Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to a drip irrigation device for forestry planting. Background Technology

[0002] Currently, drip irrigation technology is widely used in forestry planting in arid or water-scarce areas to improve water resource utilization efficiency and promote plant growth. However, in practical applications, the layout of drip irrigation systems often faces significant challenges due to complex terrain and uneven vegetation distribution. Typically, drip irrigation pipes need to be adjusted according to the terrain elevation to ensure even water distribution to the roots of each plant. To achieve this, construction workers must frequently adjust the pipe height and dripper position, especially in areas with large tree spacing, where this adjustment workload increases significantly. Furthermore, existing drip irrigation systems are prone to dripper blockage or uneven water flow due to sediment deposition or water pressure fluctuations during long-term use, thus affecting irrigation efficiency. Maintenance and cleaning are not only time-consuming and labor-intensive but may also interfere with normal planting operations, and overall efficiency needs further improvement. Utility Model Content

[0003] The purpose of this utility model is to provide a drip irrigation device for forestry planting, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a drip irrigation device for forestry planting. The device mainly consists of a main water supply pipe, an adjusting branch pipe installed on the main water supply pipe, a drip irrigation component installed at the end of the adjusting branch pipe, and a support mechanism for fixing the adjusting branch pipe. The main water supply pipe serves as the main structure, and the adjusting branch pipe and the support mechanism are both connected to the main water supply pipe.

[0005] The regulating branch pipe is movably connected to the main water supply pipe via a sliding sleeve. The sliding sleeve has a threaded groove inside, and a knob on the outside that mates with the threaded groove. Rotating the knob moves the sliding sleeve up and down along the main water supply pipe, thus adjusting the height of the regulating branch pipe. The surface of the main water supply pipe has helical protrusions that match the threaded grooves. These helical protrusions, in conjunction with the threaded grooves, allow the sliding sleeve to move and be positioned precisely on the main water supply pipe. The end of the regulating branch pipe has a ball joint, which connects to the drip irrigation assembly via a snap-fit ​​connection. The ball joint allows the drip irrigation assembly to rotate freely within a multi-angle range to accommodate irrigation needs in different directions.

[0006] The support mechanism includes a base, a telescopic rod mounted on the base, and a clamping component installed at the top of the telescopic rod. The clamping component is arc-shaped with an anti-slip pad on its inner side and is fixed to the top of the telescopic rod with bolts. The telescopic rod consists of an inner rod and an outer rod. The inner rod is inserted into the outer rod and fixed with a locking screw. The locking screw passes through the outer rod and abuts against the inner rod, thereby adjusting the length of the telescopic rod. The bottom of the base has tapered feet with the tips pointing downwards, facilitating the stable insertion of the support mechanism into the soil. The arc-shaped opening of the clamping component matches the outer diameter of the adjusting branch pipe, and the clamping component fits tightly against the adjusting branch pipe through the anti-slip pad, preventing the adjusting branch pipe from loosening or shifting during use.

[0007] The drip irrigation assembly includes a drip head, a filter screen inside the drip head, and a flow control valve installed at the drip head outlet. The drip head connects to a ball joint via a snap-fit ​​connection. The filter screen, located at the drip head inlet, is made of multi-layered stainless steel and effectively intercepts impurities such as sediment, reducing the risk of clogging. The flow control valve consists of a valve body and an adjustment knob. The valve body contains a conical valve core, and the adjustment knob is threaded to the valve body. Rotating the knob changes the position of the conical valve core, thus controlling the water flow rate. The drip head outlet has a nozzle with spiral guide grooves on its inner wall. Water flows through these grooves, creating a rotating jet that increases water coverage and improves irrigation uniformity.

[0008] This utility model discloses a drip irrigation device for forestry planting. Through the cooperation of a sliding sleeve and a spiral protrusion on the main water supply pipe, it achieves precise adjustment of the branch pipe height, meeting irrigation needs under complex terrain conditions. The telescopic rod and clamping design of the support mechanism ensures the stability and flexibility of the adjustable branch pipe, avoiding loosening of the device due to terrain changes. The multi-layer filter screen in the drip irrigation assembly significantly reduces the risk of sediment deposition, while the flow regulating valve can flexibly control the water flow according to actual needs, improving water resource utilization efficiency. Furthermore, the spiral guide groove design at the drip head outlet optimizes water flow distribution, ensuring uniform irrigation to the roots of each plant. The overall structure is simple, easy to operate, and suitable for large-scale forestry planting scenarios, significantly improving the efficiency and stability of drip irrigation operations.

[0013] The specific implementation method of this utility model's forestry planting drip irrigation device is described in detail with reference to the accompanying drawings. For example... Figure 1 As shown, the device consists of a main water supply pipe 1, an adjusting branch pipe 2, a support mechanism 11, and a drip irrigation assembly. The main water supply pipe 1 is the core structural component, with the adjusting branch pipe 2 connected to it via a sliding sleeve 3. The support mechanism 11 is used to fix and support the adjusting branch pipe 2 to ensure the stability of the entire device. The drip irrigation assembly is installed at the end of the adjusting branch pipe 2 and is responsible for accurately delivering water to the plant root zone. The following description, in conjunction with the accompanying drawings and specific component labels, details the connection relationships, positional relationships, and mutual cooperation of each part.

