Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medicine spraying device mounted on a radio-controlled helicopter.

[0002]

2. Description of the Related Art Conventionally, there has been known a technique of dispersing a medicine in the air by mounting a medicine spraying device on a radio-controlled helicopter. For example, this is a technique disclosed in Japanese Patent Application Laid-Open No. 7-163223. A drug spraying device mounted on the radio-controlled helicopter includes a tank for storing a drug, a sprayer for spraying the drug in the air, a pipe for guiding the drug from the tank to the sprayer, and a flow rate of the drug. And a gate valve for adjusting the pressure.

[0003]

In the conventional drug spraying device mounted on a radio-controlled helicopter, the flow rate of the drug could be adjusted by a gate valve, but the spray width was single. Therefore, in the case of spraying a medicine, it is necessary to reciprocate repeatedly in a wide range, and in a narrow range, there are many overlapping portions, and the spray is spread in an unnecessary range to waste the medicine or cause harm. Was happening. In order to eliminate this inconvenience, it is necessary to change the spray width by replacing the sprayer, which involves a complicated operation.

[0004]

SUMMARY OF THE INVENTION In a medicine spraying apparatus mounted on a radio-controlled helicopter for spraying medicine in the air, sprayers having different spray widths are provided on the right and left sides of the body, and the sprayers can be operated alone or both. And the spray width can be changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and is described in the present specification and the accompanying drawings. The present invention extends over the whole range of technical ideas truly intended by the present invention. That is, in the embodiment, the explanation will be made using a granule spraying device. However, it is also conceivable to replace the sprayer with a liquid or powder sprayer and apply the liquid or powder to the spraying device.

FIG. 1 is a side view of one embodiment according to the present invention, and FIG. 2 is a front view of one embodiment according to the present invention. In the medicine spraying device mounted on the radio-controlled helicopter shown in FIGS. 1 and 2, the tank 1 for storing the medicine is mounted so as to extend from the lower part of the radio-controlled helicopter 9 to both side surfaces and is mounted on the tank. Ducts 2 and 2 for guiding the stored medicine are communicated with both lower ends of the duct 1.
Spreaders 5A, 5 with opening / closing valves 4, 4 interposed at the lower part of 2
B is connected. Further, a generator mounted on an engine (not shown) is provided inside the fuselage of the radio-controlled helicopter 9, and the power generated by the generator is supplied to a battery (not shown) via a rectifier circuit (not shown). It is stored.

The medicine stored in the tank 1 enters the duct 2 by its own weight, and the medicine introduced into the duct 2 falls through the opening / closing valve 4 and is supplied to the sprayers 5A and 5B.
The opening / closing valves 4.4 are opened and closed by solenoids 4a and 4b, and the solenoids 4a and 4b are connected to a controller C as shown in Fig. 6 and from the ground via a receiver 10 connected to the controller C. The opening / closing operation is performed by the operation of the wireless device 11. Further, in place of the configuration of the opening / closing valves 4, the shutter may be opened / closed by driving a servo motor.

A sprayer 5A is provided below the opening / closing valve 4.4.
5B, two dispersers 5A and 5B are provided on the lower left and right sides as viewed from the front of the fuselage, and the impellers 6A and 6B and the impellers 6A rotatably provided around the vertical axis.
A cover that covers the upper side of the impeller 6B concentrically and a motor 3.3 that rotationally drives the impellers 6A and 6B;
The motor 3 is driven by electric power supplied from a generator via a battery or a rectifier circuit.
The control of the driving of No. 3 is performed by radio control via the controller C.

The impellers 6A and 6B, which are rotationally driven by the motors 3, 3, are configured to discharge the medicine dropped from the duct 2 by rotation in the horizontal direction. The sprayers 5A and 5B may have the cover 7 if necessary.
Is provided around the impellers 6A and 6B from the front peripheral edge of the impeller 6A, thereby restricting the direction in which the medicine is released.

FIG. 3 is a front view of one embodiment of the present invention at the time of operation of one of the spreaders, FIG. 4 is a front view of the other sprayer of the embodiment of the present invention at the time of operation, and FIG. It is a front view at the time of both operation | movement of a spreader in one Example of invention. In FIGS. 3, 4 and 5, the sprayers 5A and 5B are capable of spraying a medicine by switching between simultaneous operation of both and single operation of only one of them, and the operation is controlled via the controller C. It is performed by radio control from the ground. The spray width Wa of the sprayer 5A and the sprayer 5B
Are configured to be different.

Therefore, when the valve is opened and closed by operating or manually operating the wireless device 11 and the sprayer 5A is operated alone, the medicine can be sprayed with a slightly wider spray width Wa as shown in FIG. When the sprayer 5B is operated alone, FIG.
In the case where the medicine can be sprayed in a narrow range of the spray width Wb shown in FIG. 5 and both the sprayers 5A and 5B are operated, the spray width is as shown in FIG. The width becomes Ww, and the medicine can be sprayed. In this manner, the sprayer 5A or the sprayer 5B is selected according to the width around the field or at the last remaining portion, and is sprayed in a narrow range to prevent phytotoxicity around the field. In the central part of the field, both of the sprayers 5A and 5B are operated to spread over a wide range to reduce the work time. The change of the spray width can be easily performed by the wireless device 11, and the work such as replacement of the sprayer is not required.

[0012]

As described above, the present invention has the following advantages. First, since the spreaders with different spray widths were provided on the right and left sides of the body of the radio-controlled helicopter, the desired spray width only needs to be selected, and there is no need to change to a spreader with a different spray width. You can save time. In addition, since the sprayers can be operated alone or both, when spraying over a wide range, both sprayers can be operated to spray the medicine over a wide range, and when spraying over a narrow range, it is desirable to perform spraying over a narrow range. By actuating one of the sprayers having a width of, spraying can be performed, wastefulness due to spraying of excess medicine can be suppressed, and the medicine can be sprayed efficiently. In addition, since the medicine is not sprayed over an unnecessary range, there is no risk of injuring surrounding people or livestock.
