Description

Multilayer Aerophonic Cultivation Equipment {MULTISTAGE AEROPONICS CULTIVATING EQUIPMENT}

The present invention relates to an apparatus for cultivating plants, and more particularly, to a cultivation apparatus with improved space utilization in cultivating plants in an aerophonic manner.

In general, a method of growing plants in a nutrient solution made of water and water-soluble nutrients without using soil is called hydroponic cultivation. Hydroponic cultivation, which was used only for special purposes in the past, is spreading to various plants as interest in eco-friendly pesticide-free cultivation has recently increased.

Hydroponics is a method of growing plants in a state where the roots of the plants are directly immersed in water, not soil. Since the number of plants that can be grown is limited to hydroponically grown plants that can be grown in a state where the roots are directly submerged in water, the number of plants that can be grown is very large. There are few downsides.

One of the reasons hydroponic cultivation plants are limited is that, unlike when planted in soil, the roots are continuously immersed in nutrient solution, so the problem of insufficient oxygen supply to the roots has been pointed out, and the problem of oxygen supply has been pointed out as a disadvantage of hydroponics itself. It is becoming.

Accordingly, an aeroponics cultivation method has been proposed in which plants are grown by spraying a nutrient solution containing nutrients to the roots in a state in which the roots are exposed to the air. In that it is directly sprayed on the roots exposed to the atmosphere, it is clearly different from spraying and providing water or nutrient solution in the conventional hydroponic cultivation or cultivation process using soil. Since this aerophonic method sprays only the necessary amount of nutrient solution, sufficient oxygen is supplied to the roots, so the cultivation efficiency is excellent and the amount of nutrient solution used is relatively small. However, since a device for spraying a nutrient solution is installed, the initial cost is higher than that of a hydroponic cultivation device that simply uses a nutrient solution tank.

On the other hand, since soil is unnecessary in the case of hydroponic cultivation, a hydroponic cultivation device called a so-called "plant factory" is proposed by installing a plurality of hydroponic cultivation plates in multiple layers so that the roots touch the culture medium to grow plants. The form of installing a cultivation plate in a plurality of layers is also applied to the aerophonic cultivation method, but there is a problem in that space utilization is lowered and the initial installation cost is higher because nutrient solution injection equipment is installed on each floor.

1 is a view for explaining the structure of an aerophonic cultivation device according to an embodiment of the present invention, and FIG. 2 is a view for explaining how a cultivation plate is installed in a chain of the aerophonic cultivation device according to an embodiment of the present invention. 3 is a cross-sectional view illustrating a state in which a light blocking plate is installed on a cultivation plate used in an aerophonic cultivation apparatus according to an embodiment of the present invention.

The aerophonic cultivation device of this embodiment includes a plurality of cultivation plates 100, a transfer unit 200, and a spray unit 300.

The cultivation board 100 is a member on which plants to be cultivated are planted, and is a plate-like member in which the roots of plants can be exposed to the atmosphere. A plurality of spaces are formed so that a plurality of plants can be planted, and may be composed of one plate-like member, or a plurality of plate-like members may be fixed to a predetermined frame. The structure of the cultivation plate 100 is not particularly limited, but in this embodiment, a long length and narrow width was applied to increase space utilization.

In addition, in this embodiment, the cultivation board 100 moves in vertical and horizontal directions while being mounted on the conveying unit 200, and the roots of the plant are configured to face downward even when the moving direction is changed. The rear panel 100 of this embodiment is mounted on the transfer unit 200 through a fastening member 110, and the fastening member 110 is a coupling unit 111 having a coupling hole fastened to the coupling pin 222 of the transport unit 200. ) and a connecting portion 112 extending to the lower portion of the coupling portion 111. The rearing plate 100 of the present embodiment is moved due to the weight of the rearing plate 100 by being hung on the coupling pins 222 of the transfer unit 200 through the coupling holes 111 of the fastening member 110. Even in the process of changing direction, the plant's roots point downward.

The fastening member 110 may be integrally formed with the rearing board 100, or it is formed below the connection part 112 and the rearing board 100 is installed in a frame or mounting space separated from the rearing board 100. can also be applied. When configured as a separable type, the fastening member 110 can install and remove only the rear panel 100 while being fixed to the chain 220, thereby facilitating work.

The transfer unit 200 may increase the efficiency of the cultivation space by moving the cultivation plates 100 in the vertical direction. At this time, the injector 310 is disposed under the transfer unit 200 so that the injector 310 sprays the nutrient solution to the root of the cultivation board 100 located at the bottom among the multiple layers, and the nutrient solution is sprayed at the position where the nutrient solution is sprayed. Nutrient solution can be supplied to a plurality of cultivation plates 100 through one injector 310 by sequentially positioning the cultivation plates. After all, since fewer injectors 310 are installed than the number of the multi-layered cultivation plate 100 or the number of arranged layers, compared to the conventional multi-layered aerophonic cultivation apparatus in which injectors are installed for each layer. It can greatly reduce the installation space and reduce the installation cost.

