摘要
木薯机械化种植是产业可持续发展的趋势,漏播漏种是制约木薯种植机推广应用的关键问题。为此,在自主研发的实时切种式木薯种植机基础上,采用光电传感器,结合单片机技术和自动控制技术,设计开发木薯种植机漏播监测与标记系统,漏播处撒播石灰标记,为后续人工补种提供位置参考。为验证工作的可靠性,对漏播监测系统和漏播标记系统进行试验验证。试验结果表明:在拖拉机前进速度2.5km/h、刀辊转速4.5r/min条件下,标记率平均在80%以上;在拖拉机前进速度0.7km/h、刀辊转速4.5r/min条件下,系统对漏播量的监测精度达到81.57%,播种量的监测精度达到98.28%,系统可为木薯补种提供较可靠的位置信息。
Mechanized planting is the trend of sustainable development of the cassava industry,the key problem of the application of cassava planter is seeding absence.In this study,monitoring and marking system for real-time cassava planter was designed and developed by using photoelectric sensor,combined with single-chip microcomputer technology and automatic control technology.The lime mark is scattered in the seeding absence area to provide the reference for the following artificial reseeding.In order to verify the reliability of the system,a experiment was carried out under the conditions of 45 rad/min rotation speed of seed-cutting and metering device,2.5 km/h forward speed,and 0.6 m plant distance.The results showed that,the average error rate of the information collection system was 1.47%,and the average marking rate of the marking system was 88.6%.The missing position marked by the system can provide more reliable data of the missing position.
