Description

Technical Field

[0001] This invention belongs to the field of agricultural irrigation technology, specifically a water-saving drip irrigation device for planting in saline-alkali land. Background Technology

[0002] Saline-alkali land is a type of land where the salt and alkali content in the soil is too high, leading to the deterioration of the soil's physical and chemical properties and affecting the normal growth of plants.

[0003] Because of the high salt content in saline-alkali soil, irrigation is necessary when planting crops on saline-alkali land. Irrigation water can not only dissolve the salt in the soil surface, but also carry the salt to the deeper soil layers through leaching, thereby reducing the salt concentration in the surface soil and creating a suitable saline environment for crop growth.

[0004] Moreover, crops need sufficient water to grow. Although saline-alkali land may contain some usable water, the crop roots have difficulty absorbing water due to the influence of salt. Irrigation can replenish soil moisture, meet the water needs of crop growth, and is beneficial to the growth and development of crop roots.

[0005] Traditionally, irrigation methods such as drip irrigation and sprinkler irrigation are used. These methods can control the amount of irrigation water. However, the water sprayed out mainly seeps down through the surface. When there is a lot of salt accumulation on the soil surface, the surface soil has poor permeability, which makes it difficult for water to seep down. This not only increases the amount of irrigation water and wastes water resources, but also makes it difficult for the roots to absorb deep water. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a water-saving drip irrigation device for planting in saline-alkali land, which solves the problem of water waste in traditional irrigation methods when encountering situations where there is a high concentration of salt on the soil surface.

[0007] A water-saving drip irrigation device for planting in saline-alkali land includes a hollow placement ring, a sealing plate fixedly connected to the bottom of the placement ring, a ring of placement holes distributed in a ring, a drip irrigation head placed in the placement holes, and a nested secondary pipe above the sealing plate and inside the placement ring.

[0008] It also includes a water storage chamber, which is located between the nested sub-pipe and the mounting ring. The nested sub-pipe is provided with a water outlet, and the outer wall of the mounting ring is provided with a movably connected protective shielding component.

[0009] The bottom of the nested sub-pipe is sealed. The bottom plate of the nested sub-pipe is provided with a fixedly connected magnetic chuck, and the top of the sealing plate is provided with a magnetic chuck. The magnetic chuck and the magnetic chuck attract each other. A connecting pipe is provided at the top of the nested sub-pipe. One end of the connecting pipe is connected to the nested sub-pipe by means of a thread, and the other end of the connecting pipe is connected to a water supply pipe.

[0010] The water outlet holes are arranged in a ring on the nested sub-pipe, and there are no less than two layers. A cleaning plate is provided on the outer wall of the nested sub-pipe at the bottom position. The cleaning plate is located in the water storage chamber. A rubber sealing ring is provided on the outer wall of the cleaning plate. The outer wall of the rubber sealing ring is in movable contact with the inner wall of the sealing plate.

[0011] The height of the nested sub-tube is greater than the height of the mounting ring. The outer wall of the nested sub-tube is provided with a fixedly connected warning plate. The outer wall of the warning plate is movably fitted with the inner wall of the mounting ring, and the top surface of the warning plate is flush with the top surface of the mounting ring. Symmetrically through warning openings are provided on the warning plate.

[0012] Preferably, the outer wall of the mounting ring is provided with multiple layers of evenly spaced scale lines, the mounting hole is provided with no less than two layers on the mounting ring, the outer wall of the drip head is equipped with a rubber ring, and the drip head is movably inserted into the mounting hole.

[0013] Preferably, the protective shielding assembly includes a limiting and receiving plate, a hidden chamber, and a protective plate. The limiting and receiving plate is fixedly connected to the top of the sealing disc and is distributed in a ring-shaped interval outside the placement ring. The top of the limiting and receiving plate is fixedly connected to the top of the placement ring. The hidden chamber is located between the inner wall of the limiting and receiving plate and the outer wall of the placement ring, and the hidden chamber is an arc-shaped chamber. The protective plate is located between two adjacent limiting and receiving plates, and the protective plate and the hidden chamber cooperate with each other. When the protective plate is located between two limiting and receiving plates, the protective plate shields the drip head. The protective plate is movably connected to the sealing disc.

[0014] Preferably, an annular groove is provided on the top of the sealing disc and outside the mounting ring, and mating balls are provided in the annular groove at intervals. The bottom of the protective plate is inserted into the annular groove and dynamically contacts the mating balls.

