Description

[Technical Field]

[0001] The present invention relates to a seed sowing device for sowing seeds near the top of potting soil in a plurality of pots in a seedling tray. [Background technology]

[0002] Seedling trays are materials for raising large quantities of uniform seedlings from seeds. They consist of a number of pots lined up in rows, and seeds are sown on top of the compacted culture soil filled inside the pots, then covered with soil and submerged in water before use. Conventionally, sowing seeds involves dropping seeds by hand onto the top of the culture medium in a pot, attaching seeds to a wet toothpick or stick and touching the top of the culture medium, or pinching seeds one by one with tweezers and placing them on top of the culture medium, which places a great deal of strain on the nerves, requires long working hours, and is mentally exhausting work. Patent Document 1, which was devised to solve the above problem, is a seed sower that combines a seed sowing plate with circular holes for sieving the seeds and a partition plate through which the seeds fall.By pulling out the partition plate at the top of the pots in the seedling tray, the spherical seeds fall onto the top of the culture soil in the pots and are sown.This has the advantage that a large number of seeds can be sown onto the top of the culture soil in the pots in a short period of time. However, the method involves placing the seeds on a seeding plate, spreading them with a brush to fill all the holes, and then inserting the seeds into the holes. The shape of the seeds to be sown is limited, and they must be spherical and of uniform size. If seeds are not uniform in size, spots will appear in the pots in the seedling tray, and it is not possible to sow seeds that are not spherical or have germinated. Another problem is that it is uneconomical to have to prepare seeding plates for each size of seed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-095320 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made to solve the above problems, and aims to provide a seed sowing device that can sow seeds near the top of the culture soil in pots in a seedling tray, regardless of the size and shape of the seeds, even if they are germinated seeds, and can cover the top with soil and water them from above. [Means for solving the problem]

[0005] The sowing device of the present invention is a sowing device comprising a seedling raising tray in which a number of openings and a number of pots connected to each of the openings are arranged in a regular pattern, and a seed drill having a number of protrusions formed at positions that coincide with the openings of the pots, and is characterized in that by overlapping the seedling raising tray and the seed drill, the protrusions are set to a length that allows the tip of the protrusion on the seed drill to be inserted into the pot through the opening of the pot on the seedling raising tray. The tip of the protrusion is the part to which the seeds are attached, and it is desirable that the protrusion be set to a length that allows the seeds to be sown near the top of the culture soil filled in the pot of the seedling tray. It is desirable that the base of the projection is provided with a support for fixing the projection and a hole for inserting the covering soil into the pot. [Effects of the Invention]

[0006] With the seeding device of the present invention, even if the seeds are in a germinated state, regardless of the size and shape of the seeds, seeds attached to the tip of the protrusion of the seeding device can be sown on top of the culture soil filled in the pot of the seeding tray simply by overlapping the seedling tray and the seeding device, which reduces the effort required for sowing, increases work efficiency, and saves time.

[0007] The invention described in claim 2 uses the tip of the protrusion of the seed sower as the part to which the seeds are attached, so that by overlapping the seedling tray and the seed sower with seeds attached to the tip of the protrusion and covering the top with soil, it is possible to easily sow the seeds on top of the culture soil in the pot of the seedling tray.

[0008] The invention described in claim 3 has a hole in the seed drill for inserting the covering soil, so that the covering soil can be inserted through the hole when the seedling tray and the seed drill are overlapped. This has the effect of allowing the seeds attached to the tip of the protrusion of the seed drill to be sown on top of the culture soil in the pot of the seedling tray, and also making irrigation possible.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The seeding device 1 of the present invention is a device that sows seeds 40 between the culture soil 35 and the covering soil 30 inside the pot 25 by overlapping the seedling raising tray 20 and the seed sower 10, and its structure will be described below.

[0011] The seedling tray 20 is made of synthetic resin and has a structure in which openings and multiple pots 25 connected to each of the openings are arranged in a regular pattern, as shown in Figure 1. As shown in the enlarged view of Figure 2, each pot 25 has an opening 22 at the top and a drainage hole 28 at the bottom, and the inside is filled and compacted with a certain amount of potting soil 30, as shown in the longitudinal cross-sectional view of Figure 5.

