[0001] The invention relates to the technical field of irrigation, and in particular to a water spraying structure of a sprinkler. Background Art

[0002] In agricultural production, sprinklers, as important irrigation equipment, play an important role in improving crop yield and quality. However, traditional sprinklers have some problems in the spraying process, such as uneven spraying, limited coverage, and inability to adapt to different terrains and crop requirements. These problems not only affect the irrigation effect, but also waste water resources.

[0003] In addition, with the continuous development of agricultural technology, people have also begun to try to add pesticide spraying functions to sprinklers to meet the needs of crop pest control, etc. However, how to achieve accurate delivery of pesticides and avoid waste while ensuring the spraying effect is still an important challenge faced in the current research and development of sprinklers. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, an object of the present invention is to provide a water spraying structure of a sprinkler, which can realize the functions of increasing the spraying area and automatically adding medicine.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a water spraying structure of a sprinkler, comprising: A fixed pipe, the fixed pipe is fixed to and communicated with a spray branch pipe on the sprinkler; A rotating head and a supporting body, wherein the rotating head is mounted on a fixed tube and can rotate freely on the fixed tube, an axial hole communicating with the fixed tube is arranged inside the rotating head, and the supporting body is fixedly mounted above the rotating head; A first nozzle and a second nozzle, wherein the first nozzle and the second nozzle are respectively mounted on the side walls of the rotating head, the first nozzle and the second nozzle are both connected to the axial hole inside the rotating head, the spraying direction of the first nozzle is obliquely upward on the longitudinal plane, the spraying direction of the second nozzle is horizontally arranged, and the liquid sprayed by the second nozzle can generate sufficient impact force to drive the rotating head to rotate.

[0006] A water pressure plate is rotatably mounted on one side of the rotating head, the rotating surface of the water pressure plate coincides with the spray angle of the first nozzle, and the water pressure plate has an overlapping portion with the spray position of the first nozzle in a natural state. When the water pressure plate contacts the water column sprayed by the first nozzle, the water pressure plate can exert a downward impact force on the water column, causing the water column to spray toward the bottom.

[0007] Preferably, a medicine supply device is fixed to the upper end of the support body, and a jet channel is provided inside the water pressure plate, and the jet channel is connected to the medicine supply device through a hose. A yield plate is slidably installed inside the water pressure plate through a second spring, and the yield plate can seal the jet channel in a natural state. When the water pressure plate is in a natural state, the contact position between the water pressure plate and the water column sprayed by the first nozzle is set on the yield plate.

[0008] Preferably, the drug supply device includes a drug storage tube, a piston plate is slidably mounted inside the drug storage tube via a first spring, a sliding rod is fixed on the piston plate, the sliding rod extends from the end of the drug storage tube to the outside of the drug storage tube, a drug cavity is provided inside the drug storage tube, and a drug injection tube is provided on one side of the medicine cavity.

[0009] Preferably, a buffer column is slidably mounted on one side of the support body close to the water pressure plate via a third spring, and the buffer column extends to the outside of the support body and is movably connected to the water pressure plate.

[0010] Preferably, an arc-shaped spray channel is provided inside the second spray head, and there is a distance between the section corresponding to the water outlet position of the arc-shaped spray channel and the axial hole inside the rotating head.

[0011] Preferably, the water pressure plate is hinged on the support body through a hinge shaft.

[0012] Preferably, a limiting plate is fixed to the bottom of the support body close to the water pressure plate, and when the water pressure plate is in a natural state, the water pressure plate rests on the limiting plate.

[0013] Preferably, the end of the fixing tube away from the rotating head is provided with a threaded head.

[0014] Preferably, a sleeve is fixed to the end of the rotating head, the sleeve is inserted into the interior of the fixed tube, the sleeve and the fixed tube are rotatably connected via a bearing, and a sealing ring is provided at the connection portion between the sleeve and the fixed tube.

