Parameters and indicators of the longitudinal-transverse oscillation sieve
Аннотация
Abstract The work quality of the grain cleaning machines depends on work indicators of the sieve. Based on this, longitudinal-transverse oscillation sieve developed for grain cleaning machine. The developed sieve researched theoretically and experimentally. According to the researches, it was defined that the longitudinal oscillation of the grain-cleaning sieve n fr = 140 – 175 rpm, the amplitude of the longitudinal oscillations A l = 30 mm, the amplitude of the transverse oscillations A t = 3 – 5 mm, and the slope angle α s =14°. In these operating parameters work indicators of the sieve consisted of the grain losses is not more than 0.5 % and cleaning efficiency is 99.6 %. It found that the quality indicators of the longitudinal-transverse oscillation sieve on the same loads are 1.2 – 2.3 times higher than the longitudinal oscillation sieve.
