Abstract
Description
Technical Field
[0001] This utility model belongs to the field of irrigation rotary sprinkler technology, specifically relating to a rotary sprinkler that provides uniform irrigation. Background Technology
[0002] In agricultural production, irrigation is one of the key factors affecting crop growth and yield. Appropriate irrigation methods can provide crops with sufficient and even water, promoting root development, nutrient absorption, and photosynthesis, thereby improving crop quality and yield.
[0003] With the continuous growth of the global population and the gradual decrease in arable land, improving agricultural water use efficiency and achieving precision irrigation have become essential requirements for sustainable agricultural development. Traditional irrigation methods, such as flood irrigation and furrow irrigation, suffer from serious water waste and uneven irrigation. Rotary sprinklers, as an advanced irrigation device, have advantages such as uniform irrigation, good water-saving effect, and strong adaptability, and have been widely used in agricultural irrigation.
[0004] The development of rotary sprinklers has gone through several stages, from early simple mechanical rotary sprinklers to modern high-tech intelligent rotary sprinklers, with their performance and functions continuously improving. Early rotary sprinklers mainly relied on the reaction force of the water flow to propel the sprinkler head to rotate, spraying water through nozzles on the sprinkler head to achieve large-area irrigation. This type of rotary sprinkler had a simple structure and low cost, but it had certain limitations in terms of irrigation uniformity, spray distance, and coverage.
[0005] Some rotating sprinklers, due to improper nozzle design or uneven water flow distribution within the sprinkler head, result in significant differences in water distribution across different locations within the irrigation area. Some areas may experience over-irrigation, leading to water waste and soil nutrient loss; while other areas may experience under-irrigation, hindering crop growth. This uneven irrigation phenomenon is particularly pronounced in large farmlands and areas with complex terrain. Summary of the Invention

The rotating sprinkler head for uniform irrigation includes a sprinkler head body, a water inlet connector rotatably connected to the bottom of the sprinkler head body, the sprinkler head body is Y-shaped, and two water spray heads are connected to the upper part of the sprinkler head body in a V-shape.
[0010] Below each of the two water nozzles is a beak-shaped nozzle that sprays a flat, misty spray of water, allowing for close-range irrigation.
[0011] Two water nozzles have elliptical nozzles on the sidewalls near the circular nozzles. The thrust generated by the water flowing out of the elliptical nozzles can rotate the main body of the nozzles and provide medium-distance irrigation through the elliptical nozzles.
[0012] The top of each of the two water nozzles is equipped with a circular nozzle for spraying cylindrical water droplets, which allows for long-distance irrigation.
[0013] The spray head is equipped with an adjustment mechanism for adjusting the rotation speed of the spray head body.

Detailed Implementation
[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model. Example
[0032] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the uniformly irrigating rotating sprinkler of this embodiment includes a sprinkler body 1, a water inlet connector 2 rotatably connected to the bottom of the sprinkler body 1, two water nozzles 3 connected in a V-shape at the top of the sprinkler body 1, an eagle beak nozzle 4 for spraying flat mist water droplets is provided below the water nozzles 3, a circular nozzle 31 for spraying cylindrical water droplets is provided at the top of the water nozzles 3, an elliptical nozzle 32 for spraying elliptical flat water droplets is provided on one side of the water nozzles 3, and an adjustment mechanism 5 for adjusting the rotation speed of the sprinkler body 1 is provided on the water nozzles 3.
[0033] This invention proposes a rotating sprinkler head for uniform irrigation. The sprinkler body 1 is the core component of the entire rotating sprinkler head, and the water inlet connector 2 is located at the bottom of the sprinkler body 1 and is rotatably connected to it. This rotatable connection allows the sprinkler body 1 to rotate relative to the water inlet connector 2, which is responsible for introducing water into the sprinkler body 1, providing a water flow channel for subsequent spraying. Two spray heads 3 are connected in a V-shape at the top of the sprinkler body 1. This V-shaped layout helps to expand the spray coverage area, making irrigation more uniform.
