This scheme provides an asphalt pavement paver for carry out the compaction to asphalt pavement and level and handle, clear up the gyro wheel 2 that flattens that is used for the compaction road surface through cleaning subassembly 3, avoid remaining pitch to be attached to the surface of gyro wheel 2 that flattens for a long time, influence the compaction effect of gyro wheel 2 that flattens, solved among the prior art problem that remaining pitch is difficult to handle in the gyro wheel 2 that flattens.
Specifically, the traction trolley 1 is replaced by a known asphalt compacting practical trolley, and the flattening rollers 2 are driven to rotate when the traction trolley 1 moves; the asphalt on the surface of the ground is compacted through the rotation of the flattening roller 2; and because some pitch is still in a loose state, it will be attached to flattening roller 2, and is difficult to break away from flattening roller 2. Therefore, the cleaning assembly 3 can clean the roll surface of the flattening roller 2 in the working process of the flattening roller 2, and can conveniently remove the asphalt on the surface of the flattening roller 2. As shown in fig. 1 and 2, the left end of the first scraper 32 is rotatably connected to one of the rotating seats 31; the right end of the second scraper 33 is rotatably connected to one of the rotating seats 31; in this regard, the right end of the first scraper 32 and the left end of the second scraper 33 may be angularly adjusted to contact the roll surface of the leveling roller 2, as shown in fig. 3. In order to realize the angle adjustment of the first scraper 32 and the second scraper 33, the first scraper 32 and the second scraper 33 are both connected to an adjusting rod 35 through a connecting arm 34 respectively; the connecting arm 34 is rotatably connected with the first scraper 32 or the second scraper 33 and the adjusting rod 35; when the adjusting rod 35 is lifted, one end of the connecting arm 34 is driven to move, and then the other end of the connecting arm 34 is driven to move, so that the first scraper 32 and the second scraper 33 rotate around the rotating base 31 as an axis, and the right end of the first scraper 32 and the left end of the second scraper 33 are abutted against the surface of the platen roller 2. Since the roll surface of the leveling roller 2 is rotating, when the asphalt on the roll surface rotates to the first scraper 32 and the second scraper 33, the first scraper 32 and the second scraper 33 sweep the asphalt through corners, so as to scrape the asphalt from the leveling roller 2. Meanwhile, the position of the sweeper brush 36 can be vertically adjusted, and the sweeper brush is arranged on the adjusting rod 35; as shown in fig. 3, the sweeper 36 is abutted against the leveling roller 2 only after the sweeper 36 moves downward and passes through the sweeping through opening 30 between the first scraper 32 and the second scraper 33, so that the scraped asphalt on the surface of the leveling roller 2 can be swept. In this scheme, because pitch is attached to behind the roll surface of gyro wheel 2 that flattens, it can be swept away by sweeper 36 through scraping, and the surface of gyro wheel 2 that flattens is difficult to adhere to pitch, and then keeps the cleanliness factor on gyro wheel 2 surface that flattens constantly.

Meanwhile, the air draft device 4 can collect the asphalt remained on the flattening roller 2, so that the collected asphalt can be subjected to surface research to find out the reason that the part is difficult to compact; further, the quality of the asphalt can also be evaluated by calculating the residual asphalt quantity per unit area by calculating the residual asphalt quantity.
Preferably, the bottom of the first scraper 32 is provided with a plurality of discharge ports 321 which are communicated with the inside and the outside.
According to the scheme, the exhaust port 321 can be preferably matched with the air draft device 4, after the asphalt is sucked into the first scraper 32 by the air draft device 4, part of residual asphalt with small particle size can fall to the asphalt ground again through the exhaust port 321 of the first scraper 32, and the residual asphalt with large particle size is not easy to separate from the exhaust port 321 and is difficult to be compacted again, so that the asphalt with large particle size can be recycled to the air draft device 4 through the air draft device 4, and the part of asphalt is prevented from falling to the asphalt ground again.
Preferably, the left end of the second scraper 33 abuts against the right end opening of the first scraper 32, and forms the cleaning passage 30 when the adjusting rod 35 is driven to move.
As shown in fig. 2, the left end of the second scraper 33 abuts against the right end opening of the first scraper 32, so that negative pressure can be formed inside the first scraper 32 by the air draft device 4, and asphalt remaining on the second scraper 33 can be recovered by the negative pressure; meanwhile, as shown in fig. 2, when the left end of the second scraper 33 abuts against the right end opening of the first scraper 32, the first scraper 32 and the second scraper 33 form a horizontally extending plate structure, so that the regularity of the cleaning assembly 3 can be maintained.
