Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, and more specifically, to a farmland irrigation device. Background Technology

[0002] Farmland irrigation, as a specialized term in agriculture, mostly refers to a method of watering crops. In order to achieve agricultural automation, irrigation devices are usually pre-buried in the land before planting crops. These devices can achieve the effect of automated irrigation for crops.

[0003] Current irrigation systems mainly consist of three parts: the main control unit (water pump, control instruments, intelligent controller), the water distribution network (main pipes and branch pipes), and the irrigation devices (sprinklers and support rods). When constructing an irrigation system, the main and branch pipes are typically buried in the ground according to the design drawings to form the water distribution network. Then, support rods are inserted into the ground, and sprinklers are installed on the support rods to form the irrigation devices. Water supply pipes are then used to connect the branch pipes and sprinklers, allowing water from the branch pipes to smoothly enter the sprinklers. Control instruments are then installed on the water pump, and an automated control system is integrated for remote control using an intelligent controller. Finally, the water pump and main pipe are connected, and the water pump is placed at the water source, thus completing the construction of the irrigation system.

[0004] When using irrigation equipment to irrigate the land, the intelligent controller controls the water pump to start, and the required water intake speed and water pressure are set. The water pump draws water from the water source into the main pipe, and the main pipe delivers the water to each branch pipe. The water is then delivered to the sprinkler heads through the water delivery pipes on the branch pipes, and the water is sprayed onto the land through the sprinkler heads, thereby achieving the effect of irrigating the farmland.

[0005] However, when water is delivered to the nozzle, although the filter screen inside the water pump can filter out most of the impurities in the water source (such as aquatic plants and silt), some impurities (such as algae and organic debris) will still pass through the filter screen and enter the nozzle, causing these impurities to accumulate inside the nozzle. When the impurities accumulate for a long time, the nozzle will be blocked by the impurities.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a farmland irrigation device that solves the problem that when water is delivered to the nozzle, some impurities accumulate inside the nozzle, and the nozzle will be blocked by impurities after a long period of accumulation.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a farmland irrigation device, including a support rod and a nozzle, wherein the nozzle includes a collection box threadedly connected to the support rod, the side wall of the collection box is provided with a water inlet for water supply, a connecting pipe that is connected to the inside of the collection box is fixedly connected to the collection box, a water spraying plate with an internal chamber is detachably connected to the top of the connecting pipe, a water outlet for water spraying is opened on the side wall of the water spraying plate, an installation port is opened on the top of the water spraying plate, an installation plate is detachably connected to the installation port, a connecting plate is snapped into the side wall of the installation plate, and a filter screen arranged in a tubular shape is fixedly connected to the bottom of the connecting plate.

[0009] The present invention is further configured such that: an installation ring is fixedly connected to the bottom of the water spray plate, and the installation ring is internally threaded to the connecting pipe.

[0010] The present invention is further configured such that: a fixing ring is fixedly connected to the bottom of the mounting plate, a limiting block is fixedly connected to the side wall of the mounting opening, and a limiting groove is provided on the outer wall of the fixing ring for the limiting block to slide, the limiting groove being L-shaped.

[0011] The present invention is further configured such that: a plurality of elastic sheets are fixedly connected to the bottom of the mounting plate, and a locking block is fixedly connected to the side wall of the elastic sheet; when the side walls of the mounting plate and the connecting plate are in contact with each other, the locking block and the side wall of the connecting plate are locked together, and at this time the elastic sheet is in a natural state.

[0012] The present invention is further configured such that a sealing rubber ring is fixedly connected to the bottom of the mounting plate.

[0013] The present invention is further configured such that: a limiting ring is fixedly connected to the inner wall of the connecting pipe, and when the mounting plate and the mounting port are installed together, the bottom of the filter screen and the top of the limiting ring are in contact with each other.

[0014] The present invention is further configured such that: a squeezing ring is fixedly connected to the outer wall of the water spray plate; a hose is fixedly connected to the water outlet; a movable ring is slidably connected to the outer wall of the connecting pipe; a plurality of L-shaped blocks are fixedly connected to the side wall of the movable ring; the L-shaped blocks are slidably connected to the outer wall of the water spray plate; the hose is in contact with the L-shaped blocks and the side wall of the squeezing ring respectively; an electric push rod is fixedly connected to the bottom of the water spray plate; and the output end of the electric push rod is fixedly connected to one of the L-shaped blocks.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this utility model and 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 utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] A farmland irrigation device, such as Figures 1-5 As shown, the device includes a support rod 1 and a nozzle. The nozzle includes a collection box 2 threadedly connected to the support rod 1. The side wall of the collection box 2 has a water inlet 3 for water supply. A connecting pipe 4, which is in communication with the inside of the collection box 2, is fixedly connected to the collection box 2. A spray plate 5 with an internal chamber is detachably connected to the top of the connecting pipe 4. A water outlet 6 for water supply is opened on the side wall of the spray plate 5. An installation port 7 is opened on the top of the spray plate 5. An installation plate 8 is detachably connected to the installation port 7. A connecting plate 9 is snapped onto the side wall of the installation plate 8. A filter screen 10 arranged in a tubular shape is fixedly connected to the bottom of the connecting plate 9, which makes it easy to disassemble the installation plate 8 and the filter screen 10 and to replace the filter screen 10.

