Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and in particular to an irrigation device for kiwifruit cultivation. Background Technology

[0002] Kiwifruit is a sun-loving tree species, tolerating partial shade and preferring cool, moist environments. It is susceptible to drought, waterlogging, and wind damage. While cold-hardy, it is intolerant of early spring frosts. It thrives in areas with mild climates, ample sunshine, abundant rainfall, relatively even precipitation during the growing season, and high air humidity (70%-80%). Areas with minimal early morning / late evening frost and freezing damage are also suitable. The ideal soil is deep, fertile, well-aerated, with a water table below 1 meter, high organic matter content, and a slightly acidic pH of 5.5-6.5. Strongly acidic or alkaline soils require improvement before cultivation. Various irrigation methods exist for kiwifruit, including flood irrigation, furrow irrigation, seepage irrigation, drip irrigation, and sprinkler irrigation. Flood irrigation is simple, easy to implement, and requires little investment, but it erodes the soil and can lead to soil compaction. Because flood irrigation is difficult to control and consumes a large amount of water, it is not conducive to the effective use of limited water resources and should be used sparingly.

[0003] Chinese invention patent CN107278810B discloses an irrigation device for kiwifruit cultivation, including a water-retaining planting cylinder, a main irrigation pipe, a drainage ditch, and an irrigation water temperature control system. The water-retaining planting cylinder is formed by covering the planting soil with water-retaining soil, which is made of a mixture of polyacrylamide hydrogel powder and soil powder. The water temperature in the main irrigation pipe is controlled by an irrigation water temperature control system consisting of a temperature-controlled water tank and a serpentine heat exchanger. The serpentine heat exchanger is equipped with a heating water tank and a refrigerant tank. The temperature-controlled water tank is equipped with a PLC controller, which includes high-temperature and low-temperature modes. This invention effectively solves the water retention problem of drip irrigation technology, possessing strong and controllable water retention capacity, achieving a slow-release water supply effect, preventing root rot and soil compaction caused by over-irrigation, and simultaneously enabling variable-temperature irrigation of the orchard, effectively preventing frost damage and heat damage, thus promoting kiwifruit growth. It has a wide range of applications and is suitable for widespread promotion.

[0004] However, the aforementioned equipment is not conducive to controlling the pressure of the sprayed water flow during use. Since the water pressure for agricultural irrigation is relatively unstable, when the water pressure is high, the water flow pressure from the nozzle is high and the jet speed is fast, which can damage the branches and leaves of kiwifruit and is not conducive to its growth.

[0005] Therefore, it is necessary to provide an irrigation device for kiwifruit cultivation to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an irrigation device for kiwifruit cultivation, in order to solve the problem mentioned in the background art that the existing equipment is not conducive to controlling the pressure of the sprayed water flow during use. Because the water pressure of agricultural irrigation is relatively unstable, when the water pressure is high, the water flow pressure from the nozzle is high and the jet speed is fast, which will damage the branches and leaves of kiwifruit and is not conducive to its growth.

The air inlet end of the second airbag is connected to the second flow channel on the limiting rod.

[0012] As a further embodiment of the present invention: a filter element is further provided inside the connecting pipe. The filter element is corrugated and has a top plate at the top and a bottom plate at the bottom. The top plate has a through hole opposite to the filter element. The bottom plate is a solid plate at the bottom end of the filter element. An annular groove is formed on the bottom plate on the outer side of the filter element, and a second filter plate is provided at the annular groove.

[0013] As a further aspect of the present invention: the filter element is provided with a shrinking assembly for compressing and adjusting the filter element. The upper half of the filter element is compressed by the shrinking assembly, while the lower half of the filter element is in an extended state.

[0014] As a further aspect of the present invention: the shrinkage assembly includes a partition assembly disposed on the outside of the vertical shaft. The partition assembly includes a fixed frame, a first filter plate, and an annular plate. The number of the annular plate and the first filter plate are each provided in two, and the annular plate and the first filter plate are spaced apart. The vertical shaft passes through the fixed frame and is slidably connected to it. The outermost annular plate is disposed inside the connecting pipe and is threadedly connected to the connecting pipe. The annular plate located between the two first filter plates passes through the filter element and is fixedly connected to it.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: When the volume of the second airbag increases, it can squeeze the bottom end of the adjusting rod, thereby causing the adjusting rod to deflect. At this time, the adjusting rod can drive the nozzle to rotate, thereby adjusting its angle, which is beneficial to adjusting the parabolic trajectory of the water flow. The adjusting component inside the connecting pipe can drive the nozzle to rotate counterclockwise, thereby increasing the arc of the sprayed water flow, so that it can directly pass over the adjacent kiwi trees and irrigate the next row of kiwi trees. When the water pressure inside the connecting pipe is normal, the water flow sprayed by the nozzle can directly irrigate the adjacent row of kiwi trees. Therefore, this structure can protect the kiwi trees and prevent damage to the kiwi trees from large water flow pressure. Attached Figure Description

