The present invention relates to an unmanned aerial vehicle control apparatus, and more particularly, to an unmanned aerial vehicle control tank capable of circulating a drug in a chemical tank through a circulation apparatus.

Generally, pesticide spraying work for improvement of quality and increase of yield by controlling pests of crops is carried out by diluting pesticide with water and spraying it in an atomizer. In recent years, a method of distributing pesticides and environmentally friendly medicines while remote control using an unmanned helicopter has been carried out as a way to perform a spraying operation more conveniently.

1, a spraying operation using the unmanned helicopter 1 of the unmanned aerial vehicle control apparatus is generally performed by using an injection body 3 extending in the transverse direction of the unmanned helicopter 1 by a predetermined length, And a chemical tank 7 for supplying a chemical solution to the spray nozzle 4. The chemical tank 7 is connected to the spray nozzle 4 and the chemical tank 7,

The chemical liquid pressurized from the pump driven by the power source of the battery mounted on the unmanned helicopter 1 is transmitted to the spray nozzle 4 through the spray body 3 and the chemical liquid sprayed from the spray nozzle 4 Is scattered by the crop by the high-speed downward current generated in the main rotor of the unmanned helicopter 1. 2 shows a state in which the medicine tank 7 is separated from the injection body 3 and the connection port 5 of the injection body 3 is opened. The connector 5 is connected to a discharge port (not shown) at the bottom of the chemical tank 7 to receive the medicine stored in the chemical tank 7.

Generally, the controlling agent mainly uses a liquid formulation and an emulsifiable concentrate (milk) or a wettable powder as a water-soluble liquid agent. Among them, the wetting agent is advantageous compared with the emulsion in packaging, transporting and storing because the preparation is solid, but the powder is precipitated on the bottom of the chemical tank 7 over time. The precipitated powder clogs the outlet of the chemical tank (7), which makes it difficult to smoothly spray.

The present invention is intended to solve the problems of the prior art as described above, and the present invention is to prevent a phenomenon that the powder contained in the medicament is smeared and the discharge port is blocked by stirring the medicine stored in the medicine tank.

According to an aspect of the present invention for achieving the above object, the present invention provides a medicine circulation apparatus including a medicine container body installed in a UAV and having a storage space therein, a circulation pump installed in the medicine container body, A suction unit connected to the circulation pump and connected to at least a portion of the storage space to suck the medicine in the storage space; at least a part of the suction unit connected to the storage space, through the suction unit, And discharging the air into the space.

The suction unit is installed on the lower portion of the medicine container body, and the discharge unit is installed on the upper portion of the medicine container body relative to the suction unit.

The suction part and the discharge part are connected to the same surface of the medicine container body and are installed so as to be spaced apart from each other in the up, down, left and right positions.

The discharge portion is provided with a discharge pipe inserted into the storage space, and the discharge hole of the discharge pipe extends toward the center of the storage space.

And a sensor unit installed in the circulation pump or the suction unit to measure the suction amount of the medicine.

According to another aspect of the present invention, there is provided an apparatus for spraying an aerosol spray, comprising: an unmanned airplane; a spray body installed in the unmanned airplane and having at least one or more spray nozzles; And circulation means installed in the container for circulating the medicine stored in the storage space.

The circulation means includes a circulation pump, a suction portion connected to the circulation pump and at least a part of which is connected to the storage space to suck the medicine in the storage space, and a suction portion connected to the circulation pump, And a discharge unit for discharging the medicine circulated by the circulation pump to the storage space after being introduced through the circulation pump.

The following effects can be expected in the unmanned aerial control tank and the unmanned aerial control system using the same according to the present invention as described above.

In this embodiment, the circulation means continuously circulates the medicine stored in the chemical tank, thereby preventing the powder contained in the medicine from sticking to the bottom of the chemical tank. Thus, clogging of the discharge port of the chemical tank is prevented, and the operation reliability of the control apparatus is improved.

In addition, since the medicine is continuously circulated by the circulation means, there is also an advantage that various medicines including a wettable agent, which has not been conventionally used for aviation control, can be applied.

