球勺内窝孔小麦精量排种器投种机理的研究

A study of seed-throwing mechanism on wheat precision seedermeter with ball-spoon shaped inner-cell

简要介绍球勺内窝孔小麦精量排种器结构和工作原理 ,对护种区种子的受力和运动进行了分析 ,通过种子的运动特征 ,着重研究排种轮转速、投种口的位置和尺寸对排种均匀性的影响 。

The paper introduced the configuration and working principle of seedermeter and analyzed the forces and movement state of seed-guarding field from the beginning. The concerns between speed of metering rotor, position and size of seed-throwing mouth and seeding uniformity were discussed by way of movement state of seed. And the parameters were improved.
