[0046] The operator pushes the device to the top of the road pit through the walking wheel 11 by the handrail 12, and places the pressing plate 342 and the folding rod 343 in the road pit. Then, concrete is added into the mixing barrel 20 through the feeding port 22, and the servo motor 412 is started.

[0047] Then, the sliding baffle plate 25 opens the discharge port 23, and the concrete in the mixing barrel 20 is discharged into the road pit through the discharge port 23. The rotation of the transmission rod 414 can drive the incomplete gear 431 to rotate, and the teeth of the incomplete gear 431 can drive the rack 432 to move upward, and the upward movement of the rack 432 can drive the pressing plate 342 and the folding rod 343 to move upward and compress the elastic member 33. When the teeth of the incomplete gear 431 are separated from the rack 432, the elastic force of the elastic member 33 pushes the lifting plate 32 downward, realizing the up and down reciprocating motion of the pressing plate 342 and the folding rod 343, thereby realizing the vibration of the concrete.

[0048] The device is pushed to move via the running wheels 11, so that concrete can be filled and vibrated at different positions in the road pit.

[0049] The above concrete pavement repair device can automatically fill concrete into the road pit and automatically vibrate and fill the filled concrete to ensure the repair effect. The process is simple and convenient, avoiding the problem of low labor efficiency and improving construction efficiency. At the same time, the driving mechanism 40 can simultaneously realize the stirring of the mixing barrel 20 and the vibration of the vibration mechanism 30, which can simplify the structure of the concrete pavement repair device and reduce costs.
