Description

The present invention relates to the cultivation of vegetables, including a bean sprouts and radish sprouts and Mamenae buds also vegetables, and in particular about the RuHara fee seed soaking system immersing the raw seeds used for cultivation.

  Common sprout vegetables include mung bean, peas, soybeans, brilliants, etc., also called sprout, and typical ones include "sprouts", "Kaiare Daikon" and "bean seedlings". Cultivation of such bud vegetables, after washing and sterilizing the seeds of the raw material, in order to promote germination, as a pretreatment, soaked in warm water for a predetermined time (also referred to as preparation treatment), After that, it is put in a cultivation container and periodically watered to grow and cultivate.

  For example, Patent Document 1 discloses that a dipping process is performed as a pretreatment for a sprouts cultivation process. In this dipping treatment, raw material seeds are hydrated to prepare for germination (germination), or from germination to germination. Specifically, raw material seeds are put into a container, warm water is supplied into the container, and the raw material seeds are immersed in the supplied immersion water for several hours, for example, to germinate or germinate and germinate.

  When the dipping process is completed, the raw material seeds are taken out of the dipping water, or the dipping water in the container is discharged to stop the dipping of the raw material seeds. It is a method of discharging the immersion water inside. Therefore, a drain outlet is provided in the container, the immersion water is drained from the drain outlet, the immersion treatment is terminated, and the process proceeds to the cultivation process. For example, in the case of bean sprouts, a cultivation container having a large capacity of, for example, 500 kg, 1 t, or 2 t is used, and this cultivation container may be used in the immersion treatment.

In addition, these immersion treatments and cultivation processes are performed in a room that is shielded from the outside world and maintained at a temperature and humidity in order to efficiently maintain the environment necessary for germinated vegetables, and is shielded from light. Sometimes it takes place indoors.
In the case of a cultivation room used in the cultivation process, it is general that a device for supplying water such as a watering machine is provided. Usually, an operator supplies water by remote operation without entering the room.

JP 2008-283877 A

  By the way, in the immersion treatment, there is a case where this cultivation room is also used or a dedicated immersion chamber is used, but even in the immersion treatment, it is possible to perform water supply and drainage of the immersion water by remote operation without entering the room by the operator. It is requested to be. In this case, a water supply device such as a watering machine similar to that in the cultivation room can be applied for water supply, but in order to perform drainage remotely, means for enabling the drainage port to be opened and closed remotely is required. is there.

  The purpose of sprouting by soaking treatment is to promote germination and germinate uniformly, but if the soaking time is set longer in the soaking treatment, a temperature difference between the upper and lower layers of the soaking water will occur, and this germination action will occur. In order to suppress this, or if the immersion time is set to be long, the water temperature and water quality change and the optimal immersion conditions cannot be continued. May be replaced. Even when this immersion water is replaced, it is necessary to discharge and supply the immersion water in the container. To maintain the immersion environment and ensure work efficiency, the drainage port can be opened and closed remotely. A means to make it necessary.

As a means for opening and closing the drain port by remote operation in this way, an open / close valve such as an electromagnetic valve is provided at the drain port, and this valve is electrically controlled to open and close.
However, the interior of the room during immersion is divided and managed as described above, is humid, and the surroundings of the container are exposed to water during water supply. If the switchgear that has been used is applied, the durability of the device becomes an issue, which requires waterproofing to ensure durability, frequent maintenance, etc. It is difficult to ensure sufficient durability and reliability.

  Since an open / close device using electricity cannot be used, it is conceivable to manually open and close by applying a manual valve to the drain outlet. In this case, water can be supplied before the cultivation container is put into the room where the immersion treatment is performed, and the container can be taken out from the room and drained manually. Because it is partitioned and managed to maintain, the immersion water cannot be replaced indoors.

Furthermore, using dedicated containers for each of the dipping treatment and the cultivation process is costly and requires work to transfer the raw material seeds from the dipping container to the cultivation container. I want to be able to perform immersion treatment using a cultivation container.
The present invention has been invented in view of such problems, and uses a raw material seed soaking container and a drain pipe equipped in the raw material seed soaking container that can replace water in the raw material seed soaking container with a simple configuration.

In such an immersion chamber 1, an immersion process is performed.

