本文分析了菠菜自动收获机切根刀片在地面下运动时产生的土壤行为。由于菠菜的茎和叶柔软且容易受伤，因此使用自动收割机收割菠菜以生吃是困难的。因此，能够在农民中广泛使用的收割机尚未开发出来。为了克服困难，我们一直在开发不会碰伤菠菜的自动菠菜收割机。切根刀片的轨迹对于实现这种自动收割而不擦伤菠菜是非常重要的，因为切割菠菜根的运动受到刀片挤压并移动进入的土壤的影响。因此，本文采用离散元法（DEM）研究自动收获，阐明了动刀片引起的土壤行为的一些特征，并对动刀片引起的土壤行为进行了艾德。最后，指出并描述了两个重要的特性，即动叶片的速度和动叶片移动的通道场中的土壤体积。
Soil behavior generated by a root-cutting blade moving under the ground of an automatic spinach harvester for spinach for eating raw is analyzed in this paper. It is difficult to harvest spinach for eating raw by using automatic harvester because stems and leaves of spinach are soft and easily bruised. Thus the harvester which can be widely used among farmers has not been developed. To overcome the difficulty, we have been developing the automatic spinach harvester which does not bruise spinach. A trajectory of a root-cutting blade is very important to achieve this automatic harvesting without bruising spinach because the motion of cutting the root of spinach is influenced by soil which the blade presses and moves in. In this paper, accordingly, some characteristics in the behavior of soil caused by the moving blade are clarified by using the distinct element method (DEM) to investigate the automatic harvesting. In conclusion two important characteristics, the velocity of the moving blade and the volume of soil in the passage field the blade moved, are pointed out and described.
