Abstract
A material conveyor system comprises a substantially upright mechanically or pneumatically operated conveyor and a device for loosening material and for feeding the same into the upright conveyor. The device comprises a substantially horizontally extending tubular jib adjustably connected to an upright support frame supporting the upright conveyor. The tubular jib rotatably supports on its outer periphery a material loosening and transporting device comprising a plurality of axially extending circumferentially displaced shovels which feed the loosened material through at least one elongated inlet opening into the interior of the tubular jib through which a conveyor extends which feeds the material in longitudinal direction of the jib into the upright conveyor. If the upright conveyor is pneumatically operated, the conveyor extending axially to the jib is preferably a screw conveyor and when the upright conveyor is mechanically operated, the conveyor through the jib is a band conveyor extending also through and forming part of the upright conveyor.
