  • Publication number: 20110067780
    Abstract: A apparatus uses a flexible belt material stretched between two roller bearings to move a granular material such as sand from near ground level to a height sufficient for filling storage receptacles such as sand bags by gravity induced flow. The motive power for the apparatus may be a drive wheel which rests on the top surface of the conveyer belt over the lower roller bearing. The drive wheel is supported by the lower roller bearing and a second support bearing. The rotational motion of the drive wheel is translated to linear motion of the conveyer belt by friction between the drive wheel and flexible belt material. The drive wheel is held in position by gravity and may be quickly removed from the apparatus so that it can be relocated. The distance between the rollers may be changed to accommodate different diameter drive wheels or a change in the vertical angle of the conveyer belt.
