Hydroponic cultivation trays {TRAY FOR HYDROPONICS}

The present invention relates to a hydroponic cultivation crop tray, and more particularly, a hydroponic cultivation crop tray capable of preventing water stagnation that inhibits the growth of crops by improving the flow of water (or nutrient solution) flowing inside the tray. It is about.

Hydroponic cultivation is one of the plant cultivation methods that allows the cultivation of the hydroponic plants floating on the surface of the water to be submerged.They can be mass-produced, and cultivated in the spotlight due to the advantages of pollution-free cultivation and freshness. Is one of.

Such hydroponic cultivation has recently been rapidly spreading because it can meet the current consumption pattern of reducing cropland and fresh vegetables for four seasons according to industrial development.

Hydroponic cultivation may include all kinds of edible vegetables (eg, sprouts), as well as grass feed for raising pigs and beef cattle. In particular, in the case of grass feed, it is almost dependent on income due to the decrease of the cultivation area and the decrease of the grassland composition area, and the introduction of hydroponic cultivation is actively considered as a solution to such a problem.

In general hydroponic cultivation, a container, that is, a culture plant contained in a tray (tray) is grown by receiving appropriately water or nutrient solution supplied from the outside. An important requirement for such hydroponic cultivation is to ensure a smooth flow of water (or nutrient solution).

1 is a view schematically showing a conventional hydroponic crop tray. As shown, the conventional hydroponic crop tray 1 is fixedly installed in the form of a shelf on the vertical rack 31 and the lattice rack structure 30 formed by the horizontal member 33. The trays 12 and 12 'have a container shape with an open top so as to stably receive seeds S of crops scattered through the bottom surface.

The water supply part 22 which supplies water (or nutrient solution) w is formed in the front end part of the tray parts 12 and 12 ', and the growth of a crop is provided toward the end part of the tray parts 12 and 12'. It is provided with a water outlet 24 which is used to discharge the remaining water (or nutrient solution).

 Here, the conventional hydroponic crop tray 1 is tilted downward at a predetermined angle so that the supplied water (or nutrient solution) w can flow smoothly from the leading end of the tray 12, 12 'to the end direction. In the form of a photograph.

2 is a view showing the water flow of the conventional hydroponic crop tray.

In the figure, the upper portion is the tip portion 12a of the tray portion 12 provided with the water supply portion 22, and the lower portion is the end portion 12b of the tray portion 12 provided with the water outlet 24.

However, in the case of the conventional hydroponic crop tray, the water supply unit 22 has a single discharge structure, and it is difficult to uniformly supply the sprayed water with respect to the width direction of the tray unit 12. Accordingly, in order to make the growth conditions of the crops as uniform as possible, the arrangement of the crops accommodated on the tip 12a side of the tray 12 is in the form of a triangular (or fan-shaped) arrangement P1. However, in this case, since the cultivation area is limited within the narrow tray portion 12, it has a disadvantage in terms of space utilization.

Furthermore, in the case of conventional hydroponic crop trays, there is a problem in that water clogging (or water clogging) occurs frequently at the rear end portion 12b of the tray portion 12. This phenomenon is caused by the deterioration of drainage flow as the roots of growing crops grow, and as a result, the roots of the growing crops decay, which adversely affects the harvestability of the crops.

As a solution to this problem, a method of increasing the inclined angle of the tray part 12 to further induce drainage flow may be considered. However, if the drainage flow becomes excessively fast, absorption of water (or nutrient solution) necessary for the growth of the crop may not be satisfactorily achieved, which may adversely affect the growth of the crop.

Therefore, in hydroponic cultivation, the flow of water (or nutrient solution) is improved to improve the growth conditions of the crop, while the flow of water (or nutrient solution) on the drain side is relatively fast to prevent the root rot of the crop due to water retention. Find ways to do it.

It is an object of the present invention, the hydroponic cultivation crops that can structurally prevent the problem that the roots of the crops grow as the growth period elapses, so that the water clogging phenomenon appears on the drainage side (that is, the end of the tray) of the hydroponic cultivation crop tray In providing a tray.

