[0023] In this embodiment, the blade 3 is made of high-strength alloy material to ensure blade strength and planing and crushing effect.

[0024] In this embodiment, see Figure 5 The feeding mechanism 10 includes a connecting frame 101, and a roller 102 is equidistantly fixedly connected to the interior of the connecting frame 101. Both ends of the roller 102 are fixedly connected to a second driven wheel 103, and the surface of the second driven wheel 103 is connected to the second driving wheel 105 through a second belt transmission. The center of the second driving wheel 105 is fixedly connected to both ends of the double-headed motor 106, and the double-headed motor 106 is fixedly connected to the connecting frame 101. Both ends of the connecting frame 101 are slidably connected to a guide rod 107, and the surface of the guide rod 107 is sleeved with a spring 108, and the two ends of the spring 108 are respectively fixedly connected to the connecting frame 101 and the frame 1; the spring's own elastic force is used to press the roller tightly against the surface of the wood in the feed port, and each double-headed motor on the connecting frame drives the corresponding second driving wheel to rotate, and the second driving wheel drives the second driven wheel to rotate through the second belt, and the second driven wheel drives the roller to rotate, thereby continuously pushing the wood inward mechanically, and then cooperating with the claw knife to achieve the purpose of planing and crushing.
