Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation equipment, in particular to a planting watering drip irrigation equipment. Background Art

[0002] Drip irrigation uses pipes to deliver water to the roots of crops through nozzles or drippers with smaller diameters for local irrigation. It is the most effective way of water-saving irrigation in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas.

[0003] However, its disadvantages are also very obvious. The water flow rate in the drip irrigation pipe is slow, and the irrigation water is mostly taken from nature, which contains a lot of impurities and scale. After long-term use, the drip irrigation nozzle is easy to scale and clog, resulting in a decrease in drip irrigation efficiency. If it is completely clogged, it will not have any irrigation effect, which is extremely unfavorable for agricultural planting irrigation.

[0004] The traditional way is to remove the clogged drip irrigation nozzle, clean the scale inside, and then reinstall it, which is very time-consuming and inefficient. For this reason, we proposed a planting watering drip irrigation equipment. Utility Model Content
