Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation equipment technology, specifically to a multi-nozzle spray gun device. Background Technology

[0002] In agricultural and industrial production, irrigation and dust control are crucial for ensuring smooth operations. Sprinklers, as core components of irrigation and dust control equipment, directly impact irrigation and dust removal efficiency. Currently, most sprinklers on the market feature a single nozzle design, allowing for fixed spraying in a single direction. This lack of flexibility in adjusting the spray angle according to actual needs leads to situations where some areas are over-watered while others remain dry, severely hindering crop growth. Similarly, in industrial dust control, the fixed spray angle makes it difficult to precisely target dust sources at different locations, reducing dust removal efficiency.

[0003] Meanwhile, existing sprinklers generally lack effective flow regulation mechanisms, making it impossible to adjust the water flow rate according to different agricultural irrigation targets or industrial dust removal needs. When small-flow, fine irrigation or dust removal is required, it can only be adjusted by controlling the main valve of the water supply pipeline. This method not only has low adjustment accuracy but also easily leads to unstable water pressure throughout the pipeline, affecting the normal operation of other equipment. Furthermore, the single-nozzle design limits the coverage area of ​​the sprinkler head. To achieve large-area irrigation or dust removal, multiple sprinklers need to be installed. This not only increases equipment costs but also causes water waste or incomplete dust removal due to overlapping or gaps in the spray range between sprinklers. Utility Model Content

[0012] Preferably, the main interface tube is provided with external threads, and the main locking nut is connected and fixed to the external threads on the main interface tube.

[0013] Preferably, a plurality of guide plates are provided at the end of the main flow hole away from the main nozzle, and the guide plates are fixed to the main ball head; the extension direction of the guide plates is parallel to the axial direction of the main water spray pipe; the plurality of guide plates are arranged in a circular array with the axis of the main water spray pipe as the center.

[0014] Preferably, the axis of the connecting pipe is parallel to the axis of the main spray pipe; a support ring is installed inside the connecting pipe; one end of the support ring abuts against the flow regulating mechanism, and the other end is provided with a secondary recess structure that cooperates with the secondary ball head, the secondary ball head being rotatably installed in the secondary recess structure; the front end of the secondary nozzle extends through the secondary locking nut to the outside of the secondary locking nut; a secondary guide hole communicating between the secondary nozzle and the support ring is provided inside the secondary ball head.

[0015] Preferably, the connecting pipe is provided with external threads, and the secondary locking nut is connected and fixed to the external threads on the connecting pipe.

[0016] Preferably, the flow regulating mechanism includes a valve core and a knob; the valve core is rotatably installed inside the connecting pipe; the axis of the valve core coincides with the axis of the connecting pipe; a flow guiding channel is provided inside the valve core, connecting the extension pipe and the mounting ring; the flow guiding channel includes a transverse channel and a longitudinal channel; one end of the transverse channel is connected to the support ring; one end of the longitudinal channel is used to connect to the extension pipe; the knob is placed outside the connecting pipe at the end away from the secondary nozzle and is fixedly connected to one end of the valve core, and rotating the knob adjusts the communication state between the longitudinal channel and the extension pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The main ball head in the main nozzle assembly is rotatably mounted in the main recess structure inside the main interface pipe. It works in conjunction with a main locking nut that connects to the external thread of the main interface pipe. Loosening the nut allows the main ball head to rotate and adjust the main nozzle angle, while tightening the nut fixes the angle. This structure allows the main nozzle to flexibly change its spray direction according to the target area for irrigation or dust removal, avoiding coverage blind spots caused by a single fixed angle and meeting the directional spraying needs of different scenarios.

[0020] The main flow orifice inside the main ball head has multiple guide plates arranged in a circular array at the end furthest from the main nozzle, with their extension direction parallel to the axis of the main spray pipe. The guide plates can straighten the water flow entering the main flow orifice, preventing the water flow from scattering at the near end of the sprinkler due to centrifugal force generated by rotation, effectively increasing the spray distance of the main nozzle, further expanding the coverage area of ​​the main spray path, and enhancing the overall sprinkler irrigation or dust removal effect.

