[0002] In existing technologies, during the construction of asphalt pavements for municipal roads and urban branch roads, it is common to encounter situations where small sections of asphalt pavement cannot be constructed mechanically, requiring manual paving and compaction of small areas. The main problems with existing asphalt compaction devices for municipal road construction include: 1) General compaction devices have a fixed self-weight and lack self-weight adjustment capabilities, thus failing to meet the compaction requirements of asphalt materials with different hardness or thicknesses. 2) During compaction operations, asphalt material easily adheres to the rollers; if not cleaned promptly, this severely impacts the compaction quality and effectiveness of the pavement.

[0003] Therefore, we need to develop a flattening device with self-weight adjustment and cleaning capabilities to solve the above problems. Summary of the Invention

[0018] The push-pull rod 4 mainly consists of an upper snap-in section 401 and a lower locking section 402. The size of the snap-in section 401 is smaller than that of the locking section 402. The bottom end of the snap-in section 401 is connected and fixed to the top end of the locking section 402. A handle 403 is fixed to the top end of the snap-in section 401, and a support plate 404 is fixed to the bottom end of the locking section 402. The bottom of the support plate 404 is hinged to the top of the connecting bracket 1 through a hinge lug. The upper sliding sleeve 02 has a counterweight 405, which abuts against the support plate 404. The center of the counterweight 405 has a locking hole 406 that runs through it from top to bottom. The side wall of the counterweight 405 has a locking groove 407 that runs through it from top to bottom and communicates with the locking hole 406. The shape and size of the locking hole 406 match the cross-sectional shape and size of the locking section 402, and the size of the locking groove 407 matches the cross-sectional size of the locking section 401.

[0019] A scraping assembly 5 is provided on both sides of the flattening cylinder 3 on the connecting bracket 1. The scraping assembly 5 includes a fixing frame 501, which is fixed on both sides of the connecting bracket 1. A fixing plate 502 is fixedly connected between the fixing frames 501. A sliding hole 504 is provided on the side of the fixing plate 502 near the flattening cylinder 3. A spring 503 is provided in the sliding hole 504. A scraper 506 is provided between the flattening cylinder 3 and the fixing plate 502. A sliding column 505 is fixed on the side of the scraper 506 near the fixing plate 502. The sliding column 505 is slidably connected in the sliding hole 504. The scraper 506 abuts against the side surface of the flattening cylinder 3 under the action of the spring 503. The fixing plate 502 forms an elastic structure with the scraper 506 through the spring 503, the sliding hole 504 and the sliding column 505. One end of the spring 503 is fixedly connected to the sliding column 505 and the other end of the spring 503 is fixedly connected to the bottom of the sliding hole 504.

[0020] The adjustable weight flattening roller for manual paving of municipal asphalt pavement described in this embodiment works on the following principle: When installing the counterweight 405, the required number of counterweights 405 is first calculated based on the compaction requirements of asphalt materials with different hardness and asphalt layers with different thicknesses. Then, all counterweights 405 are installed sequentially on the push-pull rod 4. During installation, the counterweight 405 is first inserted into the snap-in section 401 of the push-pull rod 4 through the snap-in groove 407, and then slidably locked onto the snap-in section 402 of the push-pull rod 4 through the snap-in hole 406 and abuts against the support plate 404, thus completing the installation of the counterweight 405. When cleaning the adhered asphalt material, the elasticity of the spring 503 inside the fixing plate 502 can automatically drive the sliding column 505 to move. The sliding column 505 slides along the sliding hole 504, so that the scraper 506 is stably and tightly attached to the outer wall of the flattening cylinder 3, effectively scraping away residual asphalt.
