EXPERIMENTAL STUDIES OF GRATE PROFILE VARIANTS ON THE COARSE DEBRIS MODULE EXPERIMENTAL PLANT

Abstract

The article deals with development of new grid profi les in the equipment for cleaning of seed cotton from major impurities, improvement of the cleaning effi ciency of the machine, and calculation processes. Four types of grid profi les were considered for cleaning machines when cleaning seed cotton from small and large impurities. Two versions of the profi les were installed: a radius-shaped and a curved metal grill. Profi le fences were developed at the "Pakhta Djin KB" practical plant and joint research was conducted on installing of an experimental full-profi le bench. Experiments were carried out at diff erent speeds to determine the performance and cleaning effi ciency by studying diff erent profi les of the column bars in the experimental equipment for cleaning cotton from large impurities. The results of the experiment showed that the iron sheet bent colosnik grid is preferable. The recommended iron columnar grating is recommended for industrial implementation.
