农用液压挖掘机反铲斗的斗齿力变化规律、最大值发生的位置是单斗液压挖掘机的重要性能参数,是挖掘能力的主要标志。 一、铲斗挖掘时斗齿力设计曲线与试验曲线的研究 铲斗挖掘时,设计斗齿力的大小主要取决于机组稳定性、工作装置的平衡能力,液压系 The change rule of the bucket tooth force and the position where the maximum value occurs in the backhoe bucket of the agricultural hydraulic excavator are the important performance parameters of the single bucket hydraulic excavator and are the main signs of the excavation ability. 1. Research on the design curve and test curve of bucket tooth strength during bucket excavation When the bucket is excavated, the size of the design bucket tooth strength mainly depends on the stability of the unit and the balance of the working device.
