Design and Experiment of Rapeseed Precision Hill-Seeder

In this study,in order to implement precision hill-seeding rapeseeds on plastic-film at northwest region in China,solveing problems of precision hill-seeder damage rapeseeds during working, hole type blocking and leakage so-wing,seeding amount is not stable,we design a rapeseed precision hill-seeder. This machine use special-shaped hole on seed metering device to avoid blocking,design u shaped groove to avoid damage rapeseeds, metering seeds and droping seeds to keep synchronization while soil opener opening. Field experiment showed that, statistics on rapeseed precision seeder seeding on film field, count empty hole rate, qualified grain number, qualified seeding depth under film, statistics datas were qualified,the seeder satisfied technical requirements of rape film cultivation.
