JP-A-11-178454 Japanese Patent Laid-Open No. 10-309131

  In the plant cultivation container mentioned above, the plant is generally managed for every container. For example, when a plant in a container is infected with a disease such as mosaic disease or yellowing, it is necessary to lower the container from the rack so as not to infect plants in other containers. However, in any of the containers disclosed in any of the above-mentioned patent documents, it is necessary to pull out the temperature adjustment pipe from the side surface of the container in advance when the container is lowered from the rack. Moreover, when placing a container in which another plant is planted in the vacant space, it is necessary to insert a temperature adjustment pipe from the side of the container later, which is also a complicated operation. In particular, when a plurality of containers are arranged, the pipe length becomes long, so it is extremely difficult to insert and remove the pipe.

  In addition, all containers are made of expanded polystyrene. However, since the pipe hole to be undercut is formed, the structure of the mold becomes complicated, leading to an increase in the cost of the mold. Furthermore, in the container shown in Patent Document 1, since the convex portion is formed of expanded polystyrene having heat insulating properties, heat exchange between the temperature adjusting pipe and the soil is hindered, and efficient. The temperature of the cultivation soil could not be adjusted.

  The present invention has been made in order to solve the above-mentioned problems, and by making it easy to insert and remove the temperature adjustment pipe, it is possible to eliminate the labor required for replacing the container, and the thermal efficiency of the temperature adjustment pipe is high. An object is to provide an inexpensive plant cultivation container.

  In order to achieve the above object, the invention of claim 1 is a plant cultivation container, wherein the bottom wall is divided from one end edge to the opposite edge, and the water sprayed in the container is discharged. A drainage groove to be discharged, and a pipe insertion groove formed on both side walls substantially orthogonal to the drainage groove, communicating with the drainage groove, and for inserting a temperature adjusting pipe for adjusting the temperature of the soil filled in the container. Prepare.

  The invention according to claim 2 is the plant cultivation container according to claim 1, wherein the bottom wall is partially provided from one end edge to the opposite end and is inserted into the pipe insertion groove. The guide has a reinforcing guide part that joins both sides of the bottom wall divided by the drainage groove and reinforces the bottom wall while guiding the adjustment pipe so as to straddle the adjustment pipe.

  According to a third aspect of the present invention, in the plant cultivation container according to the first or second aspect, an inclined surface is formed on the inner surface side of the bottom surface so as to descend toward the drainage groove.

  According to a fourth aspect of the present invention, in the plant cultivation container according to any one of the first to third aspects, the temperature adjusting pipe has a forward path through which hot water or cold water circulates and is inserted into the pipe insertion groove, and an upper part of the container. A recess for mounting the return path of the temperature adjusting pipe, and a recess for mounting a watering pipe for spraying water into the container. Is formed.

  According to a fifth aspect of the present invention, the plant cultivation container according to any one of the first to fourth aspects further includes a water-permeable root-proof sheet laid so as to cover the inner surface of the container and the temperature adjusting pipe.

  According to the invention of claim 1, since the drainage groove provided in the bottom wall and the pipe insertion groove provided in the side wall communicate with each other, the container is adjusted while aligning the temperature adjustment pipe and the drainage groove. The temperature adjusting pipe can be inserted and removed from the bottom side of the container simply by placing or lifting the container, and the container can be easily replaced. In addition, since the pipe insertion groove communicates with the drainage groove provided on the bottom wall, it is possible to form the pipe insertion groove even with a mold having a simple configuration without a slide core or the like, thereby reducing the cost of the container. Is possible.

  According to the invention of claim 2, since the bottom wall is reinforced by the reinforcing guide portion, the strength of the container lowered by the drainage groove can be compensated. Therefore, for example, even when the container is formed of a material having a relatively low strength such as expanded polystyrene, the container can withstand the load of the soil. Further, in the portion where the reinforcing guide portion is not provided, heat exchange can be performed between the temperature adjusting pipe and the cultivating soil, so that good thermal efficiency can be obtained.

  According to invention of Claim 3, since the water in a container flows along a slope and flows into a drainage groove, it becomes possible to drain efficiently and the water content in a container can be maintained optimally.

  According to the invention of claim 4, the temperature of the soil in the container can be easily optimized by the hot water or the cold water circulating through the temperature adjusting pipe. Moreover, since the recessed part is formed in the upper end of a side wall, the return path of a temperature control pipe and the positioning and mounting of a watering pipe can be performed now easily.

  According to the invention of claim 5, since the water-permeable root-proof sheet allows moisture in the container to permeate, the moisture in the container can be optimally managed, and the root of the plant is formed on the wall constituting the container. Is prevented from entering, so that the container can be used repeatedly. Furthermore, when a plant is infected with a disease, the plant and the soil can be taken out from the container body in a state of being wrapped in a water-permeable root-proof sheet, so that the burden on the operator is reduced.

