Description

Descending Flow & Flow Cultivation System

The present invention relates to an end and flow cultivation system, and more particularly to a system capable of raising and lowering pots.

Large amounts of fertilizer use and emissions in greenhouse crop cultivation can lead to soil and surface water contamination in the greenhouse. In order to solve this problem, a circulating irrigation system was introduced, and in the differentiation cultivation, the bottom irrigation system of the Ebb and flow cultivation method, which can produce high quality products while reducing fertilizer and moisture by replacing the conventional head phase irrigation ( Hereinafter, EBB cultivation) method is preferred.

1 is a schematic diagram of an EBB cultivation system according to the prior art.

The nutrient solution supplied from the nutrient solution supply unit 10 is introduced into the lower layer from the pot through the pipe 3 located in the flower pot in the pot 2, and the nutrient solution is transferred to the upper layer of the soil by using the principle of nutrient and moisture to the crop. Supply. (Hereinafter, "nutrient solution" is referred to as including all kinds of feed liquid and the like, including the nutrients and moisture required for the crop.)

When nutrient solution is supplied, it should be supplied to a certain level considering the root of the crop. In addition, after a predetermined time has passed, a new nutrient solution must be supplied after draining the remaining nutrient solution.

The EBB cultivation method provides the roots with the nutrients and moisture necessary for growth without physically stimulating the crop, which has the advantage of saving fertilizer and labor compared to conventional headed irrigation. In addition, the moisture does not adhere to the flowers or leaves can reduce the pests generated during high humidity can produce a product of excellent quality.

However, when applying the EBB cultivation method, due to the above-described nutrient solution supply method, when using the system according to the prior art as shown in Figure 1, enough nutrient solution to the appropriate water level in the space between the pot (2) and the pot (3) A large amount of nutrient solution is consumed in the process of supplying and changing over time.

In addition, the area occupied by the nutrient solution supply part is also not small, and there is a problem of a large amount of space occupied in installing the cultivation apparatus.

Moreover, another problem can arise when installing an EBB cultivation system in the house.

That is, in order to increase the crop yield in the house it is desirable to place a lot of pots, because the space for the worker to work around the pot should be secured, there is a limit to the number of pots that can be installed in the house.

In addition, the temperature in the house is different from the upper layer and the lower layer depending on the day or night or the weather, which is not properly utilized by the technology developed so far.

For this reason, when the EBB cultivation system is applied in the house, there is a problem that there is a limit to the increase in crop yield.

There are a number of patents on EBB cultivation methods.

Korean Patent Publication No. 2003-0011020 discloses a plant cultivator using EBB cultivation. The nutrient solution supply space is formed between the two pots, there is a disadvantage that a large amount of nutrient solution is required instead of taking the structure to increase the water absorption rate.

Korean Patent Publication No. 2010-0052107, which is a patent by the present applicant, discloses an apparatus capable of moving a bed while taking EBB cultivation. Although it is possible to move in parallel for differentiation cultivation, it is difficult to secure the working space of the worker when installed in the house due to the moving structure, and regardless of the decrease in the amount of nutrient solution supplied, the movement is performed only in parallel. There is no consideration of the cultivated growth due to.

U.S. Patent Publication No. 2012-0233918 discloses an EBB cultivation method of increasing water absorption using a blower, but also requires a large amount of nutrient solution and cultivation in the house is not considered.

Ev and flow cultivation system according to the present invention, nutrient solution supply unit 10 for supplying nutrient solution, pollen (100, 200) and cradle 300, the plant is supplied with the nutrient solution is cultivated elevator lift (400) ), And a control unit 500 for controlling the same.

Hereinafter, with reference to the drawings will be described in detail the components of the present invention.

First, the

pots

100 and 200 and the holder 300 will be described with reference to FIGS. 2A to 2D. The

flower pots

100 and 200 are composed of the first flower pot 100 and the second flower pot 200. Note that reference numerals “100, 200” refer to both the first flower pot and the second flower pot.

The first pollen 100 is a space where crops grown by the EBB cultivation method are located.

