Abstract

a. Dispositif pour l'ouverture et la fermeture automatique de portes d'obturation de trémies. b. Dispositif caractérisé en ce qu'il comporte des moyens de blocage des portes en position fermée coopérant avec des organes de liaison mécaniques permettant d'effectuer automatiquement l'ouverture des portes ou leur verrouillage, en position de fermeture en réponse à un ordre extérieur ainsi que des organes hydropneumatiques permettant de récupérer l'énergie libérée lors de l'ouverture des portes et du déchargement des trémies afin de la réutiliser pour effectuer leur fermetureat. Device for automatic opening and closing of hopper shut-off doors. b. Device characterized in that it comprises means for locking the doors in the closed position cooperating with mechanical connecting members making it possible to automatically open the doors or their locking, in the closed position in response to an external order as well as hydropneumatic devices to recover the energy released when opening the doors and unloading the hoppers in order to reuse it to close them
