The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs. Accordingly, the shape of each element shown in the drawings may be exaggerated to emphasize a clearer description.

The terms first, second, etc. may be used to describe various elements, but the elements should not be limited by terms. Terms are used only for the purpose of distinguishing one component from another.

The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the terms "comprises" or "having" and the like are used to specify that there is a feature, a number, a step, an operation, an element, a component or a combination thereof described in the specification, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

1 to 3, the UAV 100 includes a main body 110, an engine 120, a driving unit 130, and a variable operation unit 140. The multi- .

The main body 110 includes a frame 111 forming a frame, a plurality of first extension frames 112 extending forward and backward with a predetermined length about the frame 111, A second extension frame 113 extending from the end of the frame 111 in a direction orthogonal to the first extension frame and a support 114 installed under the frame 111 and supported on the ground when the unmanned airplane takes off and land And a bearing housing 112a is provided in the first extension frame 112. [

The engine 120 is installed in the center of the main body and generates power by burning fuel (gasoline, kerosene, etc.) supplied from a fuel tank (not shown).

The drive means 130 includes a drive pulley 131 connected to the shaft 121 drawn out from the engine 120 and a belt for interconnecting the driven pulley 133 disposed adjacent to the drive pulley 131, And a driven pulley 133 extending in a direction perpendicular to the axis 121 in the first extended frame 112 and supported by the bearing housing 112a, A first drive pulley 135 and a second drive pulley 136 respectively coupled to both ends of the main shaft 134 and a second drive pulley 135 and a second drive pulley 136 connected to both ends of the main shaft 134, A first driven belt 137 connecting the first driving pulley 135 and one driven pulley and a second driven pulley 137 connecting the first driving pulley 135 and one driven pulley, 136 and a second driven belt 138 connecting the other driven pulley.

The first driven belt 137 and the second driven belt 138 are connected to each other by a certain angle of twist in the process of being connected to the driven pulley 139 side. However, since the direction of twisting is different, the rotating direction of the driven pulley is different .

4A, the first driven belt 137 connected to the first driving pulley 135 provided on the main shaft 134 is connected to the point A of the driven pulley 139 located on the left side of the drawing And the driven pulley 139 is rotated counterclockwise even if the rotation of the main shaft 134 rotates in the clockwise direction when the second driven belt 138 is hooked to the point B of the driven pulley 139 ' And the driven pulley 139 'rotates in the clockwise direction and generates lifting and driving force.

Conversely, when installed as shown in FIG. 4B, the driven pulley 139 rotates in the clockwise direction and the driven pulley 139 'rotates in the counterclockwise direction to generate the lift and the driven pulley.

The rotating direction of the rotor blades can be changed in the direction of the center of the main body or in the outward direction by varying the twist directions of the first and second driven pulleys even if the first and second driven pulleys are operated by one engine, It becomes possible.

In addition, since a plurality of rotor blades are simultaneously operated by one engine operation, the rotation of the rotor blades can be uniformly performed as compared with a wireless airplane operated individually by a conventional motor, so that the control of the UAV can be facilitated.

On the other hand, if the first follower belt and the second follower belt are twisted in the same direction, they may rotate in the same direction in the rotating direction of the rotor.

The variable operating portion 140 is connected to a link shaft 141a extended from the motor 141 and includes a servo motor 1141 mounted on the second extended frame side for sliding the variable link according to a control signal, And a rotating blade 144 provided on the variable link 143 and having a variable pitch in accordance with a change in the position of the variable link 143. The variable link 143 includes: .

That is, when the rotary member is rotated by the driving means operated by the engine and receives the rotary force, the variable operation unit 140 slides the variable link on the rotary shaft through the servo motor and adjusts the angle of the rotary blade connected to the variable link So that lift and thrust generated through the rotor can be controlled.

In the present invention, as shown in FIG. 5, the pesticide application unit 150 is further provided.

The pesticide spraying unit 150 includes a storage tank 151 in which pesticides are stored and a plurality of spray nozzles 155 arranged at regular intervals so as to spray the pesticide stored in the storage tank 151 with a predetermined interval And a pump 153 for supplying the pesticide through a discharge pipe 154 connected to the spray nozzle 155.

Here, the pesticide spraying unit 150 operates through an operation button provided in the control means for operating the UAV.

Hereinafter, an operation state of the present invention will be described with reference to the accompanying drawings.

When the engine 120 is operated through the control means, the main shaft 134 connected to the engine is rotated simultaneously with the operation of the engine 120. The main shaft 134 includes the first drive pulley 135 and the second drive pulley 135, 2 drive pulley 136. [0064]

Since the rotating first and second driving pulleys are individually connected to the driven pulley by the first driven belt and the second driven belt, respectively, the respective driven pulleys are individually rotated, and the driven pulleys are connected to the driven pulley The rotor blade rotates.

At this time, since the variable operation portion is connected to the rotating rotor blade, the rotation angle of the rotor blade is adjusted through the operation of the variable operation portion to generate lifting and driving force.

Thus, by connecting the driving means for simultaneously operating a plurality of rotor blades to one engine, it is possible to fly for a long time through the engine, and it is possible to exert a relatively large force compared to the dron operated by the conventional general electric motor, It is possible to carry or mount a heavy object, so that it is possible to easily cope with various conditions (environmental exploration, spraying of pesticide, transportation of goods, and the like).

In addition, since the twist positions of the first driven belt and the second driven belt connected to the rotor blade are different from each other, it is possible to adjust the rotation directions of the rotor blades differently or in the same manner, Can be freely adjusted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. There is no doubt that it is within.
