[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0038] Embodiment 1:

[0039] like Figures 1 to 7 As shown, a vegetable planting irrigation device includes a plurality of spray pipes 1.

[0040] A sleeve 32 is slidably mounted on each spray pipe 1, an adjusting pipe 33 is plugged into the sleeve 32, and a nozzle 34 is rotatably mounted on the top of the adjusting pipe 33; the plug-in design of the adjusting pipe 33 and the sleeve 32 not only facilitates the installation and disassembly of the adjusting pipe 33, and is beneficial to the maintenance and component replacement of the equipment, but also ensures the stability of the structure during the adjustment process. The nozzle 34 is rotatably mounted so that it can perform spraying operations at different angles, greatly increasing the flexibility of the irrigation coverage range.

[0041] A shifting assembly for driving the horizontal displacement of the nozzle 34 is installed in each spray pipe 1. The shifting assembly includes an adjusting roller 2 with a cam groove 21, and the cam groove 21 is interconnected with the sleeve 32. The unique contour design of the cam groove 21, in conjunction with the rotation of the adjusting roller 2, can accurately guide the moving trajectory of the sleeve 32, thereby realizing regular reciprocating displacement of the nozzle 34 in the horizontal direction, effectively avoiding dead corners during the irrigation process, ensuring that every part of the vegetable planting field can be evenly irrigated, and creating good conditions for the balanced growth of vegetables.

[0042] The regulating pipe 33 is provided with an adjusting assembly, which includes a lifting groove 362 which is provided below the spray pipe 1 and is in an inclined state, and the lifting groove 362 is used to change the height of the spray head 34;

[0043] The regulating tube 33 is provided with a control component for controlling the water flow rate according to the height. The control component includes a conical inner cavity 331 opened inside the regulating tube 33 and a blocking block 332 located inside. When the height of the regulating tube 33 rises, the gap between the conical inner cavity 331 and the blocking block 332 gradually increases, the water flow can pass more smoothly, and the flow rate increases accordingly. On the contrary, when the height drops, the gap decreases, the water flow is hindered more, and the flow rate decreases. This method of automatically adjusting the water flow rate according to the height can avoid impact damage to vegetables with a smaller water flow rate when the nozzle 34 is low; and when the nozzle 34 is high, the water flow rate is increased to ensure the expansion of the irrigation range, ensure the irrigation effect, and realize the rational use of water resources during the irrigation process.

[0044] Each spray pipe 1 is provided with a flip assembly, which includes a guide block 4 with the same inclination as the lifting groove 362, and a wave groove 41 is opened on the guide block 4, and the wave groove 41 is used to change the angle of the spray head 34.

[0045] like Figures 1 to 7As shown, in a specific embodiment, flanges 111 are installed at both ends of each spray pipe 1, and the two opposite ends of each spray pipe 1 are connected to each other through a connecting pipe 11. The design of the flange 111 facilitates the rapid connection and disassembly between the spray pipes 1, and can significantly improve work efficiency during equipment installation, maintenance, and flexible adjustment according to different planting field layouts. A notch 14 is opened at the top of each spray pipe 1, and the sleeve 32 is inserted into the notch 14. Such a structural design not only ensures the smooth sliding of the sleeve 32 on the spray pipe 1, but also effectively prevents water from leaking from the connection between the sleeve 32 and the spray pipe 1.

[0046] like Figures 1 to 7 As shown, further, a vertical plate 12 is installed at the bottom of each spray pipe 1, and a base 121 is installed at the bottom of the vertical plate 12. Four corners of the base 121 are provided with mounting holes 122, which facilitate the device to be fixed on the ground by bolts and other connectors, thereby enhancing the stability of the device during operation. A reinforcing rib 123 is installed on the side wall of the base 121, and the side wall of the reinforcing rib 123 is installed on the side wall of the vertical plate 12. The vertical plate 12 is triangular, and the triangular structure has extremely high stability, which can provide a stable support for the entire irrigation device, ensuring that the device will not shake or tip over due to external forces during the irrigation process.