In addition, in the present invention, since the suction unit and the discharge unit of the circulation unit are spaced apart from each other in the up / down / left / right directions, circulation within the storage space can be more effectively performed.

The construction of the unmanned aerial vehicle control apparatus according to the present invention will be described with reference to FIGS. 1 and 2. FIG. The unmanned aerial vehicle control apparatus according to the present invention includes an unmanned airplane 1 and an injection body 3 coupled to the unmanned airplane 1. 1 and 2 show a helicopter-type UAV 1, which is not necessarily limited thereto. The unmanned airplane 1 may be of various types such as a small airplane without a drones or a propeller.

The injection body 3 is coupled to a lower portion of the UAV 1, and a flow passage is formed therein. The flow path forms a path through which the medicament in the medicament container described below is moved, and is connected to the plurality of spray nozzles 4. The injection nozzle 4 is a part where the medicine is finally sprayed, and is opened downward.

The injection hole (5) is opened in the injection body (3). The connector (5) is a portion into which the medicine flows from the medicine container, and a plurality of the injection port (3) may be formed in one injection body (3). In this embodiment, two connection ports (5) are formed in the injection body (3) so as to correspond to the two medicine containers.

A drug container is installed in the UAV 1. As shown in FIG. 3, the medicament container is a kind of container in which a storage space S for storing medicines is formed. The medicine container is made of a lightweight material such as a synthetic resin, and can be fixed to one side of the UAV 1 through a bracket (not shown) or the like.

The structure of the medicament container is described in detail. The medicament container body 10 in which the storage space S is formed forms the skeleton and the appearance of the medicament container body. The medicine container body 10 is not necessarily limited to have a curved outer surface as shown in FIG. 3, but may be various stereoscopic images.

A drug dispensing part 11 is formed on the upper part of the medicine container body 10 and a medicine discharging part 12 is formed on the bottom of the medicine container body 10. The medicine dispensing part 11 is selectively shielded by a separate cover and the medicine dispensing part 12 communicates with the connection port 5 of the injection body 3 to supply the medicine.

A circulation means (20) is provided in the medicine container body (10). The circulation means 20 circulates the medicine stored in the storage space S and continuously discharges the medicine out of the storage space S and then supplies it again into the storage space S, Is stirred.

The circulation means 20 includes a circulation pump 21, a suction unit 25, and a discharge unit 30. The circulation pump 21 provides power for circulating the medicine. In the present embodiment, power is supplied from the main body of the UAV 1 and is transmitted. Although not shown, a connector and a cable for power supply may be provided in the circulation pump 21.

The circulation pump 21 is preferably installed at a lower portion of the medicine container body 10. This is to allow the circulation pump 21 to be located at a position close to the bottom where the powder component contained in the medicine becomes a precipitate. The circulation pump 21 is installed at a position where the sediment is likely to sink, so that more efficient stirring and circulation of the medicine can be achieved. Reference numeral 22 denotes a bracket for fixing the circulation pump 21 to the medicine container body 10.

The suction unit 25 is provided in the circulation pump 21 and both ends of the suction unit 25 are connected to the circulation pump 21 and the medicine container body 10, respectively. The medicine suction end 27 provided at one end of the suction unit 25 sucks the medicine from the medicine container body 10 and the pump suction end 26 provided at the other end transmits the medicine to the circulation pump 21 do. The suction unit 25 can be seen as a kind of pipe.

It is preferable that the suction unit 25 is installed under the medicine container body 10 like the circulation pump 21. In this embodiment, the suction unit 25 is installed to extend in the left-right direction below the medicine container body 10 with reference to FIG. Therefore, the medicine at the bottom of the storage space S can be sucked through the suction unit 25. [ As shown in FIG. 5, the medicine suction end 27 is opened toward the inside of the storage space S.

At least a part of the discharge part 30 connected to the circulation pump 21 is connected to the storage space S and flows into the storage space S through the suction part 25, . The discharge portion 30 can be regarded as a kind of pipe as the suction portion 25.

