DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment 1: please refer to Figures 1-5 The present application provides a technical solution: a municipal road construction asphalt paving device, which comprises a rolling assembly 1, and a scraping assembly 2 is arranged below the rolling assembly 1, the scraping assembly 2 comprises a fixed plate 21, both ends of the bottom of the fixed plate 21 are fixedly connected with sliding rods 22, the surfaces of the sliding rods 22 are slidably connected with sliding blocks 23, the bottoms of the sliding blocks 23 are movably connected with scrapers 25, the side surfaces of the scrapers 25 are movably connected with limiting rods 26, a second cylinder 24 is used for pushing the sliding block 23 movably connected at one end to move towards one end of the sliding rod 22, when the sliding rod 22 moves, the scrapers 25 movably connected at both ends of the bottom of the sliding rod 22 will move forward with the sliding rod 22, since one end of the limiting rod 26 movably connected on the side surface of the scraper 25 is movably connected on the side surface of the feeding hopper 11, the position of the rotation of the scraper 25 can be limited, when the scraper 25 rotates around the bottom of the sliding block 23 to the position perpendicular to the ground, it stops, a plurality of spike structures are arranged on the bottom of the scraper 25, which can scrape and level the asphalt discharged from the discharge port 110.

[0024] Please refer to Figures 1-5The rolling assembly 1 comprises a feeding hopper 11, support frames 14 movably connected to both ends of the side of the feeding hopper 11, a compression roller 15 movably connected to one end of the support frame 14, a connecting piece 140 protruding from the top of the support frame 14, a first air cylinder 12 movably connected to the side of the connecting piece 140, and the other end of the first air cylinder 12 movably connected to the top of the feeding hopper 11. The first air cylinder 12 is used to drive the support frame 14 connected to the connecting piece 140 to rotate around one end of the support frame 14 when it is extended or retracted, so that the compression roller 15 arranged at the other end of the support frame 14 is downwardly pressed to preliminarily roll the asphalt scraped flat by the scraper 25. Since the asphalt pavement still needs to be re-rolled to ensure the stable molding of the asphalt mixture, the pavement is generally rolled by a double-wheel vibrating road roller, so as to ensure the stability and solidity of the pavement. One end of a limiting rod 26 is movably connected to the side of the feeding hopper 11, and the limiting rod 26 is used to fix the scraper 25 when the scraper 25 is rotated to be perpendicular to the ground, so as to avoid the uneven force on the scraper 25 and the tilting of the scraper 25 when the scraper 25 is used to scrape the asphalt. A discharge port 110 is formed in the bottom of the feeding hopper 11 near the side of the scraper 25, and a slope is formed on the side of the discharge port 110, so that the asphalt dispersed by the spiral blade 13 can be better discharged.

[0025] Please refer to Figures 4-5 A second air cylinder 24 is fixedly connected to the middle of the sliding block 23, one end of the second air cylinder 24 is fixedly connected to the surface of the feeding hopper 11, and the scraper 25 is movably connected to the bottom of the sliding block 23 through shaft pins. Through the fixing effect of the feeding hopper 11, the second air cylinder 24 can drive the sliding block 23 fixedly connected to one end to move.

[0026] Please refer to Figures 2-5 A spiral blade 13 is rotatably connected to the bottom of the inner cavity of the feeding hopper 11, the blades of the spiral blade 13 are oppositely arranged and located on the same central axis, a motor is arranged on the connecting part of the support frame 14 and the compression roller 15, and the output end of the motor is fixedly connected to the compression roller 15. Since the directions of the blades arranged at both ends of the spiral blade 13 are different, when the asphalt enters the inside of the feeding hopper 11, the asphalt will be dispersed from the middle to both ends by the spiral blade 13, so as to avoid the adhesion of the asphalt due to the excessively high temperature of the asphalt, which causes the asphalt to be difficult to be scraped flat after being discharged. The compression roller 15 is used to preliminarily roll the asphalt, so that the flatness of the asphalt surface meets the requirements of road construction, and facilitates the subsequent re-rolling and final rolling.

[0027] The fixedly connected slider 23 at one end is pushed by the second cylinder 24 to move to one end of the slide rod 22, the scraper 25 movably connected at the bottom of the slide rod 22 moves forward with the slide rod 22, the limiting rod 26 is movably connected at one end of the side of the feeding hopper 11, the position of the scraper 25 can be limited, so that the scraper 25 is not inclined due to uneven force when scraping the asphalt, the scraper 25 is provided with a plurality of tine structures at the bottom, which can scrape the asphalt discharged from the discharge port 110, and the first cylinder 12 drives the support frame 14 to rotate around one end of the support frame 14 when extending and retracting, so that the pressure roller 15 provided at the other end of the support frame 14 is downward, and the asphalt scraped by the scraper 25 is preliminarily rolled.

[0028] Embodiment 2: please refer to Figure 6 The utility model provides a technical scheme: a municipal road construction asphalt paving device, including feeding hopper 11, the bottom of feeding hopper 11 is close to the pressure roller 15 and is equipped with the discharge port 110 at one end, the discharge port 110 is fixedly connected with the right angle scraper 250 above, the right angle scraper 250 can directly scrape the asphalt that discharges through the discharge port 110, and the cost of asphalt paving device is reduced, and scraping is more convenient.
