Description

Technical Field

[0001] This utility model relates to the field of agricultural water conservancy and irrigation technology, specifically to an irrigation device for farmland water conservancy. Background Technology

[0002] In fruit tree planting, flood irrigation is often used, which involves introducing water into the orchard surface and allowing it to spread naturally along the rows and tree basins and infiltrate downwards to moisten the entire root system. This method can create a deep soil moisture zone, meeting the water needs of fruit trees with their wide root distribution and deep penetration into the soil. At the same time, it has lower requirements for terrain flatness and irrigation facilities, low construction and maintenance costs, and is easy to operate. It is suitable for traditional orchards with large row spacing and management that relies mainly on manual experience.

[0003] However, when using flood irrigation, the water pipe outlets are usually placed haphazardly on the ground, with the outlets directly contacting the ground. This results in high local flow velocities, which can easily cause the soil surface to be eroded, compacted, or form trenches, affecting soil permeability. In view of this, we propose an irrigation device for farmland water conservancy. Utility Model Content

[0004] The purpose of this invention is to provide an irrigation device for farmland water conservancy to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irrigation device for farmland water conservancy, comprising a pipe body, a nozzle fixedly connected to the end face of the pipe body, a support assembly provided on the outer wall of the nozzle, the support assembly including a rotating sleeve welded to the outer wall of the nozzle, a retaining sleeve fixedly connected to the outer wall of the rotating sleeve, a rotating rod inserted into the outer wall of the rotating sleeve, a retaining block fixedly connected to the outer wall of the rotating rod, a support leg hinged to the outer wall of the rotating rod, a hinge rod hinged to the side wall of the support leg, and a dispersion assembly provided at the end of the nozzle away from the pipe body.

[0006] Preferably, there are two sets of outriggers and hinge rods. The ends of the two sets of hinge rods away from the outriggers are hinged to each other. One set of outriggers is fixedly connected to the rotating rod. The maximum opening and closing distance of the outriggers is limited by the two sets of hinge rods.

[0007] Preferably, the locking block is inserted into the rotating sleeve, and the inner wall of the locking sleeve is movably connected to the support leg. The locking sleeve houses the support leg and the hinge rod. Pulling out the rotating rod releases the locking block from the rotating sleeve. At this time, the rotating rod can be rotated to drive the support leg to rotate, so that the support leg is perpendicular to the axis of the nozzle. Then, the rotating rod and the locking block are pushed to lock the locking block into the rotating sleeve.

[0008] Preferably, the dispersing component includes a cover rotatably connected to the end face of the pipe body, and the side wall of the cover has a slot, through which water can be discharged from the nozzle.

[0009] Preferably, the number of slots is set to several, and the several slots are divided into two groups. The two groups of slots are respectively set above and below the cover, so as to disperse the water flow and prevent the water flow from washing away one place.

[0010] Preferably, a handle is rotatably connected to the side wall of the cover, and an adjustment cover is fixedly connected to the end face of the handle. The adjustment cover fits against the inner wall of the cover, and the adjustment cover is rotated by rotating the handle.

[0011] Preferably, the side wall of the adjusting cover is provided with a through opening and the side wall of the adjusting cover is provided with a second slot. By rotating the handle and the adjusting cover, the positions of the through opening and the second slot can be changed.

[0012] Preferably, the second slot coincides with the upper set of slots, and the second slot is staggered with the lower set of slots, so that the opening coincides with the upper set of slots and the second slot is located below. At this time, the second slot and the lower set of slots are staggered, and the water can only be discharged through the upper set of slots and the opening, avoiding the water from being discharged from the lower set of slots and impacting the ground.