[0047] Embodiment 2:

[0048] The difference between Example 1 and this Example is that: Figures 1 to 7 As shown, a synchronous shaft 22 is installed through the rotation center of the adjusting roller 2, a positioning seat 221 is rotatably installed at the end of the synchronous shaft 22, and the positioning seat 221 is welded to the side wall of the corresponding spray pipe 1. A fan blade 222 is installed at the other end of the synchronous shaft 22, and a deflector 13 is installed inside the spray pipe 1, and the deflector 13 and the fan blade 222 correspond to each other. The deflector 13 can guide the water flow so that it impacts the fan blade 222 in a more concentrated and more effective way, thereby improving the efficiency of the fan blade 222 in converting the kinetic energy of the water into rotational power. This method of using the energy of the water flow itself to drive the synchronous shaft 22 to rotate does not require additional electricity or power equipment, greatly saves energy consumption, and reduces irrigation costs.

[0049] like Figures 1 to 7 As shown, in a specific embodiment, a slide bar 211 is slidably provided on the cam groove 21, a positioning frame 334 is installed on the top of the slide bar 211, a sealing plate 3 is installed on the positioning frame 334, and the sealing plate 3 slides on the inner wall of the spray pipe 1, the sealing plate 3 and the sleeve 32 are connected to each other, a vertical rod 333 is installed on the positioning frame 334, the top of the vertical rod 333 is connected to the blocking block 332, and the diameter of the blocking block 332 is smaller than the diameter of the conical inner cavity 331.

[0050] like Figures 1 to 7As shown, further, a slide plate 31 is installed on the side wall of the sealing plate 3, and a guide rod 311 is movably installed inside the slide plate 31. Fixed seats 313 are installed at both ends of the guide rod 311. The fixed seats 313 are welded to the bottom of the spray pipe 1, and a force storage spring 312 is sleeved on the guide rod 311. One end of the force storage spring 312 is clamped on the guide rod 311, and the other end of the force storage spring 312 is clamped on the fixed seat 313. When the sealing plate 3 slides back and forth, the slide plate 31 on the side wall of the sealing plate 3 also slides in the guide rod 311, providing a stable guiding effect for its movement, so that the moving direction of the sealing plate 3 always remains accurate, avoiding deviation or shaking, thereby ensuring the stability and accuracy of the nozzle 34 during the horizontal displacement process. When the sealing plate 3 slides, the sealing plate 3 can compress the force storage spring 312, so when the sealing plate 3 needs to be reset, the elastic potential energy stored in the force storage spring 312 can be released, so that the sealing plate 3 can quickly and smoothly return to the initial position after the water flow stops driving, and prepare for the next working cycle, thereby extending the service life of the device.

[0051] like Figures 1 to 7 As shown, further, a limit block 353 is installed on the side wall of the sleeve 32, and a limit rod 351 is installed inside the limit block 353, and a support seat 35 is installed on the top of the limit rod 351, and the support seat 35 is installed on the side wall of the adjustment tube 33, and a limit plate 352 is installed on the bottom of the limit rod 351. A limit spring 354 is sleeved on the limit rod 351, and one end of the limit spring 354 is clamped on the limit plate 352, and the other end of the limit spring 354 is clamped on the limit block 353. When the adjustment tube 33 slides on the sleeve 32, the limit block 353 on the side wall of the sleeve 32 slides on the limit rod 351, and the limit rod 351 limits the moving direction of the limit block 353, thereby ensuring the stability and safety of the device during operation, avoiding damage or failure of the device due to excessive movement of components, and facilitating the reset operation later through the limit spring 354.

