摘　　要：针对水田耕整农艺要求,设计了一种能够一次作业完成碎土、根茬压埋、根系生长土层起浆以及平地等多道工序的水田振捣起浆平地机,主要由机械传动装置、机械式高频激振机构、圆弧埋茬梳齿、船型拖板以及新型隔震传动装置组成。通过分析确定了机械传动装置参数,并设计了水田振捣起浆机的机械式高频激振机构和圆弧埋茬梳齿。田间试验表明:当机械式高频激振机构的激振频率为43Hz、机具前进速度为3km/h时,埋茬率为90.6%,平整度为20mm,泥浆度为1.30g/cm 3,综合指标达到最佳,满足水田耕整的农艺要求。According to the agronomic requirements of paddy field tillage,a paddy field vibration pulping grader is designed,which can complete multiple processes such as soil crushing,stubble burying,root growth,soil layer pulping and leveling in one operation.This type of machine is mainly composed of mechanical transmission flexible shaft,mechanical high-frequency excitation mechanism,circular arc stubble comb,ship carriage and new isolation transmission device.By analyzing and determining the parameters of mechanical transmission flexible shaft,mechanical high-frequency vibration excitation mechanism and according to the working principle of circular arc stubble comb,a paddy field vibration pulping and leveling machine is designed.The field test shows that when the excitation frequency of the mechanical high-frequency excitation mechanism is 43hz and the forward speed of the machine is 3km/h,the stubble rate is 90.6%,the flatness is 20mm and the mud degree is 1.30g/cm 3.The comprehensive index reached the best and met the agronomic requirements of paddy field tillage.
