Rain shields 3 are rotatably connected to both sides in the width direction of the water tank 2 through hinges. A rainproof cloth 4 is adhesively bonded at the gap between the rain shield 3 and the water tank 2. A traction hole 31 is provided on the side of the rain shield 3 away from the hinge. A steel rope can be tied in the traction hole 31, and pulling the steel rope can adjust the turning angle of the rain shield 3. A hook 32 is tied to the side of the steel rope away from the traction hole 31. The hook 32 is provided with a through hole 321 corresponding to the steel rope. An adjusting block 23 is provided on the inner wall of the water tank 2. The hook 32 can be fixed to the adjusting block 23. By arranging the water tank 2 on the top of the driving motor, a certain rain shielding effect is achieved. The rain shields 3 are hingedly installed on both sides in the width direction of the water tank 2 to prevent raindrops from being blown laterally by the wind to the driving motor. The rainproof cloth 4 can block rainwater from flowing in through the gap between the water tank 2 and the rain shield 3. The steel rope can restrain the turning angle of the rain shield 3. When it is sunny, the rain shield 3 is pulled up to enhance the heat dissipation effect of the driving motor. One grooving wheel 131 realizes grooving on the cement pavement after repairing the potholes on the airport, achieving the repair effect.

[0023] Please refer to Figure 1 - Figure 4, in this embodiment, two first fixing hooks 231 are provided on the adjusting block 23, and the hook parts of the first fixing hooks 231 are arranged oppositely. Two second fixing hooks 232 are provided outside the two first fixing hooks 231 on the adjusting block 23, and the hook parts of the second fixing hooks 232 are arranged oppositely. The hook 32 can be hooked on the first fixing hook 231, and the hook 32 can be hooked on the second fixing hook 232. Through the cooperation of the hook 32 with the first fixing hook 231 and the second fixing hook 232, the gear adjustment function of the rain shield 3 is realized. The structure is simple and the operation is convenient. When the hook 32 is hooked on the first fixing hook 231, the steel rope contacts the side wall of the water tank 2. A breaking wall hole 24 corresponding to the steel rope is provided on the side wall of the water tank 2. The breaking wall hole 24 can limit the steel rope. The breaking wall hole 24 prevents the steel rope from slipping off the water tank 2, causing an impact on the rain shield 3 and scaring the staff into a dangerous accident. A fixing plate 22 protruding upward is provided at the bottom of the water tank 2. The fixing plate 22 is perpendicular to the moving direction of the engraving machine 1. A through-flow hole 221 is provided on the fixing plate 22. The through-flow hole 221 is close to the bottom of the water tank 2. A universal adjustable cooling pipe 25 is installed at the bottom of the water tank 2. The universal adjustable cooling pipe 25 is connected to the inside of the water tank 2. The universal adjustable cooling pipe 25 includes a water outlet, and the water outlet points to the engraving wheel 131. The fixing plate 22 prevents the cooling water from shaking violently in the water tank 2 when the engraving machine 1 moves, causing the device to swing. The through-flow hole 221 can make the cooling water separated by the fixing plate 22 flow through each other. The universal adjustable cooling pipe 25 has the ability to switch and adjust the direction to cool the engraving wheel 131.

[0024] Please refer to Figure 2 - Figure 5, in this embodiment, a lifting part 5 is provided on the side of the grooving machine 1 away from the armrest 11. The lifting part 5 includes a lifting block 51. A convex block 52 protrudes outward on the side of the lifting block 51 away from the armrest 11. A traction handle 53 is rotatably connected to the convex block 52. The traction handle 53 is of a U-shaped structure. Through the U-shaped traction handle 53, it can be hooked and matched with the traction column of the airport tractor. The roller 12 has a relatively low height, and the side of the device hung on the traction column close to the lifting part 5 is lifted, preventing the grooving wheel 131 from being damaged when the device is dragged by the airport tractor. Rotating holes 531 are provided on both sides in the length direction of the traction handle 53, and rotating shafts 521 are provided on both sides of the convex block 52 along the width direction of the grooving machine 1. The rotating holes 531 are in shaft-hole cooperation with the rotating shafts 521, enabling the traction handle 53 to rotate and retract towards the water tank 2 through the cooperation of the rotating holes 531 and the rotating shafts 521, preventing the traction handle 53 from being dragged on the ground when the device is working. A jacking hole 512 is provided at the top of the lifting block 51 corresponding to the center line in the length direction of the traction handle 53. A limiting groove 511 corresponding to the traction handle 53 is provided on the lifting block 51. The traction handle 53 can be placed in the limiting groove 511. An anti-disengagement handle 54 can be inserted into the jacking hole 512. By inserting the traction handle 53 into the jacking hole 512, it prevents the traction handle 53 from moving due to shaking. The traction handle 53 is placed in the limiting groove 511, making the limiting groove 511 more stable and reducing the noise generated by collisions.

[0025] When working, first ensure that the positions of the potholes on the airport road surface are filled and the cement laid in the potholes has solidified. The operator pulls out the anti-disengagement handle 54 from the jacking hole 512, pulls up the traction handle 53 and slews it on the traction column of the airport tractor, lifting the grooving wheel 131 off the ground. Then, the device is towed to the water replenishment station to fill the water tank 2. Subsequently, the airport tractor is driven to the place where pothole repair is required. The traction handle 53 is pulled to lift it up, aligning the grooving wheel 131 with the position where grooving is needed. Another operator starts the drive motor and simultaneously opens the universal adjustable cooling pipe 25 to make the grooving wheel 131 perform grooving, causing the grooving wheel 131 to partially sink into the ground. At this time, the four rollers 12 contact the ground. Then, the traction handle 53 is retracted towards the position of the water tank 2, placing the traction handle 53 in the limiting groove 511, and inserting the anti-disengagement handle 54. Finally, the operator pushes the device along the route where grooving is required for grooving.

[0026] Through the above steps, the water tank 2 is arranged on the top of the driving motor to achieve a certain rain shielding effect. The rain shielding plates 3 are hingedly installed on both sides in the width direction of the water tank 2 to prevent raindrops from being blown laterally by the wind to the driving motor. The rain shielding cloth 4 can block rainwater from flowing in through the gap between the water tank 2 and the rain shielding plates 3. The steel rope can restrain the flipping angle of the rain shielding plates 3. When it is sunny, the rain shielding plates 3 are pulled up to enhance the heat dissipation effect of the driving motor. A grooving wheel 131 is used to groove the cement road surface after the airport potholes are repaired to achieve the repair effect, so as to solve the problems that in the prior art, the device uses a blade group to groove the road surface, which is not suitable for local grooving of airport pothole repair, and the driving mechanism is exposed to the open air environment, and the driving mechanism is easily damaged by water ingress.
