KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Pflug A, dessen Streichbrett hinten im Loth steht, legt, unterstützt durch einen Krautheber, einen Kartoffelwall derart um, dafs er senkrecht zur Erde steht, das Kartoffelkraut daher platt auf der Erde liegt. Der unmittelbar seitlich dahintergehende Cylinder fährt dabei auf das Kartoffelkraut hinauf und drückt dasselbe fest an die Erde, so dafs ein Hervorziehen unmöglich ist. Zu derselben Zeit durchfurcht das Zinkenrad B den umgelegten Kartoffelwall und reifst dabei die Kartoffeln vom Kraut ab, während die Erde durch die Zinken durchfällt und liegen bleibt.The plow A, whose mouldboard is in the back of the pile, with the help of a haulm lifter, lays down a potato wall in such a way that it is perpendicular to the earth, so the potatoes lie flat on the earth. The cylinder immediately behind it moves up onto the potato tops and presses it firmly against the earth, so that it is impossible to pull it out. At the same time, the tine wheel B furrows the folded potato wall and ripens the potatoes from the leaves, while the earth falls through the tines and remains.
Die Kartoffeln nebst Steinen fallen zunächst in die Schneckengänge des konischen Siebes C und werden durch dieselben in den inneren Cylinder E befördert, woselbst die gröfseren Kartoffeln und Steine verbleiben, die kleineren aber in den äufseren Cylinder F fallen. Erstere wie letztere werden durch Elevatorbecher G (2 und 1) in die entsprechenden Oeffnungen des Trichters H geworfen, durch welchen sie in die vom Ventilator J auslaufenden Kasten fallen. Der Boden O der Kasten ist ansteigend und wird durch das Zahnrad Q. und die Feder P geschüttelt, so dafs sich Kartoffeln und Steine in einer fortwährenden Bewegung befinden. Dabei werden sie durch den vom Ventilator J verursachten Luftzug in der Weise sortirt, dafs der Wind die leichteren Kartoffeln bergan rollt, während die schwereren Steine dem Wind entgegen bergab rollen und zur Erde fallen. Die Kartoffeln gelangen nach Verlassen der Kasten in die Rinne K und von hier in die Körbe L. The potatoes and stones first fall into the screw flights of the conical sieve C and are conveyed through the same into the inner cylinder E , where the larger potatoes and stones remain, but the smaller ones fall into the outer cylinder F. The former and the latter are thrown through elevator buckets G (2 and 1) into the corresponding openings of the funnel H , through which they fall into the boxes running out from the fan J. The bottom O of the box rises and is shaken by the gear wheel Q. and the spring P, so that the potatoes and stones are in constant motion. In doing so they are sorted by the draft caused by the fan J in such a way that the wind rolls the lighter potatoes uphill, while the heavier stones roll downhill against the wind and fall to the earth. After leaving the box, the potatoes enter channel K and from here into baskets L.
Das Zinkenrad B wird durch die Schneckenräder M, der Ventilator J durch die Stirnräder N angetrieben.The toothed wheel B is driven by the worm wheels M, the fan J by the spur wheels N.
Die rechte Seite der Maschine wird von einem gewöhnlichen Wagenrad getragen. :The right side of the machine is carried by an ordinary wagon wheel. :
