Design of Device for Raising Seedling and Seeding in Aperture Disk

According to demands for rice seedlings throwing, the device for raising seedling and seeding in aperture disk was designed and developed. Its working principle and design of rubber belt for conveying seeds were mentioned in the paper. The design scheme was superior after tested by experimentation. Under the condition of superior parameters, best factors combination for seeding in aperture disk with small quantity of seeds can be singled out and optimal seeding performance of the device can be obtained.