The transfer unit 200 of this embodiment is composed of a sprocket 210 and a chain 220. As described above, the chain 220 has coupling pins 222 for installing the redistribution plate 100, and can move the installed redistribution plate 100 in the vertical direction while moving by the power of the active sprocket to which the actuator is connected. there is. In addition, when the sprockets 210 are staggered with the lower sprocket 211 and the upper sprocket 212 at different heights and one chain 220 is installed, the rear plate 100 installed on the chain 220 and moving together It moves not only vertically but also horizontally. At this time, since the moving plate 100 installed on the chain 220 is located at the lowest position when passing the lower sprocket 211, in this embodiment, the spraying unit 300 adjusts to the number and location of the lower sprocket 211. of the injector 310 was positioned. In addition, in the structure in which the rearing plate 100 moves in the horizontal direction, workers who install and remove the rearing panel can work in one place without moving, and the work space is located on one side of the device. Since this arrangement does not require the operator to move inward, more rearrangement plates 100 can be installed by narrowing the installation interval of the sprocket 210 .

It is preferable that the direction in which the chain 220 and the rear plate 100 move, that is, the rotational direction of the sprocket 210 can proceed in both directions rather than in only one direction. And in this embodiment, by installing the circulation sprocket 213 at a higher position than the lower sprocket 211 and the upper sprocket 212 and installing a chain in the form of a closed curve, when the chain 220 continues to move in one direction, it returns to the original position. It was configured to have a returning circulation structure.

In addition, an actuator is connected to one of the circulation sprockets 213 to be applied as an active sprocket 213a, and the remaining sprockets are all passive sprockets, but are not limited thereto. The actuator connected to the active sprocket 213a may use a servo motor. In particular, when a stepping motor is applied, one rotation plate rotates step by step at a predetermined angle so that the lower sprocket 211 is installed at the lowest position for each operation. this is possible In addition, it may be applied with a position sensor for detecting the position of the cultivation plate while using a servo motor or a general motor, or may use a micro switch.

Also, according to the arrangement positions of the upper sprocket 212 and the lower sprocket 211, the chain 220 may be vertically disposed or may be diagonally disposed as shown. As shown, there is an advantage of increasing space utilization when arranged vertically, and when arranged diagonally, there is an advantage of widening the spacing between plants, so it can be selectively applied as needed.

The transfer unit 200 through the sprocket 210 and the chain 220 described above consists of a pair disposed facing each other, and the coupling pins 222 protruding in the direction facing each other from the chains 220 on both sides. Coupling holes 111 formed at both ends of the rear panel 100 are coupled to ).

The distance between the facing sprocket 210 and the chain 220 is matched to the size of the rear panel 100 or the size of the installation space. In the case of matching the size of the installation space, the size of the rear panel 100 is also customized to adjust accordingly. Conversely, if the size of the redistribution plate 100 is standardized, it is difficult to accurately fit the installation space, but it is advantageous for mass production, and if the size of the installation space is standardized, customized construction is possible even if the size of the redistribution plate 100 is standardized. For example, if the size of the cultivation plate 100 is standardized in accordance with a container box for transportation of which the standard has been determined to some extent, it can be customized to the container box while mass production is possible. In the case of standardization according to the size of the transport container box, not only the size of the cultivation plate but also the installation position of the sprocket and sprayer and the length of the chain can be standardized.

The injection unit 300 includes a sprayer 310 capable of spraying nutrient solution to the roots of plants exposed below the cultivation plate 100, and a nutrient solution recovery facility that can recover and use nutrient solution not absorbed by the roots. include The recovery facility includes a recovery tank for collecting the nutrient solution not absorbed by the roots and a pipe for sending the recovered nutrient solution to the storage tank. The nutrient solution recovery facility applied to the injection unit 300 is not particularly limited, and various structures applied in aerophonic cultivation may all be applied to the extent that the characteristics of the present invention are not impaired.

On the other hand, since there is a difference in the length and shape of the root of each cultivated plant, the distance between the injector 310 and the root of the plant may be a problem. It is also possible to adjust the distance between the injector 310 and the root of the plant by adjusting the length of the connection part 112 of the cultivation board 100, but there is a disadvantage in that precise control is difficult. In addition, it is difficult to adjust the distance between the injector 310 and the root by adjusting the overall height of the transfer unit 200 . In contrast, if the height of the injector 300 or the injector 310 is configured to be adjustable, the distance between the injector 310 and the root can be precisely adjusted and the adjustment is relatively easy.

