Detailed Description
As shown in fig. 1 to 7, an embodiment of the present utility model will be described in detail:
a road asphalt paving device, which comprises a bearing vehicle, a connecting frame 3 and a scraping plate 5; the carrier is used for unrestrained pitch building stones, and link 3 is fixed in the rear end of carrier, and scraper blade 5 is connected on link 3.
During paving, asphalt stones are placed on the carrier, so that the asphalt stones are scattered from the rear end of the carrier and the position in front of the scraper 5 in the forward moving process of the carrier, after the scattered asphalt stones fall on a road surface, the carrier is continuously moved to drive the scraper 5 to move forward through the connecting frame 3, and accordingly the asphalt stones falling on the road surface are pushed horizontally through the scraper 5, and accordingly the asphalt stones on the road surface are scraped horizontally at the lower end of the scraper 5;
and compacting the flattened asphalt stones by the road pressing equipment.
Further:
through setting up scraper 5 slope, make things convenient for scraper 5 at the in-process of moving forward, through the inclination of self, with the in-process downwardly directed that pitch building stones pushed forward, guarantee pitch building stones tiling on the road surface.
Further:
through setting up dull and stereotyped 6 in the lower extreme of scraper blade 5, make the lower terminal surface of dull and stereotyped 6 carry out the flat stone of spreading to scraper blade 5 again and scrape, further guarantee the level and smooth of road surface.
Further:
the reinforcing plate 7 is fixed the trailing flank of scraper blade 5, and scraper blade 5 and reinforcing plate 7 all sliding connection are in link 3, and adjusting screw 8 rotates on reinforcing plate 7 and with link 3 threaded connection.
The adjusting screw rod 8 is rotated, and the adjusting screw rod 8 and the connecting frame 3 are in threaded transmission, so that the adjusting screw rod 8 drives the scraping plate 5 to lift and slide in the connecting frame 3, the distance between the lower end of the scraping plate 5 and the original road surface is changed, and the thickness of asphalt stone paved on the road surface is adjusted;
through reinforcing plate 7 setting, guaranteed the intensity of scraper blade 5, take place deformation when avoiding scraper blade 5 to scrape the flat pitch building stones, simultaneously through the setting of reinforcing plate 7, guaranteed intensity and spacing intensity of being connected between scraper blade 5 and link 3, avoid blocking between scraper blade 5 and the link 3, unable slip.
As shown in fig. 1-7:
the bearing vehicle comprises a frame 1, a roller set 2 and a hopper 9, wherein the hopper 9 for containing asphalt stones is connected to the upper end of the frame 1, and the rear end of the hopper 9 is provided with an opening, so that the asphalt stones can be conveniently scattered onto a road surface in front of the scraper 5 through the opening; the two roller groups 2 respectively rotate at the lower ends of the front side and the rear side of the frame 1 to form a support for the frame 1, wherein the roller groups 2 comprise a support shaft arranged on the frame 1 and rollers rotating at the two ends of the support shaft, so that the frame 1 is supported by the four rollers and the frame is convenient to move on a road surface.
