Description

Technical Field

[0001] This utility model belongs to the field of wheat cultivation, and specifically relates to a uniform irrigation device for cold-resistant wheat cultivation. Background Technology

[0002] In agricultural production, cold-resistant wheat, due to its ability to adapt to low-temperature environments, has become an important grain crop in northern regions. Its growth process requires a high degree of uniformity in water supply, and proper irrigation is key to ensuring yield and quality. With the development of agricultural mechanization, various irrigation equipment has been gradually applied to wheat cultivation, enabling targeted water delivery. Currently, irrigation technology can adjust the water supply according to the crop growth stage, providing appropriate water support for different growth stages of cold-resistant wheat (such as the jointing stage and the grain-filling stage). Based on this, the development of uniform irrigation equipment for cold-resistant wheat cultivation can further optimize water distribution and help improve the planting efficiency of cold-resistant wheat.

[0003] Existing technologies have specifically developed uniform irrigation equipment for cold-resistant wheat cultivation. For example, Chinese patent publication number "CN219373323U" discloses "a uniform irrigation device for wheat cultivation." Rotation can also increase the distance of water jetting. During installation, the connecting part at the lower end of the machine head is placed on the mounting plate and precisely positioned using the slot and protruding rod. The connecting pipe and hose at the lower end are then fixed. Disassembly and installation are convenient. The water pipe is buried underground, and the equipment is easy to disassemble, facilitating later removal for wheat harvesting, saving time and labor.

[0004] Although rotation can increase the distance of water jetting, and during installation, the connecting part at the lower end of the machine head is placed on the mounting plate and precisely positioned using the slots and protruding rods, and the connecting pipe and hose at the lower end are fixed, making disassembly and installation convenient, this wheat cultivation uniform irrigation equipment has obvious shortcomings. The overall structure does not have a lifting component, and the height of the machine head and high-pressure nozzle is fixed, making it impossible to adjust the irrigation height according to the height of wheat at different growth stages. This easily leads to over-irrigation of short seedlings and under-irrigation of tall seedlings. Furthermore, it cannot adapt to areas with undulating terrain, limiting the irrigation range and requiring manual repositioning, increasing operating costs and affecting irrigation efficiency and uniformity.

[0023] Example

[0024] refer to Figures 1-4This embodiment of a uniform irrigation device for cold-resistant wheat cultivation includes a base plate 6. A fixed seat 7 is fixedly installed at the center of the upper end of the base plate 6. A drive motor 17 is fixedly installed on one side of the fixed seat 7. A rotating plate 5 is rotatably installed on the upper end of the fixed seat 7. A drive gear 18 is fixedly installed on the output shaft of the drive motor 17. A driven gear 19 is fixedly installed at the bottom of the rotating plate 5. The drive gear 18 and the driven gear 19 mesh with each other. Electric telescopic rods 3 are fixedly installed on both sides of the upper end of the rotating plate 5. A rotating head 1 is fixedly installed on the output shaft of the electric telescopic rod 3. A limiting component 4 is provided between the rotating plate 5 and the rotating head 1. Multiple nozzle components 2 are provided on the outer ring of the rotating head 1. A through-hole 23 is opened at the center of the bottom of the fixed seat 7. A conveying hose 8 is slidably installed inside the through-hole 23. The upper end of the conveying hose 8 rotates inside the rotating plate 5 and the rotating head 1. The other end of the conveying hose 8 is connected to a liquid supply device.

[0025] refer to Figures 1 to 4 The nozzle assembly 2 includes a fixing block 21 and a spray head 22. Multiple fixing blocks 21 are fixedly installed on the outer ring of the rotating head 1. A spray head 22 is fixedly installed on the end of the fixing block 21 away from the outer ring of the rotating head 1. The spray heads 22 are distributed in a ring around the rotating head 1, and the rotation speed can be controlled by adjusting the speed of the drive motor 17. Combined with the position of the spray head after height adjustment, the irrigation liquid can be evenly covered in the planting area to avoid local drought or waterlogging.

