中文摘要 | 坡地果園栽培,果實採收成本佔極大比例,以空氣壓縮機作為動力,以不平衡環振動方法採收梅等,其每公頃成本,以目前之試驗機可以取代至少30人工。不平衡環振動機之採收對梅、柳丁等有效,尤其分二次採收,初次以高頻低振幅預振,再次以低頻高振幅隔兩天振動,採收率提高甚多。在振動採收中,氣壓之控制範圍,以試驗記錄言,各種水果間,因其自然頻率而異,梅以12kg/cm²及16kg/cm²為最有效,而柳丁則以14kg/cm²至18kg/cm²間最為有效。而往復式振動機對需要拉力之果實採收有效,如油茶等機械採收果實之機械損傷率,非常小,僅不及百分之一,多數係碰撞樹枝所引起;如何改進振動機之性能,應是今後研究之課題。 |
英文摘要 | Most of cost in orchard production system is harvesting. It is convenient by using air compressor as a power source and using unbalance roller as shaker to harvesting prune, peach etc. In harvesting prune, it (at least) reduced 30 labors per hectare by using unbalance shaker. It is more effect to use two shaking process, first time, using high frequency and low amplitude shaker preshake the tree. After two days later, using low frequency and high amplitude shaker shakes the tree, The effect air pressure in prune harvesting is between 12kg/cm² and 16kg/cm². Orange harvesting is between 14kg/ and 18kg/cm² The mechanical damage in shaking process is below 1 percentage, most of damage were fruit bumping the branch, How to improve the shaker effect is most important in future study. |
