Description

Automatic plant cultivation system {AUTOMATIC PLANT CULTIVATION SYSTEM}

The present invention relates to an automatic plant cultivation system, and more particularly, it is possible to effectively cultivate plants while automatically transporting them to an inner space of a cultivation chamber in which a cultivation environment is created according to the growth stage, and the tray on which the plants are mounted is horizontal In addition, it relates to an automatic plant cultivation system that can conveniently perform the cultivation process and the harvesting process by transporting it in a vertical direction.

In general, a plant factory is a form of cultivating crops using an artificial light source. It is an agricultural technology that can produce plants year-round regardless of season or climate, and cultivate eco-friendly crops by removing biological and chemical harmful factors. Recently, various research activities are being conducted.

In the plant factory, plants are planted and plant cultivation devices are used to grow by receiving artificial lighting and nutrient solutions, and these plant cultivation devices are equipped with multi-layered plant cultivation units to increase space efficiency, and plant cultivation units of each layer are used. It is a general form that has a structure equipped with artificial lighting or a nutrient solution supply device.

For example, Korean Patent Registration No. 10-1703139 proposes a'plant cultivation device for indoor plant factories' as a plant cultivation device used in a plant factory.

The above-described plant cultivation apparatus 100 is provided in a square shape as shown in FIG. 1, and the power supply and monitor unit 10 for supplying power to the top and monitoring the growth conditions and processes of sowing and seeded plants. Is provided, and a moisture supply unit 20 for supplying moisture with nutrient solution to the planted and seeded plants is provided at the bottom, and in multiple stages at the lower portion of the power supply and the monitor unit 10 and the upper portion of the moisture supply unit 20 Each stage of the multi-stage is provided with a cultivation unit 30 for cultivating the planted and seeded plants in a wide cultivation area by expanding each of the front and left and right sides, and an energy storage device inside the power supply and the monitor unit 10 (40) and voice means (50) are provided.

The above-described conventional plant cultivation apparatus 100 can cultivate relatively large amounts of plants using a multi-stage cultivation unit, but there are various limitations since the main cultivation tray 31 in which the plants are grown is a fixed structure in which it is impossible to move.

First, plants need different cultivation environment conditions for each stage of growth, such as temperature, humidity, amount of light, and fertilization of nutrient solution and carbon dioxide in order to secure the best quality and efficient growth, but in the conventional stationary cultivation unit, the cultivation environment is appropriate for each stage of growth. There is a drawback that cannot be adjusted properly.

In addition, the conventional plant cultivation apparatus 100 requires a lot of time to be moved, such as the cultivation tray, etc., in the entire cultivation process of the plant, such as the cultivation process and the harvesting process, and thus increases the labor cost, as well as the efficiency of crop cultivation management. There is a disadvantage of being degraded.
