Emulsified asphalt spraying device for asphalt road base

The invention belongs to the technical field of road construction, and particularly relates to an emulsified asphalt spraying device for an asphalt road base; the device comprises a connecting base plate, connecting base frames are fixedly mounted at the left and right ends of the rear side of the connecting base plate, and guide wheels are rotatably mounted at the left and right ends of the front side of the connecting base plate; a plurality of mounting holes are formed in the surfaces of the sides, away from the connecting base plate, of the two connecting base frames. A jet head is positioned above a liquid spray head and is parallel to the liquid spray head, so that a conical airflow curtain flow formed by the jet head can wrap an emulsified asphalt curtain flow formed by the liquid spray head; therefore, in the moving and spraying process of the roadbed surface, the conical airflow curtain flow formed by the jet head can blow away dust and other sundries on the roadbed surface in advance, and the proble
