Double Disc Coulter

摘要

A double disc coulter 1 has two disc coulters 2 angled to each other to form a V shape that are rotatable on hollow axle stubs 3 by means of bearing units 18. One hollow axle stub 3 is arranged with a flange face 5 facing the coulter bar 4 at an angle to the vertical plane of the rotation axis of the hollow axle stubs. At the same time, the hollow axle stub 3 determines the angular position of the plane 13 that intersects in the rotation axis 6 and in an axis 7 vertical to the flange face 8, 9 of the coulter bar 4.

1. Double disc coulter (1) with two disc coulters (2) angled towards each other to form a V shape, which are pivotable on hollow axle stubs (3) by means of bearing units (18) and are fixed pretensioned with the hollow axle stubs (3) and their flange faces (5) against the flange faces (8, 9) of a coulter bar (4),
characterised in that the hollow axle stub (3) has a flange face (5) facing the coulter bar (4) that is arranged at angle to the vertical plane (24) of the rotation axis (6) of the hollow axle stubs (3) and that the hollow axle stub (3) determines the angular position of a plane (13) that intersects in the rotation axis (6) and an axis (7) vertical to the flange face (8, 9) of the coulter bar (4).
