Abstract
A trash conveyor has thin upstanding right triangular teeth mounted parallel to their direction of motion. A pivoting deck is positioned over the conveyor and has fixed isosceles-triangular teeth which interdigitate with the teeth on the conveyor. The deck is angled upwardly towards trash infeed end of the conveyor. The deck is suspended by four pivot arms arranged in a rectangular pattern which allow the deck to pivot up and in the direction of the motion of the conveyor. Rows of teeth attached to the deck are offset from previous rows so that the spaces between the teeth on the deck and the teeth on the conveyor varies as the teeth on the conveyor move under the deck. A blade cleaner and conveyor is located beneath the trash conveyor which removes plastic bags from the teeth of the trash conveyor and rolls them into compact shapes to facilitate disposal for recycling.
