摘　　要：针对英国发明的摘脱台的两个缺点，即摘脱落粒损失率较高和纵向尺寸过大难以在其后设置摘脱后禾秆切割搂集机构，作者研究出借助气流吸运脱出物的割前摘脱联合收获机。它具有适于处于前倾状态的禾秆切割的贴地仿形切割搂集机构和适于大喂入量的具有升运、分离、清选与复脱“四合一”的脱出物处理装置。Stripper header invented by AFRC, UK, mounted on grain combine harvester showed its two shortcomings: Leave the stripped straw standing without windrowing and high level of shattering loss. 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 largely increased amount of threshed materials the author invented a vertically positioned “4 in 1”apparatus, performing 4 functions: the elevation, separation, cleaning, and rethreshing of the materials. The field trial of that machine showed that the shattering grain loss is significantly lower than that in stripper header and specially invented windrowing device justified itself by its clear cutting with lower stubble and being laid in good order windrow of the straw.
