A drive shaft that moves the cultivation tank 4 up and down, 8 is a shaft support that supports the drive shaft 7, 9 is a sprocket that transmits rotational torque to the drive shaft 7, 10 is a chain that transmits power to rotate the sprocket 9, and 11 is a cultivation tank. Perforated pipe for supplying fertilizer liquid, hot water, etc., 12 is a non-porous pipe for heating the inside of the cultivation tank with hot water, etc., 13 is a water supply tank to the hot water heater, 14 is a pipe connecting each device, and 15 is a hot water heater A water supply pump for supplying water, 16 is a hot water heater that generates hot water for heating, 17 is a fertilizer suction device that sucks up the fertilizer liquid by the flow of fluid in the pipe, 18 is a fertilizer liquid adjustment tank that adjusts the concentration of liquid fertilizer, and 19 Cut the flow in the pipe 20 is a fan that sends air to the cultivation tank 4 via the pipe 14, 21 is a flexible pipe that connects the fixed pipe 14 and the pipes 11 and 12 of the moving cultivation tank section, 22 is hot water for heating, and the remaining A return pipe for fertilizer liquid, 23 is a joint connecting the pipes to a predetermined length, and 24 is a greenhouse composed of a roof 1, a pillar 2 and a beam 3.

Although FIG. 1 shows a case where the cultivation tank 4 has 12 rows and one drive shaft 7 in the width direction of the greenhouse 24, the cultivation tank 4 is illustrated here from the left side to the right side in FIG. Cultivation tanks 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, and a suspension line 5 that connects the cultivation tank 4a and the cultivation tank 4h are suspended. 4b and 4i are suspended cables 5b-i, 4c and 4j are connected 5c-j, 4d and 4k are connected 5d-k, 4e and 4l are connected 5e-l, 4f and 4g The connecting cord is called 5f-g.

  As shown in FIG. 2, the suspension cables 5a-h, 5b-i, 5c-j, 5d-k, 5e-l, 5f-g are attached to the drive shaft 7 supported by the load supporting bracket 6 as shown in FIG. As shown in Fig. 4, the wire is wound clockwise and counterclockwise.

  For example, as shown in FIG. 4, the suspension cords 5a-h, 5c-j, 5e-l are wound around the outer periphery of the drive shaft 7 in the clockwise direction, while the suspension cords 5b-i, 5d-k, 5f -g is wound around the outer periphery of the drive shaft 7 in a counterclockwise direction.

  Therefore, if the drive shaft 7 shown in FIG. 4 is rotated clockwise, the suspension cords 5a-h, 5c-j, 5e-l wound in the clockwise direction are wound up on the left side of the drive shaft 7 in FIG. And is wound down on the right side of the drive shaft 7.

  That is, the cultivation tanks 4a, 4c, and 4e suspended from the suspension cords 5a-h, 5c-j, and 5e-l are lifted as shown in FIG. 3, and the cultivation tanks 4h, 4j, and 4l are suspended. Things will be easily understood.

  On the other hand, the suspension cables 5b-i, 5d-k, and 5f-g shown in FIG. 4 are wound around the drive shaft 7 in the counterclockwise direction, so that the drive shaft 7 shown in FIG. 4 can be rotated in the clockwise direction. For example, the suspension cords 5b-i, 5d-k, and 5f-g are wound down on the left side of the drive shaft 7 in FIG.

  That is, the cultivation tanks 4b, 4d, and 4f suspended by the suspension lines 5b-i, 5d-k, and 5f-g are suspended as shown in FIG. 3, and the cultivation tanks 4i, 4k, and 4g are suspended. Things will be easily understood.

  As a result, the adjacent cultivation tanks 4a and 4b, 4c and 4d, 4e and 4f, 4g and 4h, 4i and 4j, 4k and 4l hanging ropes 5a-h and 5b-i, 5c-j and 5d-k, As the winding directions of 5e-l and 5f-g are reversed, the adjacent cultivation tanks, for example, the cultivation tank 4a and the cultivation tank 4b move up and down in opposite directions. As a result, a space corresponding to the width of the cultivation tank 4b is created between the cultivation tank 4a and the cultivation tank 4c, and a work space can be created.

As shown in FIG. 2, a sprocket 9 and a chain 10 are attached to the drive shaft 7, and the drive shaft 7 can be rotated by operating the chain 10. When no operation is required, the chain 10 is hung on a hook (not shown) to prevent the drive shaft 7 from rotating due to the weight difference of the cultivation tank 4.

  Instead of the sprocket 9 and the chain 10, automatic operation by a reduction motor and a control device can be performed.

