Abstract

Multiple conveyor cleaning assemblies are mounted on a section of the support rail of a large chain conveyor, with each assembly including one or more long-bristled brushes for cleaning the chain as it moves through that rail section. The side cleaners are mounted on supports which are readily swingable between their chain-engaging cleaning positions and retracted positions wherein the brushes are withdrawn from the chain and related structures for ready removal and replacement of the cleaning heads. A single latch bolt holds each of these side cleaners in the cleaning position. Further, each cleaning head is engaged on its respective support by simple slide engagement in the direction of movement of the contacted conveyor chain whereby the frictional engagement of the chain holds the cleaner in its cleaning position on the support without further attachment between the cleaning head and its support. A top cleaner includes three brushes mounted on one holder such that their bristle axes converge for cleaning the upward projecting top portions of the chain components. Multiple provisions are made for adjusting each of the brushes in its operative position.
