摘　　要：针对甘蔗收获机输送装置存在输送稳定性差、甘蔗易掉落引起堵塞问题,设计了一种具有良好输送效果和高可靠性的自适应输送装置。采用Adams软件对优化前后的两种输送装置进行了仿真分析。结果表明,优化结构后的输送装置比优化结构前的装置输送时间减少了0.34 s,甘蔗质心水平方向的速度波动时间减少了0.36 s,在驱动拨指链条时间相同的情况下,优化后支架的长度减少了476 mm,减少了增加支架长度在整车布置的难度和导致收获机重心偏高的风险。最后通过仿真分析确定了甘蔗质心位移在竖直方向和质心速度在水平方向具有稳定性,为收获机的稳定作业提供了条件。Focused on problems of poor stability and frequent blockages caused by sugarcane falling during transport in sugarcane harvesters,a self-adaptive conveying device with excellent conveying performance and high reliability was designed.The Adams software was used to perform simulation analyses of the conveying devices before and after structure optimization.The results showed that optimized conveying device reduced the conveying time by 0.34s and decreased the fluctuation time by 0.36s for horizontal velocity of sugarcane mass-centre compared to that before structure optimization.Additionally,under the same driving sprocket chain operation conditions,the length of the optimized support structure was reduced by 476 mm,thereby mitigating the challenges of incorporating longer support structures in the overall harvester layout and reducing the risk of an elevated center of gravity.Finally,the simulation results demonstrated that the vertical displacement of the sugarcane mass centre and horizontal velocity of the sugarcane mass center maintained stability,which provided stable operation condition for sugarcane harvester.
