Cleated belt tube conveyor with improved tracking and capacity

A tube conveyor system for conveying grains and other particulate materials, the tube conveyor system comprising:

• a. an endless belt having an outer surface, a longitudinal axis, a transverse axis, a flat configuration, and a conformed configuration;
• b. a plurality of longitudinally spaced-apart cleat rows extending from the outer surface of the endless belt and along a transverse axis of the endless belt, each of the longitudinally spaced-apart cleat rows comprising:
• i. a central cleat member having a top portion;
• ii. a peripheral cleat member having:
• 1. a central portion,
• 2. a peripheral portion, and
• 3. a slanted top portion between the central portion and the peripheral portion;
• c. in the flat configuration, the central portion of the peripheral cleat member is taller than the peripheral portion of the peripheral cleat member;
• and
• d. in the conformed configuration, the endless belt conforms to a curvilinear cross section of the tube conveyor system thereby conforming a cleat row to a non-overlapping cleat wall wherein the slanted top portion is perpendicular to a vertical axis of the tube conveyor system.