[0015] Preferably, a scraper is provided on one side of the protective plate extending into the side wall of the hidden cavity, and a positioning post is provided on the top of each protective plate and near the scraper. A rotating ring is provided above the protective plate, and the bottom of the rotating ring is fixedly connected to the top of the positioning post.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention utilizes a placement ring, which is placed in a pre-drilled hole. A sealing plate is located at the bottom of the placement ring. The placement ring has annular, multi-layered placement holes, into which drip irrigation heads are inserted. A nested secondary pipe is located inside the placement ring and has an outlet hole. When irrigation water enters the nested secondary pipe, it exits through the outlet hole and enters a water storage chamber. From there, it flows through the drip irrigation head into the soil. Because the drip irrigation head is pre-buried underground, the water can directly contact the roots or other parts of the plant. Compared to traditional methods where watering is limited to the surface and difficult to penetrate, this invention significantly saves water resources and improves irrigation efficiency for plants in saline-alkali land.

[0018] 2. This invention improves the uniformity of water flow by designing the water outlet in a ring shape on the nested secondary pipe. The water flow rate of the water outlet is designed to be greater than that of the drip irrigation head. When water enters the water storage chamber from the water outlet, although water will come out from the drip irrigation head, water will also accumulate in the water storage chamber. Thus, even when the water supply pipe stops supplying water, there will still be residual water in the water storage chamber, which can continue to irrigate the plants, thus improving the flexibility of irrigation.

[0019] 3. This invention features a protective shielding component. A limiting and receiving plate is fixedly connected between the sealing disc and the placement ring. A hidden chamber is set between the limiting and receiving plate and the placement ring. The protective plate and the hidden chamber cooperate with each other. When the protective plate is rotated into the hidden chamber, the drip irrigation head will be exposed, allowing water to flow from the drip irrigation head to irrigate the soil. When drip irrigation is no longer needed, the protective plate can be rotated to shield the drip irrigation head, thereby reducing soil adhesion to the drip irrigation head and preventing subsequent blockage.

[0020] 4. This invention designs the height of the nested secondary pipe to be greater than the height of the installation ring, thus allowing the nested secondary pipe to be easily pulled out of the installation ring. A warning disc is installed on the outside of the nested secondary pipe, located at the top of the water storage chamber. The warning disc has a warning hole. Since the flow rate of the water outlet is greater than the flow rate of the drip irrigation head, water will slowly accumulate in the water storage chamber. After accumulating to a certain height, the water will come out from the warning hole, thus reminding the irrigation personnel that the water storage chamber is full and thus stopping the water supply in time.

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] As attached Figure 1 To be continued Figure 7 As shown:

[0032] Example 1: The present invention provides a water-saving drip irrigation device for planting in saline-alkali land, including a hollow placement ring 1, a sealing plate 2 fixedly connected to the bottom of the placement ring 1, a ring-shaped distribution of placement holes 3 on the placement ring 1, a drip irrigation head 4 placed in the placement holes 3, and a nested secondary pipe 5 above the sealing plate 2 and inside the placement ring 1.

[0033] It also includes a water storage chamber 6, which is located between the nested secondary pipe 5 and the mounting ring 1. The nested secondary pipe 5 is provided with a water outlet 7, and the outer wall of the mounting ring 1 is provided with a movably connected protective shielding component.

[0034] It should be noted that the installation ring 1 is placed in a pre-drilled hole, and a sealing plate 2 is set at the bottom of the installation ring 1. The installation ring 1 has a ring-shaped and multi-layered installation hole 3, and a drip irrigation head 4 is inserted into the installation hole 3. The nested sub-pipe 5 is located inside the installation ring 1. The nested sub-pipe 5 has a water outlet hole 7. When the irrigation water enters the nested sub-pipe 5, it will come out from the water outlet hole 7 and enter the water storage chamber 6. Then, it will flow from the water storage chamber 6 through the drip irrigation head 4 into the soil. Since the drip irrigation head 4 is pre-buried underground, the water can directly contact the roots of the plant or other parts. Compared with the traditional method of watering the surface, which is difficult to penetrate downwards, this invention can greatly save water resources and improve the irrigation efficiency of plants in saline-alkali land.

[0035] In this embodiment, the outer wall of the mounting ring 1 is provided with multiple layers of uniformly spaced scale lines 8, the mounting hole 3 is provided with no less than two layers on the mounting ring 1, the outer wall of the drip head 4 is equipped with a rubber ring, and the drip head 4 is movably inserted into the mounting hole 3.

