[0002] The folding spray boom arm of the prior art is controlled by two oil cylinders through connecting rods, steel ropes, rope pulleys, etc. to fold and unfold the six-section spray booms on both sides. Due to structural and spatial reasons, the radius of the connecting rod and the rope pulley is relatively small. When the six-section spray booms on both sides are folded and unfolded, the time difference is large. The spray boom on one side has been folded or unfolded, while the spray boom on the other side has just started to move. From the principle of levers, it can be seen that the sprayer frame is twisted due to the uneven weight of the spray boom. In addition, due to the relatively harsh working environment of the sprayer, the connecting rod, steel rope, rope pulley and other structures are easily corroded, resulting in poor stability and short service life of the sprayer.

[0005] 2. The foldable spray rod device of the existing concrete liquid interface agent sprayer is affected by the impact of pressure when the spray rod is working, and the connection is prone to vibration, which makes the spray rod connection unstable and affects the spraying effect.
