THRESHING DEVICE FOR HARVESTER, HARVESTER AND METHOD OF MOVEMENT OF AGRICULTURAL CROP THROUGH THRESHING DEVICE Russian patent published in 2013 - IPC A01D41/00 A01F12/18 

FIELD: agriculture.

SUBSTANCE: invention relates to rotors and housings for axial rotor agricultural harvesters. The threshing device for a harvester has a support structure comprising an elongated rotor for movement of agricultural crop material, an elongated housing for surrounding the elongated rotor and for formation of the space between the rotor and the housing. The housing comprises an outlet. The housing and the rotor are mounted on the support structure. On the first part of the rotor outlet end of the outlet blades are mounted. The outlet blades extend from the first part surface. The said blades are configured with the ability to adjust in height, at which the blades extend from the surface. The harvester is equipped with a rotary threshing device comprising a housing surrounding the rotor to form the space between the rotor and the housing and passage of the agricultural crop material towards the outlet end of the housing. In implementation of the method of movement of the agricultural crop material through the threshing device of the harvester a rotor is provided which comprises the outlet blades attached to the outlet end of the rotor. Then the height is adjusted at which the outlet blades pass from the outlet end of the rotor. Then the elongated housing is provided, surrounding the rotor to form the space for the agricultural crop material. The agricultural crop material is fed into the inlet of the housing. The agricultural crop material is moved by rotation in the direction of the outlet of the housing. The interaction of the agricultural crop material with one or more outlet blades mounted on the rotor is provided for removal of agricultural crop materials from the housing.

EFFECT: increased efficiency of straw material discharge, increased durability and reduced damage to the straw.
