The existing snow removal, de-icing highways, and other methods are directed at the spacious road to meet small-scale, low-cost, easy to operate, and other requirements. And this is mainly designed to address snow machine should be adapted to the city streets, courtyards, and so it is not very spacious place. This completed the design of major snow of the collection, transmission and delivery, such as throwing the structural design. According to the snow in northern China to the characteristics of dynamic systems use batteries to provide, through the motor pulley and two reducer connected to achieve the power transfer. In the snow in front of the device configuration set to achieve the snow shovel snow for the collection, transportation in and through the snow will affect the cage transported to send throwing device, sent in by throwing snow will be thrown out for. The design of the main structure of the programme demonstrated, the main structural parameters of the analysis and calculations.
