Abstract

We studied the impacts of soil surface hardness and increased machinery body mass by the harvested crop relative to the fuel efficiency during traveling and driving for head-feeding combine harvesters. The fuel efficiency during traveling and driving increased with softness of the soil, showing a strong correlation with the index of hardness indicated in the Yamanaka model soil penetrometer. The index of hardness realizing fuel efficiency equivalent to traveling on the road was about 23 mm. Based on the fuel efficiency and index of hardness obtained in the testing, a relational expression between the index of hardness and fuel efficiency of the machinery provided for the testing was then figured out, thereby making it possible to correct the fuel efficiency during traveling and driving under any soil conditions. We also confirmed that fuel efficiency during traveling and driving increased with the mass of rough rice in the grain tank. We devised methods of testing and evaluating the fuel efficiency during traveling and driving, by correcting such conditions so as to make a fair comparison among different models. Discipline: Agricultural Engineering Additional key words: fuel efficiency, head-feeding combine harvester, soil moisture weight percentage, soil surface hardness, Yamanaka model soil penetrometer

联合收割机行走与行驶燃油效率评价方法研究

我们研究了土壤表面硬度和收获作物增加的机械质量相对于头馈联合收割机行驶和驾驶时的燃油效率的影响。旅行和驾驶时的燃油效率随土壤柔软度的增加而增加，与Yamanaka模型土壤渗透率的硬度指数有很强的相关性。实现相当于上路行驶的燃油效率的硬度指数约为23 mm。根据试验所得的燃油效率和硬度指标，推导出试验所用机械的硬度指标与燃油效率之间的关系式，从而可以在任何土壤条件下对行驶和驾驶时的燃油效率进行校正。我们还证实，在旅行和驾驶过程中，燃油效率随着谷物罐中粗米的质量而增加。我们设计了在行驶和驾驶过程中测试和评估燃油效率的方法，通过纠正这些条件，以便在不同车型之间进行公平的比较。附加关键词:燃油效率，头馈联合收割机，土壤水分重量百分比，土壤表面硬度，山中模型土壤渗透仪
