摘要： A thresher for a combine harvester has a concave cage and a rotor disposed within the concave cage. The rotor carries material manipulators that extend outward from the rotor toward the cage to manipulate material in the concave cage as the rotor rotates. One or more air nozzles are provided that direct air outward from the rotor and toward the concave cage. A source of forced air circulates air through the one or more air nozzles.

摘要： A concave for a combine harvester includes a body consisting of a grid of straight longitudinal bars arranged in a concave configuration. Each of the longitudinal bars have a leading face, a trailing face, and an upper extremity. At least one of the longitudinal bars has a longitudinal cavity positioned along the leading face at the upper extremity. A wear resistant insert is positioned in the longitudinal cavity. The wear resistant insert is detachably secured to and receives underlying support from the said at least one of the longitudinal bars. The wear resistant insert provides a replaceable leading edge.

摘要： There is provided a concave for a rotary combine which includes a body having a plurality of curved frame sections connected in parallel side by side relation. Each of the curved frame section has having ends and sides. The body has an entry end and an exit end. Each of the curved frame sections has a face with an upstanding crop processing profile. For the curved frame sections at the entry end of the body the crop processing profile is a threshing profile having an orientation extending between the sides. For the curved frame sections at the exit end of the body the crop processing profile is a separation profile of sine wave vanes having an orientation extending toward the ends and having apertures positioned between the vanes to permit passage of grain.
