| Abstract: | Aimed to the problem that the transmission axis of the multiple functions of precision seed-drilled appliance is not in the center of the seed-drilled wheel,the new curve for seed pushing wheel was applied,to lower the location of seed pushing wheel,and locate the transmission axis in the center of the seed pushing wheel.Furthermore,the aperture and number of the seed pushing wheel for different seeds were investigated,and the seeds amount of per hole,the rates of broken seeds and the reliability were all m... |
