DEVICE FOR THRESH OF GRAIN CULTURES

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agricultural mechanical engineering and can be used in the threshing mechanisms of combine harvesters and stationary threshers. The threshing mechanism comprises an air and jet generator of ultrasonic oscillations, a parabolic reflector and a conveyor. The generator is linked with the reflector. The conveyor is located under the generator. The air and jet generator of ultrasonic oscillations creates oscillations in the air medium. The parabolic reflector directs oscillations from the generator to spiked mass. The conveyor supplies spiked mass to a radiation zone.;EFFECT: decrease of damage and crushing of grain is provided, straw crushing is excluded.;4 cl, 1 dwg