[Drainage pipe]
Next, the drain pipe 20 attached to the container 10 will be described with reference to FIG.
The drain pipe 20 discharges the water in the container 10. The inlet end 21 connected to the drain outlet 14 of the container 10, the outlet end 23 that discharges water to the floor of the immersion chamber 1, and these And an intermediate portion 22 that is bent between the end portions 21 and 23.

The inlet end 21 is coupled to the drain port 14 via the seal joint 21A. In the case of the present embodiment, since the drain port 14 is formed in the bottom surface part 11 a of the bottom part 11, the inlet end 21 is connected to the drain port 14 with the opening facing upward.
The outlet end 23 is equipped with the opening facing downward. When the drain pipe 20 is attached to the container 10, the outlet end 23 is shaped so as to be positioned lower in the vertical direction than the vertical position of the drain outlet 14 (the vertical position of the inlet end 21). Yes.

  The intermediate portion 22 communicates between the two end portions 21 and 23. However, since the inlet end portion 21 has the opening facing upward, the intermediate portion 22 is disposed in the substantially horizontal direction directly below the inlet end portion 21 on the upstream side of the intermediate portion 22. And a horizontal pipe portion 22b extending in a substantially horizontal direction so as to extend from the first bent portion 22a to the outside of the bottom surface portion 11a. The intermediate portion 22 further includes a second bent portion 22c bent vertically upward from the horizontal tube portion 22b, a first vertical tube portion 22d extending vertically upward from the second bent portion 22c, and the first vertical tube portion. It has a third bent portion 22e that is bent 180 degrees vertically downward from 22d and a second vertical pipe portion 22f that extends vertically downward from the third bent portion 22e, and an outlet end portion 23 at the lower end of the second vertical tube portion 22f. Is provided.

The third bent portion 22e has an uppermost portion 22g that is positioned at the uppermost position in the drain pipe 20 when the drain pipe 20 is attached to the container 10.
Further, the uppermost portion 22g at this time is set higher than the reference water level when the hot water for immersion is put into the container 10 and lower than the upper edge 13 of the container 10, whereby the drain pipe 20 is placed in the container 10 When attached to the base 10 in the reference posture, the drain pipe 20 functions as a siphon structure.

  Further, the first vertical pipe portion 22d and the second vertical pipe portion 22f are adjacent to each other, and the third bent portion 22e is connected by bending these vertical pipe portions 22d and 22f by 180 degrees. That is, these vertical pipe portions 22d and 22f and the third bent portion 22e are adjacent to the side wall portion 12 of the container 10 when the drain pipe 20 is attached to the container 10, but in this embodiment, the drain pipe 20 is as far as possible. It is set so as to approach the side wall 12 of the container 10. Specifically, when the drain pipe 20 is attached to the container 10, the first vertical pipe portion 22d is in contact with or close to the container 10, and the first vertical pipe portion 22d and the second vertical pipe portion 22f are also in contact with or close to each other. .

  Therefore, as shown by a two-dot chain line in FIG. 1A, the drain pipe 20 does not come into contact with the side wall portion 12 of the other container 10 even if the other container 10 is disposed close to the container 10. For this reason, when the container 10 is accommodated in the immersion chamber 1, the drainage pipe 20 does not lower the accommodation efficiency. If the accommodation efficiency of the container 10 is not taken into consideration, the space between the first vertical pipe portion 22d and the container 10 and the space between the first vertical pipe portion 22d and the second vertical pipe portion 22f may be widened.

  The seal joint 21A has a structure such as a quick joint (coupler), for example, and can be easily attached and detached while maintaining liquid tightness. Usually, such a seal joint 21A has a structure in which a joint portion fixed to the drain port 14 side and a joint portion fixed to the inlet end portion 21 side are attached to and detached from each other. The seal joint 21A is not limited to such a quick joint, but has a structure in which screws that are screwed to each other on both the drain port 14 side and the inlet end portion 21 side are screwed together with a seal ring or the like, and both are clamped. You may use what is fastened by. In addition, the structure of the drain port 14 may apply the suitable adapter member, even if it is the conventional drain port 14 as it is.

In addition, a separate drainage port that can be manually opened and closed is provided separately from the drainage port 14 to which the drainage pipe 20 is attached at the bottom 11 of the container 10, and this another drainage port is manually opened as necessary to Ten water may be completely removed.

