摘  要

掃雪機(jī)的問(wèn)世，讓人們?cè)谏钪袦p少了很多麻煩。本文在分析了國(guó)內(nèi)外多種掃雪機(jī)的發(fā)展現(xiàn)狀之后提出，主要運(yùn)用范圍是大型除雪設(shè)備所不能觸及到的路面。結(jié)合路面的寬窄，積雪的厚度等因素，設(shè)計(jì)了一種小型的路面掃雪機(jī)。本設(shè)計(jì)在對(duì)掃雪機(jī)的工作原理進(jìn)行分析的基礎(chǔ)上，通過(guò)計(jì)算確定機(jī)械傳動(dòng)機(jī)構(gòu)及動(dòng)力裝置，然后進(jìn)行控制系統(tǒng)設(shè)計(jì)，把控制和機(jī)械有機(jī)結(jié)合。

本設(shè)計(jì)運(yùn)用三維繪圖軟件創(chuàng)建了掃雪機(jī)各零部件三維模型，進(jìn)行整體的三維裝配，展現(xiàn)其整體的造型效果，繪制部分二維零件圖及裝配圖，完成了基于單片機(jī)的微機(jī)控制電氣原理圖。

ABSTRACT

The advent of snowplows has reduced people's troubles in their lives. This paper analyzes the development of many kinds of snowplows at home and abroad.The main application is the surface of the road that the large scale removal equipment cannot reach.Combined with the width of the road and the thickness of the snow, a small road snowplow was designed.This design on the basis of the analysis of the working principle of the snowplow, through the calceolation to determine the mechanical transmission mechanism and power device and then designed the control system to combine the control and machanism in a organic way.

This design using the 3 d drawing software to create a snowplow parts 3 d model, the whole 3 d assembly, show the modelling of its overall effect, the drawing part 2 d part drawing and assembly drawing, completed based on single chip microcomputer control electric schematic diagram.
