The invention discloses a cyclic-spraying spray truck for green belt construction. The cyclic-spraying spray truck structural comprises a liquid storage tank, a transport frame, moving wheels, a spraying controller and an anti-skid handle; the spray truck is combined with a liquid delivery pipe through a cyclic sprayer, which is beneficial to cyclic swing of the cyclic sprayer when liquid enters the liquid delivery pipe through a water pump and is driven by magnetic force, the upper surface of green belt plant leaves, the back of the leaves and plant necks can be sprayed comprehensively, the situation that traditional spraying does not hit the target, and the anti-insect effect is improved; meanwhile, spraying force of the liquid can be adjusted, so that collapse of seedlings by high pressure impact is avoided, and the survival rate in planting of the green belt plants is increased.