[Action]
Since the container 10, the drain pipe 20, and the immersion chamber 1 according to the first embodiment of the present invention are configured as described above, for example, an immersion process is performed as shown in the flowchart of FIG.
FIG. 4 is a flowchart showing the control of the water fountain machine 2 and the water fountain supply apparatus 3 by the control device 100.

First, in step S <b> 10, the raw material seed S is put into each container 10 in the preparation room 8.
Next, in step S20, these containers 10 into which the raw material seeds S have been introduced are carried into the immersion chamber 1 from the entrance door 4, and after the completion of the entry, the entrance door 4 is closed and the immersion chamber 1 is blocked from the outside. (The state where both the entrance door 4 and the exit door 5 are closed). At this time, only the raw material seed S placed on the permeable support plate 16 is put into the container 10 and no immersion water is contained.

Next, the immersion water supply process of step S30 is implemented. In this immersion water supply step, the water purifier 2 and the brine supply device 3 are operated by the control means 100 to supply immersion water into each container 10 to the immersion water level.
Here, the immersion water level is a water level set so as to be lower than the uppermost portion 22g of the drain pipe 20 and higher than the input raw material seed S. Further, the immersion water level may be set for each type of raw material seed S and the input amount.

Next, the dipping process in step S40 is performed. In this dipping process, the raw material seed S is dipped in the dipping water for a preset time in a state where the dipping water is stored up to the dipping water level in the container 10.
And if predetermined time passes, the immersion water drainage process of step S50 will be implemented. In this immersion water drainage step, the container 10 is further supplied with water to a level higher than the uppermost portion 22g, and the immersion water in the container 10 is discharged through the drainage pipe 20 according to the siphon principle.

Hereinafter, the amount of water dripping in the immersion treatment and the change in the water level in the container 10 will be described using the time chart of the immersion treatment shown in FIG. In this example, the immersion water is replaced (immersion water replacement process) only once during the immersion process. FIG. 5 shows one container 10 by paying attention.
Here, the amount of drowning when the dredger 2 is operated and dredged (the amount of drowning per unit time determined by the discharge flow rate of the pump 3d) is constant, and the time schedule is set in advance. The traveling speed of the submerged pipe 2b of the water purifier 2 during operation is also the traveling speed during storage and the traveling speed during drainage so that the required amount of water supply can be obtained while moving on one container 10 from one end to the other end. Are preset.

First, at time t0, after the container 10 is accommodated in the immersion chamber 1, the container 10 is accommodated in a state where the entrance door 4 is closed and the immersion chamber 1 is shielded from the outside.
At the next time point t1, the flooded pipe 2b travels and starts flooding. At the time of flooding, while the flooded pipe 2b moves on one container 10, the water level in the container 10 rises substantially in proportion to the flooded amount (time t1 to time t2, immersion water supply process).

At the time point t2, the water level in the container 10 becomes the immersion water level, the submersion of the water purifier 2 into the container 10 is finished, and the immersion process is started.
The immersion water level is a water level that is lower than the uppermost portion 22 g of the drain pipe 20 and higher than the input raw material seed S, and is set as a water level suitable for the immersion treatment of the raw material seed S. Is done. In addition, this immersion water level is set for each kind of raw material seed S and the input amount.

And the state by which immersion water is stored in the container 10 continues, and the raw material seed S is immersed in immersion water (time t2-time t3).
At a time point t3 after a certain soaking time, the submerged pipe 2b of the submersible machine 2 starts submerging while running again and is supplied to the container 10 for drainage. With this water supply, the water level in the container 10 further rises and reaches the upper position above the uppermost portion 22g while the flooded pipe 2b moves on the container 10 (time t3 to time t4). Here, as shown in FIG. 5, the water supply amount for drainage is substantially half of the water supply amount for storing the immersion water, and the drain pipe 2b at the time of water supply for drainage at the time point t3 to the time point t4. Is set to approximately twice the traveling speed of the water pipe 2b at the time of water supply for storing water at time t1 to time t2. Thereby, when moving on one container 10 from one end to the other end, approximately half of the water during storage is supplied into the container 10.

When water is supplied to a position higher than the uppermost portion 22g, the immersion water in the container 10 is discharged according to the principle of siphon (time t4 to time t5). At time t5, all the immersion water is discharged from the container 10.
And at the next time t6, water supply for the water storage in the container 10 by the water sprinkler 2 is started similarly to the time t1.

