Abstract:
In order to solve the problem of poor seeding and low rate of single particle,a high-speed precision vacuum seed metering was designed.The structure designing and the theory calculating for the key components were conducted,and the preliminary experiment of seeding performance was carried out.The experimental results showed that when the speed in operation was 7,8,9,10 and 11 km·h-1,the eligible index could obtain greater than 94,omitting seeding index less than 2.5,rebroadcast index less than 3.3 and variation coefficient less than 20,the experiment results were good.The seed metering could meet the requirement of high-speed precision seeding.