Another object of the present invention, by spraying the water (or nutrient solution) evenly in the width direction with respect to the seeds of the crop housed on the bottom surface of the crop tray for a hydroponic cultivation crop tray that can be grown in a uniform growth conditions In providing.

Still another object of the present invention is to provide a hydroponic cultivation crop tray capable of easily correcting a width difference in a width direction of a crop tray so that the bottom surface of the tray can be horizontal to improve crop growth conditions.

Problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned herein will be clearly understood by those skilled in the art from the following description.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. However, the present invention is not limited by the embodiments disclosed below but may be embodied in various different forms. The embodiments to be described herein are provided so that the disclosure of the present invention is complete and that those skilled in the art will fully understand the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, the present invention will be described with respect to a preferred embodiment of the hydroponic cultivation crop tray.

3 is a view schematically showing the hydroponic cultivation crop tray of the present invention. 3 is a view showing only the main features in detail in order to conceptually and clearly understand the configuration relationship of the present invention.

Referring to FIG. 3, the hydroponic cultivation crop tray 100 illustrated includes a tray part 110, a width height adjusting part 130 for adjusting the height of the tray part in a horizontal direction, and water for supplying water into the tray part. It consists of a configuration including a supply unit (120).

First, the tray unit 110 will be described.

The tray unit 110 is a rectangular container member whose top is open to stably accommodate the seeds S of crops scattered to the bottom surface.

In particular, the tray unit 110 of the present invention is fixedly installed in the lattice-shaped rack structure 200 formed of the vertical member 210 and the horizontal member 220, two of the rack structure 200 to form a set Is placed within the lattice space.

One end portion of the tray 110 in which the water (or nutrient solution) is supplied is the front end portion, and the other side from which the remaining amount is discharged after the supplied water (or nutrient solution) is absorbed by the growing crop. The site is referred to as the terminus.

The illustrated tray portion 110 has a rectangular cross section formed with a longer left and right width length than an upper and lower height, and has a rectangular container shape formed long in the longitudinal direction from the leading end portion to the rear end portion. However, the present invention is not necessarily limited to this specific shape. That is, the tray unit 110 according to the present invention can be any type as long as it can stably receive the seed of the crop into the inner space, and can maintain the water (or nutrient solution) supply until the growth of the crop is completed. The shape may be changed little by little.

The tray unit 110 is seated on the upper side of the horizontal member 220 of the lattice rack structure 200, and then various fastening means (for example, bolts, nuts) or various methods of bonding (for example, bonding, Position can be fixed by welding).

And the tray part 110 of the present invention is formed to be inclined downward at a predetermined angle (ie, the first angle) in the longitudinal direction from the tip portion from which the water supply starts.

Here, as a preferable range of the 1st angle a1, 1-2 degrees can be presented.

The length section of the tray part 110 formed to be inclined downward at the first angle a1 is called the first inclination section 110a.

That is, the first inclination section 110a refers to a section portion formed to be inclined at a first angle a1 from the distal end of the tray section 110 to a predetermined length, and is different from the second inclination section 110b to be described later. Based on different inclination angles.

In addition, the tray part 110 of the present invention is predetermined downward from the position where the first inclined section 110a ends, to the end of the tray section 110, further downward than the first inclined section 110a. It is formed to be inclined downward at an angle (ie, a second angle).

Here, 2.4 to 3 degrees can be presented as a preferable range of the second angle a2.

In addition, another length section of the tray 110 formed to be inclined downward at the second angle a2 is called a second slope section 110b.

That is, the second slope section 110b is a section portion extending from the above-described first slope section 110a in the direction of the end portion of the tray section 110, in order to prevent the trapping phenomenon, which was a conventional problem. The inclined gradient of the end of the tray 110 is made larger.

If the second angle a2 of the second inclination section 110b is less than 2.4 °, the effect of preventing the water trapping of the target end portion is insignificant, whereas the second angle a2 exceeds 3 °. As the seed of the crop flows toward the water outlet 126 to be unloaded, a problem of poor drainage may result.

