The seeding device according to the embodiment is a device that is attached to a scattering device carried by a drone and sows seeds in rows in a field. This seeding device, together with the drone, constitutes a seeding system. The configuration of the seeding device will be described in detail with reference to FIGS. 1 to 3. Hereinafter, the configuration of the seeding device according to the embodiment will be described in detail using an example in which the field is a rice field and the seeds are rice seeds.

FIG. 1 is a front view of a seeding device 1 according to an embodiment and a dispersing device 2 to which the seeding device 1 is attached. FIG. 2 is an enlarged sectional view of the seeding device 1. FIG. 3 is a cross-sectional view taken along the line III--III shown in FIG.
Note that for ease of understanding, FIG. 1 shows the entire seeding system 100 including the drone 3. Moreover, in FIG. 2, the cross section of the main part of the seeding device 1 is shown, and the guide tube 30 is only partially displaying the cross section. In addition, a cross section of a part of the spraying device 2 is also shown.

As shown in FIG. 1, the sowing device 1 includes a concentrator 10 that is attached to a dispersing device 2 and collects the rice seeds sown by the dispersing device 2, and a plurality of distribution pipes that are provided in the concentrator 10 and distribute the collected rice seeds. 20, and a guide pipe 30 that is connected to each of the distribution pipes 20 and guides the distributed rice seed in the dispersion direction.

The concentrator 10 is a member that is attached to a casing 24 that accommodates a disk portion 23 of the dispersion device 2, and that collects rice seeds that are sown around the disk portion 23 as the disk portion 23 rotates.

First, the configuration of the spreading device 2 will be explained. As shown in FIGS. 2 and 3, the spreading device 2 stores the seed rice to be spread, and discharges the seed rice when the shutter 21 at the bottom is opened. hopper 22; a disk portion 23 that is arranged below the hopper 22 and is rotated by a drive device (for example, a motor) not shown to scatter the seed rice supplied by falling from the hopper 22 around the outer periphery; The housing 24 has a cylindrical shape that accommodates the portion 23, and has a plurality of openings formed at positions on the cylindrical surface corresponding to the radial direction and the outside of the disk portion 23. As shown in FIG. 3, the disk portion 23 has a plurality of ribs 25 extending radially on the disk surface in order to effectively blow the seed rice around.

The dispersing device 2 has such a configuration, and is conveyed by the drone 3 with the disk portion 23 held horizontally, thereby dispersing rice seeds to the front, rear, left and right sides of the device. However, the dispersing device 2 cannot perform row sowing as it is because the disc portion 23 widely scatters the seed rice in the front, rear, left, and right directions of the device. Therefore, the seeding device 1 is provided with a concentrator 10 that once collects the seed rice scattered by the disc portion 23 of the spreading device 2 in order to perform row sowing.

The concentrator 10 has a substantially toric shape. In other words, it has a substantially cylindrical shape with a height smaller than its diameter and an open bottom and top surface.

In detail, as shown in FIG. 2, the concentrator 10 has a cylindrical surface portion 11 and an end portion of the cylindrical surface portion 11 in the direction of the cylindrical axis A1, that is, from an upper end and a lower end in the vertical direction in FIG. It has annular plate portions 12 and 13 extending inward. As shown in FIGS. 2 and 3, the cylindrical surface portion 11 has a radius R2 larger than the radius R1 of the cylinder of the housing 24 included in the spraying device 2, and the annular plate portions 12 and 13 have a radius It has a width W1 that is approximately the same as the difference between R1 and R2. Further, the cylindrical surface portion 11 and the annular plate portions 12 and 13 are made of a flexible material and can be elastically deformed. As a result, the housing 24 of the dispersion device 2 can be fitted into the substantially cylindrical concentrator 10 inside. The concentrator 10 is attached to the dispersion device 2 by fitting the housing 24 of the dispersion device 2 inside the cylinder.

As described above, in the concentrator 10, the radius R2 of the cylindrical surface portion 11 is larger than the radius R1 of the housing 24 of the dispersion device 2. As a result, the cylindrical surface portion 11 of the concentrator 10 surrounds the outer periphery of the casing 24 of the dispersing device 2, and faces the outer circumferential surface of the casing 24 of the dispersing device 2, separated by an internal space. As a result, the cylindrical surface portion 11 of the aggregator 10 receives the rice seeds that the scattering device 2 scatters around the outer circumference of the housing 24, and moves the rice seeds in the inner circumferential direction while bouncing the rice seeds back and forth between it and the outer circumferential surface of the housing 24. let Thereby, the aggregator 10 aggregates the seed rice between it and the casing 24 of the spreading device 2.

On the other hand, a plurality of through holes 14 are formed in the cylindrical surface portion 11 of the aggregator 10 in order to distribute the aggregated rice seeds.

