A spraying method of an environmentally friendly waterproof coating spraying device, using the environmentally friendly waterproof coating spraying device of claim 8, characterized in that: The following steps are involved: Step 1: The paint is introduced into the liquid storage barrel (2) through the feed pipe (3), and at the same time, the servo motor (8) operates to drive the stirring rod (9) to rotate, the rotation of the stirring rod (9) drives the hollow rod (10) to rotate, and the rotation of the hollow rod (10) drives the driving rod (11) to rotate; Step 2: The driving rod (11) rotates to contact the inclined surface of the stabilizing block (13) and squeeze the stabilizing block (13), and the driving rod (11) moves upward due to the reaction force of squeezing the stabilizing block (13). The upward movement of the driving rod (11) drives the hollow rod (10) to move upward, and the upward movement of the hollow rod (10) drives the arc panel (14) to move upward; Step 3: After the driving rod (11) continues to rotate and is out of contact with the stabilizing block (13), the hollow rod (10) moves downward and resets under the elastic force of the reset spring (12), and the downward movement of the hollow rod (10) drives the arc panel (14) to move downward and reset, and the arc panel (14) reciprocates to turn over the paint inside the liquid storage barrel (2); Step 4: When spraying is required, the high-pressure pump (5) is started to pump the paint in the liquid storage barrel (2) into the hose (6), and the paint entering the hose (6) is sprayed out through the high-pressure nozzle (7).
