Abstract:
Abstract: In order to solve the problem of manual seed replacement in seeding different types soybean seeds in modern plot breeding, improving the seeding efficiency, a new automatic turntable soybean seed supplying device in plot seeders was designed. The whole construction of the device was composed of the round seed plate and some seed cups. All the seed supplying process was realized through a motor controlled by PLC. The electrical automatic seed supplying device was composed of the mechanical section and the electronic control section. The mechanical section was composed of seed cups, seed plate, pedestal and so on. The electronic control section was determined by hardware selection and parameter calculation. In this paper, theoretical analysis and structural design of seed cups were completed, DC stepping motor control was realized by the software design. The results of the platform experiment showed that, the maximum of the seed cup offset qualified rate was 99.6%, the maximum of the perfect seed rate was 99.836%. It had great accuracy and reliability and can meet the agricultural requirement of the plot seeders.