From time t6 to time t7, as in time t1 to time t2, the water level in the container 10 rises due to water supply. And at the time t7, the water level in the container becomes the immersion water level similarly to the time t2.
In this manner, in the immersion process, the immersion water is replaced from time t3 to time t7.

And the state by which immersion water is stored in the container 10 continues, and the raw material seed S is immersed in immersion water (time t7-time t8).
At the time point t8, the process proceeds from the immersion process to the immersion water discharging process, and the water is sprayed in the same manner as at the time point t3, and the water spraying is stopped at the time point t9 as in the time point t4.
At time t10, all of the immersion water in the container is discharged as in time t5, and the immersion water discharging step ends.

At the time t10, the dipping process is terminated, and then the outlet door 5 is opened, the container 10 is carried out from the dipping room 1 to the preparation room 9 which is carried into the cultivation room, and the next cultivation process is started.
In addition, if the bud vegetable is a bean seedling, after the dipping treatment, the sprouting or germinated raw material seed S is sown in a tray-shaped cultivation container, and the cultivation process is performed.

In FIG. 5, the immersion time (time t2 to t3, time t7 to t8) for immersing the raw material seeds is briefly displayed, but this immersion time (time t2 to t3, time t7 to t8) is replaced with immersion water. It is a sufficiently long time with respect to time (time t3 to time t7).
Moreover, in FIG. 5, although the case where replacement | exchange of immersion water was illustrated once, you may perform the replacement | exchange process of immersion water of the time t3-time t7 arbitrary number of times.

〔effect〕
Therefore, according to the container (raw material seed soaking container) 10 and the drain pipe 20 according to the present embodiment, the uppermost portion 22g of the drain pipe 20 is set higher than the immersion water level and lower than the upper edge 13 of the container 10, Since the outlet end portion 23 is provided at a lower position than the inlet end portion 21 connected to the bottom surface portion 11a of the container 10, when the immersion water is supplied, the immersion water is stored if the water is supplied up to the immersion water level. When the immersion water is discharged, if the water is further supplied into the container 10 to make the water level higher than the uppermost portion 22g of the drain pipe 20, the drainage of the container 10 can be performed according to the siphon principle of the drain pipe 20. If the water supply is stopped at this stage, the water in the container 10 is drained to the bottom surface portion 11a thereafter.

That is, as described above, the water supply into the container 10 and the drainage from the container 10 can be performed simply by supplying and stopping the water. There is no need to provide an electrical element such as an electromagnetic valve that can be opened and closed by remote operation in the drain pipe 20, and there is no inconvenience due to moisture adhesion of the electrical element.
Moreover, in the case of this embodiment, just by setting the operation program of each part concerning drowning in the control apparatus 100 in advance, supply of immersion water (immersion water supply process) and discharge of immersion water (immersion water discharge process) are performed automatically. In addition, the immersion water replacement process (immersion water replacement process) can be performed, and the work load can be greatly reduced.

Further, the drainage port 14 provided on the bottom surface portion 11a of the container 10 and the raw material seed S put on the permeable support plate 16 placed on the stepped portion 15 are separated from each other. Even if the flow rate is increased, the raw material seed S is not damaged.
Moreover, if immersion processing is performed in the cultivation room which carries out vegetable cultivation of buds, water supply to the container 10 and the container 10 are generally made by using the water fountain machine 2, the water fountain supply device 3 and the control device 100 provided in the cultivation room. It is possible to drain from the inside. That is, it is possible to replace the immersion water without using an electrical element such as an electromagnetic valve in the drain pipe 20 or the drain port 14 using existing equipment.

Further, even in the closed dipping chamber 1, the raw material seed S can be dipped by supplying water up to the dipping water level, and can be drained from the container 10 by supplying water to a higher position than the uppermost portion 22g. Water supply and drainage into the inside 10 can be carried out simply by supplying and stopping water by the flooded water supply device 3.
Further, since the drain pipe 20 can be connected to a well-known container drain, water can be supplied into the container 10 and drained from the container 10 using an existing container. In this case, it is not necessary to provide an electrical element, and the reliability of supply and discharge of immersion water can be ensured.

