ABSTRACT:
A harvesting machine for root row crops, such as onions, radishes, parsley, turnips, turnip greens, carrots, and the like wherein the individual plants have root bodies within the soil and tops above the ground. The harvesting machine has at least one harvesting wheel mounted on a vehicle for movement along a plant row and provided about its perimeter with a pair of annular, axially confronting plant top gripping means which open and close locally as the wheel turns, in a manner such that the gripping means open within a plant receiving zone within the bottom of the wheel to receive between the gripping means the tops of the plants in the plant row being harvested, and the gripping means then close to grip the intervening plant tops, extract the plants from the ground, and transport the extracted plants upwardly through a transfer zone to an upper plant releasing zone, where the gripping means reopen to release the plants from the wheel. Plant treatment means may be arranged about the wheel perimeter for washing, trimming, brushing, and/or chilling the harvested plants during their transit from the plant receiving zone to the plant releasing zone of the harvesting wheel. The harvested plants may be released in groups from the harvesting wheel for bundling in bunches by a worker positioned on the vehicle adjacent the harvesting wheel. Alternatively, the plants may discharge from the wheel into a plant receiver equipped with a trimmer for trimming the tops from the plants. The described, presently preferred embodiment of the harvesting machine has a plurality of harvesting wheels for simultaneously harvesting the plants in a plurality of adjacent plant rows and seeding means for immediately reseeding the plant rows.