[0015] The beneficial effects of the present invention are: The first nozzle and the second nozzle cooperate with each other to ensure efficient and comprehensive spraying. The first nozzle can achieve 360-degree circulation spraying, which not only ensures that the liquid evenly covers a wider area, but also greatly improves the uniformity of spraying. The second nozzle focuses on fine spraying at a closer position. The liquid it sprays has sufficient impact force, which can not only achieve fine spraying, but also drive the entire rotating head to rotate.

[0016] The design of the water pressure plate further improves the flexibility and coverage of the spraying. It is connected to the support body through a hinged shaft and can rotate freely relative to the support body, so as to adjust the spray angle according to actual needs. When the first nozzle starts working, the water column it sprays will contact the water pressure plate. At this time, the water pressure plate will exert a downward force on the water column, changing its spray direction and spraying it towards the bottom. In this way, not only the spraying area is significantly increased, but the vacuum area of ​​the spray is also reduced accordingly, making the spraying effect better.

[0017] In addition, the sprinkler also has a medicine supply function, which is connected to the injection channel inside the water pressure plate, so that the medicine can be sprayed out while spraying the liquid. This design not only increases the versatility of the sprinkler, but also makes the spraying operation more flexible and diverse, which can meet the needs of different users.

DETAILED DESCRIPTION

[0026] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0027] Embodiment 1 like Figure 1-Figure 7 As shown, in this embodiment, a water spraying structure of a sprinkler is provided, comprising a fixed pipe 1, a rotating head 17, a support body 3, a first spray head 4, a second spray head 5 and a water pressure plate 6.

[0028] The fixed pipe 1 is fixed to and connected with the spray branch pipe on the sprinkler. The spray branch pipe is a pipe connecting the sprinkler head and the main structure of the sprinkler, which is responsible for transporting water from the water source to the sprinkler head. The fixed pipe 1 is installed at the water outlet on the spray branch pipe to support the entire water spray structure. The end of the fixed pipe 1 away from the rotating head 17 is provided with a threaded head 7, so that the fixed pipe 1 can be easily connected and disassembled with other components (such as water pipes, sprinklers, etc.).

[0029] The swivel head 17 is installed on the fixed tube 1. The swivel head 17 can rotate freely on the fixed tube 1. The interior of the swivel head 17 is provided with an axial hole connected to the fixed tube 1. The swivel head 17 itself does not have the function of automatic rotation, and additional power is required to drive it to rotate. The support body 3 is fixedly installed above the swivel head 17. A sleeve 20 is fixed to the end of the swivel head 17. The sleeve 20 is plugged into the interior of the fixed tube 1. The sleeve 20 and the fixed tube 1 are rotatably connected through a bearing 19, and a sealing ring 18 is provided at the connection between the sleeve 20 and the fixed tube 1. The bearing 19 is used to support the fixed tube 1 and the swivel head 17 to ensure that the swivel head 17 can rotate freely. The bearing 19 is a commonly used component in the prior art, so the present invention will not be specifically explained. The sealing ring 18 has a sealing effect to prevent liquid from seeping out.

[0030] The first nozzle 4 and the second nozzle 5 are respectively mounted on the side wall of the rotating head 17. The first nozzle 4 and the second nozzle 5 are both connected to the shaft hole inside the rotating head 17. Both nozzles can obtain the liquid to be sprayed through the shaft hole. The spray direction of the first nozzle 4 is obliquely upward on the longitudinal plane. When the liquid is injected and passes through the first nozzle 4, it will spray upward at a certain angle. This spraying method can increase the longitudinal coverage area. The spray direction of the second nozzle 5 is set horizontally, and the liquid sprayed by the second nozzle 5 can generate enough impact force to drive the rotating head 17 to rotate. The interior of the second nozzle 5 is provided with an arc-shaped spray channel. There is a distance between the section corresponding to the outlet position of the arc-shaped spray channel and the shaft hole inside the rotating head 17, so as to ensure that the liquid sprayed from the second nozzle 5 can exert an oblique driving force on the rotating head 17 to rotate the rotating head 17. When the rotating head 17 starts to rotate, it interacts with the liquid sprayed by the first nozzle 4. This interaction not only drives the rotating head 17 to rotate, but also enables the first nozzle 4 to realize self-rotation while spraying liquid. In this way, the first nozzle 4 can complete a 360-degree circulation spraying, ensuring that the liquid can evenly cover a wider area. At the same time, the second nozzle 5 is also continuously spraying liquid, and its spraying direction is aimed at a closer position to achieve fine spraying of these areas. Through this design, the first nozzle 4 and the second nozzle 5 work together to complete a comprehensive and detailed spraying task, ensuring the efficient and uniform spraying effect.

