HYBRID EMITTER AND METHOD OF INTEGRATING EMITTERS AND ACCESSORIES WITHIN IRRIGATION PIPE

摘要

The hybrid emitter of low discharge for water or solutions is inserted and welded into a pipe (2) during the production phase. The hybrid emitter bears at its convex and cylindrical surface (24) local protrusions (45) that are covered completely from the pipe (2) which is swelled locally. The water exits preferably from two nozzles (44) that are created within the protrusions (45) by the cutting off of the tips which protrusions protrude and after cutting off said nozzles eject the water almost cross wise to two opposite directions and at short discrete distances left and right of the pipe. Method for welding of emitters and accessories into a pipe (2) where the emitter or the hybrid one (14 40) with or without protrusions (18 45) on the outer surface (24) are inserted into the pipe (2) during its production phase. The hybrid emitter (14 40) is compressed by two elastic wheels (20) with their shafts drawing an angle between them of 45° to 90° that are positioned externally of the extruded pipe (2) and rotate with the peripheral velocity V of the extrusion been driven by an independent motor. The cutting off of the tips is performed by rotating fraises (77) that bear teeth blades with circular and conical cutting profile. The form of the pipe is maintained cylindrical during the cutting off by arrays of concave and cylindrical rollers arranged under a 120° angle covering the entire periphery.