The first flower pot 100 includes a through hole 130. The through-hole 130 is an inlet through which the nutrient solution stored in the spaced space between the first flowerpot 100 and the second flowerpot 200 is introduced into the first flowerpot 100, and the nutrient solution is again after a predetermined time. It is also an outlet to the space. Preferably, the plurality of through-holes 130 are located, and as shown in FIG. 2B, the holes 130 are spaced apart at regular intervals, but are preferably intersected on both inclined sides.

The second flower pot 200 is overlapped to have a predetermined spaced space outside the first flower pot 100.

The first flower pot 100 and the second flower pot 200 are inclined toward the center, but preferably have a shape corresponding to each other. In the present specification, "shape corresponding" means that the shape of the two pots are the same, so that the space is less spaced apart when the two overlap. Even if the parts are not identical, as compared with the case where the shapes are the same, if the two overlap and there is no difference in the size of the space to which the nutrient solution is supplied, it will also be understood as the corresponding shape.

As shown in FIGS. 2 and 6, the side cross section may be an inverted triangle, and as shown in FIGS. 4 and 5, the side cross section may be an inverted triangle or a polygon.

Due to this arrangement of the shape of the first flower pot 100 and the second flower pot 200 and overlap each other. The space between which the nutrient solution is supplied (temporarily) is very small compared to the prior art, which greatly reduces the amount of nutrient solution to satisfy the appropriate level required by the EBB cultivation method.

The second flower pot 200 includes a drain port 230. After a predetermined time set in the EBB cultivation method, the drain port 230, the nutrient solution in the space between the first planter 100 and the second planter 200, or the nutrient solution remaining in the first planter 100 is again a second The passage is discharged through the flower pot (200). The drain port 230 is connected to the discharge passage 270 so that the discharged nutrient solution flows back to the nutrient solution supply unit 10. Although the location of the drain 230 is not limited, it may be located at the lower end of the second flower pot 200 as shown in FIG. 2C and may be located at the bottom as shown in FIG. 4.

The cradle 300 is located in the space between the first planter 100 and the second planter 200 spaced apart and the nutrient solution is flowable to provide the nutrient solution to the space.

One end of the cradle 300 is connected to the nutrient solution supply unit 10 and supplies the nutrient solution to the space through the other end. To this end, it is preferable that a part of the holder 300 is mounted on the second flower pot 200 and a part of the holder 300 is located in the space. In addition, a plurality of spaced apart at regular intervals is preferred.

The cradle 300 includes a cradle 310 and a supply 350.

The holding unit 310 is connected to the supply passage 370 connected to the nutrient solution supply unit 10 receives the nutrient solution. Since the mounting portion 310 is preferably mounted above the second plant pot 200 and inserted above the second plant pot 200, a shape corresponding to the thickness of the second plant pot 200 is preferable.

The supply unit 350 has a shape in which the mounting unit 310 is extended and is positioned in a space between the first planter 100 and the second planter 200. The nutrient solution flowing from the nutrient solution supply unit 10 through the supply unit 350 flows into the space.

With reference to Figure 2e will be described another embodiment of the pot according to the present invention.

The pollen 100 ', 200' according to the present embodiment may have a 'W' shape by first using the pair of

pollen

100, 200 of the embodiment. That is, the flower pots 100 'and 200' may have an inverted triangle or a polygonal side cross section in a form inclined toward the center direction, and the inverted triangles or polygons may be paired to measure the pots 100 'and 200'. When viewed from the cross section, the shape may be 'W' shaped.

When the load of the pollen 100 ', 200' is lower than the load due to soil and plants and the size of the crop is relatively small, first, in the case of the

pollen

100, 200 of the embodiment, the portion occupied by the relatively small crop Compared to the total space of the pots (100, 200) can be large and inefficient, compared to other embodiments, pots (100 ', 200') provides only the space corresponding to the pots of the relatively small crop and more It can provide space for growing crops.

Nutrient supply is carried out in the following manner.

