垂直圆盘气吸式排种器攫取种子过程分析

Analysis Process of Grabing Corn Seed of Vertical Disc Air-suction Metering Device

目前,我国玉米精量播种面积较大,其中采用垂直圆盘气吸式播种技术进行播种的较多,但该项技术在高速作业时存在排种器攫取种子效果不佳的问题,即出现少播或漏播的现象。为此,针对该问题开展相关技术研究,从理论上对垂直圆盘式气吸式排种器攫取种子的过程及有关参数进行分析,找出解决该问题的方法,提高机械化作业效率。

Present,China's sown area of corn precise large,the vertical disc air suction seeding planting more,but the technology in high-speed operation,the metering device to grab the seed in effective,appears less multicast or the leakage broadcast phenomenon.In this paper,the problem to carry out related research from the theoretical vertical disc air suction type metering device to grab the seed process and the parameters analyzed,to find a solution to the problem and improve the efficiency of the mechanized operations.
