A potato lifter, but also being a lifter capable of lifting other especially subterranean vegetation products, such as celery roots, carrots, bulbs, edible onions, etc., the lifter being of the kind comprising an in the ground, under the products, led cutting member and a conveyor positioned behind the cutting member for the upwards guiding of the products is described. A number, and at least one, mainly with plain, smooth or comparatively featureless surface shaped delivery roll or rolls (5, 6, 7, 8) is (are) positioned between the rear edge of the cutting member(1, 2, 3, 4) and the conveyor (9). The delivery rolls, having preferably equal diameters and being driven with a circumference velocity of about the same size as the forward drive velocity of the potato lifter, are positioned rotatable around mainly horizontal axes and, when more than one, positioned rather close together and mutually parallel. The damage introduced at the mechanical lifting to the potatoes is exquisitely low.
A lifter for lifting subterranean vegetation products, the lifter comprising supporting wheel means for supporting the lifter, unearthing means adapted to be inserted under the vegetation products for cutting a ribbon of earth containing subterranean vegetation products to be lifted by the lifter, an endless moving conveyor means positioned behind the unearthing means for receiving the ribbon of earth containing subterranean vegetation products and upwardly guiding the lifted vegetation products, said conveyor means having a structure which permits earth to fall down through the conveyor means to the ground while upwardly conveying the vegetation products, more than one delivery roll means, each having a smooth cylindrical outer surface, disposed from a rear edge of the unearthing means to a front edge of the conveyor means, said delivery roll means being parallel to one another and all located in rather close proximity to one another for delivering vegetation products and earth from the unearthing means to the conveyor means, and drive means for rotationally driving at least one of said delivery roll means.
A lifter for lifting subterranean vegetation products, the lifter comprising unearthing means adapted to be inserted under the vegetation product, an endless moving conveyor means positioned behind the unearthing means for upwardly guiding the vegetation products while permitting earth to fall therethrough to the ground, more than one delivery roll means, each having a smooth cylindrical outer surface, the roll means being all located in rather close proximity to one another and disposed from a rear edge of the unearthing means to a front edge of the conveyor means for conveying vegetation products and earth from the unearthing means to the conveyor means, means for driving at least one delivery roll means, a further conveyor means extending over at least a portion of the delivery roll means, said further conveyor means cooperating with said delivery roll means to assist in conveying the vegetation products.
