Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and in particular to a water and fertilizer irrigation device for berry cultivation with adjustable spraying range. Background Technology

[0002] In modern agriculture, precision irrigation technology plays a crucial role in improving crop yield and quality. This is especially true in berry cultivation, where berries have high water and nutrient requirements and relatively fragile root systems; proper irrigation methods can significantly improve their growth and yield. Therefore, water and fertilizer irrigation systems for berries with adjustable spray ranges play a vital role in agricultural production. However, existing water and fertilizer irrigation systems for berries have many shortcomings in practical applications, particularly in that the spray nozzles cannot freely adjust the water coverage area. These problems seriously affect irrigation efficiency and crop growth quality.

[0003] Existing irrigation systems for berry cultivation have significant shortcomings in terms of sprinkler head adjustment. The spray range of a sprinkler head determines the uniformity of water and fertilizer distribution, which is particularly important for the growth of berries. However, existing sprinklers often only provide a fixed spray range and cannot be freely adjusted according to actual conditions. For example, the water and nutrient requirements of berries vary at different growth stages, and a fixed spray range cannot meet these changing needs. During the seedling stage, the plant's root system is small and requires concentrated water supply; while during the growing season, the root system expands, requiring a wider distribution of water and fertilizer. Existing sprinklers, lacking adjustment capabilities, cannot adapt to these changes, resulting in uneven water and fertilizer supply and affecting plant growth and development.

[0004] Existing irrigation systems for berry cultivation have limitations in addressing diverse plots and terrain conditions. Berry cultivation typically takes place on various plots with varying soil textures, slopes, and vegetation cover, each with different irrigation requirements. However, existing sprinklers cannot be adjusted to suit specific plot conditions, resulting in significant variations in irrigation effectiveness. For example, on slopes, a fixed spray pattern may cause water to flow along the slope, failing to evenly cover the entire plot; on flat land, a fixed spray pattern may be too concentrated, leading to some areas being overly wet while others are too dry. This inability to freely adjust the spray pattern makes it difficult to achieve optimal irrigation results, impacting crop yield and quality.

[0005] Existing irrigation systems for berry cultivation are inadequate in adapting to varying weather conditions. Weather conditions such as wind speed, humidity, and temperature significantly impact irrigation effectiveness. For example, in strong winds, a fixed spraying area may cause water and fertilizer to be blown away, failing to reach the target area accurately; in hot weather, a fixed spraying area may lead to excessive evaporation, failing to effectively moisten the soil. Existing sprinklers lack adjustment capabilities and cannot dynamically adjust according to weather conditions, resulting in significantly reduced irrigation efficiency. This not only wastes water resources but may also adversely affect plant growth.

[0006] Existing irrigation systems for berry cultivation also lag significantly in automation. In large-scale cultivation, manually adjusting the spray range of the sprinklers is not only inefficient but also prone to human error. While existing irrigation systems have achieved partial automation, there is still considerable room for improvement in adjustment accuracy and stability. For example, some devices exhibit delays and errors when automatically adjusting the spray range, resulting in unsatisfactory irrigation effects. Furthermore, the low level of automation increases the workload of operators, which is detrimental to the long-term development of enterprises. In modern agricultural production, efficient and high-quality irrigation is crucial for ensuring crop growth, and existing irrigation systems clearly fall short in this regard.

[0007] Therefore, how to provide a water and fertilizer irrigation device for berry cultivation with adjustable spraying range is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] One objective of this invention is to provide an adjustable spraying range water and fertilizer irrigation device for berry cultivation. This invention adjusts the distance between the adjusting plate and the top of the spray pipe by rotating an electric motor. The adjusting plate is curved, ensuring more even water spraying. As the adjusting plate gradually approaches the top of the spray pipe, the pressure at the top water inlet gradually increases, allowing the water sprayed along the adjusting plate to travel further. Conversely, as the adjusting plate moves away from the top of the spray pipe, the pressure at the top water inlet gradually decreases, allowing the water sprayed along the adjusting plate to travel closer. This dynamic spraying of water from the top of the spray pipe, covering both the area from far to near and from near to far, irrigates the berry cultivation area.

[0009] This invention establishes a real-time signal connection between a second signal receiver and a first signal receiver, thereby enabling the controller to dynamically spray water from the nozzles from far to near and from near to far, irrigating berry plantations. When automatically adjusting the spray range, it avoids delays and errors that could lead to unsatisfactory irrigation results.

