Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to a water-saving irrigation device for farmland construction. Background Technology

[0002] The development of agricultural irrigation technology has always revolved around the core goal of efficient water resource utilization, undergoing a historic leap from extensive flood irrigation to precise regulation. Traditional irrigation methods, such as flood irrigation and furrow irrigation, while playing a vital role in agricultural civilization, have resulted in severe water waste due to the practice of "irrigating the soil but not the roots," with an average water utilization rate per mu (unit of land area) consistently below 40%, and are prone to causing ecological problems such as soil compaction and salinization. With the intensification of global climate change, the expansion of arid and water-scarce areas, and the advancement of my country's water management policy of "prioritizing water conservation and spatial balance," the development of efficient water-saving irrigation technology has become an inevitable choice for agricultural modernization.

[0003] Water utilization can be increased to 70%-80% through pipeline water delivery and precise water control. For example, sprinkler irrigation technology disperses water into fine droplets through pressurized pipelines and sprays them evenly, saving 30%-50% of water compared to traditional flood irrigation. It also provides cooling and dust removal functions and is widely used in field crops and garden irrigation. Drip irrigation technology delivers water directly to the crop roots through drippers, saving more than 60% of water, and is especially suitable for fruit trees, greenhouse vegetables and other cash crops in arid areas.

[0004] However, the sprinkler heads mentioned above are mostly exposed. Since exposed sprinkler heads lack effective protective measures, once they become clogged, a lot of manpower is required to disassemble and clean them, or even replace the sprinkler head parts. During maintenance, irrigation operations need to be interrupted, and additional water resources may be lost due to system draining and pipeline flushing, resulting in the loss of manpower and water resources. Utility Model Content

[0005] The purpose of this invention is to address the problem that exposed sprinkler heads in the prior art lack effective protective measures. Once a blockage occurs, a lot of manpower is required for disassembly and cleaning, and even replacement of sprinkler head components. During maintenance, irrigation operations need to be interrupted, and additional water resources may be lost due to system dredging, pipe flushing, and other operations, resulting in the loss of both manpower and water resources.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a water-saving irrigation device for farmland construction, comprising:

[0007] An irrigation pipe is provided with a fixed plate at the top and an input interface at the bottom. An irrigation nozzle is slidably connected inside the irrigation pipe, and multiple evenly distributed spray nozzles are provided on the outer wall of the upper end of the irrigation nozzle.

[0008] A sleeve is rotatably connected to the outer circumference of the irrigation pipe, and a sliding seal is formed between the sleeve and the irrigation pipe;

[0009] A drive disk, which is fixedly connected to the top of the sleeve;

[0010] Four baffles are located at the four corners of the fixed plate, and their lower ends are slidably connected to the fixed plate.

[0011] A drive mechanism is disposed between the fixed disk and the drive disk, and the drive mechanism is synchronously connected to the plurality of the baffles.

[0012] A synchronization mechanism is provided between the sleeve and the irrigation nozzle, and the synchronization mechanism is connected to the drive mechanism for transmission.

[0013] In a preferred embodiment, the drive mechanism includes:

[0014] A sliding rod is provided corresponding to each of the shields, and the sliding rod is fixedly connected to the lower rear end of the corresponding shield. The shield can slide to cover or expose the spray area.

[0015] The fixed plate has a straight groove corresponding to each baffle, and the sliding rod is slidably connected inside its corresponding straight groove.

[0016] The drive disc has an arc-shaped groove corresponding to each baffle, and the bottom end of the sliding rod passes through the straight groove and is slidably connected inside its corresponding arc-shaped groove.

[0017] In a preferred embodiment, two symmetrically distributed sliding grooves are provided at both ends of the irrigation pipe, and sliding pins are fixedly connected to both ends of the irrigation nozzle at the corresponding sliding grooves. The sliding pins are slidably connected inside their respective sliding grooves.

