Rotary plough with hydraulic cylinders - has pivot operation controlled by relative position of centre of gravity

摘要

A rotary plough, in which the centre of gravity of the plough section can be shifted relatively fore and aft about its rotary plough support mounting, such that the axis of rotation does not pass through the centre of gravity in the operative position, as in the main patent has hydraulic cylinders (D) for the pivoting of the plough body as well cylinders (S) as for sliding the rotary plough section and further cylinders for raising the trailing plough section. A compressed medium pipe (3, 4) is attached to the fittings (10-13) on the cylinders (D, S). The rotating cylinder (D) is so dimensioned that pivoting of the plough occurs only when the centre of gravity is moved to or almost to the rotational axis of the plough section.
