中文摘要 | 狼尾草青割收穫機在研製並經田間試驗達作業功能要求後,移置室內,模擬狼尾草田間生育狀態,於變數可控制之條件上,予以試驗,以期該機商品化後搭載合適之驅動機,其結果如下: 1.該機起動扭力高達8.063kgf-m(20.06 ps),空轉負載扭力為2.199kgf-m(5.47 ps)。 2.作業速度以0.90~1.12m/s (3.0~4.0 km/hr)有較穩定與趨中之細斷長度;割後基部整齊度全在±5mm內;基部切口撕裂率1.3﹪最少。 3.狼尾草物性影響作業扭力顯著。作業總動力需求,經迴歸分析結果,單位重量耗用扭力為1.3475kgf-m/kg,由單位長重量所推測之單位長度扭力,其方程式為: Tu=1.91772*Wu-0.06901 4.狼尾草青割收穫作業所耗用動力的預估公式為: Nt=N*Tu*AH*AN/716 |
英文摘要 | By a series of field tests that revealed the capabilities of Napier Forage Harvester for Green Feeding, the machine was removed in the room for model testing. We limit it in one condition that the variable factors can be controlled. The results are as following: 1.The testified starting torque is 8.06 kgf-m (20.06 ps), when in the idle condition is 2.199 kgf-m (5.47 ps). 2.When the working velocity is 0.90~1.12 m/s (3.0~4.0 km/hr),the chopping length are more stable; the homogeneity after cutting of the basal parts of Napier Grass is among ±5 mm totally; and breaking rate is 1.3﹪. 3.The physical properties affect the working torque obviously. The harvesting torque by using multiply regression analysis is 1.3475 kgf-m per kilogram. We infer the torque per meter form the weight per meter are: Tu=1.91772*Wu-0.06901 4.The interable formula of the power exhausted of Napier Forage Harvester is: Nt=N*Tu*AH*AN/716. |
