| 摘要 | Disclosed is a mobile shredding machine for shredding vehicle tires. The machine has a rotating flywheel with a pair of projecting radially extending blades on one face thereof. The flywheel is mounted on a truck chassis and driven by an electric motor powered by a motor generator. The electric motor has controls so that the speed of rotation of the flywheel can be regulated. The flywheel is mounted in a frame on the truck chassis which supports a fixed blade in shearing relationship with said flywheel blades. Tires are fed to the flywheel by a feed conveyor which flattens the tire carcasses and feeds them to the blades in this condition. The flywheel is surrounded by a housing which fits with close tolerances the periphery of the wheel and the rotating blades on the face surface, so that shreds are carried in rotation with the flywheel after they are cut onto a shred discharge conveyor at the side of the truck chassis which carries them to a shred pile or into a hauling truck. | ||||||
