Chopping rotor for chopping wood, has adjustment device to adjust cutting depth of chopper into chopping object by direct/indirect modification of variable radius of rotor body in region, which is circulated by chopper in rotation direction

摘要

The rotor has choppers (1) that are projected above a fixed outer circumference (13) of a rotor body (2) without changing the position of the chopper. An adjustment device (14) is provided for variable or stepless or stepwise adjustment of cutting depth (15) of the chopper into a chopping object. The cutting depth of the chopper into the object is adjusted by direct or indirect or stepless or stepwise modification of variable radius (16) of the rotor body in a region, which is circulated directly or indirectly by the chopper in a rotation direction.
