| 摘 要： | 气吸式、指夹式和倾斜勺式3种玉米精密排种器具有不同性能和最佳工作速度.通过在台架上进行性能对比试验,分析了在不同速度下各类型排种器粒距合格指数、重播指数、漏播指数及合格粒距变异系数的变化趋势,得出不同排种器的最佳工作速度.试验结果表明:随着工作速度的增加,各类型排种器性能均下降,且最佳工作速度不同.其中,倾斜勺式的最佳工作速度为10km/h,气吸式和指夹式的均为6km/h左右. |

| Abstract: | Three kinds of corn spacing seed feeder i.e.suction feed,finger pickup feed and inclined spoon feed had different performance and the best working speed.Variation trend of the four performance parameters that percent of qualification seed spacing,percent of multiples,percent of miss and variance of qualification seed spacing,were analyzed under different working speed.And the best working speed is educed through rig test.The testing results indicated that all the three feed performance declined along with w... |