[0021] At least one auxiliary water spray pipe connected to the main water spray pipe is fixedly installed on the outer side of the main water spray pipe, and is equipped with a corresponding auxiliary nozzle assembly. The auxiliary ball head in the auxiliary nozzle assembly is rotatably installed in the auxiliary recess structure of the support ring inside the connecting pipe. Combined with the auxiliary locking nut that can be connected to the external thread of the connecting pipe, the angle of the auxiliary nozzle can be flexibly adjusted to specifically cover the spray blind spot of the main nozzle assembly. With the circumferential array distribution of multiple auxiliary water spray pipes, all-round irrigation or dust removal without dead angles can be achieved.

[0022] The auxiliary nozzle assembly's connecting pipe houses a flow regulation mechanism. Its valve core is rotatably mounted within the connecting pipe, and the flow guide channel within the valve core connects to the extension pipe and the support ring. An external knob is fixedly connected to the valve core. Rotating the knob adjusts the connection between the valve core's longitudinal channel and the extension pipe, thereby precisely controlling the water flow rate of the auxiliary nozzle. This structure allows for flow rate adjustment based on the irrigation or dust suppression needs of different areas. For example, the flow rate can be reduced in areas with low water demand to avoid water waste, while the flow rate can be increased in areas with severe dust pollution to improve dust suppression efficiency.

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] like Figures 1 to 9 As shown, a multi-nozzle spray gun device includes:

[0036] The main water spray pipe 2 has a main interface pipe 13 and a secondary interface pipe 1 integrally installed at both ends. The secondary interface pipe 1 is used to connect to the water supply pipeline. At least one secondary water spray pipe 3 is fixedly installed on the outer side of the main water spray pipe 2. The secondary water spray pipe 3 is connected to the main water spray pipe 2.

[0037] The main nozzle assembly, as the main component of sprinkler irrigation, includes a main locking nut 10, a main ball head 11, and a main nozzle 12. One end of the main nozzle 12 is fixed to the main ball head 11. The main ball head 11 is rotatably installed inside the main interface pipe 13. The main locking nut 10 is sleeved on the main ball head 11 and connected to the main interface pipe 13. After the main locking nut 10 is loosened, the main ball head 11 can rotate inside the main interface pipe 13, so that the axis of the main nozzle 12 and the axis of the main interface pipe 13 form a certain angle, so that the water flow sprayed from the main nozzle 12 is adjustable within a certain range.

[0038] The auxiliary nozzle assembly includes an extension pipe 4, a connecting pipe 6, a flow regulating mechanism, an auxiliary locking nut 7, an auxiliary ball head 8, and an auxiliary nozzle 9. One end of the extension pipe 4 is installed on the auxiliary water spray pipe 3, and the other end is fixed to the side of the connecting pipe 6. The flow regulating mechanism is installed inside the connecting pipe 6. One end of the auxiliary nozzle 9 is fixed on the auxiliary ball head 8. The auxiliary ball head 8 is rotatably installed on one end of the connecting pipe 6. The auxiliary locking nut 7 is sleeved on the auxiliary ball head 8 and connected to the connecting pipe 6. The main nozzle 12 and the auxiliary nozzle 9 are connected to the main interface pipe 13. The spray range of the auxiliary nozzle assembly is adjustable and is used to supplement the spraying blind spots of the main nozzle assembly, so that the overall irrigation area is larger and the irrigation is more uniform.

[0039] In this embodiment, the axes of the main water pipe 2 and the auxiliary water pipe 3 are perpendicular; three auxiliary water pipes 3 are arranged in a circular array with the axis of the main water pipe 2 as the center line; the included angle between the axes of two adjacent auxiliary water pipes 3 is 90°; and three auxiliary nozzle assemblies are arranged corresponding to the three auxiliary water pipes 3. This makes the irrigation coverage area wider and achieves spraying without dead angles.

