Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment technology, and in particular to an agricultural water-saving irrigation device for agricultural technology promotion. Background Technology

[0002] Agricultural water-saving irrigation is a modern irrigation method that improves water resource utilization efficiency through technological means. It follows the water requirements of crops and employs technologies such as drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and pipeline water delivery to precisely and evenly deliver water to the crop roots or soil surface. Compared to traditional flood irrigation, it effectively reduces deep seepage, surface runoff, and evaporation losses, typically saving 30%-60% of water. Water-saving irrigation is widely used in fields, orchards, and greenhouses, and is a key measure for achieving sustainable agricultural development in arid and semi-arid regions.

[0003] Currently, water-saving irrigation methods are often used in the process of planting trees in agriculture. However, existing irrigation devices are usually quantitative irrigation. As trees grow, the amount of irrigation water required also increases. Traditional quantitative irrigation methods may result in insufficient or excessive irrigation at different growth stages of trees, affecting their normal growth. Summary of the Invention

[0013] As a further aspect of the present invention: the water inlet push rod is hollow to form a water inlet cavity, a shaft is fixedly connected to the inner wall of the water guide tube along the axial direction, the end of the shaft extends into the inner cavity of the water inlet push rod and is connected to a blade, a water inlet pipe is connected to the outer wall of the water inlet push rod, a backing plate is fixedly connected to the end of the water inlet push rod, the backing plate is arc-shaped and rests against the tree trunk, and a spring is provided between the back of the backing plate and the inner wall of the mounting rod.

[0014] As a further aspect of the present invention: an annular groove is provided on the outer wall of the water guide cylinder, and the water inlet ring is adapted to be rotatably installed in the annular groove.

[0019] The beneficial effects of this invention are:

[0020] (1) By setting up a water guiding mechanism and an irrigation mechanism, the water source flows through the water inlet pipe, the water inlet push rod and the water guiding cylinder in sequence. The water guiding cylinder is driven to rotate relative to the water inlet ring by the impact of the water source flowing in the water inlet push rod. When the water guiding cylinder rotates, it will intermittently connect with the water inlet ring, thereby realizing intermittent water intake into the water inlet ring. The water source in the water inlet ring will flow to the irrigation nozzle through the valve control component, thereby ensuring stable water supply for irrigation while effectively reducing water consumption and achieving the purpose of water-saving irrigation.

[0021] (2) During irrigation, as the trunk grows thicker, the water inlet push rod will move radially along with the trunk. The water inlet push rod will push the water guide tube, the water inlet chamber ring, and the adjusting push rod to move synchronously. When the water inlet chamber ring moves radially, it will synchronously drive the valve control component to adjust the irrigation water volume, so that the irrigation water volume can be adaptively adjusted and increased with the growth and development of the trunk to meet the increasing water demand of the tree during cultivation. At the same time, when the adjusting push rod moves radially, it will synchronously drive the nozzle mounting plates at both ends to swing outward through the connecting rod, so that the irrigation spraying area of ​​the irrigation nozzle can be automatically expanded and extended with the expansion of the trunk root system, so that the irrigation area can effectively cover the root system's water absorption range with the trunk as the center. That is, the irrigation water volume and irrigation range can be adaptively adjusted during the trunk growth process, which greatly improves the irrigation effect. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-4 As shown, the present invention is an agricultural water-saving irrigation device for agricultural technology extension, comprising:

[0040] The installation mechanism 1 includes a pair of semi-circular installation rods 11 that surround the tree trunk to form a complete circular installation platform.

[0041] The support mechanism 2 includes a support seat 21 evenly arranged in the circumference. The support seat 21 is fixedly connected to the outer wall of the mounting rod 11. A set of valve control components 22 are symmetrically arranged on the support seat 21. A support frame 23 is fixedly connected to the bottom end of the support seat 21.

[0042] The water guiding mechanism 3 includes a water inlet push rod 31, a water guiding cylinder 32, and an adjusting push rod 34 arranged coaxially in sequence. The water inlet push rod 31 slides radially through the mounting rod 11. One end of the water inlet push rod 31 abuts against the tree trunk, and the other end of the water inlet push rod 31 is sealed and rotated with the water guiding cylinder 32. The water guiding cylinder 32 is rotatably installed in the support base 21. The tail end of the water guiding cylinder 32 is rotatably engaged with the adjusting push rod 34. A water inlet chamber ring 33 is rotatably installed on the outer wall of the water guiding cylinder 32. The water inlet chamber ring 33 slides radially relative to the support base 21.

