Description

Technical Field

[0001] This utility model relates to the field of drip irrigation equipment, and in particular to an adjustable pressure drip irrigation device for agricultural planting. Background Technology

[0002] With the global water shortage becoming increasingly severe, water-saving irrigation technology has become a key focus of modern agricultural development. Adjustable pressure drip irrigation systems, with their advantages of precise control, water conservation, high efficiency, and intelligent management, will be widely adopted in large-scale planting, facility agriculture, and precision agriculture, providing crucial support for sustainable agricultural development.

[0003] Most existing adjustable pressure drip irrigation systems for agricultural planting involve installing drip pipes around or above the plants, and using a booster device and pressure regulating valve to supply irrigation water into the drip pipes to meet the drip irrigation needs of crop seedlings. However, in actual use, irrigation water is mostly lake water or rainwater collected from storage. This water often contains a large amount of algae or silt and other impurities. When these impurities are sucked into the booster device along with the water flow, they can easily cause blockages and damage, thus affecting the normal use of the drip irrigation system. Therefore, an adjustable pressure drip irrigation system for agricultural planting is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable pressure drip irrigation device for agricultural planting, aiming to improve the problem that impurities in irrigation water can easily cause blockage and damage to the drip irrigation device in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable pressure drip irrigation device for agricultural planting includes a housing, a shell fixedly connected to the outer side of the housing, a connection port fixedly connected to the left side of the housing, a connecting pipe fixedly connected to the right side of the housing, the other end of the connecting pipe fixedly connected to the middle of the housing, a filter plate slidably connected to the middle of the shell, a limiting component installed between the filter plate and the shell, a locking block fixedly connected to the front end of the filter plate, a sleeve fixedly connected to the front side of the shell, a sliding rod slidably connected to the middle of the sleeve, a push plate fixedly connected to the top of the sliding rod, an elastic component installed in the middle of the sleeve, a spring rod fixedly connected to the middle of the push plate, a water supply pipe fixedly connected to the middle of the housing, and a nozzle installed in the middle of the water supply pipe.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a limiting block, which is fixedly connected to the outside of the filter plate. A limiting groove is formed in the middle of the housing, and the limiting block is slidably connected to the middle of the limiting groove.

[0012] As a further description of the above technical solution:

[0013] A slot is provided in the middle of the housing, and the locking block is slidably connected to the middle of the slot;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when in use, the water pipe is connected to the connector, and the irrigation water is first input into the housing. Under the action of the filter plate in the housing, the input water can be filtered, so that impurities are separated from the water, thereby avoiding damage to the pressurization equipment inside the housing by impurities. At the same time, after a long period of filtration, the push plate is pushed upward, so that the spring rod in the push plate separates from the locking block, so that the locking block can drive the filter plate out from the middle of the housing, ensuring the filtration effect of the filter plate.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3An embodiment of this utility model provides an adjustable pressure drip irrigation device for agricultural planting, comprising a shell 1, a shell 2 fixedly connected to the outer side of the shell 1, a connection port 3 fixedly connected to the left side of the shell 2, a connection pipe 11 fixedly connected to the right side of the shell 1, the other end of the connection pipe 11 fixedly connected to the middle of the shell 1, a filter plate 15 slidably connected to the middle of the shell 2, a limiting component installed between the filter plate 15 and the shell 2, the limiting component including a limiting block 16, the limiting block 16 fixedly connected to the outer side of the filter plate 15, a limiting groove 10 opened in the middle of the shell 2, and the limiting block 16 slidably connected to the middle of the limiting groove 10. When in use, connect the water pipe to the connector 3 to input irrigation water into the housing 2. The input water will fall on the top of the filter plate 15. Under the action of the filter plate 15, the water can be filtered, so that impurities can be separated from the water, thereby preventing impurities from damaging the pressurization equipment inside the housing 1. At the same time, under the action of the limiting block 16 and the limiting groove 10, not only is the stability of the filter plate 15 in the housing 2 ensured, but the sealing effect between the filter plate 15 and the housing 2 is also improved, preventing impurities from falling into the bottom of the housing 2 through the gaps.

