The wireless aircraft 40 is typically provided with an electronic control system (not shown) related to flight.

3 is a front view showing the drug spraying device shown in FIG.

2 and 3, the drug spreading apparatus 100 according to the present invention includes a medicine container 120, a dust collecting container 130, a wrinkles 140, and a nozzle bar 150.

The medicine container 120 is disposed on the side of the unmanned aerial vehicle 40, it is preferable that the same capacity of the cylinder is mounted on the left and right sides of the aircraft 40 for the horizontal of the aircraft 40, respectively.

The medicine container 120 is open at the top, and is provided with a stopper 121 for opening and closing the opening, and the opening is attached with a first filter (not shown) that primarily filters the injected medicine.

And a discharge valve 123 for selectively discharging the drug in the medicine container 120 is formed on the lower surface of the medicine container 120. At this time, the discharge valve 123 is opened and closed by the operation button corresponding to the drug spraying function in the wireless controller. Preferably, a second filter (not shown) for secondaryly filtering the medicine in the medicine container 120 is attached to the contact portion (the discharge port of the medicine container) between the discharge valve 123 and the medicine container 120.

The medicine container 120 formed as described above is fixed to both ends of the horizontal frame 110 mounted on the lower surface of the unmanned aerial vehicle 40. Preferably, both ends of the frame 110 is further provided with an auxiliary frame 111 for fixing the respective medicine containers 120, the medicine container 120 is firmly mounted on the auxiliary frame 111.

The dust collecting container 130 is mounted to the lower portion of the center of the frame 110 by a sieve fixed to the frame 110. The dust collecting container 130 is a place where the drug supply pipe 124 connected from the medicine container 120 on the left and right sides of the aircraft 40 is connected, the drug discharged from each medicine container 120 to the dust collecting container 130 After collecting, it is combined in the dust collecting tube 130 to descend to the lower side.

That is, one end of the supply pipe 124 is connected to the discharge valve 123, the other end is connected to the dust collecting container (130). At this time, the dust collecting container 130 is preferably located at a lower position than the discharge valve 123 of the medicine container 120 so that the drug is smoothly discharged by its own weight.

And the lower part of the dust collecting container 130 is connected to the corrugated pipe 140 is in communication with the dust collecting container 130, the nozzle bar 150 is connected to the lower portion of the corrugated pipe 140.

Corrugated pipe 140 is intended to have a flexible role while being easily bent when the nozzle bar 150 is rotated while performing the role of the passage in which the medicine in the dust collecting container 130 is moved to the nozzle bar 150 side. At this time, the lower portion of the corrugated pipe 140 has a fixed-quantity supply valve 170 is built.

The fixed-quantity supply valve 170 is mounted in the corrugated pipe 140, and is a valve that substantially adjusts the amount of the chemical sprayed from the aircraft 40, and is designed to respond to the speed of the unmanned aerial vehicle 40. That is, the fixed quantity supply valve 170 is not provided with a separate operation switch, but is fluidly changed according to the ground speed V checked in the electronic control system provided in the unmanned aerial vehicle 40.

In more detail about the operation principle of the metered supply valve 170, the drug sprayed from the nozzle bar 150 is sprayed the same drug in the same area when the speed of the unmanned aerial vehicle 40 is constant. However, if the speed of the unmanned aerial vehicle 40 is changed, since the moving distance with respect to the ground is different, the drug sprayed on the ground moved at a different speed is not sprayed in the same amount. Therefore, even when the speed of the unmanned aerial vehicle 40 is slow or fast moving, it is preferable to configure the fixed-quantity supply valve 170 in a speed-sensitive manner in order to spray the same amount of the drug compared to the ground according to the speed.

When the unmanned aerial vehicle 40 is stopped, the fixed quantity supply valve 170 is closed, and when the fixed quantity supply valve 170 is slowly moved, the fixed quantity supply valve 170 is gradually opened to be supplied little by little, and the unmanned aerial vehicle 40 When the speed of) increases, the metered supply valve 170 is opened more.

4 is a cross-sectional view taken along the line A-A of Figure 3 showing in detail the metered supply valve of the present invention.

Referring to FIG. 4, the configuration of the fixed-quantity supply valve 170 includes a small first sub motor 171 connected to an electronic control system and operated in a speed-sensitive manner, and a first reducer mounted on the first sub motor 171. 172, a first limit device (not shown) built in the first reducer 172, a rotating shaft 173 coupled to the first reducer 172 and extending into the corrugated pipe 140, and a rotating shaft 173. It is composed of a valve body 174 that is coupled to the inside and rotates in the corrugated pipe 140. Here, the valve body 174 has a spherical shape, and a conventional spherical valve body in which a passage flows in the up and down direction and the medicine flows is used.

On the other hand, the lower portion of the metering supply valve 170 is attached with a third filter (not shown) for finally filtering the sprayed medicine.

The nozzle bar 150 connected to the lower end of the corrugated pipe 140 has a plurality of injection nozzles 152 formed in a fork shape, and the main nozzle 151 which opens in both directions at the lower end of the corrugated pipe 140 and the main nozzle 151. A plurality of injection nozzles 152 are formed integrally in communication with both ends and the middle of the). At this time, the main nozzle 151 is preferably formed to be inclined downward to smooth the flow of the drug.

The drug spreading device 100 formed as described above may further require a pressure pump 160 to smoothly spray the drug.

Pressurized pump 160 serves as a forced conveyance to strongly push the medicine collected in the dust collecting container 130 to the lower corrugated pipe 140, a pump that is often used to move the fluid is used. Such a pressure pump 160 may be used when the height difference from the medicine container 120 to the dust collecting container 130 is low, and is used when the potential energy of the drug is small and does not fall due to its own weight.

