Description

The present invention relates to a planter for wall greening. In particular, it is a wall greening planter arranged vertically and horizontally along the wall surface of the building in order to shield the building from direct sunlight, and suppresses clogging of drain holes caused by the growth of roots of plants planted in the planter. The present invention relates to the structure of a planter for wall greening, which can quickly recover the culture solution supplied to the potting soil of the planter and can smoothly circulate the culture solution.

In recent years, wall greening in which plants are planted on the outer wall of a building has been attracting attention as it helps to alleviate the heat island phenomenon and save energy. In addition, by arranging plants along the outer wall of the building, it is possible to improve the landscape of urban areas where there are few natural trees. For such wall greening, for example, a unit-type wall greening method in which planters planted with plants are arranged vertically and horizontally along the wall of a building has been proposed or implemented.

The unit-type wall greening method is characterized in that it can cover the walls of buildings other than vines, and there are relatively few restrictions on the types of plants to be planted in planters and the like. In addition, the unit-type wall surface greening method has the advantage that it is easy to automate irrigation and the like, and even if some plants are depleted, the landscape can be maintained by replacing the planter in which the plants were grown.

Compared to soil cultivation in which plants are cultivated using planters, so-called potted plants, in which plants are cultivated in natural land or fertilized fields, most of them use artificial potting soil, so soil diseases can be reduced. , Is said.

In elevated cultivation, shelves are built higher than the ground, and crops such as strawberries are cultivated on the shelves. Elevated cultivation has the advantage that the work load can be reduced because the crops can be harvested at waist height. Further, since the planter for elevated cultivation uses artificial potting soil such as peat moss or rice husk, there is an advantage that the concern about soil disease can be reduced.

On the other hand, in elevated cultivation, when the roots of crops such as strawberries grow, there is a concern that the drainage channel provided at the bottom of the planter will be clogged and become a hotbed of bacteria that cause diseases. For this reason, an elevated cultivation device that suppresses clogging of the drainage channel is disclosed (see, for example, Patent Document 1).

Further, there is disclosed a planter for growing fruit vegetables which can reduce the cost of the planter, prevent root rot due to water retention, increase the root activity, and reuse the wastewater containing organic matter (see, for example, Patent Document 2). ).

Next, the operation and effect of the planter 10 will be described while supplementing the configuration of the wall surface greening device 100 according to the embodiment. Referring to FIG. 5 or FIG. 7, the upper horizontal drainage pipe 2 is closed at one end and connected to the vertical drainage pipe 21 at the other end. Similarly, one end side of the lower horizontal drainage pipe 2 is closed, and the other end side is connected to the vertical drainage pipe 21. It is preferable that the horizontal drainage pipe 2 is arranged so as to be slightly downwardly inclined toward the vertical drainage pipe 21.

With reference to FIG. 5 or FIG. 7, a pump (not shown) is installed at the extension destination of the vertical drainage pipe 21, and the surplus culture solution is collected and the culture solution is supplied to the sprinkler pipe 11p. , The culture solution can be circulated in a plurality of planter bodies 1.

Referring to FIGS. 2 to 4, the plurality of drain holes 12d penetrate vertically from the bottom surface of the drain groove 11d. A set of inclined surfaces 11s and 12s is formed on the bottom surface of the planter main body 1. These inclined surfaces 11s and 12s are inclined downward toward the drainage ditch 11d. As a result, the excess culture solution can be quickly flowed down into the drainage ditch 11d, and the excess culture solution can be quickly recovered from the plurality of drainage holes 12d.

Referring to FIG. 3, since the drainage mat 15 is laid on the bottom surface of the planter main body 1 without blocking the drainage groove 11d, the roots of the plants planted in the culture soil Sf are the drainage layer. Even if it passes through Ld and extends to the bottom surface side, it is blocked by the drainage mat 15 and does not block the drainage groove 11d, so that clogging of the drainage hole 12d due to the growth of plant roots can be suppressed.

Referring to FIGS. 1 to 4, the planter 10 according to the embodiment has a drainage groove 11d extending along the longitudinal direction of the bottom surface of the planter main body 1 and a set of inclined surfaces 11s and 12s inclined downward toward the drainage groove 11d. Is provided on the bottom surface of the planter body 1, a drainage mat 15 is laid on the bottom surface of the planter body 1, and a plurality of drainage holes 12d penetrating the drainage groove 11d are directly connected to the horizontal drainage pipe 2 arranged at the bottom of the planter body 1. As a result, clogging of the drainage hole 12d can be suppressed, and the culture solution can be smoothly circulated without foreign matter being mixed in the horizontal drainage pipe 2.

With reference to FIG. 4, the planter 10 according to the embodiment can climb a vine on the greening fence 5 by planting a vine on the planter main body 1. By covering the greening fence 5 with vines, a so-called green curtain can be formed, so that the wall surface We of the building can be shielded from direct sunlight.

The wall surface greening planter according to the present invention has the following effects.
(1) Excess culture solution can quickly flow down into the drain.
(2) It is possible to suppress the clogging of drainage holes caused by the growth of roots of plants.
(3) The culture solution can be circulated smoothly without foreign matter getting mixed in the horizontal drainage pipe.
(4) By planting vines on the planter body, the wall surface We of the building can be shielded from direct sunlight.
