Machine for lifting onions or other root-crops, in particular of the type towed by farm-tractor.

摘要

The machine described herein comprises a vibrating channel (5) disposed rearward of a blade (3) and designed to carry along a crop whilst shaking it free of soil, the work-surface of said channel consisting of a number of rods (21) disposed within vertical and longitudinal planes and spaced sufficiently close together to create a surface having the semblance of a grid. The rods (21) are subject to a special alternating motion imparted at low amplitude and high frequency which brings about both efficient seperation of soil from the crop and orderly and steady progress of the latter along the channel itself (5). A chute (16) located to the rear of said channel (5) provides for the crop's being re-deposited on the ground continuously and systematically.
