Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically a water and fertilizer drip irrigation pipe. Background Technology

[0002] Drip irrigation, as one of the core technologies of modern agriculture, combines irrigation with fertilization to achieve precise application and efficient utilization of water and fertilizer resources. This technology can significantly improve water and fertilizer utilization rates, achieving the goals of water conservation, fertilizer conservation, increased yield, and improved efficiency. A typical drip irrigation system usually includes a water and fertilizer tank, a pump, a water distribution network (such as main pipes, branch pipes, and capillary pipes), and irrigation emitters (such as drippers or drip irrigation tubing).

[0003] In the prior art, such as the drip irrigation device for industrialized agricultural planting disclosed in patent CN217217434U, basic drip irrigation functions can be achieved by setting up a water and fertilizer tank, a pump, and a drip irrigation network. Such devices typically include filters in the pipeline to prevent impurities from clogging the emitters and ensure stable system operation.

[0004] However, existing drip irrigation systems still have some limitations that urgently need to be addressed. First, the positions of the drip irrigation branches (or drippers) on the drip irrigation pipes are usually fixed and difficult to adjust once installed. In actual agricultural production, the planting spacing of crops may vary due to differences in variety, region, or agronomic requirements. Fixed drip irrigation points cannot adapt to these changes, resulting in inaccurate application of water and fertilizer to the crop root zone, either wasting resources or causing insufficient irrigation, which affects crop growth.

[0005] Therefore, there is an urgent need for a drip irrigation pipe that can achieve precise and flexible adjustment of drip irrigation location. Utility Model Content

[0006] This invention addresses the aforementioned shortcomings of existing technologies by providing a drip irrigation pipe that allows for flexible adjustment of the pipe's angle and extension length based on the actual plant and row spacing of the crops. This ensures that water droplets are precisely applied to the root zone of each crop, significantly improving the accuracy of water and fertilizer application, preventing resource waste, and meeting the needs of differentiated planting. To achieve the above objectives, this utility model provides the following technical solution: A water and fertilizer drip irrigation pipe includes a drip irrigation main pipe, branch pipes are evenly arranged on the side wall of the drip irrigation main pipe, a rotatable filter box is connected to the branch pipe, a filter cylinder is provided inside the filter box, a water outlet pipe is provided on the side wall of the filter box, and an adjustable-length drip tube is inserted into the end of the water outlet pipe.

[0007] Preferably, the upper end of the filter box is provided with a water inlet pipe, the end of the water inlet pipe is provided with an outer retaining ring, a pressure ring is sleeved on the outside of the water inlet pipe, the pressure ring is threadedly connected to the branch pipe, and a first sealing ring is provided between the branch pipe and the pressure ring. Preferably, the filter cartridge is a cylindrical structure with filter holes evenly distributed on the side wall. A bottom cover is connected to the lower end of the filter cartridge, and a support ring for supporting the filter cartridge is connected to the upper end of the bottom cover. The support ring is threaded to the bottom of the filter box. The bottom cover is pressed against the bottom of the filter box. A second sealing ring is provided between the bottom cover and the filter box. The upper end of the filter cartridge rests against the upper inner wall of the filter box, and the lower end of the water inlet pipe is directly opposite the upper end of the filter cartridge.

[0008] Preferably, the inner diameter of the filter cartridge is larger than the inner diameter of the inlet pipe. Preferably, the bottom cover has a handle at its lower end.

[0009] Preferably, the end of the dropper is fitted with a piston that slides against the inner wall of the water outlet pipe, the piston is made of rubber, and the end of the water outlet pipe is provided with an inner retaining ring.

[0010] Preferably, the dropper has a curved flow-blocking channel inside, and the flow-blocking channel is located near the end of the dropper.

[0011] Preferably, the end of the water outlet pipe is provided with a positioning bolt for fixing the drip tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves dual adjustment of the drip irrigation position in both angle and radial direction by connecting a rotatable filter box to a branch pipe of the main drip irrigation pipe and setting an adjustable-length drip tube on the filter box. Users can flexibly adjust the angle and extension length of the drip tube according to the actual plant spacing and row spacing of the crops, so that water droplets can accurately drip onto the root area of ​​each crop, greatly improving the accuracy of water and fertilizer application, avoiding resource waste, and meeting the needs of differentiated planting.

[0013] 2. This utility model features an independent, easily detachable filter cartridge within the filter box. Before the water and fertilizer enter the dripper, they are filtered by the filter cartridge, effectively intercepting particulate impurities that may clog the dripper, thus protecting it and reducing the risk of blockage. Furthermore, the entire filter cartridge can be easily removed by rotating the bottom cover, making cleaning simple and quick, significantly reducing the long-term maintenance costs and workload of the system.

