ABSTRACT:
A conveyor system for slip-form concrete and similar paving materials includes a V-shaped hopper having a material supporting beam extending longitudinally through it, and a conveyor for unloading paving materials from the hopper. The vertical positioning of the material supporting beam in the hopper is adjustable to control the amount of material that is unloaded during each increment of conveyor travel. The hopper includes channels which both protect and provide access to the components of the conveyor and the material supporting beam is supported solely at its ends, so that the system may be thoroughly cleaned after each use.
