摘　　要：为设计一种新的播种机排种装置,使内切推种轮能平稳地配合于排种轮的直孔中,依据两轮切点位移变化,推导出传动比为2和4时配合齿轮曲线方程。依此曲线方程成功设计出多功能精密排种器推种轮齿形曲面。In order to avoid seed blockage at the hole of sowing wheel a new seed metering device of sowing machine was developed. The technological parameters, working principle and structural characteristics of the key components were introduced. The equations of curved surface of seed pushing wheel are derived. The research results can be used as basis for designing new sowing machine.
