整秆式甘蔗收获机输送调控系统设计与试验

针对甘蔗生长的随机性使收获机喂入量随时变化，易导致整秆式甘蔗收获机输送堵塞或工作效率低下的问题，设计了一种整秆式甘蔗收获机输送调控系统。该系统由动态扭矩传感器、PLC控制系统、液压系统、伺服电机系统组成，通过实时调节输送辊转速与喂入速度使得甘蔗收获机输送能力与喂入量相匹配，减少甘蔗堵塞情况。通过搭建甘蔗收获机试验平台，开展甘蔗输送调控试验。甘蔗输送调控试验结果表明，安装了输送调控系统后，各试验水平下的甘蔗平均输送速度为4.06、3.42、3.04、2.42m/s，相比无调控系统有了明显提升，并且收获机输送能力在喂入量峰值过后恢复到初始值，保证了工作效率；调控试验的平均堵塞率降低到5%，输送调控系统对缓解输送堵塞有显著作用。

Design and Experiment of Conveying Control System for Whole Rod Sugarcane Harvester

Aiming at the randomness of sugarcane growth, which causes the feeding amount of the harvester to vary from large to small, which can easily lead to blockage or low efficiency in the transportation of the whole rod sugarcane harvester, a conveying control system for the whole rod sugarcane harvester was designed. By building a sugarcane harvester experimental platform, based on dynamic torque sensors, PLC control system, hydraulic system and servo motor system, real-time adjustment was made to match the conveying capacity of the sugarcane harvester with the feeding amount, reducing sugarcane blockage. The results of the sugarcane conveying control experiment showed that after installing the conveying control system, the average conveying speeds of sugarcane at each experimental level were 4.06m/s, 3.42m/s, 3.04m/s, and 2.42m/s, which were significantly improved compared with those without the control system. Moreover, the conveying capacity of the harvester (the walking speed of the harvester and the speed of each conveying roller) returned to its initial value after the peak feeding rate, ensuring the efficiency of field harvesting work. The average blockage rate of the regulation experiment was reduced to 5%, and the conveying regulation system had a significant effect on alleviating conveying blockage.