[0034] Reference Figure 1 , Figure 2 and Figure 4A locking block 4 is fixedly connected to the front end of the filter plate 15, and a pull rod 18 is fixedly connected to the front side of the locking block 4. A sleeve 5 is fixedly connected to the front side of the housing 2. A sliding rod 13 is slidably connected to the middle of the sleeve 5. A 14 is fixedly connected to the top of the sliding rod 13. A push plate 12 is fixedly connected to the other end of the sliding rod 13. An elastic component is installed in the middle of the sleeve 5. A spring rod 21 is fixedly connected to the middle of the push plate 12. A water supply pipe 6 is fixedly connected to the middle of the housing 1. A nozzle 7 is installed in the middle. The elastic component includes a stop block 19, which is fixedly connected to the outer periphery of the slide rod 13. A compression spring 20 is sleeved on the outer periphery of the slide rod 13. A slot 9 is opened in the middle of the housing 2. A block 4 is slidably connected in the middle of the slot 9. A groove 28 is opened on the front side of the housing 2. A rubber ring 17 is fixedly connected to the side of the block 4 near the housing 2. The rubber ring 17 is in contact with the inner wall of the groove 28. The stop block 19 and the compression spring 20 are located in the middle of the sleeve 5. After prolonged filtration, the push plate 12 is pushed upwards. As the push plate 12 is lifted, the spring rod 21 in the middle of the push plate 12 retracts under the guidance of the groove 28, allowing the spring rod 21 to separate from the locking block 4. This allows the filter plate 15 to be pulled out from the middle of the housing 2 when the locking block 4 is pulled by the pull rod 18, ensuring the filtration effect of the filter plate 15. At the same time, when the push plate 12 is lifted, it will drive the slide rod 13, causing the slide rod 13 to drive the stop block 19 to squeeze the compression spring 20. After the filter plate 15 is inserted into the housing 2, the push plate 12 is released and pushed by the compression spring 20, allowing the push plate 12 to return to its original position. At the same time, the spring rod 21 will squeeze the locking block 4, allowing the rubber ring 17 to fit tightly against the inner wall of the groove 9, thereby ensuring the seal between the locking block 4 and the housing 2 and preventing irrigation water from seeping out through the gaps.

[0035] Reference Figure 1 and Figure 5 A round rod 23 is fixedly connected to the middle of the nozzle 7, and a round block 25 is fixedly connected to the other end of the round rod 23. A movable block 24 is slidably connected to the outer periphery of the round rod 23. A strong spring 27 is sleeved on the outer periphery of the round rod 23. A connecting rod 26 is fixedly connected to the outer side of the movable block 24. A stop block 22 is fixedly connected to the other end of the connecting rod 26. A filter screen 8 is fixedly connected to the middle of the nozzle 7. During use, the filter screen 8 prevents large amounts of soil from entering the middle of the nozzle 7. At the same time, the water pressure squeezes the baffle 22, causing the edge of the baffle 22 to separate from the inner wall of the nozzle 7. The baffle 22 drives the connecting rod 26 to move the movable block 24 around the outer circumference of the round rod 23, allowing the movable block 24 to squeeze the strong spring 27 around the round rod 23. When watering stops, the strong spring 27 pushes the movable block 24, thereby causing the baffle 22 to reset, ensuring that soil does not enter the water pipe 6 through the nozzle 7 and cause siltation. Thus, when watering stops, soil will not flow back into the outer casing 1 with the water.

[0036] Working principle: When in use, connect the water pipe to the connection port 3. The irrigation water will first be input into the housing 2. Under the action of the filter plate 15 in the housing 2, the input water can be filtered. At the same time, under the action of the limiting block 16 and the limiting groove 10, not only is the stability of the filter plate 15 in the housing 2 ensured, but the sealing effect between the filter plate 15 and the housing 2 is also improved, so that impurities are separated from water, thereby avoiding damage to the pressurization equipment inside the housing 1 caused by impurities. After a long period of filtration, push the push plate 12 upward, so that the spring rod 21 in the push plate 12 separates from the locking block 4, so that the locking block 4 can drive the filter plate 15 to be pulled out from the middle of the housing 2, ensuring the filtration effect of the filter plate 15.

[0037] During use, the irrigation water, under pressure, squeezes the baffle 22, causing the edge of the baffle 22 to separate from the inner wall of the nozzle 7. The baffle 22 drives the connecting rod 26 to drive the movable block 24 to slide around the outer periphery of the round rod 23, so that the movable block 24 can squeeze the strong spring 27 on the outer periphery of the round rod 23. When irrigation stops, the strong spring 27 will drive the baffle 22 to reset, so as to ensure that the soil will not enter the water pipe 6 through the nozzle 7 and cause siltation, so that the soil will not flow back into the outer shell 1 with the water when irrigation stops.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
