Abstract

PURPOSE:To easily increase the cultivation capacity and enable the culture without causing growth inhibition by guiding a hydroponic liquid over-flowed from a culture tank of a main culture apparatus to a culture tank of a subsidiary culture apparatus through a flow channel and connecting both culture tanks with each other through the other flow channel. CONSTITUTION:In the case of culture using only a main culture apparatus A, the discharging port 5a of a hydroponic liquid take-up cylinder 5 is closed with a plug 6, a cultivation hydroponic liquid is charged from a hydroponic liquid tank 1 to a culture tank 2 and a pump 3 is driven to supply the hydroponic liquid to one end of the culture tank 2. When a prescribed amount of the hydroponic liquid is stored in the culture tank 2, the liquid is over-flowed over a wall 2a opposite to the pump 3 and returned to the hydroponic liquid tank 1. A plant is cultured by wrapping the root of a culture plant with a holding member 14 such as foamed urethane material and inserting the wrapped root into a hole of a planting panel 12 acting also as a cover of the culture tank 2. In the case of culture using the subsidiary culture apparatus B in addition to the main culture apparatus, the culture apparatus B is place adjacent to the main culture apparatus A and connection pipes 10, 11 are used to connect a discharging port 5a to the culture tank 7 and a flow channel 8 to the hydroponic liquid tank 1. The hydroponic liquid over-flowed from the culture tank 2 of the main culture apparatus A is introduced into the culture tank 7 of the subsidiary culture apparatus B and returned to the hydroponic liquid tank 1 through the flow channel 8.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a simple hydroponic cultivation device for home use.

Conventional technology Conventionally, a cultivation tank was installed above a nutrient tank for storing cultivation nutrient solution, in which the nutrient solution pumped up from the nutrient solution tank was allowed to flow and collected to cultivate plants. Hydroponic cultivation devices have been known.

Problems to be Solved by the Invention The conventional type has the disadvantage that a small or large cultivation device must be selected and purchased depending on the amount to be cultivated.
Even if you select and purchase a hydroponic system, if you are cultivating for multiple years, you will not be able to obtain a cultivation tank that can match the amount of cultivation and you will have to purchase another hydroponic cultivation device, which is extremely uneconomical.6 Problems Means for Solving the Problems The present invention has taken the following technical means to solve the above problems.

That is, the present invention provides a cultivation tank in which the nutrient solution pumped up by the pump 3 from the nutrient solution tank 1 is flowed and stored on the upper side of the nutrient solution tank 1 in which the cultivation nutrient solution is stored, thereby cultivating plants. 2, and a sub-cultivator B having a cultivation tank 7 lower than the bottom of the cultivation tank 2 adjacent to the main cultivation device A which directly returns the nutrient solution overflowing from the cultivation tank 2 to the lower nutrient solution tank 1. The cultivation tank 2 of the main cultivation device A and the cultivation tank 7 of the sub-cultivation device B are provided with a flow path for guiding the nutrient solution overflowing from the former cultivation tank 2 to the latter cultivation tank 7,
The latter cultivation tank 7 side and the nutrient solution tank 1 of the main cultivation device A are appropriately communicated with each other through a separate flow path to provide a hydroponic cultivation device.

Effects and Effects of the Invention According to this invention, the cultivation capacity can be increased simply by connecting the simple sub-cultivator B, which does not have a pump 3, to the main cultivator A, and furthermore, this sub-cultivator B can be used as the main cultivator. Since it does not overlap with the upper side of A, the cultivated plants receive sufficient sunlight and can be cultivated without hindering their growth.

In Example A, the main cultivator has a primary configuration. 1 is a rectangular nutrient solution tank that contains a cultivation nutrient solution. 2 is the nutrient solution tank 1
This is a cultivation tank whose narrow width side is fitted and supported by the upper part of the tank, and whose longitudinal side is shorter than that of the nutrient solution tank. 3 is a pump that lifts up the nutrient solution in the nutrient solution tank 1 and supplies it into the cultivation tank 2. Reference numeral 4 denotes a nutrient solution return port formed on the opposite side in the longitudinal direction from the pump 3, and the wall frame 2a on the side opposite to the pump of the cultivation tank 2 is made slightly lower than the other wall frames, so that the nutrient solution returning port can be opened from this wall frame 2a. The overflowing nutrient solution is designed to fall and be discharged directly into the nutrient solution tank 1 at the bottom.

