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. 【Key words】 Snow—Cleaning Cutting Cracking Road surface 共 2 頁(yè) 第 2 頁(yè)
