摘要：针对马铃薯收获过程中马铃薯与土壤分离效果不理想、输送环节防损减损能力弱、伤薯率较高等问题，结合中国北方（甘肃）地区马铃薯种植农艺，提出一种马铃薯-土壤分离输送装置运动模型。

重点分析了分离输送装置的力学特性及马铃薯运动机理，确定了影响马铃薯与土壤分离效果以及马铃薯损伤的关键因素：分离输送装置倾角ɑ、机具前进速度V_m、拍打轮振幅A、拍打轮频率f，构建RecurDyn-EDEM耦合仿真模型，确定关键因素对土壤分离效率以及马铃薯损伤的影响规律。

借助目标寻优方法，明确了马铃薯-土壤分离评价指标的较优参数组合：分离输送装置倾角为18°、前进速度为4.7 km/h、拍打轮振幅为32.8 mm、拍打轮振动频率为6.0 Hz。

田间试验表明：马铃薯-土壤分离效率较好，马铃薯含有土壤等杂质较少，马铃薯损伤较小，马铃薯-土壤分离效率平均值为96%，损伤率平均值为2%，与仿真结果相比，误差为0.47%和0.30%，满足马铃薯收获作业质量要求。

Abstract: To address issues such as suboptimal separation of potatoes from soil during harvest, weak damage prevention and reduction capabilities in the transport process, and high damage rates, a  potato-soil-transport device motion  model  was proposed based on potato farming practices in northern China (Gansu). The mechanical properties of the separation  and transport device and the movement mechanism of the potatoes were analyzed, identifying key factors affecting the separation efficiency of potatoes from soil and potato damage: separation transport device inclination angle (ɑ), machine forward speed (V_m),  paddle wheel amplitude (A), and paddle wheel frequency  (ƒ). A coupled RecurDyn-EDEM simulation model was constructed to determine the impact of key factors on soil separation efficiency and potato damage. Using an optimization method, the optimal parameter combination for evaluating potato-soil separation was determined: separation transport device inclination angle of 18°, machine forward speed of 4.7 km/h, paddle wheel amplitude of 32.8 mm, and paddle wheel frequency of 6.0 Hz. Field tests showed that the potato-soil separation efficiency was good, with potatoes containing minimal soil and other impurities and experiencing minimal damage. The average potato-soil separation efficiency was 96%, and the average potato damage rate was 2%. Compared to the simulation results, the errors were 0.47% and 0.3%, respectively, meeting the quality requirements for potato harvesting operations.
