Abstract

A bulk material unloading apparatus comprises a vertical conveyor (10) and a horizontal conveyor connected thereto. A rotable feeder (13) is mounted at the feeding end of the vertical conveyor for feeding material thereinto. According to the invention, the apparatus also has a separately operable material supply device (23, 32) for the controlled supply of material to the feeder. The material supply device has a gimbal-mounted material draw-in device (32) which is universally tiltable relative to the axis of rotation of the feeder (13) and which preferably also is telescopically mounted in relation to the feeder.
