This invention discloses a
wood cutting device, belonging to the field of
wood processing technology. The device includes a base, a power drive unit, and a
wood cutting component. The power drive unit drives a rotating shaft to rotate a serrated rotary cutter. The
wood cutting component includes a spiral cutter and a serrated rotary cutter. The spiral cutter and the serrated rotary cutter are coaxially arranged, both with a spiral structure at their front ends. The spiral cutter has a
cutting edge on its end face and a serrated end; the serrated rotary cutter has serrations on its end face. When the wood enters the device, the spiral cutter quickly cuts the wood using a rotary
cutting method, avoiding
sawdust flying. When encountering hard areas such as tillers, nodules, or
callus tissue, the spiral cutter moves backward under the action of a spring, and the serrated rotary cutter automatically participates in the
cutting, ensuring reliable cutting. Compared with traditional sawing methods, this device has high cutting efficiency and a clean
cut, enabling the wood to be directly processed into
fireplace fuel, cutting substrate, or
mushroom cultivation material.
