Description

Technical Field

[0001] This invention relates to the field of water resource management technology, specifically to an agricultural water-saving irrigation system for water resource management. Background Technology

[0002] In agricultural production, in order to irrigate agricultural areas, different methods such as surface irrigation, ordinary sprinkler irrigation, and even micro-irrigation are often adopted according to different agricultural environments or crop needs. Drip irrigation is one of the most water-saving irrigation methods. In some water-scarce areas, in order to ensure good water-saving effects, drip irrigation pipes are often laid in the cultivated area for drip irrigation.

[0003] However, the positions of the drip inlets or sprinklers in existing drip irrigation pipes are fixed. Some drip irrigation pipes, designed for large-area crop irrigation, often have multiple fixed drip inlets. When subsequent targeted or spot-based drip irrigation is needed, using multiple inlets again easily leads to water waste. To avoid waste, workers must close the extra inlets, increasing labor intensity. Furthermore, in water-scarce areas, dry weather can easily damage some crops, such as those whose economic value lies in their stems and leaves. Simple drip irrigation often only replenishes water to the roots, failing to provide effective targeted irrigation when the stems and leaves are exposed to high temperatures. Workers then need to run a separate pipeline for sprinkler irrigation, which is inconvenient in practice. Summary of the Invention

The rear through hole of the temporary storage block is equipped with an injection pipe, which is connected to the water inlet pipe. The end cap is installed on the top of the temporary storage block.

[0010] Preferably, the spray frame is composed of several carriage components connected end to end, and the carriage components are arranged in two sets in parallel front to back, with guide rails installed on the inner sidewalls between the opposite surfaces of the carriage components.

[0011] A sprocket shaft is installed on the inner side of the end of the spray frame away from the assembly frame. A gearbox is installed on the surface of the assembly frame above the servo motor. The input end of the gearbox meshes with the gear teeth on the surface of the rotating shaft. The output end of the gearbox is connected to the sprocket shaft through a transmission chain and a sprocket. The end of the spray bar is connected to the transmission chain through a guide rail and a slider.

[0012] Preferably, a stirrer is installed at the top of the dosing tank, and a dosing hopper is installed at the top of the dosing tank on one side of the stirrer.

[0013] Preferably, a T-joint is installed between the one-way pipe connector and the drip irrigation device. The connection between the T-joint and the drip irrigation device is L-shaped, and a threaded part is provided at the top of the bend of the L-shaped structure of the T-joint.

[0016] Preferably, a connector is installed at one end of the tee tube that is away from the drip irrigation device, and a screw fitting is movably sleeved on the surface of the connector.

[0017] Preferably, an adjusting pipe is installed between two adjacent branch pipes, and a mating plate is installed at the end of both the branch pipe and the adjusting pipe. A connector is fitted onto the outer side of the two mating plates, and a groove is provided between the connector and the mating plate, with a locking seal installed inside the groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This water resource management agricultural water-saving irrigation system, designed for agricultural irrigation conditions, allows for large-area, multi-point drip irrigation by drawing water locally and filtering the water. It also provides auxiliary irrigation for applications such as pesticides or fertilizers. Utilizing prefabricated sliding frames and branch pipes, the size of the drip irrigation pipes can be adjusted to accommodate irrigation areas of varying lengths. This flexible installation provides stable support for the overhead sprinkler system, enabling spraying of crops requiring foliar spraying. This system combines drip irrigation and sprinkler irrigation. Furthermore, targeted treatment of diseased plants can be achieved directly using the drip irrigation system, resulting in diversified water resource management while meeting various agricultural irrigation needs.

[0020] 2. This water-saving agricultural irrigation system for water resource management uses multiple branch pipes to form drip irrigation pipes. This allows for adjustment of the actual size of the drip irrigation pipes, and multiple one-way connectors are installed on them. This allows for targeted installation of drip irrigation devices in multiple locations during drip irrigation, facilitating placement near nearby crops, enhancing the drip irrigation effect, and preventing water waste. The connectors can also open the flexible one-way valves to facilitate water drainage and automatic plugging of the one-way connectors using the one-way valves.

