Controllable water mist spraying device for unmanned aerial vehicle

Abstract

The invention relates to a controllable water mist spraying device for an unmanned aerial vehicle. A top hoisting support comprises a body connecting block, and multiple sets of top supporting rods are fixed to the side wall of the body connecting block by an annular array; a middle rotating driving support comprises multiple auxiliary supporting rods, the top supporting rods and the auxiliary supporting rod are fixedly connected through hoisting arms, and an auxiliary connecting block is fixed between one end of each auxiliary supporting rod and one end of the corresponding auxiliary supporting rod; a rotating driving motor is fixed to the body connecting block; a rotary disc is arranged between the body connecting block and the auxiliary supporting block, and the exterior of the rotary disc is rotatably connected with the outer wall of each sliding bush; a spraying support comprise an annular supporting frame, an impeller motor is fixed to the middle of the supporting frame, drivingimpellers are fixed to the impeller motor, an annular protruding ring is arranged at the bottom end of the supporting frame, and water spraying nozzles are arranged on the side wall of the supportingframe by an annular array. A bottom flow guiding mechanism comprises multiple arc-shaped flow guiding pieces, the tops of the flow guiding pieces are fixed to the outer wall of the supporting frame through spring pieces, and the bottoms of the sliding bushes are connected with the outer walls of the flow guiding pieces through hard pull rods.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle controllable water mist spraying device, which belongs to the field of unmanned aerial vehicle equipment. Background technique [0002] As a main pesticide and water mist spraying mechanism for plant protection drones, in order to realize the spraying of water mist and pesticides, it is common to use ethanol atomizers to use atomized combustion smoke to carry water vapor to spray water curtains. The water curtain spraying effect of the structure is better, but it needs to carry combustion tubes, fuel tanks and other structures, which makes the take-off weight of the UAV larger and affects the flight performance. It is easy to cause the water curtain to scatter, which seriously affects the effect of spraying. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the technical problems of heavy weight of combustion-type water curtain spraying m...
