Molodyk M. Substantiation of Constructive-Technological Parameters of the Heap Pneumoseparation System in Combine-Harvesters of Black Currant

The object is technological process and means of pneumoseparation thrashed heap in combines for harvest a black currant; the purpose - increase of quality of system of pneumoseparation in combines for harvest a black currant; methods - mathematical modeling, theory of probabilities and mathematical statistics, high-speed filming, planning multifactoral of experiment, gas and hydraulic similarity; the novelty - is proved three stages technology of separation thrashed heap; the mathematical dependences of allocation of impurity and losses of berries are determined at separation from speed of an air flow in the chamber of separation, speed of introduction thrashed heap in a zone of separation, corner of an inclination of an air flow and other parameters; results - the opportunity of preliminary pneumoseparation is determined; the structure and percentage of each fraction thrashed heap, after removal by his activator is determined; the correlation dependences between the size and mass characteristics and hovering velocity of fractions thrashed heap are received; The mathematical model of process of preliminary preparation вороха, stratification it with the help of vibration is received; the results of work are introduced at modernization and development of a new combine; branch - farm machine building.
