Description

Technical Field

[0001] This utility model relates to the field of fruit tree irrigation technology, specifically a water-saving fruit tree root irrigation device. Background Technology

[0002] Many fruit trees in my country are planted in arid and semi-arid regions such as mountains and hills. These areas often have complex terrain, extremely scarce water resources, and limited irrigation facilities. Traditional fruit tree irrigation methods have very low utilization rates and are extremely unsuitable for water-scarce mountain environments.

[0003] To address these issues, water-saving irrigation technologies such as drip irrigation and subsurface irrigation have been applied. However, existing irrigation systems typically rely on extensive underground pipe networks, resulting in high initial construction costs and difficulties in maintenance and energy consumption, especially for the scattered fruit tree planting patterns in mountainous areas. Furthermore, these systems primarily depend on external water sources, failing to effectively collect and utilize natural rainwater resources. In mountainous areas with frequent rainfall but significant seasonal droughts, this leads to substantial water waste. Additionally, fruit tree roots are unevenly distributed in the soil, consisting of taproots, lateral roots, and numerous capillary roots that absorb nutrients. Existing irrigation devices mostly irrigate from a single direction or only at the soil surface, making it difficult to ensure that water reaches the core root system at different depths evenly and directly, resulting in uneven irrigation and some roots failing to effectively absorb water. Utility Model Content

[0004] To address the problem of rainwater harvesting being difficult to utilize in fruit tree irrigation, this invention provides a water-saving fruit tree root irrigation device.

[0005] The technical solution of this utility model is as follows: A water-saving fruit tree root irrigation device includes a ring-shaped support frame set around the trunk of a fruit tree and a support device that can support the ring-shaped support frame. A water storage tank is set on the ring-shaped support frame. The water storage tank surrounds the outside of the vertical projection of the fruit tree trunk. The end of the water storage tank near the ring-shaped support frame is connected to a water distribution channel through a water supply pipe. The side of the water distribution trough away from the water supply pipe extends toward the root area of ​​the fruit tree and is connected to multiple irrigation pipes. The end of the irrigation pipe facing the water distribution trough extends to the top of the water distribution trough, and multiple through holes are opened on the surface of the irrigation pipe located inside the water distribution trough. The water distribution channel is also equipped with a float, which is fitted on the outside of the irrigation pipe and can move freely up and down along the surface of the irrigation pipe.

[0006] Preferably, the floats fitted on the surface of the irrigation pipe are connected to each other as a single unit.

[0007] To prevent water from flowing directly through the irrigation pipe from the inside of the water supply pipe, the water supply pipe and the irrigation pipe are not coaxially arranged.

[0008] To facilitate control of water flow rate and prevent excessive water flow from affecting the root system, the float is designed with an arc-shaped structure on the side near the top of the water distribution channel, and a protrusion that can block the water supply pipe is provided at the position of the float directly below the water supply pipe.

[0009] To facilitate adjustment of irrigation pipes at different locations, the different irrigation pipes have the same outer diameter but different inner diameters.

[0010] To prevent soil from clogging the irrigation pipes, the ends of the multiple irrigation pipes furthest from the water distribution channel are designed as closed hemispherical structures.

[0011] Preferably, the irrigation pipe has multiple water outlet holes at its hemispherical closed end, which are evenly distributed on the outer side of the hemisphere.

[0012] To improve the adaptability of irrigation pipes to root systems at different depths, multiple irrigation pipes are evenly arranged along the circumference of the water distribution channel, and the lengths of the different irrigation pipes are all different.

[0013] Preferably, the irrigation pipe is made of a flexible rigid plastic, and the bending angle is adapted to different root lengths.

[0014] The beneficial effects of this utility model are as follows: This invention forms an irrigation system that integrates rainwater collection, storage, and root irrigation by setting up a ring-shaped water storage tank around the fruit tree and multiple irrigation pipes connected to the water distribution trough. The device can effectively collect and store rainwater in the water storage tank, solving the problem of difficult irrigation of fruit trees in water-scarce mountainous areas from the source, greatly saving water resources and irrigation costs. In addition, there are also storage bags inside the water distribution trough that can store nutrients, which can also be transported to the roots of the fruit tree during irrigation.

[0015] Furthermore, by extending multiple irrigation pipes of varying lengths into the root zone of the fruit trees, precise and uniform irrigation is achieved for roots at different depths and locations. The ends of the irrigation pipes feature a hemispherical closed structure with multiple outlet holes, effectively preventing soil blockage and ensuring that water seeps evenly into the soil around the roots. This design guarantees that water directly reaches the core water-absorbing areas such as the taproot and lateral roots, improving water use efficiency and irrigation effectiveness.

[0019] Example like Figure 1-4 The purpose of this water-saving fruit tree root irrigation device is to solve the problems of water shortage, irrigation difficulties, low water resource utilization, and difficulty in ensuring that water reaches the deep roots of fruit trees evenly in mountainous areas. This embodiment provides a water-saving fruit tree root irrigation device, including a ring support 1 that is arranged around the outside of the fruit tree trunk. The ring support 1 is fixed to the ground by a plurality of support devices 7 that are arranged around its circumference and evenly distributed, and the end away from the ring support 1 is buried in the soil to ensure the stability of the irrigation device in the uneven terrain of mountainous areas.