[0010] According to an embodiment of the present invention, a water and fertilizer irrigation device for berry cultivation with adjustable spraying range includes an irrigation tank, a mixing assembly, a controller, a conveying assembly, and a nozzle. The mixing assembly is fixedly installed inside the irrigation tank, the controller is fixedly installed on the outer wall of the irrigation tank, the conveying assembly is fixedly installed on the irrigation tank, and the bottom of the nozzle is fixedly installed on the conveying assembly. The nozzle includes a water spray pipe, a power component, and an adjustment component. The bottom of the water spray pipe is fixedly installed on the end of the delivery component, the power component is rotatably installed inside the water spray pipe, and the adjustment component is slidably installed on the top of the water spray pipe.

[0011] Furthermore, a first water inlet pipe is provided on the top of the irrigation tank, and a second water inlet pipe is provided on the top of the irrigation tank.

[0012] Furthermore, the mixing assembly includes a mixing motor, a mixing rod, and mixing blades, wherein the base of the mixing motor is fixedly installed on the top of the irrigation tank, the rotation of the mixing rod is mounted on the rotating shaft of the mixing motor, and the mixing blades are fixedly installed on the mixing rod.

[0013] Furthermore, a first signal receiver is fixedly mounted on the top of the controller.

[0014] Furthermore, the conveying assembly includes a water pump, a pumping pipe, a main outlet pipe, a cross-laying pipe, and a distribution pipe. The bottom pump base of the water pump is fixedly installed on the outer surface of the irrigation tank. One end of the pumping pipe is fixedly installed on the water pump, and the other end of the pumping pipe extends to the inner bottom of the irrigation tank. One end of the main outlet pipe is fixedly installed on the water pump. The cross-laying pipe is fixedly installed on the other end of the main outlet pipe. The distribution pipe is fixedly installed on the cross-laying pipe, and the top of the distribution pipe is fixedly installed on the bottom of the spray pipe.

[0015] Furthermore, the conveying assembly also includes a first electric valve and a second electric valve, the first electric valve being fixedly installed on the main outlet pipe and the second electric valve being fixedly installed on the branch pipe.

[0016] Furthermore, the water spray pipe has a tapered channel inside and a widening channel inside, a water spray core is fixedly installed at the top inside the water spray pipe, and a flow-encircling plate is fixedly installed inside the widening channel.

[0017] Furthermore, the power assembly includes a power bracket, a power shaft, and an impeller. The power bracket is fixedly installed on the inner wall of the water spray pipe, one end of the power shaft is rotatably installed inside the power bracket, the impeller is fixedly installed on the power shaft, and the other end of the power shaft extends out of the water spray pipe.

[0018] Furthermore, the adjustment assembly includes a guide rod, an adjustment box, a generator, and a battery. The bottom of the guide rod is fixedly installed on the top of the water spray pipe, the bottom of the adjustment box is fixedly installed on the top of the guide rod, the generator is fixedly installed inside the adjustment box, and the rotating shaft of the generator is fixedly installed on the end of the power shaft away from the power support.

[0019] Furthermore, the adjustment assembly also includes a second signal receiver, a motor, a gear pair, a threaded rod, and an adjustment plate. The second signal receiver is fixedly installed on the inner top of the adjustment box, the motor is fixedly installed on the inner top of the adjustment box, the input gear of the gear pair is fixedly installed on the rotating shaft of the motor, the top of the threaded rod is fixedly installed on the output gear of the gear pair, the bottom of the threaded rod is rotatably installed on the top of the water spray pipe, the adjustment plate is slidably installed on the guide rod, and the adjustment plate is threadedly installed on the threaded rod.

[0020] The beneficial effects of this invention are: This invention adjusts the distance between the adjusting plate and the top of the spray pipe by means of an adjustable plate driven by the rotation of an electric motor. The adjusting plate is curved, resulting in more uniform water spraying. As the adjusting plate gradually moves closer to the top of the spray pipe, pressing against the top nozzle, the pressure at the top nozzle gradually increases, and the water sprayed along the adjusting plate travels farther. As the adjusting plate gradually moves away from the top of the spray pipe, the pressure at the top nozzle gradually decreases, and the water sprayed along the adjusting plate travels closer. This allows for dynamic spraying of water from the top of the spray pipe, covering an area from far to near and from near to far, for irrigating berry fields.

