Description

Technical Field

[0001] The utility model relates to a paving machine for highway engineering construction, belonging to the technical field of paving machines. Background Technique

[0002] A highway refers to a public road that can be traveled by automobiles between cities, between urban and rural areas, and between rural areas, which has been accepted and recognized by the transportation department, including the highways that have been built and recognized by the transportation department. During the construction process of highways, a paving machine is required to lay asphalt pavements.

[0003] According to the patent with the publication number CN212925679U, a paving machine for highway engineering construction is disclosed, which relates to the technical field of highway engineering. It includes a vehicle body. A storage bin is installed inside the vehicle body. The upper surface of the storage bin is fixedly communicated with a feed inlet. The upper surface of the storage bin is fixedly connected with a first motor. The output end of the first motor is fixedly connected with a rotating shaft. One end of the rotating shaft far away from the first motor penetrates through the inner top wall of the storage bin and extends into the interior of the storage bin. Five stirring rods arranged in a linear array are fixedly connected to the outer surface of the rotating shaft. One end of each stirring rod far away from the rotating shaft is fixedly connected with a scraper. The design structure of the utility model is reasonable. Through the cooperative design of a heating plate, a first motor, stirring rods and scrapers, the temperature inside the storage bin is increased by setting the heating plate to prevent asphalt from adhering, cooling and hardening on the inner wall of the storage bin. The scrapers and stirring rods are set to scrape off the residual asphalt on the inner side wall of the storage bin, saving energy and reducing asphalt waste. After the above device is used for a long time, dry materials will remain on the scrapers and stirring rods, which will affect the cleaning effect of the scrapers. At this time, it is inconvenient to clean the inside of the device, thus affecting the subsequent use of the device. Content of the Utility Model