[0018] In a preferred embodiment, the synchronization mechanism includes two guide grooves formed on the inner wall of the sleeve corresponding to two sliding pins, with the ends of the sliding pins passing through the sliding grooves and slidably connected inside their respective guide grooves.

[0019] In a preferred embodiment, a filter screen is fixedly connected to the inner wall of the lower end of the irrigation pipe, which serves to block the mud and sand in the water flow of the irrigation nozzle and prevent the mud and sand from clogging the irrigation nozzle.

[0020] In a preferred embodiment, a fixing sleeve is fixedly connected to the lower end of the irrigation pipe, a fixing block is fixedly connected to the side end of the fixing sleeve, and a horizontal mounting plate is fixedly connected to the end of the fixing block for fixed connection with an external vertical mounting frame.

[0021] In a preferred embodiment, the bottom end of the irrigation pipe is fixedly connected to a vertical and horizontal mounting plate for fixed connection with an external horizontal mounting frame.

[0022] In a preferred embodiment, the bottom end of the irrigation pipe is fixedly connected to a vertical and horizontal mounting plate, both of which have pre-drilled mounting holes.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] This utility model includes components such as a drive plate, mounting plate, sleeve, linear slide groove, arc slide groove, and guide groove. It enables the automatic opening of a shield during sprinkler irrigation, raising the irrigation nozzles for spraying. After spraying stops, the irrigation nozzles automatically descend, and the shield closes. No manual control is required. The shield forms a movable, concealed nozzle structure that automatically opens during irrigation and automatically closes after irrigation stops, protecting the irrigation nozzles, reducing the risk of clogging, and minimizing manpower and water resource consumption.

Detailed Implementation

[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] Please see Figure 1-5 This utility model provides a technical solution: a water-saving irrigation device for farmland construction.

[0034] An irrigation pipe 1 is provided, with a fixed plate 8 fixedly connected to the top end of the irrigation pipe 1. An input interface is provided at the bottom end of the irrigation pipe 1, which is connected to an external water input pipe through a flexible hose to receive external water input. An irrigation nozzle 14 is slidably connected inside the irrigation pipe 1. Multiple evenly distributed spray nozzles 15 are provided on the upper outer wall of the irrigation nozzle 14. The spray nozzles 15 function to spray the water in the irrigation pipe 1 in a 360-degree manner. A filter screen 19 is fixedly connected to the lower inner wall of the irrigation pipe 1 to block the mud and sand in the water flow, thereby reducing the impact of mud and sand in the water flow on the irrigation nozzle 14.

[0035] Sleeve 2 is rotatably connected to the outer circumference of irrigation pipe 1, and there is a sliding seal between sleeve 2 and irrigation pipe 1 to prevent water leakage and waste of water resources.

[0036] After the water supply is connected to the external water supply pipe through the input interface via a flexible hose, and water is supplied into the irrigation cylinder 1, the lower end of the irrigation nozzle 14 is pushed upward by the water flow and moves in a straight line. After being pushed out of the top of the irrigation cylinder 1, the sprinkler nozzle 15 is no longer obstructed and can then perform sprinkler irrigation. When the water supply is stopped, the lifting force of the water flow on the irrigation nozzle 14 disappears, and it falls back into the irrigation cylinder 1.

[0037] Drive disk 9 is fixedly connected to the top of sleeve 2;

[0038] Four baffles 10 are located at the four corners of the fixed plate 8, and their lower ends are slidably connected to the fixed plate 8. The baffles 10 can close the upper end of the irrigation pipe 1 to achieve the function of blocking. When separated, the spraying area can be exposed, which is convenient for the extension of the irrigation nozzle 14.

[0039] A drive mechanism is located between a fixed disk 8 and a drive disk 9, and the drive mechanism is synchronously connected to multiple baffles 10.

[0040] The drive mechanism includes:

[0041] A sliding rod 12 is provided corresponding to each of the baffles 10, and the sliding rod 12 is fixedly connected to the lower rear end of the baffle 10 corresponding to it.

