Background technique

my country is a country that is extremely short of water resources. The per capita water resources are only 1/4 of the international average level, but the population ranks first in the world. In recent years, my country, especially the main grain-producing areas in the north and the ecologically fragile areas, have been continuously suffering from severe droughts. The frequency and scope of droughts have been expanding, and the duration and losses have also been increasing, endangering my country's food security and ecology. surroundings. Rational use of water resources, especially agricultural water resources, and the promotion of water-saving irrigation technologies have become important strategies related to the national economy and people's livelihood. At present, related surface water-saving irrigation emitters have problems such as clogging in varying degrees, serious surface evaporation loss, underground irrigation clogging and short service life. Underground drip irrigation is a form of underground enclosure irrigation. It is a new type of high-efficiency water-saving irrigation technology developed on the basis of drip irrigation technology. It is an irrigation method in which the mixed solution slowly flows out and infiltrates into the soil in the root zone of the crop, and then diffuses the water to the root layer by capillary action or gravity for the crop to use. Because it can fully meet the water and fertilizer necessary for crops in different stages of the growth process, it can be directly sent to the roots of crops in an accurate and appropriate amount, so as to save water, fertilizer, increase production and reduce pests and diseases. It has become a global research hotspot. question.

Contents of the invention

The utility model overcomes the defects of the prior art, and proposes an irrigation device for underground full-seepage irrigation pipelines. It solves the technical problems of pipe blockage and uneven water output, and realizes the advantages of reducing surface evaporation and long service life.

The technical scheme of the utility model is:

An underground full seepage irrigation pipeline irrigation device, comprising a water supply, a pressure valve connected to the water supply through a main pipeline, a pressure gauge connected to one end of the pressure valve, a bypass valve connected to the other end of the pressure gauge through the main pipeline, The end of the main road is sealed and blocked. The full-seepage irrigation pipeline emitter connected with the bypass valve through a flange has a plurality of micropores on its main body, and the other end of the full-seepage irrigation pipeline emitter main body is sealed.

Further, multiple bypass valves are included.

Further, a plurality of seepage irrigation pipes are included and the number is the same as that of the bypass valve.

Further, the water supply has a pressurizing device.

Further, the full-seepage irrigation pipeline emitter is made of elastic rubber and polyethylene, and these two materials are well-known materials in the prior art.

The water supply device mainly provides water source and pressurizes the water source for the full seepage irrigation pipeline emitter. The full-seepage irrigation pipe emitter is a new type, uniform, anti-clogging water-saving irrigation emitter. The pressure valve is connected to the full-seepage irrigation pipeline emitter. By adjusting the size of the pressure valve, the water output of the full-seepage irrigation pipeline emitter can be controlled, and the water output from each micropore in the full-seepage irrigation pipeline emitter is uniform. The full-seepage irrigation pipeline irrigation device is in When working, firstly adjust the pressure valve to make the inside of the full-seepage irrigation pipeline emitter be in a low-pressure state. In the case of full-seepage irrigation pipeline emitters, the pressure at the tail increases first, and the pressure is gradually sent to the front section. When the pressure of the entire pipeline of the full-seepage irrigation pipeline emitter is the same, the water output can be consistent. The distance between the two drip outlets of the full-seepage irrigation pipe emitter can be adjusted according to the pressure, which can ensure water saving, and perform precise irrigation according to the shrinkage capacity of the elastic rubber and the degree of soil moisture. The water in the water supply is delivered to the roots of the crops. The utility model utilizes a full-seepage irrigation pipeline sprinkler and a pressure valve to perform precise and uniform field irrigation. The full-seepage irrigation pipeline sprinkler is made of elastic rubber and polyethylene, and can replenish water to different crops through the pressure during irrigation. Full-seepage irrigation The water outlet size of the crack opening on the pipeline sprinkler can be adjusted according to the crops, and the length of the crack opening can be adjusted by a pressure valve. After long-term use of full-seepage irrigation pipes, like other pipes, problems such as blockage will occur. Full-seepage irrigation pipe emitters are buried in the ground according to the distribution of crop roots. Replacement is time-consuming and labor-intensive, and damages the roots. When the water volume is small, adjust the pressure valve to make the pressure reach the critical value of pipe burst (test during pipeline production). In that way, all the tiny impurities and accumulated microorganisms on the inner wall of the pipeline are discharged (large particles of impurities have little effect on pipeline blockage), so the device can solve problems such as pipeline blockage and uneven water output.

The technical effect of the technical solution of the utility model is to provide a full-seepage irrigation pipeline irrigation device, which solves the technical problems of pipeline blockage and uneven water output. It realizes the advantages of reducing surface evaporation and long service life, so as to achieve the effect of water saving and income increase for crops and fruit trees, increase farmers' production and income, and landscape greening, etc., while saving surface and underground water.
