The present invention provides a drum for a shot blasting apparatus that uniformly treats the works to be treated by increasing the level of agitation of the works that are buried at the bottom of the drum, and, further, suppressing the traces of collisions on the works, which traces are caused by the works colliding with each other. The drum comprises a hollow middle part, a lower-half part having the shape of a truncated cone, having a closed bottom, and having a projecting part for agitating that is connected to both the lower-half part and the middle part, and that agitates the works, wherein the projecting part for agitating has at least two surfaces, one being the surface for picking-up the works and the other being the surface for having the works slide down. The present invention also provides the shot blasting apparatus using the drum.

Drum for a shot blasting apparatus and shot blasting apparatus

To provide a novel shot-blasting machine to eliminate a dead space for a cover that shuts an opening for feeding and taking out works and to open and close the cover by moving a rotary drum around an axis. The machine has a cabinet, a rotary drumhaving holes, and a centrifugal shooting machine. The rotary drummoves, within the cabinet, around an axis through the positions for feeding, processing, and taking out the works. The cabinetcomprises a coverfor shutting an openingfor feeding and taking out the works. It has a wallfor sealing the side of the opening. The coveris integrated with the rotary drumto move around the axis. It has wallsthat fit the wallfor sealing. Lip sealsseal the gap between the wallsof the coverand the wallfor sealing.
