Abstract: An unmanned aerial vehicle includes a central body having a plurality of sides and a plurality of arms extendable from the central body. Each arm is configured to support one or more propulsion assemblies that provide a propulsion force while the unmanned aerial vehicle is in flight. The arms are configured to transform between a flight configuration in which the arms are extended away from the central body and a compact configuration in which free ends of a first subset of the arms collectively define a rectangular area. Free ends of a second subset of the arms are closer to a yaw-axis of the unmanned aerial vehicle than the free ends of the first subset of the arms. The yaw-axis passes through the rectangular area.

Abstract: An agricultural plant protection machine and a diaphragm pump thereof are provided. The diaphragm pump includes a pump body including a containing cavity; a pump cover on the pump body; a diaphragm in the containing cavity, which and the pump cover surround to form a cavity; and a driving mechanism in the containing cavity. The driving mechanism includes a push rod, a coil assembly and an elastic reset member. The push rod is connected to the diaphragm and the elastic reset member. When the coil assembly is powered on and powered off alternately, the push rod makes a reciprocating linear motion to drive the diaphragm to reciprocate relative to the pump cover so as to reduce or enlarge the cavity.

Abstract: An agricultural unmanned aerial vehicle (UAV) is provided. The UAV includes a central frame, a control circuit, a left arm group, a right arm group and a spraying system. The left and right arm groups each includes a front arm assembly including a second rotor assembly, a rear arm assembly including a third rotor assembly, and a middle arm assembly including a first rotor assembly. In an output direction of downwash flow fields of the left and right arm groups, a height of a rotation plane of the first rotor assembly is lower than heights of rotation planes of the second and third rotor assemblies. The spraying system includes nozzle assemblies. The control circuit is configured to control the left and right arm groups to adjust flight attitude of the UAV. The left and right arm groups output the downwash flow fields in a direction towards the nozzle assemblies.