  A plant cultivation apparatus according to the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a plant cultivation apparatus. The plant cultivation apparatus includes a plant cultivation container (hereinafter referred to as a container) 1 that accommodates plants together with cultivation soil, a temperature adjustment pipe 2 for adjusting the temperature of the cultivation soil S filled in the container 1, and the inner surface of the container. A water-permeable root-preventing sheet 3 laid on the inside of the container 1, a water spray pipe 4 for spraying water inside the container 1, a rack 5 for supporting the container 1 at a predetermined height, and the like.

  The container 1 is a bottomed rectangular container having an open upper surface constituted by a bottom wall 10, an end wall 11, and a side wall 12, and drainage for discharging water sprayed on the container 1 to the bottom wall 10. The groove 13 is formed in the end wall 11 and a pipe insertion groove 17 for inserting the temperature adjusting pipe 2 is formed therein.

  The temperature adjusting pipe 2 performs heat exchange with the cultivating soil S, and adjusts the temperature of the cultivating soil S to an optimum temperature for plant cultivation. Therefore, hot water is circulated in the winter season and cold water is circulated in the summer season as needed from the forward path 2a to the return path 2b. The forward path 2a of the temperature adjusting pipe 2 passes through the pipe insertion groove 17 of the end wall 11 of the container 1 substantially vertically, and hot water or cold water is flowed in the direction of the arrow D1. Heat is exchanged between them. The return path 2b of the temperature adjusting pipe 2 is placed on the upper end of the end wall 11, and warm water or cold water circulated through the forward path 2a is returned to flow in the direction of the arrow D2 along the return path 2b.

  The water-permeable root sheet 3 is laid so as to cover the inner surface of the container 1 and the outer surface of the temperature adjusting pipe 2, and is sandwiched by semicylindrical stoppers 7 attached to the upper end of the side wall 12. The water-permeable root-preventing sheet 3 has water permeability and allows the water soaked in the soil S to permeate and be discharged to the outside of the container 1. Since the expanded polystyrene constituting the container 1 has a fine gap at the interface between the particles due to the structure, there is a possibility that the root of the plant enters from the gap and causes a decrease in the strength of the container 1. In this embodiment, since the water-permeable root-preventing sheet 3 is interposed between the soil S and the container 1, it is possible to prevent the root from entering the container 1. In addition, although the material of the water-permeable root prevention sheet 3 is not specifically limited, In this embodiment, the resin-type material (for example, polypropylene) which has water permeability, water resistance, and corrosion resistance is used.

  The watering pipe 4 is a pipe for supplying water and liquid fertilizer to the cultivation soil S, and holes for spraying water and the like are arranged at appropriate intervals. The sprinkling pipe 4 is placed in a recess 20 formed at the upper end of the end wall 11.

  The rack 5 includes a column pipe 5a bent in a U-shape, a beam pipe 5b for supporting the load of the container 1, and the like. The container 1 is supported by the rack 5 at a predetermined height position, so that it is not necessary for the worker to bend and the burden on the worker is reduced. On the bottom surface of the container 1, a recess 14 corresponding to the pipe 5 b is formed in the longitudinal direction of the container 1. A plurality of containers 1 are placed side by side on the rack 5 so that the pipe 5b and the recess 14 are engaged.

  2 to 5 show the structure of the container 1. The bottom wall 10 of the container 1 guides the drainage groove 13 for discharging the water sprayed inside the container 1, the recess 14 that engages with the pipe 5 b of the rack 5, and the forward path 2 a of the temperature adjustment pipe 2. However, it has a horseshoe-shaped reinforcing guide part 15 for reinforcing the bottom wall 10. The drainage groove 13 is formed over the entire length of the container 1 so as to divide the bottom wall 10 into approximately two equal parts. The reinforcing guide portion 15 is formed so as to protrude toward the inner surface side (upper surface side) of the bottom wall 10, and is guided by straddling the forward path 2 a of the temperature adjustment pipe 2 while being separated by the drain groove 13. The bottom wall 10 is reinforced by joining both sides. The reinforcing guide portion 15 is not formed over the entire length of the container 1 but is partially provided as necessary to increase the strength of the container 1. A pipe insertion groove 18 that communicates with the drainage groove 13 is formed at a substantially central portion of the reinforcement guide portion 15, and the pipe insertion groove 17 of the end wall 11 and the pipe insertion groove 18 of the reinforcement guide portion 15 are arranged in a container. 1 are formed so as to substantially overlap in a side view as viewed from the longitudinal direction.

  In addition, a slope 16 is formed on the inner surface side of the bottom wall 10 to descend toward the drainage groove 13. Thus, the water that has reached the inner bottom surface efficiently flows into the drainage groove 13 along the slope 16. On the other hand, on the outer surface side (lower surface side) of the bottom wall 10, a meat stealing portion is formed as necessary in addition to the concave portion 14 described above.

