[0002] Sprinkler trucks are a type of functional vehicle frequently used in the sanitation industry. Sprinkler trucks are equipped with watering spray devices to achieve purposes such as watering, dust reduction or greening watering.

[0003] At present, some of the irrigation and spraying devices on sprinkler trucks are connected to the nozzles through water hoses. When in use, sanitation workers hold the hoses and nozzles to achieve spraying. This type of structure is generally used for greening irrigation; another part is to directly fix the nozzles on the bottom of the side of the water tank to achieve fixed-position spraying. This type of structure is mostly used for road dust reduction. The irrigation and spraying devices of the above structure are flexible when used in a handheld type, but they consume a lot of manpower; the fixed type saves manpower, but has poor flexibility. In order to meet the actual needs of sprinkler trucks, adjustable irrigation and spraying devices are also being gradually developed.
