Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plant cultivation device that irradiates plants in the process of growing with artificial light in a plant cultivation room where plant growth conditions such as temperature and carbon dioxide concentration are properly controlled. The present invention relates to a plant cultivation device suitable for growing plants.

A conventional plant cultivation device will be explained with reference to FIG.

In FIG. 1, in a plant cultivation room 10, a water incubator 11 in which plants in the middle of growth are planted is connected to a sprocket 13 in which a plurality of endless track chains 12 are installed.
A large number of water incubator conveyors are suspended from a chain 12 of a water incubator conveying device, which is meshed with a sprocket 13 and is moved by the rotation of a sprocket 13. Further, a plurality of artificial light lamps are attached to the ceiling of the plant cultivation room 10 via holders 14.

The water incubator 11 is transported together with a chain 12 that moves by the rotation of the sprocket 13 at least once a day, and during that time, the plants planted in the water incubator 11 are illuminated by an artificial light lamp. From 15 onwards, they are exposed to artificial light and grown. In this case, plant growth conditions such as temperature and carbon dioxide concentration in the plant cultivation chamber 10 are appropriately controlled. After a predetermined growing period, fully grown plants are removed from the water incubator 11 and transported outside the plant cultivation room 10 to be harvested. In the water tank 11 from which the plants have been removed, plants that are in the middle of growing are newly planted, and then grown and harvested in the same manner as described above.

Such plant cultivation devices have the following drawbacks.

(1) When irradiating artificial light from an artificial light lamp, shaded areas occur and the irradiation of artificial light to plants that are still growing becomes uneven, resulting in a longer growing period for cultivated plants and the need for water nutrient suspension suspended from chains. Despite the large number of containers, the yield is small.

(2) The structure of the water incubator conveying device is complicated, the number of parts is large, and a tall plant cultivation chamber must be installed, which increases the price of the plant cultivation device.

(3) Since the volume of the plant cultivation room is large, the cost of air conditioning to adjust the temperature of the plant cultivation room to an appropriate temperature is high, and the water incubator needs to be transported in short cycles, so it is difficult to transport the water incubator. The driving cost of the device increases, and the operating cost of the plant cultivation device increases.

(4) Harvesting and planting work is troublesome because the location of the water tank in which harvestable plants are planted is uncertain.

The present invention is aimed at eliminating the above-mentioned drawbacks, and includes installing the water incubator conveying device that can be horizontally moved in accordance with the degree of growth of the plants in the middle of growing in a plant cultivation room, and An artificial light lamp movable device is installed on the ceiling of the plant cultivation room to change the relative position of the artificial light lamp with respect to the plants and to change the irradiation angle. It is an object of the present invention to provide a plant cultivation device that can improve the plant cultivation system, reduce the price of the plant cultivation device, and reduce operating costs, and also allows easy harvesting and planting operations.

An embodiment of the present invention will be described with reference to FIGS. 2 and 3.

FIG. 2 is a block diagram of the plant cultivation apparatus according to the present invention. Inside the plant cultivation chamber 10', there is a belt pulley 16 rotatably provided on both sides, and an infinite A water incubator conveying device consisting of a track belt 17 is installed, and an artificial light lamp movable device having an artificial light lamp 15 attached to the ceiling of the plant cultivation room 10', for example,
A plurality of artificial light lamp swinging devices 20 are installed. Here, the artificial light lamp swinging device 20 is as follows:
As shown in FIG. 3, a swing arm 22 has one end swingably attached to a hanging fixture 21 provided on the ceiling of the plant cultivation room 10', and an artificial light lamp 15 attached to the other end; Reciprocating device 2 attached to a mounting seat 23 provided on the ceiling of the plant cultivation room 10'
4, and a swinging arm 22 that reciprocates with a reciprocating device 24.
It is composed of a swing shaft 25 that swings. In addition, on the belt 17 of the water incubator conveying device, the water incubator 11 with plants in the middle of growing is placed from one end to the other end (from the left end to the right end in FIG. 2) according to the degree of plant growth. ' are placed sequentially.

First, the belt 17 moves horizontally (from left to right in FIG. 2) by the rotation of the belt wheel 16, in which the water incubator 11' in which plants that are in the process of growing is planted
placed on one end of the top. Plants in the process of growing that have been planted in the water incubator 11' placed on the belt 17 are irradiated with artificial light from the artificial light lamp 15 which is being swung by the artificial light lamp oscillating device 18. It will be cultivated. When this growth has progressed to a certain extent, the belt 17 is moved horizontally, and then another water incubator 11' in which a plant that is currently growing is newly planted is placed on one end of the belt 17. In this way, the belt 17 is sequentially moved horizontally in accordance with the degree of growth of the cultivated plants, and the water incubator 1 in which a plant that is in the middle of growing is planted at one end of the belt 17 is created.
1' are placed one after another. Thereafter, after a predetermined growing period has elapsed, plants that have grown sufficiently are removed from the other end of the belt 17 and transported outside the plant cultivation room 10' to be harvested. Water tank 1 with plants planted on the way
1' is placed. Such a cycle is repeated, and fully grown cultivated plants are continuously harvested.

In the plant cultivation device of this embodiment, the relative position of the artificial light lamp 15 with respect to the plant is changed by swinging the artificial light lamp 15, and the plant is irradiated from the artificial light lamp 15. Since the irradiation angle of the artificial light is changed, the cultivated plants can be evenly irradiated with artificial light without creating shaded areas on the plants. Therefore, the period for growing plants can be significantly shortened, and the structure of the water incubator conveyor can be simplified by horizontal movement of the belt, the number of parts can be significantly reduced, and the height of the plant cultivation room can be reduced. Can be made lower. Furthermore, since the water incubator only needs to be transported one step during the growing period, the number of times the water incubator is transported by the water incubator transport device can be reduced.

In addition, in this example, an example in which an artificial light lamp is swung by an artificial light lamp oscillating device has been described, but the present invention is not limited to this. The artificial light lamp may be moved so that the artificial light is evenly applied to the area.

As explained above, the present invention installs in a plant cultivation room a water incubator conveying device that can be moved horizontally according to the degree of plant growth, and also has a movable artificial light lamp attached to it. By installing the device on the ceiling of the plant cultivation room, the following effects can be obtained.

(1) Since artificial light can be applied evenly to plants in the middle of growth without creating shaded areas, the growing period of plants can be significantly shortened, and since they can be grown and harvested in succession, the yield of plants can be reduced. can be improved.

(2) The structure of the water incubator conveying device can be simplified, the number of parts can be significantly reduced, and the height of the plant cultivation chamber can be lowered, so the price of the plant cultivation device can be reduced.

(3) By reducing the volume of the plant cultivation room, air conditioning costs can be reduced, and by reducing the number of times the water incubator is transported, the operating cost of the water incubator transport device can also be reduced, which reduces the operating cost of the plant cultivation device. be able to.

(4) Since plants that are in the process of growing can be planted and mature plants can be harvested at a fixed location, plant cultivation work can be facilitated.
