Aggregating of component modules of the KZR-10 (КЗР-10) grain-harvesting machine with multipurpose power vehicle

In agriculture of European countries new grain-harvesting machines of higher technical level, namely module-construction aggregates based on multipurpose power vehicles and replaceable harvesting modules are designed and used. These aggregates have some disadvantages and need to be improved. The object of the research is to determine the direction of improving of methods for aggregating of component modules of series-manufactured grain-harvesting machine KZR-10 (КЗР-10) with its chassis. It is supposed that the aggregating of such modules with the chassis is reasonable in the case of supplying of harvested product to thrashing and separating device of the machine, and its further cleaning in grain cart. It is possible when improving the layout diagram of chassis of multipurpose power vehicle and aggregating of component modules with it. In proposed variant of aggregating, the chassis of multipurpose power vehicle has running wheels with equal diameter and undermount power unit between them. The driving cab is adapted to quickly moving on the chassis in traversal and vertical directions. Main module of machine, the thrashing and separating device is mounted on the top of chassis by means of proper mechanism. The rotor of thrashing and separating device is located along longitudinal axis of chassis and combines thrashing and longitudinal direct-flow travel of thrashed heap, and its transfer to grain cart. The header of harvesting module is mounted on the chassis of multipurpose power vehicle by means of the feed elevator matching with thrashing and separating device. The indices of aggregating of component modules of grain-harvesting machine with chassis of multipurpose power vehicle are determined by calculations. They confirm that new aggregating scheme is appropriate. Such aggregating allows to reduce the load coefficient of carrying wheels of chassis of multipurpose power vehicle and to increase the load coefficient of driven wheels and controllability of chassis according to Russia's existing safety standard.
