Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an irrigation and seeding device for a sponge-like hydroponic seedbed.

Hydroponic cultivation involves cultivating in water without using mud. For hydroponic cultivation, a sponge-like seedbed can also be used.

That is, a sponge-like seedbed soaked with water is placed inside a Styrofoam seedling box, and trefoil-like seeds are sown on the surface of the bed to cultivate the seedlings. Spongy seedbeds are suitable for hydroponic cultivation because they retain water for a long time.

By the way, even if you simply sprinkle water on the surface of a dry, spongy seedbed, the air bubbles inside the seedbed contain air, so the water will only wet the surface of the seedbed, and much of the water will be repelled. However, it does not penetrate inside the seedbed easily.

Therefore, conventionally, the sponge-like seedbed was placed in a container such as a bucket and squeezed by hand to suck out water and keep it moist.

Therefore, it took a very long time.

Also, it is not possible to squeeze out a large spongy seedbed evenly at once, so even if you squeeze the seedbed underwater,
It was difficult to force out the air completely, and on average it was impossible to make it water-soaked.

Therefore, the present invention provides a transfer table for transferring a Styrofoam seedling box fitted with a sponge-like seedbed.
A pressure roller that presses the sponge-like seedbed from above is provided, an auxiliary roller is provided behind the pressure roller, an irrigation nozzle that can irrigate the sponge-like seedbed is provided near the pressure roller, and seeds are sown at a position in front of the sponge-like seedbed in the transport direction. An irrigation seeding device for a sponge-like hydroponic seedbed equipped with a device, and a transfer table for transferring a styrofoam seedling box fitted with a sponge-like seedbed are provided with a pressure roller that presses the sponge-like seedbed from above, and the pressure roller In an irrigation and seeding device for a sponge-like hydroponic seedbed, an auxiliary roller is provided at the rear of the pressure roller, an irrigation nozzle that can irrigate the sponge-like seedbed is provided in a position near the pressure roller, and a seeding device is provided in a forward position in the transport direction. A plurality of pressure rollers are provided in the direction of movement, and are configured as an irrigation and seeding device for a sponge-like hydroponic seedbed.

An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a sponge-like seedbed. The seedbed 1 has numerous open cells.

The seedbed 1 is formed into a pine-like shape with a thickness of approximately 3 to 4 cm, and the entire seedbed 1 is provided with perforation-like cuts 2 at predetermined intervals vertically and horizontally. The cut 2 is for dividing the seedbed 1 into individual plants.

The size of the seedbed 1 is matched to the internal volume of the seedling box 3 that houses the seedbed 1, and FIG. 2 shows the size of the seedbed 1.
This figure shows the state in which the seedlings are housed in the seedling raising box 3.

The seedling raising box 3 is formed at a depth such that the upper surface of the seedling bed 1 and the upper surface of its frame are approximately at the same height.
is made of a material that floats on water, such as Styrofoam.

In FIG. 3, reference numeral 4 denotes a transfer table for the seedling growing box 3, which is formed long in the direction of transferring the seedling growing box 3, and is installed on the floor by supporting legs 5 provided at desired positions.

A desired number of guide rolls 6 are provided on the transfer table 4 at predetermined intervals, and the guide rolls 6 are rotated at a constant speed by being rotated by a conveyor drive motor 7 provided on the transfer table 4 and a chain 8.

Seedling raising box 3 placed on the upper surface of the guide roll 6
is transferred toward the take-out side 9 of the transfer table 4.

The seedling raising box 3 is placed at the starting end 10 of the transfer table 4.
An offset prevention plate 11 is provided to allow the paper to move straight in the conveyance direction (back and forth direction).

An auxiliary roller 12 is provided in front of the deviation prevention plate 11.

The auxiliary roller 12 is inserted through the horizontal shaft 13. A plurality of horizontal axes 13 are provided at predetermined intervals.
A sprocket 15 is fixed to the protrusion of the horizontal shaft 13, and a chain 14 is wound around it. Said auxiliary roller 1
2 are attached to the horizontal shaft 13 with a width spaced apart so as to abut on the left and right frames of the seedling raising box 3.

