Abstract

PROBLEM TO BE SOLVED: To provide a plant growing device for intermittently supplying water and fertilizer to plant roots in a plant factory, and at the same time, facilitating night time setting in plants to reduce initial investment cost.SOLUTION: This plant growing device is such that a plant growing bed putting roots into the outside is set in the surroundings of a rotary case frame, and a liquid fertilizer tank with an opened upper surface is set on the lower part of the product so as to enable fertilizer supply, and at the same time, a light source is set on the central part of a rotary shaft, and two shielding plates extending in a radiation direction from the light source are attached so as to extinguish a light source therebetween and allow a nighttime state of an arbitrary length.

Description

  The present invention relates to a plant factory that cultivates vegetables and the like stably and safely without using a pesticide, regardless of the weather.

  Many plant growing devices known as plant factories are known as devices that can grow vegetables and the like stably without being influenced by the weather. Plants are cultivated with roots immersed. However, if the roots of plants to be grown are immersed in liquid fertilizer, there is a problem that oxygen concentration in the liquid is insufficient and growth is hindered, and aquatic is generated in the retained liquid fertilizer. In many cases, a large-scale device such as a liquid fertilizer circulation device is required.

  In plant factories, it is not necessary to continue to illuminate the light source, but it is necessary to create an appropriate nighttime state to grow the plant smoothly, but a plant that can arbitrarily set the ratio of the nighttime state in the day with a simple device No training device is known.

  In order to solve these problems, an object of the present invention is to provide a plant growing device capable of supplying liquid fertilizer easily and intermittently and at the same time supplying oxygen by periodically contacting the air with the root. To do. It is another object of the present invention to provide a plant growing device that can set a nighttime state with a simple device and at the same time arbitrarily determine a nighttime ratio in a day.

  The present invention has a light source inside a polygonal casing provided with a support shaft horizontally, a growing floor on each side of the polygon, and leaves the casing inside so that the roots grow on the outside. Solving the above-mentioned problem by providing a plant growing device in which a root portion can be pickled and supplied to a liquid fertilizer tank provided at the lower portion by rotating the body so that the upper surface is opened. .

  In addition, the present invention is provided with a plurality of light shielding plates extending in the circumferential direction from the light source and provided at an arbitrary angle with respect to being able to arbitrarily set a night state, and the light source is turned off while being sandwiched between the light shielding plates. This solves the problem by providing a plant growing device that rotates the device and creates a night condition on the growing floor.

  According to the plant growing device of the present invention, there is an advantage that oxygen can be supplied by supplying the liquid fertilizer easily and intermittently and at the same time the root periodically touches the air. Moreover, according to the plant growing apparatus of this invention, the advantage that the nighttime ratio in one day can also be arbitrarily determined at the same time can be set with a simple apparatus.

FIG. 2 is a front view showing an example of a plant growing apparatus of the present invention. These are side views which show an example of the plant growing apparatus of this invention.

  Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to those shown in the drawings.

  FIG. 1 is a front view showing an example of a plant growing apparatus of the present invention, in which a plurality of growing floors 2 are installed in a polygonal housing 1 and plants 3 are vegetated inward. The root 4 of the plant is in a state of extending outward. The housing 1 is supported by a support shaft 5 and rotates as indicated by an arrow A. A light source 6 is installed around the support shaft 5. In this description, the casing 1 is described as a polygon, but it is needless to say that it may be circular. The polygon is optimal from a quadrangular to a dodecagon.

  A liquid fertilizer tank 7 having an open upper surface is provided at the lower part of the rotating housing 1, in which liquid fertilizer 8 is injected, and the roots of the plant extending from the growing floor 2 rotating with the housing 1. By soaking 4 in the liquid fertilizer 8, the plant 3 can absorb active ingredients such as fertilizer and moisture.

  From this, it is also possible to adjust the fertilization amount with respect to the plant 3 by adjusting the speed at which the housing 1 rotates. The housing 1 can be rotated by rotating the support shaft 5 with an electric motor, and the rotational speed can be adjusted by changing the rotational speed of the electric motor.

  Further, when the light source 6 is attached around the support shaft 5 without rotating in the same manner as the support shaft, the light source 6 can be detachably attached to the support shaft 5 at an arbitrary position in the circumferential direction of the support shaft 5. As shown in FIG. 1, the light shielding plate 9 and the light shielding plate 10 are installed in the radial direction from the support shaft 5, and the light source 6 between them is turned off, so that a night state can be created for the plant 3.

  By setting the angle of the light-shielding plates 9 and 10 and the rotation number of the housing 1 arbitrarily, it is possible to provide an optimal night time for plants to be grown. In this description, the light source 6 is fixed. However, it goes without saying that the light source 6 may be rotated together with the support shaft 5 so that the light source 6 rotates and only the light shielding plates 9 and 10 are turned off.

  In the present invention, the light source between the light shielding plates 9 and 10 can be removed if a specific night time in the plant is set. In such a case, the number of the light sources 6 can be reduced, and the initial investment in the plant factory is possible. It is possible to have an advantage that can be reduced.

  FIG. 2 is a side view of the plant growing apparatus of FIG. 1, and the support shaft 5 is supported by a support shaft base 11.

  Since the plant growing apparatus of the present invention is configured as described above, liquid fertilizer can be easily and intermittently supplied, and at the same time, oxygen can be supplied by periodically contacting the air with the root, which is stable and hygienic. Plants can be cultivated. Further, according to the plant growing device of the present invention, it is possible to set the nighttime state with a simple device and at the same time arbitrarily determine the nighttime ratio in the day, so that the growing environment according to the characteristics of each plant is easy. Can be realized. The plant growing apparatus of the present invention having such excellent advantages has great industrial applicability.
