To the question of justification of optimal parameters of the screw divider of the header portion

The relevance of the portion harvester for harvesting grain crops split method is substantiated; its main structural features and considers the essence of the technological process are described. The article deals with the essence of the process of preventing contact of beveled grain stalks with wheels of the mobile energy means during the operation of the header, as well as the design and technology of the devices used for this purpose. The research on the establishment of the optimal parameters of the screw divider of the portion header, which is the main component of the device for the removal of bread mass, is presented. The established optimal design and operating parameters of the screw divider, which provides the correct operation of the device for the removal of bread mass from the wheels of the mobile device, are presented.
