Comme on 1'a précisé ci-dessus, l'invention met en oeuvre la vis d'une tarière de foreuse entant que vis de malaxeur à béton. Sur la figure 1, on a représenté à titre d'exemple non limitatif une tarière désignée dans son ensemble par la référence 10, montée sur un bras de manutention 12 et dont la vis 14 est entraînée par un moteur 16, à l'aide d'un arbre 18. Selon l'invention, on adapte autour de la vis de la tarière 10 une cuve 20 de configuration particulière de maniera à réaliser un malaxeur à béton tel que représenté sur la figure 2,
Cette cuve 20 se présente sous la forme d'un récipient cylindrique ouvert à chacune de ses extrémités de minière à recevoir la vis de la tarière l'ouverture supérieure étant traversée par l'arbre 18 entraînant la vis.Cette cuve cylindrique 20 est montée sur le bras de manutention 12 de la tarière par l'intermédiaire d'un support qui, dans l'exemple de réalisation illustré par la figure 2, est constitué par un étrier 22.As specified above, the invention uses the auger auger screw as a concrete mixer screw. In Figure 1, there is shown by way of nonlimiting example an auger designated as a whole by the reference 10, mounted on a handling arm 12 and whose screw 14 is driven by a motor 16, using d a shaft 18. According to the invention, a tank 20 of particular configuration is adapted around the auger screw 10 so as to make a concrete mixer as shown in FIG. 2,
This tank 20 is in the form of a cylindrical container open at each of its mining ends to receive the auger screw, the upper opening being traversed by the shaft 18 driving the screw. This cylindrical tank 20 is mounted on the handling arm 12 of the auger by means of a support which, in the embodiment illustrated by FIG. 2, consists of a stirrup 22.
Le fond de la cuve 20 est pourvu d'un organe d'obturation mobile constitué de deux coquilles 24, 24' articulées sur la jupe de la cuve 20 par l'intermédiaire d'axes 26, 26', parallèles l'un à l'autre et perpendiculaires à l'axe longitudinal de la cuve. Chacune des coquilles 24, 24' peut etre manoeuvrée par un vérin tel que 28, dont le cylindre est articulé sur la jupe de la cuve à l'aide d'une chape 30 et la tige sur la coquille correspondante également à l'aide d'une chape 32, de manière à pouvoir faire passer les coquilles de la position d'ouverture à la position de fermeture et vice-versa. The bottom of the tank 20 is provided with a movable closure member constituted by two shells 24, 24 'articulated on the skirt of the tank 20 by means of axes 26, 26', parallel to each other. 'other and perpendicular to the longitudinal axis of the tank. Each of the shells 24, 24 'can be operated by a jack such as 28, the cylinder of which is articulated on the skirt of the tank using a yoke 30 and the rod on the corresponding shell also using 'a yoke 32, so as to pass the shells from the open position to the closed position and vice versa.
Selon l'invention, (figure 5), la jupe de la cuve 20 comporte dans sa capacité interne des ailettes 34 au nombre de quatre dans cet exemple non limitatif, qui s'opposent à l'hélice de la vis de malaxage 14 de manière à permettre au béton, comme on le verra ci-après, de circuler sur la périphérie de la jupe sans être entraîné en rotation par la vis. According to the invention (FIG. 5), the skirt of the tank 20 has in its internal capacity fins 34 four in number in this nonlimiting example, which oppose the helix of the kneading screw 14 so to allow the concrete, as will be seen below, to circulate on the periphery of the skirt without being driven in rotation by the screw.
L'utilisation du malaxeur à béton ansi constitué dès que la cuve cylindrique 20 est fixée sur le bras 12 ou équivalent, comprend les trois phases décrites ci-après. cette description se réfère, à titre d'exemple non limitatif, au bétonnage des poteaux électriques P dans leurs fouilles F, la tarière 10 utilisée servant successivement s effectuer cette fbuilie puis à malaxer le béton. The use of the concrete mixer ansi formed as soon as the cylindrical tank 20 is fixed on the arm 12 or equivalent, comprises the three phases described below. this description refers, by way of nonlimiting example, to the concreting of the electric poles P in their excavations F, the auger 10 used successively for carrying out this fbuilie then mixing the concrete.
