摘要
为解决东北大红萝卜收获机械化较低,收获速度较慢,劳动强度大等突出问题,采用数理统计方法对大红萝卜的自然生长特性进行分析,得到了大红萝卜的直径、质量、食用根长度、食用根土下埋藏深度的分布区间等相关数据,为大红萝卜收获机设计提供了必要的理论依据。对大红萝卜收获机的挖掘机构进行了分析,建立了挖掘铲的力学模型,得到了挖掘摩擦力、挖掘阻力随挖掘铲铲面倾角变化的关系曲线图,为挖掘铲的铲面倾角设计提供了理论依据。从挖掘铲铲柄间距、挖掘铲长度、入土深度、铲面宽度、铲刃角等角度对挖掘铲结构进行了分析与设计,为大红萝卜收获机研制进行了技术储备。
In order to solve the obvious problems such as low mechanization,slow harvest speed and high labor intensity of Raphanus sativus harvesting in Northeast China,the natural growth characteristics of Raphanus sativus were analyzed by mathematical statistics method.The related data of diameter,quality,length of edible root and distribution range of buried depth under edible root soil were obtained,which provided a necessary theoretical basis for the design of Raphanus sativus harvester.The excavation mechanism of the Raphanus sativus harvester was analyzed,and the mechanical model of the digging shovel was established.The relationship curve of excavation friction and resistance with the dip angle of digging shovel surface were obtained,which provided a theoretical basis for the inclination angle design of the digging shovel.The structure of digging shovel was analyzed and designed from the angles spacing of shovel handle,length of shovel,depth of soil entry,width of shovel face and angle of shovel edge,which provided technical reserve for the development of Raphanus sativus harvester.
