中文摘要 | 設計一間距變化式分級機構,由輥子鏈、分級板、導板所組成。分級板上端連結 於輥子鏈上並隨之移動,下端則靠在導板上滑行。由於導板的傾斜角使分級板之間的間隙隨 著輥子鏈移動而增加,應用此分級原理,果實進入分級機構後隨著分級板向前移動,大小不 同的果實分別在適當位置通過間隙落於各級收集盒中,完成分級作業。 自南投水里鄉取樣調查梅子粒徑分佈,結果平均短橫徑26.79mm,長橫徑28.73mm, 縱徑30.12mm,重13.39g;依據以上資料決定分級機構參數,完成梅子大小分級機構雛型 機。經試驗後,以短橫徑與直量的關係式推算求得分級指標如後:分兩級時,分級效率為88%, 分級純度88%;升三級時,分級效率約為74%,分級純度76%。 |
英文摘要 | The purpose of this study is to design a grading mechanism which is constructed by roller chain, sizing plates and guide plate. Sizing plates are linked to roller chain, the other side is sliding against guide plate. The opening between sizing plates is increasing as roller chain moving. Fruits enter grading mechanism and lie on gaps between sizing plates. When roller chain moves to proper position at which the opening is large enough, then smaller fruits will drop into bin through gap between sizing plates. Later, the larger fruits drop into different bin, and grading procedure is accomplished. The main dimensions of samples of plum from Shuili town in Nantou county were measured. Averaged short-diameter is 26.79mm, long-diameter is 28.73mm, length is 30.12mm and weight is 13.9g. According to the investigation, we decide main parameters of grading mechanism. Using the relationship between short-diameter and weight, we calculate the sorting indices after grading experiments, and find sorting efficiency is 88% and sorting purity is 88%, when two-grades is achieved; sorting efficiency is 74% and sorting purity is 76%, when three-grades is achieved. |