Reference numeral 5 denotes a nutrient solution extraction cylinder, the base of which communicates with the upper position on the wall frame 2a side of the cultivation tank 2, the tip of which pierces the nutrient solution tank 1 and projects to the outside, and a stopper 6 is provided at the outlet 5a. ing. When the discharge port 5a is closed with this stopper 6, the nutrient solution overflowing from the wall frame 2a of the cultivation tank 1 is allowed to fall and be discharged directly into the nutrient solution tank 1 at the bottom, as described above. When the outlet 5a is opened, the nutrient solution in the cultivation tank 1 is taken out from the outlet 5a.

B is an auxiliary cultivator, which has a channel 8 at the bottom of the cultivation tank 7 for returning the nutrient solution.
The cultivation tank 7 is installed on the stand 9 so that the height of the bottom surface (A) is lower than the height of the nutrient solution outlet 5a of the cultivation tank 2 of the main cultivation device A, and the flow path 8 is The bottom surface of the tank 1 is also
It is higher than the bottom of the.

10.11 is a connecting pipe, and the pipe 10 is connected to the outlet 5.
a and the cultivation tank 7, and the pipe 11 communicates the flow path 8 with the nutrient solution tank 1 of the main cultivation machine A.

Reference numerals 12 and 13 denote planting panels which cover the two parts of the cultivation tanks 2 and 7 and have holes for planting the plants so as to hold the root sides of the plants.

To explain the operation of the upper side, when cultivating only with the main cultivator A, put a stopper 6 in the outlet 5a of the nutrient solution take-out tube 5, put the cultivation nutrient solution into the nutrient solution tank 1, and then turn on the pump 3. When you start the nutrient solution and send the nutrient solution to one end side of the cultivation tank 2, the nutrient solution will flow into this cultivation WI.
A certain amount is stored in the nutrient solution tank 2, overflows from the wall frame 2a on the opposite side from the pump 1, and is returned to the nutrient solution tank 1. In this way, the nutrient solution is circulated, and the roots of the cultivated plants are inserted into the holes of the planting panel 12, which also serves as the cover of the cultivation tank 2, with the holding member 14 made of urethane foam material, etc., and the cultivated plants are cultivated. The roots then suck up the nutrients from the constantly flowing nutrient solution, causing the plant to grow.

Next, in order to cultivate with the subcultivator B, this cultivator B is placed adjacent to the main cultivator A and connected to the outlet 5a through the connecting pipes 10 and 11.
When the cultivation tank 7 and the flow path 8 are communicated with the nutrient solution tank 1, the nutrient solution overflowing from the cultivation tank 2 of the main cultivation device A is sent to the cultivation tank 7 of the sub-cultivation device B and passes through the flow path 8. It is refluxed into the nutrient solution tank 1. Therefore, by inserting the root of the cultivated plant into the hole of the planting panel 13 of the cultivation tank 7 while wrapping it with the holding member 14 made of urethane foam, cultivation can be performed using the subcultivator B as well.

In addition, if the same structure is constructed between this sub-cultivator B and other sub-cultivators, a large number of sub-cultivators can be connected to the main cultivator A. That is, the nutrient solution flowing from the cultivation tank 7 of the sub-cultivator B to the flow path 8 may be sent to the cultivation tanks of other sub-cultivators.

The height of the sub-cultivator B is adjusted by the stand 9, which can be freely bent in any direction by the stand 9a of the main cultivator A and the stand 9b of the sub-cultivator B at one corner. When connected with the universal joint 15, the stand 9a overlaps the stand 9b and becomes a stand for only the main cultivator A, and can be placed side by side or bent in plan view. It can be selectively arranged.

In addition, when a fish culture tank 16 for keeping goldfish etc. is provided in the main cultivator A, the nutrient solution tank 1 is divided into two parts or has a double structure as shown in FIGS. 4 and 5. A single motor 17 drives two pumps 18a and 18b, and the pump 18a is used for cultivation, and the pump 18b sucks up water from the fish tank 16 to a leakage tank 19 installed next to the cultivation tank 2. It is configured so that it passes through a layer of glass fiber leakage material and activated carbon particles packed in this leakage tank 19 and is returned to the fish culture tank 16 (in other words, it is possible to cultivate fish at the same time as cultivating plants). You can also enjoy it.
