Description

  The present invention relates to an elevated bench, and more particularly to an elevated bench that forms a transferable cultivation bed and enables high cultivation in a cold region.

  Conventionally, when cultivating crops such as strawberries, a cultivation tank filled with a medium is arranged at an upper position away from the ground surface (installation surface), and the crops are cultivated near the waist of the operator. Cultivation "is carried out. This upland cultivation uses a high bench installed in a house whose room is controlled to a predetermined temperature, and is cultivated so that the crop stock comes to a high place where workers can work easily. It is. Especially, among the crops, strawberries do not extend upwards, so conventional cultivation methods (such as soil cultivation) have forced workers to be forced to bend forward, etc. The burden on the workers was heavy. In addition, strawberries are smaller in size than other vegetables and fruits, so the harvesting work is cumbersome, and it is necessary to carefully harvest one by one. It was one of. Therefore, the above-mentioned high cultivation is one of the cultivation methods having the advantage of improving the worker's working environment.

  Furthermore, the medium in which the crops are planted and cultivated is completely isolated from the soil, unlike the soil in the case of conventional soil cultivation. For this reason, it is possible to easily control the soil conditions suitable for the growth of agricultural products, and it is possible to stabilize the yield per unit area. Moreover, since the culture medium is isolated from the soil and exists independently, it is possible to quickly suppress the occurrence of soil diseases caused by pests and pathogens transmitted through the soil, and the expansion of the damage after the occurrence.

  Here, the elevated bench installed in the house needs to hold the cultivation bed including the crop to be cultivated and the culture medium above the high place for a long period of time (for example, for 6 months), and their weight. It must have sufficient strength to withstand (load). For this reason, the above-described elevated bench is particularly strongly formed to withstand heavy loads by combining a plurality of hard members such as iron square members and pipe pipes. The individual members are firmly fixed by using fastening fasteners such as bolts and nuts or by welding. Therefore, when an elevated bench is installed in a house, it is used as it is for several years (for example, 5 to 10 years) and is hardly removed from the house.

  On the other hand, as an example of a bench for elevated cultivation, an elevated cultivation facility capable of suppressing the spread of disease and appropriately supplying an optimal amount of water to crops as compared with hydroponics and hydroponics is disclosed ( For example, see Patent Document 1). Thereby, the cultivation conditions of agricultural products can be stabilized and a high yield can be obtained. These elevated cultivation facilities are provided with roller casters at the bottom of the support for supporting the cultivation tank where the crops are cultivated at a high position, and the entire elevated cultivation facility is housed when not in use. A moving means is provided for removing from the inside or moving to an arbitrary position in the house.

JP-A-10-178914

  As described above, the conventional elevated bench cannot be easily removed for several years after being fixed in the house. Here, in cold regions (including heavy snowfall areas) such as mountainous areas and high latitude areas, a large amount of snow is observed during the winter season, and after the cultivation period of crops such as strawberries is over, the house is prevented from collapsing. In addition, the work of removing the covering material (vinyl sheet) covered by the house to make only the framework has been performed. However, the elevated bench installed in the house cannot be easily removed for the reasons described above, and is often left as it is in winter. Therefore, there was a high possibility that the elevated bench would be crushed by the weight of snow during the snowfall.

  Strawberries (summer autumn strawberries) cultivated on an elevated bench are cultivated using a cool climate, and the cultivation period is carried out from May to December. Therefore, cultivation in the cold region described above was most suitable. However, since damage to the elevated bench due to snow is predicted, workers and farmers may abandon the use of the elevated bench without enjoying the beneficial effects of using the elevated bench. It was expected to take measures against this.

  On the other hand, an upland cultivation facility provided with a moving caster at the lower part of the support sometimes has problems such as a complicated structure, an increase in manufacturing cost, and an increase in the weight of the facility. Furthermore, in order to move the entire equipment from the house and remove it, there are cases where a lot of work time and personnel are required for this work. In addition, the installation surface (ground) of the house is often stretched with tubes for water supply (liquid supply) such as water and nutrient solution supplied with crops, or tubes for drainage (drainage). In some cases, a relatively large number of steps are formed. Therefore, it is necessary to get over these steps by a caster, movement is limited, and practicality may be lacking.

