摘要
20世紀(jì)八九十年代以來(lái)，小型工程機(jī)械在市政工程、交通等施工中發(fā)揮了較
大優(yōu)勢(shì)并得以迅速發(fā)展。小型挖掘機(jī)在這些工程中為節(jié)省人力、物力做出了較大
貢獻(xiàn)，滿足了城市各種作業(yè)要求，在城市狹窄的工作空間內(nèi)能夠最大限度地發(fā)揮
其生產(chǎn)能力，逐步成為城市施工中具有代表性的施工機(jī)械。
小型挖掘機(jī)體積小、機(jī)動(dòng)靈活，非常適用于城鎮(zhèn)的各種管道開(kāi)挖、基礎(chǔ)施工 、
公用事業(yè)以及房屋維修等作業(yè)。小型挖掘機(jī)緊湊的體積、特殊的設(shè)計(jì)使其能夠在
大型挖掘機(jī)無(wú)法施工的環(huán)境中進(jìn)行作業(yè)。
本次的主要目的是熟悉機(jī)械設(shè)計(jì)的一般過(guò)程，提高理論知識(shí)和實(shí)踐知識(shí)的綜
合運(yùn)用能力。挖掘機(jī)是一種重要的工程機(jī)械，它的廣泛應(yīng)用對(duì)于減輕勞動(dòng)量，保
證工程質(zhì)量，加快工程進(jìn)度，提高勞動(dòng)生產(chǎn)率起了巨大的作用。反鏟工作裝置由
動(dòng)臂，斗桿，動(dòng)臂液壓缸，斗桿液壓缸和鏟斗液壓缸組成。

Abstract
Since the 20th century , sma ll and med ium-sized construction machiner y in the
municipa l engineer ing, transportation and other construction pla y a large and rapid
development . Mini-exca vator which is in these projects in ordered to save ma npower
and materia led to make a greater contribution for the city to meet various operationa l
requirements, in a city within a narrow working space to ma ximize its production
capacity to gradua lly become the city with the construction of construction machinery.
Small excavators have sma ll size and flexible, It is very applicable to the various
channels of urban excavation, foundation construction, utilities and housing
ma intena nce operation. The size of sma ll compact excavators, specia l design to enable
it to in large excavators can not carry out construction work environment.
The ma in purpose of the design project for graduation is to be familia r with the
genera l process of mecha nical design and to enhance the comprehensive capacity of
using theoretica l and practica l knowledge. Excavator is an important engineer ing
machinery. Its wide applica tion plays a tremendous role to reducs the volume of labor
and to ensurs project quality and to accelera ts progress and to increas es productivity.
Backhoe working devices is made up of a moving arm and a fighting pole and shovel
and a hydraulic tank of moving arm and a hydraulic tank of fighting pole and a
hydraulic tank of shovel.
Key words：Sma ll hydraulic excavator Hydraulic Working device Design
