Abstract:

An improved trash separation mechanism at the rear cross-conveyor assembly of a tomato harvester. A frame of the harvester supports a centrally located fruit collecting conveyor for delivering fruit rearwardly to the rear cross-conveyor assembly. A blower directs a strong rearward airstream from adjacently below the rear end of the collecting conveyor across the rear cross-conveyor assembly. A rearwardly rotating roller is mounted adjacently behind the cross-conveyor assembly and moves vegetative and mineral trash away from the cross-conveyor. A slide plate behind the roller may deflect the trash to the ground. A series of resilient fingers depending downwardly from above the roller move in circular vertical patterns to agitate the trash as it collects at the roller to prevent accumulation of the trash upon the roller and to enhance rearward movement thereof upon the roller and deposit of the trash on the ground.
