受動的ハンドリングを使用したホウレンソウ自動収穫機用根切り刃と土壌間に生じる相互作用に関する研究

抄録

Agricultural workers have required automatic harvesters due to aging of the Japanese people recently. Spinach is one of the difficult vegetables to harvest automatically. Therefore, Shinshu University proposed a harvesting method called "passive handling". The previous works revealed that the difference in root cutting blade path resulted in a difference in harvest success rate. The compared paths were horizontal path and arc path, and arc path gave better results. The difference in performance between the two paths has remained unclear. This study clarified the reason why the arc path is good from the viewpoint of the interaction between the root cutting edge and the soil.
