[0002] The existing pesticide spraying unmanned device is usually carried by a multi-rotor aircraft, has the ability of high-speed flight and long endurance, and can complete the spraying task of a large area of farmland in a short time, however, these unmanned devices still have limitations in the spraying range and cannot completely cover all target areas, in addition, since the independent spray head cannot be controlled independently, the unmanned aerial vehicle cannot achieve accurate control during spraying, resulting in over-spraying in some areas and insufficient spraying in some areas.

[0003] The existing spraying system usually uses unified flow control and cannot perform differential spraying according to the specific topography of farmland, crop distribution and pest control, and at the same time, since there is a lack of precise spray head control technology, the unmanned aerial vehicle cannot accurately divide and adjust the spraying area during spraying.

[0004] Therefore, in view of the above-mentioned problems of the existing pesticide spraying unmanned device, since the spraying range is small and the independent spray head cannot be controlled independently, the unmanned aerial vehicle has low efficiency and cannot accurately control the spraying area during pesticide spraying, an agricultural spraying and mixing device for agricultural planting can be designed. UTILITY MODEL CONTENTS

[0005] In order to overcome the problem that the existing pesticide spraying unmanned device has a small spraying range and cannot control the independent spray head independently, resulting in low efficiency and inability to accurately control the spraying area during pesticide spraying by the unmanned aerial vehicle.
