Определение рациональной интенсивности колебаний рабочих органов вибросепаратора зерновых смесей

Abstract

Рассмотрено движение частиц зерновой смеси по поверхности малогабаритной деки вибросепаратора, которая выполнена в виде цилиндрического желоба и оснащена отражателем в нижней его части. Показано, что рациональные режимы движения частиц (основной культуры и примесей) можно получить за счет надлежащего выбора интенсивности колебаний деки.

Розглянуто рух частинок зернової суміші по поверхні малогабаритної деки вібросепаратора, яка виконана у вигляді циліндричного жолоба і обладнана відбивачем в нижній його частині. Показано, що раціональні режими руху частинок (основної культури та домішок) можна одержати за рахунок належного вибору інтенсивності коливань деки.

The process of division of corn mixtures is explored on small workings organs as a cylindrical chamfer, equipped a reflecting plate in his lower part. A widespread case is considered, when the seed of basic culture have the rounded form, and including of litters - flat. Including of litters can be stems of plants, dead insects, lumps of soil, halves of seed. Seed of basic culture can be approximated a sphere. The feature of flat particles is that their motion suffices exactly described a financial point. Technologically expedient is the periodic mode of motion of particles, at which the period of their motion coincides with the period of vibrations of working surface. It is therefore necessary rational to count such intensity of vibrations, at which the periodic mode of motion of particles is most steady. On the base of differential equalizations of motion of particles the programs of determination of rational intensity of vibrations of working organ are created for a basic culture and including of litters. Intensity of vibrations was estimated the coefficient of the kinematics mode. It is set by the indicated programs, that at the use of rational intensity of vibrations for the seed of basic culture the periodic mode of motion of including of litters on a working surface is impossible. It is shown that acceptable combination of the modes of motion of particles of corn mixture is observed technologically, if the coefficient of the kinematics mode is adopted by a value near to unit.