[0031] The water pressure plate 6 is rotatably mounted on one side of the rotating head 17. The water pressure plate 6 is hinged on the support body 3 through a hinge shaft. The water pressure plate 6 can rotate relative to the support body 3, so as to more flexibly adapt to the spraying requirements of different angles and directions. The rotating surface of the water pressure plate 6 coincides with the spraying angle of the first nozzle 4. The water pressure plate 6 has a coincident position with the spraying position of the first nozzle 4 in a natural state. When the water pressure plate 6 contacts the water column sprayed by the first nozzle 4, the water pressure plate 6 can exert a downward impact force on the water column, so that the water column sprays toward the bottom. When the first nozzle 4 starts to work, the water column sprayed by it will immediately contact the water pressure plate 6. As the water column contacts the water pressure plate 6, the water pressure plate 6 exerts a downward impact force on the water column by using its rotation characteristics. This impact force changes the original spraying direction of the water column, so that it is no longer just sprayed upward or obliquely upward, but is effectively guided to spray toward the bottom. This change expands the spraying range, especially covering the bottom and lower positions more comprehensively.

[0032] A limit plate 23 is fixed to the bottom of the support body 3 near the water pressure plate 6. When the water pressure plate 6 is in a natural state, the water pressure plate 6 abuts against the limit plate 23, which helps to limit the movement range of the water pressure plate 6 and prevent the water pressure plate 6 from excessive movement or falling off in an uncontrolled situation. When the water pressure plate 6 is impacted by the water column and moves, the limit plate 23 will play a blocking role and limit the movement range of the water pressure plate 6.

[0033] Embodiment 2 like Figure 1-Figure 7 As shown, based on the first embodiment, this embodiment provides a medicine supply function of the water pressure plate 6, which is as follows: A medicine supply device is fixed at the upper end of the support body 3, and a jet channel 16 is provided inside the water pressure plate 6. The jet channel 16 is connected to the medicine supply device through a hose 8. A clearance plate 15 is slidably installed inside the water pressure plate 6 through a second spring 14. The clearance plate 15 can seal the jet channel 16 in a natural state. When the water pressure plate 6 is in a natural state, the contact position between the water pressure plate 6 and the water column sprayed by the first nozzle 4 is set on the clearance plate 15. The clearance plate 15 will seal the jet channel 16 in a natural state (i.e., when there is no external force), preventing the medicine from flowing out uncontrolled. When the rotating head 17 drives the water pressure plate 6 to rotate, and the water pressure plate 6 contacts the water column sprayed by the first nozzle 4, this contact position is just set on the clearance plate 15. The impact force of the water column will act on the clearance plate 15, overcome the elastic force of the second spring 14, and cause the clearance plate 15 to displace, thereby temporarily opening the seal of the jet channel 16.

[0034] Once the clearance plate 15 is pushed open by the water column, the medicine in the medicine supply device will enter the injection channel 16 through the hose 8 and then be sprayed out through the opening on the water pressure plate 6 (formed by the displacement of the clearance plate 15).

[0035] The spraying direction of the medicine, the rotation direction of the water pressure plate 6 and the impact force of the water column work together to achieve directional spraying of the medicine. When the impact force of the water column weakens or disappears (for example, when the water pressure plate 6 continues to rotate and leaves the spraying range of the first nozzle 4), the second spring 14 will return to its original state and push the yield plate 15 to reseal the injection channel 16. In this way, the spraying process will stop until the next time the water pressure plate 6 contacts the water column again and repeats the above process.

