Abstract
A rake includes a draw bar, anchored at the back to a cross bar ending with hinges having a rotation axis that is parallel to the draw bar. The cross bar is connected through the hinges with two arms, each one appropriate for sustaining the supporting elements of a group of ray rakes. The rake also includes supporting and regulating members for raising the cross bar from the ground and therefore the group of ray rakes, and actuator elements, independent from each other, through which the operator guides the movements of the supporting elements and those of the supporting and regulating members for raising the cross bar from the ground.
Claims9
A towed ray rake with independent adjustments comprising:
- a draw bar (1) connected at the back with a cross bar (3) for carrying a support for ray rake groups (4) that rotate on a plane that is nearly perpendicular to the axis of said draw bar (1);
- supporting and regulating means (5) for raising the cross bar (3) from the ground;
- two actuators that operate independently from each other, one of said actuators rotating the ray rake groups on the plane that is nearly perpendicular to the axis of the draw bar and another of said actuators raising the cross bar (3) from the ground.
A towed ray rake comprising:
- a draw bar attached to a cross bar, said cross bar having hinged ends for carrying ray rake groups;
- a rotatable frame carrying wheels for the towed ray rake at a rear end of said frame, said frame being hingedly connected to said cross bar at a front end of said frame;
- a first actuator connecting said rear end of said frame to said cross bar for rotating said cross bar about said rear end of said frame;
- and
- a pair of second actuators that each are connected at one end to said cross bar adjacent to said draw bar and at another end to a respective one of said hinged ends for rotating said hinged ends, said first actuator being independent from said pair of second actuators so that said hinged ends rotate independently of rotation of said cross bar.
