[0042] The working principle of the present application is as follows:

[0043] Firstly, the operator transports the device to the required area, starts the rotating motor 211 to drive the rotating threaded rod 21 to rotate, and drives the material taking cylinder 22 to move through the connecting structure such as the guide groove plate 282 in the process of rotating the threaded rod 21, until the material taking cylinder 22 falls above the convex part, then starts the knocking lifting rod 27, the knocking lifting rod 27 extrudes the material taking cylinder 22 below the knocking block 25 through the movable plate 26 into the middle of the ground convex part, so that the asphalt road surface is broken, and then the material is further put into the material taking cylinder 22, the knocking lifting rod 27 returns to the original position, and the material taking cylinder 22 is separated from the ground under the action of the pushing force of the pushing spring 222 on the connecting ring 221, so that the material in the material taking cylinder 22 is synchronously separated from the hollow hole formed in the road surface, at this time, the liquid storage tank 41 is used to flow a plurality of gel liquids into the hole through the liquid guide pipe 42, and the next area hole pressing can be carried out;

[0044] When the material in the middle tube of the material taking cylinder 22 accumulates after multiple perforations, the material needs to be unloaded, at this time, the knocking lifting rod 27 is started to move upward, so that the knocking block 25 extrudes the pushing spring 261 to drive the movable plate 26 to move upward, in the process of moving the movable plate 26, the rotating lever 284 is driven to rotate along the sliding rotating lever 281 to move the movable lever 28, in the process of rotating the movable lever 28, the toggle plates 283 at the end of the movable lever 28 move between the buckling sliding plate 29 and the toggle lever 291 in the direction of the material taking cylinder 22, because the movable lever 28 moves, the connecting rod 293 pushes the toggle frame 294 to turn to vertical, and the rotating column 295 on the toggle frame 294 pushes the material taking cylinder 22 to rotate along the rotating connecting rod 231 on the moving block 23, so that the top end of the material taking cylinder 22 faces the material passing column 292 on the sliding plate 29;

[0045] Continue to drive the movable plate 26 to move upward, in the process of self-rotation of the movable lever 28, because the length of the movable lever 28 is fixed, the sliding rotating lever 281 on the movable lever 28 will move close to the movable plate 26 along the moving groove 2821 of the guide groove plate 282, because the material taking cylinder 22 is connected to the rotating threaded rod 21 by the moving block 23 threaded on the rotating threaded rod 21 on both sides of the material passing ring 24, the sliding plate 29 is further driven to move the material passing column 292 into the material taking cylinder 22, and the material in the tube of the material taking cylinder 22 is discharged, at this time, the toggle frame 294 is turned to the vertical state, so that it slides on the outer wall of the material taking cylinder 22 even if it is pushed by the sliding plate 29, and no motion interference is caused, so that the material in the material taking cylinder 22 can be cleaned, after the cleaning is completed, the knocking block 25 is lowered, because the movable plate 26 returns to the original position under the action of the pushing force of the pushing spring 261, the movable lever 28 and the material taking cylinder 22 also return to the original position.

[0046] After the hole pressing is completed, the tamping mechanism 5 on the equipment is moved above the hole, the toggle lever motor 511 is started to rotate the rotating toggle lever 51, the convex wheel 57 is rotated, because the convex directions of the two groups of convex wheels 57 are opposite, when the convex wheel 57 moves to the vicinity of the lifting toggle lever 561, the lifting toggle lever 561 is driven to move upward, the lifting sliding lever 56 slides upward to separate from the rotating ball 522, the spherical buckle bowl 55 below the lifting sliding lever 56 pulls the rolling ball 542 to lift one end of the flattening roller 54, after the convex wheel 57 separates from the lifting toggle lever 561, the flattening roller 54 is pressed downward to hit the ground under the action of gravity, the rotating toggle lever 561 is driven to move left and right to hit the ground, at the same time, because the flattening roller 54 and the lifting sliding lever 56 are connected through the spherical joint connection of the multiple rotating balls 522 and the connecting blocks 521, the spherical buckle bowl 55 and the rolling ball 542, when the flattening roller 54 is inclined, no motion interference occurs;

[0047] In the process of the flattening roller 54 being lifted and hitting the ground, due to the soft soil accumulation under the protruding part of the asphalt road, after the part is removed by the material taking barrel 22, the soil and the hole liquid are quickly mixed to form a muddy slurry, and then the slurry is uniformly flowed into the remaining recessed part under the action of the knocking, so that the protruding part is slowly flattened, the ground flattening can be assisted by the moving device, until the flattening is completed, then the device is moved out of the repair area, and the soil is agglomerated after the liquid is solidified, so that a hard soil layer is formed to replace the original compacted soil layer, then the remaining recessed area is supplemented by asphalt, and the road repair is completed.
