摘　　要：针对我国玉米种植区域秋季收获后进行条耕作业时条带清洁率低、清洁宽度不稳定、受长秸秆缠绕发生堵塞等问题,设计了一种独立仿形的条带清垄机构。对秸秆切断结构进行了运动分析,确定了缺口圆盘切刀的类型和尺寸;对拨茬轮结构形式进行选型与分析,得出影响条带清洁率与清洁宽度的主要因素为拨茬轮半径、拨茬轮倾角和拨茬轮偏角;以条带清洁率、清洁宽度为技术指标,利用EDEM进行二次旋转正交组合试验,确定了最佳的作业组合参数为拨茬轮半径160 mm、拨茬轮倾角10°、拨茬轮偏角30°。田间试验结果表明:切刀入土深度100 mm时,清洁率为92.2%,清洁宽度在240~260 mm范围内,与仿真效果基本一致,满足条耕作业的农艺要求。In order to solve the problems of low strip cleaning rate,unstable cleaning width,and blockage caused by the winding of long stalks during strip tillage after autumn harvest in China’s corn planting areas,an independent profiling strip ridge cleaning mechanism was designed,the movement analysis of the straw cutting structure was conducted,the type and size of the notch disc cutter were determined,and the structural form of the stubble wheel was selected and analyzed.The main factors that affect the cleaning rate and width of the strip were:the radius of the stubble wheel,the inclination angle of the stubble wheel,and the deflection angle of the stubble wheel.Taking the cleaning rate and cleaning width of the strip as technical indicators,a quadratic rotation orthogonal combination experiment was conducted using EDEM.The optimal operating combination parameters were determined to be the radius of the stubble wheel of 160 mm,the inclination angle of the stubble wheel of 10°,and the deflection angle of the stubble wheel of 30°.Field validation experiments were conducted on it,and the experimental results showed that the cleaning rate was 92.2%and the cleaning width was between 240-260 mm when the cutting blade was inserted into the soil at a depth of 100mm,which was basically consistent with the simulation effect and met the agronomic requirements of strip tillage operations.
