The embodiment of the invention provides an agricultural unmanned aerial vehicle, and relates to the field of unmanned aerial vehicle plant protection. The agricultural unmanned aerial vehicle comprises a vehicle body main frame, a plurality of vehicle arms and a storage box, the length of the vehicle body main frame in the front-back direction is larger than the length of the vehicle body main frame in the left-right direction, one end of each vehicle arm is connected with the corner position of the vehicle body main frame, the other end of each vehicle arm is connected with a power device, and a feeding port of the storage box is formed in the left side and/or the right side of the vehicle body main frame. And the blade is close to the body main frame. A battery is placed in the machine body main frame, the battery is arranged in the middle to ensure that the gravity center of the whole machine is stable, the length of the machine body main frame in the front-back direction is larger than the length of the machine body main frame in the left-right direction, the length of the machine body main frame in the front-back direction can be increased, and the space of the left side and the right side of the machine body is increased. Due to the fact that the feeding port of the storage box is formed in the left side and/or the right side of the machine body main frame, the space of the left side and the right side of the machine body main frame is enlarged, the feeding port is close to the machine body main frame, and the opening area of the feeding port of the storage box can be increased.

本发明的实施例提供了一种农业无人机，涉及无人机植保领域。该农业无人机包括机体主框架、多个机臂以及储存箱，机体主框架在前后方向的长度大于在左右方向的长度，机臂的一端和机体主框架的边角位置连接，机臂的另一端和动力装置连接，储存箱的进料口设置于机体主框架的左侧和/或右侧，且与机体主框架贴近。机体主框架的内部用于放置电池，将电池中置以确保整机重心稳定，机体主框架在前后方向上的长度大于在左右方向上的长度，能拉长机体主框架在前后方向上的长度，使机体左右两侧的空间增大，由于储存箱的进料口设置在机体主框架的左侧和/或右侧，增大机体主框架左右两侧的空间，且进料口和机体主框架贴近，能增大储存箱的进料口的开口面积。
