Rice (Wheat) Combine Harvester With Cutting and Windrowing Straw Immediately After Stripping

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.
