Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] Figures 1-7 This is a specific embodiment of the present invention, which is an integrated machine for dust removal, paving, and leveling of asphalt roads, such as... Figure 1 As shown, the trailer 1 is connected to the rear of the tractor. The trailer 1 is equipped with a dust suction device 2, a fiberglass grating laying device 3, a flattening mechanism 6, an asphalt mixture outflow device 4, and a leveling device 5 in sequence. The trailer 1 can complete the dust removal, fiberglass grating laying, asphalt mixture paving and leveling work by moving forward once.

[0035] like Figure 2 As shown, the trailer 1 includes a trailer hook 102 that connects to the tractor and a flat bottom plate 101. A dust suction device 2, a fiberglass grating laying device 3, a flattening mechanism 6, an asphalt mixture outflow device 4, and a leveling device 5 are all installed on the bottom plate 101.

[0036] like Figure 3 As shown, the vacuuming device 2 includes a vacuum chamber 202 disposed above the base plate 101, and the vacuum chamber 202 is connected to a plurality of vacuum ports 201 disposed on the base plate 101 below it.

[0037] like Figure 5 Figure 6 As shown, the fiberglass grid laying device 3 includes a gate-shaped enclosure 301 set above the base plate 101. A support plate 302 is detachably connected to the opening of the enclosure 301. A bearing is set at the center of the support plate 302. A coupling with a drive motor is provided at one end of the enclosure 301 opposite to the support plate 302. The support plate 302 is fixedly connected to the enclosure 301 by a stop pin 303. A slot is opened at the front end of the side of the enclosure 301 where the servo motor is installed as an operation port 308. The fiberglass grid roll 7 is rotatably installed on the support plate 302 and the enclosure 301. The base plate 101 has a rectangular slot as a fiberglass geogrid lowering port 309. The fiberglass geogrid lowering port 309 can be set at the front or rear end. If the purchased fiberglass geogrid 701 has too high hardness, the head end of the fiberglass geogrid 701 that has just been unrolled may lift up on the ground, affecting the subsequent asphalt mixture paving. Therefore, setting the fiberglass geogrid lowering port 309 at the rear end allows the lifted part of the head end of the fiberglass geogrid 701 to face downwards and be flattened by the ball bearing 602. If the purchased fiberglass geogrid 701 has low hardness, the fiberglass geogrid lowering port 309 can be set at either the front or rear end. The center of the base plate 101 of the fiberglass geogrid laying device 3 has a groove as a hidden groove 304. A linear slide 305 is installed in the hidden groove 304. A first lifting rod 306 is fixed on the slider of the linear slide 305. A support plate 307 is fixedly connected to the top of the first lifting rod 306.

[0038] like Figure 2 As shown, a flattening mechanism 6 is provided behind the fiberglass geogrid lowering port 309. The flattening mechanism 6 includes several second lifting rods 601 connected vertically in parallel below the base plate 101, and ball bearings 602 are installed at the bottom of the second lifting rods 601. When bulges or wrinkles may occur during the laying process of the fiberglass geogrid, the flattening by the ball bearings 602 can reduce the probability of this happening.

[0039] like Figure 4 Figure 6 As shown, the asphalt mixture outflow device 4 includes an asphalt mixture storage bin 401 installed on a base plate 101. An electric cylinder 402 is provided at the front end of the bottom of the asphalt mixture storage bin 401. An asphalt mixture outflow outlet 403 is opened on the base plate 101 behind the electric cylinder 402. A gate is provided on the asphalt mixture outflow outlet 403. The gate is driven by the electric cylinder 402 to control the opening degree of the asphalt mixture outflow outlet 403. An inclined plate 404 is attached to the base plate 101 behind the asphalt mixture outflow outlet 403. The lowest point of the inclined plate 404 is located at the asphalt mixture outflow outlet 403.

[0040] like Figure 3As shown, the leveling device 5 includes lifting frames 501 installed on both sides of the bottom of the asphalt mixture outlet device 4, and pressure rollers 502 are installed on the lifting frames 501. When it is necessary to lay asphalt pavement of different thicknesses, this can be achieved by adjusting the height of the lifting frames 501 and the opening degree of the asphalt mixture outlet 403.

[0041] Based on the above-mentioned all-in-one machine, the construction method is as follows:

[0042] S1, Preparation stage: Connect the trailer 1 to the tractor, adjust the lifting frame 501 and the second lifting rod 601 to the required position, then pour the heated asphalt mixture into the asphalt mixture storage bin 401, and use a crane to send the fiberglass grid roll 7 into the fiberglass grid laying device 3 and install and fix it.

[0043] S2, the tractor moves at a constant speed on the road where asphalt mixture needs to be laid. The dust suction device 2 sucks up the dust and water on the road surface. The servo motor drives the fiberglass grid roll 7 to rotate and lay the fiberglass grid 701 on the road. The flattening mechanism 6 flattens the fiberglass grid 701. The crane places the fiberglass grid roll 7 on the pallet 307. Through the movement of the first lifting rod 306 and the linear slide 305, the rotating shaft 702 of the fiberglass grid roll 7 is connected to the coupling. Then the support plate 302 is fastened to the enclosure 301. The pallet 307 is lowered into the hidden groove 304. The servo motor can then drive the fiberglass grid roll 7 to rotate. The construction workers stand on both sides of the fiberglass grid laying device 3 and reach out from the support plate 302 and the operating port 308 to lower the head end of the fiberglass grid 701 of the fiberglass grid roll 7 into the fiberglass grid lowering port 309.

[0044] S3, the electric cylinder 402 controls the opening degree of the asphalt mixture flow outlet 403, and the asphalt mixture flows onto the fiberglass grid 701.

[0045] S4, roller 502, smooths the asphalt mixture.

[0046] If the fiberglass grating roll 7 cannot be laid smoothly on the road surface in the initial stage, the construction personnel must manually deliver the fiberglass grating 701 to the fiberglass grating lower opening 309 during the initial vehicle movement until the end of the fiberglass grating 701 is squeezed by the ball bearing 602, then it can be pushed down manually without further manual operation. To better achieve this function, the ball bearing 602 can also be replaced with a roller with a drive motor.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
