Abstract:
In this study, we took the new type of soybean high-speed precision vacuum seed metering as the research object and used the response surface method, to tested its function.The seed cells diameter, vacuum degree, operating speed and seed cells number were as the influence factors and eligible index, rebroadcast index, omitting seeding index and variance index were as the objective functions.Design Expert 7.0 software was used to establish the regression model between the main performance index and the test factors and analyze the effect of the various factors on the performance index.The best combination of parameters were achieved, seed cells diameter was 4.5-5.0 mm, seed cells number was 75-85, vacuum degree was 5 kPa and the operating speed was 9 km. h-1, under this conditon the eligible index was higher than 96，rebroadcast index was less than 2.5, omitting seeding index was less than 1.5 and variance index was less than 20.