[0040] In this embodiment, the main interface tube 13 is provided with a main recess structure 18 that mates with the main ball head 11, and the main ball head 11 is rotatably installed in the main recess structure 18; the front end of the main nozzle 12 extends through the main locking nut 10 to the outside of the main locking nut 10; the main ball head 11 is provided with a main flow hole 19 that connects the main nozzle 12 and the main interface tube 13.

[0042] In this embodiment, a plurality of guide plates 20 are provided at the end of the main flow orifice 19 away from the main nozzle 12, and the guide plates 20 are fixed on the main ball head 11; the extension direction of the guide plates 20 is parallel to the axial direction of the main water pipe 2; the plurality of guide plates 20 are arranged in a circumferential array with the axis of the main water pipe 2 as the center. The guide plates 20 are used to make the water flow entering the main flow orifice 19 spray out in a straight line, preventing the water flow from being sprayed out in a rotating state, which can avoid the water flow from scattering at the near end of the irrigation under the action of centrifugal force, thereby increasing the spraying distance and making the irrigation coverage area larger.

[0043] In this embodiment, the axis of the connecting pipe 6 is parallel to the axis of the main spray pipe 2; a support ring is installed inside the connecting pipe 6; one end of the support ring abuts against the flow regulating mechanism, and the other end is provided with a secondary recess structure that cooperates with the secondary ball head 8, and the secondary ball head 8 is rotatably installed in the secondary recess structure; the front end of the secondary nozzle 9 extends through the secondary locking nut 7 to the outside of the secondary locking nut 7; a secondary guide hole is provided inside the secondary ball head 8 to connect the secondary nozzle 9 and the support ring.

[0044] In this embodiment, the connecting pipe 6 is provided with external threads, and the secondary locking nut 7 is connected and fixed to the external threads of the connecting pipe 6.

[0045] In this embodiment, the flow regulating mechanism includes a valve core 16 and a knob 5. The valve core 16 is rotatably installed inside the connecting pipe 6. The axis of the valve core 16 coincides with the axis of the connecting pipe 6. Water flows from one side of the valve core 16 through the interior of the valve core 16 and then flows out. This structural design of the valve core 16 can prevent the valve core 16 from being damaged by excessive water pressure. A flow guiding channel is provided inside the valve core 16, connecting the extension pipe 4 and the mounting ring. The flow guiding channel includes a transverse channel 22 and a longitudinal channel 17 that are connected. One end of the transverse channel 22 is connected to the support ring. One end of the longitudinal channel 17 is used to connect to the extension pipe 4. The knob 5 is placed outside the connecting pipe 6 at the end away from the secondary nozzle 9 and is fixedly connected to one end of the valve core 16. Rotating the knob 5 adjusts the connection state between the longitudinal channel 17 and the extension pipe 4. The connecting pipe 6 is externally fixed with a rotation angle limiting structure to limit the rotation angle of the valve core 16. The knob 5 is provided with a rotation angle limiting groove that cooperates with the rotation angle limiting structure. The rotation angle limiting structure can be a limiting rod or a limiting block.

[0046] In this embodiment, a rubber sealing sleeve 15 is fitted onto the outside of the valve core 16; the outer surface of the rubber sealing sleeve 15 is in frictional contact with the inner wall of the connecting pipe 6; a positioning post 21 is fixedly provided on the outer surface of the valve core 16; the rubber sealing sleeve 15 is provided with a first through hole that mates with the longitudinal channel 17 and a second through hole that mates with the positioning post 21, with the positioning post 21 placed inside the second through hole. The rubber sealing sleeve 15 is used to prevent water from flowing out from the gap between the valve core 16 and the connecting pipe 6.

[0047] In this embodiment, the applicable fields of the device include, but are not limited to, farmland irrigation, dust removal equipment, irrigation equipment, sprinkler irrigation equipment, spraying equipment, and environmental protection equipment. It is applicable to all scenarios involving sprinkler irrigation or spraying operations.

