摘要
A slot wheeled precision metering device for rapeseeds was designed. The structure and working principle were studied. The metering mechanism mainly consisted of a seed-cleaning wheel axle, a seed-retaining belt and a weed-pushing ringed wire-steel. By experiments, the key structure and performance parameters were analyzed and determined, the lowest seed damage index was obtained when the speed of seed-cleaning wheel axle was 104 r/min, the diameter of shaped hole was 2.8 mm and the inclined angle of wire steel was 33°.
