Drip irrigation is the most effective water-saving irrigation mode in arid water-deficient areas at present, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The irrigation system is suitable for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops in arid places with water shortage.
At present, drip irrigation can only be used for watering and fertilizing downwards, and in the actual use process, a large amount of foliar fertilizer application and foliar spray insecticidal operation needs exist. When the foliar fertilizer or the foliar spray is applied to kill insects, a spraying device needs to be additionally arranged, so that the investment cost is increased. In addition, the existing pesticide spraying device generally sprays from top to bottom, and pesticide spraying is generally sprayed on the upper part of the leaf surface but cannot be sprayed on the lower part of the leaf surface, so that the insecticidal effect is influenced.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
A drip irrigation device with a medicine spraying function, comprising: a pressurizing station, a plurality of adjustable nozzles and pipelines,
the plurality of adjustable nozzles are arranged on a pipeline, and the pipeline is connected with the pressurizing station;
the adjustable nozzle comprises a water pipe, a nozzle pipe and a nozzle cap, the adjustable nozzle is arranged on the pipeline through the water pipe, and the nozzle pipe is arranged on the water pipe and is communicated with the interior of the water pipe;
the inner diameter of the nozzle pipe is smaller than that of the water pipe, the end, connected with the nozzle cap, of the nozzle pipe is processed into a cone, external threads are processed on the side wall of the nozzle pipe, the end, connected with the nozzle pipe, of the nozzle cap is a stepped cavity, the primary cavity is conical and is matched with the conical end of the nozzle pipe, and internal threads are processed on the inner wall of the secondary cavity and are matched with the external threads;
the middle part of the nozzle cap is provided with a nozzle which is in a flaring structure.
In some embodiments, the ratio of the inner diameter of the nozzle tube to the inner diameter of the water tube is 1: 8-15.
The inner diameter of the nozzle pipe is smaller than that of the water pipe, when liquid flowing through the water pipe flows into the nozzle pipe again, the pressure is increased and the flow speed is accelerated due to the fact that the flow area is reduced, the pressure inside the liquid is rapidly reduced after the liquid flows through the nozzle cap, and the liquid is sprayed out in a mist form.
In some embodiments, the ratio of the diameter of the small diameter end to the large diameter end of the nozzle is 1: 1.5-3. To improve the degree of atomisation of the liquid.
In some embodiments, the ratio of the outer diameter to the inner diameter of the nozzle tube is 5-10: 1.
Furthermore, the ratio of the length of the threaded connection section of the nozzle pipe and the nozzle cap to the inner diameter of the nozzle pipe is 2-10: 1.
The outer diameter of the nozzle pipe and the length of the threaded connection section are both far larger than the inner diameter of the nozzle pipe, and when the nozzle cap is screwed out, a cavity between the nozzle cap and the nozzle pipe is enough for depressurizing and decelerating liquid sprayed out of the nozzle pipe, so that the liquid is sprayed out of the nozzle cap in a water column mode.
In some embodiments, a necking diversion structure is arranged at the joint of the nozzle pipe and the water pipe.
The necking diversion structure can make the liquid in the water pipe flow into the nozzle pipe more stably.
In some embodiments, the tapered configuration of the end of the nozzle tube is the same shape and size as the conical primary cavity of the nozzle cap. When the threaded connection of the nozzle pipe and the nozzle cap is completely screwed to the bottom, the nozzle pipe is completely contacted with the nozzle cap, and liquid sprayed out of the nozzle pipe is directly sprayed out of the nozzle cap, so that the atomization degree is improved.
In some embodiments, the pressurizing station comprises a water tank, a pressurizing pump and a valve, wherein an inlet of the pressurizing pump is connected with the water tank through a pipeline, an outlet of the pressurizing pump is connected with the pipeline, and the valve is arranged on the pipeline.
On the premise of not adjusting the power of the pressure pump, the liquid pressure in the pipeline can be adjusted by controlling the opening of the valve, so that the spraying state is adjusted.
In some embodiments, the water pipe is connected with the pipeline through a two-way pipe.

The nozzle cap 2-1 is rotated, when the nozzle cap 2-1 is far away from the nozzle pipe, a cavity is formed between the nozzle cap 2-1 and the nozzle pipe 2-2, liquid pressurized by the nozzle pipe 2-2 firstly enters the cavity, the internal pressure of the liquid is reduced, and the liquid is gushed out in a liquid column form, so that the irrigation operation is realized. The nozzle cap 2-1 is rotated, when the nozzle cap 2-1 is close to the nozzle pipe, the cavity between the nozzle cap 2-1 and the nozzle pipe 2-2 is reduced, the diameter of the liquid pressurized by the nozzle pipe 2-2 is sprayed out through the flaring of the nozzle cap 2-1, the internal pressure of the liquid is rapidly reduced, and the liquid is sprayed out in a mist form, so that the spraying operation is realized.
The pressure adjusting method of the liquid in the pipeline has three ways, namely, the rotating speed of a pressure pump can be controlled to realize water pressure adjustment; secondly, adjusting the valves 1 to 5 and adjusting the internal pressure of the pipelines 1 to 4; thirdly, adjusting the nozzle cap 2-1 to realize the water pressure adjustment of the water outlet. The three can be used in cooperation according to actual conditions.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