[0043] The irrigation mechanism 4 includes a set of symmetrically arranged nozzle mounting plates 41. The ends of the nozzle mounting plates 41 are rotatably engaged with the support base 21. The top two ends of the adjusting push rod 34 are rotatably mounted with connecting rods 43. The other ends of the connecting rods 43 are rotatably engaged with the corresponding nozzle mounting plates 41. A plurality of irrigation nozzles 42 are uniformly fixed on the nozzle mounting plates 41.

[0044] The water flow inside the inlet push rod 31 will cause the water guide tube 32 to rotate relative to the inlet chamber ring 33. The water flow inside the water guide tube 32 will intermittently enter the inlet chamber ring 33 during the rotation process. Both ends of the inlet chamber ring 33 are connected to the inlet end of the valve control component 22. The outlet end of the valve control component 22 is connected to the corresponding irrigation nozzle 42. The radial movement of the inlet chamber ring 33 will drive the valve control component 22 to adjust the irrigation water volume. The radial movement of the adjustment push rod 34 will drive the irrigation mechanism 4 to adjust the irrigation range.

[0045] Specifically, by setting up the installation mechanism 1 and the support mechanism 2, a circular installation platform can be formed around the tree trunk, and it is supported and fixed on the ground by the support frame 23, so that the entire installation platform maintains structural stability and provides a stable installation space for the water guiding mechanism 3 and the irrigation mechanism 4. At the same time, the circular structure allows the water guiding mechanism 3 and the irrigation mechanism 4 to be evenly arranged around the tree trunk, which is conducive to the subsequent irrigation spraying area being evenly distributed with the tree trunk as the center.

[0046] More specifically, by setting up a water guiding mechanism 3 and an irrigation mechanism 4, the water source flows sequentially through the water inlet pipe 312, the water inlet push rod 31, and the water guiding cylinder 32. The water guiding cylinder 32 rotates relative to the water inlet chamber ring 33 due to the impact of the water flowing in the water inlet push rod 31. When rotating, the water guiding cylinder 32 intermittently connects with the water inlet chamber ring 33, thereby achieving intermittent water intake into the water inlet chamber ring 33. The water source in the water inlet chamber ring 33 will flow to the irrigation nozzle 42 through the valve control component 22, thereby ensuring stable water supply for irrigation while effectively reducing water consumption and achieving the purpose of water-saving irrigation.

[0047] More specifically, during irrigation, as the tree trunk grows thicker, the water inlet push rod 31 will move radially accordingly. The water inlet push rod 31 will push the water guide tube 32, the water inlet chamber ring 33, and the adjusting push rod 34 to move synchronously. When the water inlet chamber ring 33 moves radially, it will simultaneously drive the valve control component 22 to adjust the irrigation water volume, so that the irrigation water volume can be adaptively adjusted and increased as the tree trunk grows and develops, in order to meet the increasing water demand of the tree during cultivation. At the same time, when the adjusting push rod 34 moves radially, it will simultaneously drive the nozzle mounting plates 41 at both ends to swing outward through the connecting rod 43, so that the irrigation spraying area of ​​the irrigation nozzle 42 can be automatically expanded and extended as the tree trunk root system expands. This allows the irrigation area to effectively cover the area of ​​root infiltration and water absorption with the tree trunk as the center. In other words, it can achieve adaptive adjustment of irrigation water volume and irrigation area during tree trunk growth, greatly improving the irrigation effect.

[0048] like Figure 6 and Figure 7 As shown, the valve control assembly 22 includes a rotating sleeve 221 rotatably mounted on the upper end of the support base 21. A transmission gear 222 is fixedly sleeved on the outer wall of the rotating sleeve 221. A control rod 223 is threaded through the inner wall of the rotating sleeve 221. A valve stem 2231 is fixedly connected to the bottom end of the control rod 223. The valve stem 2231 extends into the valve seat 224 and is fixedly connected to a conical valve core 2232. The valve seat 224 is fixedly mounted in the support base 21. A mating groove 2241 adapted to the valve core 2232 is provided at the bottom of the inner cavity of the valve seat 224.

