Concave assembly and support structure for a rotary combine
First Claim
1. A rotary combine comprising:
- a rotor having a longitudinal axis of rotation;
a support structure disposed adjacent said rotor;
a longitudinally extending frame having first and second sides spaced circumferentially around said rotor, each of said first and second sides moveably mounted to said support structure, wherein each of said first and second sides is transversely moveable relative to said longitudinal axis of rotation; and
a concave insert removably mounted to said frame, said concave insert outwardly removable from said frame in a direction transverse to said longitudinal axis of said rotor.

Abstract
A rotary combine includes a rotor having a longitudinal axis of rotation and a concave removably mounted adjacent the rotor. The concave is removable in a direction outwardly transverse relative to the axis of rotation of the rotor. In a preferred embodiment, a concave assembly includes a longitudinally extending frame having first and second sides spaced circumferentially around the rotor. Each of the first and second sides is transversely moveable relative to the axis of rotation of the rotor. A concave insert is removably mounted to the frame. A method for adjusting the position of the concave assembly is also provided and includes moving at least one of the first and second sides of the frame in a direction transverse to the axis of rotation. A method for replacing the concave insert is also provided.

23. A rotary combine comprising:
-
a rotor having a longitudinal axis of rotation;
a longitudinally extending frame comprising first and second sides spaced circumferentially around said rotor and at least a first and second rib member extending transversely between said first and second sides of said frame, said first and second rib members longitudinally spaced and defining an opening therebetween; and
at least a first and second concave insert, each of said first and second concave inserts comprising a first and second end spaced circumferentially around said rotor, said first end of said first concave insert removably mounted to said first side of said frame and said first end of said second concave insert removably mounted to said second side of said frame, each of said first and second concave inserts dimensioned to be removed from said first and second sides of said frame respectively in a transverse direction through said opening and away from said rotor. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