[0021] This invention establishes a real-time signal connection between a second signal receiver and a first signal receiver, thereby enabling the controller to dynamically spray water from the nozzles from far to near and from near to far, irrigating berry plantations. When automatically adjusting the spray range, it avoids delays and errors that could lead to unsatisfactory irrigation results. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] Existing irrigation systems for berry cultivation have significant shortcomings in terms of sprinkler head adjustment. The spray range of a sprinkler head determines the uniformity of water and fertilizer distribution, which is particularly important for the growth of berries. However, existing sprinklers often only provide a fixed spray range and cannot be freely adjusted according to actual conditions. For example, the water and nutrient requirements of berries vary at different growth stages, and a fixed spray range cannot meet these changing needs. In the seedling stage, the plant's root system is small and requires concentrated water supply; while in the growth period, the plant's root system expands and requires a wider distribution of water and fertilizer. Existing sprinklers, lacking adjustment capabilities, cannot adapt to these changes, resulting in uneven water and fertilizer supply and affecting plant growth and development.

[0027] Existing irrigation systems for berry cultivation have limitations in addressing different plots and terrain conditions. Berry cultivation typically takes place on various plots with varying soil textures, slopes, and vegetation cover, each with different irrigation requirements. However, existing sprinklers cannot be adjusted to suit the specific conditions of each plot, resulting in significant variations in irrigation effectiveness. For example, on slopes, a fixed spraying area may cause water to flow along the slope, failing to evenly cover the entire plot. On flat land, a fixed spraying area may be too concentrated, leading to some areas being overly wet while others are too dry. This inability to freely adjust the spraying area makes it difficult to achieve optimal irrigation results, impacting crop yield and quality.

[0028] To address the above issues, the following technical questions are raised.

[0029] Please refer to Figures 1 to 3 This invention provides a water and fertilizer irrigation device for berry cultivation with adjustable spraying range, including an irrigation tank 1, a mixing assembly 2, a controller 3, a conveying assembly 4, and a nozzle 5. The mixing assembly 2 is fixedly installed inside the irrigation tank 1, the controller 3 is fixedly installed on the outer wall of the irrigation tank 1, the conveying assembly 4 is fixedly installed on the irrigation tank 1, and the bottom of the nozzle 5 is fixedly installed on the conveying assembly 4.

[0030] Specifically, the top of the irrigation tank 1 is provided with a first water inlet pipe 1.1 and a second water inlet pipe 1.2. The mixing assembly 2 includes a mixing motor 2.1, a mixing rod 2.2 and a mixing blade 2.3. The base of the mixing motor 2.1 is fixedly installed on the top of the irrigation tank 1.

The distribution pipe 4.5 is fixedly installed on the cross-laying pipe 4.4, and the top of the distribution pipe 4.5 is fixedly installed on the bottom of the spray pipe 6. The conveying assembly 4 also includes a first electric valve 4.6 and a second electric valve 4.7. The first electric valve 4.6 is fixedly installed on the main outlet pipe 4.3, and the second electric valve 4.7 is fixedly installed on the distribution pipe 4.5.

[0032] More specifically, the water spray pipe 6 has a converging channel 6.1 and a expanding channel 6.2 inside. A water spray core 6.3 is fixedly installed at the top of the inner part of the water spray pipe 6. A flow-driving plate 6.4 is fixedly installed inside the expanding channel 6.2. The flow-driving plate 6.4 is used to agitate the water flow. The power assembly 7 includes a power bracket 7.1, a power shaft 7.2, and an impeller 7.3. The power bracket 7.1 is fixedly installed on the inner wall of the water spray pipe 6. One end of the power shaft 7.2 is rotatably installed inside the power bracket 7.1. The impeller 7.3 is fixedly installed on the power shaft 7.2. The other end of the power shaft 7.2 extends out of the water spray pipe 6. The impeller 7.3 rotates along with the water inside the water spray pipe 6.

