小型无线遥控和实时配药喷施机的研制

Development on small pesticide spraying machine with real-time mixing and remote-control spraying

为解决某些需要小型质保机械作业,而人工喷施农药工效较低且喷施过程中农药对操作人员身体的危害等问题,该文设计了以单片机为处理核心的无线遥控农药喷施机,并采取边喷施边配制的工作方式。该喷施机由蓄水箱、喷施系统、喷杆调节系统、行进系统、供电系统、无线遥控系统等组成,样机机身质量约为41.5kg,并对样机进行测试。测试结果表明,该农药喷施机行进速度最快可达1500m/h,性能平稳且可靠,最大可喷施面积为8000m2/h(而传统的手工喷施面积为1000～3000m2/h),喷施工效约是人工喷施的2～3倍,且通过远距离遥控完成喷施过程,保证了操作人员的安全,又因边施边配可避免喷施药液配制过多而造成农药的浪费及对环境的污染。

In order to using small warranty pesticide spraying machine in some certain areas and overcome low efficiency of manual spray and remove the hazards on the operators in the spraying process, a pesticide spraying machine was developed based on the single chip computer and the technique of wireless remote control. The machine was composed of a water storage tank, a spray system, boom control system, a running system, a power supply system and a wireless remote control system. The sample machine was 41.5 kg and was tested. The testing results showed that the speed of the machine was as fast as 1 500 m/h, performance of which was stable and reliable, the maximum spraying area was 8 000 m^2/h while the area of manual spraying was 1 000-3 000 m^2/h, and spraying speed was 2-3 times of the manual spraying speed. The machine can guarantee the safety of operator by completing the spraying process using the remote control and can reduce the pesticide waste and remove environmental pollution because the way of online spraying and preparation simultaneously.