[0036] It should be noted that by designing scale lines 8 on the outer wall of the installation ring 1, the depth of the installation ring 1 buried underground can be known through the scale lines 8 after the installation ring 1 is pre-buried underground. Combined with the position of the drip irrigation head 4 on the installation ring 1, the height of the drip irrigation head 4 can be known. Thus, by pre-burying the installation ring 1 at different depths according to different plants, the drip irrigation head 4 can better achieve drip irrigation for the plants.

[0037] The number of installation holes 3 on the installation ring 1 is no less than two layers. After the installation ring 1 is pre-buried underground, drip irrigation can be achieved for soil at different depths, thereby improving the efficiency of drip irrigation. At the same time, a rubber ring is set on the outer wall of the drip head 4. The drip head 4 is inserted into the installation hole 3. If the drip head 4 is damaged in the future, it can be quickly removed from the installation hole 3 for easy replacement.

[0038] In this embodiment, the bottom of the nested sub-pipe 5 is sealed. The bottom of the base plate of the nested sub-pipe 5 is provided with a fixedly connected magnetic chuck 9, and the top of the sealing plate 2 is provided with a magnetic chuck 10. The magnetic chuck 9 and the magnetic chuck 10 attract each other. The top of the nested sub-pipe 5 is provided with a connecting pipe 11. One end of the connecting pipe 11 is connected to the nested sub-pipe 5 by means of a thread, and the other end of the connecting pipe 11 is connected to a water supply pipe 12.

[0039] It should be noted that by setting a magnetic chuck 9 at the bottom of the nested sub-tube 5 and a magnetic chuck 10 at the top of the sealing plate 2, the magnetic chuck 9 and magnetic chuck 10 attract each other, thus realizing the movable connection between the nested sub-tube 5 and the placement ring 1. In the event that there are many impurities inside the nested sub-tube 5 later, the nested sub-tube 5 can be quickly removed from the placement ring 1. Moreover, after the nested sub-tube 5 is placed into the placement ring 1, it can be held in place by magnetic attraction. After water is passed through the nested sub-tube 5, it is prevented from moving in the water storage chamber 6, thus ensuring the stability of the water output.

[0040] By setting a connecting pipe 11 at the top of the nested secondary pipe 5, the connecting pipe 11 is connected to the nested secondary pipe 5 by means of threads. On the one hand, the two can be detached, and on the other hand, the height of the connecting pipe 11 can be adjusted by rotating it on the nested secondary pipe 5, so as to better connect it with the water supply pipe 12. The water supply pipe 12 can connect multiple connecting pipes 11, so as to supply water to multiple irrigation devices.

[0041] In this embodiment, the water outlet 7 is arranged in a ring on the nested secondary pipe 5, and the number of layers is not less than two. The water flow rate of the water outlet 7 is greater than the water flow rate of the drip irrigation head 4. A cleaning plate 13 is provided on the outer wall of the nested secondary pipe 5 at the bottom position. The cleaning plate 13 is located in the water storage chamber 6. A rubber sealing ring 14 is provided on the outer wall of the cleaning plate 13. The outer wall of the rubber sealing ring 14 is in contact with the inner wall of the sealing plate 2.

[0042] It should be noted that by designing the water outlet 7 in a ring shape on the nested secondary pipe 5, the uniformity of water flow can be improved. The water flow rate of the water outlet 7 is designed to be greater than that of the drip irrigation head 4. When water enters the water storage chamber 6 from the water outlet 7, although water will come out from the drip irrigation head 4, water will also accumulate in the water storage chamber 6. Thus, when the water supply pipe 12 stops supplying water, there will still be residual water in the water storage chamber 6, which can continue to irrigate the plants, thus improving the flexibility of irrigation.

[0043] A cleaning disc 13 is fixedly connected to the bottom of the outer wall of the nested sub-pipe 5. The outer wall of the cleaning disc 13 has a rubber sealing ring 14, which ensures the sealing between the cleaning disc 13 and the placement ring 1, so that water will not leak to the bottom of the cleaning disc 13. Since the nested sub-pipe 5 is designed to be movable, when external impurities enter the water storage chamber 6 through the drip head 4, after drip irrigation is completed, the nested sub-pipe 5 can be pulled upwards to remove it for cleaning. At the same time, it will also drive the cleaning disc 13 to rise, thereby bringing out the impurities that have settled on the cleaning disc 13. This achieves the cleaning of impurities in the water storage chamber 6, which is convenient and quick.

