Tool e.g. shovel, support for cultivator, has pneumatic actuator inserted between arm and extension of other arm, where extension is arranged opposite to rotation axis with respect to other rotation axis

摘要

The support has an arm (22) with an end articulated along a rotation axis (24) to a distal end of an arm (20), and an arm (26) at which a tool (16) e.g. shovel, is connected. An end of the arm (26) is articulated along a rotation axis (28) to another end of the arm (22), where axis (28) is parallel to the axis (24). A pneumatic actuator (54) is inserted between the arm (20) and an extension (62) of the arm (22), where the extension of the arm is arranged opposite to the axis (28) with respect to the axis (24).
