| Abstract: | In view of the existing gas suction millet precise metering device easy to plug holes in planting operation,lead to inaccurate hole grain number and litter eye millet precise metering device in the metering zone due to seed in the eye socket causing metering difficulties and high-speed operation when the issue such as difference of filling effect,using the theory of TRIZ will first some corn seed metering device into contradiction matrix for the problems,and using the principle of 39 engineering parameters,and 40 invention and millet precise seeding technology to innovative design of foxtail millet precise metering device,we design a simple structure,convenient operation of negative pressure type round hole modular millet precise metering device,The single factor test was carried out on the improved seeder.The test results showed that the qualified index of seeder increased first and then decreased with the increase of vacuum degree and rotation speed of hole wheel,up to 85.6%. |
