Further, the opening size of the mixing chamber 58 and the number of mixing flaps 39 can be adjusted to adjust the specific laying speed and mixing degree.

Initial position: the driven gear 32 drives the connecting sleeve 31, the chain wheel adjusting rod 11 and the chain wheel shaft 29 to move the front end chain wheel 10 away from the ground. The adjustment slider 52 is controlled to a high position by the adjustment bolt 48 and the adjustment nut 49, and does not abut on the ground. The detection slider 68 is ejected by the detection spring 67 to abut against the half-turn gear 53. The mixing flap 39 closes off the individual through openings of the mixing chamber 58.

The method for flattening the paved edge of the asphalt pavement comprises the following specific steps:

the first step is as follows: and a material clearing mechanism and an adjusting and detecting mechanism are arranged. The adjusting motor 34 is started to drive the driving gear 33 to rotate through the driving rotating shaft 59, the driving gear 33 drives the driven gear 32 to rotate, the driven gear 32 drives the connecting sleeve 31 to rotate, the connecting sleeve 31 drives the chain wheel adjusting rod 11 to rotate, the chain wheel adjusting rod 11 drives the chain wheel bearing 28 to rotate, the chain wheel bearing 28 drives the chain wheel shaft 29 to rotate, the chain wheel shaft 29 drives the transmission roller chain and the material cleaning mechanism to rotate, and when the shoveling shaft 46 abuts against the ground, the rotation is stopped. The adjusting slide block 52 is unlocked by adjusting the tightness degree of the adjusting bolt 48, and the vertical position of the adjusting slide block 52 and the auxiliary mechanism thereof is adjusted, so that the test ball 15 is abutted against the asphalt pavement.

And secondly, cleaning overflowing asphalt. The device can be attached to an asphalt paver and can also be endowed with independent power. The chain wheel motor 30 is started, the chain wheel motor 30 drives the chain wheel shaft 29 to rotate, the chain wheel shaft 29 drives the chain wheel 10, the chain wheel 10 drives the transmission roller chain 35 to rotate, the transmission roller chain 35 drives the shoveling plate 44, the shoveling roller 45, the shoveling shaft 46 and the shoveling transport case 47 to rotate, and the shoveling roller 45 is always abutted to the ground, so that when the shoveling roller 45 encounters overflowing asphalt, the shoveling plate 44 can shovel the overflowing asphalt, and along with the continuous movement of the chain wheel 10, the excessive asphalt is loaded into the shoveling transport case 47 and is transported to the next step.

The third step: and (4) separating the asphalt. The asphalt conveyed by the shoveling and conveying box 47 enters the separating inner cylinder 19 under the action of gravity. The separation motor 17 is started, the separation motor 17 drives the separation inner cylinder 19 to rotate through the separation transmission shaft 16, under the centrifugal effect, asphalt is thrown to the separation outer cylinder 22 through the separation holes 20, sand and stone in the separation outer cylinder are left in the separation inner cylinder 19, and the separation scraper 21 scrapes the asphalt on the separation outer cylinder 22 clean, so that the cleaning effect is achieved.

And fourthly, filling the asphalt. When the detection mechanism detects that the asphalt is lack at a certain position, the mixing motor 36 is started, the mixing motor 36 drives the mixing shaft 37, the mixing roller 38 and the mixing turning plate 39 to rotate, and the asphalt in the asphalt storage tank 23 and the sand in the stone storage tank 24 are alternately mixed and paved to the place with the lack of the asphalt.

The fifth step: and (4) compacting the asphalt. In the course of asphalt paving, compaction of the asphalt plays a very important role. The movement of the compaction roller 25 allows compaction of the asphalt already laid. At the same time, the consistency of the asphalt height can be ensured due to the existence of the compaction spring 40.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
