针对丘陵山区地形复杂导致我国地面植保喷雾机械入地难、植保效果差等问题,设计了一种丘陵果园单轨遥控自走式弥雾机,采用轨道设计与弥雾机械相结合的方式,通过理论分析与计算,对控制系统、运输轨道系统和风送喷雾系统进行了设计与选型.田间试验结果表明,该轨道弥雾机行驶速度 0.7 m/s、最大爬坡度 40°、最大遥控距离 200 m;整机最小离地间隙 600 mm;苹果树内部枝叶正、反面药液覆盖率分别为 43.20%和 21.80%,苹果树外部枝叶正、反面药液覆盖率分别为 72.26%和 35.12%.该轨道弥雾机整机运行平稳、安全可靠、遥控信号稳定及植保作业效率高,可为我国丘陵山区复杂地形植保作业机械设计制造提供借鉴与参考.
Design and Experiment of Single Track Remote Controlled Self-propelled Misting Machine for Orchard in Hilly and Mountainous Area
In order to solve problems of difficult entry of spray machinery for plant protection and poor plant protection effect due to complex terrain of hilly and mountainous areas,a single track remote controlled self-propelled misting machine for hilly orchards was de-signed.Through theoretical analysis and calculation,control system,transport track system and air supply spray system were designed and selected by combining track design with mist spreading machinery.Field test results showed that track misting machine has a driving speed of 0.7 m/s,a maximum climbing slope of 40 °,and a maximum remote controlled distance of 200 m;the minimum ground clear-ance height of entire machine was 600 mm;coverage rates of internal branches and leaves of apple tree were 43.20%and 21.80%,re-spectively,while coverage rates of external branches and leaves of apple tree were 72.26%and 35.12%,respectively.The track mist-ing machine runs smoothly,is safe and reliable,has stable remote controlled signals,and high efficiency in plant protection opera-tions.It could provide reference and guidance for design and manufacturing of plant protection machinery in complex terrain of hilly and mountainous areas in China.
