Analysis and Experiment of Potato Pieces Motion in Side-mounted Potato Combine Harvester
摘要
Abstract
Aiming at the problems of high breakage rate and low harvesting efficiency in the harvesting process of the side-mounted potato combine harvester in China,the conveying system of the designed side-mounted potato combine har-vester was analyzed and calculated,and the guide roller was innovatively added to prevent the potatoes in the conveying device.The speed,energy change and damage situation on the machine were analyzed,and the key factors affecting the potato injury rate were obtained,and the simulation test and field test were carried out.The angle between the roller and the transverse conveying device is 43.4°,and the linear speed of the transverse conveying device is 1.52m/s.The equiv-alent strain of the potato pieces caused by the guide roller is the smallest.At this time,the potato injury rate is 1.2%,which is significantly lower than that without parameter optimization.The mechanical damage of the side-mounted potato combine harvester meets the requirements of potato harvesting operations.关键词
