Analysis and Experiment of Dynamic Picking Process of Spindle of Cotton Picker

The spindle is a key core component of cotton picker, and its operating parameters directly affect the quality harvesting. In this study, was selected as research object. kinematics mechanics analysis cotton-picking process conducted, dynamic motion trajectory obtained, working affecting picking performance were determined. A test bench for built; speed feed used factors; seed rejection rate, time, force evaluation indices performance; full-factor conducted. range, variance, regression analyses conducted on results, results showed that had significant effects force, time (p < 0.01). primary secondary order factors rate speed, speed. By comprehensively analyzing influence indices, best combination obtained 4000 r/min 1.8 m/s, respectively. have theoretical value practical significance revealing law spindles when rotating at high then realizing efficient
