Description

Technical Field

[0001] This invention relates to the field of garden irrigation technology, and in particular to a deep seepage irrigation device for the root system of large garden trees. Background Technology

[0002] In the maintenance of large garden trees, in order to save water efficiently, reduce resource waste, promote root development, enhance tree resistance, optimize water and fertilizer absorption, and improve growth quality, drip irrigation technology with columnar or rod-shaped drip irrigation devices as the core is often adopted. This technology involves vertically inserting columnar or rod-shaped drip irrigation devices into the deep soil layer, using a single-point or multi-point layout, and connecting the top to a delivery pipe, so that water slowly seeps out from the drip irrigation holes on the side wall of the drip irrigation device and directly reaches the dense root area, completing the precise irrigation of the root system of large garden trees.

[0003] For example, existing application number CN202210950515.2 discloses a vertical drip irrigation device for fruit trees and its usage method, belonging to the field of fruit tree irrigation technology. It includes a spindle-shaped drip irrigation pipe; the upper part of the pipe has an outward-facing flange forming an inlet; the pipe wall has several outlets; a substrate layer is provided on the outer side of the pipe; the substrate layer is filled with several perforated jujube pits. Based on the density and location of the fruit tree root system, the drip irrigation pipe has a spindle-shaped tubular structure, with a thicker pipe in densely rooted areas and a thinner pipe in sparsely rooted areas, effectively improving water utilization efficiency. Rainwater can be collected through the inlet, and artificial watering is also possible. The perforated jujube pits forming the substrate layer attract new roots through the small holes into the pits. Because the small holes restrict root thickness, they create adverse stimuli, which is beneficial for improving the reproductive growth capacity and fruit quality of the fruit trees. The overall structure is simple, easy to implement, and highly practical.

[0004] However, the irrigation holes of existing columnar irrigation devices are in a state of long-term openness. Therefore, silt, soil particles and tree roots can easily enter the irrigation device through the irrigation holes. This not only easily causes the irrigation holes to become blocked, making it difficult for water and nutrients to penetrate normally and affecting tree growth, but also can cause the pipe to break when the blockage is severe. At the same time, the roots that have entered the irrigation device are easily broken by the water flow or damaged by long-term compression, eventually leading to root rot and increasing the risk of trees being infected by diseases and pests. Summary of the Invention

[0005] In view of this, the present invention provides a deep seepage irrigation device for the root system of large garden trees. During use, the device utilizes an opening and closing control mechanism composed of an opening and closing control pipe, an elastic reset component, and a drive auxiliary blade to automatically control the opening of the irrigation holes during irrigation and their closure when irrigation stops. During irrigation, the water flow drives the drive auxiliary blade, rotating the opening and closing control pipe to precisely align the water passage hole with the irrigation hole, ensuring smooth water and fertilizer seepage. After irrigation stops, the elastic reset component drives the opening and closing control pipe to reset, completely covering the irrigation hole and preventing blockage caused by silt and soil particles. This also prevents the pipe from rupturing due to excessive pressure from blockage, extending the device's service life. The automatic control of the irrigation holes during irrigation and closure when irrigation stops protects the tree root system and reduces the risk of pests and diseases. In the closed state, the irrigation holes prevent tree roots from growing into the irrigation pipe, avoiding root damage from water flow or long-term compression, reducing the risk of root rot, and thus lowering the probability of pest and disease infection caused by root damage, ensuring the health of the trees. The device features a multi-stage filtration and anti-clogging structure. The auxiliary filter in the water inlet intercepts large impurities in the water flow, while the pulverizing impeller on the drive shaft crushes undissolved water and fertilizer particles to a suitable size. The rotation and sliding motion of the filter support effectively prevents clogging of the filter media, ensuring smooth water and nutrient delivery and improving irrigation stability. It also enhances water and fertilizer utilization efficiency, enabling precise irrigation with a distributed layout of multiple water delivery pipes and multiple drip irrigation pipes. This adaptable to the distribution range of large tree root systems, allowing water and fertilizer to reach densely rooted areas directly. The pulverizing impeller's fine processing of undissolved water and fertilizer particles promotes nutrient absorption and conversion in trees, reducing water and fertilizer waste and balancing water conservation with efficient maintenance. It also promotes deep root development and enhances tree resilience. Furthermore, the drip irrigation holes employ a conical hole structure with an outer diameter larger than the inner diameter, conforming to the Venturi principle. This accelerates water and fertilizer seepage while reducing the risk of particle retention and clogging. Simultaneously, it prevents high-pressure rupture of pipes due to blockage, extending the overall service life of the device.

