Description

Drip Spray Double Effect Irrigator and Its Irrigation System

Technical field:

The utility model relates to an agricultural irrigation equipment and system, in particular to an irrigation device and an irrigation system with both drip irrigation and spray irrigation functions.

Background technique:

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 China 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 be used as a drop (water) head to irrigate and fertilize these two requirements at the root.

Utility model content:

The purpose of this utility model is to provide a drip spray double-effect sprinkler. The sprinkler is designed with two kinds of pressure structures, so that the spray irrigation and drip irrigation can be completed in one sprinkler. It can be used as a drop (water) head to irrigate and fertilize the roots. The utility model also provides a drip-spray double-effect irrigation system how to control the drip-spray double-effect sprinkler to realize the above-mentioned functions.

The technical solution to solve the above-mentioned technical problems is: a drip spray double-effect irrigator, including a connecting body with irrigation water inlet, a sprinkler head part composed of a support sleeve, a rotating body and a rotating body bracket located on the upper part of the connecting body, and a nozzle part located at the lower part of the connecting body. The dripper part consisting of a cone joint, an insert rod, a valve core and a spring for changing the flow direction of irrigation water;

The rotating body bracket of the nozzle part and the connecting body are firmly connected by a conical surface. The supporting sleeve is embedded in the rotating body bracket, and the rotating body is sleeved on the supporting sleeve to match it with a small gap; It can rotate freely under the support of the body bracket, and there is a sprinkler water inlet channel in the center of the support sleeve;

The cone joint with the drip irrigation water inlet channel is connected under the connecting body through the screw sleeve with internal and external thread structure, and the insert rod with the drip irrigation water outlet at the bottom is located under the cone joint, and the cone surface between the cone joint and the cone joint is firmly pressed. connect;

The spool is located inside the connecting body and cooperates with its small gap, and can move up and down flexibly. There are two small through holes on the circumference of the spool as throttling wedge grooves, namely: the drip irrigation water inlet channel, and the spring is installed in the inner hole of the screw sleeve. One end is sleeved on the taper joint, and the other end withstands the valve core.

Due to the adoption of the above structure, the beneficial effects of the drip spray double-effect irrigation device and the drip spray double-effect irrigation system of the present invention are:

1. Sprinkler irrigation and drip irrigation can be completed in one emitter at the same time. It can be used as a sprinkler to spray on the leaves of crops, and it can also be used as a drip (water) head to irrigate and fertilize the roots.

The drip-spray double-effect emitter of the utility model adopts a direct plug-in structure, and the irrigation water (with pressure) entering the emitter will be converted by the valve core to its flow direction, and the water inlet pressure is used to control the sliding of the valve core, so that the water flows between the two sides. Switch between two water inlets (spray irrigation and drip irrigation), so as to achieve the purpose of choosing drip irrigation or sprinkler irrigation;

When the system pressure is low, the drip irrigation mode is used, which can drip irrigation to the roots of plants for tall and short crops. Unlike the previous drip irrigation, water drips from the soil surface into the soil, and the water is actually sent to the plant water intake, so that the plants "drink water" instead of Irrigate, reduce water evaporation, and rationally use irrigation water resources.

When the system pressure is high, the mode of sprinkling and micro-spraying is used. During micro-spraying, the inserting rod can be retracted and connected according to the height of the plant growth, which can replenish the water on the plant leaves in time, or spray foliar fertilizers and potions. Very practical and effective.

2. The system has multiple functions: the utility model drip-spray double-effect irrigation system can not only be used as an irrigation system, but also can adjust the working pressure to spray water mist or medicine according to the needs, which is used to adjust the local microclimate and prevent frost.

Below, the technical features of the drip-spray double-effect sprinkler and its irrigation system of the present invention will be further described in conjunction with the accompanying drawings and embodiments.
