中文摘要 | 為解決臺灣地區移植型蔬菜之穴盤育苗播種問題,本場應用手拉式 葉菜類播種機之播種原理,研究發展出一套簡易式蔬菜育苗播種一貫作業機。 本機械係以水稻育苗播種一貫作業機械為主體,將其排箱機構及播種機構加以 改良,並加裝打孔機構。其他機構如裝土、整平、澆水、覆土等與水稻播種機 之原來機構完全相同,不需要再修改。排箱機構之作用原理,係以輸送帶之動 力,將最底下一層之穴盤向前輸送,而最底下向上算起第二層以上之穴盤,則 靠一片鐵片擋住,停留在原來的位置,當最底下一層穴盤離開後,其上層穴盤 立即掉落至最底下層,如此連續動作,即可順利完成排箱作業。至於打孔機構, 係採用新設計之懸吊式穴盤用打孔器,利用穴盤向前輸送之動力帶動打孔器之 旋轉,而完成連續之打孔作業。本機最重要之播種機構,係採用杓子式之播種 原理,再利用定速馬達,調整播種盤之旋轉速度,以配合穴盤之前進速度,即 可達到精確的播種效果。本機械每小時可播種300箱,播種精確度可達95%以 上,種子落點距離中心點之距離僅0.47公分。 |
英文摘要 | In order to solve the seeding problem of vegetable plug seedling production, a simple type automatic vegetable seeding machine was developed with the application of seeding mechanism of leaf vegetable seeder that previously developed by the station. An automatic machine for rice seedling production, which was commonly used in the rice nursery center, was used as a framework for this automatic system. A hunging type puncturing mechanism was installed on this automatic machine, while the mechanisms of soil filling, soil flatting, watering and soil covering were remained the same. The tray loading mechanism consisted of a piece of iron and several steel sticks. When a pile of trays were placed on the conveyor of the machine, the bottom tray would be pulled ahead by the conveyor belt, while the rest of the trays would remain on the same place. When the bottom tray was pulled away from the pile, its upper tray would drop down on the conveyor belt. As a result, a pile of trays would be pulled ahead individually. The puncturing mechanism was hunged over the conveyor. When the tray was pulled ahead, the edge of the tray would begin to touch the puncturing mechanism and make it rotate. As a result, every cell of the tray would be punctured to become cavities. A scoop type seeding mechanism, which was the most important part of the automatic system, was installed over the conveyor, and its rotation speed was controlled by a speed- controlled motor to match the speed of conveyor. The accuracy of seeding mechanism could reach over 95% at the capacity of 300 trays per hour. The average distance from the seed site to the center of each cell was 0.47 cm. |
