Abstract
In order to enable the setting of the inlet funnel of a wood chipper to different positions for adaptation to prevailing operating conditions including the type of material to be chipped, it is proposed in accordance with the invention that cooperating bearing means be arranged on the chipper rotor housing of the wood chipper and on the frame supporting the chipper rotor housing so that the chipper rotor housing and the inlet funnel are pivotal around the axis of rotation of the chipper rotor.
Claims17
A wood chipper comprising a chipper rotor housing supported by a frame, and a chipper rotor rotatably journaled therein, said chipper rotor housing having inlet means for feeding material intended for chipping into the chipper rotor and outlet means for discharging wood chips produced by the chipper rotor, said chipper rotor housing and said frame including cooperating bearing means in the form of cooperating, arc-shaped support and guide means having radii that have a common center in the axis of rotation of the chipper rotor, the chipper rotor housing being, by means of said bearing means, pivotally arranged on the frame for pivoting around the axis of rotation of the chipper rotor and setting of said inlet means in different operating positions for adaptation to different operating conditions.
A wood chipper comprising a chipper rotor housing supported by a frame, and a chipper rotor rotatably journaled therein, said chipper rotor housing having inlet means for feeding material intended for chipping into the chipper rotor and outlet means for discharging wood chips produced by the chipper rotor, said chipper rotor housing and said frame including cooperating bearing means, the chipper rotor housing being, by means of said bearing means, pivotally arranged on the frame for pivoting around the axis of rotation of the chipper rotor and setting of said inlet means in different operating positions for adaptation to different operating conditions, and a fan housing with inlet and outlet means, said fan housing being stationarily arranged in relation to the chipper rotor housing so that the fan housing and the outlet means thereof are free from the effect of a pivot movement of the chipper rotor housing.
