The present invention relates to a grain-seeding apparatus, and more particularly, to a grain-seeding apparatus that uses a supply unit that selectively discharges grains one by one by rotation of a wheel, thereby preventing grains from being excessively concentrated at one point of sowing, The present invention relates to a grain seeding apparatus capable of quickly, easily and conveniently adjusting the distance between seedings by installing and using a gear box for the seeds. The apparatus for seeding according to the present invention comprises: a housing (100) having a discharge port (120) formed by cutting a part of a lower side edge thereof； a cam surface (130) A supply unit 200 located inside the housing 100 for discharging the grains one by one through the outlet 120； A storage unit 300 fastened and fixed to one side of the housing 100 and storing grain therein； And a wheel 500 is axially coupled to the other side of the housing 100 so that the rotation of the wheel 500 causes the supply unit 200 to rotate Wherein the supply unit 200 is formed in a disc shape and is fastened and fixed to a first rotation shaft 410 provided in the gear box 400, 410； A supporting part 220 formed at a portion of the through hole 211 formed in the rotating plate 210 and allowing the grain 600 stored in the storing part 300 to be seated one by one when the rotating plate 210 is rotated, ； And a pressing part 230 for pressing and fixing the cereal 600 seated on the supporting part 220. The pressing part 230 is formed in the form of a thin plate, A pressing plate (231) for pressing the grain placed on one side of the tray； And a moving part 232 formed to penetrate through the through hole 211 and fastened to the pressing plate 231 and moving the pressing plate 231.본 발명은 곡물 파종장치에 관한 것으로서, 더욱 상세하게는 바퀴의 회전에 의해 곡물을 하나씩 선별하여 배출하는 공급부를 사용함으로써, 파종 시 곡물이 한곳으로 과도하게 집중되는 것을 방지하고, 특히, 기어비를 조절할 수 있도록 기어박스를 설치하여 사용함으로써, 파종 간의 거리를 빠르고 쉽고 편리하게 조절할 수 있도록 하는 곡물 파종장치에 관한 것이다.본 발명에 따른 곡물 파종장치는 하측
