s3: the contraction part (16) of the concrete pipe (81) is connected with the rotary spray head (14) through a piston ring (17) and a piston pipe (18), a ball (20) and a bearing (19) are arranged in the piston pipe, an inclined outer nozzle (22) is arranged on an end cover (141) on the right side of the rotary spray head (14), concrete flows into a spray cavity (21) of the rotary spray head (14) through the piston pipe (18) and is sprayed out from the outer nozzle (22), and the rotary spray head (14) rotates by means of the centrifugal force of concrete spraying because the spray direction of the outer nozzle (21) is inclined, so that the spray range is expanded;
s4: a return pipe (51) is connected between the conveying cage (5) and the stirring box (3), so that diluted concrete and water in the conveying cage (5) are returned to the stirring box (3) for continuous stirring, and the concrete is prevented from being solidified on a building;
s5: an end cover (141) is connected to the right side of the rotary spray head (14) in a threaded mode, the outer spray nozzle (22) is arranged on the end cover (141), and the purpose of changing the spray range is achieved by changing different end covers (141).
