Abstract

PURPOSE:To sprinkle stably and accurately the titled chemicals, etc. by providing balance mechanisms at the front and the rear of a remote-controlled helicopter, hanging a lengthwise lever and a widthwise lever below the main body, connecting a shock absorber to the lengthwise lever and equipping a sprinkler to the widthwise lever. CONSTITUTION:In the method of sprinkling from the sky by a remote-controlled helicopter, the first balance 4 and the second balance 5 of suitable length are furnished on the main body 1b at the front and the rear and at right angle to the body and balanced. Besides, a lengthwise lever 6 is interposed between lower balances 4c and 5c, a shock absorber 7 provided on the body 1b side is connected to the end part, a hanging ring 12 of the lower balance 5c is furnished to fix a widthwise lever 13 and various sprinklers are fixed to the central position of the lever 13. Accordingly the vibration of the main body 1b is not directly transmitted to a housing 15, a sprinkler 14 is always kept in a horizontal position by the lengthwise lever 6 and agricultural chemicals and seeds are sprinkled from an extremely low and stabilized altitude.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for stably dispersing chemicals, fertilizers, seeds, etc. from the air using a remote control helicopter.

Conventionally, aerial spraying of chemicals, fertilizers, seeds, etc. has been carried out exclusively by helicopter or light aircraft, which is expensive. Moreover, it is not something that can be easily done as needed.

In view of the above points, the present invention uses a remote control helicopter so that spraying can be carried out easily and inexpensively at any time, and also enables accurate spraying to be carried out in a stable condition.

Hereinafter, an example of implementing the present invention will be described based on the accompanying drawings. Fig. 1 is an overall perspective view of the remote control helicopter used in the present invention, Fig. 2 is an extracted view of only the balancing mechanism for keeping the spreader in a horizontal state, and Fig. 3 is an illustration of the shock applicator bar. The partial sectional view, FIG. 4, is a scattering state diagram.

I is a remote control helicopter, 1a is a rotor, l
'l) has a built-in engine that drives the rotor 1a in the main body of the aircraft, and is remotely controlled by a radio (not shown). 1C is a landing gear for takeoff and landing.

Although the configuration described above is the same as that of a conventional remote control helicopter, the present invention allows various types of spreaders to be attached to the fuselage main body 1b via a balancing mechanism, which will be described below.

That is, reference numeral 8 is a balancing mechanism, and the first balance 4 and the second balance 5 of appropriate lengths are installed in the horizontal direction at two right angle positions in the front and back, which are separated by an appropriate distance on the main body lb. Each balance 4.5 consists of a pair of upper and lower balances, and specifically, hanging strings 4b, 5b of a certain length are suspended from both ends of the upper balances 4a, 5a, and the lower balances 4c, 5c are held in a horizontal state. The lower take-up levers 40 and 50 are connected in a parallel link state via a vertical rod 6. At this time, the tail of the rod 6 is made to project slightly to the rear of the balance 5C, and the end The section is connected to a shock absorber 7 provided on the fuselage side 1b. Shock absorber 7
is an air set consisting of a bellows tube 8 made of rubber-like elastic material, and is provided in a case 9 fixed to the body lb side. IO is a suspension rod that is hung from the bellows pipe 9 and projects a certain length downward from the casing 9 so that the lower end of the 1" flO and the rear end of the vertical rod 6 are connected. (See Figure 3) On the other hand,
A pair of fishing rings 12a, 121) are provided on the lower balance 5C so that a relatively long horizontal rod 13 can be attached thereto.
is fixed via the case 15. The illustrated example is a powered crop duster, and the engine is turned on and controlled via a receiving antenna (not shown). Reference numeral 16 denotes an ejection pipe, which is horizontally attached to the lower part of the main body, and is provided with a large number of ejection holes at appropriate intervals in the length direction. These crop dusting machines 14 are similarly operated by receiving commands via radio.

- In the above, the horizontal rod 13 utilizes Yajirobee's balance principle, and the horizontal rod as a counterbalance rod is made to have the necessary constant length, which is approximately 2 meters in size. There is. Further, the shock absorber 7 is for absorbing vibrations, and is not limited to the air absorber shown in the illustration, but may be one using a spring.

Next, to explain the aerial spraying, as shown in FIG. 4, the altitude of the remote control helicopter 1 is gradually increased by controlling the radio device 17.

At this time, whether or not the aircraft is flying at a predetermined ascent angle is determined by an elevation angle measuring device 18 installed on the ground. That is, the table stand tSa is set at a certain angle, and the table is flown so that it looks through both measuring rings (1ga, 19k) provided on the plate and is captured within both rings, and the distance l is measured. By doing so, the altitude H at that time can be calculated, and aerial spraying can be performed at the target altitude H (usually 10 m to 500 α).

In the present invention, the balances 4a, 5b, etc. are held elastically using piano wire. This prevents the vibration of the fuselage body lb from being directly transmitted to the casing 15, and on the other hand, the vertical rod 6 with the shock absorber 7
This is extremely effective in keeping the spreader 14 in a stable and good horizontal state at all times.

According to the present invention, it is possible to not only spray pesticides at targeted locations (controlling pine beetle insects, etc.), but also spray pesticides, fertilizers, and sow seeds in large fields at extremely low altitudes and in stable conditions. Moreover, it can be done simply and easily as needed, and it can be done at low cost.

In the present invention, the ejection pipe is replaced with a spray pipe in order to spray the liquid. For sowing seeds, etc., a spout pipe with a built-in screw is used.
