FIELD: agriculture.
SUBSTANCE: group of inventions relates to rotors and housings for axial-rotor agricultural harvesters. Threshing and separating mechanism for the harvester has a support structure. It comprises an elongated rotor mounted in the support structure and having the threshing or separating parts. The elongated housing is installed in the support structure with the ability to rotate about the axis of the rotor and has sections similar to the rotor. The housing covers the rotor and is separated from it with a gap to move the grain material flow in the direction from the housing inlet end to the housing outlet end. The housing has an upper part above the rotor, which determines the distance between the parts of the sections and the axis of the rotor. Between the sections of threshing and separation there is a transition section. The harvester with axial centrifugal thresher is designed for collection, threshing and separation of the grain material and comprises a support structure. The elements projecting from the support structure are in contact with the ground surface for movement of the support structure along the field. The rotor housing has a threshing section and a separation section. The rotor is equipped with elements that come into contact with the grain material passing through the rotor housing. The transition section has a form of a truncated cone, and connects the threshing section with the separation section.
EFFECT: efficient energy consumption is ensured, the service life is increased, and damage to the harvested grain is reduced.
