DEVELOPMENT AND CALCULATION OF A MATHEMATICAL MODEL OF THE PATH OF MOTION OF POINTS ON THE SPINDLE IN THE ZONE OF COTTON REMOVING OF THE HARVESTING MACHINE

Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 2

Abstract

The process of removing cotton from the spindle as it moves in the removal area of the harvesting apparatus is examined in the article. The doffers, which are one of the components of the harvesting apparatus, perform a complete removal of cotton from the spindles, clean the surface of the spindle from individual fibers and cotton leaves, and ensure a continuous supply of raw cotton removed from the spindles into the receiving chamber for its further transportation to the hopper of the cotton harvester. A computational scheme for the spindle motion in the removal zone was developed and, on its basis, the path of the points lying at the ends of the doffer brushes, and the shapes of the curves enveloping these paths, were determined. These curves can be considered the boundaries of the zone of direct interaction of the doffer with a skein of cotton on the spindle. Based on modeling the process of interaction of the cotton-carrying spindle with the doffer in the removal zone of the harvesting apparatus, a calculation formula was obtained to determine the boundary of the zone of effect of the doffer brushes on a skein of cotton wound on the spindle; numerical calculations were conducted in the MathCAD 15 programming environment. The calculation results showed that with an increase in the angular velocity of spindle rotation, the boundary of the zone of effect of the doffer brushes is significantly closer to the spindle circle, which leads to a complete removal of cotton.