1- Chargement
Pour assurer le chargement en agrégats A (figure 3), il suffit d'amener les coquilles 24, 24' en position d'ouverture par manoeuvre des vérins tels que 28 de manière à dégager le fond de la cuve 20 et à faire tourner la vis 14 de la tarière dans le sens du vissage, le malaxeur étant positionné sur le tas d'agrégats A. Dès que le remplissage de la cuve 20 est achevé, on actionne les vérins 28 pour refermer les coquilles 24, 24' et obturer le fond de la cuve 20.1- Loading
To ensure the loading of aggregates A (FIG. 3), it suffices to bring the shells 24, 24 ′ into the open position by actuating the jacks such as 28 so as to release the bottom of the tank 20 and to rotate the auger screw 14 in the screwing direction, the mixer being positioned on the aggregate pile A. As soon as the filling of the tank 20 is completed, the jacks 28 are actuated to close the shells 24, 24 'and close the tank bottom 20.
2 Malaxage
Après l'opération de remplissage décrite ci-dessus, les coquilles 24, 24' étant maintenues en position de fermeture, on relève la cuve 20 pour la dégager du tas d'agregats (figure 4) et tout en continuant à ihire tourner la vis 14 de la tarière pour malaxer les agrégats contenus dans la cuve 20, on introduit l'eau et le ciment par l'ouverture supérieure de la cuve. Ainsi qu'on l'a précise cidessus, les ailettes 34 s'opposent à la vis 14 et elles permettent au béton de circuler sur la périphérie de la cuve sans être entraîné en rotation par la vis 14 de la tarière.2 Mixing
After the filling operation described above, the shells 24, 24 'being maintained in the closed position, the tank 20 is raised to release it from the pile of aggregates (FIG. 4) and while continuing to turn the screw 14 of the auger to knead the aggregates contained in the tank 20, water and cement are introduced through the upper opening of the tank. As specified above, the fins 34 oppose the screw 14 and they allow the concrete to circulate on the periphery of the tank without being driven in rotation by the screw 14 of the auger.
3. Déchargement
Dès que l'opération de malaxage est terminée, il suffit pour evacuer le béton malaxé contenu dans la cuve 20 d'ouvrir l'une ou l'autre des coquilles 24, 24' ou les deux et de faire tourner la vis 14 dans le sens inverse de celui utilisé pour le chargement et le malaxage, ce qui aide au déchargement. Sur la figure 6, on a représenté l'opération de déchargement du béton malaxé dans la fouille F, préalablement pratiquée dans le sol par la vis 14 de la tarière, pour assurer le bétonnage d'un poteau électrique P. Dans cette application non limitative, seule la coquille 24 est relevée, la coquille 24' restant en position de fermeture, ce qui assure un guidage du béton s'ecoulant de la cuve.3. Unloading
As soon as the mixing operation is completed, it suffices to remove the mixed concrete contained in the tank 20 to open one or the other of the shells 24, 24 'or both and to turn the screw 14 in the opposite direction to that used for loading and mixing, which helps unloading. In Figure 6, there is shown the operation of unloading the mixed concrete into the excavation F, previously performed in the ground by the screw 14 of the auger, to ensure the concreting of an electric pole P. In this non-limiting application , only the shell 24 is raised, the shell 24 'remaining in the closed position, which ensures guidance of the concrete flowing from the tank.
Il demeure bien entendu que cette invention n'est pas limitée aux exemples de réalisation ou d'application décrits ci-dessus mais qu'elle en englobe toutes les variantes. It remains to be understood that this invention is not limited to the exemplary embodiments or applications described above but that it encompasses all variants thereof.
