摘　　要：为降低龙门式枸杞采收机在收集过程时枸杞的损伤率,以采收机收集系统为研究对象,通过分析采收过程和输过程中枸杞的运动轨迹,发现枸杞采收过程存在8个关键阶段。结果表明,在振动采摘阶段枸杞与枝条之间发生多次机械碰撞,枸杞损伤率较高,且得出采摘条材质是降低此阶段机械损伤率的关键因素。由于在收集阶段枸杞与输送带之间存在摩擦和翻滚现象,通过对枸杞输送过程中运动学分析发现,输送带以速度0.5 m/s、倾斜角度36°、落果高度14 mm运行时,枸杞损伤率为最低(3.2%),且试验也发现在田间性能条件下采收机采收效果最佳,研究可为小型浆果输送装置优化提供参考。In order to reduce the damage rate of wolfberry during the collection process of the gantry wolfberry harvester,this study takes the harvester collection system as the research object.By analyzing the trajectory of wolfberry during the harvesting process and the transportation process,it is found that there are eight key stages in the wolfberry harvesting process.The results showed that multiple mechanical collisions occurred between wolfberry and branches during the vibration picking stage,and the damage rate of wolfberry was higher.It was concluded that the material of the picking strip was the key factor to reduce the mechanical damage rate at this stage.Secondly,due to the friction and tumbling phenomenon between the wolfberry and the conveyor belt during the collection stage,through the kinematics analysis of the wolfberry conveying process,it was found that when the conveyor belt was operated at a speed of 0.5 m/s,an inclination angle of 36°,and a fruit drop height of 14 mm,the wolfberry damage rate was the lowest(3.2%),and the field performance test also found that the harvester harvesting effect was the best under this condition.This study can provide reference for the optimization of small berry conveying device.