[0014] 3. This invention incorporates a curved flow-blocking channel (such as an S-shaped channel) inside the dripper. This structure effectively increases the flow resistance of the water and fertilizer fluids, causing them to flow out of the dripper at a slower and more stable speed. This method facilitates the full diffusion and infiltration of water into the soil, avoiding uneven irrigation and soil erosion caused by surface runoff, and ensuring the uniformity and efficiency of irrigation.

[0015] 4. This utility model achieves reliable sealing and flexible locking between the filter box and the branch pipe through the threaded connection of the pressure ring and the branch pipe with the first sealing ring; the bottom cover and the filter box are connected by a support ring threadedly and equipped with a second sealing ring, ensuring the stability of the filter cartridge installation and the sealing of the bottom. The drip tube and the water outlet pipe are connected by an elastic piston and an inner retaining ring, which not only ensures the sealing during extension and sliding but also prevents the drip tube from falling off.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, a drip irrigation pipe includes a main drip irrigation pipe 1, with branch pipes 101 evenly arranged on the side wall of the main drip irrigation pipe 1. A rotatable filter box 3 is connected to each branch pipe 101, and a filter cartridge 5 is provided inside the filter box 3. A water outlet pipe 303 is provided on the side wall of the filter box 3, and an adjustable-length drip tube 4 is inserted into the end of the water outlet pipe 303. Water and fertilizer are filtered by the filter cartridge 5 and then flow out through the drip tube 4, preventing blockage of the drip tube 4. The angle of the drip tube 4 can be adjusted by rotating the filter box 3, and the length of the drip tube 4 can be adjusted to precisely control the drip irrigation position, achieving precision irrigation.

[0019] like Figure 2As shown, the upper end of the filter box 3 is provided with a water inlet pipe 301, and the end of the water inlet pipe 301 is provided with an outer retaining ring 305. A pressure ring 2 is fitted on the outside of the water inlet pipe 301. The pressure ring 2 is threadedly connected to the branch pipe 101. A first sealing ring 302 is provided between the branch pipe 101 and the pressure ring 2. The pressure ring 2 can tighten the outer retaining ring 305 and the branch pipe 101, and the first sealing ring 302 can seal the outer retaining ring 305 and the branch pipe 101. Loosening the pressure ring 2 allows the filter box 3 to rotate, thereby adjusting the angle of the drip tube 4. like Figure 3 As shown, the filter cartridge 5 is a cylindrical structure. Filter holes 501 are evenly provided on the side wall of the filter cartridge 5. A bottom cover 504 is connected to the lower end of the filter cartridge 5. A support ring 502 supporting the filter cartridge 5 is connected to the upper end of the bottom cover 504. The support ring 502 is threaded to the bottom of the filter box 3. The bottom cover 504 is pressed against the bottom of the filter box 3. A second sealing ring 503 is provided between the bottom cover 504 and the filter box 3. The upper end of the filter cartridge 5 rests against the upper inner wall of the filter box 3. The lower end of the water inlet pipe 301 is directly opposite the upper end of the filter cartridge 5. The inner diameter of the filter cartridge 5 is larger than the inner diameter of the water inlet pipe 301 to ensure that water and fertilizer enter the filter cartridge 5. After filtration through the filter cartridge 5, the water and fertilizer enter between the filter cartridge 5 and the filter box 3 and then enter the water outlet pipe 303, flowing into the dripper 4.

[0020] The bottom of the bottom cover 504 is provided with a handle 505. The bottom cover 504 and the support ring 502 can be rotated through the handle 505 to pull out the filter cartridge 5 for easy cleaning.

[0021] like Figure 4 As shown, the end of the dropper 4 is fitted with a piston 401 that slides against the inner wall of the water outlet pipe 303. The piston 401 is made of rubber and is elastic. The piston 401 and the water outlet pipe 303 are press-fitted together, and the piston 401 can seal between the dropper 4 and the water outlet pipe 303. The end of the water outlet pipe 303 is provided with an inner retaining ring 304 to prevent the dropper 4 from detaching from the water outlet pipe 303. The end of the water outlet pipe 303 is provided with a positioning bolt 306 to fix the dropper 4.

[0022] The dripper 4 has a curved flow-blocking channel 402 inside, meaning that the inner cavity of the dripper 4 is S-shaped near the opening. This effectively increases the flow resistance of the water and fertilizer fluids, causing them to flow out of the dripper 4 opening at a slower and more stable speed. This method facilitates the full diffusion and infiltration of water in the soil, avoiding uneven irrigation and soil erosion caused by surface runoff, and ensuring the uniformity and efficiency of irrigation.
