In a rake system, a reamer element is attached to a reamer arm, which is movable backward and forward. A pivot axle of the reamer arm is formed on the distal end of a control arm, which is pivotable around a further pivot axle. During forward movement of the reamer arm, the reamer element pushes raked material collected by the rake to a discharge edge at the upper end of the rake. During backward movement of the reamer arm, the control arm is lifted, and the reamer element is moved back at a distance from the rake. |

1. A rake system with a rake, to be arranged at an angle in a channel, and a reamer, comprising:
a reamer arm for conveying raked material to a discharge edge, a pivot axle, above the rake, around which the reamer arm is suspended in a swinging manner, a first actuating device by which the reamer arm is displaceable in backward and forward movements along the rake, and a reamer element at a distal end of the reamer arm which faces the rake, wherein the reamer element is caused to run on the rake during the forward movement and to run at a distance from the rake during the backward movement, wherein the reamer arm is suspended on a distal end of a control arm, which is pivotably mounted on its proximal end, wherein, for swiveling the control arm, a second actuating device at least at times engages at the control arm, wherein the first and second actuating devices are coupled with one another such that movements of the control arm and the reamer arm are synchronized, and wherein the second actuating device does not engage with the control arm during the forward movement of the reamer arm. |