[0026] refer to Figure 2 The limiting component 4 includes limiting rods 9 and limiting grooves 10. The rotating head 1 has multiple limiting grooves 10 inside. Multiple limiting rods 9 are fixedly installed around the upper end of the rotating plate 5. The limiting rods 9 slide inside the rotating head 1 through the limiting grooves 10. The limiting rods 9 around the upper end of the rotating plate 5 always slide through the limiting grooves 10 inside the rotating head 1. The cooperation between the limiting rods 9 and the limiting grooves 10 can limit the rotational freedom of the rotating head 1, prevent the rotating head 1 from shifting or tilting when adjusting its height, and ensure that the rotating head 1 always remains horizontal, providing a stable base for the nozzle installation for subsequent uniform irrigation.

[0027] refer to Figures 4 to 5The rotating head 1 has a liquid storage chamber 20 inside, and a first rotating port 25 is opened at the center of the bottom of the liquid storage chamber 20. The delivery hose 8 extends into the liquid storage chamber 20 through the first rotating port 25. The liquid storage chamber 20 is connected to the nozzle assembly 2. The fixed base 7 has a fixed groove 27 inside, and a mounting platform 16 is fixedly installed on one side of the inner ring of the fixed groove 27. The drive motor 17 is fixedly installed on the upper end of the mounting platform 16. The drive motor 17 is fixedly installed inside the fixed base 7 through the mounting platform 16. A second rotating port 24 is opened at the center of the rotating plate 5 and the driven gear 19. The first rotating port 25 and the second rotating port 24 are connected to each other. A bearing 26 is fixedly installed inside the port 24. The delivery hose 8 rotates inside the first rotating port 25 and the second rotating port 24 through the bearing 26. When the external liquid supply equipment is started, the irrigation liquid is delivered to the liquid storage tank 20 inside the rotating head 1 through the delivery hose 8. The upper end of the delivery hose 8 extends into the liquid storage tank 20 through the first rotating port 25 and the second rotating port 24. The bearing 26 is fixed inside both the first rotating port 25 and the second rotating port 24. The bearing 26 can reduce the friction between the delivery hose 8 and the rotating head 1 and the rotating plate 5, and ensure that the delivery hose 8 will not be tangled or damaged when the rotating head 1 rotates with the rotating plate 5.

[0028] refer to Figures 2 to 3 The upper end of the fixed base 7 has a rolling groove 12. Multiple mounting seats 14 are fixedly installed around the bottom of the rotating plate 5. The mounting seats 14 have a rotating groove 15 inside. Rotating shafts 11 are fixedly installed on both sides inside the rotating grooves 15. Rolling wheels 13 are rotatably installed between the rotating shafts 11. The rolling wheels 13 slide inside the rolling grooves 12. The cooperation between the rolling wheels 13 and the rolling grooves 12 further distributes the weight of the rotating plate 5, reduces the pressure of the rotating plate 5 on the driven gear 19, and extends the service life of the gear transmission components. The delivery hose 8 is made of flexible material and can be flexibly deformed with the rotation and height adjustment of the rotating head 1. It is rotatably connected to the rotating head 1 and the rotating plate 5 through the bearing 26, which not only ensures the continuous delivery of irrigation liquid but also avoids hose wear.

