Description

Technical Field

[0001] This utility model relates to the field of crop sprinkler irrigation technology, and in particular to a water sprayer and sprinkler gun. Background Technology

[0002] A spray gun is a device that uses pressure to atomize or spray water onto the surface of crops to achieve irrigation. In traditional sprinkler irrigation equipment, especially large sprinkler machines, the spray guns are usually located in the middle or rear section of the equipment. However, near the main shaft or near the end of the equipment, due to insufficient coverage of the nozzles, "irrigation dead zones" or "spraying blind spots" are often formed.

[0003] Utility model patent CN221157225U discloses a technical solution for a "near-end sprinkler and irrigation gun," including a main connecting pipe seat, a secondary connecting pipe seat, and a nozzle assembly. The nozzle assembly includes a nozzle body with a blind-hole bushing structure. The orifice end of the nozzle body is coaxially and tightly connected to the pipe end of the secondary connecting pipe seat via a sealing ring. The nozzle body is axially positioned relative to the pipe end of the secondary connecting pipe seat and is circumferentially rotatable. A nozzle body rotation angle locking structure is also provided between the nozzle body and the pipe end of the secondary connecting pipe seat. A nozzle orifice communicating with the inner cavity of the blind hole of the nozzle body is provided on the cylindrical outer surface of the nozzle body. This structure achieves a tight connection with the pressure gauge mounting seat on the irrigation gun through the mounting structure at the bottom of the main connecting pipe seat. While effectively replenishing water to the near-end area of ​​the irrigation gun, it is also beneficial to adjust the irrigation range according to operational needs and improve the overall spray uniformity. However, this structure has certain limitations. The spraying range of the nozzle body is mainly concentrated in the circumferential area at the orifice end, and the spraying angle and coverage area are limited, so there may still be spray dead zones; and it is difficult to adapt to different crop irrigation scenarios.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Please refer to Figures 1 to 4 As shown, this embodiment provides a water sprayer, including a first connecting pipe 1, a second connecting pipe 2, and at least two nozzle assemblies 3. The inlet end of the first connecting pipe 1 is used for a sealed connection with an external water supply device. The second connecting pipe 2 is sealed and connected through the first connecting pipe 1 and is provided with at least two outlets. Each nozzle assembly 3 includes an adapter pipe 31, a universal adjustment component 32, and a nozzle 33. The first end of each adapter pipe 31 is detachably and sealed to each outlet of the second connecting pipe 2. The second end of each adapter pipe 31 is connected to the universal adjustment component 32, which can freely adjust the spray angle in multiple directions. The nozzle 33 is installed at the outlet end of the universal adjustment component 32 and is used to spray water in a directional manner to the target area.

[0033] The first connecting pipe 1 serves as the water inlet pipe, sealingly connected to the external water supply equipment. The second connecting pipe 2 is horizontally positioned and runs through the first connecting pipe 1, featuring multiple outlets. This effectively distributes a single water flow into multiple branches, allowing multiple nozzle assemblies 3 to operate simultaneously for multi-point spraying. Each adapter pipe 31 has its first end detachably and sealed to the outlet of the second connecting pipe 2, enabling the nozzle assembly 3's position and height to be freely adjusted before spraying based on crop type, spraying height, and space constraints, improving adaptability. A universal adjustment component 32 is installed between the adapter pipe 31 and the nozzle 33 of the nozzle assembly 3, allowing the nozzle 33 to freely adjust its spray angle in multiple directions. Each nozzle 33 can also have its spray angle adjusted individually, ensuring precise water coverage of the target area and avoiding spray dead zones.

[0034] Optionally, the universal adjustment component 32 is detachably and sealed to the adapter pipe 31 to facilitate the maintenance and replacement of the universal adjustment component 32.

[0035] like Figure 4 As shown, specifically, the universal adjustment component 32 includes a ball joint 321 and a ball 322. The second end of the adapter pipe 31 is provided with an external thread, and one end of the ball joint 321 is provided with an internal thread. The adapter pipe 31 and the ball joint 321 are connected by a threaded seal. The ball joint 321 has a spherical cavity that matches the ball 322. The ball 322 can be rotated in multiple directions and placed in the spherical cavity. The ball 322 has a water passage hole inside, which is connected to the adapter pipe 31. The water outlet end of the water passage hole is fixedly connected to a nozzle 33. The ball 322 can rotate in any direction within the ball joint 321, which makes the angle adjustment of the nozzle 33 more free, accurately covers the target area, and meets the spraying needs of various angles.

