Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to a water and fertilizer irrigation device for berry planting with an adjustable spraying range. Background Art

[0002] In modern agriculture, precision irrigation technology is of great significance for improving crop yield and quality. Especially in berry cultivation, since berry plants have high demands for water and nutrients and their root systems are relatively fragile, reasonable irrigation methods can significantly improve their growth conditions and yields. Therefore, berry planting water and fertilizer irrigation devices with adjustable spraying range play an important role in agricultural production. However, existing berry planting water and fertilizer irrigation devices have many shortcomings in actual application, especially in that the nozzles cannot freely adjust the coverage range of the water spray. These problems seriously affect the irrigation effect and the growth quality of crops.

[0003] Existing water and fertilizer irrigation devices for berry cultivation have obvious deficiencies in nozzle adjustment. The spraying range of the nozzle determines the uniformity of water and fertilizer distribution, which is particularly important for the growth of berry plants. However, existing nozzles can often only provide a fixed spraying range and cannot be freely adjusted according to actual conditions. For example, at different growth stages, berry plants have different demands for water and nutrients, and a fixed spraying range cannot meet these changing needs. During the seedling stage, the plant root system is small and requires centralized water supply; during the growth period, the plant root system expands and requires a wider distribution of water and fertilizer. Due to the lack of adjustment function, existing nozzles are unable to adapt to these changes, resulting in uneven water and fertilizer supply, affecting the growth and development of plants.

[0004] Existing water and fertilizer irrigation devices for berry cultivation also have shortcomings when dealing with different plots and terrain conditions. Berry cultivation is usually carried out in different plots, and the soil texture, slope and vegetation coverage of these plots are different, and the irrigation requirements are also different. However, the existing sprinkler heads cannot be adjusted according to the specific conditions of the plots, resulting in large differences in irrigation effects in different plots. For example, on slopes, a fixed spraying range may cause water to flow along the slope and fail to evenly cover the entire plot; on flat ground, a fixed spraying range may be too concentrated, resulting in some areas being too wet and other areas being too dry. This problem of not being able to freely adjust the spraying range makes it difficult to achieve the optimal irrigation effect, affecting the yield and quality of crops.

[0005] Existing irrigation systems for berry cultivation also have shortcomings 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 range can cause water and fertilizer to be blown away by the wind, preventing them from reaching the target area. In hot weather, a fixed spraying range can cause water to evaporate too quickly, preventing it from effectively moistening the soil. Existing sprinkler heads lack adjustment functions and cannot dynamically adjust to weather conditions, significantly reducing irrigation effectiveness. This not only wastes water resources but can also adversely affect plant growth.

[0006] Existing water and fertilizer irrigation devices for berry cultivation also have a large gap in the degree of automation. In large-scale cultivation, manually adjusting the spray range of the sprinkler nozzle is not only inefficient but also prone to human error. Although existing irrigation devices have partially achieved automated operation, there is still much room for improvement in adjustment accuracy and stability. For example, some equipment will experience delays and errors when automatically adjusting the spray range, resulting in unsatisfactory irrigation results. In addition, the low degree of automation of the equipment also increases the labor intensity of the operators, which is not conducive to the long-term development of the enterprise. In modern agricultural production, high-efficiency and high-quality irrigation are important guarantees to ensure crop growth, and existing irrigation devices are clearly insufficient in this regard.

[0007] Therefore, how to provide a water and fertilizer irrigation device for berry planting with an adjustable spray range is a problem that technicians in this field urgently need to solve. Summary of the Invention

[0030] Existing water and fertilizer irrigation devices for berry cultivation have obvious deficiencies in nozzle adjustment. The spraying range of the nozzle determines the uniformity of water and fertilizer distribution, which is particularly important for the growth of berry plants. However, existing nozzles can often only provide a fixed spraying range and cannot be freely adjusted according to actual conditions. For example, at different growth stages, berry plants have different demands for water and nutrients, and a fixed spraying range cannot meet these changing needs. In the seedling stage, the plant root system is small and requires centralized water supply. During the growth period, the plant root system expands and requires a wider distribution of water and fertilizer. Due to the lack of adjustment function, existing nozzles cannot adapt to these changes, resulting in uneven water and fertilizer supply, affecting the growth and development of plants.

[0031] Existing water and fertilizer irrigation devices for berry cultivation also have shortcomings when dealing with different plots and terrain conditions. Berry cultivation is usually carried out in different plots, and the soil texture, slope and vegetation coverage of these plots are different, and the irrigation requirements are also different. However, existing sprinkler heads cannot be adjusted according to the specific conditions of the plots, resulting in large differences in irrigation effects in different plots. For example, on slopes, a fixed spraying range may cause water to flow along the slope and fail to evenly cover the entire plot.

The adjusting pressing piece 8.9 is a curved plate, and the water spray is more evenly distributed.

[0038] Furthermore, the controller 3 is controlled to operate, pouring water and the chemical into the irrigation box 1 through the first water inlet pipe 1.1 and the second water inlet pipe 1.2, and starting the stirring motor 2.1. The rotation of the rotating shaft of the stirring motor 2.1 drives the stirring rod 2.2 to rotate, and the rotation of the stirring rod 2.2 drives the stirring blade 2.3 to rotate. The rotation of the stirring blade 2.3 fully mixes the water and the chemical in the irrigation box 1.

[0039] Start the water pump 4.1, which draws water from the irrigation box 1 through the pumping pipe 4.2. The water enters the main outlet pipe 4.3, the horizontal pipe 4.4, and the water distribution pipe 4.5.
