[0001] METHOD AND APPARATUS FOR DIRECTLY SOWING SEEDS USING AIRCRAFTS [0002]

The present invention relates to a method and apparatus for directing a seed using a flying body flying in the air.

Generally, rice growing is done either by raising seedlings directly or by growing seedlings purchased through seedlings to cultivated areas.

In recent years, as the size of rice farming has become larger and the farming method has become more mechanized, the number of farmers applying the direct method has been increasing.

Korean Patent Laid-Open Publication No. 10-2014-0081704 discloses a direct shear wave machine in which sowing is carried out in a state in which a medicament for controlling insect pests can be effectively applied. However, there is a problem in that it is difficult to perform a rapid direct wave due to the nature of being pulled by a vehicle moving along the ground.

Korean Patent Publication No. 10-2014-0081704

The present invention is to provide a method and apparatus for directing seeds using a flying body flying in the air.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed. Other objects, which will be apparent to those skilled in the art, It will be possible.

The present invention provides a method of directing air to a land, comprising the steps of: And a step of flooding the seeds by floating the airplane on which the seeds are placed above the fresh-watered land.

The airborne wave rectifier of the present invention comprises: a mounting part mounted on a flying body; A storage unit installed in the mounting unit and storing seeds; And a dropping unit for spreading the seed toward the land in a state where the flying body is in flight, and the dropping unit can adjust the amount of the seeds to be discharged in accordance with the moving speed of the flying body.

The method and apparatus of the present invention can direct the seed using a flying body, and therefore, it is possible to work very quickly.

By forming a ridge on the target land and performing fresh water before directing through the aircraft, randomly seeded seeds can gather into the ridge formed by the ridges by the flow of water. Therefore, since the effect of the seed is sprayed along the furrow, the position of the seed can be controlled by regulating the position of the furrow.

According to the present invention, it is also possible to provide a scattering module for scattering seeds in the air, a means for pneumatically pressurizing seeds to be loaded on a foot extending toward the land, etc. According to the present invention, . Also, seeds can be stuck in the ground.

In addition, a seed module having an annular shape may be provided for protecting the seed at the time of dropping and for growing the dropped seed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a flow chart illustrating an airborne direct wave method of the present invention.

The air navigation method shown in FIG. 1 can be largely divided into two steps (S 510, S 520).

First, the first step S 510 may be a step of generating and desiccating the land 91 on the land 90 to be subjected to direct wave. Lee (91) means a place made by plowing rice paddy fields and rolling up soil. Briefly, the paddle 91 may mean a point that is projected higher than elsewhere on the ground. In the course of forming the gutter 91, a lower trough 93 may be formed which is relatively lower than other portions of the ground.

The height of the ridge 91 formed in the land 90 may be 5 cm to 10 cm from the ridge 93 in the direction opposite to the gravity direction.

The fresh water contains water in the land (90), and the depth of the fresh water can be greater than the height of the ridge (91). Therefore, in the land 90 where the fresh water is completed, the ridge 91 can be kept in a water-immersed state.

When the generation of the rinse (91) and the desalination are completed, a two-step process can be performed.

The second step (S 520) may be a step of spreading the seeds 10 by floating the flying object 190 on which the seeds 10 are placed above the target.

At this time, the flight body 190 may include a manned flight body 190 on which the pilot is boarding, and a unmanned air vehicle body 190 on which the pilot is unfit. The flight body 190 is preferably a unmanned aerial vehicle 190 in order to reduce the direct wave cost and to freely adjust the direct wave period.

The flight body 190 can evenly spray the seeds 10 to prevent the seed 10 sprayed on the flight body 190 from being concentrated in a certain area and this process may be equivalent to ' have.

Fig. 2 is a schematic diagram showing the airborne direct wave method of the present invention.

The seed 10 scattered on the land 90 by the air body 190 can be settled in water and placed on the floor. At this time, the bottom may be the ridge 91 or the valleys 93. Then, the seed 10 placed on the ridge 91 by the flow of water can be naturally led to the valleys 93. [ In addition, the seed 10 located in the trough 93 can be naturally covered by the soil because the troughs constituting the trough 91 collapse due to the flow of water to cover the trough 93. In the case of the fresh water, the seeds are transferred to the furrows by the flow of water and the furrows are covered with the furrows when the height of the furrows is less than 5cm. On the contrary, if the height of the ridge exceeds 10 cm, the amount of water to be desalinated becomes large, and the adverse effect that the growth of the seed is suppressed is likely to appear. Therefore, the height of the ridge is preferably 5 cm or more and 10 cm or less on the basis of the valleys.