[0010] Furthermore, a positioning auxiliary frame is rotatably connected to the bottom end of the transmission shaft; The filtration auxiliary mechanism also includes a positioning support column, which is laterally rotatably connected to the lower end of the inner side of the water intake section.

[0011] Furthermore, the filter auxiliary mechanism also includes: a driving bevel gear and a driven bevel gear, wherein the driving bevel gear is coaxially fixedly connected to the bottom end face of the transmission support shaft; the driven bevel gear is coaxially fixedly connected to the positioning support column, the driving bevel gear and the driven bevel gear mesh with each other, and the number of teeth of the driving bevel gear is greater than the number of teeth of the driven bevel gear; the positioning auxiliary frame covers the outside of the driving bevel gear and the driven bevel gear.

[0016] Beneficial effects

[0017] In use, this invention utilizes an opening and closing control mechanism comprised of an opening and closing control tube, an elastic reset component, and a drive auxiliary blade to automatically control the opening of the irrigation holes during irrigation and their closing when irrigation stops. During irrigation, the water flow drives the drive auxiliary blade to rotate the opening and closing control tube, ensuring precise alignment between the water passage and the irrigation hole, thus guaranteeing smooth water and fertilizer seepage. After irrigation stops, the elastic reset component drives the opening and closing control tube to reset, completely covering the irrigation hole and preventing blockage caused by silt and soil particles from entering. This also prevents the pipe from rupturing due to excessive pressure from blockage, extending the device's service life.

[0018] When in use, this invention protects tree roots and reduces the risk of pests and diseases by automatically controlling the opening of the irrigation holes during irrigation and closing them when irrigation stops. When the irrigation holes are closed, they can prevent tree roots from growing into the irrigation pipe, avoiding root damage from water flow or long-term compression after root invasion, reducing the risk of root rot, and thus reducing the probability of tree infection by pests and diseases caused by root damage, ensuring the healthy growth of trees.

[0019] When in use, the device is equipped with a multi-stage filtration and anti-clogging structure. The auxiliary filter frame in the water receiving section first intercepts large impurities in the water flow. The crushing impeller on the transmission shaft can crush undissolved water and fertilizer particles to a qualified particle size. The rotation and up-and-down sliding motion of the filter support can effectively prevent the filter media from clogging, ensure smooth water flow and nutrient delivery, and improve irrigation stability.

[0020] When in use, this invention improves water and fertilizer utilization efficiency, enabling precise irrigation through a distributed layout of multiple water delivery pipes and multiple seepage irrigation pipes. It can adapt to the distribution range of tree roots, allowing water and fertilizer to reach the dense root area directly. The pulverizing impeller refines undissolved water and fertilizer particles, promoting the absorption and transformation of nutrients by trees, reducing water and fertilizer waste, and taking into account both water conservation and efficient maintenance needs. At the same time, it helps deep root development and enhances the tree's resistance to adverse conditions.

[0021] Furthermore, when in use, the drip irrigation hole adopts a conical hole structure with an outer diameter larger than the inner diameter, which conforms to the Venturi tube principle. This not only accelerates the seepage speed of water and fertilizer but also reduces the risk of particle retention and blockage. At the same time, it avoids high-pressure rupture of the pipeline due to blockage, thus extending the overall service life of the device. Attached Figure Description

The opening and closing control pipe 6 is rotatably disposed at the inner end of the drip irrigation pipe 5.
