METHOD AND APPARATUS FOR CLEANING USED BRICKS

摘要

A machine for cleaning mortar from used bricks and the like comprising a hopper (46) for moving bricks onto a feeding position at one end of a channel, a ram (32) for pushing one brick after another, each brick pushing a series of preceding bricks, from the feeding position along the channel and through gangs (62) of interleaved spur gear assemblies (112) which crumble the brick mortar and thence through scrapers (172) which remove the crumbled mortar from the bricks. The spur gear assemblies are biased to accommodate different sizes of bricks and the hopper moves the bricks into feeding position one at a time.
