Description

Technical Field

[0001] This invention belongs to the field of irrigation sprinkler technology, and more specifically, relates to an energy-saving irrigation sprinkler for strawberry cultivation. Background Technology

[0002] During strawberry cultivation, continuous irrigation is necessary to ensure normal growth and development. Currently, drip irrigation is commonly used to irrigate strawberry plants, as it avoids water spraying onto the fruit and affecting fruit quality. This method offers the following advantages:

[0003] 1. Drip irrigation systems can precisely control water flow and irrigation time, delivering water directly to the soil near plant roots, reducing water evaporation loss and surface runoff, thus significantly improving water resource utilization efficiency.

[0004] 2. Drip irrigation systems typically require less energy to propel water, thus saving energy consumption, especially when the pump needs to run for extended periods, resulting in significant energy savings.

[0005] 3. Drip irrigation systems deliver water directly to the vicinity of plant roots, rather than spraying it across the entire plant surface, thus reducing the likelihood of pests and diseases spreading between plants and contributing to plant health management.

[0006] However, the following problems may occur when using irrigation sprinklers to irrigate strawberries:

[0007] 1. In traditional drip irrigation systems, it is usually necessary to adjust or shut down the entire water pipe as a whole, rather than precisely controlling the water flow from a single sprinkler head. This method is inconvenient or impossible to implement when it is necessary to shut down or adjust a single sprinkler head at a specific point.

[0008] 2. In existing irrigation sprinkler designs, it is often difficult to shut down a single sprinkler without affecting the normal operation of other sprinklers, or to maintain the stability and durability of the system while adjusting the water flow;

[0009] 3. Existing irrigation sprinklers are complex to operate when switching between multiple states or making precise adjustments, and there may be instability after the state is adjusted, resulting in unreliable irrigation effects or the need for frequent maintenance and adjustments.

[0010] Against this backdrop, the present invention proposes an energy-saving strawberry irrigation sprinkler head. This sprinkler head adopts an innovative structure and design, which can achieve precise water control under different working conditions, thereby achieving the goal of saving energy. Summary of the Invention

[0011] To address the aforementioned technical problems, this invention provides an energy-saving strawberry irrigation sprinkler head.

[0012] An energy-saving strawberry irrigation sprinkler includes a main sprinkler pipe and two connecting pipes. The main sprinkler pipe has two connecting grooves in its middle section. A drip irrigation sprinkler is installed at the rear end of the main sprinkler pipe. A plug-in limiting component is installed on the outer wall of the main sprinkler pipe, including two sleeves and two deflection rods. An adjustment component is installed inside the main sprinkler pipe, including a push-pull rod. A sealing limiting component is installed at the opening of the main sprinkler pipe away from the drip irrigation sprinkler, including an installation ring, a perforated plate, and two finger sleeves. A circular ring is fixedly fitted at the end of the main sprinkler pipe closest to the drip irrigation sprinkler. The main sprinkler pipe and the drip irrigation sprinkler are threaded together. A sealing ring is placed between the connection points of the main sprinkler pipe and the drip irrigation sprinkler. The two connecting pipes are fixedly fitted into the two connecting grooves respectively.

[0013] Preferably, each of the two sleeves has a round hole, and a thin sleeve is movably fitted into each of the two round holes. A limit ring and a connecting piece are fixed at both ends of the thin sleeve, and a spring is provided inside the thin sleeve. The two ends of the spring are fixedly connected to the connecting piece and the inner wall of the sleeve near the nozzle main pipe.

[0014] Preferably, each deflector has a central groove in the middle part, the two central grooves are rotatably connected to two connecting pieces respectively, and each deflector has a locking block fixedly connected to both ends, and the two deflectors are respectively attached to two sleeves.

[0015] Preferably, a piston and a push-pull plate are fixedly connected to both ends of the push-pull rod, and annular grooves are provided in the middle part and both ends of the push-pull rod, wherein the piston is sleeved inside the nozzle main pipe.

[0016] Preferably, a perforated plate 1 and two sleeve blocks are fixedly connected to the mounting ring. Slots are passed through the upper and lower ends of the mounting ring. The perforated plate 2 fits into the mounting ring. Two connecting ears are fixedly connected to the perforated plate 2. Each connecting ear has a pair of short rods fixedly connected to the side facing the mounting ring, and a pair of long rods fixedly connected to the side facing away from the mounting ring. A triangular limiting block is fixed to the end of each short rod and long rod.