[0034] The beak-shaped sprinkler head 4 is located below the sprinkler head 3, specifically on the side wall of the Y-shaped lower vertical part of the sprinkler body 1. Its function is to spray flat, mist-like water droplets. These flat, mist-like water droplets increase the contact area between water and air, resulting in more even water evaporation. They also gently cover the irrigation area, reducing impact on plants. The circular nozzle 31 is located at the top of the sprinkler head 3 and sprays cylindrical water droplets. These cylindrical water droplets provide a concentrated flow, delivering a strong impact and irrigating over a longer distance. The elliptical nozzle 32 is located on one side of the sprinkler head 3 and sprays elliptical, flat water droplets. These elliptical, flat water droplets combine the characteristics of flat and elliptical shapes, creating a relatively uniform water flow coverage with a certain width within a certain range, meeting the needs of irrigation areas of different shapes. The beak-shaped sprinkler head 4 is used for close-range irrigation, such as... Figure 5 As shown in Figure a; medium-distance irrigation is carried out through elliptical nozzles 32, such as... Figure 5 As shown in Figure b; long-distance irrigation is achieved through circular nozzles 31, such as... Figure 5 As shown in c.
[0035] The adjustment mechanism 5 is installed on the sprinkler head 3, and its function is to adjust the rotation speed of the sprinkler head body 1. By adjusting the rotation speed, the coverage area and irrigation intensity of the water spray can be controlled. For example, under a certain water pressure, a faster rotation speed can make the water spray cover a smaller area, but the irrigation time per unit area is relatively shorter; a slower rotation speed can make the water spray more concentrated in a larger area, increasing the irrigation water volume and time per unit area.
[0036] Regarding the elliptical nozzle 32, the reaction force generated during water spraying drives the nozzle body 1 to rotate. The pressurized water sprayed from the side of the nozzle body 1 generates a reaction force, which drives the nozzle body 1 to rotate. The nozzle driven by this reaction force generates a rotational torque due to the relative reaction force. The rotation adjustment mechanism 5 adjusts the water outlet angle of the elliptical nozzle 32, thereby adjusting the magnitude of the rotational torque and thus the rotation speed.
[0037] Combination Figure 1 , Figure 2 and Figure 3As shown, the adjustment mechanism 5 includes a V-shaped tube 51 located at the top of the nozzle body 1. The two ends of the V-shaped tube 51 are threadedly connected to two water nozzles 3. The V-shaped tube 51 has several adjustable scales 52, and a fixed scale 53 is located beside the elliptical nozzle 32. Specifically, the V-shaped tube 51 is located at the top of the nozzle body 1. The two ends of the V-shaped tube 51 are threadedly connected to two water nozzles 3. This ensures the stability of the connection between the V-shaped tube 51 and the nozzles, while also allowing the V-shaped tube 51 to rotate relative to the nozzles to a certain extent, providing a structural basis for subsequent adjustment functions.
[0038] By rotating the V-tube 51 and making precise adjustments with reference to the scale 52 and the fixed scale 53, the working state of the sprinkler head 3 will change accordingly. This adjustment may affect the rotation speed of the sprinkler head, the angle range of the spray, or the water flow distribution of different nozzles, ultimately achieving adjustments to parameters such as irrigation uniformity and irrigation range to meet different irrigation needs.
[0039] Combination Figure 2 , Figure 3 and Figure 4 As shown, the bottom inner wall of the water inlet connector 2 is provided with an internal thread 21. A rotating tube shaft 22 is inserted into the water inlet connector 2, and the top end of the rotating tube shaft 22 is threadedly connected to the bottom of the nozzle body 1. The internal thread 21 is provided on the bottom inner wall of the water inlet connector 2. The internal thread 21 is used to achieve a threaded connection with the external water source pipe, ensuring a firm connection and good sealing to prevent water leakage. The water inlet connector 2 has a cavity inside for the rotating tube shaft 22 to be inserted. The size and shape of the cavity are adapted to the rotating tube shaft 22 to ensure that the rotating tube shaft 22 can be smoothly inserted with a certain amount of room for movement, while also ensuring stability when water flows through.
