中文摘要 | 本研究旨在研製破布子脫粒篩選機,以解決費時費工之破布子摘果粒去果蒂的問題,節省人工,降低生產成本◦已完成破布子脫粒篩選機乙部,主要由單組相對旋轉之縱向斜裝刷桿、挾送裝置、噴水管路、出料斜槽與篩選裝置等組件組成◦經試驗分析最佳化之脫粒作業條件為脫粒轉數107 rpm(線速度0.59 m/s)、進料挾送轉數23 rpm(線速度0.06m/s)、毛刷長度20mm與毛刷交錯長度3 mm,其機械脫粒之作業性能分別為良好率92.7%、損傷率0%、未脫率3.2%與夾斷帶蒂率4.1%;而篩選裝置採輸送柵鏈設計,柵鏈網目為16×16 mm,經測試已符合要求◦整體之機械作業能力達9.1 kg/hr,分別為人工脫粒專業工的14倍與非專業工的5.9倍◦ |
英文摘要 | To solve the time-consuming, labor-intensive problem of detaching fruits from stalks, a snapping and screening machine for Cordia Dichotoma was designed and manufactured to reduce the labor requirement and production cost. The machine was made of a pair of longitudinal brush rollers, a pair of feeding belts, a screening device, a water pipe system and a fruits-collecting chute. A better combination of settings for snapping operation includes a rotating speed of snapping roller at 107 rpm, a rotating speed of feeding pulley at 23 rpm, a brush length of 20 mm, and a brush overlap length of 3 mm. The Operating performance of developed snapping machine was determined to be with an acceptable rate of 92.7%, an unstriped rate of 3.2% and a miscellaneous rate of 4.1%. Attached screening device, manufactured by using a bar-chain conveyor with a mesh size of 16×16 mm, was proved to achieve the design goal. Overall operating capability (9.1 kg/hr) of the snapping and screening machine is about 2.4 (5.9) times as that of a professional (amateur) worker. |
