The results of the experimental nature of the vibrations of the grid cotton cleaner

Abstract

Abstract The article provides a new effective scheme and principle of operation of a multifaceted grid of cotton cleaner from small trash. The results of comparative experimental studies of the grid oscillations and the nature of loading depending on the parameters and modes of cotton cleaning are presented. In the experiments performed, the nature of the vibrations was investigated by studying the component vibrations of two grids simultaneously to compare the results. An analysis of the obtained laws of grid vibrations showed that the amplitude of the recommended multifaceted mesh surface on the elastic supports exceeds the amplitude of vibrations of the existing grid 5–7 times and reaches up to (2 ÷ 2.5) × 10−3 m. In this case, the oscillograms are presented for steady-state modes of the work of the cotton cleaner. The results show that an increase in the coefficient of the number of faces of the grid leads to a decrease in the load of the grid to (0.3 ÷ 0.5) N. The parameters of a multifaceted grid of cotton cleaner from small trash are substantiated. Experimental studies have studied the workload and the law of vibrational motion of the grid surface.
