[0002] As an important support for urban development, road maintenance technology has become increasingly important with the acceleration of urbanization and the increase in vehicle traffic. Faced with problems such as road damage and wear, road maintenance technology has achieved efficient repair of damaged roads through the application of new materials and new processes.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN217266867U discloses a road maintenance device, which drives a telescopic rod 1 to move forward or backward by starting a second motor, drives a slider 1 to slide forward or backward, drives a slider 2 to slide in a circular groove, drives a discharge pipe 2 to rotate, drives the discharge pipe to rotate, drives the circle to rotate, and then changes the left and right pouring of asphalt. However, since the device swings the discharge pipe, the discharge point will change continuously, resulting in a very slow speed when the asphalt is paved. Once it is too fast, it is easy to cause insufficient asphalt in some places. In view of this, we propose a road maintenance device. Summary of the invention
