The paint liquid flows into the inside of the collection box (21) through the drain tank (17), the guide tank (19), the round hole (20) and the collection hose (22) for centralized collection. S5. During the operation, the multiple movable wheels (7) can be controlled to move autonomously and automatically spray the building spraying area. S6. After the spraying is completed, the liquid pump (5) and the control motor (412) are turned off, and the electric push rod (11) is started to retract, so that the spraying mechanism (4) is retracted. S7. Finally, recycle the paint liquid inside the collection box (21) to complete the recycling.
