電動自走鼓風噴霧機之開發

本研究目的為研製電動載具，承載噴霧系統，並進行行走及噴霧性能試驗。研製完成的電動自走鼓風噴霧機之車身尺寸為1,900×750×1,300 mm，轉彎半徑約4.8 m，行走速度介於0.5至7.4 km/hr之間，在電瓶充飽電力下之作業時間約為6 hrs；全機包括行走馬達、噴霧幫浦及鼓風馬達均採用電力驅動，試驗之管路壓力達7 bar，噴架結構為左右側二支噴桿各裝4粒Teejet 11001VHXL噴頭，噴桿裝設於向左右二側噴出的電動鼓風機出風口，其噴霧流量在7 bar壓力下為4.8 l/min，每粒噴頭流量約為0.6 l/min。最大負載下車體起動瞬間之最大電流約為82 A，大電流維持約2 sec，接著不到1 sec的時間內，電流瞬間降至20 A以下。其間電壓在最初1 sec內升至21.6 V，接著大電流期間的電壓值約21.4 V～22.8 V之間，最後電壓值升至約23.7 V維持穩定。因此本行走驅動系統之控制器、直流馬達與減速傳動機構之配置可在起步的3 sec後維持電壓電流穩定，性能穩定可靠。

This study has assembled the electric carrier and the carrier can carry the spraying unit. The electric sprayer's moving and spraying performances were tested. The size of the electrically operated self-propelled air-blast spraying machine is 1900*750*1300 mm. The turning radius is 4.8 m. The running speed is between 0.5 to 7.4 km/hr, as the batteries are sufficiently charged. The operating time approximately is 6 hours. The sprayer is operated by the electric power. The essential part is the electrically operated pump. The liquid operating pressure can reach 7 bar. The spraying unit consists of two spraying rods, and each rod has 4 units of Teejet 11001VHXL nozzle. The spraying rods are installed on both side of blower, the flowing rate under 7 bar pressures is 4.8 l/min, the flowing rate of a nozzle is 0.6 l/min. The instant current under the maximum loading of the chassis to move approximately is 82 A. The high electric current maintain approximately 2 sec, then during 1 sec period, the electric current instantaneous drops to below 20 A. Voltage climbs from 0 V to 21.6 V at the first 1 sec, then the high electric voltage is 21.4 V~22.8 V. Finally the voltage jumps to 23.7 V and maintain to be stable. Therefore the design of the sprayer's electric driving system does have stable voltage and current after the first 3 sec. The performance of the sprayer is stable and reliable.
