Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grower for hydroponic cultivation.

Hydroponic cultivation uses rock wool as a seedbed and supplies nutrient solution to it to grow vegetables, flowers, etc.
Hydroponic growers are used to grow fruits, etc., and are used as containers for storing beds, nutrient solution supply pipes, etc.

[Prior Art] Conventionally, a vertically elongated container made of foamed plastic has been used as a grower for hydroponic cultivation.

This has a shape as shown in the perspective view in Figure 7, and the space on the center line of the bed is open in the form of a slit so that the seedlings can grow freely, and the upper edge of the side wall of the bed storage part has an outer side. There is a connection mechanism with a simple high step, which allows the two attached canopies to cover the grower in an arch shape.

A grower with this structure has the drawback that hydroponic cultivation cannot be carried out smoothly due to the following reasons.

First, moles, rats, etc. are damaged by eating through the bottom of the grower.

Second, in order to prevent the canopies from coming off, it takes time and effort to separately cover the upper surfaces of the left and right canopies at a position between the seedlings to prevent the canopies from coming off.

Thirdly, the nutrient solution is supplied by spraying it upward from the pipe onto the underside of the canopy, but most of the supplied nutrient solution travels down the underside of the canopy and falls only on both sides of the bed, causing the nutrient solution to drop. The liquid is not evenly distributed on the bed.

[Problems to be Solved by the Invention] The object of the invention is to provide a grower that does not have the above drawbacks and allows smooth hydroponic cultivation.

[Means for Solving the Problems] The inventor of the present invention has diligently studied the joint structure of the bottom of the grower, the canopy of the container, and the structure of the lower surface of the canopy, solved the above-mentioned drawbacks, and completed the present invention. .

A grower for hydroponic cultivation featuring:

5. The hydroponic cultivation device according to item 2 or 4, wherein the number of sections of the connecting mechanism between the canopy section and the bed storage section is three sections.

6. The hydroponic cultivation device according to item 1 or 4, wherein the foot portion is plate-shaped and extends vertically downward from the side wall of the bed storage section.

The structure and operation of the present invention will be explained in more detail with reference to drawings of embodiments.

The grower of this embodiment is entirely made of expanded polystyrene and has the structure shown in the perspective view of FIG.

Foams such as polystyrene are suitable for the inventive growth device, and foams to which powders of talc, calcium carbonate, carbon, etc. are added can also be used, if desired.

As shown in the side view of FIG. 2, the bed storage section 1 has a structure in which left and right side walls 11 and 12, each having a thickness of 3 cm, are bridged by a base plate 13 having a thickness of 3 cm in an H-shape.

There are middle stands 14 and 15 at both corners of the base plate 13, and the rock wool bed can be installed in the space surrounded by the base plate 13 and both middle stands.

The first feature of this embodiment is that 10 cm of side walls are extended from the lower edges of both side walls of the side walls 11 and 12, and these extended side walls are made into plate-shaped legs.

With this structure, when the grower of this embodiment is placed on the ground, the lower surface of the base plate 13 of the bed storage section 1 is maintained at a height of 10 cm from the ground, and the lower surface of the base plate 13 between the ground and the base plate
There is a space between 3 and 3.

Because of this space, moles and the like that come out of the ground do not bite through the base plate 13, but either advance along this space or bite through the side wall of the foot sideways, so hydroponic cultivation No damage to crops will occur.

The higher the space of the base plate 13 from the ground is, the better in order to prevent mole damage, but if it is too high, the grower will become too large, which will waste materials, make installation work inconvenient, and reduce stability.

Normally, the length should be 3 cm or more, preferably 5 cm or more, and even if it is 10 cm or more, no commensurate effect will be obtained.

In addition, there are various ways to form this space under the base plate 13, such as adding rod-shaped legs, but in a grower for hydroponic culture, the space is formed under the base plate 13 by extending the side wall downward. The structure forms a sealed space at the bottom of the bed plate 13, which is preferable because the temperature of the bed is not directly affected by changes in the outside world and there is enough strength to support the bed.

The canopy section 2 of this embodiment is divided into three sections, and the central section of the canopy section 2 has a lower edge 21 that is long on the outside and has a short step 2 on the inside, as shown in the sectional view in FIG.
2 is formed.

This step is adapted to fit into a step 16 provided in the center section of the bed storage section 1, as shown in the central sectional view of the bed storage section 1 in FIG.

