[0027] In addition, when the double-head motor is working, the two grouting nozzles can move inward or outward at the same time. When the crack is deep and narrow, the staff can adjust the distance between the two grouting nozzles to the longest, so that there is a period of time between spraying on both sides, which is conducive to the first spraying of mortar entering the bottom of the crack; when the crack is slightly curved, the staff can adjust the distance between the two grouting nozzles to the shortest, which is conducive to the mortar entering the curved crack.

[0028] 3. When mortar is present on the top of the conical movable cover, the conical movable cover can automatically move downward under the gravity of the mortar; when the position sensor detects that the staff has left the equipment, the control panel controls the buzzer to work, which can prompt the staff to turn off the air pump and mortar suction pump;

[0029] In addition, when the road crack construction is completed and the position sensor detects that the staff has left the equipment, the control panel will also control the buzzer to work, which can remind the staff to clean the residual mortar in the mortar storage part, movable support part and grouting construction part in time; when the mortar storage part, movable support part and grouting construction part are cleaned, the conical movable cover moves upward under the action of coil spring B. At this time, the detection button is released, and even if the position sensor detects that the staff has left the equipment, the control panel will not control the buzzer to work.

[0071] 5) When the construction is completed and the buzzer 7011 is working, the staff will promptly clean the remaining mortar in the mortar storage part 400, the movable support part 500 and the grouting construction part 600.

[0072] The specific usage and function of this embodiment are as follows:

[0073] When the present invention is used, first pour the mortar for repairing the cracks into the mortar storage bucket 401, and then adjust the distance between the two grouting nozzles 607 appropriately through the control panel 701 according to the crack conditions of the road; when the cracks are deep and narrow, the staff can adjust the distance between the two grouting nozzles 607 to the longest, so that there is a period of time between the spraying on both sides, which is conducive to the mortar sprayed for the first time to enter the bottom of the crack; when the cracks are slightly curved, the staff can adjust the distance between the two grouting nozzles 607 to the shortest, which is conducive to the mortar entering the curved part. According to the actual situation of the cracks, the working gear of the mortar suction pump 402 is appropriately adjusted through the control panel 701, and then the moving speed of the vehicle body 100 is appropriately adjusted according to the actual situation of the cracks; the air pump 301 and the mortar suction pump 402 are started through the control panel 701, and the road crack repair is completed; when the air pump 301 is working, the external air enters the air pump 301, and then is ejected through the cleaning nozzle 303, which plays a pre-cleaning role on the cracks in the road surface, which is conducive to improving the crack repair effect; the setting of the two filters 205 has a great effect on the cracks. The dust in the cracks plays a blocking role, ensuring that the dust in the cracks will not float into the air; the setting of the two separation partitions 204 plays a blocking and separating role for the dust blocked by the two filters 205, ensuring that the dust at the two filters 205 basically does not enter the cracks; the setting of the two coil springs A207 ensures that the rectangular protective cover 202 can always be in contact with the road surface, so that almost all the air in the rectangular protective cover 202 is discharged through the two filters 205; when the construction is not completed and the buzzer 7011 is working, the staff will promptly turn on the air pump 301 and the sand The slurry suction pump 402 is turned off; when the construction is completed and the buzzer 7011 is working, the staff will promptly clean the residual mortar in the mortar storage part 400, the movable support part 500 and the grouting construction part 600; when the mortar storage part 400, the movable support part 500 and the grouting construction part 600 are cleaned, the conical movable cover 501 moves upward under the action of the coil spring B503. At this time, the detection button 702 is released, and even if the position sensor 703 detects that the staff has left the equipment, the control panel 701 will not control the buzzer 7011 to work.
