摘要：Based on the fact of low single seed plant rate, high seed damaged rate and low seed adaptability for conventional and mechanistic precision seed-metering device, a new belt type of seed-metering device was designed (patent No.20101020638.7). both of the 1/4 spherical shape and its size was first established by analyzing the working process of the seed-metering combination the material character of the tested corn seed, and the structure size 6mmX6mm of the seed scoop of this type of seed-metering was then determined by the frame test in agricultural lab, which was tested to own the good work performance. At last, the working adaptability tests were operated, the conclusion showed that the following character indexes were single seed plant rate 98.6%, repeated plant rate 6.3%, leakage plant rate 0.8% and seed damaged rate 0.05% when the size of seed-scoop is 8mmX12mm and the belt speed is 1.05 m/s.
