Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a wood longitudinal sawing device with good dust extraction effect. Background Art

[0002] The wood processing process usually requires sawing, sanding and other processes. Sawing is a cutting operation performed according to the required size of the wood, including longitudinal sawing and transverse sawing. A lot of sawdust and dust will be generated during the cutting process. The sawdust will splash to the surrounding area, causing harm to the workers, and the dust will affect the health of the workers. Therefore, the current longitudinal sawing devices are usually equipped with protective and dust collection devices, such as the patent with application number "202321305134.5" and the name "A single-piece longitudinal saw machine". The patent is equipped with a dust collection hood, a dust collection box and a dust collector for collecting sawdust and dust, but this type of dust hood and saw table have a large distance in height and width, and the dust extraction effect is poor.
