摘要:
从控制超大片率、保证大中片率出发,分析了烟叶复烤线打叶框栏对打叶的影响,提出了将一级打叶器上框栏开孔制作成不同尺寸以改善打叶后的叶片结构的措施:将3,4,5,排框栏的孔径改为110 mm×(80±1)mm;将1,2,6,7排框栏孔径改为110 mm×(72±1)mm.改进后,大中片率由86.9%提高到87.6%5,0 mm×50 mm以上超大片率由26.2%减少至21.6%.
Abstract:
To control the percentage of oversized tobacco leaves and ensure the large and medium,the effect of the thresher frame's tobacco redrying line on threshing quality was analyzed.The measure that the frame's openings size of first class thresher was made into different sizes to improve the leaf structure was put forward.After improvement,the aperture of the third,the 4th and the 5th rows of the frame was changed into 110 mm×(80±1) mm and the aperture of the first,the second,the 6th and the 7th rows of the frame was changed into 110 mm×(72±1) mm respectively.As a result,the percentage of large and medium tobacco leaves raised from 86.9% to 87.6%,the percentage of the 50 mm×50 mm scaled out tobacco leaves decreased from 26.2% to 21.6%.
