1. Crushing device of plant or other remains, specifically a crushing device (10) designed to collect from the ground branches of trees or other plant and crushed remains for cleaning the area and with eventual reuse of crushed materials such as form of pellets, whose device is of the type driven by a tractor and comprises a rotating cylinder (2) arranged in the longitudinal direction of the device driven from a driving axle of the tractor through conventional transmission mechanisms, transverse to the direction of travel, and provided with means of breakage or cutting of the vegetal remains of the type of hammers or blades (1) that act in combination with an anvil or counter knife element (11) provided with grooves for the passage of the means of breakage during the rotation of the rotating cylinder (2), characterized in that the anvil or counter knife element (11) is capable of pivoting by linking one end with an axis (12) integral with the frame (13) of the device, this pivoting movement being determined by the variations in the speed of rotation detected by an electronic speed control unit of said rotating cylinder (2), at which In effect, the device incorporates a hydraulic or pneumatic cylinder (15) pivotally attached at one end to the frame (13) and pivotally held by the opposite end, by means of the rod (15a) of the hydraulic or pneumatic cylinder, to the end of the anvil or counter knife (11 ) opposite to the linkage to the pivot axis (12).
