Abstract:
1. A system for packing bulk material in a container, which system comprises: a transfer base including proximate and distal ends and a container packer guide, said transfer base including a floor, and said container packer guide comprising said transfer base floor; a container packer including a proximate end, a distal end with an opening, opposite sidewalls, a floor, an interior, and rollers mounted on said container packer floor adapted for rolling over said transfer base floor; said container packer being movable longitudinally along said container packer guide between a retracted position on said transfer base and an extended position extending at least partially from said transfer base distal end; said container packer having a pair of door tracks each extending along a respective side of said door opening and along a respective container packer sidewall; a door being movably mounted on said tracks; a pair of container packer door piston-and-cylinder units each connected to a respective container packer sidewall and to said container packer door; said container packer door piston-and-cylinder units operably moving said door between its open and closed positions; a container packer drive connected to said transfer base and said container packer and adapted for moving said container packer between its extended and retracted positions; a material transfer assembly mounted in said container packer interior and adapted for discharging bulk material through said container packer distal end opening; a material transfer assembly drive connected to said material transfer assembly and adapted for operating said material transfer assembly; said material transfer assembly comprising a push blade assembly located in and affixed to said container packer and movable longitudinally between a retracted position in proximity to said container packer proximate end and an extended position in proximity to said container packer distal end; said push blade assembly including a push blade extending transversely across said container packer interior, and adapted for compressing bulk material in said transport container; said container packer drive comprising a container packer piston-and-cylinder unit connected to said transfer base proximate end and said container packer proximate end; an hydraulic power source mounted on said transfer base and connected to said container packer piston-and-cylinder unit; said material transfer assembly drive comprising a push blade assembly piston-and-cylinder unit connected to said hydraulic power source and adapted for extending and retracting said push blade assembly between an extended position distally beyond said transfer base distal end and a retracted position adjacent to said container packer proximate end within said container packer interior, said push blade assembly movement sequentially cooperating with said container packer movement whereby said push blade assembly is adapted for compacting bulk material in said container; wherein said container packer drive piston-and-cylinder unit is attached at a position relative to the base of said container packer, and said push blade assembly piston-and-cylinder unit is attached at the approximate center of said push blade assembly; said material transfer assembly, including said material transfer assembly drive and push blade assembly, being adapted for sequentially filling said transport container with multiple container packer loads against said transport container distal end; a transport container selectively locatable in proximity to said transfer base distal end and adapted for selectively receiving at least a portion of said container packer with said container packer in its extended position; wherein said push blade is of substantially equal height and width as the internal dimensions of the container packer so that as the material transfer assembly can move and compact the entire volume of bulk material within said container packer assembly with one extension of said assembly piston-and-cylinder; and said push blade assembly further including a generally vertical blade mounted on said framework and extending generally transversely across said container packer interior.
