烟拐剔除筛的改进及烟梗分选筛清理装置的设计

Improvement of Stalk Epidermis Flap Shaker and Design of Cleaning Device for Stem Sieve

烟拐剔除筛和烟梗分选筛筛网存在烟拐和烟梗堵塞的问题,为此改进了烟拐剔除筛筛网网板的支承方式,保证了烟拐顺利前移,实现了网板的自动清理,有效地改善了烟拐、烟梗的分离效果;在烟梗分选筛筛网网板上增设了一套清理装置,可以及时清除堵塞的烟梗,使筛网的开孔率保持不变,保证了长、短梗的有效分离。

Aiming at the problems of screen blocking in stalk epidermis flap shaker and stem sieve, the support of screen plate in the flap shaker was improved to allow the flaps to pass over the screen smoothly, the screen was thus self-cleaned, the effect of separating flaps from stems increased effectively; the blocked stem could be removed timely by a set of cleaning device added over the screen plate of stem sieve, to keep a constant opening ratio of screen, the effective separation of long and short stems was ensured.
