Description

Drone device with artificial moisture and direct sowing function {ARTIFICIAL AND APPARATUS FOR DIRECT SEEDING USING DRONE}

The present invention relates to a drone attachment device that enables artificial pollination and direct sowing using a drone, and more particularly, a device capable of performing two tasks with one drone attachment device in an agricultural environment that becomes more difficult due to the aging of the agricultural population and unusual weather conditions. to be .

If the weather for pollen fruit trees is not good during the flowering period or if the firefighting insects are not active, the fruit will be poor. This is a situation that is gradually becoming more serious due to unusual weather conditions. In order to overcome this, pollen is applied to the pistil of the fruit tree with a cotton swab so that the fruit can be fruited well. This is called artificial pollination. Artificial pollination is a work that can only be done when many manpower are intensively supplied in a short period of time. Artificial insemination as a conventional prior art was carried out by dragging a complicated and heavy machine or carried on the shoulder like a person spraying pesticides. The case of direct wave is very similar to the above.

In the case of conventional rice farming, a plastic house was made, rice seeds were planted on a plate, and the rice was planted with a rice transplanter. However, with the development of research and technology on direct

Direct sowing is also emerging as one of the farming techniques. Direct seed cultivation can omit the process of planting rice in paddy fields, which has the effect of reducing labor and working hours. The artificial pollination devices of the prior art have many inconveniences due to excessive waste or clogged holes due to excessive spraying of flowerpots.

The present invention is an economical and efficient drone attachment device by making it possible to perform two functions as one drone attachment device in order to solve the problems of the prior art.

In the case of artificial pollination, the existing prior art sprayed pollen by mixing it with water in a medicine container, blown the pollen powder with a blower, or directly applied a cotton swab or ostrich hair to the pistil. The present invention is a device that allows two functions by replacing only the lower part of the stirring tube attached to the drone when working with direct wave or artificial moisture with a drone.

The problems of the prior art of the existing artificial pollination are as follows. Blowing artificial pollinator uses a pollen extender to use limited pollen pollen, but until now, it is used by mixing lycopodite, skim milk powder, starch powder, etc. , however, there is a problem in efficiency as the increased pollen is sprayed out, and there have been some reports of a phenomenon in which the extender and pollen are separated due to the difference in density between substances due to small vibrations. The same is true for mixing the flowerpot with water in the medicine container. Flowers have the ability to fertilize from the day of flowering to 4 days, and are sensitive to surrounding environments such as excessive high temperature, low temperature, humidity, yellow sand, and dryness.

It is mixed with water and the germination rate may decrease depending on the working time. It may adversely affect pollen that is sensitive to temperature and humidity.

Artificial pollination or direct planting with drones has not yet reached its infancy, and even relevant institutions are not able to provide accurate scientific evidence or statistics. However, it is clear that drones do a lot of work, and drones in agriculture in the future are agricultural machines. Many existing artificial pollination prior technologies have been prepared to overcome the shortage of manpower caused by aging, but scientifically clear statistics on efficiency are now required.

In the present invention, in order to improve the above problems, a compromise type of the blowing type and the water injection type was combined in artificial moisture. The blower type in the prior art made the pollen sprayed by separating the strong pressure air flow with a separate device, but in the present invention, the rotational motion of the motor is converted into a reciprocating motion to automatically cause the pollen to fall from the agitator. Pollen falls in a whirlwind with the descending wind of the drone propeller 103 and moisture is formed in every corner. While the pollen is falling, the water in the drone medicine container is separately sprayed through the nozzle 105.

Using a 0.2mm fog nozzle, which has a smaller nozzle diameter than that used for spraying pesticides, prevents pollen from flying far to the side with fine particles and protects the pistil from drying, helping to achieve good artificial pollination.

The present invention is a device that attaches a stirring barrel 111 to a drone and makes flower pots fall from the stirring barrel. It can spray a large area at once, so it has the characteristic of intensively blooming. It has the effect of helping rural reality where it is difficult to obtain many people at once. Also

The lower part of the stirrer 112 is designed to be replaceable, so it is economical to replace the lower container with a large hole in the case of direct seeding.

Figure 2 is a lower detail view for replacement of the figure.

Drone direct sowing and artificial pollination device according to the present invention is a device that can be used in common by replacing only one stirring barrel 111 with pollen for artificial pollination and direct sowing seeds at the lower part of the stirring barrel 112.

The accompanying drawings will be described as follows. 1 is an overall view of the present invention. The stirring barrel motor 109 is a DC motor, which makes the crankshaft rotational movement in a straight line, and the reciprocating shaft 108 moves up and down to push and drop seeds or pollen in the stirring barrel. The amount of dropping is controlled by the speed of the motor 109 and the flying speed of the drone. The speed of the dc motor is controlled by the motor driver. The stirring screw 116 is non-fixed to the reciprocating shaft 108 and is detachable. The end of the reciprocating shaft 108, a silicon pad 114 shaped like a rice bowl upside down, acts as a discharge passage and clogging of the material in the stirring barrel 111, and the stirring screw 116b is a soft material, and the It pushes and expels the material. Controlled by a reciprocating shaft 112 .

2 is a detailed view of the lower part for replacement of the above drawing. The upper stirring barrel 111 and the lower stirring barrel 112 are coupled in a concave-convex shape 115, and the lower barrel can be replaced according to the working method. Pollen pollen spray and water are separately sprayed through the nozzle 105 at the same time. Set the artificial pollination area range with the camera 107 attached to the drone. Since the orchard during the flowering period blooms at the same time, only the range is set and then artificial pollination is performed. The nozzle 105 is sprayed with an appropriate humidity for female flowers. It helps moisture and limits the pollen spraying range to prevent wastage of pollen.

In the case of direct sowing of seeds, remove the pest control container attached to the back. Seeds are also heavy and do not require water. To directly sow rice seeds with a drone, use a laser leveler to level the rice fields and use iron-coated rice seeds. The newly developed iron-coated rice seed was compensated for the weakness of rice seed loss due to algae and light rooting, which were pointed out as existing shortcomings. For rice seeds coated with iron, 5 kg of rice seeds per 300 pyeong is suitable. The flight speed and the amount of emissions should be calculated in advance for the test flight. The biggest advantage of direct sowing of drone rice is labor reduction. In the conventional method, the farmer carried the fertilizer spreader on his shoulder and sprayed it. It can be done in 20 minutes if it is planted directly with a drone based on a paddy field of 3,000 pyeong.
