[0002] In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages), and provide paid or free public products and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls into the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (part outside the red line), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all fall into the category of municipal engineering.

[0003] The invention with application number CN202111182955.X discloses a paved asphalt paving device for municipal engineering, including a vehicle plate, two handlebars are fixedly connected to the left side of the top of the vehicle plate, four wheels are arranged at the bottom of the vehicle plate, an inclined plate is fixedly connected to the right side of the vehicle plate, vertical plates are fixedly connected to the front and rear sides of the inclined plate, a pressure roller is rotatably connected to the first rotating shaft between the opposite sides of the two vertical plates, and a cleaning mechanism is arranged between the pressure roller and the vertical plate; the cleaning mechanism includes a chute that runs through the front sides of the two vertical plates, a sliding rod is arranged at the bottom of the inclined plate and at the top of the pressure roller, and the left and right ends of the sliding rod both run through the chute and extend to the inside of the chute, and the present invention relates to the field of municipal engineering technology. The paved asphalt paving device for municipal engineering, through the arrangement of the cleaning mechanism, makes it easy to remove the asphalt adhering to the pressure roller, saving a lot of time and physical strength, and the cleaning efficiency is very high, no additional tools are needed for cleaning, and it is very practical.

[0004] However, the asphalt paving device in the above patent has the following problems in actual use:
