Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a paver for highway engineering. Background Art

[0002] During the asphalt road construction process, asphalt needs to be laid on the road. The asphalt paving construction process is generally completed by an asphalt paver. The asphalt material is poured into the paver, and then the paver mixes the asphalt material and spreads it on the road. The asphalt material is then preliminarily leveled to complete the asphalt road paving.

[0003] According to a highway construction paver mentioned in the utility model patent with Chinese patent application number 202020671480.5, the highway construction paver can solve the above-mentioned problems of poor material distribution, uneven paving, and inability to adjust the paving width when in use. However, the highway construction paver does not have the function of external cleaning of the paving roller of the paver when in use. The asphalt or mud rolled on the road surface is easy to adhere to the outer surface of the paving roller, resulting in the problem of uneven road paving in the later stage. Therefore, it is necessary to propose a highway engineering paver to solve the above-mentioned problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose of cleaning the outer surface of the paving roller, the utility model provides the following technical solution: a highway engineering paver, comprising a cleaning cover, a first conveying pipe and a second conveying pipe fixedly connected to the top of the cleaning cover, a scraper fixedly installed inside the cleaning cover, a lifting assembly movably installed on the top of the cleaning cover, a paving roller movably installed inside the cleaning cover, and a paver housing installed outside the paving roller;

[0006] The lifting assembly includes a threaded rotating rod, and a threaded rotating rod is movably installed inside the paving machine shell. The external thread of the threaded rotating rod is connected to the first threaded block and the second threaded block. The interiors of the first threaded block and the second threaded block are respectively hingedly connected to the first hinged rod and the second hinged rod. The bottom ends of the first hinged rod and the second hinged rod are hingedly connected to the hinge block, and the bottom of the hinge block is fixedly connected to the cleaning cover.

[0007] Furthermore, a through groove is provided inside the cleaning cover, and a through hole is opened on the inner wall of the cleaning cover, and the through hole is connected with the first conveying pipe and the second conveying pipe through the through groove.

[0008] Furthermore, a first rotating shaft is movably installed inside the paving machine shell, and two groups of first conveyor belts are transmission-connected to the outer surface of the first rotating shaft.

[0009] Furthermore, a second rotating shaft is movably installed inside the other end of the first conveyor belt on the right side, and the second rotating shaft is fixedly connected to the left and right sides of the paving roller.

[0010] Furthermore, a rotating rod is fixedly connected to the right end of the threaded rotating rod, and a second transmission belt is transmission-connected to the outer surface of the rotating rod.

[0011] Furthermore, the size of the cleaning cover is adapted to the paving roller, and a limiting slide groove is provided on the inner wall of the cleaning cover, and the scraper slides inside the limiting slide groove.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] The highway engineering paver is provided with a lifting component. When in use, the driving motor is started by the general control of the paver to drive the second transmission belt, and the first transmission belt drives the rotating rod to rotate. The rotating rod will drive the threaded rotating rod to rotate, and the articulated block pair will realize that the first threaded block and the second threaded block are threadedly connected to the outer surface of the threaded rotating rod. When the first threaded block and the second threaded block are respectively facing corresponding directions, the inclination angle of the first articulated rod and the second articulated rod increases and the cleaning cover will be pushed downward to descend. When the cleaning cover descends, it will synchronously drive the scraper to descend to the outside of the paving roller. The paving roller rotates to scrape off the solid matter adhered to the surface of the paving roller through the scraper, which is convenient for cleaning the paving roller, thereby extending the service life of the paving roller and the paving effect.

[0014] The highway engineering paver is provided with a first conveying pipe and a second conveying pipe. When asphalt adheres to the outer surface of the paving roller and is inconvenient to clean after cooling, hot air is conveyed through the second conveying pipe and sprayed through the through hole to the outer surface of the paving roller for heating treatment. After the asphalt is heated, it is convenient to scrape it off with a scraper. In addition, through the first conveying pipe, clean water can be further sprayed through the through hole to the outside of the paving roller for further cleaning, thereby improving the cleaning effect of the paving roller.

[0023] In the case implementation, by setting up the lifting component 9, when in use, the driving motor is started through the overall control of the paver to drive the second transmission belt 12, and the first transmission belt 8 is used to drive the rotating rod 11 to rotate. The rotating rod 11 will drive the threaded rotating rod 901 to rotate, and the hinge block 905 will realize the first threaded block 903 and the second threaded block 904 being threadedly connected to the outer surface of the threaded rotating rod 901. When the first threaded block 903 and the second threaded block 904 are respectively facing the corresponding directions, the inclination angle of the first hinge rod 906 and the second hinge rod 907 will increase and the cleaning cover 1 will be pushed downward.

[0024] In the case implementation, when the cleaning hood 1 descends, it will synchronously drive the scraper 4 to descend to the outside of the paving roller 10. The paving roller 10 rotates and the scraper 4 scrapes off the solid matter adhered to the surface of the paving roller 10, making it convenient to clean the paving roller 10, thereby extending the service life of the paving roller 10 and the paving effect.

After the asphalt is heated, it is convenient to scrape it off through the scraper 4.

[0026] In the case implementation, by setting up the first conveying pipe 2, cleaning water can be further sprayed to the outside of the paving roller 10 through the through hole 14 for further cleaning treatment, thereby improving the cleaning effect of the paving roller 10.

[0027] To sum up, the highway engineering paver is provided with a lifting component 9. When in use, the driving motor is started by the overall control of the paver to drive the second transmission belt 12, and the first transmission belt 8 is used to drive the rotating rod 11 to rotate.

When the first threaded block 903 and the second threaded block 904 are respectively facing the corresponding directions, the inclination angle of the first hinge rod 906 and the second hinge rod 907 increases and pushes the cleaning cover 1 downward. When the cleaning cover 1 descends, it will synchronously drive the scraper 4 to descend to the outside of the paving roller 10. The paving roller 10 rotates and the scraper 4 scrapes off the solid matter adhered to the surface of the paving roller 10, which is convenient for cleaning the paving roller 10, thereby extending the service life of the paving roller 10 and the paving effect.

[0028] Furthermore, by providing the first conveying pipe 2 and the second conveying pipe 3, when asphalt adheres to the outer surface of the paving roller 10, it is inconvenient to clean it after cooling. Hot air is conveyed through the second conveying pipe 3 and sprayed through the through hole 14 to the outer surface of the paving roller 10 for heating treatment. After the asphalt is heated, it is convenient to scrape it off through the scraper 4. Furthermore, through the first conveying pipe 2, clean water can be further sprayed through the through hole 14 to the outside of the paving roller 10 for further cleaning, thereby improving the cleaning effect of the paving roller 10.
