The invention discloses an
asphalt paving device with an air pressure adjusting mechanism for
building construction in the technical field of
asphalt paving equipment. The
asphalt paving device comprises a vehicle body and a
material storage tank, a pressing roller is installed on the outer wall of the left side of the vehicle body, a cover plate is fixedly installed on the outer wall of the top of the
material storage tank, and a baffle is hinged to the outer wall of the top of a feeding hopper; an adjusting device is arranged at the top of an inner cavity of the
material storage tank, a heating plate is arranged in the center of the inner cavity of the material
storage tank, mercury in the device expands after being heated, a check block can be pushed leftwards, the check block is inserted into an opening, the opening is sealed, a movable plate becomes a closed plate body, a spring is pushed to expand, and a movable rod drives the movable plate to move downwards. The distance between the asphalt
raw material and the movable plate is reduced, so that the air pressure between the asphalt
raw material and the movable plate is not greatly reduced, normal blanking of asphalt is ensured, and the asphalt
raw material is uniformly scattered in a construction area.
