Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt concrete production, and more specifically, particularly relates to an improved asphalt concrete production device. Background Art

[0002] Asphalt concrete pavement has good driving comfort and excellent performance, fast construction speed and low maintenance cost. Most roads use asphalt pavement.

[0003] Based on the above, the inventors found the following problems: In the current production process of asphalt concrete, after the materials are initially mixed, dried and heated, they must be screened, stored, weighed and measured. At present, the screening step is mainly achieved by pouring the mixed aggregate onto the screen, and the large particles will remain on the screen, while the small particles will fall off, thereby achieving the purpose of screening and separation. When a pile of materials is directly poured onto the screening net, the screening net will be blocked, resulting in problems such as incomplete separation and low separation efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an improved asphalt concrete production device is provided, in order to achieve a more practical purpose. Utility Model Content