[0033] More specifically, the adjustment assembly 8 includes a guide rod 8.1, an adjustment box 8.2, a generator 8.3, and a battery 8.4. The bottom of the guide rod 8.1 is fixedly mounted on the top of the water spray pipe 6, the bottom of the adjustment box 8.2 is fixedly mounted on the top of the guide rod 8.1, and the generator 8.3 is fixedly mounted inside the adjustment box 8.2. The rotating shaft of the generator 8.3 is fixedly mounted on the end of the power shaft 7.2 away from the power bracket 7.1. The adjustment assembly 8 also includes a second signal receiver 8.5, a motor 8.6, a gear pair 8.7, a threaded rod 8.8, and an adjustment pressure plate 8.9. The second signal receiver 8.5 is fixedly mounted inside the adjustment box 8.2. At the top, the motor 8.6 is fixedly installed inside the top of the adjusting box 8.2. The input gear of the gear pair 8.7 is fixedly installed on the rotating shaft of the motor 8.6. The top of the threaded rod 8.8 is fixedly installed on the output gear of the gear pair 8.7. The bottom of the threaded rod 8.8 is rotatably installed on the top of the water spray pipe 6. The adjusting plate 8.9 is slidably installed on the guide rod 8.1. The adjusting plate 8.9 is threadedly installed on the threaded rod 8.8. The adjusting plate 8.9 adjusts the distance between itself and the top of the water spray pipe 6. Water is sprayed from the top of the water spray pipe 6, covering an area from far to near and from near to far. The adjusting plate 8.9 is a curved plate, which makes the water spray more even.

[0034] Furthermore, the operation is controlled by the controller 3. Water and chemicals are poured into the irrigation tank 1 through the first water inlet pipe 1.1 and the second water inlet pipe 1.2. The stirring motor 2.1 is started. The rotating shaft of the stirring motor 2.1 drives the stirring rod 2.2 to rotate. The rotation of the stirring rod 2.2 drives the stirring blade 2.3 to rotate. The rotation of the stirring blade 2.3 makes the water and chemicals in the irrigation tank 1 fully mixed.

[0035] Start the water pump 4.1. The water pump 4.1 draws water from the irrigation tank 1 through the water pumping pipe 4.2. The water enters the main outlet pipe 4.3, the horizontal pipe 4.4 and the branch pipe 4.5. By opening the first electric valve 4.6 and the second electric valve 4.7, water flows through the corresponding branch pipe 4.5. The nozzles 5 on the branch pipe 4.5 spray water to irrigate the berry plantation.

[0036] Water enters the spray pipe 6 from the water distribution pipe 4.5. The water passes through the converging channel 6.1, which drives the impeller 7.3 to rotate. The rotation of the impeller 7.3 drives the rotation of the power shaft 7.2. The water then flows around the flow plate 6.4, which thoroughly mixes the water and the agent. The water then enters the expanding channel 6.2 from the converging channel 6.1 and finally reaches the spray core 6.3 to be sprayed out.

[0037] The rotation of the power shaft 7.2 drives the generator 8.3, which in turn charges the battery 8.4. The battery 8.4 supplies power to the motor 8.6. The forward and reverse rotation of the motor 8.6 drives the gear pair 8.7, which in turn drives the threaded rod 8.8. The rotation of the threaded rod 8.8 causes the adjusting plate 8.9 to slide up and down along the guide rod 8.1. The adjusting plate 8.9 adjusts its distance from the top of the water spray pipe 6 according to the rotation of the motor 8.6. The adjusting plate 8.9 gradually moves closer to... Near the top of the water pipe 6, the adjusting plate 8.9 presses against the top water outlet of the water pipe 6, gradually increasing the pressure at the top water outlet of the water pipe 6. The water sprayed along the adjusting plate 8.9 travels further and further away from the top of the water pipe 6. As the adjusting plate 8.9 moves further away from the top water outlet of the water pipe 6, the pressure at the top water outlet of the water pipe 6 gradually decreases, and the water sprayed along the adjusting plate 8.9 travels closer and closer. This results in a dynamic spraying of water from the top of the water pipe 6, covering an area from far to near and from near to far, irrigating the berry plantation.

[0038] The storage battery 8.4 serves as the second signal receiver 8.5, which is connected to the first signal receiver 3.1 in real time. This enables the controller 3 to control the water sprayed from the nozzle 5 to spray dynamically from far to near and from near to far, thus irrigating the berry plantation.

[0039] The electric motor 8.6 operates intermittently to prevent insufficient power supply from the generator 8.3 to the battery 8.4.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
