The vehicle is equipped with a dedicated tank, with an actual effective volume of up to 20 cubic meters. The tank is made of 5mm thick special volume plates made of Wuhan Iron and Steel, with a sturdy and durable structure and strong corrosion resistance. The internal structure design of the tank is reasonable, which can reduce the shaking of the medium during driving and ensure operational stability. It can load clear water, nutrient solution, pesticides and other media to meet the needs of large-scale greening spraying and farmland irrigation operations, without frequent water replenishment, greatly improving operation efficiency. It is suitable for large-scale greening areas, farmland and other large-scale operation scenarios. Multi mode and multi form spraying: standard front flushing, rear spraying, side spraying devices and rear work platform are installed on the platform, with a greening sprinkler gun installed on the platform. The sprinkler width can reach 16 meters, the water gun lift is 28 meters, and it can flexibly adjust various spraying forms such as direct flushing, heavy rain, moderate rain, drizzle, etc. It can not only achieve large-scale greening irrigation and farmland irrigation, but also complete precise seedling maintenance. With advanced spraying technology, spray is even and delicate, and water resources can be efficiently used. At the same time, it can realize additional operation functions such as fire spraying, expand the operation scene, and carry out special greening and irrigation maintenance: it can efficiently complete special maintenance operations such as watering, fertilizing, and spraying of seedlings in urban green belts, large parks, and parks, and adapt to the needs of vegetation of different varieties and heights by flexibly adjusting the spraying flow and range. At the same time, it can be applied to farmland irrigation, meeting the irrigation needs of large-scale crops, balancing the dual purposes of greening maintenance and agricultural irrigation, avoiding resource waste caused by excessive spraying, and balancing maintenance, irrigation effects, and economy