[0017] Preferably, each finger sleeve is fixedly connected to a slide rod, the two slide rods are movably connected to two slots respectively, and a second spring is movably connected to each slide rod. A semi-circular ring is fixedly connected to the near ends of the two slide rods. A baffle is also fixedly connected to each of the two slide rods, and the second spring is located between the baffle and the inner wall of the mounting ring.

[0018] Preferably, when both finger sleeves are in contact with the outer wall of the mounting ring, the complete ring formed by the two semi-circular rings is locked in the annular groove at the corresponding position.

[0019] Preferably, the lateral length of the short rod is the same as the lateral length of the sleeve block, and the lateral length of the long rod is equal to the lateral length of the sleeve strip.

[0020] Preferably, a sealing ring is fixed at the slot of the perforated plate, and a groove adapted to the sealing ring is opened in the middle part of the push-pull plate.

[0021] Preferably, a rubber ring is fixed along the front end of the nozzle main tube.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In this invention, two hoses are respectively fitted onto two connecting pipes. The operator moves two finger sleeves to release the restriction on the push-pull rod, thereby changing the position of the piston in the nozzle main pipe. Three states can be switched: completely blocking the water source, blocking the water source of the nozzle alone, and normal use state.

[0024] In this invention, the hose is restricted by the tapered end of the connecting tube, and the connection between the hose and the connecting tube will be thickened. Then, the tightening screw is rotated to make the inner wall of the tightening screw squeeze the thickened part of the connecting tube, which achieves the effect of auxiliary fixation, making it difficult for the hose and the connecting tube to separate after connection. The friction between the inner wall of the hose and the outer wall of the connecting tube, combined with the friction between the outer wall of the hose and the inner wall of the tightening screw, achieves the effect of double friction limit.

[0025] In this invention, the operator inserts their thumb and middle finger into two finger sleeves to control the separation of the two finger sleeves, thereby moving the semi-circular ring clip out of the annular groove. Then, by pulling the push-pull plate, the position of the piston is moved, releasing the finger sleeves. Under the elastic force of the second spring, the semi-circular ring clip re-clamps into the corresponding annular groove. When the semi-circular ring clip is in the annular groove at the front end, the piston blocks the rear end of the nozzle main pipe, without affecting the normal flow of water between the two hoses, thus not affecting other nozzles. This achieves the effect of shutting off a specific drip irrigation nozzle without affecting other nozzles. When the semi-circular ring clip is in the annular groove in the middle, the piston blocks the connecting groove, preventing the connection between the two hoses and blocking the entire water flow. When the semi-circular ring clip is in the annular groove at the rear end, the piston does not act as an obstruction, and the entire nozzle is in normal working condition. Switching between the three states is convenient and the operation is simple. Furthermore, because the semi-circular ring clip is clamped in the annular groove, the three states are not easily changed after adjustment, exhibiting good stability.

[0026] In this invention, by pulling the deflection rod, the locking block on the deflection rod is disengaged from the two short rods and the two long rods. Then, by pinching the two long rods together, the triangular limiting blocks on the two long rods are brought close together and can pass through the sleeve, achieving the effect of quickly separating the nozzle main tube and the perforated plate II, which facilitates cleaning the inside of the nozzle main tube and replacing the entire adjustment assembly.

[0027] In this invention, by pinching the two short rods together, the triangular limiting blocks on the short rods approach each other and can be separated by the sleeve block, so that the perforated plate two can separate the mounting ring, thereby exposing the inside of the mounting ring and facilitating cleaning of the inside of the mounting ring. The perforated plate two connects the mounting ring and the nozzle main pipe at the same time, optimizing the structure. The thin sleeve is located between the two long rods and will not hinder the sliding of the long rods. Attached Figure Description

