  • Patent number: 5014845
    Abstract: A trough for a livestock feed conveyor, the conveyor having conveying devices such as paddles residing in the trough and a drive unit for moving the conveying devices within the trough so as to convey the feed. In a preferred embodiment, the trough is constructed of an upper trough portion, a lower trough portion attached to the upper trough portion, each trough portion including segments, with transverse boundaries between the segments, connecting plates for connecting the segments of each of the trough portions together, the relative lengths of the segments of both trough portions being chosen and assembled so that the boundaries between segments of the upper trough portion do not coincide with the boundaries between sections of the lower trough portion.

  • Patent number: 4775047
    Abstract: Articulated decline belt conveyor in which the elbow is defined by a pair of rollers respectively attached to the joined sections of the frame for dividing the decline angle into two smaller parts. The belt is transversely troughed over much of its length, but is flattened by the pair of rollers defining the elbow, thereby permitting a more substantial decline angle than if the belt was transversely troughed while traversing the elbow. Improved structures for supporting the conveyor frame are also disclosed.

  • Patent number: 4593651
    Abstract: Disclosed is a feed conveyor for receiving feed and depositing it into a feeder bunk. It includes a hopper for receiving feed and depositing it upon a motor-run belt conveyor. Disposed between the upper or load-carrying flight and the lower or return flight of the conveyor belt are pulleys over which is reeved a cable, rope or chain in a horizontal plane, that is, each cable flight is located laterally with respect to the opposite flight. These pulleys are run by a drive taken from the same motor as that driving the belt of the conveyor via pulleys which transfer the plane of the drive belt from the vertical to the horizontal. The cable joined into a continuous loop by a cable clamp having holes drilled in one face thereof for insertion of the cable ends and a concave semi-cylindrical depression formed in the same face so as to match closely the radius of the pulleys driving the cable.
