The invention relates to a street brick laying machine. The street brick laying machine comprises a lifting rod, hanging rods, an outer frame, baffle sheets, springs, a stretching handle, a fixed hanging hook and the like. The lifting rod is used for lifting a brick laying frame; the hanging rods are used for fixing the brick laying outer frame; the outer frame is used for fixing brick laying lattices; the baffle sheets 4 are fixed on the inner side of the outer frame; the baffle sheets 5 are telescopic movable cuboid metal blocks, and are vertical to the baffle sheets 4; the springs are arranged on the two ends of the baffle sheets and are used for restoring the baffle sheets; the brick laying lattices are square lattices which are formed by intersecting the baffle sheets 4 and the baffle sheets 5; contracting handles are used for fastening the steel wires of the baffle sheets; one end of each steel wire is fixed on a reel below the corresponding contracting handle, and the other end is connected with the corresponding baffle sheet; the stretching handle is used for loosening the contracting handles, and is connected with the reels below the contracting handles; and the fixed hanging hook is used for fixing the outer frame of the brick laying lattices. By adopting the street brick laying machine, the work efficiency can be improved; the laying area at one step can reach 4 square meters; and the procedures of manual brick carrying and brick laying are omitted, so that the brick laying machine is convenient, rapid, safe and labor-saving.
