The vehicle is equipped with a special tank, with a total capacity of 9.99m3 and an effective volume of 9.52m3, which can contain acetone aqueous solution (density of 950 kg/m3). The tank size is 4200 × 2350 × 1550mm. The tank can be equipped with a wave board design, which can reduce the medium shaking during driving, ensure the stability of the operation, meet the needs of large-scale green spraying operations, without frequent water supplement, improve the efficiency of the operation, support the multi scene spraying mode, and can be equipped with front spraying, rear spraying, side spraying and rear spray devices according to the needs to adapt to different operating scenarios; The tail can be equipped with a sprinkler gun, which can adjust various spraying forms such as heavy rain, moderate rain, drizzle, fog, and column. The column spraying range can reach more than 30 meters, which can achieve large-scale greening irrigation and precise seedling maintenance. It can be used for special maintenance operations such as watering, fertilizing, and spraying on urban green belts, park seedlings, and vegetation on both sides of roads. By flexibly adjusting the spraying flow rate and range, it can adapt to the needs of different varieties and heights of vegetation, avoid resource waste caused by excessive spraying, balance maintenance effect and economy, and meet the core needs of municipal greening and park maintenance.
