Abstract

The distributor consists of a hopper (1) which contains the unset concrete. The hopper has a lower part (3) with parallel sides, and a central opening (12) in the bottom. The opening is set over the mould (16). The hopper has a rectangular section and is fitted in the lower part with two parallel paddle wheels (10) with radial paddle blades (11). A third paddle (15) is mounted centrally above them. The paddles are geared together at the outside of the hopper and are driven by a single motor. The sides of the bottom of the hopper are rounded.

Description

La présente invention concerne les trémies positionnées à l'aplomb des moules pour la fabrication de toute pièce en béton arme. The present invention relates to hoppers positioned directly above the molds for the manufacture of any piece of reinforced concrete.

Dans les dispositifs connus de ce genre, les trémies ont généralement des ouvertures inférieures qui sont fermées par des trappes actionnées manuellement par des serins hydrauliques ou pneumatiques. Ce système possède l'inconvénient de -manquer de précision dans l'écoulement du béton, et bien souvent ce dernier se tasse au fond de la trémie. In known devices of this kind, the hoppers generally have lower openings which are closed by hatches actuated manually by hydraulic or pneumatic cylinders. This system has the disadvantage of lacking precision in the flow of concrete, and very often the latter settles at the bottom of the hopper.

Le dispositif suivant l'invention permet d'éviter ces inconvénients ; en effet, lVécoulement du béton se fait réguliè rement et peut être dosé de manière précise. Il permet également d'obtenir un matériau de composition et densité homogène. The device according to the invention makes it possible to avoid these drawbacks; in fact, the flow of concrete is done regularly and can be precisely dosed. It also makes it possible to obtain a material of homogeneous composition and density.

Le dispositif, objet de l'invention, comporte une trémie positionnée par tout moyen approprié au-dessus des moules, coffrage, support définitif à alimenter en matériau.  The device, object of the invention, comprises a hopper positioned by any appropriate means above the molds, formwork, final support to be supplied with material.

La trémie comporte en partie inférieure un carter renfermant deux arbres à pales positionnés sur un même plan horizontal. Les deux arbres tournent vers llexterieur en sens opposé de manière à extraire du matériau de la trémie pour le déverser par l'intermédiaire de l'ouverture inférieure du carter. Les pales sont solidarisées sur toute leur longueur sur leurs arbres porteurs de façon à faire étanchéité à l'arrêt. Les pales sont disposées de façon qu'elles soient imbriquées sans se toucher pour fermer l'espace se trouvant entre les deux arbres. The hopper has in the lower part a casing containing two paddle shafts positioned on the same horizontal plane. The two shafts rotate towards the outside in opposite directions so as to extract material from the hopper to pour it out via the lower opening of the casing. The blades are secured over their entire length on their load-bearing shafts so as to seal when stationary. The blades are arranged so that they overlap without touching to close the space between the two shafts.

Un troisième arbre rotatif facultatif est fixé au-dessus des deux arbres à pales et est muni de griffes, pour éviter toute formation de voûte. Les différents arbres sont actionnés par un moto-réducteur variateur par l'intermédiaire de paliers et pignons. An optional third rotating shaft is attached above the two paddle shafts and has claws to prevent arching. The various shafts are actuated by a variator motor-reducer by means of bearings and pinions.

Selon une réalisation préférentielle, les pales peuvent être fabriquées en polyuréthane ou en acier. According to a preferred embodiment, the blades can be made of polyurethane or steel.

Les dessins annexés aux présentes illustrent à titre d'exemple non limitatif un mode de réalisation du dispositif conforme à la présente invention. The drawings appended hereto illustrate by way of nonlimiting example an embodiment of the device according to the present invention.

La figure 1 représente une coupe succinte de la trémie. Figure 1 shows a brief section of the hopper.

La figure 2 représente une vue de dessus suivant l'axe
AA porté sur la figure 1. Figure 2 shows a top view along the axis
AA shown in Figure 1.

La figure 3 représente une perspective de la partie dessinée en figure 2. FIG. 3 represents a perspective of the part drawn in FIG. 2.

La figure 4 représente une coupe des arbres avec pales. Figure 4 shows a section of the trees with blades.

Tel qu'il est représenté en figures 1,2,3 et 4, le dispositif comporte une trémie 1 dans laquelle sont déversés des matériaux 2 qui descendent jusqu'au carter 3 aux côtés 4 transversaux arrondis éliminant des angles de retenue. A l'une des extrémités, dudit carter est fixé un moto-réducteur 5 qui actionne par le ttuchement de deux pignons 6 et 7 des paliers 8 et 9 les arbres 10 portant lespales 11 ; ces dernières prennent du matériau et le font glisser le long des parois 4 arrondies jusqu'à ltouverture 12 inférieure tombant ensuite dans le moule 16. L'ouverture 12 est égale à la longueur des ralles. Les pales 11 sont prises à leur base en sandwich entre deux: tiges 13 plates qui sont solidarisées à l'arbre 10 par soudure. Un troisième arbre 14 doté de griffes 15 est actionné par le moto-réducteur facilitant un bon écoulement des matériaux sur les pales. As shown in Figures 1,2,3 and 4, the device comprises a hopper 1 into which materials 2 are poured which descend to the casing 3 with rounded transverse sides 4 eliminating retaining angles. At one end of said housing is fixed a gear motor 5 which actuates by the ttuchement of two pinions 6 and 7 of the bearings 8 and 9 the shafts 10 carrying the blades 11; the latter take material and slide it along the rounded walls 4 to the lower opening 12 then falling into the mold 16. The opening 12 is equal to the length of the ralles. The blades 11 are sandwiched at their base between two: flat rods 13 which are secured to the shaft 10 by welding. A third shaft 14 provided with claws 15 is actuated by the geared motor facilitating a good flow of materials on the blades.

Le dispositif, objet de l'invention, peut etre utilisé tout particulièrement pour manipuler des matériaux de construction.  The device, object of the invention, can be used very particularly for handling construction materials.