[0020] A water storage tank 2 is installed above the ring-shaped support 1. The water storage tank 2 is composed of multiple water storage units spliced ​​together. In this embodiment, the water storage tank 2 is composed of two water storage units spliced ​​together, and each water storage unit is a single arc-shaped closed individual. The spliced ​​water storage tank 2 tightly surrounds the outside of the vertical projection of the fruit tree trunk, and the structure of the water storage tank 2 is flared from the bottom to the opening direction. In order to prevent fallen leaves, dead branches and other debris from clogging the water storage tank 2, a filter screen 6 is also installed on the top of the water storage tank 2.

[0021] At the bottom of the water storage tank 2, a water distribution trough 3 is connected via a water supply pipe 4. Each water storage unit has a water distribution trough 3 below it. Multiple irrigation pipes 5 are installed at the end of the water distribution trough 3 away from the water supply pipe 4. The irrigation pipes 5 are evenly arranged around the circumference of the water distribution trough 3. The other end of the irrigation pipe 5 of the water supply pipe 4 extends towards the root system of the fruit tree. The irrigation pipe 5 located inside the water distribution trough 3 extends to the top of the water distribution trough 3. The axis of the irrigation pipe 5 is not aligned with the axis of the water supply pipe 4. Multiple water inlet holes are opened on the pipe wall of the irrigation pipe 5 located inside the water distribution trough 3. The holes are evenly distributed on the pipe wall of the irrigation pipe 5.

[0022] To facilitate water volume control, a float 8 is installed inside the water distribution trough 3. The float 8 is made of lightweight foam material and is fitted onto the outside of the irrigation pipe 5 located inside the water distribution trough 3. The float 8 is a one-piece structure and can move freely up and down along the irrigation pipe 5. The side of the float 8 near the top of the water distribution trough 3 has an arc-shaped structure, and a protrusion that can block the water supply pipe 4 is provided at the position of the float 8 directly below the water supply pipe 4.

[0023] To accommodate root systems of varying lengths, the irrigation pipe 5 comprises multiple pipes of different lengths. To prevent soil blockage of the pipes buried in the soil, the end extending to the root system is a closed hemispherical structure with multiple water outlets evenly distributed on the outer surface of the hemisphere. For better adjustment of the irrigation pipes 5 at different locations, the outer diameters of the different pipes 5 are identical, while their inner diameters differ. Furthermore, the irrigation tank is made of flexible, rigid plastic, and its bending angle is adjusted according to the different lengths from the water distribution channel 3 to the root system.

[0024] Please refer to the appendix. Figure 1-4 In this embodiment, the placement of the ring-shaped support 1 is first determined with the tree trunk as the center, ensuring it is located near the outer edge of the tree's vertical projection to maximize rainwater collection. The lower ends of multiple support devices 7 are firmly inserted into the soil, forming a ring of support points around the tree. The ring-shaped support 1 is then fixed using the support devices 7. A water storage tank 2, composed of arc-shaped individual water storage units, is laid on the ring-shaped support 1, fully extended and surrounding the tree trunk. A filter screen 6 is fixedly installed at the bottom of the water storage tank, and a fixing ring 9 is wrapped around the outside of the water storage tank 2 to secure it. Then, one end of the water pipe 4 is connected to the outlet at the bottom of the water storage tank 2, and the other end is fixedly connected to the water distribution trough 3. Finally, based on the main distribution direction of the tree's roots, the laying paths of multiple irrigation pipes 5 are planned, and irrigation pipes 5 with different inner diameters are installed according to the distance from the water distribution trough 3 to the roots, ensuring that the irrigation pipes 5 extending to the roots are buried close to the roots.

[0025] When the water tank 2 is empty or the water level is very low, the water supply pipe 4 cannot supply water to the water distribution trough 3, and the water distribution trough 3 is dry. The float 8 remains stationary at the bottom of the water distribution trough 3 under the influence of gravity. When rainfall occurs or a water source is injected, the water tank 2 collects enough water, and the water flows into the water distribution trough 3 under the influence of gravity through the water supply pipe 4. The water level in the water distribution trough 3 gradually rises, causing the float 8 to float upwards. When the water level overflows the inlet hole at the lowest position of the irrigation pipe 5, the water begins to flow into the irrigation pipe 5 through the hole and eventually seeps out from the outlet hole at the end of the irrigation pipe 5, thus irrigating the root system.

[0026] As irrigation progresses, if the water level in storage tank 2 drops, causing the water supply rate from water pipe 4 to be less than the outflow rate from irrigation pipe 5, the water level in distribution trough 3 will also drop. The float 8 will then descend accordingly. When the water level falls below all through-holes, the lower surface of the float 8 will block the lower inlet through-hole. Simultaneously, due to the presence of the float 8, the water below it will be quickly evacuated, and air will enter irrigation pipe 5 through the upper through-hole, creating a siphon effect and rapidly stopping irrigation. This mechanism effectively prevents ineffective evaporation and over-irrigation, improving the water-saving efficiency of the device.