[0040] The rotating shaft 22 is an intermediate component connecting the water inlet connector 2 and the nozzle body 1. It not only transmits water flow but also allows the nozzle body 1 to rotate relative to the water inlet connector 2, thus enabling the nozzle to rotate and spray water within the irrigation area. The top of the rotating shaft 22 has an external thread that matches the internal thread 21 at the bottom of the nozzle body 1, securing the rotating shaft 22 to the nozzle body 1 via a threaded connection. This threaded connection ensures both the strength of the connection, allowing the rotating shaft 22 to stably support the nozzle body 1 and transmit water flow, and the ability for the nozzle body 1 to rotate relative to the rotating shaft 22, as the threaded connection, while bearing a certain axial force, does not excessively restrict rotational movement.
[0041] The lower part of the rotating tube shaft 22 is inserted into the internal cavity of the water inlet connector 2. This allows the rotating tube shaft 22 to maintain a relatively stable position under the constraint of the water inlet connector 2, without affecting its own rotational function. When water flows through, the insertion structure between the rotating tube shaft 22 and the water inlet connector 2 ensures smooth water transmission and reduces water flow resistance. The outer surface of the water inlet connector 2 is provided with octagonal protrusions 24 for easy identification and tightening by the operator.
[0042] Combination Figure 3 and Figure 4 As shown, a blocking block 221 is provided at the bottom end of the rotating tube shaft 22, which contacts the inner wall of the water inlet connector 2. Several sealing rings 222 are provided between the blocking block 221 and the inner wall of the water inlet connector 2. The blocking block 221 is a structure that protrudes from the bottom surface of the rotating tube shaft 22. It is in direct contact with the inner wall of the water inlet connector 2 and mainly serves to limit the excessive extension of the rotating tube shaft 22 into the water inlet connector 2 and stabilize the position of the rotating tube shaft 22, preventing the rotating tube shaft 22 from undergoing undesirable axial movement within the water inlet connector 2 under the impact of water flow or other external forces.
[0043] The sealing ring 222 is located between the contact point between the blocking block 221 and the inner wall of the water inlet connector 2, that is, it surrounds the blocking block 221 in the area where it contacts the inner wall of the water inlet connector 2. It is evenly distributed on the contact surface between the blocking block 221 and the inner wall of the water inlet connector 2, and plays a sealing role.
[0044] A sealing ring 6 is provided between the spray head 3 and the V-shaped tube 51. The sealing ring 6 fits tightly against the contact surface of the spray head 3 and the V-shaped tube 51, providing a good seal. The spray head body 1, the water inlet connector 2, and the spray head 3 are all made of plastic. Example
[0045] Compared to Example 1, combined with Figure 3 As shown, the top inner wall of the water inlet connector 2 has several equidistant grooves 23 for accommodating small particles such as silt and sand. These grooves 23 are located in the initial flow area after water enters the water inlet connector 2, a place where small particles such as silt and sand easily enter and settle. The equidistant distribution of these grooves 23 helps to more effectively accommodate impurities. The specific shape of the grooves 23 may be semi-circular, square, or other suitable geometric shapes, and their size is designed according to the actual size of the small particles such as silt and sand that may enter, ensuring that a certain amount of impurities can be accommodated without affecting the normal flow of water. Multiple grooves 23 can increase the total area for accommodating impurities, improving the filtration and impurity-accommodating capacity. The presence of the grooves 23 also ensures that accumulated impurities will not affect the rotation of the nozzle, thus extending the product's lifespan.
[0046] When cleaning and maintenance of the water inlet connector 2 is required, the water inlet connector 2 can be removed by disconnecting its connection with related components. Then, impurities in the groove 23 can be removed to ensure that the groove 23 continues to perform its function of containing impurities and maintain the normal operation of the nozzle system.
[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
