  Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of already well-known matters and repeated descriptions for substantially the same configuration may be omitted. This is to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.

  The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

(Embodiment 1)
Hereinafter, the first embodiment will be described with reference to FIGS.

In the first embodiment, an example of growing a plant planted in a hydroponics sponge medium will be described. For plants, for example, lettuce, cabbage, large leaves, Japanese mustard spinach, leek, tomato, parsley, strawberry, hyacinth and the like can be used.
[Outline of cultivation process]
First, the cultivation process of the hydroponics plant is demonstrated using FIG.
It is sowed in the sponge medium 10a arranged on the tray. The nutrient solution is immersed in the sponge medium 10a and waits for seeds to germinate.
When seeds germinate in the sponge medium 10a, the sponge medium 10b is replanted in the cultivation plate 21 (for example, 64 holes) (Step 1). The cultivation plate 21 is in a temporary planting state, and plants (seedlings) are grown to a certain size.

  And if a seedling becomes a certain size, it will replant to the cultivation plate 22 (for example, 36 holes) (Step2). The replanted seedling is further grown, and the grown plant (sponge medium 10d) is harvested.

[Details of each cultivation process]
In the first embodiment, as shown in FIG. 2, a urethane sponge is used for the sponge culture medium 10 for hydroponics. The sponge medium 10 is cut so that it can be separated into, for example, approximately four squares of 25 mm square. For example, the sponge medium 10 can be separated into 300 pieces. Each piece of sponge medium 10a has a cross cut near the center.

  The seed is planted in the cross cut. By allowing the sponge medium 10a to suck the nutrient solution, it is possible to germinate and grow seeds on the sponge (sponge medium 10b).

  The sponge medium 10b of the grown plant (seedling) is separated into pieces from the sponge medium 10 and replanted on the cultivation plate 21 (temporary planting). In the first embodiment, each piece is manually separated, but may be automated.

  As shown in FIG. 3, the cultivation plate 21 has 64 holes 21A for growth. Although the example of 64 cultivation plates 21 was shown, it may be 49 pieces or 36 pieces. The cultivation plate 21 can be made of polystyrene. The growth holes 21 </ b> A are formed in a substantially cylindrical shape in the thickness direction of the cultivation plate 21. The thickness of the cultivation plate 21 is substantially uniform with the thickness of the sponge medium.

  In the present embodiment, the sponge medium 10b is transplanted manually. However, the sponge medium 10b may be transplanted using a transplantation difference support device described later. When transplanted, a temporary planting state as shown in FIG. 4 is obtained.

  Since the seedlings grown in the temporary planting state have a smaller space when grown on the cultivation plate 21, they are transplanted to the cultivation plate 22 (32 holes) having the same area and fewer holes than the cultivation plate 21 (64 holes). Is done.

  When taking out the sponge culture medium 10c containing the seedling from the cultivation plate 21, as shown in FIG. 5, an extrusion pin 31 and a holding arm 32 provided as a part of the transplantation support device are used. The push pin 31 is realized by three pins so as not to damage the roots of the seedling. The three pins are arranged away from the center so as not to push out near the center of the bottom surface of the sponge medium 10c. The sponge medium 10 c is pushed out from the cultivation plate 21 by being pushed out by the pushing pin 31. The pushed sponge medium 10c is grasped by the grasping arm 32, completely taken out from the hole 21A of the cultivation plate 21, and moved onto the hole 22A of the cultivation plate 22. The push pin 31 and the grip arm 32 are made of stainless steel. This is because the plant is cultivated by hydroponics, so that the push pin 31 and the gripping arm 32 are less rusted. The push pin 31 and the grip arm 32 are connected to a control unit 60 described later via a drive unit. The control unit 60 drives the push pin 31 and the grip arm 32 by controlling the drive unit.

  As shown in FIG. 6, the cultivation plate 22 has 36 holes 22 </ b> A for growth. Although the example of 36 cultivation plates 22 was shown, 25 or 16 may be sufficient. That is, it is sufficient that the number of holes is smaller than that of the cultivation plate 21. The cultivation plate 22 can be made of polystyrene. The growing hole 22 </ b> A is formed in a substantially cylindrical shape in the thickness direction of the cultivation plate 22. The thickness of the cultivation plate 22 is substantially uniform with the thickness of the sponge medium.

  Hereinafter, the configuration of a part of the transplantation support device used for transplanting the cultivation plate 22 will be described with reference to FIG.

  The support members 41, 42, 43, and 44 are fixed to the transplantation support device. In the transplant support device, the receiving member 44 is fixed to the upper surface of the support member 42. The cultivation plate 22 is positioned and arranged above the receiving member 44. Although the method of positioning is not specifically limited, It is good to comprise with the receiving member 44 (left of FIG. 7) which regulates the side surface of the cultivation plate 22. FIG. In the present embodiment, the cultivation plate 22 has a 6 × 6 36-hole configuration. Therefore, in order to efficiently transplant the cultivation plate 22, in the present embodiment, as shown in FIG. 8, six transplant support configurations for each piece are provided in parallel between the receiving members 44. I have to.

