[0022] Embodiment 1

[0023] As Figure 1 shown:

[0024] A road maintenance crack filling device includes a mobile vehicle body 1 and an asphalt tank main body 2 installed on the upper surface of the mobile vehicle body 1 by bolts.

[0025] In this implementation: The existing device {publication (announcement) number}: CN215164507U discloses a road maintenance crack filling device. To solve the technical problems existing in this prior art, as disclosed in the background art above, "Although the above design is convenient for fully stirring the raw materials in the raw material barrel and avoiding uneven heating of the raw materials during use, when using a road maintenance crack filling device, due to the irregular cracks on the road, it is difficult to flexibly adjust the crack filling device to quickly correspond to the cracks. The flexibility of the device in use is poor. At the same time, after crack filling is completed, the temperature of the discharge pipe is likely to decrease, and the asphalt raw materials inside the discharge pipe solidify, resulting in pipe blockage, affecting subsequent use and reducing the use effect of the device." In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a crack filling component 3 and a locking component 4 are added to this application document.

[0026] In this product, a movable power source is placed on the mobile vehicle body 1 for the electrical equipment involved.

[0027] Furthermore:

[0028] As Figures 1-4 shown:

[0029] A crack filling assembly 3 is installed on the moving vehicle body 1. The crack filling assembly 3 includes a water tank 304 fixedly installed on the upper surface of the moving vehicle body 1 by bolts, a water pipe 305 connected and fixed to the bottom of one side of the surface of the water tank 304, and a centrifugal pump 301 fixedly installed on the upper surface of the moving vehicle body 1 through a mounting seat. A first connecting hose 302 is fixed to the input end of the centrifugal pump 301. A connecting pipe is connected and fixed to the surface of the asphalt tank body 2, and a second control valve 307 is installed in the connecting pipe. One end of the water pipe 305 away from the water tank 304 is fixedly installed with a first control valve 306. One end of the first connecting hose 302 is installed and fixed at one end of the connecting pipe of the asphalt tank body 2 by a detachable installation method. A second connecting hose 303 is fixed to the output end of the centrifugal pump 301, and the other end of the second connecting hose 303 is fixedly installed with a crack filling gun body 308.

[0030] In this implementation: When using this road maintenance crack filling device, connect the centrifugal pump 301 to a mobile power source (not shown in the figure) to supply power to the centrifugal pump 301. Through the operation of the centrifugal pump 301, the asphalt inside the asphalt tank body 2 is discharged into the second connecting hose 303 through the first connecting hose 302, and then discharged into the crack filling gun body 308 through the second connecting hose 303. During this process, by holding the crack filling gun body 308, it is convenient to flexibly adjust the asphalt discharge position, so that the port of the crack filling gun body 308 corresponds to the road crack. The asphalt is discharged through the crack filling gun body 308 and into the road crack for repair. After the repair of the road crack is completed, then remove one end of the first connecting hose 302 from the connecting pipe of the asphalt tank body 2, and at the same time rotate the second control valve 307 to block the asphalt tank body 2. Subsequently, install one end of the first connecting hose 302 at one end of the water pipe 305, and open the first control valve 306. At this time, start the centrifugal pump 301, discharge the water inside the water tank 304 through the water pipe 305 into the first connecting hose 302, and then discharge it along the centrifugal pump 301 into the second connecting hose 303, and discharge it through the crack filling gun body 308 on the second connecting hose 303. As the water is continuously discharged, the remaining asphalt is also discharged. Through the above operations, it is possible to flexibly adjust the quick correspondence between the crack filling device and the crack for irregular cracks. This mechanism has higher flexibility, is relatively more lightweight and convenient for the movement of the moving vehicle body 1, and at the same time can clean the residual asphalt in the pipe body, avoiding the situation that the asphalt inside the pipe body solidifies due to temperature drop when the device is not used for a long time, and avoiding the blockage of the pipe body, improving the use effect of the device.

[0031] Furthermore;

[0032] In an alternative embodiment, support frames 309 are provided on both sides of the caulking gun body 308. Connecting rods are fixed between the caulking gun body 308 and the support frames 309. Universal wheels 315 are fixedly installed at the bottom ends of the support frames 309 by bolts, and grips 310 are fixedly installed at the top ends of the two groups of support frames 309.

[0033] In this embodiment: During the repair operation, hold the grip 310 by hand, and then support the caulking gun body 308 through the support frame 309. At the same time, the universal wheels 315 can move flexibly on the ground. Through this operation, it is not necessary to always hold the caulking gun body 308 by hand, which may cause arm fatigue.

[0034] Furthermore;

[0035] In an alternative embodiment, the support frame 309 is designed with a hollow frame structure, and the caulking gun body 308 is designed with an inclined structure.

[0036] In this embodiment: The support frame 309 is designed with a hollow structure to reduce the overall gravity and improve the flexibility. The caulking gun body 308 is designed with an inclined structure. Compared with the caulking gun body 308 being perpendicular to the ground, it is possible to better and more intuitively observe the accurate alignment between the drainage port of the caulking gun body 308 and the crack.

[0037] Furthermore;

[0038] In an alternative embodiment, a mounting plate 311 is fixedly installed at the bottom of the inner cavity of the support frame 309. A rotating rod 312 is rotatably connected between the two mounting plates 311 through bearings. A scraper 314 is fixed on the surface of the rotating rod 312. Return torsion springs 313 are wound around both ends of the rotating rod 312, and both ends of the return torsion springs 313 are fixedly connected to the mounting plate 311 and the rotating rod 312 respectively.

