Abstract
Device for discharging material from a silo (,), comprising a long discharge channel (,) extending centrally over the silo floor (,), and a push-frame (,) which can be pushed back and forth hydraulically over the silo floor (,), over the discharge channel (,), crossways to the longitudinal extension of said discharge channel (,). According to the invention, the push-frame (,) is driven by means of two radially arranged hydraulic cylinders (,) which face each other diametrically inside the silo (,). The hydraulic cylinders can be activated with a push-pull control mechanism, and are each situated in a cylinder housing, said cylinder housing being connected to the silo floor (,). The piston rods (,) of the hydraulic cylinders are arranged so that their opposite front faces (,) fit against a driver bearing (,) from opposite sides, said driver bearing (,) being located in the center of the push-frame (,).
