小型液压挖掘机的构造与性能和一般液压挖掘机基本相同,设计原理与方法也可通用。但是,小型机的作业性能和主要特点毕竟有所不同。本文拟就小型液压挖掘机总体设计中有关挖掘性能的改善与发挥问题,作一点粗浅的讨论。一、转斗挖掘时载荷的确定与挖掘性能的改善小型液压挖掘机的工作对象为Ⅲ级以下土壤,工作装置的主要型式为反铲。由于土质均匀松软,多采用转斗挖掘为主,以利提高作业效率,充分利用挖掘能量。为此,设计工作装置时,应在满足工作尺寸的条件下,重点进行
The structure and performance of a small hydraulic excavator is basically the same as that of a general hydraulic excavator, and the design principle and method can also be used universally. However, the operating performance and main features of minicomputers are different after all. This article intends to discuss the improvement and play of excavation performance in the overall design of small hydraulic excavators. First, determine the load when excavating the bucket and improve the performance of excavation Small hydraulic excavators work on the soil below the level III, the main type of work equipment for the backhoe. Due to the uniform and soft soil, most of the buckets are mainly excavated in order to improve operating efficiency and make full use of excavation energy. For this reason, when designing the working device, it should be carried out under the condition of satisfying the working size.
