Therefore, generally, the drip heads are set to be small and numerous, and the spraying holes are also dense. So when the solubility of the selected fertilizer is not good, insoluble or slightly soluble substances are generated during the stirring and dissolving reaction, substances that are not completely filtered successfully after the fertilizer passes through the water source filter and the automatic backwashing filter, and sediment and other particulate matters in the water are used to spray and fertilize the vegetable field through the drip irrigation pipe and drip heads, it will cause the blockage of the drip heads. Seriously, it may affect the normal operation of the entire system. When the drip heads are blocked, the water output will be uneven, the spraying area will be affected differently, resulting in inconsistent growth of the plants, affecting the yield and quality, and also reducing the service life of the product.

The filtering assembly is communicated with the plurality of delivery pipelines 2 and is used for filtering the fertilizer medium discharged from the delivery pipeline 2 after the fertilizer mixing barrel 1 is not fully stirred. The circulating delivery assembly is communicated with the filtering assembly and is used for re-delivering the fertilizer medium filtered by the filtering assembly to the fertilizer mixing barrel 1 for circulating stirring.

[0042] In this embodiment, the filtering component includes a filtering box 101, a filtering plate 102, a Y-type pipeline filter 103, a medium discharge port 104, a fertilizer discharge port 105, a fertilizer delivery pipe 106, and a second valve 107. The interior of the filtering box 101 is divided into a filtering chamber and a delivery chamber. It should be noted that a plurality of partition plates 6 are provided inside both the filtering chamber and the delivery chamber to separate each medium discharge port 104 and each fertilizer discharge port 105, so as to separate the fertilizers and prevent the fertilizers from mixing together, which may affect the effect after spraying and irrigating the vegetable field 3. The filtering plate 102 is arranged inside the filtering box 101. Each delivery pipeline 2 extends into the filtering chamber and is connected to the Y-type pipeline filter 103. And a filter screen 9 is provided inside the Y-type pipeline filter 103. A plurality of medium discharge ports 104 are all arranged at the bottom of the filtering chamber, and a plurality of fertilizer discharge ports 105 are all arranged at the bottom of the delivery chamber. The fertilizer delivery pipe 106 is connected to the fertilizer discharge port 105, and the second valve 107 is installed on the fertilizer delivery pipe 106.

[0043] In this embodiment, the circulating delivery component includes a circulating pipe 201 and a solid-liquid-gas delivery pump 202. One end of each circulating pipe 201 is respectively connected to each medium discharge port 104, and the other end of each circulating pipe 201 is respectively connected to each fertilizer stirring barrel 1. The solid-liquid-gas delivery pump 202 is installed on each circulating pipe 201.

[0044] In this embodiment, the irrigation component includes a main pipeline 301, a ground-inserted micro-spray pipeline 302, a hanging sprinkler pipeline 303, and a Y-type filtering sprinkler head 304. The main pipeline 301 is connected to the automatic backwashing filter 8. The ground-inserted micro-spray pipeline 302 extends into the vegetable field 3, and the ground-inserted micro-spray pipeline 302 is connected to the main pipeline 301.

[0045] In summary, the working principle of the integrated drip irrigation device for vegetable seedling cultivation with water and fertilizer is as follows: When spraying and irrigating the vegetable field 3, first, the fertilizer and water in the fertilizer mixing tank 1 are stirred. Valve 1 4 is opened, and the mixture is transported through the bottom conveying pipe 2 to the Y-type pipe filter 103 in the filter tank 101 connected thereto. The undissolved fertilizer is filtered into the filter chamber through the filter screen 9 inside the Y-type pipe filter 103. Through the circulation pipe 201 and the solid-liquid-gas transfer pump 202 connected to the medium discharge port 104 at the bottom of the filter chamber, it is transported back to the fertilizer mixing tank 1 for cyclic stirring. The stirred fertilizer is filtered by the Y-type pipe filter 103. Valve 2 107 installed on the fertilizer conveying pipe 106 is opened, and the fertilizer is transported through the fertilizer conveying pipe 106 connected to the conveying chamber to the water source filter 7 for the first filtration and mixing. Then, it passes through the automatic backwash filter 8 connected to the water source filter 7 for the second filtration and mixing. After the filtration is completed, the fertilizer flows through the main pipe 301 connected to the automatic backwash filter 8 to the ground-insert micro-spray pipe 302 and the hanging sprinkler pipe 303 respectively. The Y-type filter nozzle 304 on the hanging sprinkler pipe 303 performs the final filtration, leaving the medium or sediment that cannot be sprayed in the closed end of the Y-type filter nozzle 304. After the spraying and irrigation are completed, the Y-type filter nozzle 304 is taken out, processed, and reinstalled, reducing the possibility of nozzle clogging.
