Abstract

L'invention se rapporte à une installation composée d'une machine de travail, telle qu'un broyeur ou un séparateur à tamis vibrant, montée sur le chassis d'un véhicule pouvant circuler sur la voie publique. Cette installation est pourvue: d'une trémie réceptrice (14) montée sur la partie antérieure du châssis (10) du véhicule et comportant une ouverture supérieure destinée à recevoir les objets à traiter et un conduit de sortie (18) faisant face au côté postérieur du châssis du véhicule; d'un alimentateur (24) servant à décharger les objets contenus dans la trémie par le conduit de sortie (18); un transporteur monté en pont (22) fixé à la partie médiane du châssis et dirigé vers son côté postérieur, tout en s'inclinant vers le haut, et servant à décharger les objets amenés par l'alimentateur à sortir par le conduit de sortie (18) de la trémie; d'une machine de travail (16) montée sur le côté postérieur du châssis de façon à recevoir les objets tombant depuis l'extrémité postérieure du transporteur monté en pont (22) et destinée à soumettre lesdits objets aux traitements physiques requis, tels qu'un broyage et un tamisage; d'un transporteur de sortie (28) servant à décharger les objets traités par la machine de travail vers l'extérieur du châssis du véhicule; et d'un dispositif de commande de vitesse (39) servant à moduler la vitesse de l'alimentateur (24) et du transporteur monté en pont (22).
