The invention relates to a chip accelerator wheel (14) for use in a wood chipper (1) and provided with a number of accelerator blades (19). Each accelerator blade comprises two opposite end sections (23a, 23b), each of which having a sliding surface (24) on its upper side. The sliding surface (24) of each one of the two end sections(23a, 23b)of each accelerator blade is inclined outwards away from the sliding surface of the opposite end section of the accelerator blade at such an angle of inclination that wood chips hit by the sliding surface (24) during the rotation of the chip accelerator wheel are made to slide downwards along the sliding surface towards a middle part of the accelerator blade (19) before being thrown forwards by the accelerator blade. The invention also relates to a wood chipper provided with such a chip accelerator wheel. |
