摘　　要：设计了大枣自动分级设备。对大枣机构特性进行分析,对大枣自动分级设备工作原理进行研究,设计由振动器、料斗、料斗内侧挡板组成的上料机构;圆柱形筛条轴、锥形筛条轴、隔板组成分级机构;步进电机、锥齿轮、传动带组成传动机构;储料斗、出料通道组成储料装置。对分级设备分级筛条的变形进行有限元分析,确保分级机构能准确运行。An automatic grading equipment of jujube was designed, and its mechanism characteristics and working principle of automatic grading＇were analyzed in this study. This design consisted of feed mechanism for the composition of vibrator, hopper, hopper inside baffle, and the grading mechanism for the composition of cylindrical sieve shaft, conical sieve axis, a baffle plate, transmit mechanism for the composition of stepping motor, bevel gear, belt drive; storage device for the composition of a storage hopper and a discharging channel. The grading equipment of deformation finite element was analyzed, ensuring the classification mechanism ran correctly. More over, the finite element of the deformation of the grade bar was ana lyzed to ensure the accurate operation of the grading mechanism.
