STUDY ON CUTTING PARAMETERS OF DISC CUTTERS ON SOYBEAN REAPER

Soybean is one of main economic crops in China. Owing to rising of its price, soybean field is greatly extended in recent years. However, the demanded size of soybean reaper is getting smaller since the production units become small, which is dominated by current government policies. To meet this requirement, it is urgent to develop a small sized reaper for soybeans.In the paper, by means of experimental design, computer simulation, and neural optimization methods the analyses and researches on disc cutter were conducted. The effects of cutting speed, cutting angle, tooth height of disc cutter on cutting loss and cutting resistance were investigated. The relations among cutting speed, cutting angle, tooth height, cutting loss and cutting resistance were established by polynomial regression. The optimal combination among three factors of cutting speed, cutting angle, tooth height was gained. The results show that it is feasible to cut soybean by a disc cutter. The cutting resistance is small and the cutting loss is less than 15 %.