  Therefore, in view of the above circumstances, an object of the present invention is to provide an elevated bench that can be formed so that a cultivation tank in which crops are cultivated can be moved, and can be prevented from collapsing due to snow or the like.

  In order to solve the above-described problems, the elevated bench according to the present invention includes a “cultivation bed having a cultivation tank in which agricultural crops are cultivated, and at least a part of which is buried in the installation surface, and is directed substantially vertically from the installation surface. A cultivation bed support part configured by arranging a plurality of standing columns, and supporting the cultivation bed at an upper position spaced from the installation surface, and allowing the cultivation bed to be detached from the cultivation bed support part It is mainly composed of "connecting tool to connect".

  Here, examples of the cultivation tank include a planter for cultivation composed of a material such as polystyrene foam or plastic. Then, the cultivation of the crop is carried out by filling the space of the container-like planter with a medium and planting the seedling of the crop. At this time, a tube for supplying water, nutrient solution, etc. indispensable for the growth of crops is inserted into the culture medium, and a predetermined amount of water or the like is supplied. Further, a drainage tube or the like for drainage discharged from the culture medium is provided.

  Furthermore, the connection tool is a tool that detachably connects the cultivation bed to the column of the cultivation bed support part, and examples thereof include a buckle and a hook for locking. Thereby, in a normal use state, the cultivation bed is stably supported by the cultivation bed support part, and the cultivation bed and the crop stock can be positioned at an upper position that makes the worker's working posture good. On the other hand, by releasing the connection by the connection tool, the cultivation bed can be easily detached from the cultivation bed support part and transferred to an arbitrary position.

  Therefore, according to the elevated bench of the present invention, the cultivation bed and the cultivation bed support part are detachably coupled by the coupling tool. At this time, a load corresponding to the weight of the cultivation tank, the culture medium filled in the cultivation tank, and the crops (seedlings) planted in the culture medium was always applied to the plurality of support columns of the cultivation bed support portion vertically downward. Is in a state. Therefore, the cultivation bed connected to the connection tool is restricted from moving downward by the connection tool and is also restricted from moving in the horizontal direction. On the other hand, by performing the operation of lifting the cultivation bed (cultivation tank) from this state with a force that resists gravity due to the load, the horizontal regulation is released, and the cultivation bed can be easily separated from the column of the cultivation bed support part. Is possible.

  Thereby, the elevated bench provided in the house can transfer the cultivation bed to another place, except for the cultivation bed support part including a plurality of columns that are partly buried and fixed in the installation surface. . As a result, when the house is installed in a cold region, it is possible to prevent the house and the elevated bench from collapsing due to snow by removing surrounding covering materials and removing the cultivation bed. The removed cultivation bed is stored in a storage bed for a cultivation bed provided separately. Therefore, even when the house is installed in a heavy snowfall area, it is possible to prevent the high bench from collapsing due to snow accumulation. In this case, since the column of the cultivation bed support part partially buried in the soil is erected in the substantially vertical direction, the influence of the snow weight due to snow accumulation is small. Therefore, the state standing from the surface of soil can be maintained and there is almost no possibility of collapse.

  Furthermore, the elevated bench of the present invention has, in addition to the above configuration, “the cultivation bed further includes at least a pair of lateral support portions installed in the cultivation tank along the longitudinal direction in a substantially horizontal direction, The coupling tool is configured to have a substantially S-shape, and is connected to the bed support portion that supports the lateral support portion of the cultivation tank from below, and the bed support portion. And a hook hook formed so as to be engageable with the provided hook receiving portion.

