TILLING CLAW

A tillage tine includes: a base portion (1) that is fitted to a flange (SO) of a rotary tine shaft (S); a vertical blade portion (2) that is formed from a planar plate that extends continuously in a lateral direction from the base portion (1) in side view to a lateral blade curve start portion (G),...

Zusammenfassung:A tillage tine includes: a base portion (1) that is fitted to a flange (SO) of a rotary tine shaft (S); a vertical blade portion (2) that is formed from a planar plate that extends continuously in a lateral direction from the base portion (1) in side view to a lateral blade curve start portion (G), and includes a cutting edge via a step from a lower edge of the base portion (1); and a lateral blade portion (3) that extends continuously with the lateral blade curve start portion (G) as a boundary, is formed by including a width dimension not less than a width dimension of the base portion (1) to a distal end (I) side, is formed by gradually curving to an upper side in side view, and is formed from a curved plate that is curved on one side with the lateral blade curve start portion (G) as the boundary, wherein the lateral blade portion (3) is curved so as to form an obtuse angle in cross-section view orthogonal to the lateral blade curve start portion (G), and the distal end (I) of the lateral blade portion (3) before curving includes a first region (I1) which extends upward from a lower end (I3) of the lateral blade portion (3), and a second region (12) which is continuous from the first region (I1), and is curved or bent in an inward direction to extend to an upper end (I5). Consequently, a tillage tine which suppresses a load fluctuation during driving into soil, reduces tilling vibration or horsepower consumption, and is excellent in a throwing force, reversibility, and a deep tillage performance is provided.
