摘要
通过对气力轮式排种器型孔流场的测量、实验及分析,阐明了型孔中的气流具有捕获、推入和稳定种子的作用。这对认识种子入孔机理及设计类似部件均有参考价值。
The effects of air-flow are explained through measuring, testing and analyzing the flow field of cell bore in the pneumatic wheel-type seed-metering device (PWSD). The air flow in the cell bore is able to catch, push and stabilize seeds in cell bores. This paper is of help for understanding the mechanism of seed filling into bores and can serve as reference to designing similar device.
