Problems solved by technology

[0003] In the related technology, when the drone's spreading system is spreading the material, it throws out the material particles horizontally, and the material particles fall to the ground by flat throwing. The downward movement of the material particles only depends on gravity, and it is impossible to control the material according to the schedule. directional spreading

Embodiment 2

[0078] Figure 7 The control flow chart of the agricultural plant protection drone provided by the embodiment of the present invention. like Figure 7 As shown, this embodiment provides a sowing control method for agricultural plant protection drones, including:

[0079] S101, controlling the driving device to drive the spinner of the spreading disc to rotate, wherein the angle between the rotation plane of the spinner and the heading axis of the agricultural plant protection UAV is greater than or equal to 0° and less than 90°, and the sowed material is fed through the spreading disc The mouth enters the spinning plate and is thrown out through the spreading mouth of the spreading plate. The spreading mouth faces the bottom or obliquely downward of the agricultural plant protection drone.

[0080] S102, adjusting the driving parameters of the driving device, so as to adjust the inclination angle at which the spread material is thrown downward.

[0081] The control method o...

Embodiment 3

[0091] This embodiment provides a computer-readable storage medium, on which a computer program is stored, and the computer program can be executed by a processor as follows:

[0092] Control the driving device to drive the spinner of the spreading disc to rotate. The angle between the rotation plane of the spinner and the heading axis of the agricultural plant protection drone is an acute angle. The sowing port is thrown out, and the sowing port faces the bottom or obliquely downward of the agricultural plant protection drone;

[0093] Adjust the drive parameters of the drive to adjust the angle of inclination at which the spread material is thrown downwards.

[0094] The method executed by the processor in this embodiment is the control method described in Embodiment 2. For details, reference may be made to the description of Embodiment 2, and details will not be repeated in this embodiment.

[0095] In several embodiments provided by the present invention, the mutual coupl...

Abstract

An agricultural plant protection unmanned aerial vehicle comprises a vehicle body (10) and a sowing device (20), the sowing device (20) is installed on the vehicle body of the agricultural plant protection unmanned aerial vehicle, the sowing device (20) comprises a sowing disc (21), the sowing disc (21) comprises a feeding port (211), a sowing port (212) and a throwing disc (213), and in the installation state, the included angle between the rotation plane of the throwing disc (213) and the course axis of the agricultural plant protection unmanned aerial vehicle is larger than or equal to 0 degree and smaller than 90 degrees; scattering objects enter the throwing disc (213) through the feeding opening (211) and are thrown out through the scattering opening; the sowing opening faces the lower portion or the inclined lower portion of the agricultural plant protection unmanned aerial vehicle. The driving device (30) is connected with the sowing disc (21) and used for driving the throwing disc (213) to rotate, so that centrifugal force is generated to the sown objects in the throwing disc (213), and the sown objects are thrown out of the sowing opening (212) under the action of the centrifugal force. The directional sowing capability of the sowing equipment can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of agricultural equipment design, and in particular to agricultural plant protection drones, spreading control methods and storage media. Background technique [0002] In recent years, agricultural modernization and precision agriculture have been developing continuously, and the development of agricultural machinery has provided great convenience for agricultural modernization. By carrying a spreading system on the UAV to realize the spreading of particles and powder particles, such as rice seeding, fertilization and other scenarios, it provides an efficient and convenient operation method for agricultural modernization. [0003] In related technologies, when the drone's spreading system is spreading materials, it throws out the material particles horizontally, and the material particles fall to the ground by flat throwing. The downward movement of the material particles only depends o...