[0052] Embodiment 3:

[0053] The difference between Example 2 and this example is that: Figures 1 to 7 As shown, a pair of mutually parallel lifting grooves 362 are provided at the bottom of the vertical plate 12, a protrusion 361 is slidably provided inside the lifting groove 362, a synchronous bracket 36 is installed on the side wall of the protrusion 361, and the top of the synchronous bracket 36 is installed on the side wall of the adjustment tube 33. The design of the mutually parallel lifting grooves 362 can more stably lift the adjustment tube 33, ensuring the stability and accuracy of the adjustment tube 33 during the height adjustment process.

[0054] like Figures 1 to 7As shown, in a specific embodiment, a top rod 42 is vertically and movably inserted inside the synchronous bracket 36, the bottom of the top rod 42 is chamfered, and the bottom of the top rod 42 is slidably connected to the wave groove 41, a synchronous rod 421 is installed on the top of the top rod 42, and a swing arm 43 is slidably provided on the side wall of the synchronous rod 421, and the rotation center of the swing arm 43 is interconnected with the rotation center of the nozzle 34. An input pipe 341 is installed at the bottom of the nozzle 34, a hose 342 is installed at the bottom of the input pipe 341, and the bottom of the hose 342 and the adjusting pipe 33 are connected to each other, a clamping shaft 434 is installed on the side wall of the input pipe 341, a clamping seat 432 is rotatably installed on the clamping shaft 434, the clamping seat 432 is installed on the end of the adjusting pipe 33 and is connected to each other, and a torsion spring 433 is installed on the clamping shaft 434, the torsion spring 433 is respectively clamped on the side wall of the clamping seat 432 and the side wall of the input pipe 341, the end of the clamping shaft 434 is connected to the rotation center of the swing arm 43, a strip groove 431 is opened inside the swing arm 43, and the strip groove 431 is slidably connected to the synchronization rod 421. Through the cooperation of the swing arm 43 with the synchronization rod 421, the clamping shaft 434 and other components, the up and down movement of the top rod 42 can be accurately converted into the angle change of the nozzle 34, and the setting of the torsion spring 433 enables the nozzle 34 to automatically reset after swinging, further expanding the irrigation range, reducing the irrigation blind area, making the irrigation more comprehensive and uniform, and providing a more ideal growth environment for vegetables.

[0055] The implementation principle of the vegetable planting irrigation device of the present invention is as follows:

[0056] When irrigation is needed, the operator connects the connecting pipe 11 and the external water supply device to each other. The water can be transported to the spray pipe 1 through the external water supply. Then the water can enter the regulating pipe 33 through the sleeve 32, and finally sprayed outward through the nozzle 34, thereby achieving the purpose of irrigating the vegetable field.

[0057] When water flows in the connecting pipe 11, the water impacts the fan blades 222 at a certain flow rate and impact force. The special shape design of the fan blades 222 enables it to efficiently convert the kinetic energy of the water flow into its own rotational power, thereby driving the synchronous shaft 22 connected thereto to rotate smoothly. This method of using the energy of the water flow itself to drive does not require additional electricity or power equipment, greatly saves energy consumption, reduces irrigation costs, and also reduces the risk of failure caused by additional power equipment, thereby improving the stability and reliability of the device operation.

[0058] The rotation of the synchronous shaft 22 can drive the adjusting roller 2 to rotate. The cam groove 21 on the adjusting roller 2 presents a specific trajectory change as the adjusting roller 2 rotates. The slide bar 211 fits tightly in the cam groove 21 and slides as the trajectory of the cam groove 21 changes, and finally drives the slide bar 211 to slide back and forth horizontally. The positioning frame 334 on the top of the slide bar 211 is rigidly connected to the slide bar 211, and the positioning frame 334 slides back and forth accordingly. The sealing plate 3 connected to the positioning frame 334 slides in the notch 14 on the spray pipe 1 at this time. The sealing plate 3 can fit tightly in the notch 14, effectively preventing the leakage of water flow during the horizontal displacement of the sprinkler 34. The movement of the sealing plate 3 drives the sleeve 32 to slide in the notch 14 on the spray pipe 1, realizing the horizontal position change of the sprinkler 34. This design of realizing the horizontal displacement of the sprinkler 34 by water flow drive enables irrigation to cover a wider area, avoids the occurrence of irrigation dead corners, ensures that every part of the vegetable planting field can be evenly irrigated, and is conducive to the balanced growth of vegetables.

