摘要
为了提高精密播种机的播种质量 ,避免发生漏种和开沟器堵塞造成的缺苗断垄现象 ,利用红外光敏管作为传感器 ,采用高稳定性的cmos集成电路元件 ,完成了精播机监测器的研究与设计。该装置与 2BJ— 3型气吹式精密播种机配套 ,使用效果良好。
In order to improve the drilling quality, reducing the fail to seeding, a missing seed monitor of precision drill was developed. It is composed of infrared photo sensors triode and high stable cmos-integreted circuit. Using effect of the device is good with 2BJ—3 precision drill forming a complete set.
