Abstract
A material loading and conveying machine has an openended scoop for gathering and containing loose material, and a conveyor for receiving material from the scoop. The open rear end of the scoop abuts a curved backstop plate having a center of curvature on the axis about which the scoop is raised or lowered. In addition, the lower portion of the backstop plate is fixed to the machine, while the upper backstop portion normally abuts the lower portion but is selectively raisable to form a gate which meters the flow of gathered material from the open rear end of the raised scoop onto the conveyor.
Claims8
In a machine for loading and conveying loose material such as sand and the like:
- (a) transport means for supporting and moving the machine on the ground,
- (b) a conveyor mounted on said machine and having a portion disposed adjacent the front of the machine,
- (c) material gathering means mounted to the front of the machine and with said gathering means being pivotable about an axis between a lowered working position and a raised position for discharge of material onto said conveyor,
- (d) and selectively controllable metering means having a portion pivotable about said axis and with said metering means disposed between said material gathering means and said conveyor to thereby limit the discharge of material onto said conveyor.
