[0029] like Figure 1-4 As shown, the other end of the second rotating rod 62 passes through the second connecting plate 61 and is fixedly connected to the first pulley 65, and one end of the first rotating rod 52 passes through the first connecting plate 51 and is fixedly connected to the second pulley 55.

When the first rotating rod 52 rotates to make the cutting block 54 cut the dirt, if it contacts the inner wall of the crack, because its cutting end is set in an arc shape, the cutting block 54 is squeezed into the slide groove 531, which plays a certain protective role on the cutting end of the cutting block 54. Then the spring 56 rebounds to restore the cutting block 54 to its original position, and the next time it rotates into the crack to cut again.
[0036] The motor 64, the electric push rod 13, the vacuum cleaner 7 and the supercharger 15 are all electrically connected to the battery 16 disposed on the frame 1, and are also electrically connected to a control unit (not shown in the figure).
[0037] The working principle of a crack repair device for road and bridge maintenance in this embodiment is as follows: when in use, the vertical height of the mounting frame 4 is adjusted by telescoping the electric push rod 13, so that the cutting block 54 and the cleaning brush 63 enter the crack, the motor 64 is started, the cutting block 54 cuts the harder dirt inside the crack, and then the cleaning brush 63 can clean the harder dirt in the crack, and the vacuum cleaner 7 collects the swept dirt; then the raw material is filled into the crack, and the crack texture and curve can be roughly observed by observing the indicator block 104, so as to cooperate with the moving frame 1 and toggle the operating lever 103 to rotate the rotating plate 102 on the connecting frame 101, so as to change the position of the discharge port of the discharge pipe 9, adjust the feeding position of the raw material, and improve the accuracy of feeding. When cleaning the crack, the staff can also hold the handle on the front side of the frame 1, pull the frame 1 while retreating, and can observe the depth of the crack more intuitively, so as to adjust the height of the mounting frame 4 at any time.
