Abstract:
In order to realize the purpose of saving seeds in the single-seed precision metering of soybean seeding, this research used EDEM software to take the simulation test on the inside-filled soybean seed-metering device for five soybean varieties commonly grown in the Huanghuaihai region of China. We analyzed the effect of seed-metering device working speed on the single-seed rate with simulation test and performed bench test. The result showed that the single-seed rate was 90.81%-95.42%, and the working speed of the seed metering had a significant effect on the single-seed rate. The working speed of the metering device was 30 r·min-1, all five types soybeans performed the single-seed rate, the signle-seed rate, resowing rate and omission rate were respectively 89.88%-94.13%, 4.75%-9.61% and 0.12%-2.04%. The test values were in line with the industry standards for the working performance of the seed metering device. The maximum error between the simulation results and the bench test results was only 4.39%, and the simulation design can provide a theoretical basis for the optimization of the key components of the seed metering device.