  In the dipping step, if the dipping into the dipping water for germination or germination of the raw material seed S and the replacement of the dipping water are performed intermittently, the dipping water can be replaced while dipping the raw material seed. By replacing this immersion water, the temperature difference generated between the upper and lower layers of the immersion water during immersion can be reduced, germination or germination of the raw material seed S can be made uniform, and the temperature reduction of the immersion water can be reduced. The soaking treatment of the raw material seed S is promoted and the soaking time can be shortened. Therefore, the production efficiency of bud vegetables can be improved.

Moreover, if a disinfectant is added to immersion water, the raw material seed S can be germinated or germinated, and the raw material seed S can be sterilized. Since this disinfectant is considered to be less effective over time during the immersion treatment, if the immersion water to which this disinfectant is added can be replaced, the disinfectant component can be maintained, The amount and quality of the disinfectant component can be changed.
Further, the side wall portion 12 of the container 10 is slightly inclined so that the side wall portion 12 slightly expands toward the upper opening 17, and the vertical pipe portions 22d and 22f and the third bent portion 22e are close to the side wall portion. Therefore, even when the containers 10 are packed so that the upper edges 13 of the containers 10 are in contact with each other and accommodated in the immersion chamber 1, the drain pipe 20 does not interfere with the adjacent container 10, and the container 10 is efficiently used in the immersion chamber 1. It is possible to accommodate the water and to supply and drain the immersion water with a simple configuration while maintaining the production efficiency.

In addition, a preparation room (preparation space) 8 is provided on one side of the immersion room 1 adjacent to the immersion room 1, and a cultivation room [or container 10 is provided on the other side of the immersion room 1 adjacent to the immersion room 1. If the preparation room (preparation space) 9 to be carried into the cultivation room is provided, the soaking treatment of the raw material seeds and the subsequent cultivation of the bud vegetables can be carried out in a series of steps, and work efficiency can be ensured. In addition, since the region W1 from one end to the other end of the submerged nozzle of the submerged pipe 2b is set so as to be just above the width W2 of the container 10 accommodated, there is no waste without leaking out of the container 10 Can supply water. Thereby, the amount of flooding can be reduced.

[Container variants]
Hereinafter, modified examples of the container 10 of the present embodiment will be described.
Instead of the container 10 shown in FIG. 1, a container 110 shown in FIG. 3A may be used.
The container 110 includes a bottom portion 111. The bottom portion 111 includes a bottom surface portion 111a and a side surface portion 111b that rises upward from four edges of the bottom surface portion 111a.

A first drainage port 114a and a second drainage port 114b are provided on two opposing surfaces of the side surface portion 111b, respectively.
A first drain pipe 20R is connected to the first drain port 114a, and a second drain pipe 20L is connected to the second drain port 114b.
Other configurations are the same as those of the container 10.

The first drain pipe 20R and the second drain pipe 20L are connected with the inlet end portions 21R and 21L facing the drain ports 114a and 114b. For this reason, there is no portion corresponding to the first bent portion 22a of the drain pipe 20.
On the upstream side of the intermediate portions 22R and 22L of the drain pipes 20R and 20L, horizontal straight tube portions 22bR and 22bL having short straight inlet tube portions 21R and 21L toward the outside of the stepped portion 115 are provided.

A first valve 29R and a second valve 29L are interposed in the horizontal pipe portions 22bR and 22bL, respectively. These valves 29R and 29L are manual on-off valves. In other words, if either one of the valves 29R and 29L is closed and the other is opened, either of the drain pipes 20R and 20L to be used can be selected.
The uppermost part 22gR of the first drain pipe 20R and the uppermost part 22gL of the second drain pipe 20L are set differently. In the example of FIG. 3A, the uppermost part 22gR is set to be higher than the uppermost part 22gL.

In addition, you may provide the drain port 114a, 114b in the bottom face part 111a. Accordingly, the inlet end portions of the drain pipes 20L and 20R and the upstream side of the intermediate portions 22L and 22R are the same as the shapes of the inlet end portion 21 and the first bent portion 22a of the drain pipe 20 shown in FIG. Formed. Further, the other configurations of the drain pipes 20L and 20R are the same as those of the drain pipe 20.
Therefore, according to the container 110 and the drain pipes 20L and 20R, any one of the drain pipes 20R and 20L to be used can be selected by closing one of the valves 29R and 29L and opening the other.

