Example 2:

in this embodiment, on the basis of embodiment 1, the asphalt paving device for road machine construction is structurally optimized, and the function of supplementing material to the crushing mechanism 2, the function of cleaning the road surface in front of the paving device, and the lighting function are added.

Because the position of the feeding hole 221 of the box body 22 is higher in the construction process, the car body 1 is also in a running state, the efficiency of manual filling work for the feeding hole 221 on the box body 22 is low, and the danger coefficient is large. Therefore, a charging mechanism 5 is added to the vehicle body 1 of the asphalt paving apparatus for road construction machine, and the asphalt raw material is replenished by the machine at any time.

As shown in fig. 1 and 4, the charging mechanism 5 is composed of a support rod 51, a connecting rod 52, a hinge shaft 53, a scoop 54, and a storage box 55. The material storage box 55 is a hot-melt asphalt material storage carrier with an open top surface, and is mounted on the top surface of the bottom plate 11 of the vehicle body 1, and has a moderate height above the ground and a large opening range. Facilitating the pouring of the pre-melted bitumen feedstock therein for storage. The support rod 51, the connecting rod 52 and the material spoon 54 form a multi-joint mechanical arm structure through a hinge shaft 53, and are driven to extend and retract by an air cylinder or a hydraulic cylinder, and the principle of the multi-joint mechanical arm structure refers to an extending arm structure of an excavator and is not described herein. The material spoon 54 is driven to reciprocate in the feeding hole 221 and the storage box 55 of the box 22 of the crushing mechanism 2 through the extension and contraction of the support rod 51 and the connecting rod 52. The asphalt material in the storage bin 55 is continuously added to the shredder mechanism 2.

If a large amount of floating dust or impurities exist on the asphalt pavement, the adhesion effect of asphalt on the ground is affected, so that the asphalt adheres to the surface of the rolling plate 41 or the surface of the compaction roller 13 to cause the asphalt pavement to be missed, and the front pavement of the running path of the paving device needs to be cleaned during asphalt paving construction. Therefore, the cleaning mechanism 6 is added to the front end of the vehicle body 1 of the asphalt paving apparatus for road machine construction. The road surface is cleaned in time along with the advance of the vehicle body 1.

As shown in fig. 1, the cleaning mechanism 6 is composed of a cleaning head 61, a cleaning rotation shaft 62, and a drive motor 63. The driving motor 63 is installed on the bottom plate 11, the cleaning head 61 is installed at the end of the cleaning rotating shaft 62, and the cleaning rotating shaft 62 is coupled to the bottom plate 11 and is in transmission connection with the driving motor 63. The effect that the driving motor 63 is started to drive the cleaning head 61 to rotate to clean the road surface is achieved.

Because the construction time of road construction is urgent, night operation is often required, and in order to adapt to the night construction environment, the lighting mechanism 7 is installed at the front end of the asphalt paving device for road machine construction.

As shown in fig. 1, the illumination mechanism 7 is composed of an illumination lamp 71 and an adjustment base 72. The illuminating lamp 71 is hinged at the top end of the adjusting seat 72. The irradiation angle of the illumination lamp 71 can be swingably adjusted.
