针对目前水稻轴流联合收获机脱粒分离装置工作时功率消耗大、脱出物含杂率高、增加清选工作负荷等实际问题,自行研制了一种钉齿式轴流装置,并进行了水稻脱粒分离试验。分别建立了喂入量、滚筒转速和凹板间隙与功耗、含杂率、断穗率、总损失率4个性能评价指标的数学模型;得出了影响性能评价指标的因素主次顺序;借助Matlab软件进行了多目标优化,得到了该装置的最佳工作参数组合:喂入量2kg/s,滚筒转速600r/min,凹板间隙30mm,并进行了验证试验。由此为我国水稻联合收获机的研发和传统机型改造提供了理论依据。
針對目前水稻軸流聯閤收穫機脫粒分離裝置工作時功率消耗大、脫齣物含雜率高、增加清選工作負荷等實際問題,自行研製瞭一種釘齒式軸流裝置,併進行瞭水稻脫粒分離試驗。分彆建立瞭餵入量、滾筒轉速和凹闆間隙與功耗、含雜率、斷穗率、總損失率4箇性能評價指標的數學模型;得齣瞭影響性能評價指標的因素主次順序;藉助Matlab軟件進行瞭多目標優化,得到瞭該裝置的最佳工作參數組閤:餵入量2kg/s,滾筒轉速600r/min,凹闆間隙30mm,併進行瞭驗證試驗。由此為我國水稻聯閤收穫機的研髮和傳統機型改造提供瞭理論依據。
