The present invention is to form a wedge to be more specifically, fixed at a lower side of the main body 13 of the floor-mounted sprinklers having a quantity control device that enables easy control the ejection quantity of the ground-mounted sprinklers used by plugging in the ground and the body (1) retrieving pipe that protrudes to one side of (11) and retrieving pipe 11 and the inner ball to get in communication with each other inside the body (1) (12) forming the upper surface, and external light in the center of the body (1) a water outlet within the consultation form a tapered hole 14, and the water outlet hole 14 and the spacing body afloat is hayeoseo form a threaded (17) to the outer surface (1) and a plurality of nozzles in the upper outer side of the adjustment cap (2) 22 are radially formed, and forms a control projection (21) tapered in the lower central portion to form a tightening screw 25, the coupling tube 24 and the inner surface between the coupling tube 24 and the control projections 21, hameuroseo a float separation pipe 23, the protruding distance of the threaded coupling pipe 24 and the control projection (21) between the separation pipe to ensure that water passing groove 26 is formed by a partition (23) main body (1) 17, the upper surface and control cab (2) of the control cab (2) of the pressure screw (25) coupled to the extracting amount of the adjustment depending on the pressure and the cap (2) heading Princess body (1) wall (141) to uitong suhom bottom side and water outlet hole 14 and the outflow water hameuroseo adjust the spacing of the adjustment projection (21) which can be added to the ball grown in the growth of the size of the crops and other plant particularly in the supply amount of the other water, such as a local area mojongpan hameuroseo regulate the water supply to the different types of sprinklers at each other a number of crops grown will have to supply the appropriate amount of water according to the crop.본 고안은 지면에 꽂아서