[0027] When installing the support rod 1 and the nozzle, insert the support rod 1 into the ground, then connect the bottom of the collection box 2 and the support rod 1 with threads, then install the water spray plate 5 and the top of the connecting pipe 4 together, then take out the filter screen 10, and snap the connecting plate 9 on the filter screen 10 and the bottom of the mounting plate 8 together, then install the mounting plate 8 and the mounting port 7 together, and finally insert the water supply pipe used to deliver water to the collection box 2 into the water inlet 3, thus completing the installation of the support rod 1 and the nozzle.

[0028] When irrigating the land, water is delivered to the collection tank 2 through the water pipe. Simultaneously, the water, under its own pressure, enters the connecting pipe 4 and comes into contact with the filter screen 10. The filter screen 10 performs secondary filtration to remove smaller impurities from the water. To achieve ideal filtration and ensure smooth water flow, the filter screen 10 is preferably made of 304 stainless steel or corrosion-resistant engineering plastic, with a mesh size between 0.5 mm and 2 mm. This mesh size effectively intercepts common impurities in farmland irrigation water, such as algae and organic debris, while avoiding excessive water pressure loss and frequent clogging caused by excessively fine mesh, thus ensuring irrigation efficiency. After filtration, the water enters the sprinkler plate 5 and is sprayed out through the outlet 6, thereby irrigating the land.

[0029] After the land irrigation is completed, the impurities located at the filter screen 10 lose the impact force exerted on them by the water. Most of the impurities can fall downwards into the collection box 2 by gravity, or be removed together when the filter screen 10 is disassembled next time, thus effectively preventing clogging. The collection box 2 can collect the impurities. When it is necessary to clean the impurities in the collection box 2, simply remove the collection box 2 from the support rod 1 and the spray plate 5, and pour the impurities in the collection box 2 out through the connecting pipe 4 to complete the cleaning effect. In addition, the installation plate 8 makes it easy to remove the filter screen 10 from the spray plate 5, which is convenient for checking the condition of the filter screen 10 so that it can be cleaned or replaced in time.

[0030] Furthermore, a mounting ring 11 is fixedly connected to the bottom of the spray plate 5. The mounting ring 11 and the connecting pipe 4 are internally threaded, which further defines the connection method between the spray plate 5 and the connecting pipe 4. The threaded connection between the mounting ring 11 and the connecting pipe 4 makes it easy to install the spray plate 5 and the connecting pipe 4 together. At the same time, the threaded connection also makes the bottom of the connecting pipe 4 and the water outlet pipe fit more tightly, improving the sealing between the two.

[0031] A fixing ring 12 is fixedly connected to the bottom of the mounting plate 8, and a limiting block 13 is fixedly connected to the side wall of the mounting opening 7. A limiting groove 14, L-shaped, is provided on the outer wall of the fixing ring 12 to allow the limiting block 13 to slide. This further limits the installation method between the mounting plate 8 and the mounting opening 7. When installing the mounting plate 8 and the mounting opening 7, the limiting block 13 is inserted into the limiting ring 18, and the mounting plate 8 is rotated, causing the limiting block 13 to slide within the limiting groove 14. Because the limiting groove 14 is L-shaped, after the mounting plate 8 rotates, the mounting plate 8 and the mounting opening 7 are restricted by the limiting block 13 and the limiting groove 14, preventing them from separating. The mounting plate 8 is fixedly connected to the bottom of the mounting plate 8 with a sealing rubber ring 17. After the mounting plate 8 and the mounting port 7 are installed together, the mounting plate 8 and the side wall of the spray plate 5 will be more tightly abutted, improving the sealing effect between them. The inner wall of the connecting pipe 4 is fixedly connected with a limiting ring 18. When the mounting plate 8 and the mounting port 7 are installed together, the bottom of the filter screen 10 and the top of the limiting ring 18 will contact each other. After the mounting plate 8 and the mounting port 7 are installed together, water will be prevented from entering the spray plate 5 through the gap between the filter screen 10 and the inner wall of the connecting pipe 4, thus improving the filtration effect of the filter screen 10.

