A sprinkler for a sprinkling vehicle is disclosed and belongs to the field of municipal facilities. The sprinkler for the sprinkling vehicle mainly consists of transverse plates, a motor one, a spraying gun head, a mounting base plate, motors two, support plates, lead screws, a base, a water conveyance pipe, a water inlet, a motor three, a sprinkler head and side bases, wherein the two transverse plates are respectively arranged at both ends of the support plates; the motor one is mounted on the mounting base plate; the spraying gun head is mounted at the shaft end of the motor one; the motors two are mounted on the top of the support plates; the shafts and the lead screws of the motors two are connected by couplings; and the lead screws are matched with the side bases. The motors two drive the lifting and lowering of the side bases so as to drive the up and down movement of the spraying gun head and the sprinkler head, so that water-spraying operation of a spraying gun is combined with water-sprinkling operation of a sprinkling gun, and the sprinkling vehicle equipped with the sprinkler can simultaneously carry out the water-spraying operation and the water-sprinkling operation; in addition, the sprinkler for the sprinkling vehicle enables the spraying gun head to rotate in multi-degree of freedom through the cooperation of the motor one, the motor three and the mounting base plate.
