Annotatsiya

A GeoGebra-based geometric model was used to compare spindle and pressing-sector motion in ellipticaland circular drums of a vertical-spindle cotton picker. With 12 spindles, a 14.6 cm semi-minor axis, a 1.45 cm spindleradius, a 3.2 cm pressing-sector radius, and a 150° wrap angle, varying the semi-major axis and sector position generateda quasi-elliptical sector-edge path and zigzag entrance zones, whereas the circular configuration produced concentricpaths. The results indicate potential for improved plant guidance; harvesting performance requires experimentalvalidation.
