Simulation and Optimization of Soybean Plot Metering Device with Double Swing Plate
摘要
Abstract
Aiming at the problems of poor adaptability and difficult seed cleaning of soybean seed metering device for plot breeding of soybean,a double swing plate type seed metering device for plot breeding of soybean was designed to improve variety adaptation and seed cleaning through the detachable hole block and seed cleaning plate.The seed metering process was simulated,and the secondary universal rotary combination test was designed to optimize with the hole diameter and swing frequency as test factors and the single grain rate,multiple grain rate and empty grain rate as test indicators.The optimization results was obtained as:the hole diameter was 9～10 mm,the swing frequency was 0.5～1.2 Hz,the single particle rate was more than 60%,the multiple particle rate was less than 30%,and the empty particle rate was less than 15%.Taking the hole diameter of 10 mm and the swing frequency of 1.0 Hz as the test parameters,the bench test and field test were carried out,and the qualification index,replanting index and missed seeding index of the metering device were 75.5%,16.9%,7.6%and 71.4%,18.8%and 9.8%respectively,which were basically consistent with the optimization results.The experiment results showed that the seed metering device can meet the agronomic requirements of plot sowing,and provided a theoretical and reference basis for the design of soybean plot precision seeder.关键词
