Filling and sealing machine for highway engineering

The utility model discloses a filling and sealing machine for highway engineering. Including a chassis, trundles are arranged at four corners of the bottom end of the chassis; a handrail is welded atthe upper end of the left side of the chassis; a box body is arranged on the left side of the upper end of the chassis; an air compressor is fixedly mounted at the upper end of the box body through screws; the top end of the air compressor is in butt joint with a storage tank on the inner side of the shell through an air conveying pipe. A speed reducing motor is mounted at the top end of the shellthrough a connecting seat; under the action of the air pump, the road surface and cracks can be effectively cleaned, and the potting effect is improved; during cleaning, water in the water tank is sprayed out through the leakage holes along the water pipe; meanwhile, due to the fact that the containing cavity in the inner side of the shell is matched with the heat preservation layer, the heat preservation effect can be ac
