【Example】

 The present invention will be described below with reference to an embodiment shown in the drawings.

First, the overall outline of the hydroponic cultivation apparatus (hereinafter, simply referred to as an apparatus) 1 of this embodiment will be described.

In FIG. 3, (a) is a plan view of the device 1, and (b) is a side view.

The device 1 has five pedestals 2a, 3a, 4a, 5a, 6a and cultivation beds 2b, 3b, 4b, 5b, 6b placed on each of these pedestals.

The pedestals 2a and the like and the cultivation beds 2b and the like are formed in the same shape, and the pedestals 2a and the like are arranged in the direction of the straight line P at regular intervals W.

Hereinafter, the direction of the straight line P will be referred to as the arrangement direction P.

On the other hand, the width dimension of the cultivating beds 2b and the like in the arrangement direction P is the width of the gantry 2a and the like supporting the cultivating beds 2b and the like plus a dimension approximately corresponding to the interval W. Since the interval W is smaller than the width of the gantry 2a or the like, even if the cultivating bed 2b or the like is moved to one side of the gantry 2a or the like as shown in FIG. Is located above the gantry 2a and the like.

A stopper (not shown) is provided on each of the cultivating beds 2b and the like so that the cultivating beds 2b and the like are prevented from being excessively pushed from the end surface of the gantry 2a and the like. The cultivation bed 2b and the like are prevented from falling.

At the bottom of these cultivation beds 2b and the like, which is adjacent to other cultivation beds, an edge portion is provided with a connecting means 7 (described later) that enables mutual connection / separation.

The arrangement of the hook 8 and the pin 9 of the connecting means 7 in this device 1 is shown in FIG. 3 (a), in which the triangle indicates the hook 8 and the circle indicates the pin 9. It is something to display.

The pedestal 4a of the apparatus 1 configured as described above is provided with the driving means 11 detailed in FIGS. 1 and 2, and the driving means 11 is mounted on the pedestal 4a. The cultivation bed 4b is displaced in the arrangement direction P.

The drive means 11 is not provided on the other mounts 2a, 3a, 5a, 6a other than this mount 4a.

The gantry constituting the device 1 as described above is formed as follows.

The case of the gantry 4a will be described in detail below with reference to FIGS.

A frame 12 is, for example, a frame welded steel pipe. On the upper surface of the frame 12, a plurality of roller conveyors 14 each having, for example, six guide rollers 13 arranged inside the channel material are installed at appropriate intervals.

The roller conveyor 14 corresponds to the guiding means in the present invention, and the roller conveyor 14 is installed in the arrangement direction P of the mounts.

Therefore, the cultivation bed 4b placed on the pedestal 4a can be moved only in the P direction by the roller conveyors 14.

The parts related to the frame 12 and the roller conveyor 14 are exactly the same as the mounts 2a, 3a, 5a and 6a.

Further, in this embodiment, since the cultivation bed 4b is formed in a long and narrow rectangular shape, the movement and movement of the cultivation bed 4b reduce the bending and twisting that occur in the cultivation bed 4b and the pedestal 4a, and the movement of the cultivation bed 4b is reduced. For smoothness, the driving means 11 installed only on the gantry 4a includes a link mechanism 18 and the like, which will be described later, at the center and both sides of the gantry 4a in the direction orthogonal to the arrangement direction P. There are a total of three installed.

Since the link mechanisms 18 and the like have the same structure, only one of them is described in the drawings and the following description, and the others are omitted.

That is, the drive means 11 has an electric motor 16 as a drive source, a screw shaft 17, and a link mechanism 18, which are installed inside the frame 12.

The electric motor 16 and the screw shaft 17 are installed so as to serve also as the link mechanisms 18 on both sides.

The electric motor 16 is reversible and has a drive sprocket 21 mounted on its output shaft. Since the electric motor 16 also serves as the three link mechanisms 18 of the gantry 4a as described above, it is installed in the central portion of the gantry 4a.

