Description

Technical Field

[0001] This utility model relates to a drip irrigation device for soil and vegetation restoration in arid areas, belonging to the field of drip irrigation technology. Background Technology

[0002] In soil and vegetation restoration work in arid regions, drip irrigation technology is a crucial means to ensure vegetation survival and growth. Traditional drip irrigation systems often struggle to achieve a uniform and stable water flow distribution. After water enters the branch pipes from the main pipe, its distribution to the drip heads is often limited by the design of the drip heads, making it impossible to guarantee that water will drip into the soil in a uniform and slow manner. This can lead to some areas being over-watered and others under-watered, affecting vegetation's water absorption and hindering soil and vegetation restoration. Furthermore, existing drip irrigation systems lack effective adjustment capabilities for the drip water flow rate. Since different vegetation types have varying water requirements at different growth stages, and the water retention capacity of soils in different areas of arid regions differs, a device capable of flexibly adjusting the drip water flow rate is needed. However, once installed, traditional drip irrigation systems have a essentially fixed flow rate that cannot be adjusted according to actual conditions, making it difficult to meet the diverse drip irrigation needs during soil and vegetation restoration in arid regions. Therefore, a new drip irrigation device for soil and vegetation restoration in arid regions is proposed. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a drip irrigation device for soil and vegetation restoration in arid areas, which provides the necessary water for vegetation and helps the soil and vegetation to recover.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a drip irrigation device for soil and vegetation restoration in arid areas, comprising:

[0005] General Manager;

[0006] Multiple branch pipes are evenly distributed on the main pipe;

[0007] The drip head is connected to the end of the branch pipe that is furthest from the main pipe.

[0008] The drip irrigation head includes:

[0009] The nozzle is connected to the branch pipe, and multiple water outlet holes are evenly distributed on the nozzle.

[0010] The outer casing is fitted onto the nozzle, and multiple water outlet holes are evenly distributed on the outer casing.

[0011] A sponge layer is placed between the nozzle and the outer casing.

[0012] Preferably, the outer wall of the nozzle is provided with an external thread, and the rear end of the housing is provided with an internal thread, wherein the internal thread engages with the external thread;

[0013] When the outer casing is rotated, the internal thread rotates on the external thread, causing the outer casing to slide along the axis of the nozzle.

[0014] Preferably, the nozzle front end is provided with a cone one, the outer shell front end is provided with a cone two that matches the shape of the cone one, and the water outlet holes two are evenly distributed on the cone two;

[0015] As the outer shell slides along the axis of the nozzle, the second cone and the sponge layer of the cone are compressed to different degrees.

[0016] Preferably, the nozzle is connected to the end of the branch pipe by a thread.

[0017] Preferably, the sponge layer is fixedly sleeved onto the outer wall of the nozzle.

[0018] Preferably, one end of the main pipe is provided with a connecting component, the connecting component comprising:

[0019] A connector that is inserted into the end of the main pipe;

[0020] A threaded cap, which is fixed to the connector head, is used to connect to an external water pump outlet pipe;

[0021] A ring clamp is fitted onto the outer wall of the end of the main pipe to clamp the main pipe onto the connector.

[0022] Preferably, an annular groove is formed on the outer wall of the connector, and the annular clamp clamps the main pipe within the annular groove.

[0023] Preferably, the outer wall of the wire cap has a plurality of planes arranged circumferentially for engaging with an external hexagonal wrench.

[0024] Preferably, a cap is provided at the other end of the main pipe.

[0025] Preferably, the main pipe and the branch pipes are connected by quick-connect water pipe couplings.

[0026] Compared with existing technologies:

[0027] 1. This utility model distributes water through a main pipe to various branch pipes. The end of each branch pipe furthest from the main pipe is connected to a drip irrigation head, from which water further flows into the nozzles. Multiple evenly distributed water outlet holes (number 1 and number 2) on the nozzle and its outer casing initially disperse the water. A sponge layer between the nozzle and the outer casing effectively blocks external impurities, preventing them from entering the branch pipes through the water outlet holes and causing blockages. In this way, water is dripped into the soil of arid areas in a relatively uniform and slow manner, providing the necessary moisture for vegetation and aiding in soil and vegetation recovery.

[0028] 2. This utility model achieves this by having the outer shell slide along the axis of the nozzle and the second cone slide close to the first cone. This increases the pressure between the second cone and the pair of sponge layers, thus increasing the restriction on the outflow velocity of the water and reducing the outflow velocity. Conversely, when the outer shell slides along the axis of the nozzle and the second cone slides away from the first cone, the pressure between the second cone and the pair of sponge layers decreases, reducing the restriction on the outflow velocity and increasing the outflow velocity. This effectively regulates the water flow rate during drip irrigation. Attached Figure Description

[0043] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0044] Example 1

[0045] like Figures 1-6 As shown in this embodiment, a drip irrigation device for soil and vegetation restoration in arid areas is provided, including a main pipe 1; multiple branch pipes 2 are evenly distributed on the main pipe 1; a drip irrigation head 3 is connected to the end of each branch pipe 2 away from the main pipe 1; wherein, the drip irrigation head 3 includes a nozzle 31, the nozzle 31 is connected to the branch pipe 2, and multiple water outlet holes 32 are evenly distributed on the nozzle 31; a shell 33 is fitted onto the nozzle 31, and multiple water outlet holes 34 are evenly distributed on the shell 33; a sponge layer is provided between the nozzle 31 and the shell 33 to prevent external impurities from entering the interior of the branch pipe 2 through the water outlet holes 32 and 34, causing blockage inside the branch pipe 2. A cap 5 is provided at the other end of the main pipe 1. The main pipe 1 and the branch pipes 2 are connected by a quick-connect water pipe connector 6.