[0021] 3. This water-saving agricultural irrigation system for water resource management uses an L-shaped connection between the T-joint and the drip irrigation device. This facilitates the T-joint effect while allowing for top-down installation with the help of a fixed-feeder. When targeted crop application is required, the system delivers the pesticide to the drip irrigation device. With the cooperation of the side-sealing pipe and the guide cavity, the side-sealing pipe can seal the guide cavity, enabling the fixed-feeder to deliver the pesticide solution to the drip irrigation device independently. By controlling the depth of the thread rotation, i.e., the relative vertical position of the threaded part and the sealing sleeve, the guide cavity can be opened or closed, meeting the needs for flexible manual control.

[0022] 4. This water-saving agricultural irrigation system for water resource management can temporarily store and even transport incoming water through a temporary storage block. With the support of bearing components and a mechanical seal, water continues to enter even as the shaft rotates. Driven by a servo motor, it achieves multiple functions, rotating the shaft to wind up the hose. Gear meshing drives the transmission chain, which in turn moves the spray bar left and right while simultaneously winding up the hose. This prevents excessively long hoses from contacting crops below and facilitates control of irrigation operations in different areas. Attached Figure Description

[0032] 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.

They are used only for the convenience of describing this invention and for 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. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] like Figures 1 to 8As shown, this embodiment of the agricultural water-saving irrigation system for water resource management includes a sand filter tank 2 and a water pump 1. The sand filter tank 2 is an existing tank filled with quartz filter material and equipped with a backwashing component. The output end of the water pump 1 is connected to the input end of the sand filter tank 2 through a pipe. Since agricultural irrigation environments are mostly in the field, water can be drawn locally. After the water pump 1 draws water into the sand filter tank 2, it can undergo sand filtration to prevent harmful substances in the water from affecting crop growth during subsequent irrigation. A chemical dosing tank 4 is installed at the output end of the sand filter tank 2 through a pipe. The chemical dosing tank 4 is connected to the output end of the sand filter tank 2 through a pipe and the pump body, which can further treat the water. The system provides centralized guidance and creates a temporary storage effect. A stirrer 3 is installed at the top of the dosing tank 4. The stirrer 3 is a combination of a motor, stirring rod, and other components. The stirring rod is located inside the dosing tank 4, and a dosing hopper is installed at the top of the dosing tank 4 on one side of the stirrer 3. When fertilizing crops, liquid fertilizer can be directly placed into the dosing tank 4 through the dosing hopper to mix with the water, facilitating subsequent fertilization. The output end of the dosing tank 4 is connected to an inlet pipe 23 and a drip irrigation pipe 13 via a flow combination valve 14. The flow combination valve 14 itself is a three-way flow valve, which can meter the delivered water, facilitating water resource management. The inlet pipe 23 is a flexible hose, and the drip irrigation pipe 13 is installed in a serpentine pattern, suitable for drip irrigation of large areas of crops. It passes around the crops, especially around small fruit trees, allowing for specialized directional drip irrigation. Several fixing kits 12 are detachably installed on the surface of the drip irrigation pipe 13. The fixing kit 12 is similar to a half-sleeve and is fixed to the surface of the drip irrigation pipe 13 by bolts. The bottom end of the fixing kit 12 is equipped with a ground nail, which is directly inserted into the soil to limit and fix the fixing kit 12 and even the area of ​​the drip irrigation pipe 13. The top of the fixing kit 12 is equipped with a telescopic support rod 9, which is actually a spiral tube with studs installed vertically through threads, and the studs extend upwards. By rotating the stud, it can move up and down along the thread or even the spiral tube to achieve telescopic adjustment control. The top of the telescopic support rod 9 is equipped with a spray frame 8. In actual use, the size of the drip irrigation pipe 13 used is different according to the needs of different irrigation areas. Therefore, there are several fixed parts 12 and even telescopic support rods 9, which can form a multi-point support effect for the spray frame 8. The spray frame 8 itself is located above the entire irrigation area. Especially in the process of irrigating rectangular land, it is necessary to spray irrigation on the top of some specific crops. For example, to avoid the top of seedlings from withering due to sun exposure, the top of the seedlings can be sprayed downwards with the help of the spray frame 8.