The seeds 10 sprayed from the air body 190 are preferably seeds 10 that are slightly buds for the purpose of promoting germination and growth in rice, barley, peanuts, branches and the like. In the case of direct wave, it may be difficult for the seed 10 to be planted at a position optimized for growth of the seed 10. Therefore, the seed seed 10 which is easy to grow even if the surrounding environment is somewhat weak is suitable.

As described above, according to the airwave direct wave method of the present invention, after forming the ridges 91 in the land 90 and draining the water, the direct wave process can be completed by directing to the air vehicle 190. Further, the seeded seed 10 can naturally be covered with soil.

Therefore, rapid direct wave is possible. In addition, since the seeded seed 10 is covered with soil, it can help the growth of the seed 10. In addition, when the unmanned vehicle 190 such as a drone or an unmanned helicopter capable of steerable by the user performing the direct wave is provided, the direct wave cost may be lower than the direct wave caused by manual operation or the direct wave using the ground vehicle.

For direct wave, the flight body 190 may have a special structure. Hereinafter, the aerial duplexer centering on the air vehicle 190 will be described.

3 is a schematic view showing an air wading apparatus according to the present invention.

3 may include a mounting portion 110, a storage portion 130, and a dropping portion 150.

The air waving device of the present invention may include a mounting portion 110 that is detachable from the air body 190. Since the storage unit 130 and the drop unit 150 are connected to the mounting unit 110, when the mounting unit 110 is mounted on the air vehicle body 190, the storage unit 130 and the drop unit 150 are also connected to the mounting unit 110 The state mounted on the air vehicle 190 can be maintained.

The storage unit 130 is installed in the mounting unit 110 and the seed 10 can be stored. The storage unit 130 may have a tubular shape in which the seeds 10 are stored.

If the seed 10 stored in the storage unit 130 is randomly scattered on the land 90, a large amount of the seed 10 is scattered at a specific position of the land 90, . That is, according to the random release of the seed 10, it is difficult for the seed 10 to be uniformly sprayed on the land 90. This problem can be solved by the dropper 150.

The dropping part 150 can spray the seed 10 toward the land 90 while the air vehicle 190 is flying.

At this time, the dropping unit 150 can adjust the amount of the seed 10 to be discharged according to the moving speed of the flying body 190.

A discharge port 150 may be provided with a valve (not shown) for opening and closing a flow channel through which the seed 10 is output to regulate the number or amount of the seeds 10 to be discharged toward the land 90, . At this time, the discharge unit 150 can control the opening area of the flow path through the control of the valve.

For example, if the moving speed of the flying object 190 flying horizontally on the ground is high, the dropping part 150 can increase the open area. If the open area is increased, the number of seeds 10 output per unit time can be increased.

As another example, the dropper 150 can reduce the open area if the moving speed of the air vehicle 190 is slow. When the open area is small, the number of seeds 10 output per unit time can be reduced.

For example, assume that 100 seeds (10) are 10 m long along a horizontal x-axis on the ground. It is recommended that 10 seeds per 1 m be sprayed so that 100 seeds (10) are evenly spread over a length of 10 m.

In fact, the direct wave can also be made in the direction of the y-axis orthogonal to the x-axis depending on the extent to which the seed 10 is scattered in the above direct wave process. For convenience of description, the number of seeds 10 scattered along the y-axis is ignored.

When the flying body 190 moves at a speed of 2 m per second along the x-axis direction, it is preferable that the seeds 10 stored in the storage unit 130 are output at a rate of 20 per second. At this time, the dropping unit 150 can adjust the opening area of the valve so that the seeds 10 are output at a rate of 20 per second.

If the flying object 190 moves at a speed of 1 m per second, the dropping unit 150 can adjust the opening area of the valve so that the seed 10 is output ten times per second.

