| 摘 要： | 针对马铃薯收获机收获作业提出的更高要求，对马铃薯收获机输送链进行仿真分析和参数优化。通过分析，马铃薯横切面半径越大，在输送过程中越不稳定，在不发生漏薯的情况下，增加相邻栅条的距离可以提高马铃薯输送的稳定性。基于ADAMS对输送链不同水平夹角下的马铃薯滚动进行分析，马铃薯滚落速度变化与输送链倾角有关，在倾角≤30°时，马铃薯滚落速度能够达到稳定状态而不会继续增加，为马铃薯输送链的设计提供依据。建立马铃薯薯土分离效果与输送装置参数的关系，通过分析和试验的方式设计了主从驱动轮的中心距h为1 500 mm、输送链倾角β为25°、提升高度为634 mm的输送链，能够实现马铃薯的输送分离作业。

| Abstract: | In response to higher requirements of potato harvester harvesting operations，simulation analysis and parameter optimization of potato harvester conveyor chain were carried out.Through analysis，the larger the cross-sectional radius of potato was，the more unstable it would be during transportation process.Increasing distance between adjacent grids could improve stability of potato transportation without leakage of potatoes.Based on ADAMS，potato rolling under different horizontal angles of conveyor chain was analyzed.Speed change of potato rolls was related to inclination of conveyor chain.When it did not exceed 30°，the potato roll speed could reach a stable state without continuing to increase.It could provide a basis for design of potato conveyor chain.Relationship between potato soil separation effect and conveyor device parameters was established.Through analysis and test，a conveyor chain with a center distance h of 1 500 mm，a conveyor chain inclination angle of 25° and a lifting height of 634 mm was designed.It could realize transportation and separation of potatoes. |
