Watering head

摘要

The invention relates to a watering head for the drop feed irrigation mainly of orchards with impermeable soil. It consists of two main parts, i.e. the body connected to the watering pipeline, and the replaceable feeder unit mounted on the body. Occasionally the body and the feeder unit are constructed from one piece. The feeder unit is a prism, or body of rotation extending in the longitudinal axis, the interior of which is provided preferably with a spatial spiral polygonal braking duct reducing the flow velocity of the irrigation water. One end of the braking duct leads into the part, e.g. receiving sleeve pulled over the body-suitable for connection of the feeder unit and body to each other, while the other end is developed as a drop feed orifice for discharge of the irrigation water.
