小型除雪機(jī)設(shè)計(jì)
[摘要] 我國北方地區(qū)冬季降雪時間長，雪量大，氣溫低，積雪數(shù)日經(jīng)車輛、行人碾壓而被壓實(shí)。路面上壓實(shí)冰雪的清除問題關(guān)系到社會生產(chǎn)、人民生活、交通安全、環(huán)境保護(hù)等多個方面。目前國內(nèi)外對壓實(shí)冰雪的清除還缺少行之有效的辦法。本文結(jié)合我國北方地區(qū)降雪后的特點(diǎn)及我國國情，主要針對路面上被壓實(shí)的冰雪研究了路面冰雪清除機(jī)械。
本文提出了對路面壓實(shí)冰雪進(jìn)行擠壓、切削、破碎的技術(shù)原理。根據(jù)這一原理確定了路面冰雪清除機(jī)械基本方案并分析了其工作機(jī)理。提出利用裝載機(jī)為動力機(jī)，只需更換上清除冰雪裝置，實(shí)現(xiàn)了一機(jī)多用。研究了傳動系統(tǒng)各部件的匹配以及冰雪清除裝置與整機(jī)的匹配，進(jìn)行了匹配計(jì)算和整機(jī)牽引性能分析。根據(jù)整機(jī)方案及相關(guān)條件確定了清除冰雪裝置中關(guān)鍵部件碾壓滾的構(gòu)造、重量和有關(guān)技術(shù)參數(shù)；分析研究了碾壓滾上刀齒的結(jié)構(gòu)和關(guān)鍵幾何參數(shù)，確定了刀齒在碾壓滾上的排列方式、數(shù)量和間距，并根據(jù)冰雪的物理機(jī)械性質(zhì)計(jì)算了刀齒切削力。

Abstract
In the north of China, when the winter comes, the time for snowing is very long and the air temperature is low. The snow will become very hard after pressed by vehicles and foot passengers. So at this time snow cleaning became very important to people’s living, traffic safety and so on. At present, there is still no effective method for cleaning the pressed snow in the world. In this paper, according to the situation of our country, the author did some researches on the snow-cleaning machine which used to clean the pressed snow on the road surface.
In this paper, the author put forward a technical theory about use the method of pressing, cutting and cracking to clean the pressed snow. According to this theory, the author brought forward a project for snow-cleaning machine and analyzed its working principle. Here used the loader as the mover, when it was time to clean snow we just needed to replace the bucket with the snow-cleaning equipments. The matching calculation of components’ of transmission system and the whole machine were studied and analyzed. According to the project, we could decide the structure, weight and related technical parameters of the idler wheel. At the same time, the paper also analyzed the structure and geometry parameters of the idler wheel, gave a method about how to arrange the cutters and how to decide the reasonable amount of the cutters, how to calculate the cutter’s cutting force base on the snow’s physical and mechanical characters.
