<Drain outlet cover member 20>
Next, the drain outlet cover member 20 (intrusion suppression member) will be described. As shown to Fig.3 (a), the drain cover member 20 has the main body cylinder part 30 and the cover member 40, and the main body cylinder part 30 is the drain port side cylinder part 31, and the water flow hole formation cylinder part. 32 and an upper cylindrical portion 33.

  The drain port side cylinder part 31 is a part inserted in the drain port 17 of the cultivation tank 1, and is comprised by the resin-made cylindrical members, for example. The outer diameter of the drain port side cylinder portion 31 is determined to be the same as or slightly smaller than the inner diameter of the drain port 17. Further, the length of the drain port side cylinder portion 31 is determined to be a length that prevents the drain port cover member 20 from falling over or falling out in a state where the drain port side cylindrical portion 31 is attached to the drain port 17.

  The water flow hole forming cylinder part 32 is a member in which a water flow hole through which the culture solution passes is formed, and is constituted by, for example, a resin-made cylindrical member. Is the outer diameter of the water passage hole forming cylinder part 32 determined to be larger than the outer diameter of the drain port side cylinder part 31, and is the inner diameter of the water hole forming cylinder part 32 the same as the outer diameter of the drain hole side cylinder part 31? Slightly smaller. And the drain port side cylinder part 31 is joined to the water hole formation cylinder part 32 in the state in which the upper end was inserted in the lower end of the water hole formation cylinder part 32. As shown in FIG. That is, the upper end portion of the drain port side cylindrical portion 31 is fitted inside the lower end portion of the water passage hole forming cylindrical portion 32. As a result, the lower surface 32 a of the water hole forming cylinder part 32 forms a stepped surface at the joint portion between the water hole forming cylinder part 32 and the drain port side cylinder part 31.

  When the drain port cover member 20 is attached to the drain port 17, the lower surface 32 a (step surface) of the water passage forming cylinder portion 32 comes into contact with the upper surface of the bottom plate 13 as shown in FIG. 4. Thereby, the position of the drain port cover member 20 in the vertical direction is determined.

  A plurality of water passage holes 34 are provided on the side surface (circumferential surface) of the water passage formation cylinder portion 32 so as to penetrate the thickness direction. This water passage hole 34 is a part for guiding the culture solution in the drainage space 11B to the drainage port 17 side, and is formed at intervals in the circumferential direction. In this embodiment, eight water passage holes 34 are formed at equal intervals at intervals of 45 degrees. In addition, the diameter of the water passage hole 34 should just ensure the required flow volume of the culture solution to the drain outlet 17, but it is preferable that it is as small as possible. This is because if the diameter of the water passage hole 34 is reduced, the roots of the climbing plant 8 are less likely to enter the water passage hole 34. Considering such circumstances, in this embodiment, the water passage hole 34 having a diameter of about 5 to 10 mm is formed.

  Further, as shown in FIG. 3B and FIG. 4, a strainer 50 is disposed inside the water passage hole forming cylinder portion 32. The strainer 50 is made of a disk-shaped mesh material having a central portion recessed from the peripheral edge. The outer diameter of the strainer 50 is determined to be the same as or slightly smaller than the inner diameter of the water passage hole forming cylinder portion 32, and is formed on the upper surface of the drain port side cylinder portion 31 positioned below the water passage hole 34. It is placed.

  The upper cylinder part 33 is a part on which the lid member 40 is covered, and is constituted by, for example, a resin-made cylindrical member having the same outer diameter and inner diameter as the drain outlet side cylinder part 31. And the upper cylinder part 33 is joined to the water hole formation cylinder part 32 in the state in which the lower end was inserted in the upper end of the water hole formation cylinder part 32. As shown in FIG. That is, the lower end portion of the upper cylindrical portion 33 is fitted inside the upper end portion of the water flow hole forming cylindrical portion 32. As a result, the upper surface 32 b of the water hole forming cylinder part 32 forms a stepped surface at the joint between the upper cylinder part 33 and the water hole forming cylinder part 32.

  The lid member 40 is configured by a cylindrical member whose ceiling portion is closed. The inner diameter of the lid member 40 is set to be slightly larger than the inner diameter of the upper cylindrical portion 33. Further, the height of the lid member 40 is determined to be higher than the length of the upper cylindrical portion 33 (specifically, the length of the portion above the upper surface 32b of the water passage forming cylindrical portion 32). For this reason, when the lid member 40 is put on the upper cylinder portion 33, the lower surface 41 of the lid member 40 comes into contact with the upper surface 32 b of the water passage hole forming cylinder portion 32 as shown in FIG. 4.

  As shown in FIG. 4, when the drain port cover member 20 is used, the water hole forming cylinder portion 32 is inserted into the drain port 17, and the lid member 40 is placed on the upper cylinder portion 33. Then, the culture solution that has flowed into the drainage space 11 </ b> B enters the drainage port cover member 20 through the water passage hole 34 of the water passage hole forming cylinder portion 32 and is guided to the drainage port 17. Here, since the strainer 50 is disposed below the water passage hole 34 inside the drain port cover member 20, even if dust smaller than the water passage hole 34 enters, the waste can be caught by the strainer 50. Can do. And even if the root 8a of the hanging plant 8 extends from below the pot 18 and reaches the drain cover member 20 through the water inlet 15a of the partition wall 15, the small diameter water holes 34 are spaced apart. Therefore, the root 8a is unlikely to enter the inside of the drain port cover member 20. Thus, the malfunction that the root 8a of the climbing plant 8 penetrates into the water passage hole 34 can be easily suppressed. And even if it is a plant which has a thick root like the vine plant of the department of Uleaceae, the malfunction can be suppressed reliably.

  Even if the root 8 a of the climbing plant 8 has entered the water hole 34, the drain cover member 20 is attached to the drain 17 in a detachable state. For this reason, the root 8a can be easily treated by removing the drain port cover member 20 from the drain port 17. For example, by lifting the drain cover member 20 in a state where the root 8a has entered the water passage 34 and removing it from the drain 17 and cutting the tip portion of the root 8a with scissors or the like and removing it from the water passage 34, The root 8a can be processed.

  Further, since the upper tubular portion 33 is covered with the lid member 40, even if the vine of the climbing plant 8 extends and reaches the drain cover member 20, the vine penetrates into the drain cover member 20. This can be suppressed.

<Regarding the first modification of the drain outlet cover member 20>
