针对目前排种器排种精度不高、稳定性差、排种不均匀及调整范围小的缺点 ,设计了一种光电控制电磁振动排种器。该排种器以 PIC16 F 877为核心 ,采用光电控制技术 ,使得排种器每个工作循环可排 1～ 12 5粒种子。该排种器每次排种粒数可由按钮开关采用 2进制的方式在 1～ 12 5之间任意设定 ,改善了其排种稳定性和排种均匀性。可以方便地调整排种量 ,并可根据需要单步或连续排种。试验结果表明 ,该排种器具有高的排种精度 :单粒率大于 98%,漏播率为 0。
Aiming at the shortcomings of the current seeder seeding precision is poor, the stability is poor, the seed row is uneven and the adjustment range is small, a photoelectric controlled electromagnetic vibrating seed metering device is designed. The seed metering device uses the PIC16 F 877 as the core and uses photoelectric control technology to make 1 to 125 seeds for each working cycle of the seed metering device. The seed metering per seed can be set by the button switch in binary mode between 1 and 125, which improves the seed stability and seed uniformity. Can easily adjust the amount of planting, and can be single step or continuous rowing as needed. The test results show that the seed metering device has high seed metering accuracy: single grain rate is greater than 98%, the rate of 0 is 0.
