中文摘要 | 本研究建立一套室內真空播種測試實驗設備,以靜態吸附實驗,量測並分析相關因子對真空播種效能之影響。由對清江白菜、蘿蔔、芫荽、芥藍與小白菜等五種種子樣子之測試結果可知:種子質量、長短軸徑、周長以及靜置截面積,都是靜態有效作業真空值的顯著相關因子,其中質量最為顯著。圓度的相關性則較不顯著。大孔徑之吸孔可降低作業真空度需求,但在實際作業時卻易造成複粒的現象。因此作業真空度之選用是否得宜,將直接影響真空播種機之作業性能。 |
英文摘要 | In this study, an indoor experimental device for vacuum seeding test was established. Five kinds of seeds, i.e. Chinese mustard, Radish, Coriander, Chinese Kale, and Pak-Choi, were investigated. In stationary suction experiments, we used the device to measure and analyze the effects of physical and geometric factors of seeds on the effectiveness of vacuum seeding. The results showed that, the effective operation vacuum was influenced by the mass, axes lengths, perimeter and cross-sectional area of the seed; the mass was the most significant. The roundness was not a significant factor. The vacuum could be relaxed with a larger pick-up orifices, but several seeds might be picked up at the same time. It was concluded that the vacuum could directly affect the performance of the drilling operation. |
