  • Machine for loading silage bag
    Patent number: 7261129
    Abstract: A machine for compactly loading an elongate polymer storage bag includes a chamber through which one or more rams reciprocate in a generally horizontal direction, forcing bulk material such as compost, distillers grains, silage, or feedstuffs from the chamber into a frame that carries the gathered sidewall of the storage bag. The frame has a curved upper surface and an open bottom. The bag filling machine is supported on wheels and is forced gradually forward as the bag fills, against the restraint of an adjustable brake. A loading elevator mounted to the side of the bag loading machine feeds the bulk material into the chamber.
