Unmanned aerial vehicle spraying device and unmanned aerial vehicle thereof

Abstract

The invention discloses an unmanned aerial vehicle spraying device and an unmanned aerial vehicle thereof. The unmanned aerial vehicle spraying device comprises an unmanned aerial vehicle body which is provided with a water tank and a water pump arranged in the water tank, driving blocks for winding hinged plates are rotationally arranged on the two sides of the interior of the unmanned aerial vehicle body, and there are multiple hinged plates; the multiple hinged plates are connected through the hinged pieces so that every two adjacent hinged plates can rotate relatively. Water is sprayed through the nozzles on one side of the water box, saplings can be irrigated, on one hand, due to the fact that the water box is close to the positions, needing to be irrigated, of the saplings and is slightly affected by wind power, the irrigation precision can be improved, on the other hand, the water pipe is sleeved with the hinge plates, and the hinge pieces are further arranged between every two adjacent hinge plates, and during use, the unmanned aerial vehicle body is rotated to enable the wind direction to be perpendicular to the rotating plane of the hinge plates, at the moment, the hinge plate cannot be blown to be bent through wind power, and thus the stability of the water box during irrigation is kept.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle technology, in particular to an unmanned aerial vehicle spraying device and an unmanned aerial vehicle. Background technique [0002] Plant protection drones are increasingly used in the fields of pesticide spraying and sprinkler irrigation. The use of sprinkler drones for operations can reduce the labor intensity of operators and improve the efficiency of spraying operations. At the same time, it can avoid direct contact between operators and pesticides, improve safety, and ensure the health of operators. [0003] Chinese invention patent CN112498692A discloses an irrigation sprinkler assembly and a sprinkler drone, belonging to the field of drones. The irrigation sprinkler assembly includes a liquid storage tank, a conveying mechanism and a spraying mechanism. The conveying mechanism includes a number of infusion pipes, and the spraying mechanism includes a number of spray heads. Indepen...

Problems solved by technology

[0004] However, when the device is irrigating some saplings or relatively sparse vegetation, it cannot accurately target the roots of the vegetation or other parts to be irrigated, especially in windy weather, the sprayed liquid will be blown away by the wind. As a result, it leads to deviation from the seedlings to be irrigated, high difficulty in positioning, waste of water when irrigating, and not environmentally friendly