Both ends of the discharge portion 30 are connected to the circulation pump 21 and the medicine container body 10, respectively. The pump discharge end 31 at both ends of the discharge portion 30 is connected to the circulation pump 21 and the medicine discharge end 33 is connected to the medicine container body 10. Unlike the suction unit 25, the discharge unit 30 extends in the vertical direction of the medicine container body 10 with reference to FIG. Accordingly, the medicine delivered from the circulation pump 21 located at the lower part can be supplied to the upper part.

4, the suction unit 25 and the discharge unit 30 are connected to the same surface of the medicine container body 10, and the upper and lower (Y-axis direction) and left-right (X- As shown in FIG. This is because the suction portion 25 and the discharge portion 30 extend in different directions as described above. As a result, the medicine suction end 27 of the suction unit 25 and the medicine discharge end 33 of the discharge unit 30 are separated from each other in the vertical direction And is spaced at a constant distance L in the left and right direction. As a result, the agent in the storage space S can be agitated and circulated more efficiently.

Meanwhile, as shown in FIG. 6, the discharge unit 30 is provided with a discharge pipe 35. The discharge pipe 35 is a kind of pipe connected from the discharge end 33 of the discharge part 30 and may be regarded as a part of the discharge part 30. The discharge hole 38 of the discharge pipe 35 extends in the center direction (Z-axis direction) of the storage space S. As the discharge hole 38 protrudes toward the center of the storage space S, the medicine discharged through the circulation pump 21 can be supplied to the center portion of the storage space S, not to the edge of the storage space S. Therefore, the circulation of the medicine in the storage space S can be performed more smoothly.

As a result, in the circulation of the drug through the present invention, the portion in which the medicine is sucked and the portion to be discharged are set to be separated from each other by a certain distance in the X axis, Y axis, and Z axis directions, .

Although not shown, the circulation pump 21 or the suction unit 25 may be provided with a sensor unit. The sensor unit measures the suction amount of the medicine through the suction unit 25. The sensor unit intermittently operates the circulation pump 21 when the suction amount is reduced and stops the circulation pump 21 when there is no suction amount . This can prevent the power consumption of the UAV 1 from being wasted.

Hereinafter, the operation of the unmanned aerial vehicle control apparatus according to the present invention will be described.

First, the unmanned airplane 1 takes off while the medicine is stored in the medicine container of the unmanned airplane 1. The unmanned airplane 1 is controlled so as to inject the medicine in the air, and the medicine is injected through the injection nozzle 4. For reference, FIG. 1 shows a state in which the medicine is sprayed through the injection nozzle 4.

The powder component contained in the medicine stored in the storage space S of the medicine container slowly sinks to the bottom of the storage space S after a certain time. If the powdery material is accumulated or adhered to the medicine discharging part 12 of the medicine container, the amount of the medicine to be supplied through the medicine discharging part 12 may be reduced or completely stopped.

Therefore, the circulating means 20 of the present invention operates periodically / non-periodically to agitate the medicament, circulate the medicines, and mix the medicinal components to prevent precipitation of the powder components. The control of the circulation means 20 may be performed by a control unit, which controls the operation of the circulation pump 21 of the circulation means 20.

When power is supplied from the power supply unit of the UAV 1, the circulation pump 21 operates and sucks and discharges the medicine. More precisely, after the medicine in the storage space S is sucked through the suction unit 25 by the suction force of the circulation pump 21, the medicine in the storage space S passes through the circulation pump 21, ). Through this process, the medicament is prevented from being precipitated while being stirred and circulated.

At this time, the medicine suction end 27 of the suction unit 25 and the medicine discharge end 33 of the discharge unit 30 are not only different in height but also spaced in the left and right direction. Thus, inhale and discharge occur at distant locations of the storage space S, which can lead to efficient drug agitation and circulation. Particularly, the discharge pipe 35 provided in the discharge portion 30 protrudes toward the center of the storage space S, thereby inducing the suction and discharge of the medicine to be performed at farther distant positions.

As described above, the medicines are not stirred and circulated, so that sediment is not generated, and the operational reliability of the control apparatus is improved. On the other hand, when the medicines in the storage space S are exhausted, the sensor unit senses this and the circulation pump 21 is no longer operated.