The auxiliary roller 12 is used to hold down the seedling growing box so that it does not fall over.

Therefore, the auxiliary roller 12 is the guide roller 6
It is effective to place it directly above the (Figure 4).

A first pressure roller 16 is provided in front of the auxiliary roller 12.

The pressure roller 16 is a roller that presses the sponge-like seedling bed 1 in the seedling raising box 3 from above to force out air, and is formed in the shape of an uneven wave shape along the front and back direction of the transfer table 4 on its surface. Sometimes.

The pressure roller 16 is formed to have a length that matches the inner width of the seedling box 3 in order to press the seedling bed 1, and has a shaft 17 protruding from both ends in the left-right direction of the transfer table 4 to support the shaft 17. It is rotatably attached to the plate 18.

A sprocket 19 is fixed to the part of the shaft 17 that protrudes from the support plate 18.
sprocket 2 attached to the shaft of guide roll 6.
0 and the chain 21 is passed around. Support plate 1
Attach the support fitting 22 to the tip of the support fitting 2.
A vertical screw hole 23 is formed in screw hole 2.
3, the upper end of the spring 25 is engaged with the lower end of the vertical screw 24, the lower end of the spring 25 is engaged with the upper surface of the transfer table 4, and the spring 25 is attached to the support plate 18. The attached pressure roller 16 is pressed against the seedbed 1.

Another screw hole 26 is formed in a part of the support fitting 22, and an adjustment rod 27 is screwed into the screw hole 26.
A rubber 28 is attached to the lower end of the adjustment rod 27.
The rubber 28 comes into contact with the transfer table 4 and stops the downward movement of the support plate 18. 29 is a loosening prevention spring, and 30 is a knob.

Thus, the irrigation nozzle 31 is provided near the pressure roller 16.

The irrigation nozzle 31 may be provided near the front of the pressure roller 16 or above the pressure roller 16.

A second pressing roller 32 formed in exactly the same manner as the pressing roller 16 is provided in front of the pressing roller 16. The second pressure roller 32 is the pressure roller 16
It has the same structure as , but just by pressing the seedbed 1,
The irrigation nozzle 31 may not be provided.

That is, the pressure roller 16 is used to press the seedbed 1 that has not yet absorbed water, and to irrigate the seedbed 1 when it swells to return to its original shape due to its elastic restoring force. 32 is installed for the purpose of pressing the seedbed 1 many times since it is not possible to irrigate sufficiently just once, and is provided to press the seedbed 1 again and completely push out the air in the bubbles in the seedbed 1.

Therefore, although only one second pressure roller 32 is provided in the embodiment diagram, a plurality of second pressure rollers 32 may be provided.

Next, a seeding device 33 is provided in front of it. The seeding device 33 is formed by a hopper 34 and a feed roll 35. 36 is the seeds of mitsuba and japonica sown in nursery bed 1.

In addition, 37 is an auxiliary irrigation device, 38 is a pump, 3
9 is a water receptacle.

Next, we will discuss the effect.

The seedling box 3 is placed on the guide roll 6 on the supply side 10 of the transfer table 4, and when the conveyor drive motor 7 is energized, the guide roll 6 rotates via the chain 8.
The seedling growing box 3 placed on the upper surface of the guide roll 6 is corrected by the offset prevention plate 11 and is conveyed straight toward the take-out side 9.

The tip of the seedling growing box 3 thus transported moves forward while being sandwiched between the auxiliary roller 12 and the guide roll 6, and comes into contact with the pressing roller 16.

The pressing roller 16 overcomes the frame of the seedling raising box 3 and presses the seedling bed 1 sequentially from the tip with the elasticity of the spring 25.

