The invention provides an intelligent agricultural service system based on a high-resolution satellite. The system comprises an unmanned aerial vehicle, a storage tank, a driving plug, a bearing, a small elastic retaining ring, a large elastic retaining ring, a wind wheel, an inner nut, a driven plug, a sealing ring, a sealing plate and a spring; the storage tank is arranged at a bottom of the unmanned aerial vehicle, and solid fertilizer is arranged in the storage tank; a discharge port is formed in a bottom of the storage tank, a plurality of liquid guide pipes are arranged around the discharge port, and a driving plug is arranged at an outer end of the liquid guide pipe; the wind wheel is arranged on a bearing column at a bottom of the driving plug through a bearing, the driven plug isarranged at an inner end of the liquid guide pipe, and special hydraulic oil is arranged between the driving plug and the driven plug; a cross frame is arranged on the discharge port, a bottom surfaceof the cross frame extends out of a guide column, and the sealing plate is sleeved on the guide column; a limiting plate is arranged at a bottom end of the guide column, and the spring is arranged between the sealing plate and the limiting plate. The higher the flying speed of the unmanned aerial vehicle is, the faster the rotating speed of the wind wheel is, the lifting force of the wind wheel drives the driving plug to move upwards, the driven plug pushes the sealing plate to move downwards, and the larger the fertilizer discharge port is.

    本发明提供一种基于高分卫星的智慧农业服务系统,包括无人机、储料罐、驱动塞、轴承、小号弹性挡环、大号弹性挡环、风轮、内螺母、从动塞、密封圈、封料板、弹簧;储料罐装在无人机底部,储料罐中装有固态肥料;储料罐的底部开设排料口,排料口四周设有多个导液管,导液管外端装有驱动塞;风轮通过轴承装在驱动塞底部的承载柱上,从动塞装在导液管的内端,驱动塞和从动塞之间专有液压油;排料口上设有十字架,十字架底面伸出导向柱,导向柱上套装有封料板;导向柱的底端设有限位板,封料板和限位板之间装有弹簧。无人机的飞行速度越高,风轮的转速越快,风轮的升力带动驱动塞向上移动,从动塞推动封料板下移,肥料排出口越大。
