At present, the sprinkler equipment in agriculture is usually installed directly in the farming area for the convenience of use, and there is no need to install and arrange pipelines every time. However, since the sprinkler is usually in an exposed state, in an agricultural environment, soil particles and silt, insects, debris, garbage and fallen leaves can easily enter the sprinkler, eventually clogging the sprinkler, affecting the subsequent use of the sprinkler. In addition, the spraying range of the sprinkler is not easy to adjust, and the flexibility is insufficient, which affects the normal sprinkler irrigation work. Utility Model Content
