The same mixing barrel 7 has a cover 8 fixedly installed on the top of the mixing barrel 7 by bolts, a stirring rod 9 is rotatably installed on the bottom of the cover 8, a first servo motor is fixedly installed on the top of the cover 8, and its output shaft is fixedly connected to the top of the stirring rod 9, a drainage bucket 10 is fixedly installed on the supporting platform 5, the drainage bucket 10 is located below the mixing barrel 7, a discharge bucket 11 is provided below the drainage bucket 10, a transmission rod 12 is rotatably installed on the supporting platform 5, the transmission rod 12 is fixedly connected to the discharge bucket 11 through a connecting arm 13, and a second servo motor is fixedly installed on the top of the supporting platform 5, and its output shaft is fixedly connected to the top of the transmission rod 12.

[0024] In the above method, in order to provide movable limit for the movable plate 3 so that its movable range can be adjusted according to the width of the damaged road surface, a crossbeam 14 is fixedly installed on the top of the movable frame 1, and a connecting frame 15 is fixedly installed on the bottom thereof. A bidirectional screw 16 is rotatably installed in the connecting frame 15, and two blocking plates 17 are threadedly installed on the bidirectional screw 16. The two blocking plates 17 are respectively located on both sides of the movable plate 3. In addition, a third servo motor is fixedly installed on one side of the connecting frame 15, and its output shaft is fixedly connected to one end of the bidirectional screw 16. A scale is fixedly installed in the connecting frame 15, and the scale passes through the two blocking plates 17 and is slidably connected to the two blocking plates 17. The design of the scale makes it convenient for people to adjust the blocking plates 17 to a rough position.

[0025] In this embodiment, a feeding pipe is fixedly installed on the top of the cover 8 , a discharging pipe is fixedly installed on the bottom of the mixing barrel 7 , a material valve is provided on the discharging pipe, and the discharging pipe is located above the drainage bucket 10 .

[0026] The working principle of the municipal road maintenance and repair device provided by the utility model is as follows:

[0027] When the damaged road surface needs to be repaired, various concrete raw materials are first put into the mixing barrel 7, and then the first servo motor is started, and its output shaft drives the mixing rod 9 to rotate, so as to mix the concrete. After the concrete is mixed, the mobile frame 1 is pushed to push the discharge hopper 11 above the damaged road surface;

[0028] Then, adjust the positions of the two blocking plates 17 according to the width of the damaged part. When adjusting, measure the width of the damaged part first, and then start the third servo motor in the positive direction, and its output shaft drives the bidirectional screw 16 to rotate, and the two blocking plates 17 move away from each other. At this time, observe the position of the blocking plates 17 on the scale. When they move to the approximate position, turn off the third servo motor. At this time, the limiting of the two sides of the moving plate 3 is completed, and then start the output shaft of the electric push rod 4 to extend. When the moving plate 3 contacts the blocking plate 17 on one side, start the output shaft of the electric push rod 4 to retract. When the moving plate 3 contacts the blocking plate 17 on the other side, start the output shaft of the electric push rod 4 to extend again. In this way, the moving plate 3 moves back and forth left and right, and the supporting platform 5 and the discharge hopper 11 also move back and forth left and right;

[0029] After that, the material valve on the discharge pipe is opened, and the mixed concrete enters the discharge hopper 11 through the drainage hopper 10, and finally flows into the damaged road surface. During the inflow process, the discharge hopper 11 continuously moves left and right, so that the concrete can flow evenly into the damaged road surface, improving the uniformity of concrete distribution until the concrete filling is completed;

[0030] After the repair is completed, the second servo motor is started, and its output shaft is used to drive the transmission rod 12 to rotate 180 degrees, so that the discharge hopper 11 is rotated to the bottom of the supporting platform 5 so that it does not protrude too much, so as to place and store the entire mobile rack 1.

[0031] Compared with the related art, the municipal pavement maintenance and repair device provided by the utility model has the following beneficial effects:

[0032] The utility model provides a municipal pavement maintenance and repair device, which can rotate the discharge hopper 11 located below the bearing platform 5 through the transmission rod 12, so that it protrudes from the bearing platform 5, so that there is no obstruction between the staff's sight and the discharge hopper 11, and the discharge hopper 11 can be moved to a designated position at one time, thereby improving the convenience. In addition, in the process of discharging concrete, the reciprocating extension and retraction of the output shaft of the electric push rod 4 can make the discharge hopper 11 form a reciprocating movable discharge, thereby ensuring that the concrete can be filled evenly.
