[0052] Working principle:

[0053] When the user uses the device to pave the road, the paving material (asphalt mixture or cement concrete) needs to be poured into the feeding hopper 11 first, and the material will enter the feeding system inside the paving machine body 1, be uniformly distributed transversely by the spiral distributor behind the screed mechanism 13, and drive the paving machine body 1 to run by the driving caterpillar 12, so as to realize the paving of the road. When the device is paving, the user can start the two motors 3, and the rotation of the two motors 3 will drive the transmission rods 31 to rotate in opposite directions. The rotation of the transmission rods 31 will drive the first fixed block 32 and the second fixed block 33 to rotate. The rotation of the first fixed block 32 will drive the two C-shaped rods 4 on the sides to rotate through the first extension rods 43. The rotation of the C-shaped rods 4 will drive the scrapers 5 to rotate through the positioning plates 53 and the second extension rods 51. When the scrapers 5 rotate, they will scrape some debris (such as stones or soil blocks, etc.) on the road. When the C-shaped rods 4 rotate and contact the end of the triangular plate 61, the end of the triangular plate 61 is chamfered, and at this time the C-shaped rods 4 will be lifted upward when they contact the end of the triangular plate 61, that is, the first spring 42 and the first extension rod 43 will be compressed. The upward movement of the C-shaped rods 4 will drive the scrapers 5 to move upward through the positioning plates 53, the second extension rods 51 and the second springs 52. The upward movement of the scrapers 5 will move away from the debris pile, so as to avoid the rotation of the scrapers 5 bringing the debris pile back to the bottom of the driving caterpillar 12. After the C-shaped rods 4 rotate away from the end of the triangular plate 61, the first extension rods 43 will push the C-shaped rods 4 to move downward and reset. The downward movement of the mounting block 41 of the C-shaped rods 4 will contact the second fixed block 33, and the second fixed block 33 will limit the movement of the mounting block 41 and the C-shaped rods 4. In this way, the front debris of the driving caterpillar 12 can be swept back and forth. The second spring 52 and the second extension rod 51 are arranged between the positioning plate 53 and the scraper 5. When the scraper 5 encounters a large piece of debris during scraping, the flexible contact between the scraper 5 and the debris can be achieved through the elasticity of the second spring 52, so as to avoid the rigid contact causing serious wear of the scraper 5. In the existing paving equipment, no cleaning mechanism is arranged in front of the two driving caterpillars 12. If there are scattered debris or mixture under the two driving caterpillars 12, the driving caterpillars 12 will be lifted, which will cause the paving machine body 1 to be unbalanced, affect the flatness of the road paving, and result in poor road paving effect. The device is provided with a cleaning mechanism, which can drive the two scrapers 5 on the transmission rods 31 to rotate and scrape the debris on the road on the side where the driving caterpillar 12 advances, so as to avoid affecting the advancement of the driving caterpillar 12 and ensure the stable advancement of the driving caterpillar 12 and the paving machine body 1, that is, to ensure the flatness of the road paving. Moreover, the device is provided with the mounting vertical rod 6 and the triangular plate 61. When the scraper 5 is cleaned to the outside of the driving caterpillar 12 by the C-shaped rod 4, the scraper 5 can be lifted by the triangular plate 61 on the C-shaped rod 4, away from the debris pile, so as to avoid the scraper 5 scraping the debris pile back to the bottom of the driving caterpillar 12.And the device through the second telescopic rod 51 and the second spring 52 between the scraper 5 and the positioning plate 53, when the scraper 5 encounters the quality of the larger debris, can be through the elasticity of the second spring 52, so that the scraper 5 and the flexible contact between the debris, avoid rigid contact to the scraper 5 cause serious wear.

[0054] Finally, it should be noted that: apparently, the above examples are merely for the purpose of clearly illustrating the utility model, and not limited to the implementation. For those skilled in the art, on the basis of the above description can also be made in other different forms of changes or variations. Here need not and can not be exhausted to all the implementation. The obvious changes or variations derived from still within the scope of the utility model.
