Problems solved by technology
This type of device has the following disadvantages: Since the attitude of the multi-rotor aircraft needs to be constantly changed during flight to offset the influence of the airflow on the heading and position accuracy, and the spray head is directly fixed on the frame of the sprayer, it is impossible to flexibly control the direction of the spray head

Embodiment 1
[0033] In the prior art, the multi-rotor airborne spraying device is composed of a medicine box, an infusion tube, a DC motor, an electromagnetic flow pump, a centrifugal tooth disc, and a one-way valve. When in use, the electromagnetic flow pump is used to absorb the liquid medicine to the DC motor Driven centrifugal chainring. The droplets are atomized by the high-speed rotating centrifugal disc, and then sprayed out through the nozzle after passing through the guide tube. The position of the spray head is fixed with the multi-rotor unmanned pesticide applicator, and the angle will not change with the change of the flight attitude, which will lead to unstable spraying and affect the utilization rate of pesticides.
[0034] The nozzle stabilization device for the multi-rotor unmanned spraying machine described in this embodiment, such as figure 1 and 2 As shown, it includes a nozzle 1, a nozzle bracket 2, a microcontroller, an inertial measurement unit 3, and a rotary drivi...

The invention discloses a sprayer stability augmentation device and method for a multi-rotor-wing unmanned pesticide spraying machine. The sprayer stability augmentation device comprises a sprayer, a sprayer support, a microcontroller, an inertial measurement unit and a sprayer support rotation drive device. The sprayer and the inertial measurement unit are both fixed to the sprayer support. The microcontroller is electrically connected with the inertial measurement unit and further connected with the sprayer support rotation drive device used for driving the sprayer support to rotate. The sprayer support rotation drive device comprises a structure support, a transverse roller steering engine and a pitch axis steering engine. The method comprises the steps that the current transient acceleration and the angular speed of the sprayer are obtained, the current motion posture of the sprayer is obtained after filtering and posture resolving, and then the pointing direction of the sprayer is adjusted according to the posture. According to the sprayer stability augmentation device and method for the multi-rotor-wing unmanned pesticide spraying machine, the direction of the sprayer can be adjusted according to the operation posture, and influence on the pointing direction of the sprayer from the flying postures of a multi-rotor-wing craft can be reduced to the maximum extent, so that the pointing direction of the sprayer is stable.
Description
technical field [0001] The invention relates to the field of research on agricultural unmanned aerial vehicles, in particular to a nozzle stabilization device and method for a multi-rotor unmanned pesticide applicator. Background technique [0002] The multi-rotor light and small unmanned aerial vehicle has the characteristics of small size and rapid attitude response, which is convenient for rapid deployment and use in orchards with complex terrain. In the field of practical agricultural applications, fixed-point and quantitative application of pesticides on crops by drones equipped with spray devices can greatly improve the utilization rate of pesticides. [0003] At present, the more reliable multi-rotor airborne spraying device is composed of a medicine box, an infusion tube, a DC motor, an electromagnetic flow pump, a centrifugal tooth disc, and a one-way valve. Centrifugal chainring. The liquid droplets are atomized and ejected by the high-speed rotating centrifugal ...