[0036] In other embodiments, the universal adjustment component 32 includes a rotating shaft, a swing shaft, and a connector. The rotating shaft is rotatably mounted on the second end of the adapter pipe 31, and the connector is sleeved on the rotating shaft and connected to the swing shaft. Both ends of the swing shaft pass through the connector, and one end is connected to the nozzle 33. The swing shaft can adjust the pitch angle of the nozzle 33. In this dual-axis universal adjustment structure, the rotating shaft can drive the nozzle 33 to rotate left and right, and the swing shaft can drive the nozzle 33 to pitch up and down, which can precisely control the spraying direction and make the operation intuitive.

[0037] like Figure 3 As shown, in some embodiments, the nozzle 33 is a flat nozzle. The nozzle opening of the flat nozzle is flat and elongated, and the width of the flat nozzle gradually increases along the spray direction. This makes the shape of the spray from the nozzle 33 fan-shaped, forming an expanded water flow outlet. The flat outlet can expand the original columnar water flow into a wide and thin fan-shaped water flow. Compared with the columnar water flow, the fan-shaped water flow has a wider and more uniform coverage area, improving the water resource utilization rate.

[0038] To further improve the coverage area of ​​the water sprayer, in some embodiments, the adapter pipe 31 is set at an angle relative to the axis of the second connecting pipe 2, and the connecting pipe can rotate around the axis of the second connecting pipe 2. Since there is an angle between the adapter pipe 31 and the second connecting pipe 2, and the adapter pipe 31 can rotate around the axis of the second connecting pipe 2, a conical or annular spray trajectory is formed. With the help of the universal adapter, the coverage area of ​​the water sprayer can be further expanded and the spray dead zones can be reduced. Furthermore, the adapter pipe 31 can be replaced with a suitable one according to actual needs, improving applicability.

[0039] Combination Figures 1 to 3 As shown, optionally, the adapter pipe 31 is L-shaped, wherein the L-shaped adapter pipe 31 makes the outlet direction of the nozzle 33 perpendicular to or at a certain angle to the direction of the main water supply pipeline, which is conducive to the nozzle 33 obtaining a wider spraying field of view and range, avoiding the nozzle 33 from being blocked or colliding with the main pipeline or other components, and reducing interference between the nozzle 33 and the pipeline.

[0040] For example, for tall crops such as corn, sorghum, and sugarcane, as the crops grow, the length of the L-shaped adapter pipe 31 can be flexibly adjusted by replacing it with different lengths, thereby adapting to the height of the crops at different growth stages and ensuring that the spraying position and angle of the water sprinkler always match the actual needs of the crops.

[0041] To facilitate the rotation and disassembly of the adapter pipe 31, in some embodiments, the first end of the adapter pipe 31 is provided with an external thread, and the outlet of the second connecting pipe 2 is provided with an internal thread, and the adapter pipe 31 and the second connecting pipe 2 are threadedly connected; wherein, the threaded connection makes the installation and disassembly of the adapter pipe 31 and the second connecting pipe 2 simple and quick, and facilitates maintenance, replacement or adjustment of the position of the nozzle 33; and the threaded connection also allows the adapter pipe 31 to be rotated and adjusted in the connected state, flexibly adjusting the orientation of the nozzle 33 and improving the freedom of the spray angle.

[0042] To improve sealing, a seal is provided between the first end of the adapter pipe 31 and the second connecting pipe 2; and / or a seal is provided between the second end of the adapter pipe 31 and the universal adjustment component 32; this can effectively prevent water leakage between structures, ensure the sealing of the connection and the stable operation of the water sprayer.

[0043] Optionally, the seal may be, but is not limited to, an O-ring; no specific limitation is made here. The material of the seal may be, but is not limited to, silicone rings, etc.; no specific limitation is made here.

[0044] This embodiment also provides a sprinkler gun, including the sprinkler and water tank of any of the above embodiments, wherein the water inlet end of the first connecting pipe 1 is sealed to the water tank.

[0045] This sprinkler gun has a wide spray angle and a broader coverage area, effectively avoiding spray dead zones and possessing good adaptability, making it suitable for the irrigation needs of different crops.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
