<p>The present invention relates to an automatic spray device for a greenhouse, wherein the automatic spray device is composed of a main body, a fixing support, a spray controller, and a battery. The main body is formed on the entire surface of a support plate. The main body includes: a rotator connecting an upper roller formed on one side of an upper part of the support plate and a driving device formed on one side of a lower part of the support plate; a floating groove formed in a rear surface of the support plate in a length direction; a power pipe flowing by a length of the floating groove; and a switch operation member formed on one side of the main body to operate the switching of a power switch. The fixing support is formed on one side of the support plate. The fixing support includes: a slide hole formed in an inside of the fixing support; a slide member capable of sliding in the slide hole; a shaft which is shaft-installed at one side of the slide member; a pinion and a lower roller, which rotate in engagement with the rotator on an outer circumference of the slide member; and elastic members respectively connected to an outer circumference of the shaft and one side of the support plate. The spray controller includes: a hose locking device formed at one side of a hose connected to a lower part of the main body; and a wire connected to one side of the hose locking device and one side of the power pipe to operate the hose locking device by an operation of the power pipe. The battery is connected to the lower part of the main body to supply power to the driving device. Therefore, the present invention can solve a cause of a short circuit or an electric shock, reduce separate manpower through automatic operation, and promptly perform spraying while providing convenience, and thus the present invention has very excellent effects of preventing crop damages by blight and harmful insects and reducing the time.</p> |
