Description

Height-adjustable modular plant grower

[0001] The present invention relates to a modular plant cultivator with adjustable height, and more particularly, to a plant cultivator with adjustable height by installing a drive chain capable of moving trays up and down in the lower module and the upper module, and adjusting the number of intermediate modules installed between the lower module and the upper module.

[0002] Recently, plants have been cultivated using facilities such as vinyl greenhouses and glass greenhouses, which are not affected by climate change. These facilities use plant cultivation machines to cultivate plants.

[0003] A plant cultivation device is a device that allows for the cultivation of plants by artificially supplying the light, moisture, and soil temperature necessary for plant growth. The device contains multiple trays with storage spaces for the crops, and the crops are grown in these trays.

[0004] However, conventional plant cultivation systems suffer from the following problems. Facilities such as vinyl greenhouses and glass greenhouses can vary in height depending on their installation environment. The height of the plant cultivation system must be adjusted accordingly, but conventional plant cultivation systems are fixed in height, making it difficult to easily adjust their height.

[0005] In addition, there is a need to adjust the height of the plant cultivation equipment depending on the crops being grown in facilities such as vinyl houses and glass greenhouses, but there is a problem that it is difficult to adjust the height of the plant cultivation equipment using conventional plant cultivation equipment.

[0006] Meanwhile, the plant cultivation machine includes a plurality of trays that are provided with a space for storing crops, but there is a problem in that the work efficiency of the worker is reduced due to the height at which the trays are installed in the plant cultivation machine.

[0007] For example, if the tray height is installed too low, the worker has to bend over or squat to work, which reduces work efficiency. If the tray height is too high, the worker has to use a ladder to work, which reduces work efficiency.

[0008] Furthermore, when multiple trays are installed vertically in a plant cultivation system, the amount of sunlight received by the crops may vary depending on the tray height. This creates a problem where crops grown on trays of different heights experience different growth conditions, as the crops do not receive even sunlight depending on the tray height.

[0009] The present invention is intended to solve the above-described problem, and more specifically, relates to a plant cultivation machine capable of adjusting the height by adjusting the number of intermediate modules installed between the lower module and the upper module while installing a drive chain capable of moving trays up and down in the lower module and the upper module.
