The vehicle is equipped with a dedicated carbon steel tank with a total capacity of 12.05 cubic meters and an effective volume of 11.47 cubic meters. The tank size is 4800 × 2350 × 1550mm, and the tank partition thickness is 3mm, the tank thickness is 4mm, and the head thickness is 5mm. The structure is sturdy and durable, and can load media such as clean water, nutrient solution, pesticides, etc., reducing the shaking of media during driving and meeting the needs of large-scale green spraying operations. It does not require frequent water replenishment, greatly improving work efficiency, and is suitable for maintenance in large green areas. It is equipped with multi-mode and multi form spraying: standard front flushing, rear spraying, and side spraying devices, equipped with a rear work platform and green spraying high-pressure gun. The high-pressure gun can be adjusted 360 ° and can switch between various spraying forms such as direct flushing, heavy rain, moderate rain, and drizzle. The maximum range can reach 30 meters, and the ≥ 16 meters, which can achieve large-scale greening irrigation and precise seedling maintenance; Optional front electric sprinkler and waist flushing device can be installed, which can be operated electrically in the cab to save labor costs. It can efficiently complete special maintenance operations such as watering, fertilizing, and spraying seedlings in urban green belts, parks, and large industrial parks. By flexibly adjusting the spray flow rate and range, it can adapt to the needs of different varieties and heights of vegetation, avoid resource waste caused by excessive spraying, and balance maintenance effectiveness and economy; The tank can be optionally equipped with anti-corrosion treatment to adapt to corrosive media such as pesticides and nutrient solutions, improving equipment adaptability
