Abstract

L'invention concerne un dispositif destiné à libérer la rotation d'une porte de commande de décharge de matières en particules. Elle comporte des supports fixés sur la paroi du récipient de chaque côté de l'ouverture de décharge. Ces supports sont divisés en deux parties, la partie inférieure pouvant descendre par rapport à la partie supérieure, sous l'effet d'une pièce en forme de came. Cette disposition permet ainsi de régler le jeu entre la porte et les bords de l'ouverture afin d'eviter tout coincement par des poussières accumulées. L'invention s'applique notamment à des wagons à trémie.The invention relates to a device for releasing the rotation of a particulate matter discharge control door. It has brackets fixed to the wall of the container on either side of the discharge opening. These supports are divided into two parts, the lower part being able to descend relative to the upper part, under the effect of a cam-shaped part. This arrangement thus makes it possible to adjust the clearance between the door and the edges of the opening in order to avoid any jamming by accumulated dust. The invention applies in particular to hopper wagons.
