應用於無人機之粒狀肥料撒佈機構開發

Abstract

世界上的人口不斷地在增加，加上飲食習慣的改變，糧食的需求只增不減。現代化的農業技術，須依靠科技的研發創新。機械化是解決目前農業缺工的一個較有效率的方向，針對較大範圍的農地，若能以機械取代傳統人力，不僅在效率上有所提升，施藥施肥也能更為精準、更科學化。較早期的轉盤式有機肥料撒佈機，撒佈的寬度會受到撒佈速度的影響，有其待改善的部分，撒佈不均是其一大劣勢。本研究開發一個可應用在無人機上的肥料撒佈機構，以有別於上述傳統之離心轉盤式，而嘗試以螺旋進行粒肥的輸送，再以直落式的機構做肥料的撒佈，在實驗的結果呈現，每小時輸送量最高可達63.79公斤/小時。

The world’s population is constantly increasing, and with the change in eating habits, the demand for food has only increased. Modern agricultural technology must rely on science and technology. Mechanization is a efficient solution to the current shortage of farming land. For a large range of farming land, if the traditional manpower can be replaced by machinery, not only the efficiency will be improved, but also the application of fertilizer can be more precise and scientific. In the previous developed fertilizer spreaders, the width of the spread was affected by the speed, and that was one of the disadvantages. This research develops a fertilizer spreading mechanism that can be applied to drones in the future. Instead of the spinning mechanism, we try to use screw to transport the granular fertilizer, and then spread it with a straight-down mechanism. The results of the experiment show that the maximum amount of delivery per hour can reach 63.79 kg/hr.
