| 摘 要： | 针对用于一年一熟区免耕播种机的尖角型开沟器易磨损,且磨损后导致土壤扰动大、动力消耗增加、影响播种质量等问题,研究了能够拆卸前刀的楔刀型免耕开沟器以及传动机构,设计了刃口为圆弧形的前刀,并在此基础上设计了2BMX-5型小麦-玉米免耕播种机。样机分别在内蒙古、宁夏等小麦、水稻茬地进行了性能试验。试验结果表明,该机在播种过程中未发生堵塞,楔刀型免耕开沟器提高了通过性,开沟破茬效果良好,播种后土壤扰动小,种肥深度能够满足播种要求,在稻茬地的破茬率超过85％。

| Abstract: | A new no-till seeder,named 2BMX-5 no-till wheat-maize seeder,has been developed by China Agricultural University to solve the new problem of no-till seeder which the openers was braded that led to increase soil disturbance and fuel consumption in the area of one crop per year of North China.The wedge-shaped with front knife no-till opener consisted of front blade and pedestal and new driving device have been designed,and the split front blade was also designed.Field performance test was made in the field co... |
