Abstract

Separable rake teeth, comprising rake teeth (1) and rake teeth position-fixing seats (2). The rake tooth position-fixing seats (2) are connected to a rotary drum (3), and are arranged in intervals along the annular surface of the rotary drum (3), the rake teeth (1) being moveably connected to the rake tooth position-fixing seats (2). The long-distance deformation and damage caused by the rake teeth on the fixed parts in rolling feed-raking loader are solved. The distance between a fixed part and the top of a rake tooth is significantly decreased, and the overall weight is reduced, thereby making rake teeth replacement easier.
