Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and more particularly to an agricultural water-saving irrigation system and a water-saving irrigation method thereof. Background Art

[0002] Traditional irrigation methods such as flooding are seriously wasteful of water resources and are no longer able to adapt to the modern agricultural pursuit of efficient use of water resources. According to statistics, under flooding, the effective utilization rate of water is often less than 50%, and a large amount of water resources are lost due to evaporation and leakage during the field flooding process. While drip irrigation and micro-sprinkler irrigation are gradually being promoted as relatively water-saving irrigation methods, they still have many limitations in practical applications and need to be improved urgently.

[0003] Drip irrigation problems: Although drip irrigation is precise and water-saving, and can deliver water directly to the roots of crops to reduce water evaporation, the drippers are prone to clogging. Since the outlet of the dripper is extremely small, usually 0.5-2 mm, even tiny impurities in the water, such as a very small amount of silt, algae, microorganisms, etc., can easily cause clogging. Once blocked, it not only affects the uniformity of drip irrigation and causes water shortage for some crops, but also the work of troubleshooting and cleaning blocked drippers is cumbersome and consumes a lot of manpower and material resources. In addition, drip irrigation is local irrigation, and long-term use can easily lead to salt accumulation problems, especially in arid and semi-arid areas. If there is a lack of proper leaching measures, salt will accumulate around the roots of crops, endangering the health of the roots and affecting crop growth.

[0004] Disadvantages of micro-sprinkler irrigation: Micro-sprinkler irrigation can spread water evenly like rainfall, and also has the function of regulating the microclimate in the field, but it also has high requirements for water quality. The nozzle aperture is generally 2-4 mm. Although it is larger than the dripper, impurities in the water can still cause the nozzle to be blocked, resulting in uneven spraying. In addition, the equipment cost of the micro-sprinkler irrigation system is high, including nozzles, pipes, filters, booster pumps, etc. The purchase and installation costs are significantly higher than traditional irrigation methods. At the same time, micro-sprinkler irrigation is greatly affected by wind. In areas with strong winds, water droplets are blown away, irrigation water is unevenly distributed, and some crops do not get enough water, affecting the irrigation effect.

[0005] Different types of crops have different requirements for water demand, delivery height and irrigation methods at different stages of growth. For example, during the seedling stage of vegetables, the plants are short and the root system is shallow, so it is suitable to use low-altitude drip irrigation to accurately and gently supply water to the seedlings to prevent water flow impact and damage to the seedlings; when entering the vigorous growth period, the vegetables have lush branches and leaves, and it may be necessary to switch to micro-sprinkler irrigation to evenly sprinkle water on the leaves and around the plants at a higher height to ensure that all parts are fully hydrated. For example, in the case of fruit trees, the root system is not well developed in the young tree stage, so drip irrigation is conducive to precise water supply; in the mature tree stage, the crown is huge, and micro-sprinkler irrigation can better cover the crown range, regulate humidity, and promote fruit growth. However, the existing drip irrigation and micro-sprinkler irrigation equipment are mostly fixed modes, which are difficult to meet the dynamic needs of the entire crop growth process.

[0006] As agriculture moves towards mechanization, automation, and intelligence, traditional fixed-height, single-mode irrigation equipment cannot be efficiently integrated with the modern agricultural production system. On the one hand, precision agriculture requires precise control of irrigation based on the real-time growth status of crops, soil moisture, meteorological conditions, etc., and existing irrigation technology is difficult to achieve highly flexible adjustments; on the other hand, labor costs in agricultural production continue to rise, and new irrigation technologies that can reduce labor intensity and improve production efficiency are urgently needed. For example, in large-scale plantations, if the convenient conversion of drip irrigation and micro-sprinkler irrigation and highly automatic adjustment can be achieved, manual intervention can be greatly reduced, the degree of automation of irrigation operations can be improved, and it is in line with the trend of agricultural modernization.

