摘  要:
为提高电动胶辊旋转式油茶果采摘执行器的采摘效率,设计了一种液压驱动式油茶果采摘机.通过分析油茶果与胶辊相互作用力的影响因素,确定了采摘机的主要工作参数.仿真分析了不同工作参数对油茶果与胶辊相互作用力的影响规律,并以上下组胶辊间距、旋转架转速、胶辊直径为影响因素,以油茶果采摘率和花苞损伤率为评价指标,在江西省林科院和江西农业大学分别进行了室外、室内采摘试验.结果表明,影响采摘率的因素由大到小依次是上下组胶辊间距、旋转架转速和胶辊直径;影响花苞损伤率的因素由大到小依次是胶辊直径、上下组胶辊间距和旋转架转速.结合室内、室外试验,运用综合评分法得出油茶果采摘率较高且花苞损伤率较小的最佳参数组合为:上下组胶辊间距15 mm、旋转架转速55 r/min、胶辊直径30 mm.与电动胶辊旋转式油茶果采摘执行器相比,液压驱动式油茶果采摘机旋转架转速提高了83. 33%,采摘效率明显提高,其平均采摘效率为210个/min.

摘  要:
In order to improve picking efficiency of motor-driven picking actuator of camellia fruit with rotate rubber roller,a hydraulic-driven camellia fruit picking machine was developed. The influencing factors of the interaction force between camellia fruit and rubber roller were analyzed,and the influence rules of different factors on the interaction force between camellia fruit and rubber roller were obtained by simulation. Based on the analysis result,the main working parameters of the picking device were confirmed. Taking the picking rate of camellia fruit and damage rate of camellia bud as experimental indexes,the distance between up and bottom rollers,speed of rotating frame and the diameter of rollers as experimental factors,the orthogonal indoor and outdoor tests were developed in Jiangxi Academy of Forestry and Jiangxi Agricultural University. Experimental results showed that the significant factors affecting the picking rate were represented as the distance between up and bottom rollers,the speed of rotating frame and the diameter of rubber roller. The significant factors affecting the damage rate of camellia bud were represented as the diameter of the rubber roller,the distance between up and bottom roller and the rotational speed of the rotating frame. With the optimal parameter combination,the distance between upper and lower rubber was 15 mm,the rotating speed of rotating frame was 55 r/min,and the diameter of robber was 30 mm,which were verified experimentally with respect to comprehensive performance of the camellia fruit picking machine. Compared with motor-driven picking actuator of camellia fruit with rotate rubber roller,the picking efficiency of hydraulic-driven camellia fruit picking machine was improved obviously,and its speed of rotating frame was increased by 83. 33% and average picking efficiency was 210 per minute.
