Description

Rotatable plant cultivator

A rotary plant grower is disclosed. More specifically, a rotary plant cultivator with improved productivity, convenience and safety is disclosed.

A plant cultivator is a device that artificially supplies light, moisture, soil, and temperature necessary for plant growth to enable plant cultivation.

Conventionally, to maximize production, plant growers that consist of drum-type rotary and conveyor types of plant growing beds are the mainstream, and some multi-stage bed rotary plant growers are also under research and development. However, it is difficult to supply sufficient natural light in the conventional plant grower of the production maximization method, and the height of the plant cultivation bed is too low or too high, which causes difficulties in harvesting, and in particular, there is a trade-off in which it is difficult to supply nutrient solution or irrigation. . In addition, as the system becomes relatively complicated, the installation cost per unit area also increases, so that the selling price is also high. In addition, there is a problem in that the product preference of the farmers is low due to the high selling price, which is difficult to purchase in a farmhouse with no economic leeway, and the supply and supply to the actual farms are limited because it does not significantly contribute to the income of the farmhouse.

As another example, there is a fixed multi-stage plant cultivation machine, which is configured in the form of a vertical farm (plant factory) in which cultivation beds are vertically stacked, so that the production per unit area is high. However, since the height of the greenhouse in rural areas is usually limited to 3-4m, it is difficult to apply the fixed multi-stage plant grower to the farmhouse. There are inherent problems.

In addition, the existing plant grower has a disadvantage in that it is not satisfactory in terms of work convenience of a producer (worker) when harvesting cultivated plants by focusing on maximizing production. For example, some plant growers have a work bed that is too low, so they have to bend their backs or squat to do the work. Another plant grower has an inconvenient production operation and inherent risk of a fall accident because the work bed is too high, so it is necessary to work with a high ladder, and to work while moving horizontally.

Also, with respect to the nutrient solution supply method, the existing fixed multi-stage plant growers in Korea mainly use Deep Flow Technique (DFT) cultivation and NFT: Nurient Film Technique (NFT) cultivation. In addition, the existing fixed multi-stage plant cultivation machines abroad mainly adopt SP (Spray Culture) cultivation. In addition, existing domestic rotary, conveyor, and bed rotary plant growers mainly adopt a method of spraying nutrient solution or water through a nozzle from the top or side. In this way, the method of spraying nutrient solution or water through the nozzle exposes the corresponding device and acts as an obstacle during worker movement or harvesting, thereby reducing work efficiency.

In addition, in the case of cultivating leafy vegetables such as leafy vegetables or leafy vegetables, when supplying a nutrient solution using an upper or side nozzle spray method, a part of the nutrient solution remains on the leaves and evaporates or is sprayed to the outside, resulting in unavoidable loss. In addition, the nutrient solution accumulated in the leaves may interfere with photosynthesis or may be directly ingested by humans, which may adversely affect the health of consumers as well as nutrient deficiency of vegetables.

In addition, with respect to the sunlight supply method, in the case of the existing fixed multi-stage smart farm plant cultivation machine, technology development is being made entirely for plant factories using LED artificial light, which consumes a lot of energy and uses natural light. There is a problem that it is impossible to apply it to a rural smart farm vinyl house. In the case of the existing rotary, conveyor, and bed rotating smart farm plant cultivation machines, technology development is being carried out in a rotation method or a conveyor vertical movement method in order to increase production and natural light utilization. However, some plant growers have a problem in that although an LED light source is fixedly installed on the upper side or the side to provide light, a sufficient light source cannot be secured, and energy consumption is generated by maintaining a continuously lit state. In another plant grower, an LED light source is fixedly installed on the upper part of the cultivation bed to maintain the lighted state while receiving light, thereby generating a lot of energy consumption. As such, the conventional plant grower has disadvantages in that the utilization rate of natural light is low, the ratio of the upper bed blocking the light of the lower bed is high, and the energy consumption is high. In addition, some plant growers selectively use blue or red LED light sources suitable for photosynthesis of plants, and in some cases, they do not help plants photosynthesis by using general white LED light sources.

In addition, with respect to safety devices, the existing motor-driven plant growers for smart farms are turned ON/OFF by manual control of the power switch and remote control by a remote controller. There is a high risk of human accidents if the power source is operated without checking the worker during harvesting in the plant growing machine, but the existing plant growing machine does not have a separate safety device.