[0033] like Figure 1-3 As shown, a kiwifruit planting irrigation device includes a connecting pipe 11 connected to an external pipeline. The top of the connecting pipe 11 is connected to a nozzle 1 via a flexible hose 9. Connecting plates 30 are provided on both the front and rear sides of the nozzle 1. The connecting plates 30 are fixedly connected to the connecting pipe 11, and the nozzle 1 is rotatably connected to the connecting plates 30 via pins arranged on its front and rear sides. At the same time, a protrusion 34 is fixedly connected to the inner side of the connecting plate 30. The protrusion 34 is provided at the bottom of the nozzle 1 to support it. The protrusion 34 enables the nozzle 1 to rotate only counterclockwise, while restricting its clockwise rotation.

[0034] Furthermore, the connecting pipe 11 is equipped with an adjustment component. When the water pressure inside the connecting pipe 11 is high, it can drive the nozzle 1 at its top to rotate counterclockwise upwards, thereby making the water sprayed from the nozzle 1 have a higher parabolic trajectory; the specific situation is as follows. Figure 9 As shown, in agricultural irrigation, water pressure is generally unstable, causing fluctuations in the water pressure inside the connecting pipe 11. When the water pressure inside the connecting pipe 11 increases, it directly leads to an increase in the water pressure inside the sprinkler head 1, resulting in increased spray pressure. If the angle of the sprinkler head 1 is not adjusted, the increased pressure water will hit the kiwi fruit's buds or leaves, causing damage. This device avoids this problem by adjusting the angle of the sprinkler head 1. In practical use, when the water pressure inside the connecting pipe 11 increases... When the water pressure is normal, the nozzle 1 can rotate counterclockwise through the adjustment component inside the connecting pipe 11. At this time, the nozzle 1 is in state a, which increases the arc of the sprayed water so that it can directly pass over the adjacent kiwi tree and irrigate the next row of kiwi trees. When the water pressure inside the connecting pipe 11 is normal, the nozzle 1 is in state b. At this time, the water sprayed by the nozzle 1 can directly irrigate the adjacent row of kiwi trees. Therefore, this structure can protect the kiwi trees and prevent damage to the kiwi trees from large water pressure.

[0035] like Figure 1 , 3 As shown in Figure 9, the adjustment assembly includes a vertical shaft 4 disposed inside the connecting pipe 11. A spiral blade 3 is fixedly connected to the bottom outer side of the vertical shaft 4. When water flows through the spiral blade 3, it can drive the blade to rotate, thereby driving the vertical shaft 4 to rotate. A turntable 18 is fixedly connected to the top outer side of the vertical shaft 4. The turntable 18 is hollow inside, and an annular first airbag 19 is disposed on the inner wall of this cavity. A driving ball 27 is also disposed inside the cavity of the turntable 18. A second spring 28 is fixedly connected between the driving ball 27 and the vertical shaft 4. The second spring 28 is disposed inside the cavity of the turntable 18. An exhaust pipe 20 is disposed on the outside of the first airbag 19, and the exhaust pipe 20 passes through the turntable 18.

[0036] Furthermore, an annular cavity 21 is formed on the inner wall of the connecting pipe 11, and the turntable 18 is rotatably connected to this annular cavity 21. The outer edge of the turntable 18 is located inside the annular cavity 21, and a limit rod 24 is fixedly connected to the outside of the connecting pipe 11. Figure 8 As shown, the limiting rod 24 is provided with a second flow channel 31, and the connecting pipe 11 is provided with a first flow channel 17 located at the annular cavity 21. The first flow channel 17 is connected to the annular cavity 21. At the same time, the end of the first flow channel 17 away from the annular cavity 21 is connected to the second flow channel 31. The exhaust pipe 20 connected to the first airbag 19 is connected to the annular cavity 21, so that the gas inside the first airbag 19 can be discharged into the annular cavity 21 through the exhaust pipe 20.

[0037] Furthermore, an adjusting rod 2 is connected to the outside of the nozzle 1. The bottom end of the adjusting rod 2 extends into the interior of the limiting rod 24. A second airbag 23 is fixedly installed on the side wall of the limiting rod 24 near the adjusting rod 2. The air inlet of the second airbag 23 is connected to the second guide channel 31 on the limiting rod 24, so that when the second airbag 23 expands, it can drive the adjusting rod 2 to deflect, thereby driving the nozzle 1 to rotate upward to adjust its angle. A first spring 22 is fixedly installed between the outside of the connecting pipe 11 and the adjusting rod 2 to drive the adjusting rod 2 to reset.

