Abstract

This utility model provides a wood raw material crushing device, including a base, a discharge port connected to the other end of the wood chip channel, and rolling shafts symmetrically arranged on the two side walls of the upper end of the discharge port. An L-shaped movable frame is rotatably mounted on the rolling shaft. The movable frame rotates and engages around the rolling shaft at 90° and can be limited and fixed. When the equipment is working, the wood chips crushed in the crushing box will be discharged into the collection bag hanging on the slot through the wood chip channel and the discharge port. When full, the slot can be squeezed by pressing the sliding pin, which will cause the spring on the telescopic block to press down, thereby causing the slot to disengage from the telescopic block. Due to the weight flip, the movable frame on the slot side will fit against the outer surface of the wood chip channel, automatically closing the internal channel. This achieves semi-automatic opening and closing, speeds up the replacement speed, and prevents the crushed wood pulp and leaf pulp from splashing everywhere, thereby increasing the operation speed and keeping the surrounding area clean.
