Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an apparatus for efficiently cultivating plants without using soil. INDUSTRIAL APPLICABILITY The device of the present invention is suitable for use as a cultivating device for large-scale equipment such as a plant factory, and a small cultivating device for ships and households.

[Conventional technology]

Conventionally, a part corresponding to the underground part of the plant, that is, only the root part is set in a container that can be sealed, and a nutrient solution containing various elements necessary for plant growth is sprayed to this part, thereby cultivating the plant It has been known.

[Problems to be solved by the invention]

However, in the above-mentioned conventional cultivation apparatus, there are cases in which the temperature inside the container gradually rises to a high temperature, which is unfavorable for plant growth. Especially, there is a disadvantage that it may become unable to grow in summer or high temperature.

The present invention has been made in view of the above points, and an object of the present invention is to provide a plant cultivating apparatus that forcibly takes in air into the portion where the nutrient solution is sprayed, and lowers the temperature in the container by the heat of vaporization. It is a thing.

[Means for solving problems]

The plant cultivation device of the present invention will be described with reference to the drawings.
In a device for cultivating a plant, a root part 10 of a plant is fixed in a container 1 that can be hermetically sealed, and a nutrient solution containing various elements necessary for plant growth is sprayed on the root part of the container 1 in the bottom part of the container 1. A nutrient solution tank 6 consisting of a large-diameter pipe 5 with at least a part of the upper part opened is installed, and a spray pipe 11 is provided in the vicinity of the root part.
The above-mentioned nutrient solution tank 6 and the pipe 1 provided with the nutrient solution pump 12
3 is provided, and an inclined receiving plate 14 is provided so that the nutrient solution flowing down from the spray pipe 11 and the root portion 10 flows into the upper opening 4 of the nutrient solution tank 6, while external air is forced into the container. The air fans 18 and 30 for cooling the root part and the vicinity of the spray pipe are installed, and a water tank 21 is further installed. The water tank and the pipe 1 for the nutrient solution pump
3 and 3 are connected by a capillary pipe 22 for replenishing insufficient water due to evaporation of water in the nutrient solution.

It is desirable that the container has a movable structure and a connectable structure.

[Action]

Air is taken into the container 1 by the fan 18 to cool the inside of the container and lower the temperature. Further, when the nutrient solution pump 12 is operating, water is replenished from the water tank 21 into the nutrient solution via the capillary pipe 22 to prevent concentration of the nutrient solution by evaporation of water. The nutrient solution flowing down from the spray pipe 11 and the root portion 10 is returned to the nutrient solution tank 6 by the inclined receiving plate 14.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the shape of the components described in this embodiment, the relative arrangement, etc., are not intended to limit the scope of the present invention to only those unless otherwise specified, and are merely examples of explanation. Only.

1 to 3 show an embodiment of the plant cultivation device of the present invention. Reference numeral 1 denotes a sealable container, which is covered with a heat insulating material 2 and installed on a pedestal 3. At the bottom of this container 1, a nutrient solution tank 6 consisting of a large-diameter pipe 5 having an opening 4 at the top is installed. In addition, a planting port 7 is provided on the upper surface of the container 1, and only the root portion 10 of the plant 8 is positioned and fixed from the planting port 7 in the container. This root 1
The spray pipe 11 is provided in the vicinity of 0, and the spray pipe 1
1 and the nutrient solution tank 6 are connected by a pipe 13 equipped with a nutrient solution pump 12. The bottom plate of the container 1 is a spray pipe 11
Further, the inclined receiving plate 14 is formed so that the nutrient solution flowing down from the root portion 10 flows into the opening 4 at the upper portion of the nutrient solution tank.

An air inlet 16 provided with a damper 15 is provided on one end side surface of the container 1, and an air outlet 20 provided with a damper 17 and a fan 18 is provided on the other end side surface of the container 1. Further, a water tank 21 is installed in the gantry 3, and this water tank and the pipe 13 of the nutrient solution pump 12 are connected by a capillary pipe 22. 23 is an attracting rod, 24 is an attracting rod support, 25 is a caster, and 26 is a demister.

In the plant cultivation device configured as described above, in order to lower the temperature in the closed container 1, the outside air is forcibly taken in by the fan 18. In this case, it is desirable that the nutrient solution pump 12 and the fan 18 be configured to operate at the same time so that cooling is performed only when the nutrient solution pump 12 is operating.

Further, when the nutrient solution pump 12 is operating, water is replenished into the nutrient solution from the capillary pipe 22, and it is possible to prevent concentration due to evaporation of water in the nutrient solution. Further, it is desirable that the spray interval is controlled by a timer.

FIG. 4 shows a state in which a plurality of unitized devices of the present invention are connected and used. Reference numeral 27 is an air duct connecting pipe, and 28 is a nutrient solution tank connecting pipe.

Next, another embodiment of the device of the present invention will be described with reference to FIG. In the apparatus of this example, an air fan 30 is provided outside the container 1, and air is introduced into the container by an air duct 31. Reference numeral 32 is a nutrient solution inlet, and 33 is a control panel having a timer, a switch and the like. As shown in FIG. 6, the planting port 7 has a vortex line 34 made of plastic, metal or the like, so that it can be fixed even if the diameter of the plant stem is small or thick. Other configurations are the same as those in the case of FIGS. 1 to 4.

[Effect of device]

Since the plant cultivating apparatus of the present invention is configured as described above, it is possible to lower the temperature inside the container by forcedly taking in air, and it is possible to cultivate even in the summer or at high temperature. In addition, the device is unitized to include a nutrient solution tank, so it can be used as a small cultivation device using one unit, and if it has a connectable structure, a large number of devices can be connected to form a large scale. It can also be a cultivation device. Furthermore, it can be used for simultaneous cultivation of many varieties, and if casters are provided, it can be moved during cultivation.
