It is connected to the movable claw 14, and a connecting port 13 is also provided on the side of the movable claw 14 away from the connecting port 13 on the fixed plate 16. The excavator body 8 first moves the claw assembly between the two connecting pins 27, first makes the connecting port 13 on the fixed plate 16 stuck on the connecting pin 27 close to the collection box 21, and then the connecting cylinder 15 pushes the movable claw 14 to rotate, so that the connecting port 13 on the movable claw 14 is stuck on the other connecting pin 27, and then the claw assembly is connected to the collection box 21.

[0038] When the present invention is in use, the excavator body 8 first moves the claw assembly to between the two connecting pins 27, so that the two connecting ports 13 respectively clamp the two connecting pins 27, so that the claw assembly is connected to the collection box 21, and the cleaning mechanism 1 and the collection box 21 are rotatably connected to the end of the mechanical arm of the excavator body 8 through the reversing connection assembly 3. The device can be directly transported through the excavator body 8, and there is no need to carry the device to the engineering vehicle for transportation, which saves the time of carrying the cleaning device. The cleaning mechanism 1 and the collection box 21 can be rotated on the excavator body 8 through the reversing connection assembly 3, and the positions of the cleaning mechanism 1 and the collection box 21 can be adjusted as needed without moving the excavator body 8 itself, which is more flexible and convenient to use and saves the time of road repair.
