摘　　要：针对‘皇冠’梨采摘后人工剪柄、去袋劳动强度大等问题,设计了1种‘皇冠’梨断柄去袋装置。通过Matlab软件拟合出了纸袋撕裂曲线并计算出了撕袋机械手撕袋运动路径;为优化装置结构参数,设计了3因素Box-Behnken试验,利用Design-Expert软件对试验结果进行方差分析,建立了显著参数的回归模型,获得了‘皇冠’梨断柄去袋装置的最优结构参数:切割间隙为0.89 mm,定位板“V”形定位口角度为36.5°,旋转平台转速为7.8 r/min。此组合下断柄率为90.15%,纸袋撕口平均宽度为50.63 mm,研究结果可为‘皇冠’梨断柄去袋装置设计与改进提供理论基础。Aiming at the problems of manual cutting of the handle of the crown pears after picking that requires the high labor intensity for bag removal,a handle-breaking and bag-removing integrated machine was designed,and its handle-breaking device was optimized.Matlab software was used to calculate the bag removal movement of the bag removal robot Trajectory.In order to optimize the structural parameters of the device,a three-factor Box-Behnken test was designed.The design-Expert software was used to analyze the variance of the test results,and a regression model of significant parameters was established to obtain the optimal structure of the crown pear broken handle and bag removal device Parameters.The cutting gap was 0.89 mm.the"V"-shaped positioning opening angle of the positioning plate was 36.5°,and the feed per tooth was 7.8 r/min.With this combination,the broken handle rate was 90.15%,and the average width of the paper bag tear was 50.63 mm.The research results can provide a theoretical basis for the design and improvement of the device for removing the broken handle of the crown pear.
