Description

Bed of plant cultivation device {BED OF PLANT CULTIVATION APPARATUS}

The present invention uses the overflow block to arbitrarily increase the nutrient solution level of the bed flow path to smoothly supply the nutrient solution to the seedlings even with a low flow rate, and to lift the overflow block from the bed even when the overflow block is not used. The present invention relates to a bed of a plant cultivation apparatus, which eliminates the need for good management convenience.

Plant plant is a hydroponic cultivation of plants using nutrient solution and lighting equipment in the cultivation room, which is blocked from the outside environment, so that light, temperature, and ventilation are artificially controlled. It has the advantage of being able to supply and manage consistent shape and taste nutrients.

Looking at the configuration of such a plant factory with reference to Figures 1 and 2, the cultivation stage (10A) supported by the frame 20 is formed in multiple stages in the vertical direction and each cultivation stage (10A) bed 10 flowing nutrient solution Is provided with a plurality of lines and the seedling planting plant planted on the bed is located using a formal plate.

The bed 10 is a flow path in which the nutrient solution flows from one side end and is discharged to the other end while maintaining the set water level, and the plant positioned on the bed 10 using the formal plate and the seedling port has its roots flowing through the bed. While absorbing water and nutrients from the water, the roots are also exposed to the air by periodically draining the nutrient solution from the bed to facilitate oxygen supply to the roots.

The nutrient solution is a mixture of the liquid ratio and the raw water at a predetermined ratio in the mixing tank as a nutrient solution tank 51, pump 53, supply pipe 55, a plurality of valves 57, etc. separate nutrient supply device (50) It is supplied and circulated by), and in order to supply oxygen to the roots, the nutrient solution is recovered from the bed periodically and stored in the nutrient solution tank, and the circulation drive may be stopped.

Plants located on the bed 10 grow roots under the seedling port as the growth progresses from the seedling stage of the seedling state, and after the roots grow, the part of the flow path is encroached and the level of the nutrient solution is spontaneously raised. Higher and lower flow rates, but relatively high levels and low flow rates are required in the seedling season before the roots grow to a certain extent because of their short length and weakness of hydraulic stress.

Therefore, during the seedling period, the nutrient level should be high. To this end, when the amount of nutrient solution is increased, there is a problem in that the capacity of the nutrient supply device such as the pump from the nutrient solution tank is increased and the driving energy cost is increased, while the flow velocity is high, which impedes the root growth.

The present invention is to solve the above problems,

It is an object of the present invention to provide a bed of a plant cultivation apparatus that can smoothly supply nutrient solution to seedlings even with a low circulation flow rate by using an overflow block that can arbitrarily increase the nutrient solution level of the bed passage.

It is another object of the present invention to provide a bed of a plant cultivation apparatus that does not need to lift the overflow block from the bed even when the overflow block is not used, so that the management convenience is good.

Hereinafter, an embodiment of the nutrient solution supply system of the plant factory of the present invention will be described in more detail with reference to the accompanying drawings.

In the nutrient solution supply system of the plant factory according to the embodiment of the present invention, as shown in Figures 3 to 6, the root of the plant disposed at the top in the plant cultivation device absorbs the nutrient solution and is introduced through the mouth means (13) In the bed 10 of the plant cultivation apparatus which forms the retention flow passage 11 until the nutrient solution flows out and is discharged to the discharge means 15 (see FIGS. 1 and 2), the discharge means 15 is adjacent to the discharge means 15. An overflow block 30 is installed to increase the level of the nutrient solution at the position.

In this case, the overflow block 30 is a weight that prevents the flow is landed on the bottom surface of the flow path 11 is preferably formed to block a part of the vertical direction in the flow path (11).

To this end, the overflow block 30 is fitted to correspond to the shape of the flow path 11 on the cross section, and the height from the landing surface is at least the same as that of the lower end position of the seedling port 41 coming into the interior space from the top of the bed 10. Or a little high.

