In a world where snow and ice often bring traffic to a standstill, a father-son duo from Haiyang City in Shandong Province has turned their personal struggles into an innovative solution. Song Chunji, a 26-year veteran truck driver, and his son, both high school graduates, have developed a multi-functional "snow-shoveling and sand-spreading vehicle" that not only clears snow but also evenly spreads salt or sand on the road. This invention integrates multiple functions and has been granted a national patent.
The idea was born during a harrowing winter when they were stuck on the Shitai Expressway for over 30 hours due to heavy snowfall. As they watched workers manually throw salt onto the icy road, they realized how inefficient and time-consuming the process was. The sight of people struggling in the cold sparked a thought: what if there was a machine that could do this job more efficiently?
Inspired by their experience, the pair decided to take action. They sold their truck and invested all their savings into research and development. Despite having limited formal education, Song Chunji's lifelong interest in machinery and his background in mechanical repairs helped him conceptualize the design. His son, who had graduated from junior high school, studied engineering drawing to help bring their vision to life.
After nearly a year of testing and refining, they finally created a prototype. Their machine could both shovel snow and spread sand or salt in one go, with adjustable discharge speeds to suit different road conditions. It also featured an anti-slip system to ensure safe operation on icy surfaces.
The success of their invention did not come without challenges. During a test run, the machine malfunctioned due to frozen sand inside the mechanism. This led them to add a clutch device that would automatically stop the system if similar issues arose. Through continuous improvements, the car became increasingly reliable.
Their work has now attracted attention from local authorities and highway departments. Experts believe the technology can significantly reduce the need for manual labor in road maintenance, saving time, resources, and money. With growing market interest, Song Chunji is confident about the future of their invention.
As the snow season approaches again, the father and son remain determined to refine their creation. Their journey, from a simple idea to a patented machine, shows how perseverance and innovation can turn hardship into opportunity.
