SPRINKLING IRRIGATION EQUIPMENT Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: equipment has arc-type pipeline 1 with straight ends and nozzles along the arc stretch. The free end of the pipeline is fixed into body 4 of revolving mechanism to engage with drum-shaped support 5 which has an internal axial pipe. Nipple 6 is attached to the end of the support and serves for connecting the water supply system. Regulating discs 7 are fixed into the internal axial pipe. Each disc has a ring-type slot and bulge to limit the revolution of regulating discs about each other. In body 4 of the revolving mechanism, there is turbine 8, water flow distributing block 9 and pressure reducing box 10. Block 9 has shell 11. The end of shell 11 is closed with disc 13 which is provided with two axles 14 (for box 10) mounted in cantilever and two pipes 15 which also extend in cantilever. Shell 11 and disc 13 are fitted onto shaft 19 the free end of which enters the internal axial pipe of drum support 5. Pipe 15 forms common water outlet slit 22 in whose zone blades of turbine 8 are located. The turbine is freely mounted on the axle (21) of disc support. EFFECT: higher efficiency and reliability. 5 cl, 2 dwg
