ABSTRACT:
A door frame for use in the discharge doors of silos which is adapted to be quickly moved from one frame to another as silage is removed from the silo, and which will support a hood or funnel used with clean chute systems for discharging silage from the silo. The door frame also may provide a support for the silo unloader, including guides for the normal gooseneck discharge conduit of the unloader and its torque restraining means. The frame provides a rack for receiving and storing the silo door which is removed for installation of the frame. The frame is adjustable to tightly fit into different size door openings. In a preferred embodiment the door frame is raised and lowered into position through the use of a winch and motor assembly, thus making the changing of the movable door frame that supports the hood for the clean chute assembly simple, and relatively labor free.
