Field of the Invention The present invention relates to an agricultural spraying apparatus for spraying and supplying a spraying liquid such as water or agricultural chemicals supplied to crops mainly in a greenhouse and more particularly to a spraying apparatus for spraying a spraying liquid upward, And the spraying device can be adjusted to spray in the downward direction, thereby improving the use efficiency.

Generally, various methods for spraying pesticides or water on crops grown in orchards, vinyl houses, and plains have been proposed and used.

One of them is manually pumping a sprayed liquid onto the back of the tank while moving on foot every place where the liquid is to be sprayed, thereby spraying the pesticide through the nozzle.

However, the method in which the user manually injects the sprayed liquid into the crops manually requires a large amount of labor, and has a problem of infringing the safety of the user, such as pesticide poisoning.

In recent years, a spraying apparatus having a supply pipe for supplying a spray liquid such as water or pesticide, and a plurality of spray nozzles connected to the supply pipe at a predetermined interval and fixedly mounted by a fixture has been proposed and widely used. It is mainly applied to growing crops in greenhouses.

The injection nozzle is mainly composed of a cylindrical connection pipe in which the supply pipe is inserted and a connection portion in which an insertion hole is formed in the upper side and the lower side, respectively, and in which a liquid inflow hole is perforated; And a nozzle cap screwed to an end of the spray tube.
