[0002] Wood has numerous uses, and crushed waste wood also has a wide range of applications. Crushed wood can be used as an energy-saving building material, an energy source, and can suppress pollution and reduce waste accumulation. Therefore, waste wood is often crushed for reuse. Wood crushing requires a wood crusher, which primarily crushes wood and other items, maximizing their usefulness while minimizing environmental pollution. It is a relatively quick, ideal, and affordable wood crushing device. Currently available wood crushers typically consist of a conveyor and crushing mechanism. Loading is performed by a worker operating a mechanical device such as a grabber. Due to the limited capacity of the conveyor belt, workers are required to frequently and continuously load small amounts of material to ensure stable operation. This requires continuous and uninterrupted work, increasing the workload. Furthermore, existing systems can cause the conveyor belt to sag under the pressure of wood over time, leading to slippage and low efficiency during conveying. This requires replacing the conveyor belt, which is difficult. Therefore, there is a need for a wood crushing device that can accommodate large amounts of material at once, eliminates the need for continuous work, and allows for easy adjustment when the conveyor belt sags.
