The adjusting rod assembly 108 used at this time will close the valve 109. When the guide bar 113 needs to be cleaned, the controller 115 is used to change the output direction of the motor 122 to reverse its output end. At this time, the corresponding stirring plate 120 will also reverse inside the heating cylinder 102. At the same time, the other single-head screw 119 will also drive the one-way The other end of the clutch 202 is reversed, and the other end of the reversed one-way clutch 202 drives one end of the one-way clutch 202 to rotate (due to the characteristics of the one-way clutch 202). When one end of the one-way clutch 202 rotates, the connecting member 204 connected thereto also rotates. At this time, the rotating connecting member 204 drives the winding wheel 205 to rotate with the cooperation of the fixed plate 206. Subsequently, the rotating winding wheel 205 will continuously reel in the connecting rope 215.

[0027] The effect and working principle of the entire mechanism are as follows: In the preparation phase, first connect the controller 115 and the battery 117 with new wires, then connect the heating cartridge 102 and the battery 117 with new wires, and then connect the motor 122 and the controller 115 with new wires. Then, turn on the controller 115 and set various parameters. At the same time, turn on the heating cartridge 102 and set the temperature threshold and heating temperature. Then, open the cartridge cover 103, pour an appropriate amount of repair material into the interior of the heating cartridge 102, and finally close the cartridge cover 103. During the repair phase, when it is necessary to repair the road cracks, the mobile vehicle 101 and the wheeled auxiliary frame 104 are first used to move the entire road crack repair device to the road to be repaired, and then the mobile vehicle 101 and the wheeled auxiliary frame 104 are used to move the entire road crack repair device to the road to be repaired. The mobile vehicle 101 is then paused, and the start button of the heating cylinder 102 is then pressed. The heating cylinder 102 will then heat and melt the repair material inside it. At the same time, the temperature sensor on the heating cylinder 102 will also constantly detect the ambient temperature of the repair material inside it, and transmit the data detected each time to the control board in the heating cylinder 102. At the same time, the controller 115 is used to start the motor 122, and its output end is rotated forward. At this time, the started motor 122, in cooperation with the L-shaped block 123 and the two single-head screws 119, drives the motor 122 to rotate forward. The dynamic stirring plate 120 rotates inside the heating cylinder 102. At this time, the rotating stirring plate 120 can make the repair material inside the heating cylinder 102 evenly heated. At the same time, the rotating single-head screw 119 will also drive the other end of the one-way clutch 202 to rotate under the cooperation of the two sprockets 203, the hole block 201 and the chain (due to the characteristics of the one-way clutch 202, one end of the one-way clutch 202 will not rotate at this time). When the material inside the heating cylinder 102 is heated and melted into a fluid, and the temperature data transmitted by the temperature sensor in the heating cylinder 102 is the same as the temperature threshold set in advance for the heating cylinder 102, the heating cylinder 102 will stop heating. Similarly, when the temperature sensor in the heating cylinder 102 When the temperature data transmitted by the device is lower than the temperature threshold value set in advance by the heating cylinder 102, the heating cylinder 102 will start the heating operation, that is, to ensure that the repair material inside the heating cylinder 102 is always in a fluid state. When the repair material inside the heating cylinder 102 is heated into a fluid material, the road crack repair device continues to be moved, and the perforated plate 106 and the connecting rod 107 are used to cooperate to allow the limit ring 105 to move to the crack and pause, and then manually turn the handle of the adjusting rod assembly 108. The adjusting rod assembly 108 used at this time will drive the valve stem of the valve 109 to rotate, and the valve stem will also drive the valve disc inside the valve 109 to rotate. When the handle of the adjusting rod assembly 108 is turned to a point where it cannot be turned, the valve 10 9 is fully opened, and the fluid repair material in the heating cylinder 102 will enter the inside of the discharge pipe 110 through the opened valve 109, and then be guided to the inside of the guide bar 113, and then to the inside of the limiting ring 105. When the fluid material enters the inside of the limiting ring 105, the pavement crack repairing device continues to move. The fluid material entering the limiting ring 105 will enter the inside of the crack at the position inside the limiting ring 105. At the same time, the moving limiting ring 105 will scrape off the excess fluid material in the crack. When the limiting ring 105 keeps moving on the pavement crack and fluid material enters the inside of the limiting ring 105, all the pavement cracks passed by the limiting ring 105 can be repaired. During the cleaning stage, when there are still a few cracks on the road surface that need to be repaired by the road crack repair device, the handle of the regulating rod assembly 108 is reset and rotated back to its original position. The regulating rod assembly 108 used at this time will close the valve 109. When the guide bar 113 needs to be cleaned, the controller 115 is used to change the output direction of the motor 122 to reverse its output end. At this time, the corresponding stirring plate 120 will also reverse inside the heating cylinder 102. At the same time, the other single-head screw 119 will also drive the one-way The other end of the clutch 202 is reversed, and the reversed one-way clutch 202 drives one end of the one-way clutch 202 to rotate (due to the characteristics of the one-way clutch 202). When one end of the one-way clutch 202 rotates, the connecting member 204 connected thereto also rotates. At this time, the rotating connecting member 204 drives the winding wheel 205 to rotate with the cooperation of the fixed plate 206. Subsequently, the rotating winding wheel 205 continuously reels the connecting rope 215. When the connecting rope 215 is continuously reeled in, the connecting rope 215, the auxiliary block 208, and the reinforcing bar 207 are connected. With the cooperation of the single hole block 213, the moving rod 209 will continuously move in the direction of the guide bar 113, and the moving moving rod 209 will also drive the moving block 212 to move. At the same time, the moving auxiliary block 208 will also compress the spring 210 with the cooperation of the single hole block 213. When the moving block 212 moves inside the guide bar 113, the moving moving block 212 will scrape off the fluid repair material remaining on the guide bar 113 and guide it to the inside of the limit ring 105. At this time, the remaining small amount of cracks can be repaired with the fluid material scraped from the guide bar 113. When the auxiliary block 208 moves to a point where it cannot move, the controller 115 will again make the output end of the motor 122 rotate forward. At this time, with the cooperation of the rebound force of the spring 210, the single-hole block 213, the reinforcing strip 207 and the auxiliary block 208, the moving rod 209 will drive the moving block 212 to return to its original position. At the same time, the connecting rope 215 will also be unwound from the winding wheel 205. At the same time, the rotation direction of one end of the one-way clutch 202 is the same as the rotation direction of one of the sprockets 203. When the moving block 212 returns to its original position, the pavement crack repair device is moved again to perform the next pavement crack repair operation.
