Miss-picking Mechanism Analysis and Experiment of Peanut Windrow with Spiral-finger Cylinder Peanut Pickup Device
摘要
Abstract
[Objective]To address the issues of pod loss caused by miss-picking of peanut plants and unreasonable working parameters of the pickup device without a slide track,a spiral-tooth rotary pickup device was proposed.The analysis of the mechanism of miss-picking and picking up experiment were conducted.[Methods]Based on the biological characteristics of peanut plants during the maturity stage,the pickup characteristics of peanut windrows in China and the United States were compared.The formation mechanism of missed pickup areas in peanut windrows was thoroughly investigated,and experimental studies were carried out on the spiral-tooth rotary pickup device.Using the motion trajectory of the spring tine tips,the pickup area and missed pickup area during the picking process were analyzed,and a mathematical model of the missed pickup area was established.The relevant structural and operational parameters affecting the missed pickup area were identified,based on which the experimental factors for the pickup tests were determined.Mathematical models of the trajectory,velocity,and acceleration of the spring tine tips were established.Kinematic and dynamic simulations of the pickup mechanism were conducted using Adams software,and a reasonable ratio of working parameters was determined.[Result]Through response surface experimental design and result analysis,the optimal working parameters for the pickup device were obtained as forward speed vt of 54 m·min⁻¹,rotational speed N of 49 r·min⁻¹,and ground clearance H of 17 mm.Under two-stage harvesting conditions with a peanut plant moisture content of 16%-20%,the pickup rate of peanut plants reached 99.16%,and the pod loss rate was 1.81%.[Conclusion]The field validation test results were close to the optimized theoretical values,providing technical support for the future design of pickup devices for two-stage peanut pickup harvesters.关键词