As described above, according to the dropping unit 150 of the present invention, the set number of seeds 10 per setting area can be sprayed irrespective of the moving speed of the air body 190. That is, according to the present invention, when the amount of seed (10) to be delivered per unit area is determined, the dropping part (150) can adjust the opening area of the channel through which the seed (10)

Unlike the ground moving vehicle, the flight body 190 is not easily controlled in speed. In particular, if the driver of the air vehicle 190 is a farmer, speed control may be very difficult due to insufficient driving. In this situation, if a certain number of seeds 10 are dropped per unit time regardless of the speed of the air vehicle 190, a large number of seeds 10 are scattered in some regions, and heterogeneous direct waves in which a small number of seeds 10 are scattered in other regions .

The nonuniform direct wave can act as a factor that makes it difficult to introduce the direct wave method using the flight body 190. However, according to the dropping unit 150 of the present invention, even if the speed of the flying object 190 is varied due to the immaturity of the operation or wind or the like, the drop amount per unit time is adjusted in accordance with the variable speed, Can be maintained constant. Therefore, the direct wave can be uniformly applied to the land 90, so that the direct wave efficiency can be improved. It is clear that the improvement of the direct wave efficiency will speed up the introduction of the direct wave.

The seeds 10 output from the dropping unit 150 may be plural at one time. If a plurality of seeds 10 at this time are dropped at the same point of the land 90, the nonuniformity of the direct wave tends to occur. Therefore, even if a plurality of seeds 10 are dropped from the dropping unit 150 at the same time, it is necessary to cause a plurality of seeds 10 to be discharged to different points on the land 90.

4 is a schematic view showing another air waving device according to the present invention.

A scattering module 151 and a valve (not shown) may be provided in the dropping unit 150 so that the seed 10 is evenly discharged to the land 90.

The scattering module 151 can scatter the seed 10 so that the seed 10 output toward the land 90 is scattered.

For example, the scatterer module 151 may include an output tube 152 through which the seed 10 passes, and a rotating part (not shown) that rotates the output tube 152. At this time, the output tube 152 may be formed to be bent in a direction different from the direction in which the end facing the paper surface faces the paper. The direction of the seed 10 output through the bent end in the plane of the output tube 152 fluctuates in accordance with the rotation of the output tube 152 so that even if a plurality of seeds 10 are output at the same time, The seeds 10 can be dropped at different positions on the land 90. [

The projection angle b of the seed 10 can be determined according to the degree of bending of the end of the output tube 152. [

The throw angle b is a fixed value, while the delivery range c of the seed 10 output through the output tube 152 can be varied. For example, the delivery range ⓒ formed on the ground increases as the distance between the flight body 190 and the ground increases, and decreases as the distance between the flight body 190 and the ground decreases.

It is advantageous that the number of seeds 10 to be subjected to direct shearing per unit area of the land 90 is constant even if the dropping range C is varied. The valve can be used so that the number of seeds 10 remains constant irrespective of the fluctuation of the delivery range c.

The valve can open and close the flow path of the seed 10 moving from the storage part 130 to the scattering module 151. [ The dropping part 150 can control the opening area of the flow path through the control of the valve.

The valve can increase the open area when the air body 190 rises and reduce the open area when the air body 190 falls. In other words, the amount of the seed 10 to be discharged is increased when the delivery range ⓒ is increased due to the rise of the air body 190, and the delivery amount of the seed 10 is decreased when the delivery range ⓒ is decreased due to the descent of the air body 190. Thus, the number of seeds 10 sprayed per unit area on the basis of the land 90 can be kept constant.

On the other hand, the seed 10 dropped from the dropping section 150 may be vulnerable to wind due to its light weight. For example, the seed 10 dropped at the second position while being expected to be dropped at the first position of the land 90 may be discharged to the first position by the wind caused by the weather change or by the wind caused by the propeller of the air vehicle 190, It can be dropped at a position different from the position. In other words, the seed 10 dropped to the first position can reach the position different from the first position by the wind.

The seed module 20 can be used so that the seed 10 dropped to the first position can reach the first position.

5 is a cross-sectional view showing the seed module 20.