As shown in FIG. 3, the through holes 14 are formed at equal distances in the circumferential direction of the cylindrical surface portion 11. In other words, they are formed at equal angles around the cylindrical axis A1 of the cylindrical surface portion 11. Specifically, a total of four through holes 14 are formed, and they are arranged at every 90° around the cylindrical axis A1. As described above, the cylindrical surface portion 11 receives the seed rice spread by the spreading device 2 and moves it along the inner circumferential direction. The through hole 14 penetrates from the inner circumferential surface of the cylindrical surface portion 11 to the outer circumferential surface. As a result, the through-hole 14 allows the seed rice collected between the cylindrical surface portion 11 and the housing 24 of the spreading device 2 to pass therethrough. Thereby, the seed rice is distributed to each of the through holes 14.

An end portion of a distribution pipe 20 (also referred to as a pipe joint) is inserted into each of the through holes 14 . Thereby, the seed rice distributed to each of the through holes 14 is distributed to the distribution pipe 20. Note that the hole formed by the through hole 14 and the inner wall of the distribution pipe 20 is an example of a through hole in the claims.

On the other hand, the other end of each of the distribution pipes 20 is connected to a corresponding guide pipe 30 for guiding the seed rice, as shown in FIG.

The guide tubes 30 extend once from each of the distribution pipes 20 in the radial direction and outward of the cylindrical surface portion 11 of the concentrator 10 , and then are bent and extend below the concentrator 10 . The ends of the guide tubes 30 extending below the concentrator 10 are arranged in a straight line. Specifically, they are arranged straight in the left and right direction. Further, the extended ends of the guide tubes 30 are arranged between the rows in which the seed rice is to be sown, that is, at a pitch P1 between the rows. As a result, these guide pipes 30 guide the rice seeds supplied from the corresponding distribution pipes 20, and sow the rice seeds from their ends at the pitch P1 between the rows. As a result, the sowing device 1 is transported by the drone 3 and moves over the rice field F, thereby sowing the seed rice in rows. Also, multiple rows are formed at the same time by sowing seed rice.

Note that the guide tubes 30 are fixed by a frame 31 shown in FIG. 1, so that they are arranged at a pitch P1. It is preferable that this frame 31 is provided with a position adjustment mechanism, and the position adjustment mechanism can adjust the position of the guide tube 30 according to the size of the pitch P1 of the stripes to be formed.

Moreover, it is desirable that the drone 3 flies with the arrangement direction of the guide tubes 30 perpendicular to the traveling direction and the vertical direction during the seeding operation. This is because, with such an orientation, it is possible to sow in rows at the pitch P1 of the arrangement of the guide tubes 30.

As described above, in the seeding device 1 according to the first embodiment, the distribution pipe 20 is inserted into the plurality of through holes 14 formed in the cylindrical surface part 11, and each through hole 14 allows the seed rice to pass through the aggregator. The seed rice aggregated by 10 is distributed to each of the through holes 14. Each end of the plurality of guide pipes 30 is connected to the corresponding distribution pipe 20, and the other end of each of the guide pipes 30 is arranged at the pitch P1 of the rows in which the rice seeds in the rice field F are to be sown. As a result, the seeding device 1 can perform row sowing from above by being transported by the drone 3.

Moreover, in the seeding device 1, since the seed rice is sown in rows from the other ends of the plurality of guide tubes 30, it is possible to form a plurality of rows at the same time.

Further, the seeding device 1 has a structure in which the cylindrical housing 24 of the dispersing device 2 is surrounded by the cylindrical surface portion 11 and the annular plate portions 12 and 13 of the concentrator 10. Therefore, in the seeding device 1, the dispersing device 2 can be easily attached to the concentrator 10 by fitting the housing 24 into the internal space formed by the cylindrical surface portion and the annular plate portions 12 and 13. As a result, the seeding device 1 can easily convert the spreading device 2 into a row sowing device.

Although the seeding device 1 and the seeding system 100 according to the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments.

For example, in the embodiment described above, a total of four through holes 14 are formed and are arranged every 90° around the cylindrical axis A1. However, the present invention is not limited thereto. In the present invention, the seeding device 1 only needs to form a plurality of rows by sowing seeds once, so the number of through holes 14 that are the same as the number of rows should be formed in the cylindrical surface portion 11. good. Therefore, for example, the number of through holes 14 may be two or three, or five or more. The seeding device 1 only needs to have the same number of through holes 14 as the number of rows to be formed.

Further, in the embodiment described above, the distribution pipe 20 is inserted into the through hole 14. However, the present invention is not limited thereto. In the present invention, the distribution pipe 20 may be omitted and the guide pipe 30 may be directly connected to the through hole 14. In this case, since the plurality of through-holes 14 fulfill the function of distributing the seed rice, the plurality of through-holes 14 may be called a distributor.

In the embodiment described above, the sowing device 1 sows rice seeds in the rice field F. The rice field F is flat. Also, the seeds that are sown are rice seeds. However, the present invention is not limited thereto. The present invention is generally applicable to sowing seeds in fields. Therefore, in addition to sowing in rows on flat land, it can also be applied to sowing in rows by creating furrows in the field.
