  • Rotary combine having a concentric infeed section and eccentric threshing and separating sections
    Patent number: 5688170
    Abstract: An axial agricultural combine having a single element rotor defining a rotor axis. The rotor is housed in a rotor housing having an infeed section, a threshing section and a separating section. The infeed section of the rotor housing defines a infeed axis, the threshing section of the rotor housing defines a threshing axis and the separating section of the rotor housing defines a separating axis. The infeed axis is parallel to and in line with the rotor axis. The threshing axis is parallel to and offset from the rotor axis. The threshing axis is offset above and downstream from the rotor axis. The separating axis is parallel to and offset from the rotor axis. The separating axis is offset above and downstream from the rotor axis. The separating axis is more offset from the rotor axis than the threshing axis is offset from the rotor axis.
