Optimization and Testing of the Loading Height of the Sweet Potato Harvester
In order to optimize the loading and harvesting height of sweet potato harvesters,this study delved into the damage incurred under mechanical collisions,particularly focusing on the"Suyu 8"model.Through finite element anal-ysis,the collision stress distribution of sweet potatoes at different heights was determined.Additionally,numerical simu-lations initially identified the safe mechanical collision height for sweet potatoes.Sweet potato collision experiments vali-dated these findings,indicating a significant increase in damage when drop heights exceeded 250mm,characterized by distinct dark brown patches.Establishing a maximum height of 250mm for loading sweet potato harvesters provides cruci-al guidance for ensuring safety during the transportation process.
