With the acceleration of urbanization, the city is expanding, and the narrow space in the city, such as the road dividing green belt and the planting area between dense buildings, is increasing. The irrigation demand for these narrow spaces is increasingly prominent. An efficient irrigation system not only can improve the utilization rate of water resources and fertilizers, reduce costs, but also can improve the irrigation effect and promote plant growth, which is of great significance to the improvement and sustainable development of urban ecological environment.

Irrigation water and fertilizers inevitably contain silt, scale or incompletely dissolved particles. These impurities are easy to block the precision irrigation sprinklers or drip irrigation pipes, causing the irrigation system to malfunction. Therefore, the filter is an essential but easily malfunctioning component in the pump station. The existing filtering scheme has the following defects: a simple mesh filter needs to be frequently disassembled and manually cleaned, which will bring a huge maintenance workload in multiple dispersed urban projects.

[0051] Embodiment two, referring to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 , the difference between the embodiment and the embodiment one is that the stripping assembly 6 is further included, which is used to avoid that the water fertilizer delivered into the filter bin 41 blocks the inlet end of the filter bin 41, the stripping assembly 6 includes the processing pipe 61 arranged at the connection position of the delivery pipeline 11 and the filter bin 41, the stripping ring 62 rotatably arranged on the inner wall of the processing pipe 61, and the limiting ring 63 used to limit the stripping ring 62, the two ends of the processing pipe 61 are combinedly connected with the delivery pipeline 11 and the filter bin 41 respectively, the adjusting opening 64 is arranged through the outer part of the processing pipe 61, the limiting ring 63 is rotatably arranged on the outer part of the processing pipe 61, the inner side of the limiting ring 63 is provided with the combination block 65, the combination block 65 passes through the adjusting opening 64 and is connected with the outer part of the stripping ring 62, when the water fertilizer in the delivery pipeline 11 is delivered to the filter bin 41, the inlet end of the filter bin 41 is easily blocked, which affects the normal operation of the irrigation system; the stripping assembly 6 is arranged, the processing pipe 61 is used to connect the delivery pipeline 11 and the filter bin 41, so that the installation space and the working position of the stripping ring 62 are provided; the stripping ring 62 rotatably arranged on the inner wall of the processing pipe 61 can be rotated under the driving of the limiting ring 63, the limiting ring 63 is connected with the stripping ring 62 through the combination block 65 on the inner side of the limiting ring 63 and the adjusting opening 64 on the outer part of the processing pipe 61, so that the linkage of the two is realized; when the limiting ring 63 rotates, the stripping ring 62 will swing in the processing pipe 61, so that the water fertilizer delivered into the filter bin 41 is stirred, the substances that may cause blockage are stripped and dispersed, and the accumulation and blockage of the water fertilizer at the inlet end of the filter bin 41 are effectively avoided.

[0052] Reference Figure 6In the embodiment, more specifically, the two ends of the stripping ring 62 extend into the conveying pipeline 11 and the filter bin 41 respectively, and the inner wall of the stripping ring 62 is provided with a plurality of stripping teeth 621 arranged at equal intervals, which further improves the stripping efficiency of the blockage. The two ends of the stripping ring 62 extend into the conveying pipeline 11 and the filter bin 41 respectively, which can increase the contact range with the water and fertilizer conveyed into the filter bin 41. The plurality of stripping teeth 621 arranged at equal intervals on the inner wall of the stripping ring 62 can more fully and uniformly act on the substances that may cause the blockage of the inlet end of the filter bin 41 when the stripping ring 62 swings. The sharp structure of the stripping teeth 621 can scrape and cut the blockage, thereby further effectively improving the stripping efficiency of the blockage and preventing the water and fertilizer conveyed in the conveying pipeline 11 from blocking the inlet end of the filter bin 41.

When the rotating motor 67 on the outside of the treatment pipe 61 works, the output end drives the driving gear 68 to rotate, and the limiting ring 63 can rotate due to the engagement between the driving gear 68 and the rack 631 on the outer surface of the limiting ring 63. Since the combined block 65 on the inner side of the limiting ring 63 is connected to the outside of the stripping ring 62 through the adjusting opening 64 of the treatment pipe 61, the limiting ring 63 can drive the stripping ring 62 to swing when the limiting ring 63 rotates. This structure design can effectively strip the blockage in the water and fertilizer conveyed into the filter bin 41 from the conveying pipeline 11, thereby preventing the blockage of the inlet end of the filter bin 41.
