The milling device 7 comprises a milling motor 21, a milling holder 20, a rotation-revolution mechanism, a milling cutter disc 23, a milling cutter 28, a cutter holder and a blade. The milling frame 20 is connected with a lifting device, the milling motor 21 is arranged in the center of the milling frame 20, the milling cutter disc 23 is rotatably arranged at the bottom of the milling frame 20 through a rotary mechanism 26, and under the action of the rotary mechanism 26, the milling cutter disc 23 can rotate on the milling frame 20 and is connected with a main shaft of the milling motor 21 through a connecting shaft 33. The rotation-revolution mechanism is mounted on the milling frame 20, and the milling cutters 28 are provided in plurality and rotatably mounted on the bottom of the milling cutter disc 23 in a uniformly distributed manner in the circumferential direction, and the milling cutters 28 are connected to the rotation-revolution mechanism so as to be capable of rotating while revolving with the milling cutter disc 23. The blade holder is mounted at the bottom of the milling cutter disc 23 and the blade is mounted on the blade holder. As shown in fig. 8 and 9, the insert seats comprise a long insert seat 29 and a short insert seat 31, and the insert comprises a first insert 30 and a second insert 32. The long knife rest 29 and the short knife rest 31 are installed by screws, so that the long knife rest 29 and the short knife rest are convenient to detach and install.

During milling, the water pump 19 works to convey the water in the water tank 6 into the annular water pipe 16, and finally the water mist is sprayed out from the nozzle 17, so that the water mist is combined with sand and stone fragments generated by ground milling to avoid spreading around.

The lifting device comprises an oil cylinder 3, a pump station 4, a guide post 18 and a linear bearing 34. The oil cylinder 3, the guide post 18 and the linear bearing 34 are all installed on the installation frame 2, a piston rod of the oil cylinder 3 is connected with the lifting lug 22 on the milling frame 20, the pump station 4 controls the oil cylinder 3 to stretch and retract, the bottom end of the guide post 18 is connected with the milling frame 20, and the post body is in sliding connection with the linear bearing 34. When the pump station 4 works, the oil cylinder 3 can be driven to stretch out and draw back, so that the milling device is driven to wholly ascend or descend.

The utility model also comprises a power unit 14, a steering unit, a cruising device 5, a control unit 12 and a seat 10. The power device 14 and the steering device are arranged at the bottom of the vehicle body 1, and the power device 14 drives the rear wheels 9 to rotate positively and negatively, so that the whole device can move forwards and backwards. The steering device comprises a steering wheel 11 and a steering mechanism driven by the steering wheel 11, wherein the steering mechanism is connected with the front wheels 8, so that the front wheels 8 are driven to rotate left and right, and the left and right turns of the whole device are realized. In the present utility model, the power device 14 may be a combination of a fuel engine and a speed reducer according to a driving mode, and the cruising device 5 may be an oil tank or an electric motor, and the cruising device 5 may be a power battery. It is to be noted that, whichever mode is adopted, the device adopts the storage battery to supply power for the electric equipment, thereby meeting the electric energy consumption required by the operation.

The control device 12 is mounted on the top front end of the vehicle body 1, and has a center console, an accelerator pedal, a brake pedal, and an instrument panel and control buttons provided on the center console, and is capable of receiving operation instructions to control the operation of the entire device. The seat 10 is mounted on the water tank 6 behind the control device 12, and the cruising device 5 is mounted on the mounting frame 2. The walking of the whole device can be realized through self power, compared with the existing manual-driven repair vehicle, the device has stronger flexibility and maneuverability, enlarges the operation range and is beneficial to improving the operation efficiency. In order to accurately position the ground pothole 200, a camera is further installed at the bottom of the vehicle body 1, and a screen is arranged on the center console, so that a worker can observe the ground condition conveniently to judge the position of the ground pothole 200, and accurate positioning is achieved. The above devices are all of the prior art, and are not described in detail.

As shown in fig. 10, when the depression 200 appears in the ground 100, the apparatus is moved to the depression 200. As shown in fig. 11, after the operator aligns the milling device with the depression 200, the device is started, and the lifting device controls the milling device to descend to mill the ground 100 around the depression 200, so as to obtain a circular groove 300 with a milling height set at a set value, typically 8cm. After milling, the lifting device is reset and moved aside to fully expose the circular groove 300. As shown in fig. 12, a prefabricated repair plate 400 having a shape matching that of the circular groove 300 is placed in the circular groove 300, and the surface of the repair plate 400 is flush with the ground 100. Since the circular groove 300 is slightly larger than the repair plate 400, a gap 500 is formed therebetween, and quick-setting cement is injected into the gap 500 by manual operation to finish the final repair. It can be seen that in this way, the time required for casting cement in situ can be reduced, and the requirements of on-site repair and ready-to-use can be met. The device has the capability of walking on the ground, so that the trailer can be towed at the tail of the device, and the prefabricated repair plates 400 are uniformly placed on the trailer, thereby achieving the purpose of continuous operation for a long time. The weight of the single repair plate 400 is about 40kg, so that the whole repair work can be completed by only one person in actual operation, and the labor cost is reduced.
