International ClassA01F 012/44AbstractA harvesting method gathers and threshes grain in the field, leaving behind the straw. It removes chaff and weed seeds from the field with the harvested grain, and separates the chaff, grain leavings and weed seeds from the grain in a separate yard plant. The chaff, grain leavings and weed seeds are compacted and crushed in a mill for use as animal feed. The simplified harvest units have augmented holding tanks, one version of which can be attached to (and detached from) existing farm tractors. An automated integrated yard plant (1) separates and cleans harvested grain and (2) compacts and crushes chaff, grain leavings and weed seeds for use as animal feed.Field of SearchCLEANERWITH HOPPER Centrifugal Transverse threshing section THRESHING SEPARATOR Straw walker STRAW CHAFF SPREADER OR HANDLING (DISCHARGE) With chopper DRIER MACHINE COMPONENT ARRANGEMENT AND STRUCTURE, E.G., ENGINE PLACEMENT, GRAIN BIN PROCESS MISCELLANEOUS GRAIN SAVER With thresher or crop-separator unit Cutter unit and conveyer unit CUTTING AND CATCHING CUTTING, CONVEYING AND THRESHING Gauging passage between stationary element (e.g., bar, slat, etc.) and orbiting belt Items move longitudinally of elongate elements With means moving, or regulating movement of, items along elements | |