In addition, the drug spreading apparatus 100 according to the present invention may further include an angle adjusting means 180 that can rotate the nozzle bar 150.

5 is a perspective view showing a part of the angle adjusting means shown in FIG.

The angle adjusting means 180 is to prevent the drug from flying by the propeller wind power of the unmanned aerial vehicle 40 when spraying the drug while the unmanned aerial vehicle 40 is in flight. In addition, since the nozzle bar 150 is directed downward, there may be a problem that the drug sprayed from the injection nozzle 152 is not uniformly sprayed by the upwind when the unmanned aerial vehicle 40 is moved forward and backward. to be.

Therefore, by turning the nozzle bar 150 in the direction opposite to the flight direction of the unmanned aerial vehicle 40 by the angle adjusting means 180 to be able to suppress the drug from flying by the wind or the wind direction of the propeller as much as possible. do. In addition, it is possible to minimize the damage of the crop due to the downwind of the unmanned aerial vehicle 40 by sufficiently maintaining the height between the unmanned aerial vehicle 40 and the crop.

The angle adjusting means 180 is a second sub-motor 181 mounted on the lower surface of the frame 110, the operation bar (183) is hinged to the nozzle bar 150 while being mounted to the second sub-motor 181. ). In this case, the second sub motor 181 may be rotated by a predetermined angle in a clockwise or counterclockwise direction with a conventional second reducer 182 that reduces the revolutions per minute (rpm) of the second sub motor 181. A second conventional limiting device (not shown) is further included. And the front end of the operation bar 183 mounted on the second reducer 182 and the corresponding second reducer 182 is composed of a gear coupling (185a, 185b) as shown in Figure 5 for 1: 1 power transmission. This would be desirable. In addition, the operation bar 183 is preferably formed to be curved in any one direction in order to avoid interference of the supply pipe 124 when the operation bar 183 is pivoted. More preferably, the front and rear turning angles of the nozzle bar 150 pivoted by the angle adjusting means 180 are set in the range of -80 ° to 80 °.

6 and 7 are side views showing a state of use of the angle adjustment means.

For example, if the operation bar 183 is connected to pass the right side relative to the supply pipe 124 as shown in Figures 6 and 7 operating bar 183 is formed in a substantially ">" shape to the right and clockwise When it is turned to be able to prevent the collision with the supply pipe 124.

Here, the operation of the angle adjusting means 180 is controlled by a speed adjusting stick (not shown) of the radio controller. That is, the radio controller is provided with a stick for moving the aircraft forward or rearward, which can control the aircraft forward and backward as well as control the speed of the aircraft. Therefore, the angle adjusting means 180 is rotated in the opposite direction to the traveling direction of the aircraft at the same time the aircraft is moved by the stick, the angle is adjusted in proportion to the speed of the aircraft by the operation.

The reason why the turning angle of the nozzle bar 150 is adjusted in accordance with the speed is because the strength of the upwind formed in the injection nozzle 152 is different according to the speed of the unmanned aerial vehicle 40. When the speed of the unmanned aerial vehicle 40 is maximized by increasing the angle of the turning angle of the nozzle bar 150 is almost returned to the opposite direction of the flight.

The following briefly describes the use and operation method of the drug spreading apparatus 100 using the unmanned aerial vehicle formed as described above.

8 is a view showing a method of using a drug spreading apparatus using an unmanned aerial vehicle according to the present invention.

Referring to FIG. 8, first, in order to use the spraying device 100 according to the present invention, two medicine containers 120 are filled with the same amount of medicine.

When the medicine is filled, the unmanned aerial vehicle 40 is started and the unmanned aerial vehicle 40 is taken off.

After taking off the unmanned aerial vehicle 40 above the drug spraying area, the drug spraying switch of the radio controller is turned on while moving forward.

With the operation of the drug spray switch, the discharge valve 123 below the medicine container 120 is opened, and the drugs in the medicine container 120 are moved to the dust collecting container 130 by the supply pipe 124.

The drugs gathered in the dust collecting container 130 is forcibly transported to the lower corrugated pipe 140 by the pressure pump 160 while being mixed with each other.

The drug that was forcedly transported through the corrugated pipe 140 is quantitatively moved downward by the fixed quantity supply valve 170 that is sensitive to the speed of the unmanned aerial vehicle 40, and is discharged from each injection nozzle 152 through the main nozzle 151. Is sprayed.

At this time, the spraying of the drug is sprayed while being rotated backward by the speed-sensitive angle adjusting means 180, the drug is sprayed by turning by an angle proportional to the forward speed.

On the other hand, after spraying the drug while moving forward, the unmanned aerial vehicle 40 is rotated to a distant place to move forward again to spray the drug rather than spraying the drug as it is at the end of the spraying stop horizontally, and then spray the drone 40 backwards .

The reason why the unmanned aerial vehicle 40 is sprayed while moving backwards is because there is an intention to save the fuel cost of the unmanned aerial vehicle 40. However, when re-spreading far away, it is difficult to find the exact spraying area and is not large in Korea. In view of the above, a problem may arise in that the returning distance for turning is greater than the moving distance for spreading a short distance.

Accordingly, when the unmanned aerial vehicle 40 is moved horizontally and backward, the speed-sensitive angle adjusting means 180 operates in reverse to pivot the nozzle bar 150 in front of the unmanned aerial vehicle 40, thereby advancing the unmanned aerial vehicle 40. Spray the medicine in the opposite direction.

As described above, the drug spreading apparatus using the unmanned aerial vehicle according to the present invention has been conceived to enable efficient spraying of drugs by a speed-sensitive metering supply valve and an angle adjusting means.

Therefore, it is possible to spray the drug more efficiently when spraying the drug in a large area, or spraying the drug in a narrow area in accordance with the terrain of Korea.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. It will be appreciated.
