Water-saving drip irrigation device for greenhouse seedling culture

Abstract

The invention relates to the technical field of irrigation equipment, and discloses a water-saving drip irrigation device for greenhouse seedling culture, which comprises a water delivery main pipe, the head end of the water delivery main pipe is communicated with an output pipeline of a water delivery pump, and the tail end of the water delivery main pipe is fixedly provided with a stop valve. Through the arrangement of the filter cloth and the swing plate, when water enters the water changing box from the bent pipes, the water is firstly filtered by the filter cloth, impurities in the water are filtered and intercepted, the intercepted impurities can be concentrated to the middle along the inclined surface of the filter cloth due to the fact that the filter cloth is in a funnel shape, and then when the filter cloth in one bent pipe is blocked, the filter cloth in the other bent pipe is blocked. When the filter cloth rotates, the flow rates of water entering the water changing box through the bent pipes on the two sides are different, then the impact degrees on the swing plate are different, the swing plate loses balance and swings, and then in the swing process of the swing plate, the filter cloth is pushed and pulled through the pulling spring, so that the filter cloth is stirred, and impurities are shaken off from the filter cloth.

Description

technical field [0001] The invention relates to the technical field of irrigation equipment, in particular to a water-saving drip irrigation device used for raising seedlings in greenhouses. Background technique [0002] Compared with sprinkler irrigation, drip irrigation has higher water-saving and yield-increasing effects. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It can be applied to irrigation of fruit trees, vegetables, commercial crops and greenhouses. It can also be used for field crop irrigation in dry and water-deficient places. At present, drip irrigation technology has gradually been widely used in the cultivation of greenhouses. Through drip irrigation technology, the water consumption of crops in agricultural production can be precisely controlled, which is not only conducive to the growth of crops, but also avoids excessive irrigation or excessive irrigation. The stunted growth and even death caused b...

Problems solved by technology

[0003] Most of the currently used drip irrigation devices use pipes to be laid in the greenhouse, then drill holes in the pipes at the required positions, and then supply water to meet the needs of water supply, but in this process, the requirements for water quality are high. There should be no impurities in the water. If there are too many impurities in the water, it will easily cause the dripper to scale, cause blockage, cause no water to flow out of the water outlet, affect the water demand of the crops, and cause the crops to dry up. Control the size of the water outlet, and then effectively control the water output, resulting in different water output everywhere, resulting in differences in crop growth, and directly puncture the water pipe, and after the water pipe is pressurized, it is easy to make the water pipe Cracks, reducing the service life of water pipes