[0036] Embodiment 3 like Figure 1-Figure 7 As shown, based on the first and second embodiments, this embodiment provides a structure of a medicine supply device, which is as follows: The medicine supply device includes a medicine storage tube 2, a piston plate 12 is slidably mounted inside the medicine storage tube 2 through a first spring 11, a slide bar 10 is fixed on the piston plate 12, and the slide bar 10 extends from the end of the medicine storage tube 2 to the outside of the medicine storage tube 2, a medicine cavity 13 is arranged inside the medicine storage tube 2, and a medicine injection tube 9 is arranged on one side of the medicine cavity 13. The piston plate 12 is kept in a relatively fixed position under the action of the spring, thereby closing one end of the medicine cavity 13. The medicine injection tube 9 is used to inject medicine into the medicine cavity 13.

[0037] When it is necessary to add medicine to the medicine supply device, the medicine can be injected into the medicine cavity 13 through the medicine injection tube 9, and a one-way valve is provided inside the medicine injection tube 9. Due to the presence of the piston plate 12, the medicine will be restricted in the medicine cavity 13 and will not flow out at will.

[0038] When the medicine needs to be released, the slide bar 10 can be operated to move away from the medicine storage tube 2. As the piston plate 12 moves, the medicine in the medicine chamber 13 is squeezed by the piston plate 12, generating outward pressure. Once the pressure inside the medicine is large enough and the external hose 8 has been opened (for example, connected to the injection channel 16 of the water pressure plate 6), the medicine will start to flow out.

[0039] When the medicine is completely released, the first spring 11 returns to its original state.

[0040] A buffer column 22 is slidably installed on one side of the support body 3 close to the water pressure plate 6 through a third spring 21. The buffer column 22 extends to the outside of the support body 3 and is movably connected to the water pressure plate 6. When the water pressure plate 6 is impacted by the water column, the buffer column 22 can absorb part of the impact force, reduce the direct collision between the water pressure plate 6 and the support body 3, and extend the service life of the equipment.

[0041] As the impact force weakens, the third spring 21 gradually returns to its original state, pushing the buffer column 22 and the water pressure plate 6 back to their original positions, preparing for the next impact.

[0042] Working principle: When the sprinkler starts to work, water is transported to the fixed pipe 1 through the spray branch pipe, and then supplied to the first sprinkler head 4 and the second sprinkler head 5 through the axial hole inside the rotating head 17.

[0043] The first nozzle 4 sprays liquid upward at a certain angle to increase the longitudinal coverage area; the second nozzle 5 sprays liquid horizontally and generates sufficient impact force to drive the rotating head 17 to rotate; when the rotating head 17 rotates, it interacts with the liquid sprayed by the first nozzle 4, driving the rotating head 17 to rotate, and at the same time the first nozzle 4 realizes self-rotation to complete 360-degree circulation spraying.

[0044] The water pressure plate 6 is rotatably mounted on one side of the rotating head 17. When the first nozzle 4 starts to work, the water column sprayed by it immediately contacts the water pressure plate 6. The water pressure plate 6 exerts a downward impact force on the water column, changing the original spray direction of the water column, making it spray toward the bottom, and expanding the spray range. When the water pressure plate 6 contacts the water column sprayed by the first nozzle 4, the impact force of the water column acts on the clearance plate 15, overcoming the elastic force of the second spring 14, causing the clearance plate 15 to move, and opening the seal of the injection channel 16.

[0045] The medicine in the medicine supply device enters the injection channel 16 through the hose 8 and is sprayed out through the opening on the water pressure plate 6 to achieve directional spraying of the medicine. When the impact force of the water column weakens or disappears, the second spring 14 returns to its original state, pushes the yield plate 15 to reseal the injection channel 16, and stops the injection of the medicine. When the water pressure plate 6 is impacted by the water column, the buffer column 22 absorbs part of the impact force to reduce the direct collision between the water pressure plate 6 and the support body 3. As the impact force weakens, the third spring 21 gradually returns to its original state, pushing the buffer column 22 and the water pressure plate 6 back to their original positions to prepare for the next impact.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