[0012] The seed sower 10 is made of synthetic resin and has a structure that overlaps with the seedling raising tray 20 as shown in FIG. 3, and has a protrusion 15 formed at a position that coincides with the center position of the opening 22 of the pot 25. The projections 15 are erected on the support 13 as shown in the enlarged perspective view of part B in Fig. 4, and have a plurality of holes 18 at their bases for inserting the soil cover 30. The length of the projections 15 is set to be at least long enough to reach the top of the culture soil 30 as shown in the longitudinal cross-sectional view of the inside of the pot 25 in Fig. 6. Furthermore, the tip 17 of the projections 15 is the part that attracts the seeds 40, and may be made of a synthetic resin with electrostatic adsorption properties.

[0013] Hereinafter, a method for using the seeding device 1 of the present invention will be described. As a preliminary preparation, the seedling tray 20 is filled with an appropriate amount of culture soil 30 through the opening 22 of the pot 25 and then pressed down from above. Meanwhile, the tip 17 of the protrusion 15 of the seed sower 10 is immersed in a container containing adhesive water, sugar solution, etc., and inserted into the container containing the seeds 40, causing the seeds 40 to adhere to the tip 17 of the protrusion 15. Furthermore, if the tip 17 of the protrusion 15 of the seed sower 10 is made of a synthetic resin with electrostatic adsorption properties, the tip 17 of the protrusion 15 can be attached to the seed 40 depending on the shape of the seed 40 without being immersed in a container containing water, sugar solution, etc.

[0014] Next, the tip 17 of the projection 15 of the seeding tool 10 is inserted into the seedling raising tray 20 through the opening 22 of the pot 25 and overlapped. As a result of the polymerization, the seeds 40 attached to the tip 17 of the projection 15 of the seed sower 10 are sown on top of the culture soil 30 in the pot 25 of the seedling raising tray 20 as shown in the longitudinal schematic diagram of FIG. Next, the required amount of covering soil 35 is layered on top of the culture soil 30 through the holes 18 of the seed drill 10 in Figure 4, and the seeds 40 attached to the tip 17 of the protrusion 15 of the seed drill 10 are buried on top of the culture soil 30 in the pot 25 of the seedling tray 20, as shown in the longitudinal cross-sectional diagram in Figure 7. Furthermore, when the seed drill 10 is removed from the opening 22 of the seedling tray 20 in an overlapping state, as shown in the longitudinal cross-sectional view of Figure 8, the seed 40 attached to the tip 17 of the protrusion 15 of the seed drill 10 is retained in the vicinity of the culture soil 30 and the cover soil 35 due to the weight of the cover soil 35 covering the top of the seed 40 and the surrounding pressure.

[0015] Furthermore, at the stage shown in FIG. 7 or 8, water or liquid fertilizer can be irrigated from above the opening 22 of the pot 25 of the seedling tray 20.

[0016] With the sowing device of the present invention, there are no restrictions on the size or shape of the seeds, and even germinated seeds that are attached to the tip of the protrusions of the sowing device can be sown in the vicinity of the culture soil and covering soil within multiple pots in the seedling tray by overlapping the seedling tray and the sowing device and layering an appropriate amount of covering soil on top, and watering from above is also possible, making sowing work easier, more efficient, and less time-consuming.

[0017] The sowing device comprises the seedling raising tray in which a number of pots each having an opening are arranged in a regular pattern, and the seeding device in which a number of protrusions are formed at positions that coincide with the openings of the pots. The base of the protrusions is provided with a support for fixing the protrusions and holes for inserting the covering soil into the pots. By overlapping the seedling raising tray and the seeding device, the tips of the protrusions of the seeding device are inserted through the openings of the pots in the seedling raising tray, seeds are attached to the tips of the protrusions soaked in liquid, the seeds are sown on top of the culture soil filled in the pots, the top is covered with covering soil, and water is irrigated from above.
