Title
(EN) A MEANS FOR DISCHARGING PARTICLE MATERIAL
(FR) MOYEN DE DECHARGE DE MATIERES PARTICULAIRES
Abstract
(EN)
A means for discharging particle material from a container (1) with a table (15) to support the particle material in the container, comprising a feed unit (19) which is movable on the table for discharging the material through a peripherical outlet opening (18), and drive means (20) for driving the feed unit (19), said feed unit having feeding surfaces (28, 30) extending all around the table (15). According to the invention the feed unit (19) comprises at least two spaced feeding elements (22, 23, 24) disposed to successively move the material in direction from the centre part of the table towards the outlet opening. The feeding elements are arranged, during a full cycle of movement of the feed unit to be alternately active within an arbitrary section of the table (15) extending between the centre part and outlet opening (18) for feeding layer of particle material in front of them in the direction to the outlet opening, and inactive while returning to a starting position.
(FR)
Le moyen de décharge de matières particulaires contenues dans un récipient (1), qui est muni d'une table (15) pour maintenir la matière particulaire dans le récipient, comprend une unité d'alimentation (19) mobile sur la table et qui décharge les matières à travers une ouverture de sortie périphérique (18); ainsi que des moyens d'entraînement (20) de l'unité d'alimentation (19), qui est munie de surfaces d'alimentation (28, 30) s'étendant sur toute la périphérie de la table (15). Selon l'invention l'unité d'alimentation (19) comprend au moins deux éléments d'alimentation espacés (22, 23, 24) agencés de manière à pouvoir déplacer la matière depuis la partie centrale de la table vers l'ouverture de sortie. L'agencement des éléments d'alimentation est telle que, pendant un cycle complet de mouvement de l'unité d'alimentation, ils sont en alternance soit actifs dans une section arbitraire de la table (15) s'étendant entre la partie centrale et l'ouverture de sortie (18) pour décharger des couches de matière particulaire devant lesdits éléments dans le sens de l'ouverture de sortie, soit inactifs lorsqu'ils reprennent leur position de départ.
