Technical Field

The invention relates to a feeding mechanism of a drum chipper.

Background

A drum chipper is a common device for wood chipping, and the working principle of the drum chipper is as follows: the flying knife is driven by the high-speed rotary knife roller, and under the action of the flying knife and the bed knife, the log is cut into sheets, thereby meeting the requirements of artificial boards and paper making.

The existing drum type chipping machine mainly comprises a conveying mechanism, a feeding mechanism and a chipping mechanism, wherein the feeding mechanism is arranged between the conveying mechanism and the chipping mechanism and used for feeding materials (wood, branches and the like needing chipping) into the chipping mechanism, and the materials are chipped through a fly cutter on a cutter roller.

Most of the existing feeding mechanisms are designed in an integrated mode, and stress is mainly concentrated on the front-most compression roller during feeding, so that the front-most compression roller is easy to damage and needs to be replaced frequently.
