    摘要:

    設(shè)計(jì)了一種大豆播種機(jī)偏置雙圓盤氣吸式排種器。通過分析偏置雙圓盤氣吸式排種器取種、排種作業(yè)原理，對(duì)其關(guān)鍵部件進(jìn)行了設(shè)計(jì)、優(yōu)化。以排種器播種吸盤轉(zhuǎn)速、氣流運(yùn)動(dòng)速度為試驗(yàn)因素，漏播率為試驗(yàn)指標(biāo)分別進(jìn)行單因素試驗(yàn)和二次通用旋轉(zhuǎn)組合試驗(yàn)，運(yùn)用Design-Expert軟件得出回歸曲面并建立數(shù)學(xué)模型，得出最佳因素組合為氣流速度220 m/s、排種器播種吸盤轉(zhuǎn)速100 r/min，此時(shí)漏播率為2.72%。

    Abstract:

    A double offset disc air-suction seed metering device for soybean was designed. The key parts of seed metering device was designed and optimized based on the working principles of seed taking and seed metering. The single factor experiments and the quadratic general rotary unitized design were carried out with the rotational speed and air velocity as experimental factors and seed missing rate as experimental index. The regression surface was obtained and its mathematical model was built by using the Design-Expert software. The results showed that the air velocity of 220 m/s and rotational speed of 100 r/min were the best combination factors, which leaded to the seed missing rate of 2.72%.
