Description

Technical Field

[0001] The utility model relates to the technical field of water-saving agriculture, in particular to an atomizing nozzle for water-saving agricultural irrigation. Background Art

[0002] Water-saving irrigation is an irrigation method that maximizes yield or profit with minimal water usage. It aims to maximize crop yield and output value per unit of irrigation water. It primarily includes low-pressure pipe irrigation, sprinkler irrigation, and micro-irrigation. Sprinkler irrigation uses pressure to deliver water to atomizing nozzles, which then spray the water into the air and evenly distribute it over the area in need. Sprinkler irrigation not only effectively covers larger areas and improves irrigation efficiency, but also reduces soil erosion and protects soil structure, making it widely used. Atomizing nozzles, as a key component in sprinkler irrigation, play a vital role.

[0003] Currently, the more commonly used irrigation sprinkler is similar to the one disclosed in Chinese utility model patent CN201621017760.4, which includes a sprinkler body, a connector connected to the sprinkler body, a control valve arranged on the sprinkler body, a diversion port arranged on the sprinkler body, a diversion nozzle movably arranged on the diversion port, a plurality of water spray holes arranged on the diversion nozzle, and a collection tank movably arranged on the diversion nozzle at the connection between the diversion nozzle and the diversion port. However, when the above-mentioned sprinkler is used for water spraying irrigation, water enters the diversion port and is sprayed out from the water spray holes of each diversion nozzle on the diversion port. The water sprayed from the water spray holes is basically a linear water column, and the atomization effect is poor, resulting in poor irrigation uniformity, affecting the irrigation effect, and easily causing waste of water resources. Utility Model Content

[0004] The utility model aims to disclose an atomizing nozzle for water-saving agricultural irrigation, in order to solve the problem that the existing nozzle has poor atomizing effect and causes waste of water resources.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A water-saving agricultural irrigation atomizing nozzle comprises a nozzle body, a vertically arranged water inlet pipe at the top of the nozzle body, a horizontally arranged water distribution pipe connected to the water inlet pipe in the middle, and water distribution branches symmetrically arranged at the left and right ends of the water distribution pipe and connected to the water distribution pipe at the bottom, a first regulating valve being installed on the water distribution branch pipe, and a conical atomizing nozzle being connected to the bottom of the water distribution branch pipe, the atomizing nozzle comprising a water spray nozzle connected to the fluid of the water distribution branch pipe and an air jet nozzle sleeved and fixed on the outside of the water spray nozzle, an air inlet pipe being connected to the side of the air jet nozzle, a second regulating valve being installed on the air inlet pipe, and a central axis of the nozzle of the water spray nozzle coinciding with the central axis of the nozzle of the air jet nozzle.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] First, the dual-atomizing nozzle design increases the sprinkler irrigation range and improves the sprinkler irrigation efficiency; secondly, the design of the water nozzle and the air nozzle achieves a better atomization effect while increasing the range, saving water resources; thirdly, the design of the water diversion tongue can reduce the water hammer effect caused by water inflow and protect the water inlet pipe; finally, by setting up a protective shell, the exterior of the atomizing nozzle is provided with auxiliary outer cover anti-collision protection, which can reduce external damage to the atomizing nozzle assembly.

DETAILED DESCRIPTION

[0012] The present invention will be further explained below with reference to the accompanying drawings.

[0013] like Figure 1-2 As shown, a water-saving agricultural irrigation atomizing nozzle includes a nozzle body 1, the top of the nozzle body 1 is a vertically arranged water inlet pipe 2, the middle is a horizontally arranged water distribution pipe 3 connected to the water inlet pipe 2, and the bottom is a water distribution branch pipe 4 symmetrically arranged at the left and right ends of the water distribution pipe 3 and connected to the water distribution pipe 3. A first regulating valve 10 is installed on the water distribution branch pipe 4, and a conical atomizing nozzle 5 is connected to the bottom of the water distribution branch pipe 4. The atomizing nozzle 5 includes a water nozzle 7 fluidically connected to the water distribution branch pipe 4 and an air nozzle 6 sleeved and fixed on the outside of the water nozzle 7. The side of the air nozzle 6 is connected to the air inlet pipe 8, and the air inlet pipe 8 is installed with a second regulating valve 11. The central axis of the nozzle of the water nozzle 7 coincides with the central axis of the nozzle of the air nozzle 6.

[0014] During use, the water inlet pipe 2 and the air inlet pipe 8 are first connected to the water source and air source of existing agricultural irrigation equipment, respectively. The water and air pressures are then adjusted using the first regulating valve 10 and the second regulating valve 11, ensuring that the air pressure is 1 to 2 times the water pressure. This achieves pressurized atomization and further enhances the dispersion and uniformity of the water spray. The air and water are evenly mixed in the conical atomizing nozzle and then sprayed outward, increasing the range while achieving a better atomization effect and improving irrigation efficiency. Furthermore, both the first regulating valve 10 and the second regulating valve 11 utilize one-way valves to prevent backflow of air and water. The dual atomizing nozzle design disperses the sprayed water to both sides, irrigating a wider area and further improving irrigation effectiveness.

[0015] Furthermore, the water inlet pipe 2 is connected to the middle of the water distribution pipe 3, and a water diversion tongue 9 is vertically provided in the middle of the water distribution pipe 3, which extends upward to the inside of the water inlet pipe 2. The purpose is to protect the water inlet pipe, reduce the water hammer effect, and avoid rupture and water leakage at the connection between the nozzle body and the external water pipe.

[0016] Furthermore, a protective cover 12 is provided on the outside of the nozzle body 1, and the protective cover 12 is fixedly connected to the nozzle body 1 by screws. Figure 2 As shown, fixing seats 13 are provided on either side of the top of the water distribution pipe 3. Connection holes 14 are provided on either side of the top of the protective cover 12. Screws 15 are inserted into the connection holes 14 and threadedly connected to the fixing seats 13. The protective cover 12 adopts a two-half split structure as is conventionally used in the art, wherein the bottom shell is fixedly connected to the nozzle body 1 by screws, and the cover plate is fixedly connected to the bottom shell by snap fasteners.
