YH Industry Co., Ltd. is an agricultural machinery company specializing in the development and manufacturing of vertical oscillating unmanned spraying systems designed to improve pest and disease control efficiency and reduce labor in greenhouse horticulture farms. Our company develops spraying equipment that applies a vertical oscillating spraying technology suitable for greenhouse environments, enabling chemicals to be evenly delivered to the upper, middle, and lower parts of crops. Through this technology, we minimize spraying blind spots that often occur in conventional spraying methods and provide improved spraying efficiency.

The vertical oscillating spraying method is a spraying technique in which the spray nozzle repeatedly moves up and down while applying pesticides. This method is designed to allow the chemicals to reach the upper, middle, and lower parts of crops evenly, depending on the crop height and planting density. Conventional spraying methods often discharge chemicals only in a horizontal direction, which can make it difficult for the chemicals to sufficiently reach the inner or lower parts of crops. In contrast, the vertical oscillating system changes the spray angle as the nozzle moves up and down, and its key advantage is reducing spraying blind spots within the crop canopy.
