手推式施肥機之研製
Development of the Hand Push Fertilizer Applicator
摘要
本研究設計並研製1臺無動力、四輪、手推式施肥機，可供設施切花、蔬菜作物於畦面施肥作業應用。本機經由前輪接地，帶動卸料裝置迴轉與配出肥料，粒狀及粉狀之有機肥料皆可適用；肥料斗容量54 L，載重為25～30 kg；操作把手位置可調整，供使用者採推或拉2種作業模式應用。施肥機之肥料斗內設有1組擋板，施粒狀肥料時，以擋板承載肥料的重量，可降低卸料裝置阻塞與故障；施粉狀肥料則將擋板掀起，避免肥料發生架橋現象，並以卸料口圓弧狀閘門調節施肥量。經測試結果顯示，當行走速度為0.45 m/sec及卸料閘門選擇第二段，則粉肥施撒量0.45 kg/sec，整體作業效率約為人工撒肥之3.2倍。

The study was to design and develop a manual fertilizer applicator for field culture of flowers and vegetables. This machine bounded grounding through the front wheels to drive the tripper to rotate and dropping the fertilizer into the bed. Powdered or granular type fertilizers are applicabe with this machine. It consists with 4 wheels, a tank with 54-liter volume and 25-30 kg load and adjustable handles. The user can choose either push or pull mode. The machine was composed with fender and roller as to adjust the output amount of fertilizer. When supplies with granular fertilizer, the fender within the fertilizer tank must put down to avoid all the weight on the fertilizer tripper, otherwise caused to obstruction and failure. The opening of the inlet port can be adjusted to control the amount of fertilizer when powdery fertilizer is to be applied, the fender must be lifted up to avoid the occurrence of the bridging of fertilizer. This machine is capable of supplying 0.45 kg powder-fertilizer per second while the forward speed is 0.45 m/sec. The working effeciency is 3.2 time faster than maunal application.