  Therefore, according to the elevated bench of the present invention, by using the S-shaped connector, it is possible to connect the cultivation bed and the support column and maintain the cultivation bed at an upper position separated from the ground. Here, the S-shaped connector is made of a hard material such as metal, and the one that is not easily deformed by a load such as the cultivation bed described above is used. Moreover, the hook receiving part provided in a support | pillar can illustrate the pipe hole etc. which are formed in the cut surface of a tubular pipe. A locking hook having a shape corresponding to the upper part of the S-shape and having a tip bent downward is engaged with the hook receiving portion such as the pipe hole. As a result, the coupling tool is suspended from the hook receiving portion of the support column. On the other hand, the lateral support part of the cultivation bed corresponds to the lower part of the S shape connected to the locking hook, and the lateral support part of the cultivation bed is brought into contact with the inner peripheral surface of the bet support part that is bent as if the tip jumped upward. Placed. Accordingly, the lateral support portion can be supported from below by the action of the coupler whose downward movement is restricted by the engagement of the locking hook and the hook receiving portion. For this reason, it becomes possible to connect a cultivation bed to a cultivation bed support part with the coupling tool which consists of a comparatively simple structure, and to control a horizontal movement to the minimum by the dead weight of a cultivation bed etc. Further, the connection between the two can be released by a simple operation of lifting up.

  Furthermore, the elevated bench according to the present invention has, in addition to the above-described configuration, “the cultivation tank is configured to include a flexible nonwoven sheet stretched between the lateral support portions”. It doesn't matter.

  Therefore, according to the elevated bench of this invention, the sheet material which consists of a nonwoven fabric is used for the cultivation tank. This makes it possible to reduce the weight as compared to a cultivation bed mainly composed of foamed polystyrene, plastic, or the like, and allows the work to be removed from the cultivation bed support and moved to another place easily. Furthermore, since it has flexibility, it is necessary for the nonwoven fabric sheet to have sufficient strength to withstand the load on the medium and crops to be filled. For the purpose of assisting the strength of these nonwoven fabric sheets, it is also possible to use a nonwoven fabric sheet covered with a covering such as a net.

  Further, the elevated bench according to the present invention has, in addition to the above-described configuration, “a horizontal portion in which the cultivation bed support portion is close to the installation surface and is bridged and connected between the columns adjacent to each other in a substantially horizontal direction. It may be a "having".

  Therefore, according to the elevated bench of the present invention, the horizontal portion spanned between the columns is formed so as to be close to the installation surface. Therefore, when a load due to the weight of the culture medium, the crops, or the cultivation bed described above is applied to the cultivation bed support portion, the column to which the cultivation bed is connected is applied with a downward force. At this time, the column partially buried in the installation surface tends to be buried more deeply by this downward load. At this time, the horizontal portion spanned between the columns contacts the installation surface, so that the downward movement of the columns is restricted. As a result, it is possible to prevent the column from sinking to the installation surface, and to maintain the cultivation bed support portion and the initial column height.

  Furthermore, in addition to the above-described configuration, the elevated bench of the present invention may be “the crop cultivated in the cultivation tank is a strawberry”.

  Therefore, according to the elevated bench of the present invention, strawberry is adopted as a cultivated crop. This makes it possible to cultivate the “Summer Autumn Strawberry” with the above-mentioned cultivation period from May to December in a cool climate without collapsing the elevated bench even in cold regions where a large amount of snow is observed in winter. It becomes. In particular, by adopting a cultivation tank using a non-woven sheet, it can be applied to a strawberry cultivation system established as a “Gifu Prefecture method”.

  According to the elevated bench of the present invention, the cultivation bed can be detachably connected to the plurality of supports of the cultivation bed support part with a simple operation, and the elevated bench is installed in a cold region suitable for summer and autumn strawberry cultivation. can do. And during the snowy period from January to February when the strawberries were harvested, the house covering material built around the elevated bench was removed, and the cultivation bed was removed from the cultivation bed support and moved to a warehouse, etc. Therefore, it is possible to prevent the elevated bench from collapsing and damaging. Furthermore, by using a nonwoven fabric sheet for the cultivation tank, the cultivation bed can be reduced in weight, and can be easily removed from the elevated bench and moved.

