Material broadcasting device, unmanned aerial vehicle, and material broadcasting method

An unmanned aerial vehicle, comprising:

• an unmanned aerial vehicle body,
• a material box,
• a flight control module, and
• a the material broadcasting device, comprising:
• a material picker, comprising:
• a housing provided with an upper opening and a lower opening, the upper opening being in communication with a material box;
• and
• a material picking wheel located at the lower opening and driven to rotate by a driving member, the material picking wheel being provided with a material picking cavity thereon to accommodate materials;
• a controller electrically connected with the driving member;
• a material feeder;
• and
• a material receiver located below the material picking wheel and in communication with the material feeder, wherein the materials in the material picking cavity enter the material feeder through the material receiver and are broadcast through the material feeder,
• wherein the material picker of the material broadcasting device is connected below the material box, the material feeder of the material broadcasting device is connected with the unmanned aerial vehicle body, and the controller is electrically connected with the flight control module.

A material broadcasting method, implemented by an unmanned aerial vehicle, which comprises:

• an unmanned aerial vehicle body,
• a material box,
• a flight control module, and
• a the material broadcasting device , comprising:
• a material picker, comprising:
• a housing provided with an upper opening and a lower opening, the upper opening being in communication with a material box;
• and
• a material picking wheel located at the lower opening and driven to rotate by a driving member, the material picking wheel being provided with a material picking cavity thereon to accommodate materials;
• a controller electrically connected with the driving member;
• a material feeder;
• and
• a material receiver located below the material picking wheel and in communication with the material feeder, wherein the materials in the material picking cavity enter the material feeder through the material receiver and are broadcast through the material feeder,
• wherein the material picker of the material broadcasting device is connected below the material box, the material feeder of the material broadcasting device is connected with the unmanned aerial vehicle body, and the controller is electrically connected with the flight control module,
• wherein the material broadcasting method comprises:
• determining a target broadcast quantity according to pre-acquired flight status information and preset broadcasting parameters, when the unmanned aerial vehicle broadcasts the materials;
• determining a target rotation speed of the material picking wheel in the material broadcasting device of the unmanned aerial vehicle according to the target broadcast quantity;
• and
• controlling the driving member of the material broadcasting device to drive the material picking wheel to rotate at the target rotation speed, to allow the material broadcasting device to broadcast the materials in the target broadcast quantity.
