Description

Technical Field

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

[0002] A spray gun is a device used for farmland irrigation or industrial dust removal. One end of the gun is connected to a high-pressure water stream, which sprays water out through the nozzle.

[0003] Chinese patent number 201721126773.X discloses a uniform-speed automatic rotating spray gun. This spray gun uses a purely mechanical method, rotating a steering wheel via water flow to achieve uniform rotation and reversal of the entire device, thus providing uniform irrigation in the angular direction. However, during spraying, uneven irrigation still occurs in the radial direction. For example, within the spray gun's range, in the direction away from the spray gun, the water volume per unit area (e.g., within 1 square meter) is relatively high at a distance of 0-3 meters, while at a distance of 3-7 meters, the water volume per unit area drops sharply and is less than that at a distance of more than 7 meters. This uneven irrigation significantly affects the spray gun's performance and fails to meet the requirements for water conservation and high efficiency in irrigation or dust removal.

[0004] Based on the above, there is an urgent need for a water spray gun that can solve the aforementioned technical problems. Utility Model Content

[0037] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] The following reference Figures 1 to 5 This invention introduces the water spray gun provided by this utility model.

[0041] refer to Figure 1 As shown, in this embodiment, the water-crushing spray gun includes a base 1, a spray pipe 2, a steering spray pipe 4, a steering wheel 5, a transmission structure 6, and a water-crushing component 3. The base 1 has a communicating cavity. The spray pipe 2 and the steering spray pipe 4 are mounted on the base 1 and connected to the communicating cavity. Pressurized water enters the spray pipe 2 and the steering spray pipe 4 through the communicating cavity, respectively. The water sprayed from the spray pipe 2 is used for irrigation. The outlet end of the steering spray pipe 4 faces the steering wheel 5, and the third water stream it sprays can impact the steering wheel 5, causing the steering wheel 5 to rotate clockwise or counterclockwise. The steering wheel 5 is driven to the input end of the transmission structure 6, and the output end of the transmission structure 6 is driven to the base 1, so that the rotational kinetic energy of the steering wheel 5 can be transmitted to the base 1 through the transmission structure 6. The base 1 includes an upper base and a lower base. The spray pipe 2 is mounted on the upper base, and the upper base is rotatably connected to the lower base and can rotate under the drive of the transmission structure 6, thereby driving the spray pipe 2 to rotate. The transmission structure 6 has various existing specific configurations, which will not be described in detail in this embodiment.

[0042] In this embodiment, as Figure 2 As shown, the nozzle 2 has a first spray hole 211 at its spray end. The first spray hole 211 can spray a first water flow to irrigate a unit area within the range of the first water flow. Exemplarily, in this embodiment, the maximum range of the first water flow is 0-30m, ensuring a preset irrigation effect (e.g., within 0-30m, the water volume per unit area follows a normal distribution) within a distance of 0-30m from the nozzle 2. Simultaneously, the maximum range of the third water flow, dispersed by the steering wheel 5, is 3m, ensuring a preset irrigation effect (e.g., within 0-3m, the water volume per unit area follows a normal distribution) within a distance of 0-3m from the nozzle 2. However, this configuration results in simultaneous irrigation by both the first and third water flows within 0-3m, leading to a sudden drop in water volume per unit area near 3m, as mentioned in the background section.

[0043] Therefore, in this embodiment, as Figure 2 , Figure 3 As shown, the spray nozzle 2 is also provided with a second spray hole 212 at its spray end, which can spray a second water stream. The water-spraying gun also includes a water-spraying component 3, which is positioned along the spray path of the second water stream. This component reduces the range of the second water stream by blocking some of the water, thus shortening its range. For example, in this embodiment, the maximum range of the second water stream is 15m, ensuring a preset irrigation effect within a distance of 0-15m from the spray nozzle 2 (e.g., within 0-15m, the water volume per unit area follows a normal distribution). This allows for simultaneous irrigation by both the first and second water streams at a distance of 3m. By rationally setting the relative positions of the water-spraying component 3 and the second water stream, a sudden drop in water volume at 3m can be avoided, resulting in a smooth and uniform irrigation effect within 0-30m, meeting the water-saving and high-efficiency requirements in irrigation or dust removal.

[0044] By setting up a water-breaking component 3 and a second water spray hole 212, the water-breaking component 3 adjusts the range of the second water flow, replenishing the water volume in the local water-deficient areas within the range of the existing spray gun. This makes the irrigation effect within the range of the water-breaking spray gun smooth and uniform, avoiding uneven irrigation and meeting the needs of water conservation and high efficiency in irrigation or dust removal operations.

[0045] like Figures 1 to 3 As shown, in this embodiment, the water-breaking component 3 includes a first water-breaking component 31 and a second water-breaking component 32. The first water-breaking component 31 is used to homogenize the irrigation effect of the first water flow, and the second water-breaking component 32 is used to reduce the range of the second water flow and homogenize the irrigation effect of the second water flow.

