DE1582227C2 - Mower with several mowing rotors arranged on a support beam - Google Patents

Description

these hollow axles 9 are axles 10 and 11 for support elements 12 and 13, which have a frustoconical Have a shape with a round base. The support elements 12 and 13 are aligned with the axes 10 and 11, respectively rigidly connected, but mounted vertically displaceably together in the hollow axles 9. A central one The height of the support elements 12 and 13 is adjusted according to the exemplary embodiment by turning a non-rotatably arranged on the axis 11 handwheel 14, one below the handwheel 14 on the axis Il also rotatably attached sprocket 15 is set in rotation. From this chain wheel 15 runs horizontally along the support beam 1 a drive chain 16 to a sprocket 17, which is attached to the Axis 10 of the adjacent support element 12 is non-rotatably attached.

With the rotation of the handwheel 14, a uniform lifting takes place via the aforementioned drive means and lowering the axles 10 and 11 in that they have threads in the area of the chain wheels 15 and 17, respectively are equipped that run in mating threads attached to the support arm.