  Here, the receiving member 44 supports and cultivates the cultivation plate 22, so that when the transplantation is performed by moving the cultivation plate 22 by a machine or the like in the direction perpendicular to the direction in which the cultivation member 22 is sandwiched, More efficient seedling transplantation can be performed.

  Returning to the description of FIG. 7, the first drive member 45 is disposed on the support member 41. The first drive member 45 can be realized by a motor or the like. The first drive member 45 moves the first moving member 46 in the vertical direction. The first moving member is made of stainless steel to prevent rust. The 1st moving member 46 moves the cylinder part 46a which can insert the 2nd moving member 48 which uses the stopper pin 48a as a part to an up-down direction. Here, a reverse umbrella portion 50 is provided on the upper portion of the first moving member 46. When the first moving member 46 is moved up and down, the reverse umbrella portion 50 moves as the first moving member 46 moves. The reverse umbrella part 50 is biased in the opening direction, and opens the umbrella when the restriction of the opening / closing restriction part 49 is released, and closes the umbrella when the restriction of the opening / closing restriction part 49 becomes strong. Here, the opening / closing regulating portion 49 is disposed on the upper portion of the support member 42 and is configured in a substantially cylindrical shape. The first drive member 45 is electrically connected to the control unit 60 realized by a CPU, a memory, and the like. The controller 60 controls driving of the first drive member 45.

  The second drive member 47 is disposed below the support member 42. The second drive member 47 can be realized by a motor or the like. The second driving member 47 moves the second moving member 48 in the vertical direction. The second moving member 48 is made of stainless steel and has a stopper pin 48a. The stopper pin 48a is movable independently of the cylindrical portion 46a. The second drive member 47 is electrically connected to the control unit 60 realized by a CPU, a memory, and the like. The controller 60 controls driving of the second drive member 47.

  The reverse umbrella portion 50 is made of vinyl, and is formed by rounding a member formed in a substantially sector shape with a central angle of 45 ° to 70 ° and bonding the end portions of the sector shape. The reverse umbrella part 50 is configured by adjusting the thickness of vinyl. This is because if the vinyl is too thick, it will catch the roots of the seedlings when the umbrella is closed, while if the vinyl is too thin, the vinyl will be caught by the water and the umbrella will open. This is because there is a possibility that it cannot be opened. The vinyl thickness is preferably in the range of 0.05 mm to 0.2 mm.

  Here, the reason why vinyl is urged outward will be described. Generally, vinyl having a certain thickness has elasticity, so when a fan-shaped vinyl is rolled up, a force to open outward is generated. Therefore, the reverse umbrella part 50 is configured to open outward when the opening / closing restriction part 49 is removed from the urging force generated by rounding the vinyl.

  The operation flow of the porting support configuration configured as described above will be described with reference to FIG.

  First, the transplantation support device is in an initial state with the cultivation plate 22 disposed on the receiving member 44. The initial state is the arrangement shown in FIG.

  The first driving member 45 and the second driving member 47 are driven to raise the first moving member 46 and the second moving member 48. At this time, with the movement of the first drive member 45, the umbrella of the reverse umbrella portion 50 passes through the hole 22A of the cultivation plate 22 and is opened (umbrella opening). Further, the stopper pin 48 a of the second moving member 48 is moved to the vicinity of the bottom surface of the cultivation plate 22. In this state, the grip arm 32 (connected to the control unit 60) shown in FIG. 6 is driven to move the sponge medium 10c containing the seedling to the upper part of the hole 22A. The gripping arm 32 arranges the sponge medium 10c on the upper part of the opened reverse umbrella part 50 (vegetable insertion).

  Thereafter, the first driving member 45 is driven, and the first moving member 46 is lowered. As the first moving member 46 moves, the reverse umbrella 50 is closed. Here, the reverse umbrella part 50 is substantially conical. Therefore, even if the sponge culture medium 10c is a substantially quadrangular prism, when the sponge medium 10c is pulled into the hole 22A, the sponge medium 10c can be pulled closer to the substantially cylinder and can be transplanted by a simpler method.

  Then, when the reverse umbrella unit 50 further pulls in the sponge medium 10c, the pull-in of the sponge medium 10c is restricted by the stopper pin 48a. That is, it is reduced that the sponge culture medium 10c is drawn too much with respect to the cultivation plate 22. Here, if the thickness of the vinyl constituting the reverse umbrella portion 50 is too thick, the sponge medium 10c may be drawn too much and the roots of the seedlings may be damaged. On the other hand, if the vinyl is too thin, it may not be able to be pulled in sufficiently. Therefore, it is better to configure the reverse umbrella part 50 after adjusting to a more preferable thickness.

  By configuring the reverse umbrella portion in this manner, transplanting can be performed by a simpler method by enveloping and pulling the root of the seedling.

Moreover, it is also possible to combine each component demonstrated in the said Embodiment 1, and it can also be set as a new embodiment.

  The present disclosure is applicable to a transplant support device that can be used for transplanting plant seedlings and the like.
