Filling and sealing device for road engineering

The utility model relates to the technical field of road engineering, in particular to a filling and sealing device for road engineering, which comprises a cart plate, a collecting box is fixedly connected to the top of the front end of the cart plate, an exhaust fan is fixedly connected to the top of the collecting box, an exhaust pipe is fixedly connected to one side of the exhaust fan, and a handheld rod is fixedly connected to the other end of the exhaust pipe. The top end of the handheld rod is fixedly connected with an air draft head, and heat dissipation holes are formed in the surface of the air draft fan. Due to the arrangement of the collecting box, the cart plate, the handrail, the anti-skid wheels, the handheld rod, the exhaust fan and the air suction head, when the device is used, a worker pushes the cart plate through the handrail and then holds the handheld rod to align the air suction head to a crack, and the exhaust fan is started to suck garbage and dust in the crack into the collecting box
