The material filling device for bridge expansion joint settlement repairing according to claim 1, wherein two atomizing nozzles are fixedly arranged at the front end of the bottom of the frame, a pressure pump is arranged below the cleaning box, one end of the pressure pump is hermetically fixed with the water tank through a connecting pipe, and the other end of the pressure pump is hermetically fixed with the atomizing nozzles through a connecting pipe.

7. The material filling device for bridge expansion joint settlement repairing according to claim 1, wherein a dust hood is provided at a rear end of the nylon roller and is welded to the frame, a dust collection box is provided above the dust hood, and a negative pressure fan is provided at a rear end of the dust collection box.

8. The apparatus for filling a material for repairing a bridge expansion joint by settlement as claimed in claim 1, wherein a second electric push rod is disposed above the troweling mechanism, an upper end of the second electric push rod is fixedly connected to the frame, a second spring is fixedly disposed between the troweling mechanism and the extension plate, troweling brushes are disposed at lower ends of the troweling mechanism and the extension plate, and auxiliary wheels are rotatably mounted on two sides of the extension plate and are mounted on a plurality of auxiliary wheels.

9. The apparatus for filling a material for repairing a bridge expansion joint by settling as claimed in claim 1, wherein two fans are fixedly installed at the rear end of the bottom of the frame, and two heating wires are installed above the two fans and two sets of heating wires are installed.

10. The use method of the material filling device for bridge expansion joint settlement repairing according to any one of claims 1 to 9, wherein: the method comprises the following steps:

cleaning soil impurities in the expansion joint, starting a fourth motor, enabling a crushing wheel to rotate at a high speed, rapidly scattering convex teeth on the surface of the crushing wheel when the convex teeth are contacted with the soil, discharging the soil along the front of a frame, forming a space to be repaired in a settlement area after the soil impurities in the vertical direction are cleaned, adjusting a first electric push rod according to the depth of the space, enabling nylon rollers to extend into the repairing area, starting the first motor, enabling the two nylon rollers to rotate at a high speed, and cleaning the soil impurities on the inner wall in the rapid rotation process;

step two, treating the generated flying dust, starting a pressure pump, conveying water in a water tank to an atomizing nozzle at the front end of a crushing wheel through a water pipe, spraying the water body downwards in an atomized state, and simultaneously starting a negative pressure fan, so that the flying dust outside a dust hood is sucked into a dust collection box along with air;

repairing the subsidence area, opening a valve of a feed opening, conveying a repairing material to a filling head through a conveying device, starting a third motor, enabling two sector gears to rotate in the same direction and at the same speed, enabling the transmission toothed plate to drive the filling head to move towards one side when the upper sector gear is contacted with the transmission toothed plate in the process of moving the filling head, and enabling the transmission toothed plate to drive the filling head to move towards the other side when the lower sector gear is contacted with the transmission toothed plate, so that the filling head makes reciprocating type front and back displacement at the bottom of the frame;

step four, floating the repairing material, adjusting the depth of the floating mechanism by adjusting a second electric push rod, enabling the extension plate to extend towards two sides in the expansion joint under the reset action of a second spring after reaching the repairing position, enabling the auxiliary wheels at two sides to be attached to the side wall of the expansion joint, driving the floating mechanism to move along with the movement of the frame, and enabling the floating brush at the lower end of the floating mechanism to uniformly spread the repairing material;

and step five, opening the electric heating wire to heat surrounding air, transferring the heat air to the lower part under the action of the fan, and accelerating the evaporation of water when the heat air contacts the repairing material, thereby quickly drying the repairing material.
