Picking Mechanism Analysis and Parameter Optimization of Rotary Vibrating Blueberry Harvester
摘要
Abstract
In order to improve the picking rate of the blueberry harvester and reduce the damage rate to the plant,took the rotary vibration blueberry picker as the research object,and analyzed the form of movement and force when the blue-berry fruit was vibrated,and constructed a fruit-hanging fruit side branch dynamic model;and analyzed the overall structure of the picking device and its movement process:used D'Alembert's principle to establish a theoretical model of the picking device exciter,and analyzed the movement law.Based on the above work,the rigid-flexible coupling dy-namics model of the picking device and plant was established,and the vibration picking force on blueberry fruits was ana-lyzed when the picking device acted on the blueberry plant by taking the angular velocity of the eccentric block,vibration angle and the moving speed of the picking device as the influencing factors,and a single-factor simulation analysis was carried out to make clear the influencing rules of the factors on the force on the fruits and determine the range of values of each factor.Finally,based on the single factor simulation analysis results,the orthogonal simulation analysis of three fac-tors and three levels was carried out.The range analysis method was used to obtain the main and secondary order of the influence of each factor on the fruit stress:vibration angle,angular velocity of eccentric block and moving speed of pick-ing device.The combination of picking parameters that could achieve better fruit harvest rate and reduce plant damage rate were 4.6 r/s angular velocity of eccentric block,21° vibration angle and 60 cm/s moving speed of picking device.关键词
