ABSTRACT:
The specification discloses an apparatus for harvesting vegetables such as onions, including a topping plenum and a root cutting bed. Onions are removed from the ground by a self-adjusting digger conveyor which conveys them to an elevator conveyor. The elevator conveyor rises steeply over the large diameter, wide tires which convey the apparatus through the field. From thence the onions are conveyed beneath a vacuum plenum through a first air flow zone which is baffled so that the air flow is just sufficient to raise the tops of the onions off the conveyor and then through a second air flow zone where the onions are actually lifted off the conveyor and into registry with a registering and cutting means which cuts the tops off the onions. From thence they drop onto a root cutting bed which removes the roots of the onions and conveys them to a bulk loading conveyor. Dirt and offal drawn into the vacuum fan are conveyed out of the vacuum fan housing by a continuous conveyor system.
