Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically to an asphalt paving device for airport road surface construction. Background Technology

[0002] Asphalt is a dark brown to black viscous liquid or semi-solid organic material with good viscosity, plasticity and water resistance. It is an important raw material in road engineering, construction engineering and other fields. Asphalt paving refers to the construction process of spreading hot-mix asphalt mixture evenly on the road base to form a flat and solid road surface structure layer. It is a key link in road construction and directly affects the road's performance, service life and driving comfort.

[0003] In existing paving devices, when the asphalt is stirred and rotated by the asphalt agitator to promote its downward flow into the discharge pipe, the increased viscosity can lead to increased stirring resistance, resulting in uneven mixing. This, in turn, affects the uniformity of the discharge and the smoothness of the road surface. Therefore, it is necessary to improve the asphalt paving device for airport road construction to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt paving device for airport road construction to solve the problems mentioned in the background art.

[0026] Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution: an asphalt paving device for airport road construction, including an asphalt storage and insulation tank 1, a support frame 2 fixedly connected to the outside of the asphalt storage and insulation tank 1, a universal wheel 3 fixedly connected to the bottom of the support frame 2, a support plate 4 fixedly connected to the front of the asphalt storage and insulation tank 1, a hydraulic cylinder 5 fixedly connected to the top of the support plate 4, a pressure roller frame 6 fixedly connected to the bottom of the hydraulic cylinder 5, a protective box 7 fixedly connected to the top of the asphalt storage and insulation tank 1, a feed pipe 8 fixedly connected to the top of the asphalt storage and insulation tank 1, a discharge box 11 fixedly connected to the bottom of the asphalt storage and insulation tank 1, a movable discharge mechanism 9 provided on the front of the discharge box 11, and an auxiliary mixing mechanism 10 provided on the top of the asphalt storage and insulation tank 1;

[0028] The movable discharge mechanism 9 includes a movable component 91 and a discharge component 92. The movable component 91 is located on the left side of the discharge box 11, and the discharge component 92 is located on the front of the discharge box 11.

[0029] Furthermore, the active component 91 includes a baffle 911, which is fixedly connected inside the material box 11. A feeding roller 912 is rotatably connected inside the material box 11. A limit plate 913 is fixedly connected to the left side of the feeding roller 912. A first support base 914 is fixedly connected to the left side of the material box 11. A first motor 915 is fixedly connected to the front of the first support base 914. A connecting plate 916 is fixedly connected to the output end of the first motor 915, which facilitates the feeding roller 912 to rotate evenly at 90 degrees each time inside the material box 11, thus cooperating with the baffle 911 to uniformly feed the material.

[0030] Furthermore, the feeding roller 912 contacts the baffle 911, and the limiting plate 913 and the connecting plate 916 are respectively provided with grooves, and the connecting plate 916 is movably connected inside the groove, which makes the feeding process more stable.

[0031] Furthermore, the discharge assembly 92 includes a second support base 921, which is fixedly connected to the front of the discharge box 11. A second motor 922 is fixedly connected to the front of the second support base 921, and a connecting rod 923 is fixedly connected to the output end of the second motor 922. A slide rail frame 924 is fixedly connected to the front of the discharge box 11. A limit plate 925 is slidably connected inside the slide rail frame 924, and a rubber striking plate 926 is fixedly connected to the back of the limit plate 925. This facilitates the reciprocating motion of the rubber striking plate 926, ensuring uniform striking of the discharge box 11 and preventing blockage during the material discharge process.

[0032] Furthermore, the rubber striking plate 926 contacts the material box 11, and the limiting plate 925 and the connecting rod 923 are provided with grooves at corresponding positions, and the connecting rod 923 is movably connected inside the groove, which facilitates a more stable operation.

[0033] Example 2:

[0034] Based on Example 1, please refer to Figure 6Furthermore, in conjunction with Embodiment 1, the auxiliary mixing mechanism 10 includes a third support base 101, which is fixedly connected to the top of the asphalt storage and insulation tank 1. A third motor 102 is fixedly connected to the top of the third support base 101, and a first bevel gear 103 is fixedly connected to the output end of the third motor 102. A connecting frame 104 is rotatably connected inside the asphalt storage and insulation tank 1. A second bevel gear 105 is fixedly connected to the top of the connecting frame 104, and a stirring blade 106 is fixedly connected to the bottom of the connecting frame 104. A mixing frame 107 is rotatably connected inside the connecting frame 104, and a third bevel gear 108 is fixedly connected to the top of the mixing frame 107. This facilitates the opposite rotation of the mixing frame 107 and the stirring blade 106, thereby ensuring thorough mixing of the asphalt raw materials inside the asphalt storage and insulation tank 1.

[0035] Furthermore, the third bevel gear 108 meshes with the first bevel gear 103, and the second bevel gear 105 meshes with the first bevel gear 103, which facilitates a more stable stirring process.

[0036] In actual operation, when this device is used, the operator first introduces the asphalt raw material into the asphalt storage and insulation tank 1 through the feed pipe 8. The third motor 102 then operates, causing the first bevel gear 103 to rotate. This, in conjunction with the second bevel gear 105, causes the connecting frame 104 to rotate inside the asphalt storage and insulation tank 1, thereby rotating the mixing blade 106. The rotation of the first bevel gear 103, in conjunction with the third bevel gear 108, causes the mixing frame 107 to rotate inside the connecting frame 104. This achieves the opposite rotation of the mixing frame 107 and the mixing blade 106, ensuring thorough mixing of the asphalt raw material inside the asphalt storage and insulation tank 1. When 915 is activated, the connecting plate 916 rotates, which, in conjunction with the limiting plate 913, causes the feeding roller 912 to rotate uniformly by 90 degrees each time inside the feeding box 11. This, combined with the baffle 911, ensures uniform feeding. The second motor 922 operates, causing the connecting rod 923 to rotate, which in turn causes the limiting plate 925 to slide inside the slide rail frame 924. This causes the rubber striking plate 926 to reciprocate back and forth, ensuring uniform striking of the feeding box 11 and preventing blockages during the feeding process. The operator pushes the asphalt storage and insulation tank 1, which, in conjunction with the casters 3, propels the device forward. The hydraulic cylinder 5 operates, causing the pressure roller frame 6 to move, thus flattening the laid asphalt.
