摘要：
A vertical rotary post in a silo is formed with a transverse passage across and into which a stop sleeve is fixed. A chain, for loosening compacted material in the silo, extends freely through the passage. The chain has a ring, at one end, which extends into the passage but is stopped by the stop sleeve.
