红枣分级机的设计 摘要 随着红枣的大范围种植，红枣收获后分级成为了最主要的问题，红枣分级后会带来更大的经济效益，所以红枣分级就是提高产品价值和档次的关键技术之一。 本次设计的红枣分级机由栅条滚筒、导向装置、喂料装置、出料装置、传动部分等组成。其中栅条滚筒根据红枣的腰径尺寸分为了3个等级，栅条滚筒的转速为47r/mi
n，滚筒的直径为600mm。导向装置是用螺旋杆，螺旋杆可以防止红枣堆积在滚筒底部，可以防止红枣的窜级。最后对关键零部件进行校核，并使用AutoCAD绘制整机装配图和零部件图。该机的分级的效率约为500kg/h，具有一定的实际应用价值。 关键词：红枣；分级机；栅条滚筒；螺旋导向装置 Desig
