<p>The present invention relates to an agricultural sprinkler. The sprinkler spirally sprays water in the form of microparticles on a cultivation field for agriculture to promote growth of plants and to supply water to a large area by spraying water in the form of a cyclone. The rotary sprinkler for agriculture comprises: a support including an upper support and a lower support which are formed by bending both end portions of the supports to be placed apart from each other and to face each other; an water inlet which is installed on an end portion of the lower support and is penetrated to be formed in the shape of a cylinder with a diameter increasing from the top to the bottom; a flange that has a lower portion located in the water inlet to correspond to an inner diameter of the water inlet, and an upper portion which is exposed from an upper side of the water inlet, and includes a through-hole formed therein; a rotor that penetrates the center of the flange, includes inclined saw teeth in lengths different from each other on an outline of an upper side thereof, and also includes a hemispheric mount groove formed on the center thereof; a cyclone plate that includes a hemispheric protrusion, mounted on the mount groove of the rotor at the bottom-center of the rotor, and a spiral flow groove, which is formed in the radial shape on the outside of the hemispheric protrusion; and a cyclone plate support which is tightly inserted into the upper support and supports the cyclone plate.</p> |
