Theoretical analysis of the interaction forces of weeds and volatiles upon impact on the grate

In recent years, a trend has emerged based on the method of imparting mobility (degree of freedom) to the grate. The practical implementation of this method is carried out in two ways: a grate where the grates receive movement under the influence of a technological load, and in the second when the grate is forced. The work theoretically and experimentally investigated the impact interaction of raw cotton with grates. Typically, in grate-serk type cleaners, raw cotton is cleaned by striking clogged flywheels mounted on a serrated set against stationary grates. The article examines the process of impact interaction of a clogged fly with a grate having forced rotation. Formulas have been proposed for determining shock pulses acting on fly and impurities when hitting a grate with forced rotation. This will allow us to find ways to increase the cleaning effect of using a grate with forced rotation in a cotton ginning unit. Formulas have been obtained for determining the shock impulses acting on fly and impurities when hitting a grate with forced rotation. The values of impact forces are determined, calculated depending on the diameter and rotation speed. The cleaning effect of using a grate with forced rotation in a cotton ginning unit is 95.5-97.5 %.
