Stirring device for construction machinery

The stirring device comprises a stirring processing barrel, connecting bases are fixedly installed on the outer surfaces of the two sides of the stirring processing barrel, rotary connecting rods aremovably installed on the outer surfaces of the connecting bases, and supporting frames are fixedly installed at the ends, away from the connecting bases, of the rotary connecting rods; a processing barrel connecting cover is fixedly mounted on the upper surface of the stirring processing barrel, two movable sealing covers are movably mounted on the upper surface of the processing barrel connectingcover, and a stirring motor is fixedly mounted on the lower surface of the stirring processing barrel. According to the stirring device for the construction machinery, input materials can be cut andsmashed, the situation that due to the fact that the sizes of the materials are different and the materials are caked, stirring and mixing of the materials are not balanced enough is prevented, the stirring processing barrel ca
