FIELD: agricultural engineering. ^ SUBSTANCE: invention relates to finely divided and drop sprinkling irrigation and it can be used in mobile plants for forming drops of rail with size of drops tolerable for irrigation of wide spectrum of crops. Head includes body mounted on water supply pipeline and baffle secured on post. Body consists of mated cylindrical and conical parts and accommodates flow guide. It is made of two different-size cones with common base. Smaller cone is arranged in cylindrical part of body. Rubber cord is secured on side surface of larger cone over screw line. Diameter of cord is equal to distance between walls of conical part of body and side surface of larger cone. Lower part of body is provided with plate fairing. Baffle has threaded rod to fix different-size cones in body. ^ EFFECT: provision of setting of optimum parameters of rail drops, improved reliability ion operation. ^ 3 cl, 2 dwg |