  Hereinafter, an elevated bench 1 (hereinafter simply referred to as “bench 1”) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. Here, FIG. 1 is a perspective view showing a schematic configuration of the bench 1 of the present embodiment, FIG. 2 is an exploded perspective view showing a state in which the cultivation bed 2 is removed from the bench 1, and FIG. FIG. 4 is an explanatory diagram showing an example of cultivation of strawberries 6 using the bench 1, and FIG. 5 is a graph comparing medium temperature changes of the bench 1. It is.

  As shown mainly in FIGS. 1 to 4, the bench 1 of the present embodiment uses a cultivation bed 2 for cultivating strawberries 6 and a plurality of columns 4 at an upper position where the cultivation bed 2 is separated from the installation surface. It mainly comprises a cultivation bed support portion 7 for supporting, and an S-shaped hook 3 for detachably connecting the cultivation bed 2 and the cultivation bed support portion 7. Here, the S-shaped hook 3 corresponds to the connector in the present invention, and the strawberry 6 corresponds to the agricultural product in the present invention.

  More specifically, the cultivation bed 2 used in the bench 1 according to the present embodiment is provided with two cultivation tanks 8 for one cultivation bed 2 as shown in FIG. And each cultivation tank 8 is spanned between a pair of straight pipe pipes 9a and 9b having a circular cross section with a pipe diameter of 19 mm, and when the straight pipe pipes 9a and 9b are arranged in parallel to each other. A net 10 for gardening made of a net-like material and a non-woven sheet 11 stretched so as to be stacked on the net 10 stretched over. Further, in order to make the space between the straight pipes 9a and 9b constant, the straight pipes 9a and 9b are fastened and fixed by fixing pipes 12 arranged so as to be orthogonal to the upper surfaces in the vicinity of both ends and near the center. . Here, the straight pipes 9a and 9b and the fixing pipe 12 are fixed by a known fixture (for example, a bolt and a nut). Further, the fixing pipe 12 is attached so as to fix the straight pipes 9a, 9b of the two adjacent cultivation tanks 8 at the same time. As a result, the straight pipes 9a, 9b or the fixing pipes 12 at both ends are respectively gripped and lifted upward, whereby the nonwoven fabric sheet 11 laid on the net 10 hangs down and is laterally moved (arrow A in FIG. 1). Observed from the reference), the straight pipes 9a and 9b and the nonwoven fabric sheet 11 form a recess corresponding to a space filled with a coconut shell medium 13 (details will be described later).

  Here, in this embodiment, the length of the straight pipes 9a and 9b is set to about 2 m, and the length of the fixing pipe 12 is set to about 40 cm. Furthermore, the width of the cultivation tank 8 (corresponding to the length between the straight pipes 9a and 9b) is set to be about 10 cm. Furthermore, the nonwoven fabric sheet 11 used has a water permeability of about 60% in consideration of the conditions for cultivating the strawberries 6, and the width of the cultivation tank 8 is 10 cm in order to form the above-described depression. On the other hand, the thing of the width of about 25 cm is used. Here, the straight pipes 9a and 9b correspond to the lateral support portions in the present invention.