  The end wall 11 substantially orthogonal to the drainage groove 13 mounts a pipe insertion groove 17 through which the forward path 2 a of the temperature adjustment pipe 2 is inserted, a recess 19 for mounting the return path 2 b of the temperature adjustment pipe 2, and the water spray pipe 4. And a recess 20 for placement. The pipe insertion groove 17 is formed so as to communicate with the drainage groove 13 from the lower end edge of the end wall 11 to the center portion. The recess 19 and the recess 20 are formed at the upper end of the end wall 11.

  Further, a semi-cylindrical stopper 7 (see FIG. 6) for sandwiching the vicinity of the edge of the water-permeable root-preventing sheet 3 folded along the side wall 12 is provided on the side wall 12 substantially parallel to the drainage groove 13. Installed. The outer corners of the upper end of the side wall 12 are rounded so that the stopper 7 can be easily attached.

  FIG. 6 shows the container 1 and the temperature adjustment pipe 2 in use. In the cross section shown in the figure (the cross section taken along the line BB in FIG. 3), there is no reinforcing guide portion 15 around the temperature adjustment pipe 2. Heat is exchanged between At this time, since the thickness of the water-permeable root-preventing sheet 3 interposed between the temperature adjustment pipe 2 and the cultivation soil S is thin, heat exchange between the temperature adjustment pipe 2 and the cultivation soil S is not hindered. Therefore, the thermal efficiency at the time of temperature adjustment by the temperature adjustment pipe 2 can be increased.

  Also, in the unlikely event that a plant is infected with a disease, the upward path 2a of the temperature adjusting pipe 2 is scraped off the soil S separated by the water-permeable root-preventing sheet 3 just by lifting the container 1 upward. After that, since the container 1 is discharged from the drain groove 13 to the outside of the container 1, it is not necessary to pull out the temperature adjustment pipe 2 in the longitudinal direction in order to lower the container 1 from the rack 5, and the burden on the operator can be reduced.

  As described above, according to the container 1 of the present embodiment, the drainage groove 13 provided in the bottom wall 10 and the pipe insertion grooves 17 and 18 provided in the side wall 11 and the reinforcing guide portion 15 communicate with each other. Therefore, the temperature adjusting pipe 2 can be inserted / removed from the bottom side of the container 1 only by placing the container 1 on the rack 5 or lifting it while aligning the temperature adjusting pipe 2 and the drainage groove 13. The replacement work of the container 1 becomes easy. In addition, since the pipe insertion grooves 17 and 18 communicate with the drainage groove 13 provided in the bottom wall 10, the pipe insertion grooves 17 and 18 can be formed even with a mold having a simple configuration. Cost reduction is possible.

  Further, since the bottom wall 10 is reinforced by the reinforcing guide portion 15, the strength of the container 1 lowered by the drainage groove 13 can be compensated. Therefore, for example, even when the container 1 is formed of a material having a relatively low strength such as expanded polystyrene, it can withstand the load of the soil S. Moreover, since heat exchange is possible between the temperature adjusting pipe 2 and the soil S in a portion where the reinforcing guide portion 15 is not provided, good thermal efficiency can be obtained. As a result, for example, cultivation of straw and the like, which has been conventionally difficult in cold regions such as Hokkaido, can be easily performed.

  Moreover, since the water inside the container 1 flows along the inclination to the drain groove 13, the water can be efficiently drained, and the water content inside the container 1 can be optimally maintained. Moreover, the temperature of the soil S inside the container 1 can be easily optimized by hot water or cold water circulating through the temperature adjustment pipe 2. Moreover, since the recessed parts 19 and 20 are formed in the upper end of the end wall 11, the return path 2b of the temperature control pipe 2 and the water sprinkling pipe 4 can be positioned and placed easily. Moreover, since the water-permeable root prevention sheet 3 permeate | transmits the water | moisture content inside the container 1, the water | moisture content inside the container 1 can be managed optimally. Further, since the sheet 3 prevents the roots of the plant from entering the bottom wall 10, the end wall 11, the side wall 12, the reinforcing guide portion 15 and the like constituting the container 1, the container 1 can be used repeatedly. . Furthermore, when a plant is infected with a disease, the plant and the soil S can be taken out from the container 1 in a state of being wrapped in the water-permeable root-proof sheet 3, so that the burden on the operator is reduced.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, the drainage groove 13 is most preferably provided along the longitudinal direction of the container 1, but may be provided along a direction orthogonal to the longitudinal direction. In this case, the pipe insertion groove 17 is formed on the long side surface of the container 1. In addition, a configuration in which a plurality of drain grooves 13 and a plurality of pipe insertion grooves 17 are provided so as to correspond to a plurality of temperature adjustment pipes 2 may be employed. The material of the container 1 is most preferably a foamed resin such as foamed polystyrene that is lightweight and excellent in heat insulation, but is not limited thereto, and other synthetic resins may be used.
