Problems solved by technology
[0003] The temperature of asphalt concrete paving on the road surface is not lower than 110℃~130℃. Due to the temperature factor, the viscosity of some asphalt will be strengthened. When the road paver is rolling, some asphalt concrete blocks will be attached to the surface of the rolling wheel. Cleaning up in time will make the rolling wheel unable to get close to the road surface, resulting in uneven compaction

Embodiment Construction
[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0030] see Figure 1-Figure 7 Shown, the present invention provides a kind of paving machine technical scheme that road construction is used:
[0031] Such as figure 1 and figure 2 As shown, its structure includes a cab 1, a car body 2, a push wheel 3, a rolling wheel 4, and a cleaning mechanism 5. The cab 1 above the car body 2 is connected with a push wheel at the rear end of the car body 2. 3 and the front end is connected with a cleaning mechanism 5, and a rolling wheel 4 is installed in the middle of the cleaning mechanism 5;
[0032] Wherein, the cleaning mechanism 5 is composed of a return frame 6, a front scraping device 7, a rear scraping device 8, a cyclone device 9, a bearing seat 10, and a rotating shaft 11, and the rotating shaft...

The invention discloses a paver for road construction. The paver structurally comprises a cab, a vehicle body, pushing wheels, rolling wheels and cleaning mechanisms, the cab is arranged above the vehicle body, the rear end of the vehicle body is connected with the pushing wheels, the front end of the vehicle body is connected with the cleaning mechanisms, and the rolling wheels are arranged between the cleaning mechanisms. The paver has the beneficial effects that the scraping devices of the same structure are installed at the front end and the rear end of the rolling wheel, the road roller can independently work according to forward and reverse rotation of the rolling wheel, the scraping plates on the scraping devices can remove filtering blocks attached to the surface of the rolling wheel, and the phenomenon that the rolling wheel cannot be attached to the road surface, and consequently compaction is uneven is prevented.
Description
technical field [0001] The invention relates to a paving machine for road construction, which belongs to the technical field of road construction equipment. Background technique [0002] In the construction of urban and rural roads, asphalt concrete is often used as the material to pave the road between urban and rural roads. After the asphalt concrete is laid, it needs to be rolled repeatedly by the paving machine before it can be put into use. It is often divided into initial pressure and re-pressure. and final pressure three stages, the completion temperature of the rolling is not lower than 65°C, when the paving machine repeatedly rolls the asphalt concrete, there are the following deficiencies: [0003] The temperature of asphalt concrete paving on the road surface is not lower than 110℃~130℃. Due to the temperature factor, the viscosity of some asphalt will be strengthened. When the road paver is rolling, some asphalt concrete blocks will be attached to the surface of ...