[0038] In practical use, when water from the external water pipe flows into the connecting pipe 11, it can drive the spiral blade 3 to rotate, thereby driving the vertical shaft 4 to rotate. The vertical shaft 4 can drive the turntable 18 at its top to rotate. The centrifugal force generated when the turntable 18 rotates causes the driving ball 27 to move outward against the force of the second spring 28, thereby squeezing the annular first airbag 19. The gas inside the first airbag 19 can be squeezed into the annular cavity 21 on the connecting pipe 11 through the exhaust pipe 20. Then, through the cooperation of the first guide channel 17 and the second guide channel 31, the gas inside the annular cavity 21 is squeezed into the second airbag 23. At this time, the volume of the second airbag 23 increases, which can squeeze the bottom end of the adjusting rod 2, thereby causing the adjusting rod 2 to deflect. At this time, the adjusting rod 2 can drive the nozzle 1 to rotate, thereby adjusting its angle, which is beneficial for adjusting the parabolic trajectory of the water flow.

[0039] like Figure 1 , 10 As shown in Figure 11, a filter element 5 is also installed inside the connecting pipe 11 to filter the water source. In agricultural irrigation, there are many impurities in the water. If it is not filtered, it will affect the use of the nozzle 1, thereby shortening the service life of the nozzle 1. The filter element 5 can provide good protection for the nozzle 1.

[0040] Furthermore, the filter element 5 is designed as a corrugated tube with a top plate 7 at its top and a bottom plate 32 at its bottom. The top plate 7 has a through hole that is opposite to the filter element 5, allowing water inside the filter element 5 to be discharged through the through hole. The bottom plate 32 is a solid plate at the bottom of the filter element 5 to prevent water from entering the filter element 5 directly from the bottom. An annular groove is provided on the outer side of the bottom plate 32, and a second filter plate 33 is provided at the annular groove.

[0041] In actual use, irrigation water can pass through the second filter plate 33 on the base plate 32 and flow to the outside of the filter element 5. After being filtered by the filter element 5, it enters the interior of the filter element 5 and is finally discharged through the top of the filter element 5. Therefore, during the water flow, the filter element 5 can filter the water thoroughly and completely, thereby protecting the nozzle 1.

[0042] A shrinkage assembly is installed inside the filter element 5 to adjust its compression and expansion. Initially, the upper part of the filter element 5 is compressed by the shrinkage assembly, while the lower part is correspondingly expanded. At this time, as... Figure 10As shown, after the water flows through the second filter plate 33 on the bottom plate 32, it flows upward to the space between the bottom plate 32 and the shrinkage assembly. After being filtered by the lower half of the extended filter element 5, it enters the interior of the filter element 5 and then passes through the top plate 7 before being discharged. Since the upper half of the filter element 5 is in a compressed state, it is compressed between the top plate 7 and the shrinkage assembly. Therefore, the water does not pass through the upper half of the filter element 5, thus making the upper half of the filter element 5 non-working and convenient for later use.

[0043] like Figure 11 As shown, after the lower half of the filter element 5 has been used for a period of time, the lower half of the filter element 5 can be compressed by the shrinking component, thereby extending the upper half of the filter element 5. At this time, the water flow can flow through the bottom plate 32 and the shrinking component to the bottom of the top plate 7, and be filtered by the upper half of the filter element 5. The filtered water can be discharged through the top of the filter element 5. Therefore, this device, by setting the shrinking component to cooperate with the filter element 5, can make reasonable use of the upper and lower parts of the filter element 5, thereby extending its service life and reducing its replacement cycle.

[0044] The shrinkage assembly includes a partition assembly 6 disposed outside the vertical axis 4, such as Figure 7 As shown, the partition assembly 6 includes a fixed frame 13, a first filter plate 12, and an annular plate 10. There are two annular plates 10 and two first filter plates 12, and the annular plates 10 and the first filter plates 12 are spaced apart. The first filter plate 12, the annular plate 10, and the fixed frame 13 are fixedly connected. The vertical shaft 4 passes through the fixed frame 13 and is slidably connected to it. The outermost annular plate 10 is located inside the connecting pipe 11 and is threadedly connected to the connecting pipe 11. The annular plate 10 located between the two first filter plates 12 passes through the filter element 5 and is fixedly connected to it, thereby dividing the filter element 5 into upper and lower parts. The vertical shaft 4 is a hollow columnar body, and a limiting groove 14 is provided on its outer wall inside the fixed frame 13. A limiting block 15 is slidably connected to the limiting groove 14.

