  In recent years, the size of hydroponics beds has been increasing, and beds having a length of 500 to 1000 mm, a width of 300 to 500 mm, and a depth of about 200 to 400 mm have been used. When the bed is enlarged, the volume for storing the cultivation liquid is naturally increased, and the weight of the bed when hydroponically cultivating exceeds 20 kg. In hydroponic cultivation, it is necessary to move a large number of beds arranged on an appropriate support during cultivation in accordance with the growth of the plant or the surrounding environment. However, the conventionally used hydroponics bed has only a flat surface on the outer side surface of the peripheral side wall, or a step portion with a shallow depth, and has a weight exceeding 20 kg. It is difficult to move the bed from place A to place B during hydroponics, which is a heavy work burden for the operator.

  An object of the present invention is to eliminate the above disadvantages in hydroponics currently being performed. Specifically, even if the bed is heavy, the operator can easily move the place by hand. An object is to provide a hydroponics bed that can be made.

  The bed for hydroponics according to the present invention is a rectangular bed in a plan view used in hydroponics, and is an inverted U that functions as a grip when the hand is held on the outer side surface of the peripheral side wall. An appropriate number of character-like cut portions are formed.

  In the hydroponics bed according to the present invention, since an appropriate number of inverted U-shaped cut portions functioning as a gripping portion or a handle when the bed is held by hand on the outer side surface of the peripheral side wall, By putting a hand or fingertip into the cut portion, the hydroponics bed can be easily lifted. Even when an appropriate device is used for lifting or transporting the bed, the bed can be transported and moved easily and safely by inserting the tip of the working arm of the device into the cut portion. Thereby, the work burden on the operator is reduced, and the workability of hydroponics is greatly improved.

  Hydroponics is a method of cultivation with a large number of hydroponics beds placed on a flat support base, and by cultivating by arranging the beds in multiple stages using appropriate support ridges. There is a case to do. In the latter cultivation mode, in general, a bed having a shape in which a concave groove serving as an engaging portion of a bed supporting bed is formed over the entire length of the peripheral side wall. In this type of bed, the outer wall of the groove is usually thin, and when the bed is lifted with a hand (fingertip) placed on the lower edge of the outer wall, the bed If is heavy, the outer wall may be damaged.

  In order to cope with this, in one aspect of the hydroponics bed according to the present invention, the first two side walls facing each other of the rectangular bed in the plan view are engaged with a supporting reed supporting the bed. A concave groove serving as a joining portion is formed, and the inverted U-shaped cut portion is formed by cutting out an outer wall of the concave groove.

  In the hydroponics bed of this aspect, since the inverted U-shaped cut portion is formed by cutting out the outer wall of the concave groove, an operator can put a fingertip on the reverse U-shaped cut portion. When inserting and lifting the bed, the outer wall of the groove will not be broken or damaged.

  In the hydroponics bed of the aspect in which the concave groove is formed, the inverted U-shaped cut portion may be formed also on the second opposing side walls where the concave groove is not formed. In this aspect, since the bed can be lifted appropriately using the inverted U-shaped cut portions formed on the two orthogonal side walls, the degree of freedom in lifting the bed is increased, and the working efficiency is improved. In this form of hydroponics bed, when the bed is rectangular in plan view, the groove is formed on the side wall on the long side. As a result, the posture when the bed is engaged and supported by the supporting reed is stable.

  In the present invention, the hydroponics bed can be made of a conventionally known material, but is preferably made of a foamed resin because it is lightweight and has good workability. Moreover, the method of hydroponics using the hydroponics bed by this invention is arbitrary, and it can use suitably for the conventionally well-known various cultivation methods as described in the said patent documents 1-3. .

  By using the hydroponics bed according to the present invention, even if the bed is heavy, the operator can easily and stably place it by hand without causing breakage or damage to the bed itself. You will be able to move. Thereby, the cultivation efficiency of hydroponics is also improved.

(A) is a perspective view which shows the one aspect | mode of the bed for hydroponics by this invention, (b) is sectional drawing which follows the bb line of (a), (c) is the cc line of (a). FIG. The figure for demonstrating the use condition of the bed for hydroponics shown in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a hydroponics bed according to the present invention. As shown to Fig.1 (a), the bed 1 is a box-shaped thing which opened upwards, and has comprised the rectangle by planar view. That is, the bed 1 is composed of the first two side walls 2 and 2 that are opposed to each other, the second two side walls 3 and 3 that are opposed to each other and are shorter than the side wall 2, and the bottom plate 4. The In the space a surrounded by the first side walls 2, 2, the second side walls 3, 3 and the bottom plate 4, liquid fertilizer (cultivation liquid) that is a nutrient moisture necessary for plant growth is supplied, and appropriate means (not shown) The root of a plant (not shown) supported on the space a grows in the space a, and the root grows by absorbing the fertilizer.

