Description

Technical Field

[0001] The utility model belongs to the technical field of wood processing equipment, and particularly relates to a large-diameter diseased wood disc chipper with adjustable cutting angle. Background Art

[0002] The disc crusher is the most basic equipment in the production of wood-based panels, and is used for producing the basic raw material process wood for papermaking and wood-based panels; for the process wood that needs to be steamed and hot-ground in subsequent processes, the softening effects of different process wood cross-section angles after steaming are very different. The main influencing factor of the process wood cross-section angle is the cutting angle between the log and the cutter head; at the same time, the cutting angle of the process wood also affects the magnitude of the wood cutting force, and a reasonable cutting angle needs to be matched for logs with different mechanical properties.

[0003] The existing disc crushers all install the crushing system on a fixed frame and are mostly manually operated, and the automatic adjustment of the cutting angle cannot be achieved. As a result, the existing disc crushers can only perform undifferentiated cutting and crushing according to the same cutting angle for different batches of logs (the differences between logs are mainly reflected in the diameter and tree species), resulting in the inability to control the shape and size of the cross-section angle of the produced process wood chips. Therefore, there is an urgent need to design a large-diameter diseased wood disc chipper with adjustable cutting angle to solve the above problems existing in the prior art. Summary of the Utility Model

[0004] The utility model aims to solve the problem that the cross-section angle, size and shape of the process wood cut and crushed from different logs cannot be automatically adjusted, and further provides a large-diameter diseased wood disc chipper with adjustable cutting angle.