[0029] Operating principle and advantages: Before using the equipment, basic installation and fluid connection must be completed: Place the base plate 6 at the preset irrigation point in the cold-resistant wheat planting field, ensuring that the base plate 6 is in stable contact with the ground; connect the end of the delivery hose 8 away from the rotating head 1 to the external liquid supply equipment. The liquid supply equipment can pre-mix irrigation liquid containing trace elements or antifreeze according to the water requirements of the cold-resistant wheat. At this time, the delivery hose 8 extends into the equipment through the through-hole 23 at the bottom of the fixed seat 7, laying the foundation for subsequent irrigation liquid delivery; at the same time, check the status of each component to ensure that the drive motor 17 and the electric telescopic rod 3 are powered normally, and the rolling wheel 1 is functioning properly. The coordination between the electric telescopic rod 3 and the rolling groove 12, and between the limiting rod 9 and the limiting groove 10, is smooth, ensuring that the equipment can start normally. The plant height of cold-resistant wheat varies greatly at different growth stages. It is necessary to adjust the irrigation height by coordinating the electric telescopic rod 3 with the limiting component 4 to ensure that the distance between the water spray head 22 and the wheat canopy is appropriate. When the electric telescopic rod 3 on both sides of the upper end of the rotating plate 5 is activated, the output shaft of the electric telescopic rod 3 extends and retracts, which drives the rotating head 1 fixed with it to move in the vertical direction. When the cold-resistant wheat is in the seedling stage, the electric telescopic rod 3 retracts, reducing the height of the rotating head 1 to prevent the irrigation liquid from splashing mud and contaminating the seedling leaves due to excessive falling distance.When the wheat enters the jointing stage, the electric telescopic rod 3 extends, raising the height of the rotating head 1 to ensure that the irrigation liquid can cover the entire wheat plant without causing excessive local irrigation due to insufficient distance. During this process, the limiting rods 9 around the upper end of the rotating plate 5 always slide through the limiting grooves 10 inside the rotating head 1. The cooperation between the limiting rods 9 and the limiting grooves 10 restricts the rotational freedom of the rotating head 1, preventing the rotating head 1 from shifting or tilting during height adjustment, ensuring that the rotating head 1 always remains horizontal, providing a stable base for the sprinkler installation for subsequent uniform irrigation. The drive motor 17 inside the fixed base 7 is started, and the output shaft of the drive motor 17 drives the drive gear 18 to rotate. Since the drive gear 18 and the driven gear 19 at the bottom of the rotating plate 5 are connected... When meshed, the rotational power of the driving gear 18 is transmitted to the driven gear 19, which in turn drives the rotating plate 5 to rotate around the upper end of the fixed base 7. When the rotating plate 5 rotates, the rolling wheels 13 in the mounting base 14 around its bottom slide synchronously in the rolling groove 12 at the upper end of the fixed base 7, which reduces the frictional resistance between the rotating plate 5 and the fixed base 7 and provides circumferential support for the rotating plate 5, preventing the rotating plate 5 from shaking due to unilateral force. When the external liquid supply equipment is started, the irrigation liquid is delivered to the liquid storage tank 20 inside the rotating head 1 through the delivery hose 8. The upper end of the delivery hose 8 extends into the liquid storage tank 20 through the first rotating port 25 and the second rotating port 24. Bearings 26 are fixed inside the first rotating port 25 and the second rotating port 24. The bearings 26 can reduce the frictional resistance between the rotating plate 5 and the fixed base 7, and thus reduce the frictional resistance between the rotating plate 5 and the fixed base 7. The friction between the delivery hose 8 and the rotating head 1 and rotating plate 5 is minimized to ensure that the delivery hose 8 will not become tangled or damaged when the rotating head 1 rotates with the rotating plate 5. The irrigation liquid in the storage tank 20 is distributed to multiple nozzle assemblies 2 on the outer ring of the rotating head 1 through internal channels, and finally evenly sprayed by the water nozzles 22 onto the surrounding cold-resistant wheat planting area. The continuous rotation of the rotating plate 5 drives the rotating head 1 and the water nozzles 22 to perform circular motion. The water nozzles 22 are distributed in a ring around the rotating head 1, and the rotation speed can be controlled by adjusting the speed of the drive motor 17. Combined with the height adjustment of the nozzle position, the irrigation liquid can be evenly covered in the planting area, avoiding local drought or waterlogging. The base plate 6 provides support for the entire equipment. The fixed base 7 and the fixed connection between the base plate 6 provide bottom support and ensure the overall stability of the equipment's center of gravity, preventing the equipment from tipping over due to centrifugal force during rotational irrigation. The cooperation between the rolling wheel 13 and the rolling groove 12 further distributes the weight of the rotating plate 5, reducing the pressure of the rotating plate 5 on the driven gear 19 and extending the service life of the gear transmission components. The delivery hose 8 is made of flexible material, which can flexibly deform with the rotation of the rotating head 1 and the height adjustment. It is rotatably connected to the rotating head 1 and the rotating plate 5 through the bearing 26, ensuring continuous delivery of irrigation liquid while preventing hose wear. The design of the liquid storage tank 20 can temporarily store irrigation liquid, balance the liquid outlet pressure of each spray head 22, ensure that the liquid outlet volume of each spray head 22 is consistent, and further improve irrigation uniformity.
