International ClassA01D 041/06AbstractA 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 SearchWith thresher or crop-separator unitCutter unit and conveyer unit CUTTING AND CATCHING CUTTING, CONVEYING AND THRESHING WITH HOPPER Centrifugal Transverse threshing section THRESHING SEPARATOR CLEANER 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 | |
