摘要: The purpose of this research is to develop a semi-automatic two-row seedling transplanter for vegetablegrowers to transplant nursery seedlings. This machineis driven by a 6 ps / 2000 rpm gasoline engine with atransmission box which consist of 2 forward and 1reverse shifts. The row spacing is fixed as 40 cm andthe planting distance is adjustable as 52、46 or 40 cm.Seven seedling trays could be carried each time. Themechanism of automatic leveling scraper is attachedto control planting depth automatically. When beingoperated in the field, the transplanter follows theridge edges with front wheels as an automatic guilder.The operator therefore, may concentrate on droppingseedlings into the cups of roulette. Seedlings aretransferred to the bill type dibblers and planted intothe soil. One operator with one roulette for two- rowtransplantation is the distinction of this machine.This special feature makes the machine lower laborrequirement. The field experimental results of cabbageseedling transplanting showed the performance of thistransplanter as follows :the miss-planted ratio is2.4%, over inclined 0.4%,damaged seedling 0%, plantingdepth 99.6% and true planting space 100% when 0.33m/sec forward speed. The field capacity of the machineis about 0.11 ha/hr,which is 11 times of that by labortransplanting. Comparing with the cost of labor trans- planting, 62.9% of labor expense may be saved if thistransplanter is employed.
研究設計並試製一台手扶式半自動雙行蔬菜移植機,可提供給農友移 植蔬菜穴盤苗之用。該機配置 6ps/2000rpm汽油引擎,具前進二速、後退 一速選擇;種植行距固定為40cm,株距則有52、46及40cm 三段調整;貯 苗架可同時放置7盤穴盤苗,並藉畦面整平兼畦高自動追蹤之裝置可全自 動控制種植深度。作業時二前輪依循畦形導引自行前進,操作者僅須將菜 苗投入盛苗轉盤之待植苗杯內,即可由移植機的鴨嘴杯種植器定植於畦面 上並覆土。該機最大特色是僅單人即可作業,且一個盛苗轉盤供一畦兩行 種植,較傳統每種植一行需一個人工與一個供苗轉盤的作業方式,更為進 步與省工。田間測試結果顯示:當行進速度0.33m/sec、株距46cm 進行甘 藍穴盤苗移植作業時,缺株率2.4%、倒伏率0.4%、傷苗率0%,種植深度與 實際株距範圍之合格率分別為99.6%和100%,且作業能力為0.11ha/hr,較 人工移植快達11倍,並節省62.9%的工作成本。
