Abstract

The present invention relates to an auto-switching spraying apparatus. The auto-switching spraying apparatus of the present invention includes a pipe body including at least one nozzle branch pipe and a backflow pipe for reversing the flow of water flowing through an upper opening into a branch area and supplying the water to the nozzle branch pipe, a pad disposed at the lower portion of the branch area, and a biasing unit elastically supported by a spring from a pipe body cover, between the pad and the pipe body cover coupled to a lower opening of the pipe body to bias the pad toward the upper opening.

Description

technical field [0001] The present invention relates to an automatic opening and closing spraying device, more particularly to a spraying device that periodically sprays water (including diluted medicine) through a nozzle like a sprinkler in irrigation facilities for crops. Background technique [0002] In the conventional spraying device, after the water supply is cut off, due to the water pressure and the inertia of the water in the water supply pipe, there is a problem that the spray nozzle continues to spray or a small amount of water leaks for a specified time after the water supply is cut off. [0003] Thereby, not only waste water, also be difficult to control the quantitative supply to crops. In particular, when the above-mentioned water leakage phenomenon continues for a long time, it becomes excessive water supply, causing unexpected damage to crops. Contents of the invention [0004] The present invention is proposed to solve the above existing problems. The ma...
