Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figure 1-2 shown, the ultra-thin wearing course asphalt mixture paving device of this embodiment includes a support plate 1, rollers 2 at the bottom of the support plate 1, a storage tank 3 above the support plate 1, a connecting rod 4 fixedly installed on the left side of the support plate 1, and a pressing roller 5 rotatably installed between the connecting rods 4. The pressing roller 5 can compact the paved asphalt. A discharge port 6 is provided at the lower left position of the storage tank 3. A fixing plate 7 is fixedly installed at the middle left position of the storage tank 3. A hydraulic cylinder 8 is fixedly installed below the fixing plate 7. A chute 9 is provided on the left side of the storage tank 3. A sealing plate 10 is slidably installed in the chute 9. One end of the bottom of the hydraulic cylinder 8 is fixedly connected to the sealing plate 10. During the process of the hydraulic cylinder 8 driving the sealing plate 10 to move up and down, the size of the discharge port 6 is adjusted. A feeding chute 11 is obliquely arranged at the lower left position of the discharge port 6. An adjusting mechanism 12 for adjusting the feeding width is arranged in the feeding chute 11. The adjusting mechanism 12 is used to adjust the asphalt feeding width, so as to be suitable for paving roads with different widths.

[0022] Furthermore, the adjusting mechanism 12 includes a baffle 1201 and a limit bolt 1202 used in cooperation with the baffle 1201. One end of the baffle 1201 close to the discharge port 6 is rotatably connected to the feeding chute 11. The limit bolt 1202 is threadedly connected to the side wall of the baffle 1201. By adjusting the limit bolt 1202, the baffle 1201 can be lifted to different angles, thereby realizing the adjustment of the feeding width.

[0023] Furthermore, a connecting plate 13 is fixedly installed above the right side of the support plate 1, and a connecting hole 14 is provided on the connecting plate 13.

[0024] Furthermore, a stirring device 15 is arranged in the storage tank 3, and a feeding port 16 is also arranged at the top of the storage tank 3.

[0025] Working principle: The asphalt mixture is injected into the storage tank 13 through the feeding port 16. During the paving process, first, adjust the adjustment mechanism 12 according to the width of the road surface to be paved. When adjusting, by turning the limit bolt 1202, during the process of turning the limit bolt 1202, the angle at which the baffle 1201 is lifted changes. Then, adjust the opening and closing size of the discharge port 6 according to the thickness of the asphalt on the road surface to be paved to adjust the discharging speed of the asphalt. When adjusting, during the process of the hydraulic cylinder 8 driving the sealing plate 10 to move up and down, the size of the discharge port 6 is adjusted. The connecting hole 14 at one end of the connecting plate 13 is connected to the mobile device. During paving, the asphalt mixture inside the storage tank 3 passes through the gap between the bottom of the sealing plate 10 and the discharge port 6, and then flows into the inclined feeding chute 11. After being limited by the baffle 1201, it scatters onto the road surface, and the pressing roller 5 can compact the scattered and paved asphalt.
