The present invention relates to an agricultural sprinkler. In the configuration, the inner fixed tube (1) and the outer fixed tube (2) surrounding the inner fixed tube (1) is composed of an outer fixed tube (2), wherein the inner fixed tube (1) is a coupling tube (11) at the bottom ) Is provided, the upper end is provided with a rotating shaft portion 13 and a male screw portion equipped with one or more O-rings 12, inside the top is blocked, and one side has a configuration in which a discharge hole 14 is inclined in an oblique direction, The outer rotating tube body 2 is formed with a hole 21 in which the rotating shaft portion 13 is coupled to the upper center portion, and nozzles 22 are provided on both sides of the outer circumferential surface. Internal fixed tube (1) A space portion (25) is formed at predetermined intervals between the outer circumferential surface and the inner circumferential surface of the outer rotating tube, and a plurality of rotation inducing protrusions are formed on the inner wall underneath the inner fixed tube (1) corresponding to the discharge hole (14) ( 24), when assembling the outer rotating tube (2) to the inner fixed tube (1), first assemble the outer rotating tube (2) with the compression spring (3) fitted to the rotating tube (2), It is characterized in that the external rotation tube (2) is assembled by fastening the cap nut (4) to the male screw portion protruding to the top. In the present invention configured as described above, as the water supplied through the water supply pipe 5 is discharged in the oblique direction through the discharge hole 14, it acts on the rotation inducing projection 24, so that the external rotating tube 2 naturally rotates in one direction. In this case, the water pressure in the space portion 25 is sprayed evenly from a close to a distant place through a pair of nozzles 22, so the spraying range is very uniform, so that even growth, productivity, and quality of the crops can be achieved.
