[problem] in the field, such as large-sized machine is not put, compost loading the compost in the storage location Go to scatter location, to provide a one-wheel fertilizer application to seeded scatter streak plated weight loss seeded or point of a suitable amount of compost to crops. A one right and two of the impeller on the left side 3 of the wheel 1 of the axle 4 and, with the interrupter 2 right and left tell when needed the rotation of the wheel 1 in each of the impeller 3, manipulating these interrupter 2, the interrupter operating lever 6 of the right and left, to inhibit the rotation of the impeller 3 half on two of the impeller 3 without and, the interval without that compost leaks has been to place a hopper 5 for loading two compost covering respectively, by rotating the impeller 3 via the interrupter 2 by the force of rotation of the wheel 1, the compost was loaded into the hopper 5 is impeller 3 When rotated, it was drained successively to the outside of the hopper 5, and spraying the compost in the field and dropped the field.BACKGROUND 2【課題】大型の機械が入れないような圃場で、保管場所に有る堆肥を積み込み堆肥散布場所まで移動して、作物に適した量の堆肥の筋蒔き減量撒き又は点撒き散布する1輪堆肥散布機を提供する。【解決手段】1つの車輪1の車軸4の右側と左側に2つの羽根車3及び、車輪1の回転を必要時にそれぞれの羽根車3に伝える右及び左の断続器2と、これらの断続器2を操作する、右及び左の断続器操作レバー6と、2つの羽根車3の上半分を羽根車3の回転を阻害する事無く且つ、堆肥が漏れ出す事のない間隔を有してそれぞれを覆う2つの堆肥を積み込むホッパー5を配置し、車輪1の回転の力で断続器2を介し羽根車3を回転させて、ホッパー5内に積み込まれた堆肥を羽根車3が回転した際に、順次ホッパー5の外に排出させて、圃場に落として堆肥を圃場に散布する。【選択図】図2
