SUBSTANTIATION OF THE UNLOADING TRANSPORTER DELIVERY TO LOAD GRAIN DRILLS
The purpose of the study was to substantiate the delivery of an unloading conveyor to load grain drills, depending on the design parameters of the seed drill in order to ensure stable operability of the machine operator during the working shift. Since the performance of the unit and the quality of the work depend on the psycho-emotional state of the operator, it was possible to maintain the stable operability of the machine operator during the shift and high quality of his work, allowing technological stops, during which the operator did not participate in the management of the implement. The time components needed for performing the technological operation, the frequency and duration of time for technological stops of the grain drill and the time of its movement until the next refueling have been determined. The dependencies described made it possible to determine the required supply of an unloading conveyor for any seeder, which was maintaining stable working capacity during the shift time. It was proved that the maximum delivery rate of the discharge conveyor for grain drills loading was 39.96 t/h for mechanical seeders with the working speed of 15 km/h. The minimum delivery rate was 19.0 t/h for a seeder with the working width of 3.6 m and a working speed of 12 km/h
