为了解决黏重土壤条件下百合收获时果土分离效果差、埋果率高、破碎率高的问题,设计了一种适合黏重土壤条件下作业的抛送辊式百合收获机。结合百合生长状况以及种植农艺要求,对果土混合物在振动输送装置、抛送辊组上的运动过程及分离作业...展开更多 为了解决黏重土壤条件下百合收获时果土分离效果差、埋果率高、破碎率高的问题,设计了一种适合黏重土壤条件下作业的抛送辊式百合收获机。结合百合生长状况以及种植农艺要求,对果土混合物在振动输送装置、抛送辊组上的运动过程及分离作业机理进行分析,构建了黏重土块在抛送辊上抛掷碎土、碰撞碎土的动力学模型,通过分析得到了振动输送装置结构及最...

Lily bulb is an underground tuber crop, which is mainly grown in southern China. At present, lily bulb harvesting mainly adopts manual excavation, resulting in low labor efficiency. Coupled with the high soil viscosity in lily bulb planting area, there are some problems in lily bulb mechanized harvesting, such as difficulty in fruit-soil separation and high damage rate of lily bulb. In order to solve the problems of poor separation effect, high rate of buried fruit and high crushing rate during lily bulb harvest in sticky soil, a kind of throwi...
