Abstract
Description
Technical Field
[0001] This application relates to a drip irrigation device for nutrient solution in garden seedlings. Background Technology
[0002] Nutrient solution drip irrigation refers to the localized irrigation of nutrient-rich water to the roots of garden seedlings through water pipes. This not only saves water but also provides fertilizer, promoting better root development and offering more effective and direct treatment for pests and diseases. However, nutrient solution drip irrigation also has some drawbacks, particularly its current structural design, which is prone to clogging. Therefore, structural improvements are needed to mitigate or eliminate these problems as much as possible. Utility Model Content
[0003] To address the aforementioned problems, this application proposes a drip irrigation device for nutrient solution in garden seedlings. The device includes an outer guide pipe, within which several drip irrigation structures are arranged, and several drip irrigation ports are positioned at the locations corresponding to the outer guide pipe. Each drip irrigation structure includes a central pipe located in the middle, outer edge support rings on both sides of the central pipe, several through-holes in the middle of the central pipe, a central receiving space outside the through-holes, anti-backflow structures on both sides of the central receiving space, and a drip irrigation space between the anti-backflow structures and the outer edge support rings. The drip irrigation ports are configured in conjunction with the drip irrigation space. This application utilizes a drip irrigation structure within an outer guide pipe. The drip irrigation structure allows for the extraction of internal water through the drip irrigation space, and the internal anti-backflow structures prevent external soil or other contaminants from entering, ensuring smooth nutrient solution flow and preventing blockage at the drip irrigation ports.
[0004] Preferably, the outer edge support ring includes an inner ring and an outer ring disposed on the inner and outer sides, an inner groove is disposed between the inner ring and the outer ring, and a plurality of transverse spacers are disposed between the inner ring and the outer ring.
[0005] Preferably, the anti-backflow structure includes a transverse connecting groove that communicates with the drip irrigation space. The side of the transverse connecting groove away from the drip irrigation space is connected to a ring-shaped groove surrounding the central pipe, and the other end of the ring-shaped groove is connected to the central receiving space.
[0006] Preferably, the transverse connecting groove is arranged along the axial direction of the central pipe, and several spaced-apart flow channel baffles are provided on the side wall of the transverse connecting groove. This application uses the combined effect of the transverse connecting groove and the annular side groove. The transverse connecting groove can basically prevent soil from seeping into the interior, ensuring the reliability and stability of the structure and avoiding blockage.
[0007] Preferably, the annular side channel includes a middle partition plate disposed on the other side relative to the transverse connecting channel. A first lateral flow channel is disposed on one side of the middle partition plate, and the first lateral flow channel is composed of a plurality of first annular plates fixedly connected to the side wall of the central pipe at intervals. A second lateral flow channel is disposed on the other side of the middle partition plate, and the second lateral flow channel is composed of a plurality of second annular plates fixedly connected to the side wall of the central pipe at intervals. One side of the first lateral flow channel is connected to the central receiving space, and the other side is connected to the second lateral flow channel. The other side of the second lateral flow channel relative to the first lateral flow channel is connected to the transverse connecting channel. This application uses a combination of a first lateral flow channel and a second lateral flow channel arranged in a zigzag manner, which, while ensuring flow stability, can also achieve a labyrinth seal effect, ensuring the continuity of nutrient solution drip irrigation and minimizing or delaying the occurrence of blockage.
[0008] Preferably, the through-hole is a plurality of square holes spaced apart.
[0009] Preferably, the number of drip inlets is not less than three and they are evenly distributed relative to the outer surface of the external guide tube.
[0010] This application can bring the following beneficial effects:
[0011] 1. This application adopts a drip irrigation structure installed inside an external guide pipe. The drip irrigation structure can use the drip irrigation space to export internal water, and then use the internal anti-backflow structure to prevent external soil and other substances from entering the interior, ensuring the smooth flow of nutrient solution and avoiding blockage at the drip irrigation inlet.
[0012] 2. This application uses a combination of transverse connecting grooves and ring side grooves. The transverse connecting grooves can basically prevent soil from seeping into the interior, ensuring the reliability and stability of the structure and avoiding blockage.
[0013] 3. This application adopts a combination of a first lateral flow channel and a second lateral flow channel with a folded configuration. While ensuring the stability of the flow, it can also achieve a labyrinth-like sealing effect, ensuring the continuity of nutrient solution drip irrigation and avoiding or delaying the occurrence of blockage as much as possible.