[0013] Compared with the prior art, this utility model provides an irrigation device for farmland water conservancy, which has the following beneficial effects: 1. This irrigation device for farmland water conservancy, through its supporting and dispersing components, ensures that the sprinkler head is stably supported on the ground during use, preventing displacement or tipping due to direct contact with the ground. This improves the stability and safety of irrigation operations. The locking structure of the locking block and rotating sleeve reliably locks the outriggers in their extended and retracted states, facilitating quick adjustments to the usage state and preventing accidental retraction of the outriggers due to vibration or water pressure changes during irrigation. The slot allows water to be dispersed and discharged in different directions, achieving uniform water flow and preventing concentrated water flow from scouring the same location. This reduces erosion and damage to the surface soil and helps maintain the integrity of the soil structure.

[0014] 2. This irrigation device for farmland water conservancy, through the set adjustment cover, when the handle is turned, the water flow cannot be discharged through the lower set of slots, avoiding the water flow from spraying downwards and directly impacting the bottom of the ground. Continuing to turn the handle can also change the correspondence between the through-hole and slot two relative to slot one, so as to achieve different water distribution modes, flexibly control the water outlet direction and water outlet area of ​​the nozzle, improve the adaptability and adjustability of the irrigation device, and meet different irrigation needs.

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: an irrigation device for farmland water conservancy, including a pipe body 1, a nozzle 2 fixedly connected to the end face of the pipe body 1, a support assembly 3 provided on the outer wall of the nozzle 2, the support assembly 3 including a rotating sleeve 301 welded to the outer wall of the nozzle 2, a retaining sleeve 302 fixedly connected to the outer wall of the rotating sleeve 301, a rotating rod 303 inserted into the outer wall of the rotating sleeve 301, a retaining block 304 fixedly connected to the outer wall of the rotating rod 303, a support leg 305 hinged to the outer wall of the rotating rod 303, a hinge rod 306 hinged to the side wall of the support leg 305, and a dispersing assembly 4 provided at the end of the nozzle 2 away from the pipe body 1.

[0018] In one embodiment of this utility model, two sets of support legs 305 and hinge rods 306 are provided. The ends of the two sets of hinge rods 306 away from the support legs 305 are hinged to each other. One set of support legs 305 is fixedly connected to the rotating rod 303. The maximum opening and closing distance of the support legs 305 is limited by the two sets of hinge rods 306. The locking block 304 is inserted into the rotating sleeve 301. The inner wall of the locking sleeve 302 is movably connected to the support legs 305. The locking sleeve 302 houses the support legs 305 and the hinge rods 306. Pulling out the rotating rod 303 releases the locking block 304 from the rotating sleeve 301. At this time, the rotating rod 303 can be rotated to drive the support legs 305 to rotate, so that the support legs 305 are perpendicular to the axis of the nozzle 2. Then, the rotating rod 303 and the locking block 304 are pushed to lock the locking block 304 into the rotating sleeve 301.

[0019] The dispersing component 4 includes a cover 401 rotatably connected to the end face of the pipe body 1. The side wall of the cover 401 is provided with a slot 402, through which water can be discharged from the nozzle 2. The number of slots 402 is set to several, and the slots 402 are divided into two groups. The two groups of slots 402 are respectively set above and below the cover 401. The water flow is dispersed by the slots 402 to prevent the water flow from washing away one place.

[0020] First, connect the pipe body 1 to the external water supply pipeline so that water flows into the pipe body 1 and is delivered to the nozzle 2. When it is necessary to support and fix the nozzle 2, the operator pulls the rotating rod 303 outward so that the locking block 304 is disengaged from the locking state of the rotating sleeve 301. At this time, the rotating rod 303 can rotate relative to the rotating sleeve 301. By rotating the rotating rod 303, a set of support legs 305 fixedly connected to it will rotate synchronously, so that the support legs 305 unfold and finally become perpendicular to the axis of the nozzle 2.