[0035] The spray frame 8 has an I-shaped structure, arranged parallel front to back, and horizontally along the rectangular crop area. A spraying rod 17 is movably mounted on the inner side of the spray frame 8, allowing it to move left and right by external force. The spraying rod 17 is hollow inside, with several nozzles at its bottom. Two assembly frames 6 are arranged parallel front to back on one side of the spray frame 8, with a large gap between them. A shaft tube 21 is movably mounted between the two assembly frames 6. The shaft tube 21 is hollow inside, and a drive mechanism is mounted at one end of it. The drive mechanism can rotate the shaft tube 21. The other end of 1 is equipped with an injection mechanism, into which the water required for irrigation is directly placed, which facilitates subsequent spraying operations. The injection mechanism is connected to the water inlet pipe 23. A coiled tube 18 is installed in the middle of the shaft tube 21, and the coiled tube 18 is connected to the spray rod 17. It should be noted that the coiled tube 18 itself is a flexible hose with high hardness that will not deform under pressure. It is fixedly connected to the shaft tube 21. When the shaft tube 21 rotates, the coiled tube 18 can be wound up, which can drive the spray rod 17 to move left and right, thereby performing mobile spraying irrigation operations.

[0036] The drip irrigation pipe 13 consists of several branch pipes 25. The actual structure of the branch pipes 25 can be set according to the actual irrigation needs, such as setting the branch pipes 25 into an L-shaped or Z-shaped structure. Each branch pipe 25 has several one-way pipe joints 11 installed on its surface. The outer surface of the one-way pipe joint 11 is provided with external threads, and the inside is provided with a one-way valve structure. Foreign objects can enter into it to open the one-way valve, thereby opening the one-way pipe joint 11. The surface of the one-way pipe joint 11 is detachably installed with a drip irrigation device 26. The two are connected by a threaded detachable connection. The bottom of the drip irrigation device 26 can be inserted into the soil to directly drip irrigate the roots of crops in the soil, achieving a water-saving effect.

[0037] Specifically, the drive mechanism includes a servo motor 15 and a rotating shaft 19. The servo motor 15 is mounted on the surface of any of the mounting brackets 6 and is itself a motor equipped with a forward and reverse rotation control circuit. The rotating shaft 19 is mounted on the output end of the servo motor 15 and passes through the mounting bracket 6 and extends to one end of the shaft tube 21. The rotating shaft 19 itself is driven by the servo motor 15 to rotate, and the rotating shaft 19 itself is connected to the shaft tube 21, thereby driving the shaft tube 21 to rotate and achieve a rotating winding effect.

[0038] Furthermore, the injection mechanism includes an injection pipe 5, a temporary storage block 20, a bearing component 22, and an end cap 24. The temporary storage block 20 is mounted on the top of another assembly frame 6, positioned away from the servo motor 15. The temporary storage block 20 has through holes at its front and rear, and an internal cavity that facilitates water flow. The front through hole of the temporary storage block 20 is connected to the other end of the shaft tube 21 via the bearing component 22, thus creating an internal cavity connection. The injection pipe 5 is installed in the rear through hole of the temporary storage block 20, with its opening facing outwards. The injection pipe 5 is connected to the water inlet pipe 23. Next, it should be noted that the injection pipe 5 is fixedly connected to the water inlet pipe 23. The water transported by the water inlet pipe 23 directly enters the injection pipe 5 and then enters the shaft tube 21 after passing through the temporary storage block 20 and the bearing component 22. It should be noted that because the bearing component 22 adopts the form of mechanical seal, the rotation of the shaft tube 21 itself will not affect the water transported inside, and the water can be transported normally. The end cap 24 is installed on the top of the temporary storage block 20. The end cap 24 can be opened to clean impurities inside the temporary storage block 20.