[0042] The fixed plate 8 is provided with a linear groove 11 corresponding to each of the baffles 10. The sliding rod 12 is slidably connected inside its corresponding linear groove 11. The linear groove 11 serves to guide and limit the movement direction of the sliding rod 12.

[0043] The drive disc 9 has an arc-shaped groove 13 corresponding to each of the baffles 10. The bottom end of the sliding rod 12 passes through the straight groove 11 and is slidably connected inside its corresponding arc-shaped groove 13.

[0044] The above-mentioned driving structure realizes the function of controlling the baffle 10. The specific movement mode is as follows: the sleeve 2 rotates, and when the guide groove 18 rotates, it drives the drive disk 9 to rotate. When the drive disk 9 rotates, it drives multiple sliding rods 12 to move synchronously through the arc-shaped slide groove 13. The linear slide groove 11 limits the movement direction of the sliding rods 12, so that when the drive disk 9 rotates, it drives the baffle 10 to move linearly along the linear slide groove 11. That is, the rotation of the sleeve 2 is realized, which drives multiple baffles 10 to close or open, thus realizing the function of controlling the baffle 10.

[0045] A synchronization mechanism is installed between the sleeve 2 and the irrigation nozzle 14, and the synchronization mechanism is connected to the drive mechanism.

[0046] The synchronization mechanism includes two guide grooves 18 on the inner wall of the sleeve 2 corresponding to two sliding pins 16. The guide grooves 18 serve both as the passage position of the sliding pins 16 and as the limiting function for the lifting height of the irrigation nozzles 14. The ends of the sliding pins 16 pass through the sliding grooves 17 and are slidably connected inside their corresponding guide grooves 18.

[0047] The above-mentioned synchronization mechanism enables the synchronous control of the raising and lowering of the sleeve 2 when the irrigation nozzle 14 is raised and lowered. The specific movement method is as follows:

[0048] When the irrigation nozzle 14 is raised or lowered, the sliding pins 16 at both ends slide along the sliding groove 17 and simultaneously squeeze the guide groove 18. The front end of the guide groove 18 is arc-shaped, which can cause the sleeve 2 to rotate during the squeezing process. Thus, the rotation of the sleeve 2 can be controlled by raising or lowering the irrigation nozzle 14.

[0049] Through the coordination of the aforementioned synchronization mechanism and drive mechanism, the baffle plate 14 can close the upper end of the irrigation pipe 1 when the irrigation nozzle 14 is not extended, thus achieving the function of blocking. When the irrigation nozzle 14 is extended, the baffle plate 10 can separate to expose the spraying area, facilitating the extension of the irrigation nozzle 14. When not spraying, the baffle plate 14 can also protect the irrigation nozzle 15 from the influence of the air environment, prevent oxidation and aging of the internal components of the spray nozzle 15, ensure the performance of the spray nozzle 15, and extend the service life of the spray nozzle 15.

[0050] This application has two installation methods: Embodiment 1, which is installed vertically on the side, and Embodiment 2, which is installed horizontally on the bottom.

[0051] Example 1:

[0052] The lower end of the irrigation pipe 1 is fixedly connected to a fixing sleeve 3, the side end of the fixing sleeve 3 is fixedly connected to a fixing block 4, and the end of the fixing block 4 is fixedly connected to a horizontal mounting plate 5 for fixed connection with an external vertical mounting frame. This embodiment can be fixedly installed on vertical structures such as vertical square steel and vertical mounting frame.

[0053] Example 2: A vertical and horizontal mounting plate 7 is fixedly connected to the bottom end of the irrigation pipe 1 for fixed connection with an external horizontal mounting frame; this example can be installed on horizontal mounting structures such as horizontal steel beams and horizontal pipe connection frames;

[0054] In addition, both the horizontal mounting plate 5 and the vertical mounting plate 7 have pre-drilled mounting holes 6 to facilitate fixed connection work.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
