20120097769 | DRIP IRRIGATION EMITTERS WITH MANUALLY ADJUSTABLE WATER DIRECTING STRUCTURE - An emitter to be used for drip irrigation is described. It includes a base equipped with a plunger that can be inserted into a drip irrigation pipe. The base is shaped to hold a spherical rotating member. This rotating member is traversed by a conduit that direct the water flow from the plunger to a spout located on top of the rotating member. An annular cap screwed or snapped on top of the base holds the rotating member in place. The emitter can be mounted on an irrigation pipe by punching a hole in the pipe and inserting the plunger. The rotating member can be directed to the desired direction by slightly unscrewing the cap, adjusting the position of the rotating member and retightening the cap. | 04-26-2012 |
