摘要
1割切角兩片皆爲平滑又時不能大於57°。固定刄具有鋸齒，活動刄平滑時其最大角度不能超過62°。兩片皆爲鋸齒刄則不能大於67°。 2無論其刀刄形狀平滑或鋸齒割切角在40°左右所需能量最小。 3割切速度超過180in/Sec時，割斷所需之能量增加，且速度增陝則割斷之後稻草基部雜亂。 4具有鋸齒之刀刄割斷稻株所需之能量較平滑刀刄大，如圖七。 5稻株輸送裝置以側（或旁）送式構造較簡單，對於小型收穫機相當理想。 6撥稻桿以利用兩個旋轉方向相反之星狀輪將水稻拉往機身較理想，惟構造複雜。

1. Cutting angle should not operate greater than 57° if both stationary blade and moving blade are flat and smooth. Cutting angle should not excess 62° if stationary blade is notched but moving blade is flat and smooth. Cutting angle snould not excess 67° if both stationary blade and moving blade are notched. 2. Whether the cutting blade is smooth or not the cutting angle about 40° needs the least energy. 3. If cutting speed excesses 180 in/sec, the quicker the bar reciprocated the more the energy of cutting is required, and the straw root are confused. 4. A notched blade needs more energy in straw cutting than a smooth blade does. 5. It is much better to use side delivering in the straw conveying system than any othor delivering methods and this kind of construction is more convenient on a small harvester. 6. It is better to use two reels rotating contrarily in order to draw the straw toward the cutting bar.
