When the partition 46 moves to be flush with the support platform 40, it blocks the sawdust in the drawer 55 below, preventing the sawdust from flying around in the drawer 55 due to airflow and affecting material retrieval. After the logs are cut, they fall from the end of the chain 12 and land on the upward-curving side of the support plate 5. When the log segments hit the support plate 5, they vibrate, which helps to shake off the sawdust adhering to the surface. The guide plate 5, with its sloping top, allows the wood segments and sawdust to slide on the support plate 5. When the wood segments and sawdust slide to the discharge port 31, the sawdust slides between several support rods 32. Combined with the extraction by the connecting pipe 56 below, this better separates the sawdust from the wood segments. When the exhaust fan 35 starts, the exhaust pipe 37 exhausts air outwards. The air exhausted from the exhaust pipe 37 flows along the exhaust pipe 38, is pressurized by the nozzle 39, and is then sprayed out to clean the saw teeth on the saw blade 16, preventing sawdust from getting stuck on the saw teeth and increasing friction with the log. Friction, and the blowing action helps the saw blade 16 cool down quickly, preventing it from overheating and scorching the cutting end of the log. As the partition 46 moves left and right, it also moves the support frame 52 left and right, causing the support frame 52 and the top block 53 to move left and right. When the top block 53 moves to the left, it presses against the inclined surface of the top of the protrusion 51. Under the pressure of the top block 53, the protrusion 51 moves downward, pressing the third spring 50. When the top block 53 moves to the point where it disengages from the protrusion 51, under the action of the third spring 50, the protrusion 51 moves towards... The top block 53 moves upward and then resets. When it moves to the right, it presses against the protrusion 51, pushing the protrusion 51 and the filter plate 44 to move to the right together, compressing the second spring 43. Once the second spring 43 is compressed, the top block 53 continues to press, causing the protrusion 51 to move downward. After the top block 53 passes through the protrusion 51, the filter plate 44 moves back and vibrates under the action of the second spring 43. This facilitates the shaking off of sawdust adhering to the filter plate 44, preventing the sawdust from clogging the filter plate 44 and affecting the filtration effect.
