    摘要:

    設(shè)計(jì)了水平撥草輪式玉米免耕播種機(jī),確定了撥草輪、開(kāi)溝器和播種覆土裝置等部件的主要結(jié)構(gòu)參數(shù)。田間試驗(yàn)表明,采用動(dòng)力水平撥草輪和刀刃型開(kāi)溝器相結(jié)合的防堵原理,能夠有效清除秸稈、雜草,保證機(jī)具通過(guò)性能。與條帶旋耕式玉米免耕播種機(jī)相比,在滿足種肥深度要求下,土壤擾動(dòng)量減小了69.7%,單位油耗減小了19.3%,較好地滿足了農(nóng)藝要求。

    Abstract:

    The notill planter in horizontal residuethrowing fingerwheel type for maize was designed. The residuethrowing fingerwheel, furrow opener, seeding and covering device were mainly analyzed. Furthermore, the key parameters were analyzed and determined. The field experiment showed that, though adopting the anti-blocking principle that combined horizontal residuethrowing fingerwheel device with residuecutting by knife type opener, the machine could solve the residue and weed blocking effectively and show a good performance of passing and cutting stubble. Compared with striprotating maize notillage planter, the maize notill planter could not only seed and fertilize at the suitable depths, but also decrease soil disturbance and fuel consumption by 69.7% and 19.3%, respectively. It indicated that this new planter could meet the requirements of agronomy.