The nutrient solution is supplied to the space spaced between the first potted plant 100 and the second potted plant 200 through the mounting unit 300 connected to the nutrient solution supply unit 10 and the supply passage 370. Since the space between the first planter 100 and the second planter 200 is very small, the nutrient solution of the appropriate level required in the EBB cultivation method is satisfied in a small amount within a short time.

The nutrient solution provided is supplied into the first flower pot 100 through the through hole 130 of the first flower pot 100.

After a certain period of time required for the EBB cultivation method, the nutrient solution stored in the space between the first flower pot 100 and the second flower pot 200 is again passed through the passage connected to the drain port 230 to the nutrient solution supply unit 10. Go back

Next, the elevator 400 and the controller 500 will be described with reference to FIG. 3.

The elevator 400 serves to move the

pots

100 and 200 up and down.

The eb and flow cultivation system according to the present invention is preferably installed in the house, because the temperature in the house is different up and down temperature according to day and night. In other words, by finding the most desirable temperature for crop growth, the pollen moves up and down, which greatly increases crop yield.

In addition, the

plant pots

100 and 200 may move up and down to secure a work space for the worker. If there is no vertical movement, there is a space for the worker to move and work between the pots (100, 200) and other pots (100, 200), and if it is possible to move up and down other pots adjacent to the pots (100, 200) You can work in the space after raising (100, 200). This allows

more pots

100 and 200 to be placed in houses of the same area, thus greatly increasing crop yield.

The elevator 400 may have any structure for raising and lowering the

flower pots

100 and 200. As shown in FIG. 5, the elevating bar 420 may be raised and lowered, and as shown in FIG. 6, a pulley 440 may be used to wind the elevating line 430. However, it should be noted that the principle of elevating and descending in any manner is not limited to such a structure.

The controller 500 is electrically connected to the database 510, the control panel 520, and the sensor 530.

In the database 510, temperatures suitable for crops and crop growth are mapped and stored in advance.

The control panel 520 includes an input / output unit for the operator to control the elevator 400 and / or the nutrient solution supply unit 10.

In addition, the temperature in the house measured by the plurality of sensors 530 may be output. The plurality of sensors are preferably located in the longitudinal direction in the house, so that the temperature according to the height in the house can be measured and output.

In addition, the operator may store or change crops and temperatures in the database 510 using the control panel 520.

In addition, the control panel 520 may further output weather information, information on whether the house is opened or closed, so as to output and control various types of information in the house where the EB & F cultivation system is installed.

In FIGS. 5 and 6, the elevator 400 and the control panel 510 are integrated with the controller 500, but this is only an example and other structures are possible. In addition, it is a matter of course that a plurality of houses can be managed together in one control unit 500 and the control panel 510.

Control is done in the following manner.

As a first embodiment of the control, the worker can selectively raise and lower the

pots

100 and 200 desired by the worker, so that the worker can secure a work space.

That is, when the worker selects the pots 100 and 200 (generally different pots adjacent to the pots to be worked) to be raised and lowered by the control panel 520, the control unit 500 controls the

pots

100 and 200. The elevator 400 is driven to operate the connected lifting bar 420 or the vertical lifting wire 430, and thus the

flower pots

100 and 200 are lifted up and down.

As a second embodiment of the control, all

pots

100 and 200 can be raised or lowered manually or automatically to a height corresponding to the temperature suitable for the crop.

In the case of manual control, when the operator selects the lifting or lowering in the control panel 520, the control unit 500 is raised to operate the lifting bar 420 or the vertical lifting wire 430 connected to the corresponding pots (100, 200) Driving the descender 400, accordingly all the pots (100, 200) are raised or lowered.

In the case of relatively simple automatic control, the

pots

100 and 200 may be automatically lowered according to the day or night. This is because the daytime temperatures are higher in the house and the nighttime temperatures are lower in the house. The control unit 500 is equipped with a module for checking the time, it is possible to check whether it is day or night, in the case of crops desirable to grow at a higher temperature, the pots (100, 200) are located in the upper layer during the day and the lower layer during the day It can be automatically controlled to be located at.

