Abstract
In this article, it is described that the synthesis of the mechanism of an elliptical drum of a vertically spindle drum, which increases the completeness of the collection and the quality of the harvested raw cotton. In particular, it developed a methodology for substantiating the profile and dimensions of the guide track, which ensures the movement of the spindles along an elliptical trajectory. At the same time, the profile and dimensions of the guide track are considered as a function of the trajectory and kinematic modes of the spindle. It is shown that the trajectory of movement and kinematic modes of the center of the guide roller can be the basis for choosing the profile and basic geometric dimensions of the guide track. The trajectory of the center of the guide roller at its different positions relative to the center of the spindle, moving along an elliptical trajectory, is determined using the Geo Gebra program, which is popular in the mathematical modeling environment, and its kinematic parameters are determined by constructing hodographs of the speed of the center of the guide roller.
