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

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 m2/h while the area of manual spraying was 1 000-3 000 m2/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.