Here, the first inclined section 110a and the second inclined section 110b are not independent members that are separated from each other and are assembled or coupled to each other, but are continuous bodies having a series of configurations, and inclined angles a1 and a2. ) Is divided into length sections.

In particular, the present invention is to solve the problem of the water trap of the drainage side (that is, the end of the tray portion) in the conventional hydroponic crop tray (see Figs. 1 and 2), the optimum that can be improved The angular range of was derived through several experiments.

Such an angular range means an angular range in which the flow of water (or nutrient solution) is too fast, which does not adversely affect the growth environment of the crop, and at the same time prevents water freezing on the drain side.

In the following [Table 1], the comparative example is not divided into the first inclined section and the second inclined section, the entire tray portion is inclined at 2 degrees in the longitudinal direction.

On the contrary, in the first embodiment, the angle a1 of the first inclination section is 2 °, but the additional inclination section is relatively relative to the end of the tray part 110 with the angle a2 of the second inclination section 2.4. Placed.

And in the case of Example 2, the angle a2 of the second slope section is 2.6 °, and in the case of Example 3, the angle a2 of the second slope section is 2.8 ° relative to the end of the tray 110. There was an additional slope section.

In addition, in the fourth embodiment, the angle a2 of the second inclined section is 3.0 °, and in the fifth embodiment, the angle a2 of the second incline section is 3.2 °, There is a relative additional slope section.

The results of this experiment can be confirmed through the following [Table 1].

division 1st slope section Second Slope Section Tip water flow Terminal bite prevention Comparative Example 1 2 ° ○ x Example 1 2 ° 2.4 ° ○ ◎ Example 2 2 ° 2.6 ° ○ ◎ Example 3 2 ° 2.8 ° ○ ◎ Example 4 2 ° 3.0 ° ○ ◎ Example 5 2 ° 3.2 ° ○ △

◎: Very good ○: Good △: Normal x: Poor

Referring to the result of [Table 1] above, the end portion when the additional inclined section is provided with a second inclined section relatively compared to when maintaining a constant inclination of 2 ° with respect to the entire length of the tray section 110 It was found that the prevention of bite appeared effectively.

Particularly, in Examples 1, 2, 3, and 4, the angle range of the second inclined section 110b is within 2.4 to 3 °, indicating that the end portion of the tray 110 has a good anti-damp effect. Could. On the contrary, in Example 5, the angle of the second inclined section 110b was set to 3.2 °. In this case, the effect of preventing the end bite was improved compared to the comparative example, but the seed of the crop was discharged from the water outlet 126. Inflow into the water) resulted in a poor drainage flow.

Therefore, through the experimental results of the above [Table 1], the preferred angle range of the second slope section in the present invention is presented as 2.4 ~ 3 °.

Next, the water supply unit 120 will be described.

The water supply unit 120 serves to supply water (or nutrient solution) w into the tray unit 110 described above. In particular, the water supply unit 120 may include an internal flow path formed along the bottom surface of the tray unit 110. Means of supplying water (or nutrient solution) towards the 'channel'.

The water supply unit 120 is piped to the front end portion, is formed so as to spray water (or nutrient solution) evenly to the seed of the crop accommodated in the tray 110.

The water supply unit 120 according to the present invention has a structure of injecting a fixed amount in the longitudinal direction of the pipe after introducing water (or nutrient solution) along the pipe of the long form, out of the conventional single outlet.

Specifically, the water supply unit 120 according to the present invention as a detailed configuration, the supply pipe 122 is arranged in a straight form, and the water injection hole 124 formed with a plurality of through-holes spaced in the longitudinal direction of the supply pipe do.

One side of the supply pipe 122 is connected to the main pipe (L1). And the water is supplied from the external water storage tank (not shown) through the main pipe (L1).

The water injection hole 124 refers to a plurality of through holes formed at regular intervals along the longitudinal direction of the supply pipe 122.

