摘要
英国发明的悬挂在联收机上的摘脱台在中国使用中有两个缺点 :摘脱后的基秆未能切割搂集成条铺和落粒损失 ,尤其在低速时较大。此文报导了用气流吸运脱出物的摘脱滚筒 ,从而省去了原摘脱台上的输送螺旋推运器和输送带 3类的输送装置 ,为了处理大量的脱出物 ,作者发明了立式的“4合 1”处理装置。它具有升运、分离、清选和自循环 4个功能。田间试验表明落粒损失减少 ,作者发明的设置于摘脱流通筒后面的切割搂集装置工作性能良好 :割茬低条铺放在两履带之间。
Stripper header invented by AFRC UK, mounted on grain combine harvester showed its two deficiencies in China: Leaving the stripped straw standing without windrowing and relatively high free grain loss especially working at lower ground speed. This paper reports the invention of a stripping rotor with air suction for pneumatic conveying the materials, eliminating the previous auger and conveying belt on the stripper header. For processing the large amount of threshed materials author invented a vertically positioned “4 in 1” apparatus, performing 4 functions: the elevation, separation, cleaning, and recycling of the materials. Its field trial showed that the free grain loss is reduced and specially invented windrowing device closely behind the stripping rotor located justified itself by the clear cutting with shorter stubble and being center delivered windrow of the straw.