When the seed module 20 is provided, the dropping part 150 can spray the seed module 20 instead of the seed 10. The seed module 20 may include a seed 10, a fertilizer layer 21 surrounding the seed 10, and a starch layer 23 surrounding the fertilizer layer 21.

The fertilizer layer 21 may contain fertilizer necessary for the growth of the seed 10.

The starch layer 23 may comprise starch that surrounds the fertilizer layer 21. The starch layer 23 may form the contour of the seed module 20. Starch melts on contact with water and has a hard nature when dried. In addition, the starch layer 23 may be formed into a spherical shape.

Therefore, according to the seed module 20 including the spherical starch layer 23, the weight is increased as compared with the seed 10, so that it is less influenced by the wind. Also, due to the spherical shape, it can be less influenced by the wind. As a result, the seed module 20 dropped toward the first position of the land 90 can be accurately dropped to the first position.

In addition, the seed 10 can be protected because impact applied upon dropping or ground contacting is applied to the starch layer 23 instead of the seed 10. Since the impact transmitted from the starch layer 23 to the seed 10 is absorbed in the fertilizer layer disposed therebetween, the seed can be reliably protected from external impacts.

The seed module 20 dropped on the land 90 can be contacted with the fresh water. When the starch layer 23 melts due to contact with water, the fertilizer layer 21 disposed inside the starch layer 23 may melt in water and the seeds 10 may contact the land 90.

On the other hand, if the seed 10 or the seed module 20 dropped at the dropping part 150 is fired at a higher rate of firing, the fired seed 10 or the seed module 20 can be stuck in the ground. Seeds (10) embedded in the ground can be beneficial for growth.

A method for increasing the firing rate of the seed 10 or the seed module 20 may be provided.

6 is a schematic view showing another airborne wave director apparatus of the present invention.

6, a dropping unit 150, a pressing module 155, and a guide module 157 may be provided on the dropping unit 150.

The feet 153 may extend in a first direction and include a flow path in which the seeds 10 or the seed modules 20 flow along the first direction. The first direction may be a direction toward the ground.

The pressure module 155 may provide pneumatic pressure to the foot 153 along the first direction.

The seed 10 or the seed module 20 loaded in the foot 153 can be fired strongly in the first direction by the air pressure provided from the pressure module 155. [ The seed 10 or the seed module 20 fired from the footstep 153 moves at a high speed and is less affected by the surrounding wind or the like and can arrive at the target position accurately. And, if the land 90 is submerged, it can penetrate the surface of the land 90. Seeds 10 that have penetrated the interior of the land 90 may be covered with soil.

A guide module 157 may be used to launch a plurality of seeds 10 or seed modules 20 stored in the storage unit 130.

The guide module 157 may include a flow path for guiding the seed 10 of the storage part 130 to the feet 153. One end of the guide module 157 may be connected to the storage unit 130 and the other end of the guide module 157 may be connected to the side of the foot 153. Further, the guide module 157 may extend along a second direction inclined in the first direction. At this time, the second direction may be a direction in which the position of the guide module 157 connected to the side of the feet 153 is lower than the position of the guide module 157 connected to the storage unit 130.

According to the guidance module 157, the seed 10 or the seed module 20 stored in the storage unit 130 can be moved along the guide module 157 and loaded in the foot 153.

A stopper 159 may be provided on the dropping part 150 to prevent the seeds 10 or the seed module 20 loaded on the footing 153 from dropping due to their own weight before the air pressure is applied.

The stopper 159 may be installed on the foot 153 so as to be movable in a direction perpendicular to the first direction. One end of the stopper 159 may be provided with an elastic portion for pushing the stopper 159 in a direction perpendicular to the first direction. The stopper 159 can maintain a state in which the stopper 159 blocks the flow path of the foot part due to the pushing out of the elastic part.

The seed 10 or the seed module 20 introduced into the foot body 153 via the guide module 157 is restricted by the stopper 159 protruding into the foot body 153 by the elastic portion . In this state, when the air pressure is applied from the pressing module 155, the seed 10 or the seed module 20 can be fired while pushing the stopper 159 toward the wall surface side of the foot 153 by overcoming the elastic force of the elastic part.

The valve and pressure module 155 described above can be driven when the seed release control signal is applied by the user.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
