| 摘 要： | 针对一年两熟地区免耕播种机播种小麦时存在的问题，提出以驱动缺口圆盘刀作为切断覆盖玉米秸秆、根茬装置，该装置的缺口圆盘平面中心垂直线与刀轴的轴线有一个较小夹角(7°)。通过对该装置的运动分析和土槽试验，确定主要基本参数。当刀轴转速为350 r/min时，消耗功率为1.7 kW，并能够有效切断秸秆根茬。开出沟槽的地表宽度为56.7 mm。 |

| Abstract: | A driven gap disc cutting mechanism for treating corn stalk and rootstalk was developed for no-till drill in the areas of two crops a year. For width of disturbance of soil surface, the angle between the disc plane and its axes is necessary and smaller. By motion analysis and the soil bin experiments of the mechanism, the key parameters were optimized. The rotor speed being 350 r/min, the mechanism has a good ability to cut corn stalk and rootstalk, and the installing angle of the gap disc being 70°, the power consumption is 1.7 kW and the width of disturbance of soil surface is 56.7 mm. |
