Patent ID: 8701378

Claim:
A mobile rake device for displacing mown crop, the device comprising a frame with at least one rake tool assembly, wherein the at least one rake tool assembly, when being moved, has a path-shaped working range and comprises two or more rake tools which are provided with rake tines and, in an operative position, are arranged in a sequential, staggered manner in the direction of travel thereby forming a rake tool sequence and wherein each rake tool provides, in the operative position, a path section to achieve the path-shaped working range, wherein the two or more rake tools are provided with a rotor having a rotor point of rotation with a drive for rotation of the rotor around the rotor point of rotation, in the same direction of rotation, and consequently of the rake tines according to associated orbits, in order to displace the mown crop located in the path section in question to one longitudinal side thereof, in a flow of crop, in order to form one final windrow, wherein the at least one rake tool assembly further comprises at least one auxiliary displacing tool that when viewed in a top view in operative position, has a largest horizontal dimension that is smaller than that of any of the rake tools in the rake tool sequence, which the at least one auxiliary displacing tool, when viewed in the direction of travel, is arranged between the rotor points of rotation of two sequential rake tools in the rake tool sequence, and which the at least one auxiliary displacing tool is arranged to throw the crop that has been collected, in a flow of crop or in the form of a pre-windrow, by a first rake tool in the rake tool sequence, across the front of a subsequent rake tool in the rake tool sequence, towards the final windrow to be formed, wherein the at least one auxiliary displacing tool comprises a rotor which is drivable about a rotor centre line and is provided with tines or pins which rotate according to an orbit whose outer diameter is smaller than the outer diameter of the orbit of any of the rake tools in the rake tool sequence.