  On the other hand, as shown in FIG. 1 and the like, the cultivation bed support portion 7 is driven so that a part of the cultivation bed is buried, and the six support posts 4 are erected in a substantially vertical direction from the installation surface. The horizontal portion 14 is provided in the vicinity of the surface of the installation surface between the columns 4 adjacent to each other in the width direction of the bench 1 (on the ground). In this embodiment, concrete is laid on the installation surface. At this time, the height of the support column 4 (corresponding to a portion protruding from the installation surface) is about 70 cm, the width direction of the support column 4 is about 40 cm, which is the same as the width of the cultivation bed 2, and the length direction of the support column 4 It is set to about 1.2m. In addition, the horizontal portion 14 that is stretched orthogonally to the support column 4 is fixed by welding in the present embodiment. Thereby, even when a large load is applied to the support column 4 even if the width direction of the support column 4 is firmly stabilized, the horizontal support unit 14 is close to the installation surface. It plays a role and can prevent the column 4 from sinking into the installation surface. A pipe cutting surface 15 obtained by cutting a pipe tube is formed at the upper end of the support column 4, and a pipe hole 17 is formed inside the pipe thick portion 16. Here, the pipe hole 17 corresponds to the hook receiving portion in the present embodiment. In addition, as FIG. 1 etc. show, the part 4a of the support | pillar buried below from the installation surface is shown with the broken line.

  Furthermore, the S-shaped hook 3 is prepared for each of the six support columns 4 erected on the installation surface, and a part of the S-shaped hook 3 is inserted into the pipe hole 17 of each support column 4 to be engageable. The locking hook 18 corresponding to the side and the bet support portion 19 connected to the locking hook 18 and corresponding to the lower side of the S-shape. In the present embodiment, the S-shaped hook 3 made of a metal material having a length of about 6 cm, a width of about 3.4 cm, and a thickness of about 4 mm is used. Here, as shown in FIG. 3 and the like, the bed support portion 19 has a structure in which the tip is flipped upward, and the circular straight pipes 9 a and 9 b installed in the cultivation tank 8. The hook inner peripheral surface 20 is formed by being curved along the outer peripheral tube shape. At this time, as shown in FIG. 3, the locking hook 18 is inserted and engaged with the pipe hole 17 of the support column 4 from the tip, so that the downward movement of the S-shaped hook 3 is restricted. Therefore, the straight pipe 9a of the cultivation tank 8 can be supported from below by the portion of the hook inner peripheral surface 20, and the cultivation bed 2 can be maintained at a predetermined height.

  Next, the cultivation example of the strawberry 6 using the bench 1 of this embodiment is shown. First, the bench 1 of this embodiment is installed in the house (not shown) with the strawberry 6, and the hollow portion formed by the bending of the nonwoven fabric sheet 11 of the cultivation tank 8 is filled with the coconut shell medium 13 made of coconut shell, and the strawberry 6 seedlings are planted at predetermined intervals. At this time, in this embodiment, 5 to 10 strains of strawberries 6 are planted per one cultivation tank 8. In addition, the nonwoven fabric sheet 11 used has sufficient strength to withstand the weight of the coconut shell medium 13 and the strawberry 6 seedlings to be filled, and further supports and assists the nonwoven fabric sheet 11 from below by the net 10. Can do.

  Further, a water supply tube for supplying water for irrigation applied to a conventional elevated bench and a nutrient solution tube for appropriately supplying a chemical solution such as a nutrient solution are inserted into the coconut shell medium 13 and discharged from the coconut shell medium 13. A drainage tube for leading the drainage to the outside is inserted. In order to simplify the explanation, these tubes are not shown in FIG. And in these states, the coconut shell culture medium 8 of the cultivation tank 8 was appropriately watered, and the strawberry 6 was cultivated for about 6 months by controlling the indoor temperature of the house to a temperature suitable for growth (Fig. 4).

  Here, FIG. 5 shows the daily medium temperature change of the strawberry 6 under the above cultivation conditions. What is indicated by “▲” in the graph is the medium temperature of the palm shell medium 13 of the bench 1 having the cultivation tank 8 constituted by the nonwoven fabric sheet 11 of the present embodiment, and what is indicated by “●” is a comparison. As an example, it is the culture medium temperature of the coconut shell culture medium 13 when the expanded tank uses styrene foam, and what is indicated by “□” is the indoor temperature at that time.

