Abstract
An agricultural vehicle includes a threshing system that is configured to output straw material in a straw feed stream at a first location of the vehicle; a cleaning system that is configured to output a chaff feed stream at a second location of the vehicle that is different from the first location; and a residue handling system. The residue handling system includes (i) a chaff receptacle positioned and configured to receive weed seeds from both the straw feed stream and the chaff feed stream, and (ii) a weed seed mill that is configured to receive the weeds seeds from the chaff receptacle and devitalize those weeds seeds.
Claims21
An agricultural vehicle comprising:
- a threshing system that is configured to output a straw feed stream containing straw material into a strawhood of the vehicle;
- a cleaning system that is configured to output a chaff feed stream, which is separate from the straw feed stream, into the strawhood;
- and
- a residue handling system including (i) a chaff receptacle positioned and configured to receive weed seeds from both the straw feed stream and the chaff feed stream, and (ii) a weed seed mill that is configured to receive the weeds seeds from the chaff receptacle and devitalize those weeds seeds.
A residue handling system configured to process weed seeds contained in a straw feed stream and a separate chaff feed stream produced by an agricultural vehicle, said residue handling system comprising:
- a rotatable drum;
- a chaff receptacle having a perforated surface including openings sized to permit the passage of weed seeds and chaff therethrough, the chaff receptacle being positioned adjacent the rotatable drum, wherein the rotatable drum is positioned to thresh the straw and chaff feed streams against the perforated surface in order to separate the weed seeds from the straw and chaff feed streams;
- and
- a weed seed mill that is configured to receive the weeds seeds from the chaff receptacle and devitalize those weeds seeds.
