  • Adjustable guide vanes for an axial flow rotary separator
    Patent number: 4258726
    Abstract: In an axial flow rotary separator for a combine harvester, a series of parallel guide vanes are mounted inside the upper portion of the separator housing. The guide vanes are each helically disposed and parallel to each other and they cooperate with the separator rotor so that as the rotor is rotated crop material which has been fed to an upstream end of the separator is propelled downstream as a mat in the annular space between rotor and housing, the guide vanes engaging the mat of material and deflecting it downstream as it is propelled circumferentially by the rotor so that any given portion of the mat is propelled downstream in an approximately helical path.
    Type: Grant
    Filed: July 5, 1979
    Date of Patent: March 31, 1981
    Assignee: Deere & Company
