| Abstract: |
| In the light of problems of traditional full film coverage double furrow sowing maize having low seeding efficiency, easy tearing film, the biofilm formation and inconvenient operation, a jointing ridging, film, and seeding operation machine was designed. The power transmission device of the machine was connected with a crank connecting rod mechanism which was connected by a noncircular gear and a crank connecting rod mechanism connected with a cylindrical gear. Test experiment showed eccentric gear drive type of maize in the whole film double furrow sowing combined operation machine working related indicators have reached machine operation requirements. Also saw non circular gear eccentric rate, non circular gear driven crank and connecting rod length ratio and cutting membrane knife angle as independent variables, film hole enlargement rate as index for testing. The results indicated that it was the best when the elliptic gear eccentricity(E), non circular gear crank and connecting rod length ratio(k) and cutting membrane knife angle(alpha) was 0.1, 0.05 and 31°, respectively, while the film hole expansion rate was 1.22%. |
