In addition, at least one coupling protrusion 136 protrudes within the coupling groove 135 and is fitted into the coupling groove 115 of the unit bed 110 described above.

At this time, the coupling protrusion 136 may be a pair of structures spaced apart vertically like the coupling protrusion 136 of the connection part 120 described above.

A coupling groove 136a is formed at the center of the coupling protrusion 136, so that coupling can be easily achieved when inserted into the unit bed 110, and a strong coupling can be maintained.

A drain hole 137 is provided on a part of the lower surface of the base plate 131 . The drain hole 137 is formed in a direct downward direction.

A water level control nozzle 138 is coupled to the drain hole 137.

The water level control nozzle 138 is capable of adjusting the height of the nutrient solution accommodated in the bed 100, and the nutrient solution supplied to the height of the level control nozzle 138 or higher is passed through the inner hole of the level control nozzle 138 to the outside. It is discharged.

Nutrient solution at an appropriate level may be supplied according to the type of plant planted on the cultivation board 200 or the length of the root by the water level control nozzle 138 .

In addition, the water level control nozzle 138 is drained at a position higher than the bottom surface of the bed 100, so that rapid drainage of the nutrient solution can be prevented, and bubbles can be generated or the nutrient solution can be prevented from scattering during drainage.

The height of the water level control nozzle 138 is lower than the height of the seating surface 133 of the side cap 130.

As such, the bed 100 of the present invention can be formed by simply assembling a plurality of unit beds 110 using the connecting portion 120. In the case of using an integral bed as in the prior art or welding a unit bed, the assembly property can be greatly improved.

In addition, the bed 100 of the present invention is very easy to separate or additionally mount the unit bed 110 as needed, so that the length of the bed 100 can be easily expanded or reduced as needed.

This is a feature that cannot be expected in conventional beds manufactured by integral or welding methods.

On the top of the bed 100, the cultivation board 200 on which plants are planted is seated.

One of the features of the present invention is to mount the redistribution plate 200 through one side in the width direction of the bed 100 (for example, direction A in FIG. 1), or to take out the mounted redistribution plate 200 can

In this way, by specifying the mounting position of the cultivation plate 200, independent cultivation devices defined by the plurality of frames 500 can be placed closer together, and thus space utilization can be increased.

It can also reduce footprint and increase work efficiency.

The cultivation plate 200 is a unit cultivation plate connected to each other.

6 and 7 are perspective views of the unit cultivation plate 210, respectively.

The unit cultivation plate 210 includes a unit cultivation board body 211 in which a planting hole 212 is formed, a coupling protrusion 220 located on the front side of the unit cultivation board body 211 with respect to the moving direction, and a coupling projection ( 220) and a moving member 240 positioned on the lower surface of the unit plate body 211 and movable along the bed 100.

8 is an exemplary view of combining two unit cultivation plates 210.

As such, in the unit rearing plate 210 of the present invention, the coupling protrusions 220 or coupling grooves 230 may be coupled to the coupling grooves 230 or coupling protrusions 220 of other cultivation plates.

In addition, it can be linearly moved along the bed 100 in a state connected to each other by the moving member 240.

Accordingly, the unit rearing plates 210 located on the entire length of the long bed 100 can be mounted by pushing the unit rearing plates 210 together in a direction A in FIG. 1 .

Conversely, even when the cultivation plate 200 is taken out to harvest plants, the entire cultivation plate 200 can be easily taken out from the same position by separating the unit cultivation plates 210 from each other while pulling the cultivation plate 200.

When the movable member 240 is in contact with a part of the bed 100 and a force is transmitted by an operator or a robot, the unit plate 210 and the coupling structure of the unit plate 210 are formed along the direction of the force It serves to facilitate movement.

The surfaces to which the movable member 240 is in contact are the seating portion 113 of the unit bed 110, the seating surface 123 of the connection unit 120, and the seating surface 133 of the side cap 130.

Both the seating portion 113 and the seating surfaces 123 and 133 are planes parallel to the ground, and thus the unit cultivation plates 210 can be moved while the moving member 240 rolls without any resistance.

Another feature of using the seating portion 113 and the seating surfaces 123 and 133 is that the rear plate 200 has a structure covering the upper portion of the seating portion 113 and the seating surfaces 123 and 133. Therefore, it is possible to prevent external light (LED light as a light source) from being directly irradiated to the nutrient solution accommodated in the space inside the seating part 113.

That is, it is possible to prevent the occurrence of green algae by preventing exposure of the nutrient solution to a light source, making maintenance and management very easy.

Although not shown in the drawing, the LED light source is installed on the lower frame 500 of the bed 100. As a light source, the LED may emit blue light with a wavelength of 400 nm to 500 nm and red light with a wavelength of 640 nm to 700 nm, which can help plants photosynthesize.

The LED light source has the advantage of providing light of a wavelength band that can help the growth of plants compared to general lighting, but has a disadvantage in that it generates relatively much heat.

In the present invention, the LED light source is installed on the lower frame 500 of the bed 100 to prevent heat from directly affecting plant cultivation.

In such a coupled state, the separation coupling portion 243 is coupled to the fixing portion 247 to stably support the wheel 241 in a rotatable state.

The shape of the separation coupling portion 243 includes coupling protrusions 243b protruding from both sides of one side of the main body 243a, and has a block structure with an upper surface of a 'c' shape.

Each of the two separate coupling parts 243 includes a coupling protrusion 244 protruding from a surface facing each other, and the coupling protrusion 244 is engaged with the coupling protrusions 248 of the fixing parts 247, 247 and the separation coupling part 243 are fixed.

In such a coupled state, the operator can easily separate the separating/coupling part 243 from the fixing part 247 and replace the wheel 241 without using a separate tool.

The main body 243a has a hole 246 into which one of the rotating shafts 242 protruding from one side of the circular surface of the wheel 241 is inserted, and when the separation coupling part 243 is coupled to the fixing part 247 The wheel 241 may be fixed in a stable rotatable state.

In addition, a protruding support part 245 is provided on the surface of the main body 243a facing the wheel 241 .

The protruding support part 245 is coupled between the pair of fixing parts 247, and prevents the gap between the fixing parts 247 from narrowing so that the coupling between the coupling protrusions 248 and 244 can be maintained. .

As described above, since the movable member 240 applied to the present invention can easily replace the wheel 241 without using a separate tool, the convenience of replacing the worn wheel can be improved.

As mentioned above, in the present invention, for the configuration of the rear panel 200, the entire rear panel 200 can be combined by pushing in one direction while fitting and coupling the unit rear panels 210 to each other at a predetermined position.

In addition, when harvesting, on the contrary, the unit cultivation plates 210 may be pulled at the same location and harvested separately from each other.
