Drip irrigation device for planting plants in water-deficient area

The invention discloses a drip irrigation device for planting plants in a water-deficient area, the drip irrigation device structurally comprises a water inlet hopper, a lower guide sheet, a water inlet hole, a shielding strip and a water collecting tank, the lower guide sheet is welded on the inner wall of the water inlet hopper, and when water resources in the water-deficient area are deficient and in rainy days, the lower guide sheet is welded on the inner wall of the water inlet hopper through the water inlet hopper and the lower guide sheet mounted on the inner side; rainwater can be guided to flow towards the lower end of the water inlet hopper to enter the water inlet hole, seven shielding strips are arranged on the water inlet hole, it is avoided that impurities such as large impurities, dry branches and fallen leaves doped in the rainwater enter the water collection tank from the water inlet hole to cause blockage, and the rainwater collection and utilization effect is improved; when a water source e