And since the aerophonic cultivation device according to the present invention is generally installed indoors, a lighting device for plant growth is additionally installed. The lighting device is configured by installing a plurality of light sources (not shown) at positions capable of providing sufficient light to the plurality of redistribution plates 100 . At this time, the distance between the rear plates 100 is determined by the distance between the coupling pins 222 installed on the chain 220, and the position of the lowermost rear plate is determined according to the position of the injector 310. , Since the positions of the other rearing plates are also specified, a light source is installed at a position capable of supplying sufficient light to each of the rearing plates 100.

Since the aerophonic cultivation device according to the present invention is installed indoors, the light source can be fixed to the ceiling or wall, and one end of the light source is fixed to the side wall and the other end protrudes inward (e.g., bar-shaped LED device) can be configured. At this time, if the part fixing the light source to the side wall is configured with a hinge or the like so that the protruding light source can be moved, both installation and management of the light source become easy.

If the light source is arranged so that light is irradiated to each of the multi-layered cultivation plates 100, light may be irradiated to the roots exposed below the cultivation plate, which may have a negative effect on root growth. Therefore, it is preferable to install the light blocking plate 120 surrounding the side of the roots exposed to the lower side of the cultivation plate 100, and the roots grown by installing the anti-sagging net 122 below the light blocking plate 120 It is desirable not to be exposed to the light of the light source out of the influence of the light source. The anti-sag net 122 is composed of a net through which the nutrient solution sprayed from the injector 310 can pass.

A process of performing aerophonic cultivation using the aerophonic cultivation apparatus of the above embodiment will be described.

It is preferable to sequentially proceed with nutrient solution injection (feeding) by tying a predetermined number of cultivation plates 100 into one set. For example, as illustrated, feeding may be performed by bundling 12 rearing plates into one set according to the positions of the rearing plate 100 and the sprocket 210 . In one embodiment, the interval (pitch) between the redistribution plates 100 is 304mm, and the movement time of one pitch is 15 seconds, and the redistribution plates 100 move at a speed of about 20mm/sec. The time the planting plate stops for feeding can be adjusted, and if the stopping time is calculated as 1 minute, the stopping time for feeding for 12 planting plates is 12 minutes, and the time to move 11 times is 161 seconds, so it is about 14.5 minutes. Feeding is performed once. Thereafter, feeding and moving are repeated at the same speed and time while rotating the transfer unit 200 in reverse. In this case, the first cultivation plate is fed again at intervals of about 30 minutes. There is a difference in the feeding interval for each plant to be cultivated. For lettuce, feeding is performed once every 30 minutes, for barley sprouts, feeding is performed once every 4 hours, and for shorter cases, feeding is performed once every 20 minutes. As discussed above, feeding for 1 minute is a suitable interval for lettuce, and in the case of barley sprouts, it is possible to adjust the interval between forward and reverse feeding. If an interval of less than 30 minutes is required, the interval can be shortened by reducing the feeding time. In this way, if specific conditions such as feeding time are set, feeding is performed for a plurality of cultivation plates at appropriate intervals while repeating forward rotation and reverse rotation, so that cultivation can be performed automatically.

In using the aerophonic cultivation device of the present invention, the method of performing feeding by grouping a specific number of cultivation plates into a set has been described, but it is not limited thereto, and the number of cultivation plates grouped into a set, feeding time, moving speed, etc. It can be adjusted and applied in a variety of ways.

In the middle of the refrigerated container, a cultivation unit 2000 with an aerophonic cultivation device was installed, and at the other end, a working unit 3000 capable of performing operations was configured. In general, a 40ft refrigerated container has a length of about 12m and a space for a temperature control facility of about 0.8m, so if an aerophonic cultivation device is installed in a length of 10m, a work unit 3000 with a working space of about 1.2m is formed. can provide

Since the aerophonic cultivation device installed in the cultivation unit 2000 of the present embodiment moves the cultivation plate 100 by the transfer unit 200, the operator sequentially moves the cultivation plate 100 without moving from the work unit 3000. can be installed In addition, since the chain 220 of the transfer unit 200 is composed of one chain and the rearing plate 100 returns to the working unit 3000, the work of recovering the growing rearing board 100 is also carried out by the working unit 3000. ) can be performed.

In the case of constructing an aerophonic system in a standardized refrigeration container, since the size of the space in which the aerophonic cultivation device is installed is specified, the size of the cultivation plate, the installation position of the transfer unit, and the length of the chain are specified. Therefore, parts constituting the aerophonic cultivation apparatus can be mass-produced in a predetermined standard, and an excellent effect of providing an aerophonic system by installing pre-produced parts in a standardized container is exhibited. In addition, it is also possible to configure an aerophonic cultivation complex or a cultivation factory having a plurality of aerophonic systems composed of standardized containers.
