Abstract
A wood crusher having a crushing apparatus includes a crushing rotor for crushing target wood to be crushed, a second screen detachably mounted on the outer peripheral side of the crushing apparatus and a screen support member disposed on the outer peripheral side of the second screen and holding the second screen in a position on the outer peripheral side of the crushing apparatus. A link mechanism is coupled to the screen support member, and a hydraulic cylinder is coupled to the link mechanism to advance and retract the screen support member relative to the crushing apparatus with extension and contraction thereof. Time and labor required for work of replacing the sieve member can be greatly reduced as a result.
