Description

  The present invention relates to a plant cultivation apparatus that uses, for example, an LED lamp as a light source and is used in a plant factory, a vegetable factory, a seedling raising apparatus, or the like.

  In this specification and claims, the top and bottom, left and right in FIG. 1 are referred to as top and bottom, and left and right, the left side in FIG. 2 is the front, and the opposite side is the back.

  As a plant cultivation device using an LED lighting device, the present applicant previously has a cultivation rack having a mounting portion on which a cultivation tank in which a plant is planted and a lighting device disposed above the mounting portion. The cultivation rack is formed by combining a plurality of vertical members and horizontal members, and the support portion includes a pair of left and right receiving members that are arranged at intervals in the left-right direction and extend in the front-rear direction; The device is composed of a frame-like frame made of four aluminum extruded profile frame members fixed to each other and a plurality of LED lamps detachably attached to the frame, and both left and right frame members of the frame of the lighting device are The plant cultivation apparatus received by the receiving member of the support part was proposed (refer patent document 1).

  However, in the plant cultivation apparatus described in Patent Document 1, since the lighting device includes a frame assembled by fixing four aluminum extruded shape frame members, the number of parts increases and the number of assembly steps increases. As a result, the cost increases.

  Further, when assembling the frame by fixing the four frame members, a relatively wide work space is required. Therefore, in general, the four frame members are fixed to the frame at a manufacturing site separate from the plant factory. After being assembled, it is designed to be transported to plant factories where plant cultivation equipment is installed, but because the frame is large and heavy, the transportation work is difficult and relatively Large transport space is required. Therefore, there are problems that many frames cannot be transported at the same time and a relatively large packing material is required, resulting in a high transport cost.

  Further, when attaching the lighting device to the cultivation rack and when removing it from the cultivation rack, it is necessary to handle a heavy frame, which makes these operations difficult. Moreover, when attaching the lighting device to the cultivation rack and when removing it from the cultivation rack, it is necessary to handle a large frame, so a relatively wide working space must be provided on the front side and / or the rear side of the cultivation rack. Rather, a plant factory or the like needs a relatively large space unrelated to plant cultivation.

Japanese Patent Laying-Open No. 2015-6162

  The objective of this invention is providing the plant cultivation apparatus provided with the illuminating device which solved the said problem, reduced the number of parts and the number of assembly processes, and achieved reduction in size and weight.

  In order to achieve the above object, the present invention comprises the following aspects.
