FIELD: mechanized sprinkler irrigation equipment, may be used on wheeled sprinkler pipelines. ^ SUBSTANCE: wide wheeled sprinkler is made sectional and equipped with sprinkler heads, wheeled supports, drive arranged in central part, and couplings for joining of sprinkler sections with one another. Each section is furnished with water supply pipeline made from low-pressure polyethylene pipes, which are connected in succession by couplings. Each of couplings is equipped with flanged semi-couplings having annular channels. Annular sealing members are located in said channels. Entry parts of semi-couplings are equipped with thread and arranged in end cavities of pipes to be connected. Pipe ends are embraced with sleeves providing for tight sealing of connections. Pipes and couplings are arranged in cavity of carrier member, which is defined by C-shaped bent profiles. Ends of bent profiles are connected with one another through disks. Disks on adjacent carrier members are connected with one another through half-rings, which are located in single plane with flanged semi-couplings. Hub of each wheeled pair embraces carrier member. Sprinkler heads are mounted on water supply pipeline by means of self-adjusting mechanisms on nipples oriented in space between strips of adjacent C-shaped bent profiles of carrier member. ^ EFFECT: prolonged service life and reduced costs for maintenance of wide wheeled sprinkler. ^ 4 dwg |
