摘要
目前我国韭菜收割作业多采用人工方式,效率低且成本高。为解决这一问题,设计了一种履带型自走式韭菜收割机,该机整体尺寸较小,结构紧凑,采用直流电机驱动,可实现原地转向。同时,装备了传感器系统,具备自主避障功能,并可根据实际需要随时调整割刀高度。田间试验表明,该设备加速流畅,非工作期间稳定行驶速度可达4 m/s,工作期间平均收割速度可达0.18 m/s,能很好地完成韭菜收割工作并通过夹持机构向后完成韭菜传输,符合设计预期及机械化收割相关标准。该收割机有效地提高了收割效率,降低了人工成本,为设计研发类似的小型收割机构提供了一定的参考价值。
At present,Chinese chives harvesting operations are mostly manual,low efficiency and high cost.In order to solve this problem,this study designs a crawler-type and self-propelled Chinese chives harvester,which had a small overall size,compact structure,and was driven by a DC motor to realize in-situ steering.At the same time,it was equipped with a sensor system with autonomous obstacle avoidance function,and the height of the cutting knife could be adjust at any time according to the actual needs.Field tests showed that the equipment accelerates smoothly,and the stable driving speed during non-working period can reach 4 m∕s,and the average harvesting speed during working period could reach 0.18 m∕s,which could complete the Chinese chives harvesting work well,and complete the Chinese chives backward transmission through the clamping mechanism,which was in line with the design expectations and the relevant standards of mechanized harvesting.The harvester improved the harvesting efficiency,reduced labor costs,for the design and development of similar small-scale harvesting institutions to provide a certain reference value.
