Japanese Patent Laying-Open No. 2005-245264 (first page, FIG. 1) Registered Utility Model No. 3005664 (first page, FIG. 1)

The present invention can be appropriately connected and appropriately lengthened so that the supply and discharge of nutrient solution and water can be sucked up from under the soil, and earth and sand can flow into the discharge hole and the liquid pipe. The object of the present invention is to provide a planter for isolated floor cultivation that smoothly feeds and discharges nutrient solution and water without clogging.
In addition, when nutrient solution or water is supplied from above the cultivated object, the soil often rebounds and adheres to the leaves of the cultivated object. The cultivated material may be infected with the virus by the bacteria in the soil and die. It is necessary to prevent such infection for planned cultivation.
In addition, when the nutrient solution or water is sucked up from the soil, the nutrient solution becomes old, which adversely affects the object to be cultivated. Therefore, it is necessary to smoothly circulate nutrient solution and water.

In particular, in agricultural plants currently being used, the supply and distribution of nutrient solution and water are managed by computers. This is to control the supply of nutrient solution and water to adjust the degree of growth of the cultivated material and contribute to stable shipment.
In other words, using the nutrient data required for the cultivated product, grasp the nutrients supplied and discharged, and consider the degree of sunshine, etc. to supply and discharge the necessary nutrients and water as needed. It is necessary to strive.
Thereby, the natural unreasonable phenomenon by the conventional bad weather can be reduced significantly, and a to-be-cultivated thing can be grown stably.
In addition, in order to accurately manage the planter, a planter that prevents the outflow from the discharge hole such as earth and sand to prevent clogging of the liquid pipe and smoothly supplies and discharges nutrient solution and water is required.

Therefore, in the present invention, a U-shaped main body having an appropriate depth and length is formed by integrally forming the bottom surface portion and the side surface portions on both sides thereof, and both ends opened in the longitudinal direction of the main body are connected to each other. It is those sequentially connecting the above body to form a discharge hole at one end of the body, to form a supply hole at a position lower than the discharge hole in the other end, the more the body The present invention is characterized in that a shielding portion for shielding the discharge hole of the adjacent main body is formed.

  Moreover, the main body is formed of a synthetic resin, the discharge hole communicates with a groove formed in the bottom surface of the bottom surface and orthogonal to the longitudinal direction, the shielding portion is an approximately L-shaped, and one wall thereof is It is preferable that a liquid passage that covers the upper part of the groove of the adjacent main body and communicates with the inside of the groove is formed between the hanging wall that follows the wall and the wall surface of the groove of the adjacent main body.

  In addition, a groove is formed in the longitudinal direction of the bottom surface, and the groove is inclined in the longitudinal direction so that the discharge hole side at the other end is higher than the supply hole side at one end. Preferably it is.

According to the first aspect of the present invention, the main bodies can be easily connected. It can be set as the cultivation field of the appropriate length used in a plant or a greenhouse by this. In addition, the nutrient solution and water can be supplied and discharged in a connected state.
The nutrient solution or water supplied from the supply hole passes below the soil and is discharged from the discharge hole. Thus, the nutrient solution and water supplied to the lower part of the soil are sucked up by a capillary phenomenon and supplied to the object to be cultivated. According to the nutrient solution supply method sucked up from below, when nutrient solution or water is supplied from above the cultivated material, bacteria can be prevented from adhering to the leaf or the like due to rebounding of the soil.
Further, by forming the shielding part in combination with the connecting means, the shielding part can prevent the discharge of soil and earth and sand, prevent clogging of the liquid pipe and the like, and can easily connect the main body with simple means. .

  According to the second aspect of the present invention, the discharge hole is formed at a position higher than the supply hole, so that the nutrient solution or water overflows to discharge. By forming a shielding part around this discharge hole, it prevents inflow of earth and sand into the discharge hole and clogs the discharge hole and liquid pipe with earth and sand while smoothly supplying and discharging nutrient solution and water. Absent.