Compared to the thickness of the side wall and lower edge of the canopy of 3 cm in this embodiment, the height of this step 22 is 1 cm.
The width of the step is 1.5 cm, which is half the thickness of the wall.

The higher the height of the step, the more stable the canopy will be when installed, so it is desirable, and the height is usually 5 mm or more and 2 cm.
The following degree can be selected as appropriate.

The width of the step can be appropriately selected up to about two-thirds of the width of the side wall.

The left and right sections of the canopy section 2 connected to both sides of the central section of the canopy section 2 have a width of 1.5 cm and a height of 1 cm on the inside of the lower edge, opposite to the center, as shown in Figure 1. A long step 25 is provided.

A step 17 is provided on the upper edge of the side wall of the front and rear one-third portions of the bed storage section 1 so as to fit into the left and right sections of the canopy section 2.

In this example, the central one-third portion and the front and rear three portions are
The second feature can be achieved by reversing the structure of the step with respect to the 1/2 part.

That is, if this canopy part 2 is installed so as to fit into the steps 16 and 17 on the upper edge of the bed storage part 1, the canopy part 2 will be able to stand even if there is nothing to support it other than the connection of the upper edge of the side wall of the bed storage part 1. Freestanding and fixed on the side wall.

If the steps are divided into three sections in this way, and the steps are alternately reversed and three or more connecting sections are used, the canopy will become self-supporting.
This is because the same effect as the wedge structure shown in the figure can be obtained.

In general, in a hydroponic culture grower, as shown in the cross-sectional view of FIG. A long water-shielding film 23 is laid from the bottom to the side wall, and in order to fix this water-shielding film 23, the left and right side edges of the film are extended several centimeters from the connecting part of the side wall and fixed. In this case, the sprayed water collects around the hot water pipe 25, flows in the longitudinal direction of the grower, and is collected.

However, if the connection is made in a wedge shape as shown in FIG. 5, it becomes difficult to pass the film between the connection parts and fix the film so that the edge of the film protrudes from the side wall.

In the case of the level difference of the present invention, by simply making a 5 cm cut in the water-shielding film on the line corresponding to the position where the level difference of the boundary line of each section is reversed, the film can be attached to the side wall without impairing the fixing function of the connecting part. It can be taken out and fixed smoothly.

The present invention is characterized in that it achieves the same self-supporting fixation as the wedge type by using a simple step rather than a wedge type connection mechanism.

In addition, in the case of the wedge structure shown in Figure 6, soil may get into the groove and the fitting cannot be done smoothly.
There is a drawback that the wedge may break.

As a third feature of this embodiment, as shown in the cross-sectional view of FIG. 3, projecting ribs 31, 32, and 33 are provided in the longitudinal direction of the canopy part 2.

These protruding ribs are connected to the entire hydroponic grower.

In this embodiment, in order to widely spread the nutrient solution for hydroponic cultivation, the nutrient solution is sprayed from holes made in the top surface of the tubes installed on both sides of the bed and applied to the bottom surface of the canopy.

At this time, if the ribs are present, water adhering to the canopy collects at the tips of the convex portions of the protruding ribs and drips onto the bed from there.

This action prevents the nutrient solution adhering to the lower surface of the canopy from flowing down only to both sides along the side walls, making it possible to achieve uniform dispersion.

One or more, preferably three or more protruding ribs can be provided on one canopy.

Furthermore, by providing a cut or a convex portion on the ridgeline of the protruding rib, it is possible to prevent water droplets from moving back and forth along the rib.

The shape of this protruding rib can be used without particular limitation as long as the tip is lower than the parts on both sides of the protruding rib.

The left and right canopies 2 and 3 of this embodiment have symmetrical shapes. These parts have the same shape for the left and right sides and can be used for either, making the canopy installation work easier.

The vertical length of each grower for hydroponic cultivation in this embodiment is about 90 cm, and in actual cultivation, a large number of growers are connected depending on the size of the cultivation field.

In this connection of the growing base, the canopy part and the bed storage part can be prevented from coming apart by a connecting mechanism that fits into the adjacent one.

Also, depending on the length of the growing pot or the type of crop, the connection part between the canopy and the bed storage part may be classified into 3 types.
In addition to this category, it can be divided into four or more categories.

[Effects of the invention] The hydroponic culture grower of the invention has the advantage of not being damaged by moles or rats, the ease of installing the canopy, the creation of rock wool beds, the installation of piping, etc., and the ease of cultivation. It has the advantage of being easy to use, and it greatly contributes to hydroponic cultivation.
