The present invention relates to a duster installed in an agricultural drone that generates and uses a strong wind, and a case 100, a propeller 110 installed on the inner upper portion of the case 100, and the propeller 110 in the lower part The motor 120 is installed, and the injection unit 140 is installed to be spaced apart from the lower portion of the motor 120 by a predetermined interval.

The installation part of the drone is not limited to one place, and according to the taste of the user, the drone used in the air is installed under the motor, the drone motor arm, and the landing skid is used.

In the case of drones used on the ground, even if the basic frame of an object such as a gyroscope is tilted, the gimbal system, a device that maintains it in an upright state, can be implemented to control the spray angle.

The case 100 is formed in a cylindrical shape penetrating up and down, and is installed in the drone.

An electronic transmission box 150 and a motor controller are installed on the outer periphery of the case, and the controller controls the motor to enable on-off control.

The control unit generates a strong wind by adjusting the speed of the propeller with the electronic transmission box. Therefore, the pesticide can be sprayed farther away.

The motor is fixedly installed inside the case by the upper fixing member 131 , and the injection unit is fixedly installed inside the case by the lower fixing member 132 .

The upper fixing member is composed of a cross-shaped upper support and an upper fixing support protruding upward from the four ends of the upper support, and is fixed to the inner wall of the case with a bolt to the upper fixing member.

The lower fixing member consists of a disk-shaped lower support, a horizontal support of a Korean-line shape penetrating the lower support, and a lower fixing support protruding upward from both ends of the horizontal support, and a bolt on the lower fixing support. It is fixed to the inner wall of the case.

On the other hand, the present invention is a spreader through the electronic motor transmission (Electronic Speed Controller / ESC) of the spreader through the (Pulse Width Modulation / PWM) PWM signal value of the drone flight control controller (Drone Flight Controller / FC) installed directly on the drone control the motor speed.

Alternatively, you can adjust the motor speed of the spreader directly from the controller by inserting the Electronic Speed Controller / ESC ESC of the spreader into the channel that supports the PWM signal value (Pulse Width Modulation / PWM) of the controller's control channel.

The drone flight control controller (Drone Flight Controller / FC) has a communication module installed, and is composed of a storage unit for storing data, a comparison unit, a control unit, a transmission unit, and a reception unit.

That is, in the present invention, a vibration sensor is installed in a drone used in the air, the vibration sensor transmits a signal to the control unit, and when the drone shakes more than a set frequency by the strength of the wind, the control unit determines this, and the electronic motor transmission It sends a signal to (Electronic Speed Controller / ESC) to control the motor speed of the spreader to reduce spraying of pesticides, or stop the motor to prevent spraying.

Alternatively, the control unit of the drone flight control controller (Drone Flight Controller / FC) sends a signal to the PWM controller (Pulse Width Modulation / PWM) of the remote controller used by the user through the transmitter, and operates the alarm means in the PWM controller of the remote controller to make a warning sound make it ring

After confirming the warning sound of the remote controller, the user visually checks the shaking of the drone. A communication module is installed in the PWM controller (Pulse Width Modulation / PWM) of the regulator, and consists of a storage unit for storing data, a comparison unit, a control unit, a transmission unit, and a receiving unit.

When the electronic motor transmission (Electronic Speed Controller / ESC) button installed in the remote controller, which is the input means, is pressed, the signal of the electronic motor transmission (Electronic Speed Controller / ESC) is transmitted through the transmitter of the PWM controller of the remote controller. / FC) through the receiver, and the control unit of the drone flight controller (FC) sends a signal to the electronic motor transmission (Electronic Speed Controller / ESC) to adjust the motor speed of the spreader, Reduce this spraying or stop the motor to prevent spraying.

In addition, the pump (PUMP) that injects pesticides into the spreader and the spreader motor are controlled by separate (Pulse Width Modulation / PWM) PWM signals.

The pump (PUMP) that injects the pesticide into the spreader and the electronic motor transmission (Electronic Speed Controller / ESC) of the spreader together (Pulse Width Modulation / PWM) PWM signal value to the drone flight control controller (Drone Flight Controller / FC) FC In case of connection, it is possible to control signals such as strong injection when moving at high speed, weak injection when moving at low speed, and stopping of injection when stopped through PWM control according to the movement and operation speed of the drone (Pulse Width Modulation / PWM).

Therefore, the present invention can be installed and used on a drone operated on the ground or in the air, and the operation method is also simple, so that the user can use it easily.
