Joint filling device for repairing irregular pavement cracks for municipal engineering

The invention discloses a joint filling device for repairing irregular pavement cracks for municipal engineering. The joint filling device comprises a filling pipe, a handle, a spray head and a pressing roller, the handle is installed at the top end of the filling pipe, the pressing roller and an auxiliary wheel are arranged on the left side and the right side of the spray head correspondingly, and the pressing roller is rotationally installed at the bottom end of a transverse frame through a transverse shaft; and the top end of the transverse frame is installed on a water conveying box, a water hole is formed in the lower end face of the transverse frame, the bottom end of a first cavity communicates with a second cavity, the second cavity is formed in the transverse shaft, and the second cavity communicates with the hollow structure in the pressing roller. According to the joint filling device for repairing the irregular road surface cracks for municipal engineering, through the structural design of the auxiliary wheels and the pressing rollers, the purpose of more labor saving can be achieved, meanwhile, the flowing and impact effects of water flow are utilized, rapid cooling of filler and real-time efficient cleaning of the road surface cracks can be achieved at the same time, and meanwhile, bonding of the filler and the fracture surface of the crack is not affected, and the pavement repairing efficiency is greatly improved.