[0037] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0038] Please see Figures 1-8This invention provides an energy-saving strawberry irrigation sprinkler head, comprising a main sprinkler head 1 and two connecting pipes 21. The main sprinkler head 1 has two connecting grooves 8 in its middle section. A drip irrigation sprinkler head 4 is installed at the rear end of the main sprinkler head 1. A plug-in limiting component is installed on the outer wall of the main sprinkler head 1, including two sleeves 9 and two deflection rods 15. An adjustment component is provided inside the main sprinkler head 1, including a push-pull rod 17. A sealing limiting component is installed at the opening of the main sprinkler head 1 away from the drip irrigation sprinkler head 4, including an installation ring 22, a perforated plate 27, and two finger sleeves 26. A circular ring 7 is fixedly fitted at the end of the main sprinkler head 1 closest to the drip irrigation sprinkler head 4. The main sprinkler head 1 and the drip irrigation sprinkler head 4 are threaded together, and a sealing gasket is placed between the connection points of the main sprinkler head 1 and the drip irrigation sprinkler head 4. Ring 20, two connecting pipes 21 are fixedly sleeved with two connecting grooves 8 respectively. The opposite ends of the two connecting pipes 21 are tapered ends, and the middle part of the two connecting pipes 21 is a threaded section. The middle part of the two connecting pipes 21 is threaded with a fastening screw tube 5. The opposite ends of the two connecting pipes 21 are sleeved with water conveying hoses 6. The hoses 6 are restricted by the tapered ends on the connecting pipes 21. The connection between the hoses 6 and the connecting pipes 21 will be thickened. Then, the fastening screw tube 5 is rotated so that the inner wall of the fastening screw tube 5 squeezes the thickened part of the connecting pipe 21, achieving the effect of auxiliary fixation. This makes it difficult for the hoses 6 and the connecting pipes 21 to separate after connection. The friction between the inner wall of the hose 6 and the outer wall of the connecting pipe 21, combined with the friction between the outer wall of the hose 6 and the inner wall of the fastening screw tube 5, achieves the effect of double friction limiting.

[0039] Both sleeves 9 have round holes 10, and each round hole 10 has a thin sleeve 14 movably fitted inside. The two ends of the thin sleeve 14 are fixed with a limit ring 34 and a connecting piece 13, respectively. The thin sleeve 14 has a spring 11 inside. The two ends of the spring 11 are fixedly connected to the connecting piece 13 and the inner wall of the sleeve 9 near the nozzle main pipe 1, respectively. Each deflection rod 15 has a middle groove 12 in the middle part. The two middle grooves 12 are rotatably connected to the two connecting pieces 13, respectively. Each end of each deflection rod 15 is fixedly connected with a locking block 16. The two deflection rods 15 are respectively attached to the two sleeves 9.

[0040] The push-pull rod 17 has pistons 19 and push-pull plates 3 fixedly connected to its two ends, respectively. The middle part and both ends of the push-pull rod 17 have annular grooves 18. The piston 19 is fitted inside the nozzle main pipe 1. A perforated plate 2 and two sleeve blocks 33 are fixedly connected to the mounting ring 22. Slots 23 pass through the upper and lower ends of the mounting ring 22. A perforated plate 27 fits into the mounting ring 22. Two connecting ears 28 are fixedly connected to the perforated plate 27. Each connecting ear 28 has a pair of short rods 30 fixedly connected to the side facing the mounting ring 22. Each connecting ear 28 is positioned away from the mounting ring 22. A pair of long rods 29 are fixedly connected to each surface of the mounting ring 22. A triangular limiting block is fixed to the end of each short rod 30 and the long rod 29. A sliding rod 25 is fixedly connected to each finger sleeve 26. The two sliding rods 25 are movably connected to the two slots 23 respectively. A second spring 24 is movably connected to each sliding rod 25. A semi-circular ring clip 32 is fixedly connected to the near ends of the two sliding rods 25. A baffle 31 is also fixedly connected to each of the two sliding rods 25. The second spring 24 is located between the baffle 31 and the inner wall of the mounting ring 22. The long rods 29 and the short rods 30 are both elastic rods.

