Description

Technical Field

[0001] The utility model belongs to the technical field of drip irrigation devices, and more specifically, particularly relates to a water-saving drip irrigation device. Background Art

[0002] Drip irrigation can deliver water and nutrients directly to the roots of crops in the form of drips, thereby achieving the purpose of water and fertilizer saving and precise irrigation. Since potatoes are prone to nutrient deficiencies in the later stages of growth and require foliar fertilization, most potatoes are irrigated using an integrated system of drip irrigation and micro-spraying water and fertilizer. When foliar fertilization is required, fertilizer is sprayed on potato leaves through micro-sprinklers.

[0003] For example, CN220916084U discloses a water-saving drip irrigation device for potato planting, comprising a drip irrigation component; a mixing component; the mixing component comprises a fixed pipe placed inside the drip irrigation pipe, a water inlet opened at both sides of the upper end of the fixed pipe, a water outlet opened at both sides of the lower end of the fixed pipe, a fixed rod connected to the bottom end of the fixed pipe, a rotating shaft connected to the upper end of the fixed rod, a supporting disc connected to the outer surface of the rotating shaft, and a rotating motor connected to the upper end of the supporting disc; the utility model solves the problem that in the existing potato planting, when fertilization is required by drip irrigation, the fertilizer needs to be mixed with water in advance, and the fertilizer and water are flowed into the drip irrigation pipe through the water inlet pipe, so that the fertilizer and water are discharged into the root position of the potato, but when the fertilizer is inside the drip irrigation pipe, it will slowly settle due to the increase of time, resulting in uneven fertilization, and the fertilizer may cause blockage of the drip irrigation pipe.

[0004] Based on the above, in order to ensure that the fertilizer can be sprayed on the leaves, most of the existing drip irrigation devices are set relatively high, resulting in a long time for the fertilizer to fall from the air to the leaves. When potatoes are sprayed in windy weather, the fertilizer is easily blown away by the wind during the falling process, resulting in fertilizer waste. It is also easy to cause uneven fertilizer spraying, affecting the fertilization effect on potatoes. Utility Model Content