[0049] Specifically, by setting the valve control component 22, when the water inlet ring 33 moves radially outward on the support seat 21, the water inlet ring 33 will drive the toothed plate 332 to move synchronously. The toothed plate 332 will drive the transmission teeth 222 on both sides to start rotating. The transmission teeth 222 will drive the rotating sleeve 221 to rotate synchronously, thereby causing the control rod 223 inside the rotating sleeve 221 to start to rise axially. The control rod 223 will drive the valve core 2232 to move synchronously upward in the valve seat 224 through the valve rod 2231. At this time, the cross-sectional area of ​​the medium flowing in the valve seat 224 will gradually increase, and the flow rate will also increase accordingly. Thus, the radial movement of the water inlet ring 33 realizes the automatic adjustment of the flow rate. Moreover, the increase in flow rate corresponds to the growth rate of the tree trunk. The faster the tree grows, the more irrigation water is increased, thereby effectively meeting the water demand during the tree growth process.

[0050] like Figure 2 and Figure 3 As shown, the water inlet push rod 31 is hollow inside to form a water inlet cavity. A shaft 321 is fixedly connected to the inner wall of the water guide tube 32 along the axial direction. The end of the shaft 321 extends into the inner cavity of the water inlet push rod 31 and is connected to a paddle 322. A water inlet pipe 312 is connected to the outer wall of the water inlet push rod 31. A backing plate 311 is fixedly connected to the end of the water inlet push rod 31. The backing plate 311 is arc-shaped and rests against the tree trunk. A spring 313 is provided between the back of the backing plate 311 and the inner wall of the mounting rod 11.

[0051] Specifically, in its natural state, the support plate 311 is firmly pressed against the tree trunk surface by the spring 313. Water flows through the inlet pipe 312 into the inlet push rod 31 and then into the guide tube 32. During the flow, the water impacts the blade 322, causing it to rotate. The blade 322, through the shaft 321, drives the guide tube 32 to rotate around its axis, thus effectively utilizing the kinetic energy of the flowing water. The rotation of the guide tube 32 can be achieved without manual intervention or additional power. The guide tube 32 can be made of PVC material, which effectively reduces the overall weight while maintaining sufficient structural strength, allowing the guide tube 32 to rotate smoothly even at lower water flow rates.

[0052] like Figures 4-7 As shown, an annular groove 323 is provided on the outer wall of the water guide cylinder 32, and the water inlet ring 33 is adapted to be rotatably installed in the annular groove 323. Water guide holes 324 are provided through the upper and lower ends of the annular groove 323, and a water inlet hole 333 is provided through the top of the inner wall of the water inlet ring 33. The water guide hole 324 is intermittently connected with the water inlet hole 333 as the water guide cylinder 32 rotates. Sealing rings 325 are provided between the inner walls on both sides of the annular groove 323 and the water inlet ring 33.

[0053] Furthermore, a connecting block 331 is fixedly connected to the top of the water inlet ring 33, and a limiting groove 211 is provided radially through the upper end of the support base 21. The connecting block 331 is adapted to slide and install in the limiting groove 211. A toothed plate 332 is fixedly provided at the top of the connecting block 331. Both sides of the toothed plate 332 are engaged with the transmission teeth 222. The two ends of the water inlet ring 33 are connected to the water inlet end of the valve seat 224 through the first hose 334.

[0054] Specifically, due to the limiting sliding fit between the connecting block 331 and the limiting groove 211, the water inlet ring 33 is subject to rotational constraint. At the same time, due to the ring groove 323, under the pushing action of the water guide tube 32, the water inlet ring 33 can only move radially along the limiting groove 211, and will not affect the free rotation process of the water guide tube 32 relative to the water inlet ring 33.

[0055] More specifically, during the continuous rotation of the water guide tube 32, the water guide hole 324 will intermittently connect with the water inlet hole 333. When connected, the water flow in the water guide tube 32 will smoothly enter the water inlet ring 33. When the water guide hole 324 and the water inlet hole 333 intersect, the water guide hole 324 will be blocked and sealed by the inner wall of the water inlet ring 33, thus stopping the water intake. This intermittent water intake process to the water inlet ring 33 is achieved by utilizing the rotation of the water guide tube 32. During the rotation, the water guide tube 32 maintains a continuous and good sealing performance with the water inlet ring 33 through the sealing ring 325, avoiding water leakage and waste of water resources.

[0056] like Figure 7 and Figure 8 As shown, a water distribution pipe 44 is fixedly installed on one side of the nozzle mounting plate 41. Each irrigation nozzle 42 is connected to the water distribution pipe 44 through a branch pipe 421. The end of the water distribution pipe 44 is connected to the water outlet of the valve seat 224 through a second flexible hose 441.

[0057] Specifically, after passing through the valve control assembly 22, the water flows through the second hose 441 into the water distribution pipe 44, and then supplies water to each irrigation nozzle 42 through each branch pipe 421, so that each irrigation nozzle 42 can spray water evenly and stably. At the same time, because the second hose 441 is flexible, it can extend and retract accordingly when the nozzle mounting plate 41 swings outward, thereby ensuring the normal delivery and flow of water source.

