Embodiment Construction

[0022] For convenience, the terms "grain", "stalk" and "tails" are primarily used in this specification, but it should be understood that these terms are not intended to be limiting. Thus, "cereal" refers to the portion of crop material that is threshed and separated from the discardable parts of the crop material, known as non-cereal crop material, MOG or straw. Incompletely threshed crop material is referred to as "tailing". Likewise, the terms "front", "rear", "left" and "right" when used in connection with an agricultural harvester and / or components thereof are generally identified with reference to the forward operating direction of travel of the harvester, but again, they should not be used interpreted as restrictive. The terms "longitudinal" and "transverse" are defined with reference to the fore-aft orientation of the agricultural harvester and as such should not be construed as limiting. The terms "downstream" and "upstream" are determined with reference to the expe...

Abstract

A threshing and separating system for an agricultural harvester includes a rotor configured to rotate about a rotor axis, a rotor cage at least partially enclosing the rotor and including a tailings return inlet formed therein and configured to couple to a tailings return elevator and an insert opening formed therein that is at least partially circumferentially aligned with the tailings return inlet relative to the rotor axis, at least one concave coupled to the rotor cage and defining a plurality of concave perforations, and a threshing insert removably coupled to the rotor cage and includingat least one mounting opening. The threshing insert at least partially covers the insert opening and is positioned such that material from the tailings return inlet travels past the threshing insertbefore reaching the concave.

Description

technical field [0001] The present invention relates to an agricultural harvester, more particularly, to a rotor cage of the agricultural harvester. Background technique [0002] An agricultural harvester known as a "combine" was historically so called because it would combine multiple harvesting functions, such as picking, threshing, separating and cleaning, with a single harvesting unit. A combine harvester includes a header that removes crop from the field and a feeder housing that transports crop material into the threshing rotor. The threshing rotor rotates within a perforated housing, which may be in the form of an adjustable recess, and performs a threshing operation on the crop to remove grain. Once the grain is threshed, it falls through the perforations in the recess onto the grain pan. A cleaning system is used to remove grain from the grain pan, which is then conveyed to the grain tank on the combine harvester. A cleaning fan blows air through the sieve to dis...
