Description

Technical Field

[0001] The utility model belongs to the technical field of water and fertilizer equipment, in particular to a filtering mechanism for water and fertilizer integrated irrigation equipment. Background Art

[0002] Integrated fertigation technology refers to an advanced fertigation method that integrates irrigation and fertilization. This approach leverages a pressure system or natural terrain drop to add appropriate fertilizers to the water during irrigation. This fertilizer solution, formulated according to soil nutrient content and the crop's specific fertilizer requirements, is mixed with irrigation water and supplied through a controllable piping system. Once the fertilizer and water are mixed, drip irrigation flows through pipes and drippers, evenly, regularly, and quantitatively soaking the root growth areas of the crops, ensuring the soil around the main root systems remains loose and at an appropriate moisture content. Furthermore, water and nutrients are delivered directly and proportionally, based on the specific fertilizer requirements of the crops. Because irrigation water contains high levels of sand and gravel particles, direct injection into integrated fertigation equipment without filtration can easily lead to equipment clogging. Therefore, most integrated fertigation systems are equipped with pre-filtration devices at the water inlet. However, existing filters in integrated fertigation systems are difficult to clean and remove impurities, resulting in poor filtration and a short service life.