The screw shaft 17 is disposed generally between both ends of the gantry 4 a in a direction orthogonal to the arrangement direction P so as to serve also as the three link mechanisms 18.

A driven sprocket 22 is fixed to a portion near the center of the screw shaft 17, and a chain 23 is wound around the drive sprocket 21 of the electric motor 16 and the driven sprocket 22. The screw shaft 17 is rotationally driven.

On the screw shaft 17, a drive screw portion 26 including a set of a right-hand screw portion 24 and a left-hand screw portion 25 is formed for each link mechanism 18, each of which is configured as follows. ing.

That is, female screw members 27 and 28 that are screwed into the screw portions 24 and 25 are attached to the right screw portion 24 and the left screw portion 25 of the drive screw portion 26 for each link mechanism 18. Therefore, in this embodiment, the pitches of the screw portions 24 and 25 are the same.

Therefore, with respect to the constant rotational displacement of the electric motor 16, the female screw members 27 and 28 are displaced toward and away from each other at equal distances along the screw shaft 17.

The ends of the input link 18a of the link mechanism 18 are rotatably connected to the female screw members 27 and 28, respectively.

The link mechanism 18 is a four-bar link in which the lengths of the left and right links are set to be equal, and the pair of left and right input links 18a are rotatably pivoted so as to intersect each other in an X shape. One end of each of the pair of input links 18a is pivotally supported, and the other end is pivotally supported at the other end.

A connecting bar 31 is installed at the tip of the link mechanism 18, and the upper end of the connecting bar 31 is connected to the bottom edge of the cultivation bed 4b.

Therefore, the connecting bar 31 is driven forward and backward in a direction orthogonal to the screw shaft 17, that is, in the arrangement direction P by the approaching and moving-away movements of the female screw members 27, 28, and thereby the cultivation bed 4b. Are moved in the arrangement direction P on the gantry 4a.

As described above, in this embodiment, the linking bar 31 is used to connect the cultivation bed 4b, which is an object to be driven, and the screw shaft 17 with each other by using the connecting bar 31 to extend and contract. Is set parallel to the moving direction of the cultivation bed 4b.

This means that if the link mechanism 18 is connected in an inclined state, a rotational torque acts on the female screw members 27 and 28 due to the component force of the expansion and contraction driving force of the link mechanism 18, This is because it leads to damage to the screw shaft 17 and the like.

Further, in this embodiment, the stroke length of the link mechanism 18 is set to be substantially the same as the passage width W, and in the maximum extension state, the cultivation bed 4b closes the passage on one side, On the contrary, in the minimum contracted state, the cultivation bed 4b operates so as to block the passage on the other side.

The female screw members 27, 28 are formed with guide protrusions 32 for preventing twisting due to the rotational driving of the screw shaft 18. The front end portions of the guide protrusions 32 are formed. A roller 33 is rotatably attached to the upper and lower sides.

A guide rail 34 made of a channel material is installed in parallel with the screw shaft 17 behind the screw shaft 17 at a position within the moving range of the female screw members 27 and 28. Inside the rail 34, the tip portion of the guide protrusion 32 having the roller 33 is accommodated, and together with the sliding movement of the female screw members 27 and 28 by the screw shaft 17, the screw shafts of the female screw members 27 and 28 are moved. We are trying to prevent companionship by 17.

The cultivation bed 4b placed on such a pedestal 4a is driven forward and backward in the array direction P via the connecting bar 31 by the operation of the female screw members 27 and 28 as described above. The connecting means 7 between the cultivating bed 4b and the cultivating bed 5b adjacent to the cultivating bed 4b are as shown in FIG. 4, for example.

Each connecting means 7 shown in FIG. 3 has the same structure as described below.

That is, the pin 9 is provided so as to project downward at the bottom edge of the bottom of the cultivation bed 4b on the pedestal 4a on the side of the connecting bar 31.

