Abstract
A threshing and separating system including a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open end portion to a second open end portion. The first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point. The threshing and separating system also includes a rotor configured to rotate within the non-stationary rotor cage to thresh harvested crop. The non-stationary rotor cage is configured to rotate about an axis extending between the first rotatable coupling point and the second rotatable coupling point, and to be rotationally driven by the rotor via the threshed harvested crop.
Claims20
A threshing and separating system comprising:
- a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open end portion to a second open end portion, the first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point;
- and
- a rotor driven by a motor to rotate in a rotational direction within the non-stationary rotor cage to thresh harvested crop,
- wherein the non-stationary rotor cage is driven by friction between threshed harvested crop and the rotor cage to rotate in the rotational direction about an axis extending between the first rotatable coupling point and the second rotatable coupling point.
A combine including:
- a feeder housing for receiving harvested crop;
- a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open that receives the harvested crop end portion to a second open end portion that expels the harvested crop, the first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point;
- and
- a rotor driven by a motor to rotate in a rotational direction within the non-stationary rotor cage to thresh the harvested crop,
- wherein the non-stationary rotor cage is driven by friction between threshed harvested crop and the rotor cage to rotate in the rotational direction about an axis extending between the first rotatable coupling point and the second rotatable coupling point.
