Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a flattening device for asphalt pavement construction comprises a cab 1, a cover 2 is fixedly installed at the bottom of the cab 1, a connecting plate 3 is fixedly installed at the front of the cover 2, a roller 4 is fixedly installed at the bottom of the connecting plate 3, a steel wheel 5 is movably sleeved at the back of the roller 4 and positioned at the bottom of the cover 2, an expansion link 6 is fixedly installed at the bottom of the front of the roller 4, a pressing block 7 is fixedly installed at the bottom of the expansion link 6, a first scraper 8 is fixedly installed at one side of the bottom of the cover 2, one side of the first scraper 8 is in contact with one side of the steel wheel 5, a second scraper 9 is fixedly installed at the other side of the bottom of the cover 2, one side of the second scraper 9 is in contact with one side of the other steel wheel 5, a connecting frame rod 10 is fixedly installed at the middle part of the bottom of the cover 2, a, one side fixed mounting of cover 2 has a backup pad 12, and one side fixed mounting of backup pad 12 bottom has a support column 13, and inner hole groove 14 has been seted up to the inside of support column 13, and the top fixed mounting that the inner chamber of support column 13 just is located inner hole groove 14 has a motor 15, and fixed mounting all around of motor 15 lower part has flabellum 16.

The number of the fan blades 16 is four, the lowest height of each fan blade 16 is ten centimeters higher than the bottom of the steel wheel 5, the rotating speed of the inner hole groove 14 is slow, a distance is reserved between the scattered asphalt and the ground, the concave part cannot be smoothed due to too high height, the problems that the rotating speed is too fast and the asphalt flies around are solved, and the performance of leveling the asphalt by the fan blades 16 is improved.

The four telescopic rods 6 and the four pressing blocks 7 are respectively distributed on the front and the back of the steel wheel 5, the front and the back are separately controlled, and the telescopic rods 6 after being stretched enable the bottom of the pressing blocks 7 to be lower than the bottom of the steel wheel 5 by three centimeters, so that the problem that asphalt is scattered outwards when a flattening machine is used for flattening the road edge is solved, the smoothness of the asphalt pavement is improved, and the solidity of the asphalt after roadside compaction is improved.

The middle of the re-filling plate 11 is provided with a straight part with a length of ten centimeters, included angles of one hundred sixty five degrees are formed between the straight part and the two ends of the re-filling plate, and the smaller included angle and the straight part in the middle enable scraped asphalt to be more fully filled in a sunken part, and the redundant asphalt can slide to two sides conveniently, so that the problem that the stuck asphalt forms a sunken part and the scraped asphalt forms a protrusion after being rolled for the second time by the steel wheel 5 is solved, and the flatness of the asphalt pavement is improved.

Wherein, the length that flabellum 16 expandes just exceeds the length ten centimetres of steel wheel 5, has realized the complete flattening of the preceding scattered pitch of spreading, has prevented both sides from flattening perfect problem inadequately, has solved and has flattened the easy problem that produces the small wave and lead to the unevenness of bituminous paving after the flattening, has promoted the flattening machine efficiency problem of flattening the pitch.

The first scraper 8 and the second scraper 9 are arranged in the opposite direction of the advancing direction of the steel wheel 5, and the length of the first scraper 8 and the length of the second scraper 9 are two centimeters longer than that of the steel wheel 5, so that the problem that asphalt with high temperature is easy to adhere to the steel wheel 5 is solved, and the working time length of the steel wheel 5 for flattening the road surface is prolonged.

The working principle is as follows: when in use, after entering the cab 1, a worker starts the flatting machine, the inner hole groove 14 starts to work to drive the fan blades 16 to rotate slowly, the asphalt spread on the ground is smoothed, more asphalt will be scattered along the fan blades 16 to both sides, and a certain amount of asphalt will remain between the four fan blades 16, when the asphalt is sunk, if a small amount of asphalt is left, the residual asphalt can be buried, and a flattening machine rolls forwards, when the roadside is rolled, the telescopic rod 6 on one side extends to enable the pressing block 7 to contact the ground, the asphalt which is diffused outwards when the roadside is rolled and is close to the steel wheel 5 is blocked, the asphalt with higher temperature is pressed by the steel wheel 5, some asphalt can be adhered to the steel wheel 5, and scraping the asphalt by the second scraper 9, pushing the scraped asphalt forwards by the re-filling plate 11 at the moment, backfilling the remained pits, and flattening the pavement again by the other steel wheel 5.
