Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a drum chipper for wood processing with adjustable blade angle. Background Technology

[0002] In the wood processing industry, efficient wood pretreatment equipment plays a crucial role in improving production efficiency and product quality. Drum chippers, as a widely used wood processing equipment, have become the first choice for many wood processing plants due to their unique working principle and excellent performance. A drum chipper mainly consists of a drum roller, fly cutters, a bottom cutter, a feeding device, and a discharging device. During operation, wood is fed into the machine through the feeding device, where several fly cutters are mounted on the high-speed rotating drum roller. When the wood comes into contact with the fly cutters, it is quickly chipped into wood chips of a certain size under the cutting action of the fly cutters. The bottom cutter assists in the cutting process, ensuring that the quality and size of the wood chips are uniform. The chipped wood chips are discharged from the machine through the discharging device and enter subsequent processing steps.

[0003] In response, Chinese patent application number CN201921419644.9 discloses a drum chipper for anti-clogging particleboard production. Its structure includes a discharge port, an anti-clogging device, control buttons, a control box, a hydraulic cylinder, a base, a conveyor belt, a roller, a feeding roller, and a machine body. The discharge port is located at the right end of the anti-clogging device. A set of control buttons is installed at the front of the control box. The front of the anti-clogging device is in contact with the rear surface of the control box.