  In the bed 1, the upper portions of the first two side walls 2, 2 are thickened portions 2 a, 2 a that are thick on the outside, and the upper portions of the second two side walls 3, 3 are the same. Thus, it is set as the thick parts 3a and 3a which became thick outside. And the recessed part 5 and 5 are formed in the level | step-difference part which is a lower end of the thick parts 2a and 2a over the full length of the longitudinal direction, The thickness of the outer walls 6 and 6 of this recessed groove 5 and 5 is thickness. It is thinner than the thicknesses of the thick portions 2a and 2a.

  The outer walls 6 and 6 of the concave grooves 5 and 5 are formed with notches 7 having a required width and depth at three locations, that is, a central portion in the longitudinal direction and two positions symmetrical from the central portion. As shown in FIG. 1 (b), the top surface of the notch 7 reaches the position near the top surface of the groove 5. The notch 7 and the top surface portion of the concave groove 5 facing the notch 7 constitute an “inverted U-shaped notch” 8 according to the present invention. That is, in the bed 1 shown in FIG. 1, three inverted U-shaped cut portions 8 are formed by cutting out a part of the outer wall 6 of the concave groove 5 at three locations. The top surface of the portion 8 has a lateral width s which is the sum of the thickness of the outer wall 6 of the groove 5 and the thickness of the top surface portion of the groove 5.

  Although not essential, in the bed 1 shown in FIG. 1, the required width and depth are also cut at the substantially central portion in the lateral width direction of the lower end step portion of the second two side walls 3 and 3. A notch 9 is formed, and the depth of the top surface 10 of the notch 9 reaches the substantially central portion in the thickness direction of the thick portion 3a. The region formed by the notch 9 and the top surface 10 also constitutes the “inverted U-shaped cut portion” 11 referred to in the present invention.

  In the present invention, the size and shape of the space a of the bed 1 may be arbitrary and are not particularly limited. What is necessary is just to determine so that it may be suitable for hydroponics to go. In the illustrated bed, the inner surface of the bottom plate 4 of the bed 1 is an inclined surface in consideration of drainage, and an appropriate number of drain ports 12 are formed at the center. Although not shown, an appropriate opening / closing stopper is attached to the drain port 12.

  An example of the usage state of the bed 1 is shown in FIG. Here, supporting buns 20, 20 for supporting the bed 1 are laid sideways, and the above-mentioned supporting two ridges 20, 20 are provided with the first two side walls 2 having a long length opposite to each other, An appropriate number of beds 1 are arranged so that the concave grooves 5 and 5 formed in 2 are engaged (only one is shown in FIG. 2). In this state, liquid manure (cultivation liquid) is circulated and supplied into the space a, and hydroponics of the plant is performed. When the location of the bed 1 needs to be moved, the operator inserts the hand (fingertip) into the above-described inverted U-shaped cutout portion 8 that functions as a gripping portion and lifts it slightly. As a result, a gap is formed between the top surface of the inverted U-shaped cut portion 8 and the supporting recumbent ridge 20, so that a hand (fingertip) is further inserted into the gap. As described above, the top surface of each inverted U-shaped cut portion 8 has a width s which is the sum of the thickness of the outer wall 6 of the groove 5 and the thickness of the top surface of the groove 5 and is wide. Therefore, the lifting work of the bed 1 by the operator is facilitated, and the bed 1 can be reliably prevented from being damaged by its own weight during the lifting. When each of the inverted U-shaped cut portions 8 is not provided, when the bed 1 is lifted, the operator lifts the outer wall 6 of the groove 5 directly from below, but the outer wall portion 6 is thin. It is easy to break.

  In the illustrated bed 1, an inverted U-shaped cut portion 11 that functions as a gripping portion is formed at substantially the center of the lower end step portion of the thick portions 3 a and 3 a of the second two side walls 3 and 3. The depth of the top surface 10 reaches the substantially central portion in the thickness direction of the thick portion 3a. Since the operator can also lift the bed 1 using the inverted U-shaped cut portion 11, the moving operation of the bed 1 is further facilitated. Alternatively, hydroponics can be performed by placing the bed 1 on a flat surface. Even in this case, the operator can lift and move the bed by using both or any one of the inverted U-shaped cut portions 8 and 11 that function as a gripping portion.

  Although not shown, even if the bed does not have the concave grooves 5 and 5 in the stepped portions in the first two side walls 2 and 2 that face each other, when the bed is held on the outer side surface of the peripheral side wall by hand. It is extremely effective to form the inverted U-shaped cut 8 or 11 having an appropriate width and depth that functions as a gripping portion. By forming the inverted U-shaped notch 8 or 11, the operator can easily lift the bed in a stable posture, and even when the bed is tilted during movement, the position of the hand or fingertip is large. Since it is possible to avoid shifting, it becomes easier to return the bed to its original horizontal position.
