The snowfall in winter in northern China has a long time, a large amount and a wide range. If the snowfall can not be cleared in time, it will greatly affect the normal life of people in the northern region, and the sudden snowstorm will also cause major security risks and affect social production. For this reason, this paper developed a machine that can realize road snow cleaning and make bricks from snow. In order to design it reasonably, the working performance standard is planned and designed. The motor speed of the compressor unit is 20R / min, the motor power is 1.05kW, and the vehicle speed is 0.17m/s. At the same time, the theoretical analysis and ADAMS simulation analysis of the core snow compaction unit are carried out, and the conclusion is that the device can meet the requirements of travel and cycle, and the compression moment can meet the performance requirements.
