Fully Tapered Rotor Nose and Threshing Section
First Claim
1. A threshing mechanism for a combine having a supporting structure, the mechanism comprising:
- an elongated rotor for moving crop materials;
an elongated housing for surrounding said elongated rotor and for defining a volume of space between said rotor and said housing;
said housing and said rotor mounted in said supporting structure;
said rotor having a rotor tube with a conical profile substantially throughout a threshing section of said rotor; and
a plurality of threshing elements mounted on a surface of said rotor tube in the threshing section.

Abstract
A threshing and separating mechanism for a combine includes an elongated rotor mounted for rotation about a rotor axis on the combine within a rotor housing. The rotor has a threshing portion and a separating portion. The rotor has a rotor tube that is tapered continuously in the threshing portion and has threshing elements extending from the rotor tube. 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 tube to form an annular space between the rotor tube 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. The housing includes a smooth transition section between the threshing section and the separating section of the housing.
