摘要 针对现有马铃薯播种机播种精度低、株距和振幅调整麻烦等问题,在现有马铃薯播种机的基础上设置了智能株距控制装置,当检测到播种机的行驶速度等信息发生变化时,将控制电液伺服阀实时自动修正液压马达转速,保证播种株距合格率始终控制在允许范围内;设置了智能重种漏种控制装置,当检测到的薯种信号多于1枚或未检测到薯种信号时,控制步进电机实时调整输送带及其薯种碗的振动强度,结果表明,实际漏种率ξls为6.4%-7.9%,实际重种率ξcs为8.2%-10.1%,较佳的允许漏种率ξly的设定范围为6.0%-8.0%。该智能控制马铃薯精密播种机有效地提高了播种精度和作业效率,提高了马铃薯播种机对不同地区、不同马铃薯品种的适应能力。 In order to solve the problems of low seeding precision, difficult row spacing and amplitude adjustment ofpotato planter, this experiment installed intelligent row spacing devices on existing potato planter. The device ofintelligent row spacing would auto-correct the electro-hydraulic servo valve to correct speed of hydraulic motor, whenit detected the change in planter speed, etc. messages, so as to assure the qualification rate of row spacing within apermissible range. When the device detected more than one potato seed message or did not detect any message, itwould adjust the conveyor belt and vibration intensity of potato seed bowl classifier. The result showed the actualmissing rate ls was 6.4%- 7.9% and resetting rate was 8.2% - 10.1%, and the better allowed missing rate ly was6.0%- 8.0%. This intelligent controlled potato precision drill could effectively improve the seeding accuracy andoperation efficiency. At the same time, it also improved its adaptability to different areas and different potato varieties.
