PROBLEM TO BE SOLVED: To provide an agricultural material feeder which is enabled to perform a let-off quantity adjustment quickly although the feeder drives a let-off rotor by transmitting driving force of a rocking driver to a rocking operator through a push-pull input lever, a relay rocker and a push-pull output lever.SOLUTION: An agricultural material feeder comprises: let-off quantity adjusting means 83 for moving and adjusting a rocking fulcrum 62 of a relay rocker 52 and holds the same at an adjustment position. The let-off quantity adjusting means 83 changes the intermediate rocker 52 into a state, in which the intermediate rocker 52 is rocked in a direction along a push-pull output lever 66, and a state, in which the same is rocked in a direction along the push-pull output lever 66, so that a let-off quantity by a let-off rotor may be changed and adjusted.COPYRIGHT: (C)2014,JPO&INPIT【課題】揺動駆動体の駆動力を押引き入力杆、中継揺動体、押引き出力杆を介して揺動操作体に伝達することで繰出し回転体を駆動する農用資材供給装置でありながら、繰出し量調節を迅速に行なえるようにする。【解決手段】中継揺動体52の揺動支点62を移動調節して調節位置に保持する繰出し量調節手段83を設けてある。繰出し量調節手段83は、中継揺動体52を押引き出力杆66に沿った方向に揺動する状態と押引き出力杆66に交差した方向に揺動する状態とに変更して、繰出し回転体による繰出し量を変更調節する。【選択図】図7
