A combined-type, fixable and movable double-purpose sprinkling
irrigation system with double
branch pipes comprises a pump unit, a main
pipe,
branch control valves,
branch pipes, multiple groups of double-branch-
pipe nozzle assemblies combined four-way valves and core plugs, wherein each group of double-branch-
pipe nozzle assembly comprises symmetrically-arranged double branch pipes and two nozzles; the main pipe is connected with the pump unit; the branch
control valves are arranged at the inlets of the branch pipes; and the double branch pipes are connected to the branch pipes through the four-way valves. The pipes are rigid plastic pipes or plastic-coated hoses, and each four-way valve is formed by staggered connection of two three-way valves through a quick connector. During
assembly of the
system, the main pipe and the branch pipes are arranged at first, then the double-branch-pipe
nozzle assemblies are connected; and during moving, the combined four-way valves are unscrewed, and the double-branch-pipe nozzle assemblies can move simultaneously, or the main pipe and the branch pipes are fixed on the ground, other components can be moved.
Nozzle space in the
system is changeable, so that rectangle and triangle spraying can be realized easily; the system is high in suitability of
terrain and crops; in the system, the branch pipes are used for dividing flow, the main pipe laying length is increased, and the development of the unit form is facilitated; and the system can be used in spraying and micro
irrigation with high uniformity.
