Abstract: This paper described the determination of a general scheme on a kind of no-tillage half-precision seeder and parameter selection and the structural design of its main working parts. The machine solves the twining and jams by crop residue on the machine during the no-tillage sowing. That avoids the extreme resistance on the machine, mixture of the fertilizer and seeds,soil disturbance and other issues caused by earth hilling. This machine is simple in structure,convenient in operation and low costs in manufacture and it is a multi-purpose machine,which is suitable for spreading and application in small and medium farms or specialized households.
