By adopting intermittent unloading, it solves the problem that it is difficult to level the materials after they are piled up together when unloaded completely at one time in the traditional way.

[0017] 2. It is convenient to level the materials on the road, and the road surface can also be sprayed during the paving process, avoiding the influence of the external environment and temperature on the paving operation and effect of the materials during the paving process.

[0018] 3. The opening and closing movement of the supporting device can drive the entire scraper to rise and fall. After the material box is opened, the entire moving plate and the scraper below are pulled downward, causing the scraper to touch the ground. When passing through the moving device, the scraper on the ground can lay and level the material that has fallen in front. At the same time, the movement of the cylinder not only drives the scraper to move and scrape, but also generates an air power source through the movement of the moving plate, causing the generated air power to impact the feeding shell and impact the internal helical blade disk to rotate, thereby stirring and crushing the internal material to prevent the material from settling or agglomerating. The spacing between the moving plates can also change the amount of water output at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Detailed usage method and function of this embodiment:

[0035] Put the road base material into the material box 3, drive the conveying mechanism 35 to operate, convey the material in the material box 3 through the conveying mechanism 35, and let it fall into the right side from the inclined surface of the feeding housing 34. Open the blanking valve, and it falls into the two combined material placing boxes 40 below. Drive the motor 43, drive the first fan wheel 41 to rotate upwards to the right through the motor 43. The first fan wheel 41 drives the second fan wheel 42 engaged on the side to move upwards to the left. The first support plate 44 pulls the bottom ends of both sides of the inverted V-shaped driving rod 45 downwards. The top of the inverted V-shaped driving rod 45 pulls the cylinder 12 downwards. With the rotation of the first fan wheel 41 and the second fan wheel 42, the second support plate 47 makes the top of the second support plate 47 push against the inner inclined box 38 and push it to both sides at the same time. At this time, the top of the fourth driving rod 48 pushes the support platform 39 to both sides at the same time, so as to open the combined material placing boxes 40. When the two combined material placing boxes 40 are opened, the material inside the material placing boxes 40 will be unloaded and fall to the ground. The cylinder 12 moves downwards under the pulling force of the inverted V-shaped driving rod 45. The lifting plate 10 presses the first telescopic column 8 and the second telescopic column 9 below to generate a compression movement, and at the same time drives the scraper 18 to move downwards to contact the road surface.

[0036] Drive the telescopic movement between the cylinder 12 and the air rod 11, so that the air rod 11 pushes the first moving plate 13 to the right. When the magnet 51 at the top right of the first moving plate 13 approaches the magnet 52, under the effect of magnetic repulsion, it presses the magnet 52 to move backward, so that the second moving plate 14 slides to the right. The following second moving plate 14 is the same as above, pulling the pusher 4 to drive the whole device to move forward. When the first moving plate 13 and the second moving plate 14 move to the right at the same time under the push of the air rod 11, the scraper 18 at the bottom will level the material unloaded in front. In addition, during the process of the first moving plate 13 and the second moving plate 14 moving to the right, the corrugated compression body 21 connected between them will be in a compressed state. Air pressure will occur in the air compression cavity 27 above the compression body 21, and the air pressure generated inside will enter the air flow channel 30 through the air outlet hole 29 on the side, and enter the feeding housing 34 through the connecting pipe 31. A filter screen is installed at one end of the connecting pipe 31 located inside the feeding housing 34. When the incoming air impact drives the internal helical blade disk 36 to rotate, the helical blade disk 36 rotates to stir and crush the material conveyed upwards inside, avoiding the stirring and crushing of the internal asphalt or filled crushed stones. The water in the water storage cavity 28 is squeezed out from the bottom water dripping hole 23 with the compression of the compression body 21 to supplement water to the road filled with fine stones. Among them, a valve is installed on the conduit 22. When it is necessary to supplement water to the road filler, the valve is opened, and when it is not necessary to supplement water, the valve is closed.

However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
