MULTIBARRELLED SPRINKLER UNIT |
摘要 |
FIELD: agriculture.SUBSTANCE: multibarrelled sprinkler unit comprises a lid with the supply pipe equipped with barrels-jet nozzles located along the circle and made at an angle to its surface. On the lid five barrels are placed as follows: two upper barrels are mounted threadedly at an angle of 45° to the horizon and deflected from the axial line of the supply pipe by the angle of 5-6°; two middle barrels are mounted threadedly at an angle of 30-35° to the horizon and deflected from the axial line of the supply pipe by the angle of 15-20°; the lower barrel is mounted with a thread at an angle of 20-25° to the horizon and directed along the axial line of the supply pipe. In the inner cavity of the barrels the screw guides with left-coiling are made. Distribution of irrigation areas from the barrels depends on the pressure in the supply pipe and range of throw S of jet, which is determined from the equationwhere Vis jet exit velocity from the barrel; ? is the angle of installation of the barrel to the horizon; h is the installation height of the barrel above the soil surface; g is acceleration of gravity.EFFECT: increased efficiency of irrigation water use, increased productivity.3 dwg |
