FIELD: agricultural engineering, in particular, tractor-hitched harvesting machines for combing of cereal crops and transportation of yield into vehicle.
SUBSTANCE: tractor-hitched harvesting machine has drive part, frame, combing device with combing drums, and transportation screw. Fan suction throat is connected to discharge window of transportation screw. Fan is made in the form of ejector with drive and rotational speed variator. Ejector has heap flow guide positioned adjacent to discharge window of transportation screw to define in conjunction with suction throat edge receiving chamber formed as concentric circle. Cereal crop spikes are combed by drums and directed by transportation screw to fan formed as ejector. Heap with free grain and non-grain part is delivered onto fan and directed by kinetic energy of its blades and air pressure through pneumatic conveyor into vehicle. Employment of kinetic energy of fan blades allows heap to be additionally threshed.
EFFECT: increased efficiency and enhanced reliability in operation.