[0059] When the sealing plate 3 slides back and forth, the slide plate 31 on the side wall of the sealing plate 3 also slides in the guide rod 311, providing a stable guiding effect for its movement, so that the moving direction of the sealing plate 3 always remains accurate, avoiding deviation or shaking, thereby ensuring the stability and accuracy of the nozzle 34 during the horizontal displacement process. When the sealing plate 3 slides, the sealing plate 3 can compress the force storage spring 312, so when the sealing plate 3 needs to be reset, the elastic potential energy stored in the force storage spring 312 can be released, so that the sealing plate 3 can quickly and smoothly return to the initial position after the water flow stops driving, and prepare for the next working cycle, thereby extending the service life of the device.

[0060] During the horizontal displacement of the nozzle 34, when the regulating tube 33 moves to the position of the lifting groove 362 along with the sleeve 32, the protrusion 361 on the synchronous bracket 36 of the side wall of the regulating tube 33 begins to slide in the lifting groove 362. The lifting groove 362 is in an inclined state. As the protrusion 361 moves along the inclined direction in the lifting groove 362, the height of the regulating tube 33 and the nozzle 34 gradually rises. At the same time, the blocking block 332 in the regulating tube 33 moves in the conical inner cavity 331 as the height of the regulating tube 33 changes under the drive of the vertical rod 333. Since the diameter of the blocking block 332 is smaller than the diameter of the conical inner cavity 331, when the height of the regulating tube 33 rises, the gap between the conical inner cavity 331 and the blocking block 332 gradually increases, the water flow can pass more smoothly, and the flow rate increases accordingly. On the contrary, when the height decreases, the gap decreases, the water flow is hindered more, and the flow rate decreases, thereby cleverly realizing the control of the water flow rate according to the height. Such a design can automatically adjust the water flow rate according to the different heights of the nozzle 34. When the nozzle 34 is lower, a smaller water flow rate can avoid impact damage to the vegetables; when the nozzle 34 is higher, increasing the water flow rate can ensure the expansion of the irrigation range and ensure the irrigation effect.

[0061] When the adjusting tube 33 slides on the sleeve 32, the limit block 353 on the side wall of the sleeve 32 slides on the limit rod 351. The limit rod 351 limits the moving direction of the limit block 353, thereby ensuring the stability and safety of the device during operation, avoiding damage or malfunction of the device due to excessive movement of components, and facilitating the subsequent resetting operation through the limit spring 354.

[0062] In addition, when the adjusting tube 33 moves to the position of the guide block 4, the top rod 42 at the bottom of the synchronous bracket 36 is slidably connected with the wave groove 41 on the guide block 4. The wave groove 41 has a unique wave-shaped profile. As the adjusting tube 33 moves, the wave groove 41 pushes the top rod 42 to move up and down according to its profile shape, and the synchronous rod 421 at the top of the top rod 42 slides in the strip groove 431 of the swing arm 43. Due to the guiding effect of the strip groove 431, the swing arm 43 is driven to swing around the rotation center of the nozzle 34. The swing arm 43 drives the input pipe 341 and the nozzle 34 to rotate through the clamping shaft 434. Due to the action of the torsion spring 433, the nozzle 34 can automatically reset after swinging. This design of the angle change of the nozzle 34 enables the irrigation water to be sprayed out at different angles, further expanding the irrigation range, reducing the irrigation blind area, making the irrigation more comprehensive and uniform, and providing a more ideal growth environment for vegetables.
