WEEDER FOR PADDY FIELD

摘要

PROBLEM TO BE SOLVED: To carry out excellent weeding of intrarow spacing by a weeder for a paddy field in which a weeding apparatus comprising an interrow space weeding mechanism acting between planted seedling rows and an intrarow spacing weeding mechanism acting between intrarow spacing parts in a planted seedling row is liftably connected to the rear part of a sulky traveling machine body. SOLUTION: The interrow space weeding mechanism is constituted by arranging a plurality of weeding rotors 31 to be rotated and driven around the centers of traversal axes at an equal speed in parallel in the transverse direction so that the weeding rotors act between seedling rows. The rotation phases of the each weeding rotor 31 are set so that each of the weeding rotors 31 is equipped with weeding tines 54 at a fixed pitch in the circumferential direction, the rotation phases of the weeding tines 54 of a plurality of the weeding rotors 31 arranged in parallel in the transverse direction driven into the surface of a paddy field are differentiated and the weeding tines are symmetrically driven into the surface of a paddy field.
