Abstract

<P>PROBLEM TO BE SOLVED: To improve operation efficiency by directly feeding liquid nutritient for plant cultivation in a prescribed amount matching to the growth of a plant dropwise to a plant carrier, circulating the excess liquid nutritient by a pump so that the roots of the plant is exposed to air, and decreasing the amount or the number of used plant carrier, liquid nutritient, articles of consumption, machine parts. <P>SOLUTION: Net-shaped shallow unevenness is formed on the bottom surface in a cultivation container. Grooves are formed at the periphery of the bottom, and draining holes are formed in the grooves. The liquid nutritient from the tank is fed dropwise to the plant carrier in the cultivation container by connecting a liquid-feeding pipe having small holes for feeding the nutrient to the tank by a pipe or a hose so that the nutritient is given to the roots of the plant. The shallow unevenness enables the nutritious liquid accumulated in the net-shaped shallow unevenness on the bottom surface of the cultivation container to be given to the roots of the grown plant, and the roots to be exposed to the air. The excess nutritious liquid is recovered and stored in a nutritious liquid-recovering tank connected to the nutritious liquid tank by a pump and a pipe, and recycled to the nutritious liquid tank in the apparatus for water culture. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydroponic cultivation apparatus which constantly supplies an appropriate amount of hydroponic nutrient solution to a plurality of hydroponic plants or the like while minimizing the use of electric power. It is a thing.

[0002]

2. Description of the Related Art Conventionally, there are many technologies relating to hydroponic cultivation apparatuses, but many of them are complicated, large-scale and expensive.

[0003]

According to the conventional method, many of the devices are complicated and large-scaled such as computer processing of information from various sensors, video information, etc., resulting in high cost, small and medium scale. I didn't go to the growers.

[0004]

[Means for Solving the Problems] The present invention makes it possible to freely determine the scale of a cultivating device by unitizing a cultivating container, and minimizes the use of electric power to constantly provide an appropriate amount of nutrient solution. The above problem is solved by supplying liquid efficiently and inexpensively.

[0005]

(1) A hydroponic nutrient solution is dripped and supplied to an optimum position of a plant carrier in which a plant is planted, through a liquid supply pipe that can be moved according to the growth from the beginning of growth. (2) A required amount of the nutrient solution is held in a water-permeable plant carrier, which supplies nutrients to the plant roots, and the plant carrier made of a porous material brings the roots of cultivated plants into contact with air. (3) The mesh-shaped unevenness on the bottom surface of the cultivation container retains the nutrient solution to supply nutrients to the roots of the cultivated plant that grows and extends from the plant carrier, and brings the roots into contact with the air. (4) Even if the temperature of the nutrient solution tank rises, the solution is dripped and cooled by the plant carrier, and the nutrient solution remaining in the mesh-like unevenness is naturally cooled and has no adverse effect on the cultivated plant.

[0006]

EXAMPLES Examples of the present invention will be described below. (1) The nutrient solution 2 is connected from the nutrient solution tank 1 to the plurality of solution supply pipes 5 by the pipe 3 and the hose 4, and the flow rate is adjusted by the faucet 6 while the solution is dripped onto the plant carrier 8 in the cultivation container 7. To do. (2) Small holes 9 are provided on the upper side of the liquid supply pipe 5 in accordance with the average planting interval of plants. (3) Shallow mesh-like unevenness 1 on the bottom surface 10 in the cultivation container 7.
1 is provided, a groove 12 lower than the bottom surface 10 is provided in the periphery, a drainage hole 13 is provided in the groove 12, and the nutrient solution is recovered via a gutter 14 that is installed separately from the cultivation container 7 under the work table 27. Connect to tank 15. (4) Stands 19 for holding plants are set up in the pillar holes 18 of the upper edge 16 and the lower edge 17 of the cultivation container 7. (5) The nutrient solution recovery tank 15 is connected to the nutrient solution tank 1 by the pump 21 and the pipe 3 that pump up the nutrient solution 2 controlled by the water level sensor 20 of the nutrient solution tank 1. (6) Ball tap 2 from the water pipe 22 to the nutrient solution recovery tank 15
A water supply port 24 controlled by 3 is provided. (7) The plant carrier 8 is covered with the sheet 25 or the lid 26 for preventing the roots from drying out. The hydroponic cultivation device 28 configured as described above.

The present invention, when using the above structure, (1) fills the nutrient solution tank with a nutrient solution having a concentration suitable for the cultivated plant, and adjusts the position of the liquid supply pipe and the faucet. An appropriate amount is added dropwise to the plant carrier according to the growth of the plant. (2) While installing the required number of cultivation containers on the cultivation scale,
Cover the roots with a sheet or lid to prevent evaporation, and set up support posts to hold the plants in the support holes to protect the plants. (3) Excess nutrient solution flowing out from the plant carrier and the mesh-shaped irregularities is collected in the nutrient solution recovery tank and circulated in the nutrient solution tank by a pump. (4) The consumption of nutrient solution is automatically replenished from the water inlet,
Adjust the nutrient solution concentration and supply volume manually.

EFFECTS OF THE INVENTION (1) A required amount of nutrient solution and air can be efficiently supplied according to the growth of plants. (2) The number of cultivation containers can be increased or decreased according to the production scale, and the device is inexpensive. (3) The nutrient solution is naturally cooled by the dropping liquid supply, and cooling of the nutrient solution tank or the like is unnecessary. (4) Consumables other than plant carrier, nutrient solution, and water are unnecessary, and the operation efficiency is high. (5) The cultivation container and nutrient solution circulation system are separated,
High work efficiency during cleaning.
