensemble est fixé sur un châssis monté sur roues et est attelé à un engin tracteur dont le moteur fournit l'énergie nécessaire, par l'intermédiaire d'une tringlerie et d'un variateur de vitesse, pour faire tourner le rouleau de distribution, dans le sens indiqué par la flèche, de manière que les alvéoles remplies par le haut se vident une par une sur le sol, après avoir été arasées par le càrter. Le rouleau de distribution entraîne par l'intermédiaire d'une chaîne la bande transporteuse qui amène le liant de l'avant à l'arrière de la cuve, en sorte que la rotation dudit rouleau conditionne l'amenée de liant. The assembly is fixed on a chassis mounted on wheels and is coupled to a towing machine, the motor of which supplies the necessary energy, via a linkage and a speed variator, to rotate the distribution roller. , in the direction indicated by the arrow, so that the cells filled from above empty one by one on the ground, after being leveled by the crane. The distribution roller drives the conveyor belt by means of a chain which brings the binder from the front to the rear of the tank, so that the rotation of said roller conditions the supply of binder.
Dans la cuve, à une courte distance au-dessus de la bande transporteuse, est disposé un caillebotis constitué de cornières métalliques, placées transversalement par rapport à la bande transporteuse, angle vers le haut, sur deux niveaux superposés décalés l'un par rapport à l'autre. Ce caillebotis crée des chicanes qui ralentissent la descente du liant, en assurant de ce fait une meilleure répartition sur la bande transporteuse, ledit liant étant introduit dans la cuve par une tuyauterie extérieure. In the tank, a short distance above the conveyor belt, is arranged a grating made of metal angles, placed transversely with respect to the conveyor belt, angle upwards, on two superposed levels offset one relative to the other. This grating creates baffles which slow down the descent of the binder, thereby ensuring a better distribution on the conveyor belt, said binder being introduced into the tank by an external piping.
Le liant se trouve ainsi réparti sur la bande transporteuse grâce au caillebotis, et amené par cette dernière jusque dans le conduit débouchant sur le rouleau de distribution, dont les gorges se remplissent et se vident de liant au fur et à mesure de la rotation dudit rouleau. La quantité de liant répandue sur le sol est fonction de la contenance des gorges, et on peut la modifier en utilisant des rouleaux de distribution différents. A cet effet, le rouleau et le carter qui le renferme sont amovibles. The binder is thus distributed over the conveyor belt thanks to the grating, and brought by the latter as far as the duct leading to the distribution roller, the grooves of which fill and empty of binder as the rotation of said roller . The amount of binder spread on the ground depends on the capacity of the grooves, and can be changed using different distribution rollers. For this purpose, the roller and the casing which contains it are removable.
Les caractéristiques et les avantages de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The characteristics and advantages of the present invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.
L'unique figure du dessin annexé représente une vue de profil et en coupe d'un épandeur de liant selon l'invention. The single figure in the accompanying drawing shows a side view in section of a binder spreader according to the invention.
Si on se réfère à cette figure on voit que l'épandeur de liant comporte un châssis 1 monté sur deux roues, un système d'attelage 12 à un engin tracteur, ainsi qu'une prise de force 13 permettant la transmission de l'énergie du moteur de l'engin tracteur à une boîte de transfert 16 à la sortie de laquelle un pignon 18 transmet à un variateur 14 le mouvement, proportionnellement à la vitesse du pont moteur 17, lequel est relié à la boîte de transfert 16 par l'intermédiaire d'un pignon 19 et d'un arbre 11. If we refer to this figure we see that the binder spreader comprises a frame 1 mounted on two wheels, a coupling system 12 to a towing machine, as well as a PTO 13 allowing the transmission of energy from the engine of the towing vehicle to a transfer box 16 at the output of which a pinion 18 transmits the movement to a variator 14, proportional to the speed of the drive axle 17, which is connected to the transfer box 16 by the through a pinion 19 and a shaft 11.
te châssis 1 est surmonté d'une cuve 5 de stockage de liant, dont le fond est constitué d'une bande transporteuse 3 tendue entre deux rouleaux, 31 à l'avant et 32 à l'arrière, le brin actif de la bande transporteuse 3 passant sur un chemin de glissement 34 constitué d'une plateforme métallique renforcée. A l'arrière et en bas de la cuve 5, juste au-dessus du rouleau 32, une ouverture transversale est prolongée par un conduit transversal 72 solidaire à son extrémité inférieure d'un carter 73 renfermant un rouleau de distribution 7 comportant sur toute sa surface des gorges 71 parallèles à l'axe dudit rouleau. frame 1 is surmounted by a binder storage tank 5, the bottom of which consists of a conveyor belt 3 stretched between two rollers, 31 at the front and 32 at the rear, the active strand of the conveyor belt 3 passing on a sliding path 34 consisting of a reinforced metal platform. At the rear and at the bottom of the tank 5, just above the roller 32, a transverse opening is extended by a transverse duct 72 secured at its lower end to a casing 73 enclosing a distribution roller 7 comprising on all of its surface of the grooves 71 parallel to the axis of said roller.
Le variateur de vitesse 14, par l'intermédiaire d'une pignonnerie 15 et d'une courroie 75, entraîne en rotation l'arbre 74 du rouleau de distribution 7, ce même arbre 74 entraînant à son tour l'arbre 33 du rouleau 32 par l'intermédiaire d'une chaîne 36. The variable speed drive 14, by means of a pinion 15 and a belt 75, rotates the shaft 74 of the distribution roller 7, this same shaft 74 in turn driving the shaft 33 of the roller 32 through a chain 36.
Dans la cuve 5 sont disposées sur deux niveaux 41 et 42 des cornières métalliques 4, placées transversalement, angles vers le haut, et décalées les unes par rapport aux autres. In the tank 5 are arranged on two levels 41 and 42 metal angles 4, placed transversely, angles upward, and offset from each other.
A l'avant et en bas de la cuve 5, l'étanchéité entre la bande transporteuse et la paroi verticale antérieure de la cuve est assurée par un joint transversal 35. At the front and at the bottom of the tank 5, the seal between the conveyor belt and the front vertical wall of the tank is ensured by a transverse joint 35.
Le remplissage de la cuve 5 peut s'effectuer à l'aide d'air comprimé par une tuyauterie extérieure dont l'extrémité 6 débouche à l'avant et en haut de la cuve. The filling of the tank 5 can be carried out using compressed air by an external piping whose end 6 opens out at the front and at the top of the tank.
