Document Type and Number:
WIPO Patent Application WO/2022/061771
Kind Code:
A1
Abstract:
An agricultural plant protection unmanned aerial vehicle, comprising a vehicle body (10) and a sowing apparatus (20). The sowing apparatus (20) is installed on the vehicle body of the agricultural plant protection unmanned aerial vehicle. The sowing apparatus (20) comprises: a sowing disk (21), which comprises a feeding port (211), a sowing port (212) and a spinning disk (213), wherein when in an installation state, the included angle between a rotation plane of the spinning disk (213) and the yaw axis of the agricultural plant protection unmanned aerial vehicle is greater than or equal to 0° and less than 90°, sowing materials enter the spinning disk (213) by means of the feeding port (211) and are spun out by means of the sowing port, and the sowing port faces toward the lower portion or an inclined lower portion of the agricultural plant protection unmanned aerial vehicle; and a driving device (30), which is connected to the sowing disk (21) and is used for driving the spinning disk (213) to rotate, such that a centrifugal force is generated for the sowing materials in the spinning disk (213) so as to spin the sowing materials out from the sowing port (212) under the action of the centrifugal force, and the directional sowing capability of the sowing apparatus can thus be improved.
