A mechanical berry harvester and a method for harvesting berries in the field is provided. The mechanical harvester includes a framework, collectors, spring elements, pulleys and belts. The collectors are configured to collect berries fallen from branches of the berry bush. Each spring element is connected to the framework and a collector. Each pulley is connected to a spring element and a collector. Each belt has an inner face and an outer face, and the inner faces of the belts are in contact with the pulleys. When the trunk of a berry bush comes in contact with a portion of the adjacent belts, the spring element(s) connected to the portions of the adjacent belts in contact with the trunk are each configured to independently compress and create a gap between the adjacent belts. |

1. A mechanical harvester for harvesting berries from a bush in a field, the bush having a trunk, branches connected to the trunk, and berries attached to the branches, the mechanical harvester comprising:
a framework; a first collector, configured to collect berries fallen from branches of a bush; a first spring element, connected to the framework and the first collector; a first pulley, connected to the first spring element and the first collector; a first belt, wherein the first belt has an inner face and an outer face, and wherein a portion of the inner face of the first belt is in contact with the first pulley; a second collector, configured to collect berries fallen from branches of the bush; a second spring element, connected to the framework and the second collector; a second pulley, connected to the second spring element and the second collector; and a second belt, wherein the second belt has an inner face and an outer face, wherein a portion of the inner face of the second belt is in contact with the second pulley, and the outer face of the first belt is adjacent to the outer face of the second belt,
wherein, when the trunk of a bush is in contact with a portion of the outer face of the first belt and an adjacent portion of the outer face of the second belt, the first spring element and the second spring element are each configured to independently compress and create a gap between the portion of the outer face of the first belt and the adjacent portion of the outer face of the second belt in contact with the trunk. |