[0058] like Figure 4 As shown, the adjusting push rod 34 extends out from the support base 21, and a bracket 212 is provided at the tail end of the support base 21. The adjusting push rod 34 is slidably installed in the bracket 212.

[0059] Specifically, since the adjusting push rod 34 has a certain length, in order to ensure the stability of the adjusting push rod 34 when moving axially, a bracket 212 is set to provide support and limit the adjusting push rod 34. This not only provides a support point for the long rod structure to avoid swaying under the action of gravity, but also provides a guiding function for the adjusting push rod 34 so that it always moves in the correct direction.

[0060] like Figure 9 and Figure 10 As shown, one end of the mounting rod 11 is rotatably mounted on the end seat 12, and the other end of the mounting rod 11 is closed with each other and locked and fixed by the connector 14. The mounting rod 11 is provided with a positioning sleeve 111 through which the water inlet push rod 31 slides. The mounting rod 11 is provided with a water passage cavity 112, and the water inlet pipe 312 is connected to the water passage cavity 112. The upper end of the mounting rod 11 is connected to a water passage pipe 13, which is used to introduce external water into the water passage cavity 112.

[0061] Specifically, after the mounting rod 11 is closed into a circle, it is locked in place by the connector 14 to ensure structural stability. The connector 14 can be a bolt, a locking pin, etc., depending on the actual needs, as long as it allows for quick assembly and disassembly by the staff. The positioning sleeve 111 provides support and guidance for the water inlet push rod 31, enabling the water inlet push rod 31 to move stably in the radial direction. The water pipe 13 is connected to an external water source, which can continuously supply water to the water passage chamber 112. The water flow in the water passage chamber 112 will flow continuously and stably through the water inlet pipe 312 to the water guiding mechanism 3.

[0062] The working principle of this invention is as follows: Figures 1-10 As shown, in use, the installation rod 11 is first arranged around the tree trunk to form a circular structure and locked and fixed by the connector 14. The bottom of the installation rod 11 is supported and fixed on the ground by the support frame 23, thus forming a stable installation platform. During irrigation, the support plate 311 is pressed tightly against the tree trunk surface by the spring 313. The water pipe 13 is connected to an external water source, which can continuously supply water to the water passage chamber 112. The water flow in the water passage chamber 112 will be introduced into the water inlet push rod 31 through the water inlet pipe 312 and flow into the water guide tube 32. During the flow, the water flow will impact the blade 322 and drive it to rotate. The blade 322 will drive the water guide tube 32 to rotate around the axis through the shaft 321. When the water guide tube 32 rotates, it will intermittently connect with the water inlet chamber ring 33, thereby realizing intermittent water intake into the water inlet chamber ring 33. The water source in the water inlet chamber ring 33 will flow to the irrigation nozzle 42 through the valve control component 22, thereby ensuring stable water supply for irrigation while effectively reducing water consumption and achieving the purpose of water-saving irrigation.

[0063] As the tree trunk grows thicker, the inlet push rod 31 will move radially accordingly, pushing the water guide cylinder 32, the inlet chamber ring 33, and the adjusting push rod 34 to move synchronously. During the radial displacement of the inlet chamber ring 33, it will drive the toothed plate 332 to move synchronously. The toothed plate 332 will then drive the transmission teeth 222 on both sides to rotate, which in turn drives the rotating sleeve 221 to rotate synchronously. This causes the control rod 223 inside the rotating sleeve 221 to begin axially lifting. The control rod 223 will then drive the valve core 2232 to move synchronously upward within the valve seat 224 via the valve stem 2231. At this time, the cross-sectional area of ​​the medium flowing within the valve seat 224 will gradually increase, and the flow rate will increase accordingly. Thus, the radial movement of the inlet chamber ring 33 achieves automatic regulation of the water flow, and the increase in flow rate corresponds to the growth rate of the tree trunk. The faster the tree grows, the more irrigation water is needed, effectively meeting the water demand during the tree's growth process. At the same time, when the adjusting push rod 34 moves radially, it will drive the nozzle mounting plates 41 at both ends to swing outward through the connecting rod 43, so that the irrigation spraying area of ​​the irrigation nozzle 42 can be automatically expanded and extended as the tree trunk and root system expand, so that the irrigation area can effectively cover the range of root penetration and water absorption with the tree trunk as the center.

[0064] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
