The invention provides a wood chipping rotor for a wood chipper, which includes a mounting frame, blades are arranged on the outside of the mounting frame, the mounting frame and the blades are combined to form a blast impeller, and the mounting frames are two or more , the included angles between two adjacent mounting frames are the same, the mounting frame is provided with rib partitions, the rib partitions are located between two adjacent mounting frames, and there are several rib partitions. The wood chipping rotor integrates the cutter head, cutter head and blower device into one, and becomes a wood chipping rotor. The intuitive impression can be considered that there is no traditional cutter head setting, which reduces the size of the wood chipper and is easy to move. It is very suitable for home use. The crushed wood rotor adopts an integrated structure, which has high strength, is not easy to deform, and has a long service life. While not reducing the crushing power, it reduces the inertial impact force, low noise, and high safety.