Here, the diameter of each of the water injection port 124 is preferably the same, and water (or nutrient solution) sprayed through it may be evenly supplied toward the seed of the crop accommodated in the tray 110.

However, the number and diameter of the water injection hole 124 need not necessarily be limited to the specific shape shown, and is carried out little by little depending on various conditions (for example, the width of the tray portion, the water supply flow rate, the seed arrangement form of the crop, etc.) can be changed.

Figure 4 is a view showing the side installation structure of the hydroponic cultivation crop tray according to an embodiment of the present invention.

With reference to Figure 4, it will be described in detail with respect to the width height adjustment unit 130 in the present hydroponic cultivation crop tray.

The width height adjusting unit 130 is a means for adjusting the height in the left and right width directions with respect to each of the tray units 110 installed in the rack structure 200.

That is, the grid-shaped rack structure 200 formed of the vertical member 210 and the horizontal member 220, as well as the plurality of trays 110 installed therethrough, are aligned horizontally in the horizontal direction in the initial installation stage. This is done.

However, as time elapses, the bottom surface of the tray 110 may be displaced from the initially set horizontal alignment state, and may cause a problem of being slightly inclined to one side.

If the height of the left and right width directions of the tray 110 is incorrect, seed storage of crops accommodated inside the tray 110 may be difficult to be stably performed, and in addition, the flow of water (or nutrient solution) may not be good. May affect

In the present invention, the width height adjusting unit 130 is a component devised to solve such problems, and serves to correct the structural error of the width in the horizontal direction of the tray 110.

In addition, as the width height adjusting unit 130 according to the present invention, a bolt member fastened by penetrating upward through the horizontal member 220 on the rack structure 200 may be used.

The end (ie, the upper end) of the bolt member penetrates upward through the horizontal member 220, and then protrudes upwardly to face the bottom surface of the tray 110. At this time, by adjusting the screw entry distance of the bolt member, that is, the lead (lead) it is possible to adjust the height of each end of the tray portion 110.

These bolt members are provided at both ends of the tray unit 110. When the horizontal alignment of the tray unit 110 is misaligned, the bolt members provided at both ends of the left and right width directions are rotated one by one to make the tray unit 110 horizontally. You can correct the fit.

Referring to FIG. 5, the configuration of the width height adjusting units 130a and 130b using the bolt member may be confirmed.

However, in such an embodiment, after the worker puts his hand into the lower portion of the tray 110, he has to take the trouble of rotating the corresponding bolt members 130a and 130b in the forward / reverse direction using a tool such as a screwdriver. do. Another embodiment is disclosed in FIG. 6 as a solution for reducing such inconvenience.

Referring to FIG. 6, in order to eliminate operational inconvenience in the embodiment of FIG. 5, a detailed configuration using a rack pinion gear is provided as a detailed configuration of the width height adjusting unit.

As shown in FIG. 6, the detailed configuration of the width height adjusting unit includes an operation handle 142 having a handle 141, a rack pinion gear including a pinion 144 and a rack 146, and a connection block ( 148).

The manipulation handle 142 includes a handle 141 exposed to the outside of the rack structure, through which the user can easily grip and rotate the handle 141.

The rack pinion gear is one of the well-known and conventionally known gear devices, and is configured to move the rack 146 in a linear direction by interlocking relationship with each other according to the rotation of the pinion 144.

That is, when the manipulation handle 142 is driven to rotate by the user, the pinion 144 connected to the rotation axis of the manipulation handle 142 is rotated. And the rack 146 is to drive up and down in the vertical direction.

A connection block 148 fixed to the bottom surface of the tray 110 may be disposed at the end of the rack pinion gear. Both ends of each of the tray unit 110 supported by the connection block 18 is elevated in the vertical direction, whereby the height of each of both ends of the tray unit 110 can be easily adjusted.

Referring back to Figure 4 will be described with respect to the angle adjustment unit 150, which is one of the detailed configuration of the hydroponic cultivation crop tray of the present invention.