[0014] The main water supply pipe 1 is a horizontally arranged pipe with spiral protrusions 5 on its surface. These protrusions 5 are evenly distributed along the axial direction of the main water supply pipe 1 and have a trapezoidal cross-section to facilitate a tight fit with the threaded grooves inside the sliding sleeve 3. The sliding sleeve 3 is fitted onto the outside of the main water supply pipe 1 and is moved and positioned via a knob 4. The inner wall of the sliding sleeve 3 has threaded grooves that match the spiral protrusions 5. When the knob 4 is rotated, the sliding sleeve 3 moves up and down along the spiral protrusions 5, thereby adjusting the height of the regulating branch pipe 2. One end of the regulating branch pipe 2 is fixed to the outside of the sliding sleeve 3 by welding or threaded connection, while the other end is fitted with a ball joint 6. The ball portion of the ball joint 6 is embedded into the end of the regulating branch pipe 2 and connected via a snap-fit ​​structure, allowing the ball joint 6 to rotate freely within a certain angle range to adapt to irrigation needs in different directions.

[0015] The support mechanism 11 includes a base, a telescopic rod 12, and a clamping member 13. The base has tapered feet 14 at its bottom, with the tips pointing downwards for easy insertion into the soil to enhance the stability of the device. The telescopic rod 12 consists of an inner rod and an outer rod. The inner rod is inserted into the outer rod and secured with a locking screw, which passes through the outer rod and abuts against the inner rod, thus allowing for adjustment of the telescopic rod length. The clamping member 13 is installed at the top of the telescopic rod 12 and has an arc-shaped design with an anti-slip pad on its inner side. The clamping member 13 is fixed to the top of the telescopic rod 12 with bolts. The arc-shaped opening size of the clamping member 13 matches the outer diameter of the adjusting branch pipe 2. The clamping member 13 fits tightly against the adjusting branch pipe 2 through the anti-slip pad, preventing the adjusting branch pipe 2 from loosening or shifting during use.

[0016] The drip irrigation assembly includes a drip head 7, a filter screen 8, a flow regulating valve 9, and a nozzle 10. The drip head 7 is connected to a ball joint 6 via a snap-fit. A filter screen 8, made of multi-layered stainless steel, is located near the inlet. The filter screen 8 has three layers, with the pore size gradually decreasing from the inlet to the outlet: 0.5mm for the first layer, 0.3mm for the second, and 0.1mm for the third. This effectively intercepts impurities such as sediment, reducing the risk of clogging. A flow regulating valve 9 is installed at the outlet of the drip head 7. The flow regulating valve 9 consists of a valve body and an adjustment knob. A conical valve core is located within the valve body, and the adjustment knob is threaded to the valve body. Rotating the adjustment knob changes the position of the conical valve core, thereby controlling the water flow rate. The nozzle 10 is located at the very end of the drip head 7. Its inner wall is provided with a spiral guide groove with a spiral angle of 30°. After the water flows through the spiral guide groove, it forms a rotating jet, which increases the water flow coverage and improves irrigation uniformity.

[0017] In practical use, the main water supply pipe 1 is connected to the water source via a pipeline. Water from the source enters the main water supply pipe 1 and flows into the drip irrigation assembly through the regulating branch pipe 2. Users can adjust the height of the regulating branch pipe 2 by rotating the knob 4 to move the sliding sleeve 3 up and down along the spiral protrusion 5 on the main water supply pipe 1, adapting it to the needs of complex terrain, based on the terrain conditions and vegetation distribution. Simultaneously, the ball joint 6 design allows the drip irrigation assembly to rotate freely within a certain angle range to meet irrigation needs in different directions. The tapered insert 14 of the support mechanism 11 is inserted into the soil, the telescopic rod 12 adjusts its length to adapt to differences in terrain height, and the clamping member 13 tightly fits the regulating branch pipe 2 with an anti-slip pad layer, ensuring that the regulating branch pipe 2 does not loosen or shift during use.

[0018] After the water enters the drip irrigation head 7, it first passes through multiple layers of filtration by the filter screen 8 to remove impurities such as mud and sand. Then it enters the flow regulating valve 9. Users can change the position of the conical valve core by rotating the adjustment knob of the flow regulating valve 9, thereby flexibly controlling the water flow according to actual needs. Finally, the water flows through the spiral guide groove of the nozzle 10 to form a rotating jet, optimizing the water flow distribution and ensuring that the roots of each plant receive uniform irrigation.