 The overflow block 30 may be made of various forms, such as a metal material having strong corrosion resistance and high specific gravity or filled with a heavy material such as sand in a hollow body made of a resin material.

In addition, in order to prevent the nutrient solution from below the flow passage 11, the overflow block 30 has a small flow path 33 through which a nutrient solution can pass through the ground surface 31 contacting the bottom surface of the flow passage 11. desirable.

The small flow path 33 formed in the overflow block 30 is formed as a groove penetrating the ground surface 31 or a through hole adjacent to the ground surface and is made so that a small amount of nutrient solution can pass therethrough.

In addition, the overflow block 30 is preferably formed on either side of the front or rear to block the flow path 11, the conversion pillar 35 for functioning as a pillar when switching posture to protrude to both sides.

The conversion pillar 35 extends in both sides from the overflow block 30 to the front or the rear to block the flow path 11, the length of which is the body portion that blocked the flow path at the 90-degree rotation landing, the bottom surface of the flow path. It is formed so as to be spaced apart from to open the flow path and not interfere with the nutrient solution flow (see FIGS. 7 to 9).

Look at the working state of the bed of the plant cultivation apparatus according to the present invention having the above configuration.

The nutrient solution flowing into the bed 10 through the inlet means of one side is discharged and circulated through the outlet means 15, the nutrient solution level in the bed 10 is set in accordance with the state that the roots have grown to some extent through the seedling period Seedling pot 41 is excreted using a plate 43 on the bed 10 is the lower end is located above the nutrient solution level.

Therefore, the seedlings whose roots are located in the seedling port 41 are cut off from the nutrient solution.

The present invention by installing the overflow block 30 adjacent to the discharge means 15 in the flow path 11 of the bed 10 to raise the nutrient solution level above the height of the overflow block 30, the lower end of the seedling port 41 Soak in the nutrient solution and keep the nutrient solution smooth with low flow rate even during seedling period.

As such, when the overflow block 30 is installed, the nutrient solution located in the lower portion of the flow path may become stagnant and corrupt. As described above, a small amount of flow proceeds by forming a small flow path 33 below the overflow block, and the nutrient solution Congestion and corruption are prevented.

In addition, when the root of the plant grows, the flow path 11 is encroached and the water level is spontaneously increased while the overflow length becomes unnecessary even when the water level is low, so that the overflow block is unnecessary. After moving to another place and plant harvesting new seedlings can be installed to bring the overflow block 30 previously stored.

However, when the overflow block 30 is moved to and fro in this way, storage management is cumbersome and lossy.

The conversion pillar 35 is formed in the overflow block 30 to solve these problems.

The conversion pillar 35 is protruded to either side of the front or rear of the overflow block 30 so that the overflow block 30 lies horizontally on the bottom surface of the flow path when performing the original function of raising the water level. It is in a state that does not have any other effect, but increases the landing stability of the overflow block 30 (see FIGS. 3 to 5).

Then, when the growth of the plant is in progress and the function of the overflow block 30 becomes unnecessary, if you slightly lift the overflow block 30 that was blocking the flow path and rotated 90 degrees, the conversion column 35 is erected and switched to a column. The body portion blocking the flow path is lifted up and the flow path is opened between the two side switching pillars 35 so that the flow of the nutrient solution is prevented (see FIGS. 7 to 9).

In this way, the switching block 35 is provided in the overflow block 30 to change the posture, it is not necessary to lift the bed even when the overflow block is unnecessary, and change the posture whenever a new seedlings come in It can be used repeatedly, and the convenience is very good.

As described above, the bed of the plant cultivation apparatus according to the present invention is provided with an overflow block that can arbitrarily increase the level of nutrient solution in the bed, so that the nutrient solution can be smoothly supplied to the seedlings even with a low circulation flow rate. Since the switching pillar is provided, it does not need to be lifted from the bed by changing the posture even when not in use, and thus there is a good management convenience.
