Abstract
A conveyor for handling free-flowing material such as grain products or the like. The conveyor characterized by having a bottom liner and side liners. The liners are replaceable and greatly increase the wear life of a conveyor housing. The liners also reduce drag and wear on an endless chain and flights attached thereto while reducing horsepower requirements in the conveying of the material.
Claims8
A conveyor for handling free-flowing material such as grain products or the like, the conveyor comprising:
- an elongated conveyor housing having a bottom portion and side portions;
- and endless chain disposed above the bottom portion of said housing;
- drive means for engaging and driving said chain thereon, said drive means attached to the side portions of said conveyor housing;
- a plurality of conveyor bottom liners positioned on top of the bottom portion of said conveyor housing, said endless chain and said flights disposed on top of said bottom liners and riding thereon, said bottom liners laid end to end with a space therebetween sufficient to allow the liners to expand lengthwise and a space between the sides of said bottom liners and the side portion of said housing to allow said bottom liners to expand laterally;
- first attachment means for securing said bottom liners to the top of the bottom portion of said conveyor housing and providing means for expansion and contraction of said bottom liners on the bottom portion of said housing;
- and
- V-shaped flights attached to said endless chain, the width of the flights greater than the space between the ends of said bottom liners.