[0032] Several elastic pieces 15 are fixedly connected to the bottom of the mounting plate 8. A locking block 16 is fixedly connected to the side wall of each elastic piece 15. When the side walls of the mounting plate 8 and the connecting plate 9 are in contact with each other, the locking block 16 and the side wall of the connecting plate 9 are engaged. At this time, the elastic pieces 15 are in their natural state, further limiting the engagement method between the connecting plate 9 and the mounting plate 8. Both the locking block 16 and the elastic piece 15 are made of elastic metal sheets. When the connecting plate 9 and the mounting plate 8 are connected, the connecting plate 9 and the locking block 16 are engaged. Then, pressure is applied to the connecting plate 9, driving it to move towards the mounting plate 8. Simultaneously, the elastic piece 15 undergoes elastic deformation under the pressure. When the side walls of the connecting plate 9 and the mounting plate 8 are in contact with each other, the elastic piece 15 loses its restriction, deforms and recovers, and drives the locking block 16 back to its original position, engaging the locking block 16 and the side wall of the connecting plate 9. This completes the installation of the connecting plate 9 and the mounting plate 8.

[0033] like Figures 1-5 As shown, a squeezing ring 19 is fixedly connected to the outer wall of the spray plate 5, a hose 20 is fixedly connected to the outlet 6, a moving ring 21 is slidably connected to the outer wall of the connecting pipe 4, and several L-shaped blocks 22 are fixedly connected to the side wall of the moving ring 21. The L-shaped blocks 22 are slidably connected to the outer wall of the spray plate 5, and the hose 20 is in contact with the side wall of the L-shaped blocks 22 and the squeezing ring 19 respectively. An electric push rod 23 is fixedly connected to the bottom of the spray plate 5. The output end of the electric push rod 23 is fixedly connected to one of the L-shaped blocks 22. An automated control system can be implanted in the electric push rod 23 so that the staff can use the intelligent controller to control the state of the electric push rod 23. When water is sprayed outward through the outlet 6, the electric push rod 23 is activated, and the moving ring 21 is moved through the output end of the electric push rod 23. At the same time, the moving ring 21 moves the L-shaped block 22.

[0034] To achieve effective adjustment of the spraying distance, preferably, the electric actuator 23 is a miniature DC electric actuator with an IP65 waterproof rating, a rated thrust of 50N-100N, and a telescopic stroke of 10-20 mm. When the output end of the electric actuator 23 extends, it can effectively compress the hose 20 through the L-shaped block 22, reducing the cross-section of its outlet 6, thereby increasing the jet velocity and achieving a longer spraying distance. When it retracts, the hose 20 returns to its natural state, achieving short-distance, high-flow irrigation.

[0035] As can be seen from the above working process, the electric actuator 23 and the hose 20 are not only used to change the spraying distance, but more importantly, they work in synergy with the filter screen 10 installed in the chamber. Through the precise extension and retraction of the electric actuator 23, the degree of compression of the hose 20 by the L-shaped block 22 can be finely adjusted, thereby changing the cross-sectional size of the outlet 6. This compensates for the internal water pressure fluctuations caused by the presence of the filter screen 10. On the other hand, it can also actively adjust the jet speed according to irrigation needs, ultimately achieving a spraying effect that is both finely filtered and stable, efficient, and controllable at both near and far distances. This integrated 'filtration-compensation-control' design overcomes the shortcomings of existing technologies where the filtration and spraying devices are single-function and cannot work together.

[0036] The usage process of this utility model is as follows:

[0037] When installing the support rod 1 and the nozzle, insert the support rod 1 into the ground, then connect the bottom of the collection box 2 and the support rod 1 with threads, then install the water spray plate 5 and the top of the connecting pipe 4 together, then take out the filter screen 10, and snap the connecting plate 9 on the filter screen 10 and the bottom of the mounting plate 8 together, then install the mounting plate 8 and the mounting port 7 together, and finally insert the water supply pipe used to deliver water to the collection box 2 into the water inlet 3, thus completing the installation of the support rod 1 and the nozzle.

[0038] When irrigating the land, water is delivered to the collection box 2 through the water pipe. At the same time, the water enters the connecting pipe 4 due to its own water pressure and comes into contact with the filter screen 10. The filter screen 10 performs secondary filtration of small impurities in the water. After filtration, the water enters the water spray plate 5 and is sprayed out through the water outlet 6, thereby achieving the effect of irrigating the land.

[0039] After the land irrigation is completed, the impurities located at the filter screen 10 lose the impact force exerted by the water and fall downward into the collection box 2, where they can be collected. When it is necessary to clean the impurities in the collection box 2, simply remove the collection box 2 from the support rod 1 and the spray plate 5, and pour the impurities out through the connecting pipe 4 to complete the cleaning effect. Furthermore, the installation plate 8 makes it easy to remove the filter screen 10 from the spray plate 5, facilitating the inspection of the filter screen 10 and enabling timely cleaning or replacement.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
