Description

  The present invention relates to a plant cultivation facility constructed for cultivating plants in a cultivation room, and in particular, this invention sends temperature-regulated air to a plant cultivation space of each stage of a plant cultivation device having a multi-stage cultivation shelf. The present invention relates to a plant cultivation facility for preparing an environment suitable for growing plants.

  BACKGROUND ART A plant cultivation apparatus having a multi-stage cultivation shelf is used for cultivating a plant such as a vegetable in a cultivation room. An illuminating device that irradiates light to a plant cultivation space on the cultivation shelf is installed above the cultivation shelf in each stage. In order to grow the plants in each cultivation shelf equally, an appropriate amount of temperature-regulated air is distributed to the cultivation space in each tier, so that the temperature and humidity of the cultivation space in each tier are almost the same over the entire area. Need to be kept. When the lighting device is turned on, the temperature of the plant cultivation space increases due to the heat generated by the lighting device. If an appropriate amount of air does not reach the plant cultivation space, the temperature of the plant cultivation space does not become the same over the entire area, resulting in uneven temperature.

  In the cultivation room, a plurality of plant cultivation apparatuses are generally installed in parallel with a passage therebetween. As this kind of plant cultivation equipment, among a plurality of passages, there is a plant in which a first passage in which an air conditioner is installed and a second passage in which an induction fan is installed are alternately provided (for example, see Patent Document 1). ). In this plant cultivation facility, air whose temperature has been adjusted is sent out from the air conditioner to the first passage, and the air is drawn into the second passage next to the air by the induction fan, so that an airflow is generated, and the air is generated on the cultivation shelf. An appropriate amount of air passes through the plant growing space.

  However, in the plant cultivation equipment described in Patent Literature 1, there is a problem that equipment costs increase because air conditioning equipment is installed in a plurality of passages. Also, it is not easy to spread the temperature-adjusted air to the plant cultivation space of each stage, and when the lighting device is turned on, in the plant cultivation space of each stage, the temperature does not become the same over the entire area, and the temperature unevenness occurs. There is also a problem that occurs.

  The present invention has been made in view of the above problems, and can be constructed at a low cost without using a large number of air conditioners. It is an object of the present invention to provide a plant cultivation facility capable of performing the following.

The plant cultivation equipment according to the present invention includes a plurality of plant cultivation devices having a plant cultivation space on a multi-stage cultivation shelf, which are installed in parallel in a cultivation room with a passage therebetween, and a position above an end of each of the plant cultivation devices. A plurality of air inlets for feeding the temperature-adjusted air to a lower cultivation room, an air conditioner communicating with the plurality of air inlets via a duct, and a longitudinal direction of the plant cultivation apparatus below the air inlet. The second blower includes a second blower arranged at a plurality of height positions along the side surface of the plant, and the temperature-adjusted air sent from the air supply port to the cultivation room at each height position is supplied to the plant by the second blower. A rectifying mechanism that adjusts the flow of air along the longitudinal side surface of the cultivation device, and the air flowing along the side surface that is arranged at a predetermined interval by shifting the vertical position to a position along the longitudinal side surface of the plant cultivation device. On the cultivation shelf of each stage It is obtained by a first of a plurality of feeding the object cultivating space 1 of the blower.

In the plant cultivation facility having the above-described configuration, air whose temperature has been adjusted by the air conditioner is sent into the cultivation room from the air supply port , and the air is adjusted to a flow of air along the longitudinal side surface of the plant cultivation apparatus by the rectification mechanism. . Since the plurality of first blowers are arranged at positions along the longitudinal side surface of the plant cultivation device, the air flowing along the longitudinal side surface of the plant cultivation device is supplied to the cultivation shelves of each stage by the first blower. It is sent to the upper plant cultivation space. When the temperature of the plant cultivation space of each stage rises due to the lighting of the lighting device, the temperature-adjusted air spreads over the entire area of the plant cultivation space of each stage, so that there is no temperature unevenness in the plant cultivation space.

  Various embodiments can be considered as the rectifying mechanism, but one embodiment is a second blower arranged at a predetermined height position along the side surface in the longitudinal direction of the plant cultivation apparatus, and a vicinity of the installation position of the second blower. And a windbreak plate arranged at the bottom. The windbreak plate has a collision surface for directing a part of the flow of the air from the air supply port toward the second blower.

  In this embodiment, a part of the flow of air from the air supply port is directed toward the second blower by colliding with the collision surface of the windbreak plate, and the direction of the airflow from the second blower in the longitudinal direction of the plant cultivation apparatus is increased. Conditioned to the flow of air along the sides. Another part of the flow of the air from the air supply port goes downward through the position of the windbreak plate.

  When a plurality of plant cultivation devices are installed in the cultivation room, it is desirable that one plant cultivation device be installed at each side end position in the cultivation room and an even number be installed at an intermediate position in parallel with each other. In this installation mode, the first blower is installed in an adjacent pair of plant cultivation devices at an intermediate position toward another pair of plant cultivation devices on the side facing each other, and is provided on both side walls of the cultivation room. It is installed toward the plant cultivation device at the end position.

  In the above embodiment, passages are interposed between the side wall of the cultivation room and the plant cultivation device at the side end position, and between the pair of plant cultivation devices at the intermediate position.

  In this embodiment, when the passage widths of both passages are set to be substantially the same, in each plant cultivation device, air is sent from the first blower to the plant cultivation space under the same conditions, and each plant cultivation device is in the same environment. Is set. When the passage width of each passage is different, it is necessary to adjust the air volume of the first blower to set each plant cultivation apparatus in the same environment.

  In a preferred embodiment, the plant cultivation apparatus is provided with a work scaffold made of a perforated steel plate at a predetermined height in a high place.

  According to this embodiment, since the steel plate constituting the scaffold has air permeability secured by the holes, there is no possibility that the scaffold will obstruct the flow of air.

  According to the present invention, since a large number of air conditioners are not used, plant cultivation equipment can be constructed at low cost. Moreover, in the plant cultivation space of each stage, it is possible to spread the temperature-regulated air over the entire area, and it does not cause uneven temperature. Furthermore, by controlling the operation of the first blower on a region basis, it is possible to prepare different environments for each cultivation area, without providing a partition wall, etc., according to the type of plant and the lighting time of the lighting device, Temperature conditions suitable for cultivation can be adjusted.