  As a result, it was shown that the use of the S-shaped hook 3 as a coupling tool has a strength that can sufficiently withstand the load from the cultivation tank 8, the strawberry 6, and the coconut shell medium 3. Furthermore, it becomes possible to reduce the weight as compared with a conventional cultivation tank made of expanded polystyrene, etc., and the cultivation bed is easily supported by two workers even when the cultivation tank 8 is filled with the strawberry 6 and the coconut shell culture medium 13. It can be removed from the part 7 and moved to another place. At this time, the removal of the cultivation bed 2 does not require a particularly complicated operation. By holding a part of the cultivation bed 2 (for example, the straight pipes 9a and 9b) and lifting it upward, an S-shaped hook is obtained. The connection state of the cultivation bed 2 by 3 can be easily released (see FIG. 2). In addition, when crops, such as the strawberry 6, and the coconut shell culture medium 13 are removed, the said operation can also be performed by one worker.

  Moreover, as FIG. 5 shows, it is shown that culture medium temperature becomes low about 2-5 degreeC with respect to a comparative example by using the bench 1 (investigation example) of this embodiment. Furthermore, while the indoor temperature change is around 10 ° C., the change in the medium temperature of the coconut shell medium 13 of the bench 1 is around 5 ° C., and there is no sudden change in the medium temperature throughout the day. Here, in the case of summer and autumn strawberries, it is known that yield and profitability are improved by lowering the medium temperature. Therefore, it is shown that the bench 1 of the present embodiment, which is low in temperature and has little rapid temperature change, is particularly suitable for cultivation of summer and autumn strawberries.

  Furthermore, as described above, the connection of the cultivation bed 2 of the bench 1 can be easily released and moved to another place, so that the damage of the bench collapse due to snow accumulation in winter can be prevented. At this time, the support | pillar 4 of the cultivation bed support part 7 is standingly arranged in the perpendicular direction from the installation surface, does not receive the load by snow accumulation much, and there is almost no possibility of collapse. As a result, even in a cold region after the cultivation of summer-autumn strawberries over the summer and autumn seasons, the cultivation with the elevated bench 1 can be performed, and the labor burden on the operator can be reduced. it can.

  Moreover, by forming the cultivation tank using the nonwoven fabric sheet 11 as a main material, the cultivation bed 2 can be reduced in weight, and the one formed on the premise of the transfer of the cultivation bed 2 as in the present embodiment. Are particularly suitable. Furthermore, by using the nonwoven fabric sheet 11, the temperature of the coconut shell medium 13 can be kept lower than that of styrene foam and the like, which can contribute to the stability of the yield of strawberry 6 and the improvement of profitability.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the bench 1 of this embodiment, it illustrated about cultivating the summer autumn strawberry which mainly grows between summer and autumn as an agricultural product, but it is not limited to this, and the cultivation period is winter and spring. It may be winter strawberry and other crops other than strawberries. In particular, in the case of winter strawberry cultivated on a relatively warm climate, the bench collapses due to strong winds and rain caused by typhoons, or the fertilizer components contained in the medium are washed away by rainwater. May occur. Therefore, using the bench 1 of the present embodiment, during these seasons, the cultivation bed 2 is moved to a warehouse or the like so as not to have an influence of rainwater, or a large load is prevented from being applied to the support column 4 by a strong wind, Collapse can be prevented.

  Furthermore, in the bench 1 of this embodiment, what used the S-shaped hook 3 as a connection tool was shown, However, It is not limited to this, Other buckles, a belt, etc. can be connected and fixed mutually. It is possible to use known fixed couplings. However, the above-described buckle and the like are complicated to operate. On the other hand, since the S-shaped hook 3 of this embodiment can cancel | release a mutual connection state by simple operation which only lifts the cultivation bed 2 upwards, it is thought that it is especially suitable at the point which reduces operativity and labor. .

It is a perspective view which shows schematic structure of a bench. It is a disassembled perspective view which shows the state which removed the cultivation bed from the bench. It is explanatory drawing which shows the connection of the support | pillar and side support part by S character hook. It is explanatory drawing which shows the cultivation example of the strawberry which uses a bench. It is the graph which compared the culture medium temperature change of the bench.
