清雪车设计

摘要

我国北方冬季时间长降雪量大，如果不及时清除积雪，将严重影响交通安全，给人们日常生活带来诸多不便。多功能清雪车的研制，有重要的实用价值，对国民经济的发展有重要意义。

清雪车清雪能力的强弱很大程度上取决于清雪装置性能的好坏，所以深入研究清雪装置的结构和性能是非常必要的。用于清除浮雪的装置主要为螺旋集雪装置，一般与高速旋转的风机、抛雪筒联合使用。雪被螺旋集雪装置收集并通过风机旋转带动从抛雪筒抛到路边或者运雪车上，节省了收集雪的时间，清雪效率较高。

本文基于对积雪的物理机械特性分析，提出机械式除雪的几种方案，并针对离心扬雪式除雪机构，分别对除雪机构中的螺旋集雪机构和离心排雪机构的工作原理进行分析，在理论分析的基础上得出结论。

Abstract

Winter lasts for a long time in the cold areas of northern China.A great amount of snow falls there each year.Therefore,if the accumulated snow cann ot be removed and cleaned in time,it will severely affect the safety of the transportation and bring out a lot of inconveniences to the people’s daily life.The manufacture of the multi-functional snow-moving machine will be found of important and practical value in forming good transportation and hygiene environment in winter.

The snow clearing capacity of the snow-remover depends on the properties of snow clearing device,so it is necessary to study the structure and properties of snow clearing device deeply. The device mainly used for clearing floating snow is spiral snow collection,which is generally used with highspeed rotating fan and snow throwing cylinder.Snow is collected by spiral snow collection and threw to roadside or snow truck through snow throwing cylinder driven by rotating fan,which can save time,and the efficiency is high.

The thesis works out a basic project on the multifunctional now-moving machine through the study of the physics mechanical haracters of the snow.It lays great emphasis on the study of Community throwing snow machine.

Keywords: Snow-Remove Machine;Helix-Collect snow;Community throwing snow.