Moreover, in the planter which supplies a nutrient solution and water by applying a fixed water pressure from a pump by the groove | channel of the bottom face part surface being formed high from the supply hole side to the discharge hole side by the invention described in claim 3 The amount of nutrient solution in the main body can be kept constant. On the other hand, when the supply of nutrient solution or water is stopped and all of the nutrient solution or water is discharged from the main body, it is possible to discharge from the supply hole at a lower position.
Therefore, it is possible to smoothly discharge the old nutrient solution or water without accumulating in the main body. It is possible to prevent the soil and the cultivated material from being adversely affected by the old nutrient solution and water.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an example of the present invention, FIG. 2 is a cross-sectional view of only the bottom surface portion of the main body, and FIGS. 3 and 4 are enlarged cross-sectional views of only the vicinity of the shielding portion showing a state where the main body 1 is connected. 5, 6, and 7 are enlarged sectional views of the main body 1, and FIG. 8 is a perspective view showing a state in which the main bodies 1 are connected.
In the present invention, the main body 1 is connected, and the nutrient solution and water are smoothly supplied and discharged to contribute to the efficiency of cultivation. The target of supply and discharge may be water as well as nutrient solution.

The necessity of the planter for isolation floor cultivation of this invention is demonstrated.
The planter of the present invention is particularly necessary when performing planned cultivation in a farm plant. The main body 1 has a groove shape and is connected to obtain a planter having an appropriate length. A supply hole 27 and a discharge hole 28 are formed in the main body 1, and the nutrient solution 43 and water can be supplied and discharged in a state where the main bodies are connected.
In addition, when a nutrient solution or water is supplied from above the object to be cultivated as in the prior art, soil bacteria adhere to the object to be cultivated due to the rebound of the soil and have an adverse effect. By supplying the nutrient solution below the soil, it is supplied to the object to be cultivated by capillary action, and the above-mentioned adverse effects can be prevented. Moreover, the use of pesticides can be refrained by preventing the adhesion of soil bacteria.
Thus, supplying the nutrient solution below the soil is a necessary supply means for stable growth of the cultivated material.

Further, in the farm plant, in particular, detailed management of supply and discharge of the nutrient solution 43 is performed. It is necessary to use the nutrient data required for the cultivated products, to understand the nutrients supplied and discharged, and to make efforts to supply and discharge the necessary nutrients and water as appropriate in consideration of the degree of sunlight. There is. In addition, for example, there are various methods such as changing the concentration of the nutrient solution according to the growth of the cultivated material or supplying the nutrient solution 43 at different times of the day. Such a cultivation method enables stable growth and shipment of the object to be cultivated.
For this purpose, a planter is required in which the nutrient solution 43 and water are supplied smoothly, the liquid pipe is not clogged with earth and sand, and the old nutrient solution can be easily discharged.
The present invention provides a planter for isolated floor cultivation with a main body 1 suitable for this.

The connecting male parts 5 and 5 are formed so as to be recessed by one step so as to be in contact with the inner surfaces of the connecting female parts 6 and 6. As a result, the connecting male portions 5 and 5 can be fitted to the connecting female portions 6 and 6, and the plurality of main bodies 1 can be sequentially connected in a state where the overhang portions 9 and 9 are flush with each other. . The user of this planter uses the main body 1 sequentially connected so as to have an appropriate length according to the size of his / her own plant or greenhouse. As shown in FIG. 8, it is necessary to provide side walls 7 and 7 at both ends of the plurality of connected main bodies to prevent the earth and sand and the object to be cultivated from collapsing.
FIG. 8 shows a state in which two main bodies 1 are connected to each other and side walls 7 and 7 are installed in two openings in the longitudinal direction. The side walls 7 are indicated by broken lines.

A shielding part 10 is formed at one end of the main body 1 where the connecting female parts 6 and 6 are located. The shield 10 has a substantially L-shaped cross section, and is formed by a vertical wall 21, a lateral wall 22, and a hanging wall 23.
As shown in FIG. 2, a vertical wall 21, a horizontal lateral wall 22 continuous with the vertical wall 21 are formed in the longitudinal direction of the main body 1, and a hanging wall 23 is formed continuously with the lateral wall 22. . The hanging wall is not formed in the vertical direction but is formed in a direction inclined about 10 degrees outward in the horizontal direction.
A portion surrounded by the vertical wall 21, the lateral wall 22, and the hanging wall 23 is open, and an open portion 24 is formed.
In addition, the hanging wall 23 is formed so as to have a height at which a soil support 25 such as a snowboard can be placed on at least the surface of the bottom surface 2 of the main body 1 when the planter is used. As shown in FIG. 4, when using the planter, the soil support 25 is placed on the surface of the bottom portion 2, and the soil 42 for cultivation is placed on the soil support 25.

