From the development of construction machinery in recent years, the development of excavators is relatively fast, and as one of the main types of construction machinery, the working efficiency of excavators is particularly important. The working efficiency of excavator directly affects the overall progress of the project. Here is how to improve the efficiency of excavator.

　　1. 挖掘机机械性能的注意事项:挖掘机的技术条件对生产率，尤其是发动机的动态性能有很大的影响。当切削齿的耐磨性提高90%~60%时，应更换钝齿;

　　1. Precautions for mechanical performance of excavator: the technical conditions of excavator have a great influence on productivity, especially the dynamic performance of engine. When the wear resistance of cutting teeth is increased by 90% ~ 60%, the blunt teeth should be replaced;

　　2. 挖掘机作业注意事项:挖掘机司机应熟练操作技术，尽量采用复合作业，缩短挖掘机作业周期;

　　2. Precautions for excavator operation: the excavator driver shall be proficient in operation technology and try to adopt composite operation to shorten the operation cycle of the excavator;

　　3.挖掘机工作现场的合理布置:施工前应提前确定挖掘机卸车的行车路线，并不必要的边坡。对于挖掘机的每一条挖掘道路，都应该有一条空的车辆回程道路，以避免进口车辆的相互干扰。为便于自卸车的操作，必须保持良好的操作状态;

　　3. Reasonable arrangement of excavator working site: determine the driving route of excavator unloading in advance before construction, and remove unnecessary slope. For each excavation road of excavator, there should be an empty vehicle return road to avoid mutual interference of imported vehicles. In order to facilitate the operation of dump truck, it is necessary to keep good operation condition;

　　4. 挖掘机工作状态和重型车辆的预防措施:为了满足挖掘机的卸货能力和承载能力,生产能力的要求应当符合挖掘机和卸载能力,应当不可或缺的多斗挖掘机的能力。同时,尝试使用微粉的方法,所以挖掘机充满,紧随其后的是下一个,因为两个自卸卡车停在挖掘机铲斗卸能达到圆弧线,桶满了车辆转向,相反可以充满了另一辆车,以提高装载效率。

　　4. Working state of excavator and preventive measures for heavy vehicles: in order to meet the unloading capacity and bearing capacity of excavator, the production capacity shall meet the requirements of excavator and unloading capacity, and the capacity of multi bucket excavator shall be indispensable. At the same time, try to use the method of fine powder, so the excavator is full, followed by the next one, because two dump trucks stop at the excavator bucket unloading can reach the arc line, the bucket is full of vehicles turning, on the contrary, it can be full of another vehicle to improve the loading efficiency.

　　提高挖掘机的工作效率是保证工程效率的手段之一。挖掘机的日常维护和保养以及战斗方式是提高挖掘机工作效率的途径。

　　Improving the working efficiency of excavator is one of the means to ensure the engineering efficiency. The daily maintenance and fighting mode of excavator is the way to improve the working efficiency of excavator.
