摘要
针对当前木薯收获设备存在问题,基于木薯宽窄双行起垄种植农艺要求,确定木薯收获机工作原理与总体结构,并对挖掘铲、偏心套机构、振动链排、过载保护装置等关键部件进行讨论与分析,设计了4UML-130型振动链式木薯收获机,该机一次作业能够完成木薯块根的挖掘提升、薯土分离输送、平铺地表等工序。作业时,轮式拖拉机跨垄行走在相邻垄沟中,便于机手操控,收获过程中不压伤木薯块根,实现了垄上木薯有效对行收获。田间试验表明,4UML-130型振动链式木薯收获机完全符合木薯宽窄双行起垄种植农艺机收作业要求,明薯率95.8%、损失率5.4%、生产率0.42 hm^(2)/h,满足设计要求。
To solve the problem cassava harvesters,4UMG-140 poking roller type cassava harvester was designed according to agronomic requirements of cassava wide-and-narrow-double-row ridge planting model.In this paper,working principle and gross structure of the designed harvester are introduced,and its key components including digging shovel,eccentric sleeve,vibration chain and over load protection device are discussed and analyzed.The combine harvester can complete root digging and separating from soil,root conveying and lifting and root lying on land in one operation.The harvester realizes efficient harvesting with tractor wheels running in furrows between ridges in harvesting without rolling on and damaging cassava roots,which is convenient for tractor driver's operation.Field experiments showed that 4UML-130 rear-collected type cassava combined harvester could meet with the mechanical harvesting requirements of cassava planted with wide-and-narrow-double-row ridge planting model.With obvious cassava rate 95.8%,loss rate 5.4%and productivity 0.42 hm^(2)/h,the harvester could satisfy the design requirements.
