The seeding device according to the present invention comprises a seed adsorption support portion that supports seed particles by air adsorption and a guide receiving plate for receiving seeds supplied from the seed adsorption support portion and sowing the seeds at a predetermined interval on a seeding bed. Become.

FIG. 1 is an explanatory view showing an embodiment of a seed adsorption supporting device 10. The suction support device 10 is provided on one surface of a main body 12 of a suction support portion formed in a flat plate shape with a suction recess 14 for sucking and supporting the seed grains by suction in accordance with a sowing interval on a sowing bed. It is a thing. FIG.
Here, for convenience of description, the suction concave portion 14 is shown facing upward.

FIG. 2 shows an enlarged structure of the suction recess 14. The suction recess 14 is provided with a suction hole 16 on the inner bottom surface of the suction recess 14 in order to support the seed grains 30 by air suction, and the back side of the suction hole 16 communicates with the air suction passage 18. The air suction path 18 communicates with a vacuum generator 20 provided outside the main body 12. In addition, the suction path 18, the vacuum generating device 20, and a tube connecting these components constitute an air suction unit.

The suction recess 12 is formed to a certain size in order to adsorb and support various kinds of seed grains, and has a smooth bell-shaped inner surface as shown in FIG. This is because when the seed grains 30 are sucked by air, the seed grains 30 are attracted to the inner bottom surface of the suction concave portion 12 (the top portion of the suction concave portion 12 in FIG. 2), and the suction hole 16 opened on the inner bottom surface is set in the seed hole. Grain 30 is blocked and seed grain 3
This is to ensure that 0 is absorbed by air.

If the diameter of the suction hole 16 is set smaller than the size of the seed grain 30, even if a plurality of seed grains 30 are sucked into the suction recess 14, one seed grain 3
0 closes the suction hole 16 and is adsorbed.
As the suction force is no longer applied to
One seed grain 30 is adsorbed by air and supported by the suction recess 12.

FIG. 3 is an explanatory view showing another embodiment of the suction support device 10. As shown in FIG. That is, as shown in FIG. 2, seed grains are sucked and supported one by one in the suction concave portion 14 formed in a bell shape, so that when seeding a plurality of seed grains at one location, the seed grains are sucked one by one. Supporting is inefficient. The example shown in FIG. 3 has two suction recesses 14a at one seeding position,
14b are arranged adjacent to each other. Suction recess 14
The shapes of a and 14b are the same as in the example shown in FIG. 2, the inner surface is formed in a bell shape, and suction holes 16a and 16b are opened in the inner bottom surfaces of the respective suction recesses 14a and 14b.
b is communicated with the air suction path 18.

As described above, if the suction recesses 14a and 14b are arranged adjacent to each other, the seed grains 30 are sucked and supported one by one in each of the suction recesses 14a and 14b. Adsorb and support two seeds in one place,
The seeds can be sown one by one. Of course, the number of suction concave portions arranged adjacent to each other can be further increased to three or four, whereby the number of seeds adsorbed at one time can be increased.

Seed grains 30 adsorbed and supported by suction recess 14
Is the suction recess 1 when the negative pressure by the vacuum generator 20 is released.
Fall from 4 as it is. In this embodiment, the suction recess 14 is used.
By using the guide receiving plate 40 for accurately guiding the seeds falling from the to the sowing position together with the adsorption support device 10, accurate sowing is possible.

FIG. 5 is a perspective view of the guide receiving plate 40. The guide receiving plate 40 is made of a conductive material such as metal to be formed in a flat plate shape in order to prevent electrification, and is provided with a guide hole 42 in accordance with a seeding position. The guide hole 42 has a tapered surface shape with an open upper side, so that the seeds fall from the suction recess 14 in order to accurately guide the seed grains 30 sucked and supported by air suction by the suction support device 10 to the seeding position. In this case, even when the seeds are slightly displaced, or when a plurality of seeds are sucked and supplied at one location as shown in FIG. 3, the seeds can be reliably received by the guide holes 42.

FIG. 6 shows a guide hole 42 provided in the guide receiving plate 40.
It is sectional drawing which expands and shows. The guide hole 42 has a shape in which the seed receiving side is open as described above. A seeding hole 44 is opened at the bottom of the guide hole 42, and the seed that has fallen into the guide hole 42 falls from the seeding hole onto the seeding bed 4 and is sown. Reference numeral 46 denotes a projection provided around the seeding hole 44. At the time of seeding, the projection 46 is placed on the upper surface of the seeding bed 4 and the guide receiving plate 40 is arranged. Since the guide receiving plate 40 is made of a conductive material, the seeds do not adhere to the guide receiving plate 40 due to static electricity or the like, and the seeds can be sown at a predetermined position on the sowing floor 4 reliably.

The operation of actually seeding using the suction support device 10 is as follows. First, the vacuum generating device 20 is operated and air is sucked from each suction recess 14 provided in the suction support device 10 so that the seeds are stored in the suction recess 14. Adsorb and support the grains. The seeds are stored in a container having a fixed area, and the seed particles are easily sucked and supported one by one in the suction recess 14 by bringing the suction support device 10 closer to the container in which the seeds are placed.

Next, while maintaining the negative pressure of the suction recess 14, the suction support device 10 is moved onto the guide receiving plate 40 arranged on the seeding bed 4, and the guide hole 42 and the suction recess 14 are aligned. Then, the air suction of the vacuum generator 20 is released. As a result, the seeds fall from the suction recess 14 into the guide holes 42. When a plurality of seeds are supplied to the guide holes 42, the seed supply operation by the above-described adsorption support device 10 is repeatedly performed, and when a predetermined number of seeds are supplied to each of the guide holes 42 of the guide receiving plate 40. Then, the guide receiving plate 40 is removed. Thus, the seeds are seeded on the seeding bed 4 by a predetermined number at a predetermined interval.

The method of supporting the adsorption of seed grains by the adsorption support device 10 is a method of supporting the seeds by using a negative pressure, and thus is much easier and more reliable than the method of picking the seeds one by one. Seeds can be supplied.
In FIG. 1, the suction recesses 14 are arranged vertically and horizontally on the main body 12 of the suction support device 10. However, as shown in FIG. 4, a plurality of suction recesses 14 are arranged in a row at a predetermined interval. Can also be used. Thus, the suction support device 10
By using both the guide receiving plate 40 and the guide receiving plate 40, it is possible to supply an arbitrary number of seeds for each guide hole 42. Seeding can be performed much more efficiently than the method of putting seeds in each guide hole. Further, in some cases, it is possible to provide a structure in which only one seed suction support position is provided in the main body 12 and the seeds are sequentially introduced into each guide hole 42.

The suction support device 10 and the guide receiving plate 40
Is combined, the suction support device 10 and the guide receiving plate 40 are configured as a pair, and one guide receiving plate 40
However, it is also possible to adopt a configuration in which a plurality of adsorption support devices 10 are simultaneously operated to perform a seeding operation in parallel. This allows more efficient sowing. Also, the seeding operation by the suction support device 10 can be carried out by a method of holding the main body 12 of the suction support device 10 by hand, moving it on the guide receiving plate 40 and seeding the same. By adopting a device configuration in which the device is automatically moved onto the guide receiving plate 40, the device can be used as a device that automatically performs the seeding operation.

[0020]

According to the apparatus for supporting the adsorption of seeds and the seeding apparatus using the same according to the present invention, the sowing operation can be performed very efficiently, and the seeds can be sowed at a predetermined interval without fail. After sowing, the plant grows in a uniform manner, and provides remarkable effects such as easy provision of high quality flowers and vegetables.
