Combined-type, fixable and movable double-purpose sprinkling irrigation system with double branch pipes

Abstract

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.

Description

technical field [0001] The invention relates to a sprinkler micro-irrigation system in the fields of farmland, gardens, water delivery, etc., in particular to a combined double-branch pipe fixed-moving dual-purpose sprinkler irrigation system with variable nozzle spacing. Background technique [0002] Pipeline sprinkler irrigation systems are divided into three categories: fixed, semi-fixed and mobile. The fixed system has a large amount of pipes and high investment, and is suitable for perennial economic crop irrigation; semi-fixed and mobile sprinkler irrigation systems are widely used in field crops, and most of the moving parts are manually moved. Light and small mobile sprinkler irrigation units are widely used in my country because of their low cost, flexible maneuverability, and strong adaptability to terrain and crops. However, with the transfer of rural labor force in recent years, the gradual development of moderate-scale operations, the changing of crop seasons, ...

AI Technical Summary

Problems solved by technology

However, with the transfer of rural labor force in recent years, the gradual development of moderate-scale operations, the need for changing crop seasons and emergency drought relief, the shortcomings of light and small sprinkler irrigation machines with large mobile labor requirements have become increasingly prominent.

[0003] Mobile sprinkler irrigation systems generally adopt a "one"-shaped, Feng-shaped or comb-shaped arrangement. The two sides of the nozzle standpipe are directly connected to the pipeline, which makes it difficult to adjust the distance between the nozzles in time according to field factors such as outdoor wind speed, wind direction, and crop row spacing. Irregular plots or corners, the nozzle is also difficult to adapt

In hilly areas or intercropping of crops, the working pressure of nozzles in different plots is different or the irrigation quota of crops is different, so different nozzles need to be used, and flexible configuration is required; for the irrigation area of ​​about 50 mu, and multiple irrigations are required in the same irrigation season In some occasions, the pipe network should be fixed during the irrigation season, and the pipes should be removed when the crops are harvested or when the stubble is changed. If a fully mobile irrigation unit is used, the mobile operation will take a long time

[0004] The installation and movement of light and small mobile sprinkler irrigation units is time-consuming and labor-intensive, and the distance between nozzles is difficult to adjust according to field application conditions. In hilly areas or intercropping of crops, sprinklers must be flexibly configured, and the fixed moving time of pipelines is not easy to allocate.

[0005] After searching, there is currently no patent application for the combined double-branch fixed-moving dual-purpose sprinkler irrigation system