[0048] Working principle

[0049] This utility model nozzle achieves wide-area, uniform irrigation or dust removal functions through the logic of "water flow diversion - multi-component coordinated adjustment - precise spraying". Its core consists of three parts: the main spray path mechanism, the secondary spray path mechanism, and the coordinated action of key components, as detailed below:

[0050] 1. Water flow input and diversion logic

[0051] The water supply pipe is directly connected to the auxiliary interface pipe 1 of the sprinkler head. The water flow first enters the auxiliary interface pipe 1, and then splits into two paths to form a dual-spray system:

[0052] Main spray path: Sub-port pipe 1 → Main spray pipe 2 → Main port pipe 13 → Main flow hole 19 of main ball head 11 → Main nozzle 12 → Spray out;

[0053] The water flow path of the auxiliary spray path is as follows: auxiliary interface pipe 1 → main spray pipe 2 → auxiliary spray pipe 3 (a total of 3, arranged in a circular array with the axis of the main spray pipe 2 as the center, with adjacent pipes having an included angle of 90°) → extension pipe 4 → flow regulation mechanism in connecting pipe 6 → support ring → auxiliary guide hole of auxiliary ball head 8 → auxiliary nozzle 9 → spraying out.

[0054] 2. Core Functional Mechanism of the Main Injection Path

[0055] The main jet path is the "main jet component," which achieves long-distance, directional jetting through adjustable angle and stable water flow.

[0056] Angle adjustment: The main ball head 11 can rotate freely through the "main recess structure 18" inside the main interface pipe 13. After loosening the main locking nut 10 connected to the external thread of the main interface pipe 13, rotating the main ball head 11 can change the water spray direction of the main nozzle 12 (such as upward, tilted at 45°, etc.). After adjustment, tighten the main locking nut 10 to fix the angle.

[0057] Flow stabilization and distance increase: The main flow hole 19 of the main ball head 11 is equipped with a "circular array distribution of guide plates 20" (extending direction parallel to the axis of the main water spray pipe 2), which can straighten the incoming water flow into a "straight flow", avoid "near-end scattering" caused by centrifugal force generated by water flow rotation, significantly increase the spray distance, and expand the coverage of the main spray path.

[0058] 3. The core function mechanism of the secondary injection path

[0059] The secondary spray path is a "blind spot adjustment component," which supplements the blind spots of the main spray path through adjustable angle and controllable flow, achieving comprehensive coverage without dead angles.

[0060] Angle adjustment: The secondary ball head 8 can rotate through the "secondary recess structure" in the support ring. After loosening the secondary locking nut 7 connected to the external thread of the connecting pipe 6, the direction of the secondary nozzle 9 can be adjusted by rotating the secondary ball head 8 to specifically cover the edge area that the main nozzle 12 cannot reach. After adjustment, tighten the locking nut to fix it.

[0061] Flow regulation: The flow regulation mechanism (valve core 16 + knob 5) inside the connecting pipe 6 controls the flow: Knob 5 is fixedly connected to valve core 16. Rotating knob 5 can drive valve core 16 to rotate, and the flow is adjusted by changing the "connection area between the longitudinal channel 17 inside valve core 16 and extension pipe 4" (the larger the connection area, the larger the flow; the smaller the area, the smaller the flow; if there is no connection, the secondary spray path is closed); at the same time, the "rotation angle limiting structure" (such as limiting rod / block) of the connecting pipe 6 cooperates with the "limiting groove" of knob 5 to prevent the valve core 16 from being damaged by excessive rotation;

[0062] Leak-proof sealing: The valve core 16 is fitted with a rubber sealing sleeve 15 (positioned by the positioning pin 21, and the rubber sleeve is in frictional contact with the inner wall of the connecting pipe 6), which can completely block water from leaking from the gap between the valve core 16 and the connecting pipe 6, ensuring that all water is delivered to the auxiliary nozzle 9 through the guide channel.

[0063] 4. Overall synergistic effect

[0064] The three auxiliary nozzle assemblies form a "three-dimensional coverage" with the main nozzle assembly: the main spray path is responsible for long-distance, wide-area spraying, while the three auxiliary spray paths (with an angle of 90°) cover the blind spots of the main spray path. Combined with their respective angle and flow rate adjustments, they ultimately achieve a "no dead angle, uniform" irrigation or dust removal effect.

