[0052] When the concrete on the concrete pavement needs to be smoothed, the device is connected to the motor vehicle through the mounting plate 8, and the device is above the concrete on the concrete pavement that needs to be smoothed.

[0053] The two first electric telescopic rods 11 are started at the same time, the piston rod of the first electric telescopic rod 11 pushes the two baffles 2 to move downwards, and the two baffles 2 move downwards to drive the scraper 1 to move downwards until the bottom of the two baffles 2 and the scraper 1 is in contact with the upper surface of the concrete on the concrete pavement that needs to be smoothed.

[0054] At this time, the device is moved by the motor vehicle, and the scraper 1 moves towards the mounting plate 8.

[0055] When the scraper 1 moves on the upper surface of the concrete on the concrete pavement that needs to be smoothed, the concrete on the concrete pavement is smoothed by the scraper 1, and when the concrete between the scraper 1 and the two baffles 2 is too much, the excess concrete can enter the collection groove 20 on the top of the scraper 1 through the inclined plate 19, and the cooperation of the scraper 1, the inclined plate 19 and the two baffles 2 can collect the excess concrete between the scraper 1 and the two baffles 2 into the collection groove 20, so that the excess concrete is not squeezed into other parts during the smoothing process, and the excess concrete between the scraper 1 and the two baffles 2 is uniformly collected into the collection groove 20 for temporary storage, which facilitates the filling of the area where the concrete is insufficient.
