Design of Electromagnetic Vibration-Type Single-Bud Sugarcane Seed Metering Device

The objectives of this research were to solve the problem that the existing sugarcane seed metering device had high per cent of damaged seeds and omission rate. An electromagnetic vibration-type single-bud sugarcane seed metering device was designed. It made use of the characteristic of vibrating automatic metering to avoid damaging buds. And it could be adjusted to different sowing speeds by setting the controller. The migratory mechanism was analysed. The helix angle and working parameters of the metering device were obtained by the experiment. The results of the experiment showed that the order of factors affecting the qualification rate was amplitude > frequency > helix angle. The best qualification rate of the metering device was achieved when the helix angle was 6°, the amplitude was 0.4 mm and the frequency was 53.2 Hz, and the results of verification experiments showed that the qualification rate of metering was over 80% and the per cent of damaged buds was 0 with the best parameter combination. This metering device met the standard requirements of sugarcane seeds metering.