A supply hole 27 is formed in the side surface portion 3 in the vicinity of the shielding part 10, and a supply groove 26 is continuously formed from the supply hole 27 in a direction orthogonal to the longitudinal direction of the main body 1. As shown in FIG. 7, the supply groove 26 is formed so as to be inclined so that the opening of the supply hole 27 becomes lower.
At one end of the main body 1 where the connecting male portion 5 is located, a discharge hole 28 is formed in the side surface portion 3, and a discharge groove 29 is continuously formed from the discharge hole 28 in a direction perpendicular to the longitudinal direction of the main body 1. Has been. As shown in FIG. 6, the discharge groove 29 is formed so as to be inclined so that the opening of the discharge hole 28 becomes lower.

Furthermore, as shown in FIG. 5, a central groove 30 is formed in the vicinity of the center of the main body 1 in the width direction in the longitudinal direction of the main body 1. The central groove is formed in the longitudinal direction of the main body 1.
Since the present embodiment is located near the center in the width direction, the central groove is used. However, it may not be near the center in the width direction if it is formed in the longitudinal direction.
As shown in FIGS. 2 to 4, the discharge hole 28 is opened at a position higher than the supply hole 27. Both holes have substantially the same diameter.
In this embodiment, the lower end of the discharge hole is higher than the lower end of the supply hole. Moreover, not only the lower end of the discharge hole 28 is higher than the lower end of the supply hole 27, but also a discharge groove 29 is formed one step higher than the surface of the bottom surface portion 2 and the central groove 30, and is partitioned by the blocking wall 31.
The lower ends of the discharge hole 28 and the supply hole 27 are both lower than the lower end of the hanging wall 23. The discharge hole 28 and the supply hole are located below the main body. This is because the soil is placed on the soil support 25 and the nutrient solution 42 and water are supplied below it.
A liquid pipe 41 is attached to both the supply hole 27 and the discharge hole 28 from the outside of the side surface portion 3. Although not shown, the liquid pipe 41 continues to the supply tank and the discharge tank, respectively, and feeds the nutrient solution 43 and water stored in the supply tank into the main body 1 through the supply hole 27 and the supply groove 26, The circulating nutrient solution 43 and water are discharged to the discharge tank through the discharge groove 29, the discharge hole 28, and the liquid pipe 41.

The central groove 30 formed on the surface of the bottom surface portion 2 is inclined so that the direction in which the discharge hole 28 is located becomes higher than the direction in which the supply hole 27 is located. As shown in FIG. 2, the slope is relatively gentle. In the embodiment, the inclination angle is set to about 2 degrees. However, the inclination angle is not limited to this.
In addition, as shown in FIG. 5, the center groove | channel 30 is formed so that it may become a groove | channel recessed one step from the bottom face part.

Since the shape of the main body 1 is such that the discharge hole 28 is higher than the supply hole 27, the nutrient solution 43 and water do not accumulate to a certain depth when the nutrient solution 43 and water are supplied from the supply hole 27. Not discharged. Moreover, since the central groove 30 is inclined so that the direction where the discharge hole 28 is located is higher than the direction where the supply hole 27 is located, a constant water pressure is applied to supply the nutrient solution 43 and water.
When the nutrient solution or water is supplied to the main body 1 and the planter is used and then the nutrient solution is completely removed from the main body 1, not only the discharge hole 28 but also the supply hole 27 can be discharged. Even when the liquid 43 or water is used, the supply groove 26, the discharge groove 29, and the central groove 30 are formed as described above so that the nutrient solution 43 and water can be easily led out from the supply hole 27. Become. Therefore, the nutrient solution 43 and water can be easily discharged from the main body 1.

As shown in FIGS. 3 and 4, the discharge groove 29 in the direction perpendicular to the longitudinal direction is formed one step higher than the surface of the bottom surface portion, and a blocking wall 31 is formed on the side thereof.
The surface of the bottom surface portion 2 of the main body 1 and the central groove 30 and the discharge groove 29 are blocked by a blocking wall 31. Therefore, the nutrient solution 43 and water pumped from the surface of the bottom surface portion 2 and the central groove 30 toward the discharge groove 29 are not discharged from the discharge groove 29 and the discharge hole 28 unless they get over the blocking wall 31 due to overflow.
As shown in FIG. 6, the blocking wall 31 is formed with unevenness continuously. In addition, it is preferable that the concave and convex portions are formed so as to be aligned with the central groove 30.

