Asphalt paving device with air pressure adjusting mechanism for building construction

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of asphalt paving equipment, in particular to an asphalt paving device for building construction with an air pressure regulating mechanism. Background technique [0002] In asphalt paving construction, asphalt raw materials are generally added to the storage tank of the paving device, and the asphalt raw material is discharged from the storage tank to the construction area by the paving device for paving processing. The tank will not solidify due to the temperature drop. Generally, heating equipment is installed inside the storage tank to insulate the asphalt. During the heating and heat preservation process, the storage tank is closed. In the process, due to the discharge of asphalt raw materials, the asphalt raw materials inside the storage tank will be reduced, resulting in an increase in the space above the asphalt raw materials, which will reduce the air pressure above the interior of the storage tank. ...

Problems solved by technology

[0002] During asphalt paving construction, asphalt raw materials are generally added to the storage tank of the paving device, and the asphalt raw materials are discharged from the storage tank to the construction area by the paving device for paving processing. The tank will not solidify due to the temperature drop. Generally, heating equipment is installed inside the storage tank to insulate the asphalt. During the heating and heat preservation process, the storage tank is closed. In the process, due to the discharge of asphalt raw materials, the asphalt raw materials inside the storage tank will be reduced, resulting in an increase in the space above the asphalt raw materials, which will reduce the air pressure above the interior of the storage tank. Due to the external pressure, and the storage tank is closed Yes, only the discharge port is opened, which will make it difficult to unload the material storage tank, affect the speed of unloading, cause the uneven distribution of asphalt in the construction area, and affect the construction efficiency. Therefore, we propose a method with air pressure Asphalt paving device for building construction with adjustment mechanism