As another automatic control, the

pots

100 and 200 may be raised and lowered according to the angle of incidence of sunlight incident on the house where the cultivation photo assembly is installed and the east and west positions of the

pots

100 and 200. Here, the incident angle of sunlight refers to an angle formed by a straight line and a horizontal line connecting the sun at the point where the pollen (100, 200) is located, and the east-west position refers to the relative direction between the pollen (100, 200). As a reference, it indicates whether one pot is located in the west or the east compared to the other pot.

For example, in the morning, the solar incident angle of the potted

plants

100 and 200 located in the east in the house where the cultivation photo assembly is installed is different from the solar incident angle of the potted

plants

100 and 200 located in the west. In the absence of rising and falling, there is an imbalance in which the potted plant in the east receives more incident than the potted plant in the west. The evening is the opposite of the above. The present invention can adjust the lifting height according to the angle of incidence and the east-west position of sunlight in order to solve such an imbalance. In other words, in the morning, by raising and lowering the potted plants (100, 200) in the west, the incident angle of sunlight can be widened, and the amount of incidence can be increased by deviating from the obstruction by the potted plants (100, 200) in the east. In an opposite manner, an imbalance in the amount of incidence between the

pots

100 and 200 may be eliminated.

As another automatic control, it can be ascended and lowered to an appropriate height depending on the crop. When a worker inputs crops to be cultivated through the control panel 520, the controller 500 checks the crops and the crop growth temperature stored in advance by being mapped to the database 510, and the plurality of sensors 530 installed in the longitudinal direction. After checking the sensor that is measured closest to the crop growth temperature of the temperature measured by), the elevator 400 may be operated to be located in the pots (100, 200) at the height of the sensor.

4 and 5, a first embodiment of a system according to the present invention will now be described. In FIG. 4 and FIG. 5, the illustration of the first flower pot 100 is omitted for reference, but as described above, it is preferable that the shape of the first flower pot 100 corresponds to the shape of the second flower pot 200. to be.

Both sides of the second flower pot 400 is provided with a lifting bar support 210. The elevating bar support part 210 serves to receive a load during the elevating of the

flower pots

100 and 200 by being supported by the elevating bar 420 extending horizontally from the sides of the

flower pots

100 and 200.

The elevating unit 400 raises and lowers the elevating bar 420 under the control of the control unit 500, and thus the

flower pots

100 and 200 are raised and lowered by the elevating rod support 210 on the elevating unit 400. .

Compared with the second embodiment (Figs. 6 and 7) described later, it has the advantage of being structurally safe.

A plurality of ribs 220 are provided inside the second flower pot 400 so as to be spaced apart at predetermined intervals and protrude into the second flower pot 200. When soil is contained in the pots (100, 200), the lateral load is increased, considering the power of the elevator 400, while constructing the pots (100, 200) with a lightweight material and at the same time receiving the lateral load applied by the soil structural stability It serves to add.

Next, referring to Figures 6 and 7, a second embodiment of a system according to the present invention will be described.

The rotatable pulley 440 is installed on a fixed structure in the house in which the

flower pots

100 and 200 are installed, and the lifting and lowering line 430 may be wound or unwound. Lifting line 430 is fixed to the pots (100, 200) through the connection line 450, in particular it is preferably fixed to the second pot (200).

The elevating unit 400 rotates the pulley 440 under the control of the control unit 500, and thus the elevating line 430 wound around the pulley 440 is wound or unwound, thereby raising the

pots

100 and 200. Descends.

Compared with the above-described first embodiment (Figs. 4 and 5), the structure is simple and the installation and maintenance costs are low.

It is preferable that a plurality of structural reinforcing lines 225 are further provided on the upper side of the

pots

100 and 200 to be spaced at predetermined intervals to support the

pots

100 and 200 from left and right to compensate for the lateral load caused by the soil. In particular, as shown, a plurality of structural reinforcing wire 225 is provided in the second pot 200 is preferably installed above the first pot 100.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
