Research on stripping-threshing technology of clover

Abstract

Biometrical indicators of red clover, agritechnical and energy indicators of a traditional cutting-threshing technology and heat stripping-threshing technology have been researched and harvesting costs of one hectare of red clover have been calculated. Actual fuel consumption an cutting and threshing red clover as well only threshing its stripped heads has been established. Losses of stripping, threshing-separating and overall red clover seed losses when using combine-harvester SR 500 and an experimental stripper have been established in relation with the combine-harvester's working speed and rate of stripping drum revolution. Rational rate of stripping drum revolution for red clover is - 500min-1. Threshing stripped clover heads improves combine-harvester's efficiency 2 times. Compared with traditional technology stripping technology allows to achieve 39% gasoline economy and costs of harvesting one hectare of clover decrease by 57 EUR.
