The invention discloses an unmanned aerial vehicle with a replaceable functional module and for agricultural plant protection, belonging to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle comprises a vehicle body, connecting rods, a mounting arm, a rotor wing and supporting legs, wherein the mounting arm is hinged to the vehicle body, the connecting rods are rotatably inserted into the mounting arm, swing rods extending downwards are arranged on the connecting rods, hinge rods are hinged to the lower ends of the swing rods, one ends of the hinge rods are hinged to the machine body, and the two connecting rods are driven by a posture adjusting unit to rotate along the hinged positions of the connecting rods and the machine body. The posture adjusting unit drives the two connecting rods to rotate along the hinged positions of the connecting rods and the unmanned aerial vehicle body so as to adjust the posture of the unmanned aerial vehicle; and meanwhile, due to the arrangement of the hinge rods, the hinge rods, the connecting rods and the swing rods form a parallel four-connecting-rod mechanism, and then the rotor wing can be kept in an original state in the posture adjusting process of the unmanned aerial vehicle; and telescopic sleeves are arranged, the supporting legs are inserted into sliding cavities, and the supporting legs are elastically propped through elastic pieces, so the unmanned aerial vehicle can be buffered during landing.

    本发明公开了无人机技术领域的一种可替换功能模块的农业植保无人机,包括机体、连接杆、安装臂、旋翼、支腿,安装臂铰接在机体上,且连接杆可转动地插装在安装臂上,连接杆上设有朝下延伸的摆动杆,摆动杆下端铰接有铰链杆,铰链杆一端铰接在机体上,两个连接杆由姿态调节单元驱动其沿与机体的铰接处转动。通过姿态调节单元驱动两个连接杆沿与机体的铰接处转动,以调节无人机的姿态,同时由于铰链杆的设置,使得铰链杆、连接杆、摆动杆构成了平行四连杆机构,进而使得旋翼在无人机姿态调整过程中能够保持原始状态,通过设置伸缩套,支腿插合在滑动腔内,且通过弹性件对支腿产生弹性抵顶,使得无人机在着陆时,能够具有缓冲。
