设计了2BM-6型滚轮式玉米免耕播种机,确定了拨草轮、穴播轮、成穴器和镇压轮覆土装置等部件的主要结构参数。田间试验表明,采用动力水平拨草轮防堵原理,能够有效清除秸秆、杂草,保证机具通过性能。与条带旋耕式玉米免耕播种机相比,在满足种肥深度要求下,土壤扰动量减小了69.7%,单位油耗减小了19.3%,较好地满足了农艺要求。
2BM-6 roller-type no-till corn planter was designed and the main structural parameters of the grass-planting device such as the turf grass, podcasting wheel, cavitation and repression wheel were determined. Field experiments show that the use of power level turf plugging principle, can effectively remove straw, weeds, to ensure that the machine through the performance. Compared with the strip rotary tillage corn no-till planter, under the requirement of seed fertilizer depth, the amount of soil disturbance decreased by 69.7% and the unit fuel consumption decreased by 19.3%, which met the requirements of agronomy better.