[0007] In areas with complex terrain such as mountains and hills, the ground is undulating and it is difficult for traditional fixed-height irrigation equipment to ensure that irrigation water reaches crops evenly. In facility agriculture scenarios such as greenhouses and canopies, the spatial layout often changes with the crops planted, and the adaptability of irrigation height and methods is extremely high. Existing drip irrigation and micro-sprinkler irrigation technologies lack sufficient flexibility in these special scenarios and cannot give full play to their advantages of water saving and high efficiency. There is an urgent need for a drip irrigation and micro-sprinkler irrigation conversion technology with adjustable height to break the deadlock.

[0008] Therefore, how to provide an agricultural water-saving irrigation system and a water-saving irrigation method that can convert between sprinkler irrigation and drip irrigation, and has a simple and direct irrigation process and is more practical is an issue that technicians in this field urgently need to solve. Summary of the invention

[0009] In view of this, the present invention provides an agricultural water-saving irrigation system and a water-saving irrigation method thereof, aiming to solve one of the problems in the above-mentioned background technology, realize the mutual conversion between sprinkler irrigation and drip irrigation, and make the irrigation process simple, direct and more practical.

[0010] In order to achieve the above object, the present invention adopts the following technical solution:

[0011] An agricultural water-saving irrigation system and a water-saving irrigation method thereof, comprising:

[0012] A water tank, wherein a water pump is provided in the water tank;

[0016] Furthermore, the irrigation sprinkler assembly includes a drip irrigation head, a sprinkler irrigation head, a connecting body and a valve core, the connecting body is connected to the water supply pipe, a accommodating cavity is provided in the connecting body, the drip irrigation head is provided at one end of the connecting body, a drip irrigation channel is provided between the drip irrigation head and the accommodating cavity, the sprinkler irrigation head is provided at the other end of the connecting body, a sprinkler irrigation channel is provided between the sprinkler irrigation head and the accommodating cavity, the valve core is provided in the connecting body, a conical surface is provided on the top of the valve core, the conical surface is adapted to the sprinkler irrigation channel, a small shaft diameter section is provided at the bottom of the valve core, and the small shaft diameter section is adapted to the drip irrigation channel.

[0017] Furthermore, a limiting protrusion is provided at the bottom of the accommodating cavity, and an opening is provided on the limiting protrusion. The inner diameter of the opening of the limiting protrusion is smaller than the inner diameter of the valve core. The small shaft diameter section is located in the opening. A spring is sleeved on the small shaft diameter section. One end of the spring away from the small shaft diameter section is provided on the drip irrigation head.

[0018] Furthermore, two sides of the valve core are in contact with the interior of the connecting body, and through holes are provided on two sides of the valve core.

[0019] Furthermore, it also includes a pressure regulating component, which includes a throttle and a pressure regulator. A plurality of throttles are arranged on the water supply pipe, and the pressure regulator is arranged on the irrigation pipe.

[0020] Furthermore, one side of each of the clamping plates close to each other is provided as a friction layer.

[0021] An agricultural water-saving irrigation system and a water-saving irrigation method thereof specifically include the following steps:

[0022] Step 1: Height adjustment: adjust the bolts on the clamping plate to fix the water supply pipe on the support plate. According to the height of the crops, adjust the height of the irrigation pipe through the lifting cylinder. According to the state of the crops, determine whether to irrigate through sprinkler irrigation or drip irrigation.

[0024] Step 3: When drip irrigation is required, the water flow is controlled so that water with lower water pressure enters the connector through the irrigation pipe.

The conical surface on the top of the valve core leaves the sprinkler irrigation channel, and the connection between the connector and the sprinkler head is opened. Irrigation water with high pressure is sprinkled through the sprinkler head.

[0049] An agricultural water-saving irrigation system and a water-saving irrigation method thereof specifically include the following steps:

[0050] Step 1: Height adjustment: adjust the bolts 24 on the clamping plate 22 to fix the water supply pipe 3 on the support plate 21. According to the height of the crops, adjust the height of the irrigation pipe 4 through the lifting cylinder 1. According to the state of the crops, determine whether to irrigate by sprinkler irrigation or drip irrigation.