[0039] Furthermore, the spray frame 8 is composed of several carriage components 7 connected end to end, and the carriage components 7 are arranged in two sets in parallel front to back. The carriage components 7 themselves are similar to channel steel structures, and can be detachably connected by bolts or the like during the end-to-end connection process. Thus, different numbers of carriage components 7 can be used to form spray frames 8 of different sizes to meet irrigation needs of different area sizes. The inner sidewalls between the opposite faces of the carriage components 7 are all equipped with guide rails 16, that is, the carriage component 7 itself is in the form of a trough, and its inner groove is provided with guide rails 16 for guiding and limiting movement. Thus, when the spray rod 17 moves left and right under force, the guide rails 16 can limit and guide the movement of the spray rod 17. It should be noted that because there are several carriage components 7, each carriage component 7 The guide rail 16 is connected left and right for convenient use. A sprocket shaft 38 is installed on the inner side of the end of the spray frame 8, away from the assembly frame 6. The sprocket shaft 38 has a sprocket structure on its inner side. A gearbox 39 is installed on the surface of the assembly frame 6 above the servo motor 15. The gearbox 39 contains a gear set. The input end of the gearbox 39 meshes with the gear teeth on the surface of the rotating shaft 19. When the rotating shaft 19 rotates, the gears drive the input shaft of the gearbox 39 to rotate, and the gears perform speed changes. The output end of the gearbox 39 is connected to the sprocket shaft 38 via a transmission chain 40 and a sprocket, thus transmitting the motion output from the gearbox 39 via the transmission chain 40. The end of the spray bar 17 is connected to the transmission via the guide rail 16 and a slider. The spray bar 17 is connected by the chain 40, thus moving synchronously with the transmission chain 40. This provides the spray bar 17 with power away from the servo motor 15, thereby changing the position of the spraying operation. It is important to note that the slider of the spray bar 17 is fixedly connected to the transmission chain 40, and the slider itself forms a limiting fit with the guide rail 16. The spray bar 17 is a two-end structure. To facilitate the stable movement of the spray bar 17, in addition to a single sprocket shaft 38 on the inner side of the spray frame 8 near the servo motor 15, two additional sprocket shafts 38 arranged horizontally on the inner side of the spray frame 8 away from the servo motor 15 should be installed, based on the I-shaped structure of the carriage 7. The sprockets on these two sprocket shafts 38 are connected by the transmission chain 40, and the servo motor 15 drives the spray bar 17. When a single drive chain 40 moves, due to the limiting effect of the slider and the guide rail 16, the other drive chain 40 will also move synchronously, thereby causing the spraying rod 17 to move horizontally in the left and right directions. Therefore, the transmission ratio of the gearbox 39 needs to be set. When the servo motor 15 rotates forward, the drive chain 40 drives the spraying rod 17 to move away from the servo motor 15. The shaft tube 21 releases the wound coiled tube 18 to ensure that the coiled tube 18 will not be pulled when the spraying rod 17 moves. When the servo motor 15 rotates in reverse, the drive chain 40 drives the spraying rod 17 to move closer to the servo motor 15. At this time, the shaft tube 21 winds up the coiled tube 18 to prevent the coiled tube 18 from being too long and touching the crops below, thus preventing damage to the crops.

[0040] Furthermore, a three-way connector 30 is installed between the one-way connector 11 and the drip irrigation device 26. The three-way connector 30 has three ports. The connection between the three-way connector 30 and the drip irrigation device 26 is L-shaped. A threaded part 32 is provided at the top of the bend of the L-shape. The threaded part 32 is actually a threaded opening facing the direction of the three-way connector 30. A sealing sleeve 33 is connected to the internal thread of the threaded part 32. The sealing sleeve 33 and the threaded part 32 are connected in a detachable manner through the thread. A dispenser 29 is installed on the inner side of the sealing sleeve 33. The dispenser 29 is similar to a small water tank. An end cap is provided on the top. It can be filled with some specific medicines. The sealing sleeve 33 is actually the outer part of the bottom of the dispenser 29.

[0041] Furthermore, a side-sealing tube head 31 is installed at the bottom of the feeder 29. An opening is provided on one side of the side-sealing tube head 31, and the side-sealing tube head 31 extends downward through the sealing sleeve 33. In fact, the entire side-sealing tube head 31 can be used as a liquid outlet component of the feeder 29. The entire sealing sleeve 33 is fixedly sleeved on the top of the side-sealing tube head 31. When the sealing sleeve 33 is rotated along the internal thread of the threaded part 32, the side-sealing tube head 31 moves downward, while the opening on one side is in the upper position, and there is no opening at the bottom. Thus, in the process of diagnosing or treating seedlings, the feeder 29 can be used to hold the liquid medicine, and the liquid medicine flows through the side opening to the drip irrigation device 26 for outlet, realizing the drip irrigation treatment operation for seedlings.

