发明名称 Hog feeding device of improved durability
摘要 A hog feeding device is provided comprised of a hopper assembly and underlying multi-compartment base unit. The parts of the device which are ordinarily subject to rapid deterioration, namely the base unit and the end walls of the hopper assembly, are fabricated from concrete as monolithic components. Because of special features of construction, the monolithic components can be easily fabricated, and the device can be readily assembled from its component parts.
