experiments on variable-mass threshing of rice in the tangential-longitudinal-flow combine harvester
the existing studies of threshing process of combine harvesters adopt the assumption of constant mass, which is contradictory to the phenomenon of separation of grains and short stalks in actual threshing process. therefore, the characteristics of threshing and separation are not accurately described. aiming at this problem, this study established the tangential-longitudinal threshing and separ...
متن کاملبررسی اثر سرعت خطی کوبنده و رطوبت محصول روی تلفات و ضایعات کوبش ارقام متداول برنج
A considerable portion of threshing losses and waste of rice takes place in threshing stage. One of the effective factors in threshing losses and waste of threshing units, threshers and harvesting machines, is the drum speed. In this research, effects of three factors including drum speed (five levels), crop moisture content (two levels) and rice common varieties (four varieties) on threshing l...

متن کاملeffect of drum and concave characteristics and crop moisture on cumin threshing quality
cumin is an annual plant suitable for dry and semi-dry regions. it is harvested at two stages to prevent seed shedding. first, the cumin bushes are harvested by hand or using a scythe. after drying, the cumin bushes are beaten with a stick or trampled using animals or a small tractor. this harvesting method is time consuming, requires intensive labor and is an incomplete threshing process resul...
