The vehicle is equipped with a dedicated Q235 carbon steel tank with a total capacity of 11.61 cubic meters and an effective volume of 11.05 cubic meters. The tank has an external dimension of 4800 × 2300 × 1520mm, with a thickness of 4mm for the tank, 3mm for the partition, and 5mm for the head. It is made using one-time molding technology and large-scale automatic welding equipment. A partition is installed every 1.5 meters inside the tank to reduce medium shaking during operation and ensure operational stability. It can load clear water, nutrient solution, pesticides and other media to meet the needs of large-scale greening spraying operations, without frequent water replenishment, greatly improving operation efficiency. It is suitable for urban greening, large parks and other large-scale operation scenarios. It is equipped with front flushing, rear spraying, side spraying devices and a rear work platform as standard. The platform is equipped with a green sprinkler high-altitude gun, which can rotate 360 ° and flexibly adjust various spraying forms such as direct flushing, heavy rain, moderate rain, drizzle, fog, etc. The sprinkler width is ≥ 14 meters, the range of the high-altitude gun is ≥ 28 meters, and the vertical suction stroke is ≥ 7 meters. It can not only achieve large-scale greening irrigation, but also complete precise seedling maintenance. According to the job requirements, pre installed fully automatic sprinkler guns, medicine trays, medicine pumps, high-pressure spraying equipment, etc. can be selected to expand the spraying function and adapt to different job scenarios. It can efficiently complete special operations such as watering, fertilizing, spraying, lawn maintenance, etc. for urban streets, parks, squares, and large park seedlings. By flexibly adjusting the spraying flow rate and range, it can adapt to the needs of different varieties and heights of vegetation. The tank body adopts a baking paint process, with multiple layers of primer and topcoat spraying. It can be optionally equipped with anti-corrosion and anti rust treatment inside the tank, adapted to corrosive media such as pesticides, to avoid resource waste caused by excessive spraying, and to balance maintenance effect and equipment service life