  Each cultivation tank 4a-4l has both a non-porous tube 11, both pores 2 or only a porous tube 12, or a porous tube 12 on the tank and a porous tube 12 along the length of the cultivation tanks 4a-4l. Are arranged. As shown in FIG. 5, when the cultivation tanks 4a to 4l are divided in the longitudinal direction, the nonporous tube 11 and the porous tube 12 are also connected by a joint 23 such as a flange. A flexible tube 21 is connected to the porous tube 11 and the non-porous tube 12 via a valve 19a. A water supply tank 13, a water supply pump 15, and a hot water heater 16 are installed in the greenhouse, and are connected to the perforated tube 11 and the non-porous tube 12 of the cultivation tanks 4 a to 4 l via the flexible tube 21 through the pipe 14. Further, a fertilizer liquid adjustment tank 18 and a fertilizer suction device 17 are connected to the hot water piping 4, and the fertilizer suction device 17 can be bypassed by switching the valve 19a. The surplus fertilizer liquid and hot water supplied to the cultivation tanks 4a to 4l are recovered to the water supply tank 13 and the fertilizer liquid adjustment tank 18 via the return pipes 22a and 22b and the switching valve 19a.

  In this way, when there is no farm work in each of the cultivation tanks 4a to 4l, heating by the non-porous pipe 12, and fertilization by the porous pipe 11, all the cultivation tanks 4a to 4l are suspended at the non-working positions shown in FIG. ing. When the cultivation tanks 4a, 4c, 4e, 4g, 4i, and 4k are sterilized or harvested, the chain 10 and the sprocket 9 rotate the drive shaft 7 counterclockwise to grow the cultivation tanks 4a, 4c, and 4e. 4g, 4i, 4k are lowered to the working position and 4b, 4d, 4f, 4h, 4j, 4l are raised to work. After the operation of the cultivation tanks 4a, 4c, 4e, 4g, 4i, and 4k is completed, if the drive shaft 7 is rotated in the reverse direction, the cultivation tanks 4a, 4c, 4e, 4g, 4i, and 4k are raised. The cultivation tanks 4b, 4d, 4f, 4h, 4j, and 4l, which are located at a high position, are lowered and become ready for farming. That is, the raising and lowering of the cultivation tank 4 can be achieved with a very simple structure including only the suspension rope 5, the load supporting bracket 6, the drive shaft 7, and the sprocket 9 and the chain 10 as the drive device, and 12 rows of cultivation. Move the tank group up and down in one operation, lower half of the cultivation tanks to the farming position, raise the remaining cultivation tanks to create a work space between the cultivation tanks, and reverse the cultivation tanks that have moved up and down in the next operation By doing so, farming of all cultivation tanks becomes possible. After the work is completed, it can be brought back to the non-farm work position and grown by a single operation.

  The necessary force when rotating is only a cultivation tank at both ends of the suspension line 5, for example, the mass difference between the cultivation tank 4 a and the cultivation tank 4 h and the friction load when the suspension line 5 passes through the load supporting metal 6. Most of the mass of the cultivation tanks 4a and 4h themselves are balanced in both. The difference in mass between the cultivation tanks 4a and 4h is rarely increased only in the cultivation tank arranged on one side of the drive shaft 7, and the mass difference to the drive shaft 7 is equalized by placing a plurality of cultivation tanks 4a to 4l. Is done. The friction of the load support fitting 6 can be reduced by using, for example, a pulley, and the force can be reduced by the difference in diameter between the sprocket 9 and the drive shaft 7, so that the force pulling the chain 10 may be small.

  Note that the suspension rope 5a-h is prevented from slipping due to a difference in mass between the left and right cultivation tanks, for example, the cultivation tank 4a and the cultivation tank 4h, by winding the suspension rope 5a-h around the drive shaft 7. This is because the friction coefficient is usually about 0.3 or more, and the friction load in this case is the tension of the suspension rope 5a-h, that is, the mass of the cultivation tanks 4a and 4h. It is easy to set the mass difference between the normal cultivation tanks 4a and 4h to be equal to or less than the mass X friction coefficient, and the autonomous movement of the cultivation tanks 4a and 4h due to the sliding of the suspension rope 5a-h does not occur. However, if there is a mass difference between the cultivation tank group on the left side and the cultivation tank group on the right side of the drive shaft 7 and the total frictional force of the load supporting bracket 6 is greater, the whole may move up and down arbitrarily. The shaft 7 requires a device for preventing rotation. Although not shown in the present invention, an undesired rotation of the drive shaft 7 can be easily stopped by attaching a stop device to the chain 10.

  In this way, the suspension cords 5a-h, 5c-j, 5e-l and the suspension cords 5b-i, 5d-k, 5f-g are repeatedly lifted or suspended from each other. As shown, a space is formed below the suspended cultivation tanks 4a and 4c, and the suspended cultivation tanks 4b and 4d can be used as farm work spaces and passages.

