Abstract
A watertight belt-drive conveyor system for transporting semi-liquid sludge from semitrailers is disclosed. The conveyor belt is looped around two pulleys located at either end of the trailer and transported by a main drive drum located below the trailer. Adequate frictional pressure is maintained between drum and conveyor belt for driving the conveyor belt under load by a system of four pulleys which force a full-width V-belt into close frictional contact with the outer surface of that portion of the conveyor belt which is wrapped around the main drive drum.
