單一懸吊唇槽鋼軌道自走式噴霧裝置開發－行走及液體輸送性能試驗
The Development and Testing of Mono-rail Self-propeller Sprayer-The Performance of the Carrier Movement and Liquid Transpotaion
摘要
此研究完成單一懸吊唇槽鋼軌道自走式噴霧裝置，可利用移動噴霧架施用霧粒於標的物上，噴霧架的動力來自於鋼索及絞盤驅動組件。本裝置可以應用於溫室花卉病蟲害防治及育苗噴水灌溉，具有人工手動操作及連線多棟自動操作二種作業方式。此實驗裝置已進行在1.2公頃試驗田區上已建立的17棟玫瑰溫室執行病蟲害防治及噴水施液肥作業。噴架行走速率在0.7至4.3 km/hr之間，輸送藥液主軟管由懸吊滑輪承載，隨噴架移動而伸張或集結。此一負荷對噴架之速率變化差異在1%以下，影響很小。當幫浦壓力25kg/cm^2定壓下，每棟噴霧架裝置20只單孔扇型噴頭，單位面積施噴量受噴霧架之行進速率控制，用量介於3.5 lt/a至21 lt/a範圍，主軟管內徑10 mm，管長68 m，噴架下方噴桿處壓力13.4 kg/cm^2，壓力損失率46%，顯示藥液輸送管路有改進之必要。藥液附著度試驗結果葉上表面有93%樣本數達附著度70%以上，不同畦溝及不同高度有些微之差異。葉下表面僅53%樣本數達附著度40%以上，上層與下層之差異較大。

Mono-rail spraying equipments were developed for mist spraying in nursery and pesticide application in protected culture. The equipment could spray droplets to target by moving spray carrier that driven by a wire loop and winch set. The prototype equipment could be operated by manual or automatic control. The field tests had been executed in 17 floral greenhouses (total area 1.2 ha). The spraying carrier indicated good moving performance. The speed range was between 0.7km/hr and 4.3km/hr. The spraying quantity can be changed from 3.5 lt/a to 21 lt/a depending on the moving speed of spraying carrier at the 25 kg/cm^2 pump pressure. The pressure in spraying pipes is 13.4 kg/cm^2. The pressure loss rate was 46% with main hose that has 10mm inner diameter and 68m length. The adherent percentage was above 70% for the 93% sample of upper leaf surface affecting by the heights. The adherent percentage was only 40% for the 53% sample of lower leaf surface. The difference was significant between the different surface.
