Dripping and spraying double-effect emitter and irrigation system thereof

Abstract

The invention relates to a dripping and spraying double-effect emitter which comprises a connector, a shower nozzle part, a dripper part, a valve core and a spring, wherein the connector is provided with an irrigation water inlet; the shower nozzle part is arranged at the upper part of the connector and comprises a supporting sleeve, a rotating body and a rotating body support; the dripper part is arranged at the lower part of the connector and comprises a cone joint and an insert bar, and the valve core is used for converting the flow direction of pressure water; a firm conical-surface compressing connection is adopted between the rotating body support and the connector; the supporting sleeve is embedded in the rotating body support; the rotating body is sleeved on the supporting sleeve and in small-clearance fit with the rotating body; the rotating body can freely rotate with the support of the supporting sleeve and the rotating body support; a spray irrigation water inlet hole is arranged in the center of the supporting sleeve; the valve core is provided with a drip irrigation water inlet; the cone joint which is internally provided with a drip irrigation water passage is connected below the connector by a thread sleeve with inside and outside thread structures; the insert bar which is provided with a drip irrigation water outlet at the lower part is arranged below the cone joint and in the conical-surface compressing joint with the cone joint; and the emitter ensures that the spray irrigation and the drip irrigation are finished in one emitter by adopting the design of two pressure structures.

Description

Technical field: [0001] The invention relates to an agricultural irrigation equipment and system, in particular to an irrigation device with both drip irrigation and spray irrigation functions and an irrigation system thereof. Background technique: [0002] Drip irrigation technology is recognized as an energy-saving and effective irrigation method, and it is being vigorously promoted in most water-deficient areas. At present, most drip irrigation uses fixed-point drip irrigation on plants; because many areas in southern my country are subtropical areas , the water quality in water resources is high in calcium, and the climate characteristics cause the vigorous growth of moss and algae in the water source, which can easily block the water delivery device, resulting in uneven irrigation and affecting plant growth; at the same time, plants facing the hot sun in the south not only need water for their roots , the leaf surface also needs water to moisten, and most of the sprinkler...

Problems solved by technology

[0002] Drip irrigation technology is recognized as an energy-saving and effective irrigation method, and it is being vigorously promoted in most water-deficient areas. At present, most drip irrigation uses fixed-point drip irrigation on plants; because many areas in southern my country are subtropical areas , the water quality in water resources is high in calcium, and the climate characteristics cause the vigorous growth of moss and algae in the water source, which can easily block the water delivery device, resulting in uneven irrigation and affecting plant growth; at the same time, plants facing the hot sun in the south not only need water for their roots , the leaf surface also needs water to moisten, and most of the sprinkler (water) heads and drip (water) heads on the market that are compatible with sprinkler irrigation or drip irrigation are single-function, and it is difficult to satisfy both spraying on the crop leaf surface as a sprinkler head, It can also be used as a drip (water) head to irrigate and fertilize the roots.
