Concrete trolley for construction site

The invention discloses a concrete trolley for a construction site, and relates to the field of building construction. The concrete trolley comprises a hopper; a power mechanism is installed at the bottom end of the hopper; a fixing sleeve is fixed to the bottom end of the power mechanism; a moving block is connected to the inside of the fixing sleeve; a top block is arranged at one end of the moving block; and a lifting mechanism is installed at the portion, at the top end of the power mechanism, outside the hopper. According to the concrete trolley for the construction site, by arranging a stirring mechanism, the hopper and a rotating wheel, a constructor pushes the trolley through a push rod, the rotating wheel rotates to drive a third rotating rod to rotate, the third rotating rod rotates to drive a third chain to move so as to drive a fourth rotating rod to rotate, and three rotating plates are driven to rotate through the transmission of a fourth chain, so that concrete in different layers is stirred, t
