Abstract
In an inclined pan feeding apparatus for presenting or discharging particulate material onto a conveyor including a feed hopper, a generally horizontal pan to receive particles from the hopper and deliver the particles in a thin layer to a conveyor belt or roll; the improvement wherein the pan is adjustably inclined downwardly from the hopper to a spillway edge above the belt or roll, the pan being attached to the stationary frame through a front pair of vibration absorbers and a rear pair of vibration absorbers, a rotating motor with eccentric weights is attached to the pan to cause the pan to vibrate generally horizontally, the motor being selectively positioned vertically on the back of the pan, and the front pair of vibration absorbers being selectively positioned at spaced locations along the sides of the pan; and a skirt of flexible plastic fringe hanging closely above and parallel to the spillway edge of the pan.