[0021] During the deployment of the outrigger 305, the two sets of hinge rods 306 limit the deployment angle of the outrigger 305 to prevent it from opening excessively and ensure the stability of the overall structure. After the outrigger 305 is deployed to its final position, the operator pushes the rotating rod 303 again, causing the locking block 304 to re-engage with the rotating sleeve 301, thus limiting and fixing the rotating rod 303. This allows the outrigger 305 to stably support the sprinkler head 2, ensuring that the sprinkler head 2 is stably supported on the ground during use and preventing it from directly contacting the ground and shifting or tipping over. This improves the stability and safety of irrigation operations. The locking structure between the locking block 304 and the rotating sleeve 301 reliably locks the outrigger 305 in its deployed and retracted states. This facilitates quick adjustment of the usage state and prevents the outrigger 305 from accidentally retracting due to vibration or water pressure changes during irrigation, improving the reliability of the overall structure. In the undeployed state, the outrigger 305 and the hinge rod 306 can be stored in the sleeve 302 for easy storage and transportation of the device.

[0022] When water flows through the pipe body 1 and into the nozzle 2, the water further enters the cover 401 that is rotatably connected to the end face of the pipe body 1, and is discharged through several slots 402 opened on the side wall of the cover 401. The slots 402 are arranged in two groups, upper and lower, so that the water is dispersed and discharged in different directions, thereby achieving uniform dispersion of the water flow, avoiding the water flow from concentrating and scouring the same position, thus reducing the erosion and damage to the surface soil, and helping to maintain the integrity of the soil structure.

[0023] In addition, a handle 5 is rotatably connected to the side wall of the cover 401, and an adjusting cover 6 is fixedly connected to the end face of the handle 5. The adjusting cover 6 is in contact with the inner wall of the cover 401. The adjusting cover 6 is rotated by rotating the handle 5. The side wall of the adjusting cover 6 is provided with a through-hole 7 and a slot 8. By rotating the handle 5 and the adjusting cover 6, the positions of the through-hole 7 and the slot 8 are changed. The slot 8 coincides with the upper set of slots 402, and the slot 8 is staggered with the lower set of slots 402, so that the through-hole 7 coincides with the upper set of slots 402 and the slot 8 is located at the bottom. At this time, the slot 8 and the lower set of slots 402 are staggered. At this time, the water can only be discharged through the upper set of slots 402 and the through-hole 7, avoiding the water from being discharged from the lower set of slots 402 and impacting the ground.

[0024] As the handle 5 is rotated, the positions of the through-hole 7 and the second slot 8 relative to the first slot 402 on the side wall of the cover 401 change. In one working state, by rotating the handle 5, the second slot 8 and the first slot 402 on the lower part of the cover 401 are staggered, while the through-hole 7 and the first slot 402 on the upper part of the cover 401 are overlapped. In this state, the water flows from the pipe 1 into the nozzle 2 and then into the interior of the cover 401. It can only be discharged through the through-hole 7 and the first slot 402 that overlaps with it, but cannot be discharged through the first slot 402 on the lower part. This avoids the water from being sprayed downwards and directly impacting the bottom of the ground. By continuing to rotate the handle 5, the correspondence between the through-hole 7 and the second slot 8 relative to the first slot 402 can be changed to achieve different water distribution patterns. This allows for flexible control of the water outlet direction and area of ​​the nozzle 2, improving the adaptability and adjustability of the irrigation device and meeting different irrigation needs.

[0025] In this invention, during use, the pipe body 1 is connected to an external water supply pipeline, and water flows through the pipe body 1 to the nozzle 2. By pulling and rotating the rotating rod 303, the locking block 304 is disengaged from the rotating sleeve 301, causing the support leg 305, which is fixedly connected to the rotating rod 303, to unfold. Under the limiting action of the hinge rod 306, the support leg 305 is perpendicular to the axis of the nozzle 2. Subsequently, the locking block 304 re-engages with the rotating sleeve 301 to achieve fixed support for the support leg 305. After the water flows into the nozzle 2, it enters the cover 401 and is discharged through the slot 402 provided on the side wall of the cover 401. Rotating the handle 5 causes the adjusting cover 6 to rotate, causing the position of the through port 7 and the slot 8 relative to the slot 402 to change. Under a specific state, water is only allowed to be discharged through the upper slot 402 and through port 7, thereby achieving adjustment of the water outlet direction and water distribution of the nozzle 2.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