[0045] Specifically, in order to improve the stability of the movement of the limiting block 15, a locking strip is provided on both the front and rear sides of the limiting block 15, and a locking groove is provided on both the front and rear side walls of the limiting groove 14 to cooperate with the locking strip. The cooperation between the locking strip and the locking groove enables the limiting block 15 to slide stably with the limiting groove 14.

[0046] A positioning block 16 is fixedly connected to the top of the inside of the fixed frame 13. The positioning block 16 is located on the top of the limiting block 15. When the limiting block 15 moves upward, it can cooperate with the positioning block 16, thereby driving the fixed frame 13 to rotate through the cooperation of the two, and then driving the outer ring plate 10 to rotate through the fixed block.

[0047] A horizontal shaft 29 is provided at the top of the vertical shaft 4, and a driving bevel gear 25 is fixedly connected to one end of the horizontal shaft 29 near the vertical shaft 4. A driven bevel gear 26 that meshes with the driving bevel gear 25 is fixedly connected to the top of the vertical shaft 4. A sleeve that supports the horizontal shaft 29 is fixedly connected to the inner wall of the connecting tube 11, and the horizontal shaft 29 passes through the sleeve and extends to the outside of the connecting tube 11. The horizontal shaft 29 is rotatably connected to the sleeve and the connecting tube 11. A pull rope 8 is provided inside the vertical shaft 4. The bottom end of the pull rope 8 is fixedly connected to the limiting block 15. The top end of the pull rope 8 extends to the outside of the vertical shaft 4 and passes through the horizontal shaft 29. A pulley is provided at the corner of the pull rope 8. The pulley is fixedly connected to the connecting tube 11, and the pull rope 8 is movably connected to the horizontal shaft 29, so that the pull rope 8 can move inside the horizontal shaft 29. A pull ring is fixedly connected to one end of the pull rope 8 extending to the outside of the horizontal shaft 29, and a lever is fixedly connected to one end of the horizontal shaft 29 extending to the outside of the connecting tube 11.

[0048] In actual use, when adjusting the filter element 5 by gradually adjusting the baffle, the pull rope 8 can be pulled by the pull ring. The pull rope 8 drives the limiting block 15 to move upward. When the limiting block 15 moves to the side of the positioning block 16, the horizontal shaft 29 is rotated by the lever. The meshing of the driving bevel gear 25 and the driven bevel gear 26 drives the vertical shaft 4 to rotate. The cooperation between the limiting block 15 and the positioning block 16 allows the vertical shaft 4 to drive the fixed frame 13 to rotate. The fixed frame 13 can drive the outer annular plate 10 to rotate. The annular plate 10 is threadedly connected to the inner wall of the connecting pipe 11. Therefore, when the vertical shaft 4 drives the annular plate 10 to rotate, it can move it up and down. The annular plate 10 divides the filter element 5 into upper and lower parts. Therefore, when the annular plate 10 moves with the fixed frame 13, it can... The upper or lower half of the filter element 5 can be compressed. For example, when the annular plate 10 is moved downward by the vertical shaft 4, the lower half of the used filter element 5 can be compressed, while the upper half of the filter element 5 will extend. At this time, the water flow will enter the bottom of the annular plate 10 through the second filter plate 33 on the bottom plate 32, and then flow upward to the bottom of the top plate 7 through the first filter plate 12 between the two annular plates 10. After that, it will be filtered through the upper half of the filter element 5 and enter the interior of the filter element 5, and finally be discharged through the top of the filter element 5, thus completing the filtration of the water flow. In normal use, since the limiting block 15 and the positioning block 16 are offset from each other, the rotation of the vertical shaft 4 will not drive the fixed frame 13 and the annular plate 10 to rotate, so that the filter element 5 can be used normally.

[0049] In summary, this device can adjust the parabolic trajectory of the water flow by adjusting the angle of the nozzle 1, thereby protecting the kiwifruit tree. Furthermore, by configuring the filter element 5 to cooperate with the shrinkage assembly, its service life and replacement cycle can be extended, making it highly practical.

[0050] like Figure 12As shown, for another adjustment method of the adjusting rod 2, a motor 35 can be installed on the limiting rod 24. A cam 36 is connected to the output shaft of the motor 35. The cam 36 is located on one side of the adjusting rod 2. When in use, the motor 35 drives the cam 36 to rotate. The cam 36 squeezes the adjusting rod 2, and together with the first spring 22, the adjusting rod 2 can be adjusted.
