The invention relates to a rotary processing device for a bamboo pole and belongs to the technical field of bamboo processing. The rotary processing device for the bamboo pole comprises a support body. A bamboo sawing device, a rotatable pipeline container and an engagement support are arranged on the support body, wherein the rotatable pipeline container is arranged behind the bamboo sawing device, and the engagement support is arranged behind the pipeline container and can move on the support body by a certain distance. A sleeve body is arranged outside the pipeline container and fixedly connected with the support body. A rotary structure set is arranged between the pipeline container and the sleeve body. A rotation power source is arranged on the support body and matched with the rotary structure set to make the pipeline container rotate along the axis of the pipeline container. By the adoption of the scheme, rotating force is applied to the bamboo pole when the bamboo pole is sliced, in this way, the bamboo pole can be sliced more easily, internal bamboo filaments can be extracted conveniently, and production efficiency can be improved.
