RATTLING DEVICE Russian patent published in 2013 - IPC B24B31/02 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for hardening part surfaces in free-granulated fluid. Proposed device comprises driven rattler with parts loader and unloader. Said rattler features barrel shape and is composed of sections arranged along rattler axis. From unloader to rattler center, it consists of interconnected one equilateral trapezoid, two identical inequilateral trapezoids and second equilateral trapezoid with height smaller than that of the first one. Their lower bases are equal and smaller than top bases to make a square at faces. Square of every nest section is turned relative to square of previous section through 180 degrees. Note here that every connected section has bottom base square sides equal to those of top base square. From rattler center to unloader, sections are arranged similarly but turned and interconnected in reverse order. Rattler is mounted at the bed by means of air cylinders.

EFFECT: higher efficiency of processing, expanded performances.
