[0034] like Figure 1-6 As shown, this embodiment proposes an asphalt pavement maintenance spraying device, including a bearing plate 1, and also including a material box 2, which is fixedly installed at the top center of the bearing plate 1 and is used to contain maintenance liquid; a stirring component 3, which is installed in the inner cavity of the material box 2 and is used to stir the maintenance liquid in the inner cavity of the material box 2; an adjustable spraying mechanism 4, which is installed on the outer side wall of the material box 2;

[0035] Among them, the adjustable spraying mechanism 4 includes a slide plate 401 fixedly installed on the outer wall of the material box 2, a slide rod 402 slidably connected to the inner wall of the slide plate 401, a fixed block 403 fixedly arranged at one end of the slide rod 402, a telescopic rod 404 fixedly installed between adjacent fixed blocks 403, a scissor-type connecting rod group 405 fixedly arranged at the bottom of any fixed block 403, an electric telescopic rod 406 fixedly installed at the intersection above the middle section of the scissor-type connecting rod group 405, a short tube 409 rotatably connected at the intersection below the scissor-type connecting rod group 405, a hose 407 fixedly connected between any adjacent short tubes 409, and a nozzle 408 fixedly arranged below any group of short tubes 409, and an evenly distributed adjustment plate assembly 5 is fixedly installed at one end of the top of the scissor-type connecting rod group 405 away from the telescopic rod 404, which can adapt to road surfaces of different widths while ensuring the uniformity of spraying coverage, thereby avoiding the occurrence of missed spraying.

[0036] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the adjustment plate assembly 5 includes a mounting seat 501 fixedly installed above one end of the scissor-type link group 405 and evenly distributed, and any group of mounting seats 501 is movably connected to the top with an angle connector 502, and the other end of the angle connector 502 is fixedly installed with a first baffle 503, and any group of first baffles 503 are slidably connected to the outer wall with a second baffle 504, and the first baffles 503 and the second baffles 504 are staggered, so as to facilitate the adjustment of the edge line position of the spraying range and make the spraying on the edge of the road more uniform.

[0037] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the stirring assembly 3 includes a driving stirring shaft 301 fixedly mounted on the top of the material box 2, and the outer wall of the driving stirring shaft 301 is fixedly mounted with evenly distributed stirring blades 302, and a protective cover 303 is fixedly arranged at the center of the top of the material box 2 and covers the outside of the output end of the driving stirring shaft 301, a water inlet 6 is fixedly mounted on the top of the material box 2, and a water outlet 7 is also arranged at the bottom of one end of the material box 2 close to the adjustable spraying mechanism 4, so as to facilitate the uniform stirring of the curing liquid in the inner cavity of the material box 2.

[0038] like Figure 1 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a water pump 8 is connected to one end of the water outlet 7, the output end of the water pump 8 is fixedly connected to the hose 407 located below the middle of the scissor-type connecting rod group 405, and the bottom of the water pump 8 is connected to the top of the supporting plate 1, and the maintenance liquid is transported to the inner cavity of the hose 407 through the arranged water pump 8.

[0039] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, a push rod 9 is fixedly installed at one end of the supporting plate 1 away from the adjustable spraying mechanism 4, and universal wheels 10 are also fixedly installed at the four corners of the bottom of the supporting plate 1, so as to facilitate pushing the maintenance spraying device to the road section that needs maintenance.

[0040] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the first baffle 503 and the second baffle 504 are both made of a resin material with good flexibility, and the first baffle 503 and the second baffle 504 are of the same size, which improves the use stability of the first baffle 503 and the second baffle 504.

[0041] Specifically, when the asphalt pavement maintenance spraying device is used: first, the maintenance liquid is sent into the inner cavity of the material box 1 through the provided water inlet 6, and then the output end of the driving stirring shaft 301 is started, and the stirring blade 302 is driven to rotate by driving the stirring shaft 301, so that the maintenance liquid in the inner cavity of the material box 2 is stirred evenly;

[0042] Then, the maintenance spraying device is pushed to the road section to be maintained by using the push rod 9 and the universal wheel 10 in cooperation with each other;

[0043] Then, the length of the spraying device is adjusted according to the width of the road surface. When the telescopic end of the electric telescopic rod 406 is extended, the intersections of the scissor-type connecting rod group 405 are moved away from each other, and at the same time, the short tube 409 and the hose 407 installed below the scissor-type connecting rod group 405 are driven to be on the same horizontal line. When the telescopic end of the electric telescopic rod 406 is retracted, the intersections of the scissor-type connecting rod group 405 are moved closer to each other, and at the same time, an angle is generated between the short tube 409 and the hose 407 installed below the scissor-type connecting rod group 405. Evenly distributed nozzles 408 are also installed below the short tube 409, which can adapt to roads of different widths while ensuring uniformity of spraying coverage, thereby avoiding the occurrence of missed spraying.

[0044] When the scissor-type connecting rod group 405 is extended or contracted, the sliding rod 402 is driven to slide along the inner wall of the slide plate 401, thereby improving the installation stability of the adjustable spraying mechanism 4;

[0045] By manually toggling the angle connector 502, the inclination angles of the first baffle 503 and the second baffle 504 are adjusted, thereby adjusting the edge line position of the spraying range. When the scissor-type connecting rod group 405 is extended or contracted, the first baffle 503 and the second baffle 504 slide against each other, thereby changing the length of the baffles to avoid gaps between the baffles, avoiding the need to stick the markings with tape before construction and then tearing them off after construction, which wastes time, and spraying the road edge more evenly.

[0046] After the length of the spraying device is adjusted, the water pump 8 is turned on to transport the maintenance liquid in the inner cavity of the material box 2 to the inner cavities of the short tube 409 and the hose 407, and then the road surface is sprayed and maintained through the provided nozzle 408.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
