The invention relates to a device for discharging material from a silo (10), comprising a long discharge channel (22) extending centrally over the silo floor (14), and a push-frame (20) which can be pushed back and forth hydraulically over the silo floor (14), over the discharge channel (22), crossways to the longitudinal extension of said discharge channel (22). According to the invention, the push-frame (20) is driven by means of two radially arranged hydraulic cylinders (40) which face each other diametrically inside the silo (10). The hydraulic cylinders (40) can be activated with a push-pull control mechanism, and are each situated in a cylinder housing, said cylinder housings being connected to the silo floor (14). The piston rods (46) of the hydraulic cylinders are arranged so that their opposite front faces (44) fit against a driver bearing (48) from opposite sides, said driver bearing (48) being located in the centre of the push-frame (20).
L'invention concerne un dispositif permettant d'extraire des matériaux d'un silo (10), qui comporte une rigole de décharge (22) qui s'étend le long du fond du silo (14) et un cadre coulissant (20) pouvant être déplacé hydrauliquement en va-et-vient transversalement à son étendue en longueur sur le fond du silo (14) au-dessus de la rigole de décharge (22). Selon l'invention, l'entraînement du cadre coulissant (20) est assuré par deux vérins hydrauliques (40) diamétralement opposés, dirigés dans le sens radial, pouvant être actionnés en push-pull. Chacun des vérins hydrauliques est monté dans un boîtier de cylindre solidarisé avec le fond du silo (14). Les faces d'about (44) des tiges des vérins (46) appuient depuis des côtés opposés contre un palier d'entraînement (48) monté de manière centrée sur le cadre coulissant (20).