FIG. 4 shows the soil support 25 placed on the bottom surface 2 of the main body 1. And after putting the soil 42, the nutrient solution 43 and water are supplied, and the state which has arrange | positioned the to-be-cultivated object 44 is shown.

As shown in FIG. 3, when a plurality of main bodies 1 are connected, the discharge hole 28, the discharge groove 29, and the shielding wall 31 can be positioned so as to fit in the open portion 24. That is, the shield 10 covers the discharge hole 28, the discharge groove 29, and the blocking wall 31 when connected.
As a result, the nutrient solution 43 or water supplied from the supply hole 27 flows into the open portion 24 from below the drooping wall 23, overflows the blocking wall 31, flows out into the discharge groove 29, and discharge hole 28. A liquid passage 32 discharged from the liquid is formed. However, the drooping wall 23 and the soil support 25 can prevent the earth and sand from flowing into the discharge groove 28 and the discharge hole 29, and the blocking wall 31 also exhibits the effect of blocking. In FIG. 3, the liquid passage 32 through which the nutrient solution 43 and water are discharged by overflow is indicated by arrows.

An example of the use of the present invention will be described.
As shown in FIG. 8, a plurality of main bodies 1 are connected to each other as appropriate so that they can be used in a plant or a greenhouse. Side walls 7 and 7 are arranged in the longitudinal opening of the main body 1 so that earth and sand do not flow out from the end of the connected main body 1. In this way, it is possible to configure a cultivation floor having a planter having an appropriate length and having no partition in the middle. If it becomes a cultivation floor consisting of a long planter with an appropriate length without a U-shaped partition, when cultivating soil with a cultivator, it is not necessary to stop the cultivator for each partition, and it is efficient while continuously driving Good cultivation and cultivation becomes possible.

Each main body 1 of the planter has a supply hole 27 and a discharge hole 28, and a liquid pipe 41 is attached to each hole. Therefore, when supplying nutrient solution or water, a pump is supplied from the supply tank. The nutrient solution 43 and water are supplied to the supply hole 27 and the main body 1 through the liquid pipe 41 in a state where a constant water pressure is applied.
That is, a planter having an appropriate length is formed, but the nutrient solution 43 and water are supplied and discharged for each main body.

The nutrient solution 43 and water to which a constant water pressure is applied are supplied to the U-shaped main body so that the water depth is maintained at a constant depth. As described above, the nutrient solution 43 and water flow into the open portion 24 from the lower side of the hanging wall 23, overflow the blocking wall 31, flow into the discharge groove 29, and are discharged through the discharge hole 28. The discharged nutrient solution 43 and water pass through the liquid pipe 41 and are sent to the discharge tank.
By supplying and discharging the nutrient solution 43 and water for each main body 1 in this way, the distribution amount, supply time, etc. are changed based on detailed cultivation data such as the nutrient solution 43 and water and the degree of growth. It is possible to properly grow the cultivated product 44.
Further, the nutrient solution 43 can be supplied to the main body 1 by computer control.

In FIG. 4, the state which has planted the to-be-cultivated object 44 in the main body 1 is shown.
In this case, the soil support 25 is placed on the bottom surface portion 2 of the main body 1, and the soil 42 is placed thereon. The nutrient solution 43 and water are supplied from the supply hole 28 to the extent to the bottom of the soil 42 from near the upper surface of the soil support 25. The nutrient solution 43 and water supplied to the bottom of the soil 42 are sucked upward by the capillary phenomenon of the soil 42 and supplied to the cultivation object 44.
In FIG. 4, a state in which the nutrient solution 43 and water are sucked upward by capillary action and supplied to the cultivated object 44 is indicated by arrows.
In addition, by positioning the upper surface of the soil support 25 at substantially the same height as the lower end of the hanging wall 23, it is possible to prevent soil and earth and sand from flowing into the discharge hole 28 and the discharge groove 29.
