Abstract:
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．