For example, since the input amount of the raw material seed S is different, even if the immersion water level is set differently, any of the drain pipes 20R and 20L to be used can be selected, so that different immersion treatments can be handled. At this time, since the drain pipes 20R and 20L to be used can be selected without removing the drain pipes 20R and 20L, work efficiency can be secured.
Moreover, it may replace with the container 10 and may use the container 210 shown in FIG.3 (b), (c).

The container 210 includes a bottom portion 211 and a side wall portion 212 composed of four side walls.
The side wall portion 212 is a side wall that surrounds all sides of the container 210 and has an upper edge 213 that defines an upper opening 217 at the upper end thereof. In this example, the side wall 212 is slightly inclined so that the side wall 212 slightly extends toward the upper opening 217.
The bottom portion 211 includes a bottom surface portion 211a and a side surface portion 211b that stands upward from the four edge portions of the bottom surface portion 211a.

The side surface portion 211b is provided with a drain outlet 214 for discharging the water in the container 210. A drain pipe 620 is connected to the drain port 214.
The drain pipe 620 is formed of a flexible pipe such as a hose, for example. An intermediate portion 622 of the drain pipe 620 is installed in contact with or close to the side wall portion 212 of the container 210. A locking member 218 is fixed to the side wall portion 212 in order to lock the intermediate portion 622 to the side wall portion 212 so as to be movable up and down. With this locking member 218, the free end side (exit side end) of the intermediate portion 622 can be raised and lowered while in contact with or close to the side wall portion 212 of the container 210.

As another member for fixing the drain pipe 620 to the side wall 212, a first hook 219 a and a second hook 219 b are provided on the side wall 212.
These latching portions 219a and 219b are made of an elastic member and latch the bent portion 622A having the uppermost portion 622g positioned at the top in the vertical direction by this elastic force, and either one is used. That is, depending on whether the bent portion 622A is hooked on the first hook portion 219a or the second hook portion 219b, the bent portion 622A itself is displaced, and the height of the uppermost portion 622g of the drain pipe 620 can be adjusted. Become.

The length of the drain pipe 620 is set so that the height of the outlet end 623 is lower than the inlet end 621 even if the bent portion 622A is hooked on either of the hooks 219a and 219b.
Other configurations are the same as those of the container 10.
Therefore, since the middle part 622 of the drain pipe 620 is installed in contact with or close to the side wall part 212 of the container 210, space can be saved. When a plurality of containers 210 are accommodated in a room such as the immersion chamber 1, it can be efficiently accommodated.

  Moreover, since it becomes possible to adjust the uppermost part 622g of the drain pipe 620 depending on whether the bent part 622A is hooked on either the first hook part 219a or the second hook part 219b, the set immersion water level, The height of the uppermost part 622g can be easily changed and adjusted according to the water level raised for drainage.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In addition, the description which overlaps with 1st Embodiment is abbreviate | omitted.
FIG. 6 is a perspective view showing a container having a drainage pipe with a height adjusting mechanism according to a second embodiment of the present invention, and the uppermost part of the drainage pipe is arranged in the order of (a), (b) and (c). Indicates the lowered state. FIG. 7 is a perspective view showing a drain pipe according to the second embodiment of the present invention, (a) is a diagram showing the drain pipe according to the present embodiment, and (b) to (e) are modified examples thereof. FIG.
The container 210 has the same configuration as that of the modification of the first embodiment [see FIGS. 3B and 3C].

As shown in FIGS. 6A to 6C and FIG. 7A, the drainage pipe 120 has a transparent part 124 in which a part of the first vertical pipe part 122d is formed of a transparent pipe. That is, if the water level in the pipe of the drain pipe 120 is higher than the lower end of the transparent part 124 and lower than the upper end, the water level in the pipe interlocked with the water level in the container 210 can be confirmed from the outside.
The transparent portion 124 is marked with a scale, for example, an arrow mark indicating the reference position. As this reference position, for example, the immersion water level corresponds. Further, a water level such as a dangerous water level that is set as dangerous for water supply into the container 210 may be marked.

