[0032] A floating cleaning mechanism 4 is provided at the right end of the mobile frame 1. The floating cleaning mechanism 4 includes a drive assembly 41 and a floating cleaning assembly 42. The drive assembly 41 is installed at the right end of the mobile frame 1, and the output end of the drive assembly 41 is equipped with a floating cleaning assembly 42 for cleaning the crevices before filling the crevices.

[0033] A monitoring device 5 for monitoring road conditions is installed on the right end of the mobile frame 1.

[0034] In this invention, road repair material is placed into the feeding mechanism 2, the mobile frame 1 travels along the road, and the monitoring mechanism 5 monitors whether there are potholes or cracks on the road surface. When the mobile frame 1 moves to the road surface that needs repair, the floating cleaning component 42 moves down into the pothole or crack. The floating cleaning component 42, with its floating design, fits into all parts of the pothole or crack to clean the dirt on the surface of the pothole or crack, thereby increasing the adhesion between the repair material and the pothole or crack. Then, the repair material is injected into the adjustable repair mechanism 3 through the feeding mechanism 2, and the discharge width of the adjustable repair mechanism 3 is changed according to the size of the road damage to increase the utilization rate of the repair material.

[0035] Please see Figure 3 The drive assembly 41 includes a fixed support plate 411, a second motor 412, a transmission gear 413, and drive columns 414. The fixed support plate 411 is fixedly installed on the right end of the mobile frame 1. Multiple drive columns 414 are rotatably connected to the fixed support plate 411 through bearings. A transmission gear 413 is fixedly installed on the upper end of each drive column 414. Multiple rows of drive columns 414 are arranged at equal intervals in the left-right direction, and at least two drive columns 414 are arranged in each row in the front-back direction. Adjacent transmission gears 413 are meshed with each other. The second motor 412 is fixedly installed on the fixed support plate 411, and the output end of the second motor 412 is fixedly connected to any one of the transmission gears 413.

[0036] The floating cleaning assembly 42 includes a lifting support plate 421, a second push rod 422, an upper sliding sleeve 423, a lower sliding sleeve 424, a brush head 425, and a spring 426. Two second push rods 422 are symmetrically fixedly installed on the front and rear sides of the right end of the mobile frame 1. The output ends of the second push rods 422 are fixedly connected to the lifting support plate 421.

The brush head 425 is fixedly installed at the lower end of the lower sliding sleeve 424.

[0037] In this invention, the second motor 412 drives the transmission gear 413 to rotate, and under the transmission action of the transmission gear 413, all drive columns 414 rotate. The drive columns 414 then drive the brush head 425 to rotate synchronously. At this time, the second push rod 422 controls the lifting support plate 421 to move down, so that the brush head 425 cleans the inner wall of the pit. With the cooperation of the spring 426, all brush heads 425 abut against the surface of the pit, so that this invention can be applied to cleaning operations of different pits and crevices, and the position of the drive component 41 remains unchanged, effectively increasing the stability of the equipment.

[0038] A fan 6 is also fixedly installed at the right end of the mobile frame 1. The air outlet of the fan 6 is fixedly connected to the lifting support plate 421, and the air outlet is set downward. While the brush head 425 cleans the pit, the fan 6 blows air downward to blow out debris, dust and other things from the pit, thereby increasing the fixing effect of the repair material.

[0039] Please see Figure 2 and Figure 4 The adjustable seam repair mechanism 3 includes a first push rod 31, a fixed plate 32, a sliding plate 33, a top plate 34, and an adjustment assembly.

Two sliding plates 33 are symmetrically arranged front and back, and the left and right ends of each sliding plate 33 are limited and slidably connected to the left and right fixed plates 32 on the left and right sides. With the top view as the orientation, the fixed plate 32 and the sliding plate 33 form a rectangular structure. One end of the top plate 34 is fixedly connected to one side of the fixed plate 32, and the other end of the top plate 34 is limited and slidably connected to the other side of the fixed plate 32. The length of the top plate 34 is the same as the spacing between the fixed plates 32, forming a closed shield on the upper side of the rectangular structure. An adjustment assembly for adjusting the spacing between the sliding plates 33 is provided on both fixed plates 32.

[0040] The pitch adjustment assembly includes a drive gear 35, a driven rack 36, and a first motor 37. The drive gear 35 is rotatably connected to the fixed plate 32 via bearings.

The two ends of the discharge pipe 23 are fixedly connected to the discharge end of the pump 22 and the top plate 34, respectively.

[0042] In this invention, the first motor 37 drives the drive gear 35 to rotate, causing the two driven racks 36 to drive the two translation plates 33 to move synchronously in opposite directions, thereby adjusting the distance between the translation plates 33. This allows the box formed by the fixed plate 32, translation plates 33, and top plate 34 to match the size of the pothole to be repaired. Then, the first push rod 31 moves the fixed plate 32 downward, so that the lower ends of the fixed plate 32 and translation plates 33 are in contact with the ground. The pump 22 feeds the repair material from the material cylinder 21 into the inside of the fixed plate 32, translation plates 33, and top plate 34, filling the pothole with the repair material. As the moving frame 1 moves, the repair material is scraped flat, thereby effectively increasing the utilization rate of the repair material.
