ABSTRACT:
A stationary grid of crossed blade members is provided and force structure is movable toward and away from one side of the grid and operative to engage a farm commodity such as an onion and gradually move the onion toward the grid. Knife structure is supported relative to the grid for repeating movement in a plane generally paralleling and slightly spaced outward of the other side of the grid and across the latter. Drive structure is operatively connected to the knife structure for repeated movement of the latter across the grid at a speed proportional to the speed of movement of the force structure toward the grid. The force structure includes a plate paralleling the grid and spaced outwardly of the aforementioned one side thereof. The plate includes a plurality of blunted pins projecting outward therefrom toward the grid and projectable into the spaces defined between adjacent portions of the crossed blade members of the grid. An extraction plate having a plurality of openings formed therethrough is mounted on the pins for frictionally resisted sliding movement therealong and the extraction plate is engageable with the grid for shifting of the extraction plate toward the base ends of the pins. In addition the extraction plate includes abutment pins which project through openings provided therefor in the force structure and whose free ends are engageable with abutment surface portions to shift the extraction plate toward the free ends of the blunted pins upon movement of the force plate to a predetermined position away from the grid.