The seal joint 121A couples the drain pipe 120 to drain ports 114 and 214 provided in the bottom side walls 111b and 211b of the containers 110 and 210 as illustrated in FIGS. 3A to 3C, for example.
The seal joint 121A is coupled to a member on the drain outlets 114, 214 side (not shown). The member on the drain pipe 120 side and the member on the drain outlet side can rotate with a sense of moderation around the axis. It has become. Therefore, a tilting mechanism for tilting the intermediate portion 122 from the vertical direction to the side is constituted by a structure in which both members of the seal joint 121A are relatively rotated and fixed at an appropriate relative angle. This is configured as a height adjustment mechanism that enables adjustment of the height of the uppermost portion 122g of 122A.

FIG. 6A shows a reference posture in which the transparent pipe portion 124 of the drain pipe 120 provided in the container 210 is along the vertical direction, and the outlet end portion 123 faces vertically downward.
When the transparent tube portion 124 along the vertical direction is tilted, for example, by 45 degrees from this reference posture, as shown in FIG. 6B, the uppermost portion 122g becomes lower than when it is in the reference posture. This posture is called a special posture.

When the robot is further rotated 45 degrees from the posture of FIG. 6B, that is, when rotated 90 degrees from the reference posture, the heights of all the intermediate portions 122 and the outlet end portions 123 are increased as shown in FIG. 6C. The height of any part of the drainage pipe 120 is lower than that of the permeable support plate 16.
Other configurations are the same as those of the first embodiment.
Therefore, according to the drain pipe 120 and the container 210 of the second embodiment, since the uppermost part 122g is configured to be adjustable, it corresponds to a setting change of the immersion water level or the water level that is raised for drainage with a simple configuration. be able to.

The height of the uppermost part 122g can be adjusted by simply rotating the drain pipe 120 via the seal joint 121A, and it is possible to cope with a rapid setting change such as the immersion water level.
Since the height adjusting mechanism is a tilting mechanism, it is possible to cope with setting changes such as the immersion water level with a simple configuration.
Moreover, since the drain pipe 120 has the transparent part 124, the water level in the container 210 can be confirmed from the outside.

  Moreover, since the uppermost part 122g can be adjusted to a lower position than the permeable support plate 16, if the raw material seed S germinated or germinated is put in the container 210 used in the dipping process, the process proceeds to the next cultivation process. In the state where water sprinkled from above the container 210 flows out from the bottom of the container 210, drainage of the sprinkled water suitable for the cultivation process can be performed without accumulating water in the container 210. Further, water is not stored above the water permeable support plate 16, and water higher than the water permeable support plate 16 can be drained.

In addition, the drain pipe 120 may be equipped with the container 110. In this case, the drain pipes 120 having different heights of the uppermost part 122g are respectively equipped.

The ball joint 424 constitutes a tilting mechanism that tilts the vertical pipe portions 422d and 422f and the bent portions 422c and 422e. This tilting mechanism is a height adjusting mechanism that adjusts the height of the uppermost part 422g of the drain pipe 420 so as to be adjustable.

For example, a bellows-like seal member may be provided on the outer periphery of the ball joint 424 as indicated by a two-dot chain line.
If the intermediate part 422 downstream of the second bent part 422c is rotated 90 degrees with respect to the horizontal pipe part 422b, as shown in FIG. 6 (c), the heights of the uppermost part 422g and the outlet end part 423 become the same, The height of any part of the drain pipe 420 is lower than that of the permeable support plate 16.

The drain pipe 520 of FIG. 7 (e) is connected to the drain port 14 provided in the bottom surface part 11 a of the container 10.
The drain pipe 520 is formed so that the inner diameter of one end of the horizontal pipe section 522b is substantially equal to the outer diameter of one end of the second bent section 522c, and can be rotated and fixed. That is, this connecting structure constitutes a tilting mechanism that tilts the intermediate portion 522 downstream of the second bent portion 522c with respect to the horizontal tube portion 522b. This tilting mechanism is a height adjusting mechanism that adjusts the height of the uppermost portion 522g of the drain pipe 520.

If the intermediate part 522 is rotated 90 degrees with respect to the horizontal pipe part 522b, the heights of the uppermost part 522g and the outlet end part 523 are the same, and the height of any part of the drain pipe 520 is lower than the bottom face part 11a. .
For example, a bellows-like seal member may be provided on the outer periphery of one end of the horizontal tube portion 522b and one end of the second bent portion 522c, as indicated by a two-dot chain line.
