Abstract:

The article outlines the operating concept of the recommended multifaceted gridirons on an elastic bearing support, analyses the excursion of the gridiron, justifies the characteristics and gives the results of comparative production tests. As well as the effective scheme and principle of work of cotton cleaner from large impurities are presented based on the research of fluctuations in the parameters of a grid-iron on an elastic support system. The obtained results of the recommended cotton cleaner were provided. Experiment results showed that the cleaning purificatory effect increases on average by up to 8.11% in comparison with the existing option of a fire grate; mechanical damage to seeds decreases by up to 1.09%, and free fibre in the seed-cotton decreases two times, to 0.113%. With an increase in the resistance of cotton from 19.7 Н up to 60 Н (average value), the movement of the gridiron increases from 0.65·10-3 m up to 3.2·10-3 m. This is due to the fact that in the interaction of raw cotton with vibroisolating conical grates, cotton-yarn is additionally shaken, increasing their direction of movement due to the taper rate of the gridirons, which leads to an increase in the cleaning effect.
