摘 要
推土機(jī)推鏟貨物的作業(yè)是通過(guò)工作裝置的運(yùn)動(dòng)實(shí)現(xiàn)的。推土機(jī)的工作裝置由鏟斗，支撐臂、連桿及液壓系統(tǒng)等組成。鏟斗以推鏟物料；支撐臂和支撐臂油缸的作用是提升鏟斗并使之與車架連接；轉(zhuǎn)斗油缸通過(guò)支撐板，連桿使鏟斗轉(zhuǎn)動(dòng)。支撐臂的升降和鏟斗的轉(zhuǎn)動(dòng)采用液壓操作。
先對(duì)推土機(jī)的發(fā)展概況幾設(shè)計(jì)的指導(dǎo)思想、特點(diǎn)、任務(wù)進(jìn)行概述，然后確定方案，在技術(shù)設(shè)計(jì)部分羅列了推土機(jī)的主要技術(shù)性能和參數(shù)，進(jìn)行了牽引特性計(jì)算，工作裝置設(shè)計(jì)。工作裝置設(shè)計(jì)中有工作裝置運(yùn)動(dòng)分析，對(duì)鏟斗、支撐臂、連桿機(jī)構(gòu)進(jìn)行設(shè)計(jì)等幾部分組成。
在工藝設(shè)計(jì)中敘述了工藝工程。應(yīng)用程序計(jì)算了受力分析。總之，整個(gè)設(shè)計(jì)是有序地完成的。

Abstract
Bulldozers shoveling cargo operation is accomplished by movement of working device. Of bulldozer working device by the bucket, bracket, connecting rod and hydraulic system, etc. Bucket to push shovel material; Bracket and the bracket is to improve the action of oil cylinder bucket and connected to the frame; Turning cylinder through the support plate, connecting rod to rotate the bucket. The rise and fall of bracket and the rotation of the bucket adopts hydraulic operation.
General situation of the development of bulldozer first several design guiding principle, characteristics and tasks are summarized, and then determine the scheme, the technical design part listed the main technical performance and parameters of bulldozer, the traction calculation, working device design. Motion analysis device has a job in the design of device, the bucket, bracket, linkage design, etc.
In the process described in the design of process engineering. Application to calculate the stress analysis. In a word, the whole design is done in an orderly fashion.
Key words: bulldozer, Working device; Intensity; The hydraulic system ...