[0042] Furthermore, the tee head 30 below the screw fitting 32 is provided with a guide cavity 34. The guide cavity 34 is narrow at the top and wide at the bottom, and is actually connected to the inlet of the tee head 30. The top of the guide cavity 34 is used in conjunction with the bottom of the side sealing head 31. Under normal circumstances, when the side sealing head 31 is installed downward, the non-open bottom of the side sealing head 31 directly enters through the top opening of the guide cavity 34. The non-open bottom part of the side sealing head 31 can be made of rubber material with moderate hardness, which can deform under force. After contacting the top opening of the guide cavity 34, it can be pressed tightly or even deformed, forming a sealing effect on the guide cavity 34. At this time, the liquid flowing through the drip irrigation device 26 can only be the medicine liquid flowing out from the side opening.

[0043] Furthermore, a connector 27 is installed at one end of the tee head 30 away from the drip irrigation device 26. The end of the connector 27 is beveled. During normal use, it can be directly inserted into the one-way connector 11, thereby opening the one-way valve plate and creating a flow effect for the drip irrigation pipe 13 at that point. A screw assembly 28 is movably sleeved on the surface of the connector 27. The screw assembly 28 itself can be rotated under force and has an internal thread. When the connector 27 is inserted into the one-way connector 11, the screw assembly 28 is directly connected to the surface of the one-way connector 11 by means of the thread, forming a fixed connection effect. A sealing structure such as a sealing ring is configured inside it to form a sealed installation of the connector 27. Water can directly enter the interior of the tee head 30 through the connector 27.

[0044] Furthermore, an adjusting pipe 35 is installed between two adjacent branch pipes 25. Since the entire drip irrigation pipe 13 is a prefabricated pipe, it requires on-site assembly. In cases where the actual serpentine distribution of the drip irrigation pipe 13 covers a wide area, the prefabricated branch pipes 25 may be too small. Shorter adjusting pipes 35 can be used for assembly and connection. Both the ends of the branch pipes 25 and the adjusting pipes 35 are equipped with mating discs 36, similar to flanges. The two mating discs 36 must be used in a mating manner. Connectors 10 are mounted on the outer sides of the two mating discs 36. The connectors 10 are actually two Ω-shaped structural components, connected by a hinge. The connector 10 is connected and fixed with bolts. A groove is provided between the connector 10 and the mating plate 36. When the connector 10 itself is a two-semi-circular structure, after the connector 10 is fixedly installed, the groove forms a circular structure and limits the two mating plates 36 for alignment. This creates a limiting connection between the mating plates 36 and even the adjusting pipe 35 and the branch pipe 25, or between the branch pipes 25 and the branch pipes 25. The groove is equipped with a locking seal 37, which, while squeezing the mating plates 36, creates a sealing effect in the groove gap. Then, the connector 10 is tightened with bolts and nuts to achieve a quick installation of the mating plates 36.

[0045] It should be noted that because the branch pipe 25 is a prefabricated pipe, it is only suitable for rectangular cultivated areas of a certain width. When irrigating a large cultivated area, the cultivated area can be divided into multiple smaller rectangular cultivated areas to facilitate regional irrigation or planting operations. When drip irrigation is required over a larger area, multiple drip irrigation units 26 or even T-joints 30 need to be installed on multiple one-way pipe joints 11. The bottom of the drip irrigation unit 26 is inserted into the soil, and then the valve on it is opened to directly drip irrigate the soil around the crop roots. When performing targeted irrigation, such as drip irrigation for seedlings, the spacing between seedlings should be considered. If the distance is large, the adjusting pipe 35 can be used to increase the gap between two adjacent branch pipes 25, and the seedlings can be planted between the branch pipes 25. If a seedling needs special care due to lack of nutrition or disease, the nutrient solution or medicine can be filled into the dispenser 29. Select a three-way pipe head 30 near the root system of the seedling, open the nut on the screw fitting 32, and install the dispenser 29 on the three-way pipe head 30. When the guide cavity 34 is blocked by the bottom of the side sealing pipe head 31, the medicine flows out from the side opening of the side sealing pipe head 31 and is dripped into the drip irrigation device 26 for specialized drip irrigation.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