[0039] In this embodiment: As the grip 310 is pushed to drive the movement of the support frame 309, the scraper 314 is driven to move accordingly. With the cooperation of the rotating rod 312 and the return torsion springs 313, the bottom end of the scraper 314 is closely attached to the ground, so that the asphalt discharged into the crack can be scraped flat, thereby improving the aesthetics of the caulking and avoiding unevenness on the road surface.

[0040] Furthermore;

[0041] In an alternative embodiment, a locking assembly 4 is mounted on the moving vehicle body 1. The locking assembly 4 includes a jack 405 formed on the surface of the moving vehicle body 1 and adapted to the support frame 309. One side of the moving vehicle body 1 is rotatably connected to an adjusting screw rod 402 through a bearing. A rectangular plate 401 is threadedly connected to the surface of the adjusting screw rod 402. Symmetrically arranged clamping blocks 404 are fixed on the surface of the rectangular plate 401. The clamping blocks 404 correspond to the internal cavity of the support frame 309. Symmetrically arranged telescopic rods 403 are fixed between the rectangular plate 401 and the moving vehicle body 1.

[0042] In this implementation: The support frame 309 is driven to insert the universal wheels 315 into the jack 405 opened on the moving vehicle body 1. At this time, the mounting plate 311 temporarily blocks the support frame 309. Then, by rotating the adjusting screw rod 402, the rectangular plate 401 is driven to move. The clamping block 404 is driven to move by the rectangular plate 401 until the clamping block 404 moves into the frame body of the support frame 309 to limit and lock the support frame 309. While the rectangular plate 401 moves, the telescopic rod 403 is driven to be compressed. Through the setting of the telescopic rod 403, the rectangular plate 401 can be limited, making the movement of the rectangular plate 401 more stable. Through this operation, the support frame 309 and the caulking gun body 308 can be integrally fixed on the moving vehicle body 1, avoiding the situation of observing whether the overall components of the caulking gun body 308 and the support frame 309 fall off during the movement of the moving vehicle body 1, and further improving the use effect of the device.

[0043] Working principle and usage process of the present utility model: When using this road maintenance crack sealer, connect the centrifugal pump 301 to a mobile power source (not shown in the figure) to supply power to the centrifugal pump 301. Through the operation of the centrifugal pump 301, the asphalt in the asphalt tank main body 2 is discharged into the connecting hose two 303 through the connecting hose one 302, and then discharged into the crack filling gun body 308 through the connecting hose two 303. During this process, by holding the crack filling gun body 308 by hand, it is convenient to flexibly adjust the asphalt discharge position, so that the port of the crack filling gun body 308 corresponds to the road crack. The asphalt is discharged through the crack filling gun body 308 and into the road crack for repair operation. During this process, hold the grip 310, and then support the crack filling gun body 308 through the support frame 309. At the same time, the universal wheels 315 can move flexibly on the ground. Through this operation, there is no need to hold the crack filling gun body 308 all the time, which may cause arm fatigue. At the same time, the support frame 309 is designed with a hollow structure, which reduces the overall gravity and improves the flexibility. The crack filling gun body 308 is designed with an inclined structure, so that compared with the crack filling gun body 308 being perpendicular to the ground, it is easier to visually observe the accurate correspondence between the liquid discharge port of the crack filling gun body 308 and the crack. As the push grip 310 is pushed to drive the movement of the support frame 309, the scraper 314 is driven to move. With the cooperation of the rotating rod 312 and the return torsion spring 313, the bottom end of the scraper 314 is closely attached to the ground, so that the asphalt discharged into the crack can be scraped flat, improving the aesthetics of the crack filling and avoiding unevenness on the road surface. After the repair of the road crack is completed, one end of the connecting hose one 302 is removed from the connecting pipe of the asphalt tank main body 2, and at the same time, the control valve two 307 is rotated to block the asphalt tank main body 2. Then, one end of the connecting hose one 302 is installed at one end of the water pipe 305, and the control valve one 306 is opened. At this time, the centrifugal pump 301 is started, and the water in the water tank 304 is discharged into the connecting hose one 302 through the water pipe 305, and then discharged into the connecting hose two 303 along the centrifugal pump 301, and discharged through the crack filling gun body 308 on the connecting hose two 303. As the water is continuously discharged, the residual asphalt is also discharged. Through the above operations, the crack sealer can be flexibly adjusted to quickly correspond to irregular cracks. This mechanism has higher flexibility, is relatively lighter and more convenient to move for the mobile vehicle body 1, and can clean the residual asphalt in the pipe body, avoiding the solidification of the asphalt in the pipe body due to temperature drop when the device is not used for a long time, and avoiding pipe blockage, improving the use effect of the device. Subsequently, the support frame 309 driving the universal wheels 315 is inserted into the jack 405 opened on the mobile vehicle body 1. At this time, the mounting plate 311 temporarily blocks the support frame 309. Then, by rotating the adjusting screw 402, the rectangular plate 401 is driven to move, and the rectangular plate 401 drives the block 404 to move until the block 404 moves into the frame body of the support frame 309.To limit and lock the support frame 309, while the rectangular plate 401 moves, it drives the telescopic rod 403 to be compressed. Through the setting of the telescopic rod 403, the rectangular plate 401 can be limited, making the movement of the rectangular plate 401 more stable. Through this operation, the support frame 309 and the caulking gun body 308 can be integrally fixed on the moving vehicle body 1, avoiding observing whether the overall components of the caulking gun body 308 and the support frame 309 fall off during the movement of the moving vehicle body 1, and further improving the use effect of the device.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
