Abstract
An improved threshing and separating mechanism for a combine that includes an elongated rotor mounted for rotation about a rotor axis within a rotor housing on the combine. The rotor has a threshing portion and a separating portion. The housing has a threshing section and a separating section corresponding to the threshing portion and the separating portion. The housing surrounds the rotor and is spaced from the rotor to form an annular space between the rotor and the housing for crop material to flow through in an axial crop flow direction from an inlet end of the housing to an outlet end of the housing. A rear portion of the rotor tube includes one or more discharge flights or vanes that are adjustable in height and assist in discharging material through the outlet of the rotor housing. The discharge vanes work in conjunction with the vanes in the top covers of the rotor housing.