[0044] In this embodiment, the protective shielding assembly includes a limiting and receiving plate 15, a hidden chamber 16, and a protective plate 17. The limiting and receiving plate 15 is fixedly connected to the top of the sealing disc 2 and is distributed in a ring-shaped interval outside the placement ring 1. The top of the limiting and receiving plate 15 is fixedly connected to the top of the placement ring 1. The hidden chamber 16 is located between the inner wall of the limiting and receiving plate 15 and the outer wall of the placement ring 1, and the hidden chamber 16 is an arc-shaped chamber. The protective plate 17 is located between two adjacent limiting and receiving plates 15, and the protective plate 17 and the hidden chamber 16 cooperate with each other. When the protective plate 17 is located between two limiting and receiving plates 15, the protective plate 17 shields the drip head 4. The protective plate 17 is movably connected to the sealing disc 2.

[0045] It should be noted that, through the protective shielding component, the limiting and receiving plate 15 is fixedly connected between the sealing plate 2 and the placement ring 1. A hidden chamber 16 is set between the limiting and receiving plate 15 and the placement ring 1. The protective plate 17 and the hidden chamber 16 cooperate with each other. When the protective plate 17 rotates into the hidden chamber 16, the drip irrigation head 4 will be exposed, so that water can come out from the drip irrigation head 4 to irrigate the soil. When drip irrigation is no longer needed, the protective plate 17 can be rotated to shield the drip irrigation head 4, thereby reducing the situation of soil adhering to the drip irrigation head 4 and causing the drip irrigation head 4 to become blocked later. At the same time, the limiting and receiving plate 15 can limit the stroke of the protective plate 17 and will not detach from the hidden chamber 16.

[0046] In this embodiment, an annular groove 18 is provided on the top of the sealing disc 2 and outside the mounting ring 1. Interval mating balls 19 are provided in the annular groove 18. The bottom of the protective plate 17 is inserted into the annular groove 18 and dynamically contacts the mating balls 19.

[0047] It should be noted that by setting an annular groove 18 on the top of the sealing disc 2, and placing spaced mating balls 19 in the annular groove 18, the mating balls 19 can roll in the annular groove 18, and the bottom of the protective plate 17 is in dynamic contact with the mating balls 19. When force is applied to the protective plate 17, the rotation of the protective plate 17 can be better achieved.

[0048] In this embodiment, a scraper 20 is provided on the side wall of the protective plate 17 extending into the hidden chamber 16. A positioning post 21 is provided on the top of each protective plate 17 and on the side near the scraper 20. A rotating ring 22 is provided above the protective plate 17, and the bottom of the rotating ring 22 is fixedly connected to the top of the positioning post 21.

[0049] It should be noted that by setting a scraper 20 on one side of the protective plate 17, when the protective plate 17 enters the hidden chamber 16 during irrigation, the scraper 20 is located outside the hidden chamber 16. After irrigation is completed, as the protective plate 17 comes out of the hidden chamber 16, the scraper 20 rotates with the protective plate 17 to scrape the outer wall of the placement ring 1, thereby scraping off the soil attached to the outer wall of the placement ring 1. At the same time, it can also scrape the head of the drip irrigation head 4, which not only cleans the outer wall of the placement ring 1, but also further cleans the drip irrigation head 4.

[0050] By setting a positioning post 21 at the top of the protective plate 17, and a rotating ring 22 at the top of the positioning post 21, when it is necessary to rotate the protective plate 17, a person can apply force to the rotating ring 22 to drive the entire protective plate 17 to rotate, thereby improving the ease of rotation of the protective plate 17.

[0051] In this embodiment, the height of the nested sub-tube 5 is greater than the height of the mounting ring 1. The outer wall of the nested sub-tube 5 is provided with a fixedly connected warning plate 23. The outer wall of the warning plate 23 is in movable contact with the inner wall of the mounting ring 1, and the top surface of the warning plate 23 is flush with the top surface of the mounting ring 1. The warning plate 23 is symmetrically provided with through warning openings 24.

[0052] It should be noted that by designing the height of the nested secondary pipe 5 to be greater than the height of the mounting ring 1, the nested secondary pipe 5 can be easily pulled out from the mounting ring 1. A warning disc 23 is set on the outside of the nested secondary pipe 5. The warning disc 23 is located at the top of the water storage chamber 6. A warning hole is opened on the warning disc 23. Since the flow rate of the water outlet 7 is greater than the flow rate of the drip irrigation head 4, the water will slowly accumulate in the water storage chamber 6. After accumulating to a certain height, the water will come out from the warning hole 24, thereby reminding the irrigation personnel that the water storage chamber 6 is full, so as to stop the water supply in time.

[0053] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