[0065] How to use

[0066] Based on the nozzle's structural design, the usage process consists of four steps: "installation, adjustment, use, and maintenance." It is simple to operate and can be flexibly adapted to various scenarios (agricultural irrigation / industrial dust removal).

[0067] 1. Step 1: Installation and Piping Connection

[0068] Scenario adaptation: Select the application scenario according to the needs (agricultural irrigation: installed on irrigation brackets in the field; industrial dust removal: installed at the end of dust removal pipeline);

[0069] Pipeline connection: Securely connect the external water supply pipeline to the secondary interface pipe 1 of the nozzle. After connection, check whether the interface is sealed (sealant tape can be wrapped around the interface in advance to prevent leakage).

[0070] 2. Second step: Adjust the angle of main nozzle 12 (main spray path)

[0071] Loosen the locking nut: Rotate the main locking nut 10 on the outside of the main interface tube 13 counterclockwise until the main ball head 11 can rotate freely (no need to unscrew it completely to ensure easy tightening later);

[0072] Adjusting the angle: Rotate the main ball head 11 by hand to adjust the main nozzle 12 to the target direction (such as aiming at the crop planting area during agricultural irrigation, or aiming at the dust source during industrial dust removal).

[0073] Locking and fixing: After confirming that the angle is correct, rotate the main locking nut 10 clockwise until it is tightened (to prevent the main ball head 11 from shifting due to water pressure when spraying water).

[0074] 3. Third step: Adjust the angle and flow rate of auxiliary nozzle 9 (blind spot spray path).

[0075] (1) 9-angle adjustment of secondary nozzles (operate separately for each of the 3 secondary spray paths)

[0076] Loosen the secondary locking nut 7: Rotate the secondary locking nut 7 on the outside of the connecting pipe 6 counterclockwise to release the rotation restriction of the secondary ball head 8;

[0077] Blind spot positioning: Observe the water spray blind area of ​​the main nozzle 12 (such as the edge and corner of the spray range of the main nozzle 12), and rotate the secondary ball head 8 to make the secondary nozzle 9 align with the blind area;

[0078] Locking and fixing: Tighten the secondary locking nut 7 clockwise to fix the angle of the secondary nozzle 9.

[0079] (2) Flow regulation of secondary nozzle 9

[0080] Determine the needs: If the blind area requires a large amount of water replenishment / dust removal, increase the flow rate; if only minor adjustments are needed, decrease the flow rate.

[0081] Rotate knob 5: Rotate knob 5 at the end of connecting pipe 6 (on the side away from auxiliary nozzle 9) to change the communication area between longitudinal channel 17 and extension pipe 4 by "rotating valve core 16 driven by knob 5".

[0082] Rotate knob 5 clockwise (refer to the limit groove on knob 5): the connecting area increases → the flow rate increases;

[0083] Rotate knob 5 counterclockwise: the connecting area decreases → the flow rate decreases;

[0084] Rotate until the limit slot engages the limit structure: achieve maximum / minimum flow (or complete closure);

[0085] Test spray confirmation: Turn on the water supply line and let the water flow through slightly. Observe whether the flow rate of the secondary nozzle 9 meets the requirements. If not, adjust it again.

[0086] 4. Fourth step: Use and daily maintenance

[0087] Formal use: After confirming that all adjustments are completed, fully open the water supply pipeline valve, and the nozzle will spray in the set direction and flow rate; if adjustments are needed during use (such as changing the spray height after the crop grows), repeat steps 2-3;

[0088] Maintenance and upkeep:

[0089] After each use, close the valve and check if the rubber sealing sleeve 15 is aging (if leakage occurs, replace it in time);

[0090] Regularly clean impurities (such as mud, sand, and crop residues) from the main flow hole 19, secondary flow hole, and flow guide plate 20 to avoid clogging and affecting spraying;

[0091] Check if the threads of the locking nut are intact. If stripped threads are found, replace the nut promptly to ensure the angle is fixed.
