Abstract
A straw chopper for a combine harvester including a rotor supporting a plurality of chopping elements. A rotor housing including an inlet opening, an outlet axially aligned with the inlet opening, and at least one outlet that is axially offset from the inlet opening. A portion of the straw is conveyed tangentially to the axially-aligned outlet, whilst a further portion is conveyed from the inlet opening to the axially offset outlet(s) via a path having an axial component, for example a helical path. Guide vanes may be provided on the inside of the housing to impart an axial force upon the straw.
Claims15
An apparatus for chopping and discharging crop residue, the apparatus comprising:
- a rotor comprising a plurality of chopping elements, the rotor rotatable about an axis;
- and
- a rotor housing comprising a tube structure, a first end wall at one end of the tube structure and a second end wall at an opposite end of the tube structure, the rotor housing further comprising:
- an inlet opening formed in the tube structure;
- a first outlet formed in the tube structure of the rotor housing having a first discharge spout through which a first portion of the crop residue is discharged from the rotor housing, wherein the first outlet is axially aligned along the axis with the inlet opening;
- and
- a second outlet formed in the tube structure of the rotor housing having a second discharge spout through which a second portion of the crop residue is discharged from the rotor housing, wherein the second outlet is axially offset along the axis from the inlet opening such that the second outlet and second discharge spout are separated from the first outlet and first discharge spout by a portion of the tube structure of the rotor housing.
