DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nutrient solution recovery device for receiving a nutrient solution that falls from a through hole at the bottom of a planter or the like. The present invention relates to a technique for easily forming a nutrient solution collecting device at low cost even when the length of the nutrient solution collecting device is long.

[0002]

2. Description of the Related Art Conventionally, in greenhouse cultivation of plants,
Horticulture using many planters and flower pots is performed. The nutrient solution (including fertilizer, water, etc.) of the plant to be cultivated is supplied to a planter or a flowerpot. Normal,
In order to prevent the nutrient solution from collecting too much in the soil in the planter or the flower pot, the through-hole is provided at the bottom of the planter or the flower pot. Fall from the hole. Since the falling nutrient solution causes environmental pollution in the house or the like, a device for collecting the falling nutrient solution is provided.

FIG. 6 shows an example of the conventional nutrient solution recovery device. In FIG. 6, the upper surface 73 of the planter 70 is open. The soil 75 is arranged in the planter 70, and the plant 76 is planted on the soil 75. Supporting device 90
The horizontal rails 91 and 92 of the planter 70
Support. Posts (93, 94, 95, 96, etc.) support the cross beams 91, 92. Also, the reinforcing members 97, 98
Connect the columns 93 and 94, and the columns 95 and 96, respectively.

FIG. 7 shows a use state of the conventional example shown in FIG. 7, a through hole 72 for discharging an excess nutrient solution 82 in the soil 75 (see FIG. 6) is formed in the bottom 71 of the planter 70. Since the excess nutrient solution 82 falls from the through hole 72, an inexpensive soft waterproof sheet 81 is disposed below the through hole 72 in order to collect the falling nutrient solution 82 easily and at low cost. ing. As shown in FIG. 6, the edge of the waterproof sheet 81 is fixed so as to be sandwiched between the flange 74 and the horizontal rails 91 and 92.

[0005]

As shown in FIG. 7, a waterproof sheet 81 stores a nutrient solution 82 dropped from a through hole 72. Reference numeral 83 denotes a liquid surface of the nutrient solution 82. In this case, since the waterproof sheet 81 does not have rigidity and elasticity, the waterproof sheet 81 bends downward as indicated by a two-dot chain line due to the weight of the nutrient solution 82. For this reason, the nutrient solution 82 does not easily flow on the waterproof sheet 81, so that there is a problem that the recovery of the nutrient solution 82 becomes difficult. Further, when the length of the waterproof sheet 81 in the left-right direction in the drawing is increased, it becomes more difficult to collect the nutrient solution 82. If a gutter such as a synthetic resin molded product is used, the nutrient solution 82 can be easily collected. However, since the gutter is significantly more expensive than the waterproof sheet 81, there is a problem that the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to reduce the deformation of a nutrient solution recovery device when receiving a nutrient solution dropped from a planter, a flowerpot, or the like, An object of the present invention is to make it possible to easily and inexpensively form a nutrient solution collecting device that can easily collect a nutrient solution even when the length of the collecting device is long.

The holding makes it easy to make the elastic sheet into the gutter shape. further,
Since the sheet is elastic, the trough-shaped sheet is less likely to be deformed by the weight of the nutrient solution when it receives the falling nutrient solution, and the sheet is formed by the elasticity of the frame. , It is easy to maintain the gutter-like shape of the sheet.

Further, the structure of the third invention is as described in claim 3. According to the configuration of the third aspect of the present invention, in addition to the operation of the configuration of the first aspect of the present invention, the rigid sheet has a belt shape. Even when the length of the liquid recovery device is long (for example, 100 m), the nutrient solution recovery device can be easily made seamless at low cost.

Further, the structure of the fourth invention is as described in claim 4. According to the configuration of the fourth aspect of the present invention, together with the operation of the configuration of the second aspect of the present invention, the elastic sheet has a belt shape. Even when the length of the liquid recovery device is long (for example, 100 m), the nutrient solution recovery device can be easily made seamless at low cost.

Further, the structure of the fifth invention is as described in claim 5. According to the configuration of the fifth aspect of the present invention, in addition to the operation of the configuration of the first or second aspect of the present invention, since the frame is formed by processing a metal rod, the frame can be easily formed.
