Problems solved by technology

[0007] But in this case, although the pumps P1 and P2 can be set as pumps with fixed suction and discharge directions, the supply channel of the communication tank 3 must be additionally set 13 and the pump P2 for supply, so there are defects that the manufacturing cost increases and the structure is complicated

Embodiment 1

[0041] Fig. 1 shows the plant cultivating device of the present invention, in which the resin cultivation container 1 which can cultivate plant A is communicated with the connection passage 4 of the tank 3 which can store the fertilizer component and the bactericidal component of plant A dissolved in water. In this case, a pump P that can be freely switched between the state of supplying the storage liquid (cultivation liquid) 5 in the tank 3 to the cultivation container 1 and the state of supplying the cultivation liquid to the cultivation container 1 is provided. The remaining liquid 6 in the tank 2 and the state in which the ventilation air 7 bubbling in the stored liquid 5 flows into the tank 3 can be freely switched.

[0042] The inboard bottom of above-mentioned cultivation container 1 is provided with perforated plate 8, and the substratum 9 that plant cultivation is used is placed on the upper side of perforated plate 8, for example is the natural substratum such as cul...

Embodiment 2

[0049] Fig. 3 shows a second embodiment of the plant cultivation device of the present invention. In this second embodiment, a three-way valve 20 is provided at a branch connection portion between the supply passage 12 and the connection passage 4 instead of the switching portion 16 of the above-mentioned first embodiment. Other structures are the same as those of the plant cultivation device of the first embodiment.

[0050] In the plant cultivating device of the second embodiment, by switching the three-way valve, it is possible to freely switch between the state in which the supply passage 12 communicates with the tank 3 and the state in which the connecting passage 4 communicates with the tank 3 . In this case, since there is no need to provide two check valves as in the first embodiment described above, the structure of the plant cultivation apparatus can be simplified.

Embodiment 3

[0052] Fig. 4 shows a third embodiment of the plant cultivation device of the present invention. In this third embodiment, two sets of catheters for pumping by catheter pumps P are provided. Specifically, a first conduit 4a for feeding the cultivation liquid 5 from the tank 3 to the supply passage 12 and a second conduit 4b for feeding the excess liquid 6 from the cultivation container 1 to the tank 3 are provided. Furthermore, air valves 4c and 4d are provided on the upstream side of the first conduit 4a from the conduit pump P and on the upstream side of the second conduit 4b from the conduit pump P, respectively.

[0053] In the plant cultivation apparatus of the third embodiment, the cultivation liquid 5 can be sent from the tank 3 to the supply channel 12 and the excess liquid 6 can be sent from the cultivation container 1 to the tank 3 without switching the rotation direction of the catheter pump P. Specifically, if the duct pump P is driven with the air valve 4c closed...

Abstract

A plant culturing device capable of distributing a culturing liquid to the roughly entire part of a culture medium in a short operation time without separately installing a supply passage and a supply pump communicating with a tank. A pump (P) switchable between a state in which the stored liquid (5) is fed to a culturing container and a state in which an excess liquid (6) and an aerating air (7) are allowed to flow into the tank is installed in a communication passage (4) allowing the culturing container (1) for plant (A) to communicate with the tank (3) for the culturing liquid (2). The device also comprises a switching part (16) allowing the communication passage to communicate with the culturing container on the bottom side, allowing a supply passage (12) capable of supplying the stored liquid from the opening part side for planting to the culturing container to be branched and connected to the communication passage, and selectively switchable between a state in which the supply passage is allowed to communicate with the tank and a state in which the communication passage is allowed to communicate with the tank. The pump is installed on the upstream side of the branched connection part of the supply passage in the culturing liquid supply direction.

Description

technical field [0001] The present invention relates to a plant cultivating device, which is provided with a pump in a connecting channel connecting a cultivating container capable of cultivating plants and a tank capable of storing the above-mentioned plant cultivating liquid. state, and a state in which the remaining liquid in the cultivation liquid supplied to the cultivation container and the ventilation air bubbled in the storage liquid flow into the tank. Background technique [0002] The advantage of the above-mentioned plant cultivating device is that, by making the pump provided in the connection channel connecting the cultivating container and the tank, in the state of supplying the cultivating liquid to the cultivating container and making the remaining liquid in the cultivating liquid supplied to the cultivating container flow into By switching between the states in the tank, the remaining liquid can be actively flowed into the tank without additionally providing...