[0046] Specifically, the first water-breaking component 31 includes a water-breaking rod. One end of the water-breaking rod is positioned on the spray path of the first water flow, while the other end is mounted on the base 1 and connected to the output end of the transmission structure 6. This allows one end of the water-breaking rod to periodically block the first water flow, enabling the first water flow to achieve a relatively uniform irrigation effect within its range. This, in conjunction with the aforementioned second water flow, achieves a smooth and uniform irrigation effect within the range of the water-breaking spray gun.

[0047] Optionally, in this embodiment, the spray nozzle 2 is detachably provided with a nozzle 21 at the spray end of the nozzle 2, and the first spray hole 211 and the second spray hole 212 are provided on the nozzle 21, which facilitates maintenance of the nozzle 21 or the inside of the nozzle 2.

[0048] Preferably, the nozzle 21 includes a first nozzle and a second nozzle, wherein the cross-sectional area of ​​the second water spray hole 212 of the first nozzle is different from the cross-sectional area of ​​the second water spray hole 212 of the second nozzle. By replacing the first nozzle with the second nozzle, the flow rate of the second water flow can be directly controlled, thereby facilitating precise water replenishment to localized water-deficient areas within the range of the existing spray gun.

[0049] Furthermore, in this embodiment, the second water spray hole 212 is arbitrarily positioned on the spray pipe 2 so that the overlap size of the second water fragment 32 and the second water flow is adjustable. This allows for precise water replenishment to localized areas of water shortage within the range of the existing spray gun, and also enables adjustment of the range of the second water flow according to the specific extent of the localized water shortage.

[0050] In this embodiment, the nozzle 21 is installed at an adjustable angle on the nozzle 2 along its axial direction. The second water spray hole 212 is located at the edge of the nozzle 21, and the first water spray hole 211 is located at the center of the nozzle 21. During installation, by rotating the nozzle 21 around the axial direction of the nozzle 2, the overlap size between the second water flow and the second water abrasive element 32 can be changed. It is understood that the larger the overlap size, the stronger the blocking effect of the second water abrasive element 32 on the second water flow, and thus the shorter the range of the second water flow can be limited. For example, along... Figure 3 By rotating the installation angle of the nozzle 21 in the direction of the arrow shown, the overlap between the second water flow and the second water-breaking component 32 can be reduced, and the blocking effect of the second water-breaking component 32 on the second water flow can be weakened.

[0051] Preferably, in this embodiment, such as Figure 4As shown, the second water-breaking component 32 is provided with a water-breaking structure, which includes either a water-breaking recess 321 or a water-breaking protrusion 322. The water-breaking structure is used to disperse the second water flow. The water-breaking recess 321 can be a water-breaking groove, a water-breaking hole, etc., and the water-breaking protrusion 322 can be a cylindrical, prismatic, or polygonal protrusion, etc., solid structure that protrudes from the second water-breaking component 32. In this utility model, the shape of the second water-breaking component 32 and the specific water-breaking structure are not specifically limited. For example, the second water-breaking component 32 can be a simple cylinder or prismatic, or it can be a complex polyhedron with both a water-breaking groove and a polygonal protrusion, etc., as long as it can achieve the effect of blocking and breaking (including atomizing) the second water flow, it falls within the scope of protection of this utility model.

[0052] More preferably, in this embodiment, the second water-breaking component 32 is rotatably disposed, and at least one water-breaking structure is disposed at the edge of the second water-breaking component 32 around its axial direction, so that the water-breaking structure periodically breaks up the water. By rotating the second water-breaking component 32, the water-breaking structure and the second water flow repeatedly switch between overlapping and non-overlapping states, which can further improve the uniformity of the water-breaking effect, thereby providing more uniform water replenishment to local water-deficient areas within the range of the existing spray gun, thus achieving a smooth and uniform irrigation effect within the range of the water-breaking spray gun.

[0053] Specifically, in this embodiment, the second water-crushing component 32 is tractively connected to the steering wheel 5, and the steering wheel 5 drives the second water-crushing component 32 to rotate. Exemplarily, in some embodiments, the second water-crushing component 32 is fixedly connected to the steering wheel 5. Optionally, in this embodiment, as... Figure 5 As shown, the second water-crushing component 32 has a mounting hole 323, which can be fixedly connected to the input end of the transmission structure 6 (e.g., connected to the input shaft of the transmission structure 6) in a sleeve manner. By connecting the steering wheel 5 through the transmission, the second water-crushing component 32 can be driven and controlled to rotate and crush water in a purely mechanical manner. This not only eliminates uneven irrigation but also avoids various problems caused by electric drive, such as short circuits, difficulty in maintenance, and the need for a power supply. Furthermore, by using a transmission method such as an eccentric wheel, the rotation of the second water-crushing component 32 can be adjusted within a cycle, resulting in a better irrigation effect.

[0054] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
