Description

Technical Field

[0001] The utility model specifically relates to a sawdust processing device for wood processing, belonging to the technical field of sawdust processing devices. Background Art

[0002] When processing wood, it is necessary to cut the wood into various styles. When cutting wood, a large amount of wood chips will be generated. Therefore, the wood chips need to be processed. Since the wood chips generated when cutting wood are of different sizes, it is very inconvenient for workers to collect and process them. Usually, negative pressure suction is used to absorb the wood chips for processing. However, wood chips of different sizes will easily block the air inlet, resulting in a gradual decrease in the absorption efficiency. For this reason, Chinese Patent Publication No.: CN114872150A discloses a wood chip processing device for wood processing. When the wood chips are sucked by starting the negative pressure fan, the cleaning plate can scrape the outer wall of the filter plate, which can effectively prevent wood chips of different sizes from adhering to the filter plate to cause blockage, thereby improving the filtering and blocking efficiency of the filter plate. However, the scraped wood chips are prone to cause local accumulation, and the wood chips cannot be processed and reused. Utility Model Content
