组合内窝孔玉米精密排种器的试验研究

Experiment Study on Precision Maize Seed Metering Device of StepTypeInnerCell

为了满足日益增长的玉米精播要求，特别是满足以简单的结构、方便的操作进行精播的要求，设计了具有阶梯形内窝孔的组合内窝孔玉米精密排种器。通过对该排种器的实验研究得知，只要正确地选择阶梯形内窝孔的形状和尺寸参数，该排种器可对不同品种的玉米种子，在不分级的情况下，达到精播要求。

In order to satisfy the needs for maize precision planting, especially for precision planting with a metering device which is simple in structure and convenient in use, a seed metering device of steptypeinnercell was developed. The experiment results showed that when the shapes and sizes of the device were properly taken, the seed metering device will satisfy the needs for precision planting different varieties of maize seeds, without seed separation by size.