[0046] Work process:

[0047] When carrying out soil and vegetation restoration work in arid areas, the drip irrigation system is first installed. A main pipe 1 is connected to multiple branch pipes 2 via quick-connect fittings 6. One end of the main pipe 1 is connected to a water source, and the other end is sealed with a cap 5. When irrigation begins, water flows into the main pipe 1. Since multiple branch pipes 2 are evenly distributed on the main pipe 1, the water is distributed into each branch pipe 2 under pressure. The end of each branch pipe 2 furthest from the main pipe 1 is connected to a drip irrigation head 3, and the water further flows into the nozzle 31 of the drip irrigation head 3. Multiple outlet holes 32 and 34 evenly distributed on the nozzle 31 and its outer casing 33 initially disperse the water. A sponge layer 35 placed between the nozzle 31 and the outer casing 33 effectively blocks external impurities, preventing them from entering the branch pipes 2 through the outlet holes 32 and 34, thus avoiding blockages.

[0048] Guided by multiple water outlet holes 1 32 and multiple water outlet holes 2 34, water will drip into the soil in the arid area in a relatively uniform and slow manner, providing the vegetation with the necessary moisture and helping the soil and vegetation to recover.

[0049] Example 2

[0050] like Figures 2-5As shown, based on Embodiment 1, in this embodiment, the outer wall of the nozzle 31 is provided with an external thread 36, and the rear end of the outer shell 33 is provided with an internal thread 37. The internal thread 37 is engaged with the external thread 36, and the length of the external thread 36 is longer than the length of the internal thread 37.

[0051] When the housing 33 is rotated, the internal thread 37 rotates on the external thread 36, causing the housing 33 to slide along the axis of the nozzle 31.

[0052] The nozzle 31 has a cone 311 at the front end, and the outer shell 33 has a cone 331 at the front end that matches the shape of the cone 311. The water outlet holes 34 are evenly distributed on the cone 331.

[0053] When the outer shell 33 slides along the axis of the nozzle 31, the second cone 331 and the first cone 311 press the sponge layer 35 to different degrees. When the outer shell 33 slides along the axis of the nozzle 31 and the second cone 331 moves closer to the first cone 311, the pressing force of the second cone 331 and the first cone 311 on the sponge layer 35 increases, and the pressed sponge layer 35 increases the restriction on the outflow velocity of the water, thereby reducing the outflow velocity of the water. Conversely, when the outer shell 33 slides along the axis of the nozzle 31 and the second cone 331 moves away from the first cone 311, the pressing force of the second cone 331 and the first cone 311 on the sponge layer 35 decreases. At this time, the restriction on the outflow velocity of the water by the sponge layer 35 decreases, thereby increasing the outflow velocity of the water. In this way, the flow rate of the water during drip irrigation can be effectively adjusted.

[0054] The nozzle 31 is connected to the end of the branch pipe 2 by a thread, making the nozzle 31 detachable.

[0055] The sponge layer 35 is fixedly sleeved onto the outer wall of the nozzle 31.

[0056] During installation, the nozzle 31 is fixed on the branch pipe 2, and then the outer shell 33 is fitted onto the nozzle 31. At this time, the sponge layer 35 is between the nozzle 31 and the outer shell 33. Then, the outer shell 33 is rotated, and the internal thread 37 on the outer shell 33 engages with the external thread 36. The position of the internal thread 37 engaging with the external thread 36 is controlled according to the number of rotations, that is, the force of the first cone 311 and the second cone 331 pressing the sponge is controlled. When the force is adjusted, the installation of the drip irrigation head 3 is completed.

[0057] Example 3

[0058] like Figure 1 and Figure 6As shown, based on the above embodiments, in this embodiment, a connecting component 4 is provided at one end of the main pipe 1. The connecting component 4 includes a connector 41, which is inserted into the end of the main pipe 1. A threaded cap 42 for connecting to an external water pump outlet pipe is fixedly connected to the connector 41. A ring clamp 43 for clamping the main pipe 1 onto the outer wall of the end of the main pipe 1 is fitted on the connector 41.

[0059] An annular groove 44 is provided on the outer wall of the connector 41. The ring clamp 43 clamps the main pipe 1 in the annular groove 44. The connecting assembly 4 secures the main pipe 1 in the annular groove 44 of the connector 41 through the ring clamp 43 to ensure sealing.

[0060] The outer wall of the wire cap 42 has a plurality of planes 421 arranged in a circumferential array for engaging with an external hex wrench.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
