摘要
本文设计是一种挖掘装载机的挖掘装置,在为工业、民用上有特殊用途的挖掘装载机,它可以用于煤矿井下狭小空间清理、装载、运输等工作,也可用于冶金、矿山、隧道建设等场合的挖掘装载工作。在本设计中,通过对国内外现有技术的了解和分析,利用任务书上所给定的挖掘机铲斗额定装载载荷,先计算出铲斗的斗容,而后选用标准容量铲斗,根据所选出的标准铲斗,算出挖掘机的最大铲取阻力、最大卸载高度、最小卸载距离等一些设计必需用到的量。通过对工作机构上九个铰接点位置的确定来设计出动臂模型及动臂上各点的受力,然后计算出举臂油缸和转斗油缸的内径、活塞杆的杆径,选出标准的液压缸。
运用CAD制图。

Abstract
In this paper, the design is a mini-excavators, as for the industry, there are special-purpose civilian loading machinery, it can be used in underground coal mines to clear a narrow space, loading, transport, etc., can also be used for metallurgy, mining, occasions, such as tunnel construction excavation work this design, both at home and abroad through the understanding of existing technology and analysis, the use of task books given by the excavator bucket load rated load, calculate the first bucket of the bucket capacity, and then choose the standard size of the bucket, elected in accordance with standard bucket, to calculate the largest excavator shovel access resistance, the maximum unloading height, minimum distance, such as unloading the design used in the volume necessary. Through the work of nine institutions to determine the location of hinge points out to design the model and the moving arm arm stress points, and then calculate the fuel tank and to fight the diameter of the fuel tank, the rod diameter rod, the election a standard hydraulic cylinders.
Keywords: bucket, hydraulic cylinder, boom, excavator