The angle adjusting unit 150 is provided between the first slope section 110a and the second slope section 110b in the tray 110 to vary the range of the second angle (a2 in FIG. 3). It is a means of control in response to conditions (eg crop change).

As shown, the angle adjuster 150 according to the present invention, the elastic piece 152, and includes a detailed configuration of the arc bracket 154.

The elastic piece 152 partially cuts the sidewall between the first inclined section 110a and the second inclined section 110b on the tray part 110 and is inserted into the cut V groove. Speaks of absence.

Here, the tray section 110 formed by dividing the length section into the first inclined section 110a and the second inclined section 110b is not a separately divided body but a series of bodies as briefly mentioned above.

In other words, in order to set a larger angle of the second inclined section 110b on the tray part 110, a bottom surface of the tray part 110 is applied by applying a load P to the end of the tray part 110. Bend properly. In addition, the load P should be preceded by the work to cut the boundary sidewalls of the first slope section 110a and the second slope section 110b.

That is, when the sidewall of the tray section 110 is cut and then a load P is applied to the end portion, the bottom surface of the tray section 110 is bent downward, and at the same time, the V-shaped groove is formed at the cut sidewall portion. Is formed.

However, since the tray unit 110 must form a channel through which water (or nutrient solution) flows along the bottom surface, it is important that water (or nutrient solution) does not leak through the side wall.

To this end, an elastic piece 152 is required to fill the V-shaped groove to be formed in the cut side wall portion.

That is, it is preferable that the extension portions are formed at both sides such that the size of the elastic piece 152 is larger than the size of the V-shaped groove to be formed in the cut side wall portion, to achieve a leakage blocking effect. And the manner in which the elastic piece 152 is inserted into the V-shaped groove, may be made in various forms through the adhesive or mechanical fastening means (for example, pins).

On the other hand, the arc bracket 154, on the other hand, is a means for fixing the angular deformation between the first inclined section 110a and the second inclined section 110b interposed therein the elastic piece 152. The arc bracket 154 serves to fix the angular deformation between the first inclined section 110a and the second inclined section 110b, through which the fastening bolts 156 are inserted at both ends. The ball is provided.

By using the angle adjusting unit 150, the end angle of the tray 110 can be set slightly differently in response to various growth conditions (for example, seed shape and size of crops) for each crop. There is an excellent advantage in terms of harvestability and product utilization.

Figure 7 is a plan view showing a use form of the hydroponic cultivation crop tray according to an embodiment of the present invention. Referring to Figure 7, it will be briefly described the effect of the present invention hydroponic crop tray.

In particular, the water supply unit 120 of the present invention has a structure in which a predetermined amount of water (or nutrient solution) is evenly sprayed and supplied through the width direction of the tray unit 110.

Therefore, as in the conventional crop tray, the arrangement of the crops accommodated on the tip side of the tray section 12 need not be triangular or scalloped (P1 in Fig. 2).

That is, in the case of the present invention, the seed (S) of the crop can be accommodated in the form of a linear arrangement (P2) excellent in terms of space utilization.

In addition, since the flow of water (or nutrient solution) is slightly faster in the second inclination section 110b after passing through the first inclination section 110a (ie, f1 <f2), the second inclination section 110b, in particular, the tray. Stagnation of water flow at the end of the unit 110 may be prevented.

As a result, as in the conventional crop tray, it is possible to prevent the problem that the water clogging occurs, so that the roots of the crops growing in the corresponding area is rotten.

As described above, according to the hydroponic cultivation crop tray of the present invention, in the hydroponic cultivation crop tray, it is possible to prevent the appearance of water soak on the drainage side (ie, the end of the tray) due to various causes such as root growth of crops. can do. This effect can be achieved by providing additional ramp sections in the end section of the tray.

For this reason, according to the present invention, it is possible to effectively prevent the problem of the roots of the growing crop rotting, it is possible to increase the yield of the crop.

In addition, in the case of the present invention, water (or nutrient solution) for the whole section in the width direction of the tray can be supplied to the seed of the crop accommodated in the crop tray, thereby improving the growth conditions of the crop uniformly.