[0019] In the above embodiments, the connection relationships, positional relationships and mutual cooperation relationships between the main water supply pipe 1, the regulating branch pipe 2, the support mechanism 11 and the various components of the drip irrigation assembly are described in detail. The structural design and assembly method of all components can be realized by existing technical means, and can meet the irrigation needs under complex terrain and uneven vegetation distribution conditions. At the same time, it significantly reduces the risk of drip head clogging and improves water resource utilization efficiency and irrigation uniformity.

[0020] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0021] When actually setting up a drip irrigation system, the main water supply pipe 1 needs to be laid horizontally in a suitable location in the woodland and connected to the water source via a pipe. The surface of the main water supply pipe 1 has spiral protrusions 5, and a sliding sleeve 3 is fitted onto the outside of the main water supply pipe 1, with its inner wall threaded groove tightly engaging with the spiral protrusions 5. Users can rotate the knob 4 to move the sliding sleeve 3 up and down along the main water supply pipe 1, thereby adjusting the height of the regulating branch pipe 2. This design allows the regulating branch pipe 2 to be flexibly positioned according to the terrain elevation, ensuring that the water flow is evenly distributed to the root zone of each plant. For example, in areas with steep slopes, users can raise the regulating branch pipe 2 to compensate for the terrain difference; while in flat areas, the regulating branch pipe 2 can be lowered to reduce the space occupied by the system.

[0022] Subsequently, the support mechanism 11 is installed to fix the position of the adjusting branch pipe 2. The tapered insert 14 at the bottom of the base is inserted into the soil to ensure the stability of the support mechanism 11. The telescopic rod 12 consists of an inner rod and an outer rod, and its length is adjusted by locking screws to adapt to different terrain requirements. A clamp 13 is installed at the top of the telescopic rod 12, its arc-shaped opening size matching the outer diameter of the adjusting branch pipe 2, and it fits tightly against the adjusting branch pipe 2 with an anti-slip pad to prevent loosening or displacement during use. This design not only ensures the stability of the adjusting branch pipe 2 but also allows for flexible adjustment of its direction within a certain range to meet the needs of different vegetation distributions.

[0023] After the main water supply pipe 1 and regulating branch pipe 2 are installed, the drip irrigation assembly is attached to the end of the regulating branch pipe 2. The drip head 7 is connected to the ball joint 6 via a snap-fit ​​connection. The ball joint 6 is designed to allow the drip head 7 to rotate freely within a certain angle range, thus adapting to irrigation needs in different directions. When water enters the drip head 7, it first passes through multiple layers of filtration by the filter screen 8. The filter screen 8 is made of three layers of stainless steel, with the pore size of each layer gradually decreasing from the inlet to the outlet, at 0.5mm, 0.3mm, and 0.1mm respectively. This step-by-step filtration mechanism effectively intercepts impurities such as silt, significantly reducing the risk of clogging of the drip head 7. Subsequently, the water flows into the flow regulating valve 9. The user can precisely control the flow rate by rotating the adjusting knob to change the position of the conical valve core. Finally, the water flows through the spiral guide groove of the nozzle 10 to form a rotating jet with a spiral angle of 30°, which increases the water coverage and improves irrigation uniformity.

[0024] In actual operation, water from the water source flows through the main water supply pipe 1 into the regulating branch pipe 2, and then is precisely delivered to the root zone of the plants via the drip irrigation components. Because the height and direction of the regulating branch pipe 2 can be flexibly adjusted, the device can adapt to complex terrain and unevenly distributed forest environments. For example, in areas with large tree spacing, users can adjust the height of the regulating branch pipe 2 and the direction of the drip irrigation head 7 according to the specific location of each plant to ensure that each plant receives adequate irrigation. Meanwhile, the tapered insert 14 and telescopic rod 12 design of the support mechanism 11 further enhance the adaptability of the device, enabling it to remain stable under different terrain conditions.

[0025] Furthermore, the multi-layer filter 8 and flow regulating valve 9 of the drip irrigation system significantly improve the reliability and ease of operation of the device. The multi-layer filter 8 reduces maintenance and cleaning workload by intercepting impurities such as silt and sand in stages. The flow regulating valve 9 allows users to flexibly adjust the water flow according to actual needs, thereby optimizing water resource utilization efficiency. The spiral guide channel design of the nozzle 10 further improves irrigation uniformity, ensuring that the water flow can cover the root area of ​​each plant and avoid poor irrigation effect caused by uneven water distribution.

[0026] In summary, this utility model's forestry drip irrigation device achieves precise adjustment of the height of the branch pipe 2 through the cooperation of the sliding sleeve 3 with the spiral protrusion 5 of the main water supply pipe 1; the design of the tapered insert 14 and telescopic rod 12 of the support mechanism 11 enhances the stability and flexibility of the device; and the design of the multi-layer filter screen 8, flow regulating valve 9, and nozzle 10 of the drip irrigation components significantly reduces the risk of drip head clogging and improves irrigation uniformity and water resource utilization efficiency. The above structural design and operating principle can be achieved using existing technologies and can meet the irrigation needs under complex terrain and uneven vegetation distribution conditions, providing an efficient and stable drip irrigation solution for forestry planting.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