At this time, the seedling raising box 3 is strongly pressed by the pressure roller 16, but since its rear part is held between the auxiliary roller 12 and the guide roll 6, the rear end of the seedling raising box 3 does not float up and is properly placed in the seedling bed. 1 is pressed by a pressure roller 16, and the air in the seedbed 1 is pressed.

Since the area near the pressure roller 16 is irrigated with water from the irrigation nozzle 31 to flood the seedbed 1 with water, the pressed seedbed 1 absorbs water when it swells to return to its original shape due to its elastic restoring force. That's what I do.

That is, when the seedbed 1 is pressed by the pressure roller 16, the air bubbles located directly under the pressure roller 16 release the air inside the bubbles due to the pressure.
Since the spongy seedbed 1 has a high elastic restoring force, when the pressure roller 16 stops pressing the seedling bed 1, the spongy seedling bed 1 tries to return to its original shape due to the elastic restoring force and expands, and at this time, air bubbles are Instead, it sucks in the water around the bubbles.

In this way, the air in the bubbles of the spongy seedbed is forced out and water is drawn into the bubbles instead, and this action is prevented by the second pressure roller 3.
Repeat again with step 2 to aspirate completely.

Then, seeds 36 of Japanese mitsuba, japonica, and the like are sown in the watered seedbed 1 using a sowing device 33.

The sown seeds 36 will soon germinate, so
When the seedling raising boxes 3 are stacked and placed, the seedling raising boxes 3 are formed at a depth such that the upper surface of the seedling bed 1 and the upper surface of the frame are the same height, so the seeds are placed in the seedling bed 1. Roots inward. After that, when they are grown by feeding them with liquid fertilizer, etc., they grow as shown in Fig. 6.

The seedling growing box 3 is made of polystyrene foam or the like and is made to float on water, so in a plastic greenhouse equipped with an aquarium, it can be placed floating on the water surface, or it can be placed on a shelf installed inside the plastic greenhouse to carry out the growing process. You can also.

After growing and when shipping, the seedbed 1 is made with cuts 2 of a desired depth at predetermined intervals in the vertical and horizontal directions from the height direction, so that the grown mitsuba and chinensis can be placed in the seedbed by dividing the seedbed 1. It can be sold in a fresh state with 1 still attached.

In general, even if you simply sprinkle water on the surface of a spongy seedbed, the air bubbles inside the seedbed contain air, so the water only wets the surface of the seedbed, but much of the water is repelled, making it difficult for the seedbed to grow. Conventionally, sponge-like seedbeds were placed in a container such as a bucket and wrung out by hand to absorb the water and keep it moist.
Therefore, it took a lot of time. In addition, it is not possible to squeeze out a large spore-like seedbed evenly at once, so even if you squeeze the seedbed underwater, it is difficult to completely push out the air, making it impossible to supply water evenly. .

Therefore, the present invention provides a transfer table for transferring a Styrofoam seedling box fitted with a sponge-like seedbed.
A pressure roller that presses the sponge-like seedbed from above is provided, an auxiliary roller is provided behind the pressure roller, an irrigation nozzle that can irrigate the sponge-like seedbed is provided near the pressure roller, and seeds are sown at a position in front of the sponge-like seedbed in the transport direction. An irrigation seeding device for a sponge-like hydroponic seedbed equipped with a device, and a transfer table for transferring a styrofoam seedling box fitted with a sponge-like seedbed are provided with a pressure roller that presses the sponge-like seedbed from above, and the pressure roller In an irrigation and seeding device for a sponge-like hydroponic seedbed, an auxiliary roller is provided at the rear of the pressure roller, an irrigation nozzle that can irrigate the sponge-like seedbed is provided in a position near the pressure roller, and a seeding device is provided in a forward position in the transport direction. Since the pressure roller is characterized by the configuration of a spongy hydroponic seedbed irrigation and seeding device with multiple locations in the moving direction, (a) it is possible to continuously irrigate the seedbeds laid out in the seedling box.

(b) A large amount of seedlings can be irrigated in a short period of time.

C. Water can be supplied to the nursery on average.

It has this effect.
