Automatic drip irrigation system

Abstract

The invention provides an automatic drip irrigation system. The automatic drip irrigation system comprises a water inlet spiral pipe, a liquid mixing pipe, a drip irrigation pipe, a return spiral pipe, a mother liquor tank and a mechanical proportional valve; one end of the water inlet spiral pipe is a straight pipe and is connected to an external water source or a water pump, and the other end ofthe water inlet spiral pipe is a spiral pipe and is connected to the side face of one end of the liquid mixing pipe; one end of the drip irrigation pipe is connected to the liquid mixing pipe, and the other end thereof is connected to the return spiral pipe; one end of the return spiral pipe is a straight pipe and is connected to the drip irrigation pipe, and the other end thereof is a spiral pipe and is connected to the liquid mixing pipe; the return spiral pipe and the water inlet spiral pipe are respectively connected to two opposite side faces of the liquid mixing pipe; nutrient solutionmother liquor is added through the mother liquor tank and the mechanical proportional valve to realize simultaneous irrigation and fertilization; and circulating water prolongs the time of forming algae in the pipeline, and at the same time, the flushing of the circulating water is utilized to reduce the clogging speed of a dropper hole. The drip irrigation system provided by the invention has theadvantages of realizing irrigation and fertilization and avoiding clogging.

Description

technical field [0001] The invention belongs to the field of plant planting equipment, in particular to an automatic drip irrigation system. Background technique [0002] Drip irrigation is the use of plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 10mm for local irrigation. [0003] It is currently the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. Its disadvantage is that the dripper is easy to scale and block, so the wate...