Then, on the bottom surface of the bottom of the cultivation bed 5b adjacent to the cultivation bed 4b, at the edge of the cultivation bed 4b on the pin 9 side, a hook is provided via a pivot 36 projecting downward. 8 is rotatably provided in a plane parallel to the bottom surface of the cultivation bed 5b.

The hook 8 can be engaged with and disengaged from the pin 9 of the cultivation bed 4b when the cultivation bed 4b is adjacent to the cultivation bed 5b.

A coil spring 37 having one end fixed to the bottom is connected to the hook 8 and is elastically urged, and the hook 8 is in the engaged state shown by the solid line in FIG. 4 and the storage shown by the phantom line in FIG. Dead points are set in place between the states.

Therefore, when the hook 8 is located closer to the storage side than the dead point around the pivot 36, the tension of the coil spring 37 acts on the hook 8 so as to be in the retracted state, and the engagement side from the dead point. When it is positioned at, the tension of the coil spring 37 acts on the hook 8 so that the hook 8 is engaged.

An operating rope 38 is attached to the hook 8. The operation rope 38 is wound around pulleys 39 (only one is shown) rotatably installed at four corners of the bottom surface of the cultivating bed 5b formed in a rectangular shape in a top view. Is formed in a ring shape over the entire circumference of.

When the hook 8 is operated by pulling the operation rope 38 and the dead point is passed around the pivot 36, the hook 8 is brought into the engaged state or the retracted state by the tension of the coil spring 37. , That state is maintained.

In this embodiment, since the operation rope 38 is formed in a ring shape over the entire circumference of the cultivation bed 5b as described above, the hook 8 can be operated / disengaged from any side of the cultivation bed 5b. The three hooks 8 shown in FIG. 3A are connected by the operation rope 38 so that they can be operated simultaneously.

In this embodiment, the connecting means 7 is provided, but the invention of the present application can also be implemented by using a known connecting fitting.

The device 1 thus configured is used as follows.

In the case where a passage is formed between the cultivation beds 5b and 6b from the state shown in FIG. 3, the operation rope 38 of the cultivation bed 6b is operated to bring the hook 8 into the retracted state. Similarly, the cultivation beds 5b and 4b are brought into a connected state.

After that, the driving means 11 of the gantry 4a is operated to move the cultivation bed 4b to the left in FIG.

By this movement of the cultivation bed 4b, the cultivation bed 5b is pulled by the hook 8 and moves together. Further, regardless of whether the hook 8 is engaged or disengaged, the cultivating bed 3b is pushed by the cultivating bed 4b to move, and a predetermined passage having an interval W is formed between the cultivating beds 5b and 6b.

In this way, along with the movement of the cultivation bed 4b, the other cultivation beds 2b, 3b, 5b, 6b can also be freely moved through the connecting means 7 to form a passage space beside the desired cultivation bed. Can be formed.

Therefore, it is not necessary to always secure a passage space beside each cultivation bed, and it is possible to reduce the passage space. Therefore, the storage space for the cultivation bed can be expanded accordingly and a larger cultivation bed can be arranged. can do.

The device 1 can be configured by adding the roller conveyor 14, the connecting means 7, and the driving means 11 to the conventional hydroponic cultivation device, and therefore, can be configured relatively easily. You can

[Effect of device]

 As explained above, according to the first aspect of the present invention, the cultivation beds on the gantry having the driving means are also moved along with the movement of the cultivation beds on the gantry. It is possible to form a passage space beside a desired cultivation bed according to necessity by connecting / disconnecting the connecting means.

Therefore, the passage space can be made smaller and the storage space for the cultivation beds can be increased accordingly, as compared with the conventional case where the passage space is always provided beside each cultivation bed, and thus the cultivation bed having a larger area can be obtained. Can be placed.

In addition to the conventional hydroponic cultivation apparatus, the hydroponic cultivation apparatus according to the present invention includes a guide means on a pedestal, a connecting means between adjacent cultivating beds, and a drive for one pedestal. Since it can be configured only by providing means, it is a relatively simple device without making the hydroponics device large-scale.