  In the cultivation tank 4, as shown in FIGS. 3 and 6, both the non-porous tube 11 and the porous tube 12 are arranged, or only the porous tube 12 shown in FIG. 5 is arranged, or the non-porous tube 11 Only the porous tube 12 is arranged on the cultivation tank. In plants where the heating time and fertilizer supply time overlap, both the non-porous pipe 11 and the porous pipe 12 are arranged in the cultivation tank 4 as shown in FIGS. In this case, only the perforated pipe 12 is piped as shown in FIG. 5, and for the plants in which the heating time and the fertilizer supply time do not overlap, the porous space 12 serves both as heating and fertilizer supply. Circulating return hot water and surplus fertilizer liquid directly supplied to the cultivation tank 4 from the hole of the perforated pipe 12 are collected in the water supply tank 13 and the fertilizer liquid adjustment tank 18 via return pipes 22a and 22b. When the non-porous pipe 11 for heating is used, after leaving the other end of the cultivation tank 4, it is connected to the return pipe 22b and circulated.

  In this way, by flowing hot water into the cultivation tank 4, the root part of the plant is heated, and heat is dissipated to the greenhouse air having a lower temperature than the root part, and heat is dissipated outside the greenhouse from the low-temperature greenhouse air. Therefore, it becomes less heating energy than the conventional method of heating the greenhouse air itself.

The heat dissipated from the cultivation tanks 4a to 4l heated by the hot water raises the space temperature around the cultivation tank. By arranging the cultivation tanks 4a to 4l at a high place, the indoor air temperature below the cultivation tanks 4a to 4l may be lower than the growth temperature, and the dissipation loss from the greenhouse 24 is reduced accordingly. In general, the temperature around the leaves required by plants may be lower than that around the roots. By raising the temperature around the root stock by internal heating of the cultivation tanks 4a to 4l, the air temperature around the leaves and above the cultivation tanks 4a to 4l also rises, but this effect becomes greater as the cultivation tanks 4 are more densely packed. In the dense cultivation where the gap between the cultivation tanks 4a to 4l is almost unnecessary as in the apparatus of the present invention, when the necessary temperature around the root is 20 ° C. and the leaf circumference is about 10 ° C., the cultivation tank 4a even when the outside air temperature is −5 ° C. The greenhouse temperature above the cultivation tank group can be kept at the required temperature of the leaves only by heating ~ 4 l. That is, in the present invention, the temperature of the space around the leaves can be managed low by setting the cultivation tank temperature to the required temperature, and the heat dissipation from the greenhouse wall can be reduced.

  A fan 20 is connected to the hot water pipe 14 via a switching valve 19b. When heated by directly supplying hot water through the perforated pipe 12, it is a valve for plants that need to supply oxygen to the root by replacing the liquid around the root with air in a time shorter than the natural fall time of the hot water. The piping route is switched by operation, and air is supplied by the fan 20.

  FIG. 7 is a partially enlarged view of a cross-sectional view showing the configuration and positional relationship of a two-stage cultivation tank according to another embodiment of the present invention, and FIG. 8 is vertically interchangeable according to another embodiment of the present invention. The partial enlarged view which shows the structure and positional relationship of a two-stage cultivation tank is shown. In FIG. 1, only one stage of the cultivation tank is suspended in each cultivation tank row, but two stages of cultivation tanks are suspended in FIGS. If the mass of each cultivation tank of the suspension rope 5 is substantially the same, it can also be made into the mixture of a one-stage cultivation tank and a two-stage cultivation tank. In the case of this multi-stage arrangement, the ratio of light reception time is averaged by operating the drive shaft 7 and periodically changing the vertical position of the adjacent cultivation tank rows in order to reduce the sunshine and illumination ratio to the lower stage. I can do it.

In the case of two stages, even if the upper and lower positions of adjacent cultivation tanks are interchanged, a difference occurs in the light receiving time of the upper and lower cultivation tanks in each row. In FIG. 8, in order to equalize the light receiving time of all the cultivation tanks, the drive shaft 7 is composed of two of 7a and 7b, the spacers 25 are provided in the upper and lower cultivation tanks 4a1 and 4a2, and the drive shafts 7a and 7b are arranged. If rotating in the same direction, the heights of the cultivation tanks 4a1, 4a2 and cultivation tanks 4b1, 4b2 are changed, and if the drive shafts 7a and 7b are rotated in opposite directions, the cultivation tanks 4a1 and 4a2, the cultivation tank 4b1 The height of 4b2 can be changed. When the cultivation tanks 4a1 and 4a2 are replaced, the spacer 25 keeps the distance between the cultivation tank 4a1 and the cultivation tank 4a2, so that mutual interference at the time of replacement can be prevented. In addition, FIG. 8 has shown the example which has arrange | positioned the number of rows of the cultivation tank 4 to the right and left of the drive shaft 7, respectively.
