This invention relates to the field of agricultural drone technology and discloses a vibration-damping medicine storage box for agricultural drones, comprising a fixed plate, a buffer pad, a shock-absorbing plate, a shock-absorbing spring, a connecting frame, and a medicine box. The fixed plate is bolted to the bottom of the drone, and a buffer pad made of elastic material is installed between the fixed plate and the drone. The shock-absorbing plate is slidably connected to the fixed plate, and the shock-absorbing plate is connected to the fixed plate by a shock-absorbing spring, with both ends of the shock-absorbing spring fixed to the shock-absorbing plate and the fixed plate respectively.