[0041] By pulling the deflection rod 15, the locking block 16 on the deflection rod 15 is disengaged from the two short rods 30 and the two long rods 29. Then, by pinching the two long rods 29, the triangular limiting blocks on the two long rods 29 are brought close together and can pass through the sleeve 9, achieving the effect of quickly separating the nozzle main tube 1 and the perforated plate 27. This facilitates cleaning the inside of the nozzle main tube 1 and replacing the entire adjustment assembly. When both finger sleeves 26 are in contact with the outer wall of the mounting ring 22, the complete ring body formed by the two semi-circular rings 32 is locked in the annular groove 18 at the corresponding position. The lateral length of the short rod 30 is the same as the lateral length of the sleeve 33, and the lateral length of the long rod 29 is equal to the lateral length of the sleeve 9. A sealing ring is fixed at the groove of the perforated plate 2. The middle part of the push-pull plate 3 has a groove that matches the sealing ring. A rubber ring is fixed along the front end of the nozzle main tube 1. The operator uses his thumb and middle finger to insert into the two finger sleeves 26 to control the separation of the two finger sleeves 26, thereby moving the semi-circular rings 32. Disengage from the annular groove 18, then pull the push-pull plate 3 to move the position of the piston 19, release the finger sleeve 26, and under the elastic force of the spring 24, the semi-circular ring clip 32 re-clamps into the corresponding position of the annular groove 18. When the semi-circular ring clip 32 is clamped in the annular groove 18 at the front end, the piston 18 blocks the rear end of the nozzle main pipe 1, without affecting the normal flow of water between the two hoses 6, and thus will not affect other nozzles. This achieves the effect of shutting off a specific drip irrigation nozzle 4 without affecting other nozzles. When the semi-circular ring clip 32 is clamped in the annular groove 18 in the middle, the piston 19 blocks the connecting groove 8, so that the two hoses 6 are no longer connected, thus blocking the entire water flow. When the semi-circular ring clip 32 is clamped in the annular groove 18 at the rear end, the piston 19 does not play a blocking role, and the entire nozzle is in normal working condition. The three states are easy to switch and simple to operate. Moreover, because the semi-circular ring clip 32 is clamped in the annular groove 18, the three states are not easily changed after adjustment, and it has good stability.

[0042] Working principle: When in use, the two hoses 6 are respectively fitted onto the two connecting pipes 21. The operator moves the two finger sleeves 26 to release the restriction on the push-pull rod 17, thereby changing the position of the piston 19 in the nozzle main pipe 1. Three states can be switched: completely blocking the water source, blocking the water source of the nozzle alone, and normal use state.

[0043] The hose 6 is restricted by the tapered end of the connecting tube 21. The connection between the hose 6 and the connecting tube 21 will be thickened. Then, the fastening screw tube 5 is rotated so that the inner wall of the fastening screw tube 5 squeezes the thickened part of the connecting tube 21, which achieves the effect of auxiliary fixation. This makes it difficult for the hose 6 and the connecting tube 21 to separate after connection. The friction between the inner wall of the hose 6 and the outer wall of the connecting tube 21, combined with the friction between the outer wall of the hose 6 and the inner wall of the fastening screw tube 5, achieves the effect of double friction limit.

[0044] The operator inserts their thumb and middle finger into the two finger sleeves 26 to control their separation, thereby moving the semi-circular ring clip 32 out of the annular groove 18. Then, by pulling the push-pull plate 3, the position of the piston 19 is moved, releasing the finger sleeves 26. Under the elastic force of the spring 24, the semi-circular ring clip 32 re-engages into the corresponding position of the annular groove 18. When the semi-circular ring clip 32 is engaged in the annular groove 18 at the very front, the piston 18 blocks the rear end of the nozzle main pipe 1, without affecting the normal water flow between the two hoses 6, thus not affecting other nozzles and achieving a constant flow. Closing one drip irrigation nozzle 4 does not affect the effect of other nozzles. When the semi-circular ring clip 32 is stuck in the middle annular groove 18, the piston 19 blocks the connecting groove 8, so that the two hoses 6 are no longer connected, thus blocking the entire water flow. When the semi-circular ring clip 32 is stuck in the rear annular groove 18, the piston 19 does not play a blocking role, and the entire nozzle is in normal working condition. The three states are easy to switch and simple to operate. Moreover, since the semi-circular ring clip 32 is stuck in the annular groove 18, the three states are not easily changed after adjustment, and it has good stability.

[0045] By pulling the deflection rod 15, the locking block 16 on the deflection rod 15 is disengaged from the two short rods 30 and the two long rods 29. Then, by pinching the two long rods 29, the triangular limiting blocks on the two long rods 29 are brought close together and can pass through the sleeve 9, thus achieving the effect of quickly separating the nozzle main tube 1 and the perforated plate 27, which facilitates cleaning the inside of the nozzle main tube 1 and replacing the entire adjustment assembly.

[0046] By pinching the two short rods 30 together, the triangular limiting blocks on the short rods 30 approach each other and can be separated from the mounting ring 22 by the sleeve block 33, thereby exposing the inside of the mounting ring 22 and facilitating cleaning of the inside of the mounting ring 22. The perforated piece 27 connects the mounting ring 22 and the nozzle main pipe 1 at the same time, optimizing the structure. The thin sleeve 14 is located between the two long rods 29 and will not hinder the sliding of the long rods 29.

[0047] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
