The exterior wall coating spraying equipment for the building site of claim 1, wherein the top side and the bottom side of the traveling wheel are respectively provided with a fixing lug, the two fixing lugs are fixedly installed on the installation frame, the same wheel shaft is fixedly installed on the two fixing lugs, the traveling wheel is movably sleeved on the wheel shaft, and a plurality of anti-skidding threads are formed in the traveling wheel.

10. A method for painting exterior wall paint for construction sites by using the exterior wall paint spraying apparatus for construction sites according to any one of claims 1 to 9, comprising the steps of:

s1: when the spray gun is used, the spray gun is inserted into the mounting sleeve, and the fastening bolt is screwed for fixing, so that the mounting frame can be mounted on the spray gun;

s2: when spraying is carried out, the pressing plate is pressed to rotate, the push-pull plate is extruded through the two arc-shaped blocks, the push-pull plate is forced to move to drive the four fixing rods to move, the four fixing rods drive the four pulling rods to move, the four pulling rods drive the other four fixing rods to move, the four supporting frames are rotated, and the four ventilation blocks and the four shields are rotated and opened through the rotation of the four supporting frames;

s3: continuously pressing the pressing plate to spray the exterior wall coating, simultaneously starting the air pump to blow air by the air pump, spraying the air through the main air pipe, the branch pipe and the air outlet hole, drying the coating sprayed on the wall, blowing the wall surface which is not sprayed, blowing off attached dust, and ensuring the adhesive force of the coating;

s4: when spraying is carried out, the mounting frame is aligned to a wall surface, the two travelling wheels are in contact with the wall surface, the spray gun is further moved, the spray gun can transversely move to stably spray, and whether the spray gun is in a horizontal position or not is observed through the arrangement of the level ruler;

s5: simultaneously for convenience the spray gun uses, can according to the clamp plate rotate to final position before, at first rotate the joint frame makes the joint frame drives the pivot rotates, and makes the torsional spring atress according to the clamp plate rotates to final position, loosens the joint frame, can be under the torsional spring effort, make the joint frame resets and blocks according to the clamp plate.
