PATENTAMT.PATENT OFFICE.

Bei den bekannten Rübenköpfern, bei welchen das Köpfmesser an einem auf- und niederbeweglichen Gleitschuh oder an dessen Schaft befestigt ist, welcher sich nach Mafsgabe der Bodenunebenheiten oder des Hervorstehens der Rüben aus dem Boden hebt, ist dieser Gleitschuh oder dessen Schaft entweder derartig gelenkig am Fahrzeug befestigt, dais er vorausgeschoben wird, oder er bewegt sich in einer am Fahrzeuge angebrachten Führung senkrecht auf und nieder. Auch ist es bekannt, das nachgebende Messer nachzuschleppen. Bei derartigen Anordnungen ist aber ein auf- und abgehender Schaft nicht vorhanden, auch ist die Wirkung des einarmigen Hebels eine wesentlich andere, als bei dem vorliegenden doppelarmigen Hebel. Das Vorausschieben des nur gelenkig am Fahrzeuge befestigten Gleitschuhes oder die ungelenkige senkrechte Führung des Gleitschuhschaftes und mithin auch des Köpfmessers hat den Nachtheil, dafs der Gleitschuh, wenn er auf eine höher aus dem Boden ragende Rübe auf trifft, oder noch mehr, wenn der Rübenacker in der Fahrtrichtung Gefalle hat, hängen bleibt, sich in den Boden einbohrt oder sich in seiner Führung derart seitlich einklemmt, dafs er bei seinem Auftreffen auf Unebenheiten oder auf Rüben überhaupt nicht gehoben wird, sondern entweder von der Rübe seitlich abgleitet oder· dieselbe unterhalb des abzuschneidenden Kopfes beschädigt. Auch hat ein derartiges häufiges Hängenbleiben Zeit- und Kraftverluste zur Folge und der eigentliche Zweck des nachgiebigen Gleitschuhes, die Rübenköpfe in stets gleichmäfsiger Stärke abzuschneiden, wird nicht bei allen zu erntenden Rüben erfüllt.In the known beet toppers, in which the topping knife is attached to a sliding shoe that can be moved up and down or to its shaft is attached, which depends on the unevenness of the ground or the protrusion of the Lifts beets out of the ground, this sliding shoe or its shaft is either such articulated to the vehicle so that it is pushed ahead, or it moves in a guide attached to the vehicle vertically up and down. It is also known dragging the yielding knife. In such arrangements, however, is an up and there is no outgoing shaft, and the effect of the one-armed lever is essential different than with the present double-armed lever. Advancing the only articulated sliding shoe attached to the vehicle or the awkward vertical guidance of the Shoe shaft and therefore also the head knife has the disadvantage that the shoe, if it hits a beet protruding higher from the ground, or even more if the Beet field has a slope in the direction of travel, gets stuck, bores itself into the ground or it gets jammed laterally in its guide in such a way that it hits bumps on it or is not lifted at all on beets, but either slides sideways from the beet or below it of the head to be cut is damaged. Such frequent getting stuck also has time- and power losses as a result and the actual purpose of the flexible sliding shoe, To cut off the beet heads in an always uniform thickness is not to be harvested from all Beets met.

Ein weiterer Nachtheil der meisten bisher bekannten Rübenköpfmaschinen besteht darin, dafs sich die Zwischenräume zwischen den beweglichen Theilen mit dem abgeschnittenen Rübenkraut u. s. w. verstopfen und so den Gang der Maschine hindern können, da dann angehalten und die Vorrichtung vom Rübenkraut befreit werden mufs.Another disadvantage of most of the previously known beet topping machines is that that the interstices between the movable parts become with the cut off Turnip tops and so on can clog and thus prevent the machine from running stopped and the device must be freed from beet weeds.

Nach vorliegender Erfindung sollen alle diese Nachtheile dadurch beseitigt werden, dafs die Führung, in welcher der Schaft des Gleitschuhes auf- und niederbeweglich hängt, am Gestell eines fahrbaren Ackergeräthes in oben nach rückwärts geneigter Lage befestigt wird. Bei einer derart abgeänderten Rübenköpfmaschine weicht der Gleitschuh bei jedem Widerstände, den er in der Zugrichtung auf dem Acker findet, nach rückwärts aus, so dafs ein Festbohren des Gleitschuhes im Boden oder ein Festklemmen desselben in seiner Führung bezw. ein Beschädigen oder zu tiefes Abschneiden der Rübe nicht mehr stattfinden kann.According to the present invention, all these disadvantages are to be eliminated by the fact that the Guide, in which the shaft of the sliding shoe hangs up and down movable, on Frame of a mobile agricultural implement is attached in a position tilted backwards at the top. With a beet topping machine modified in this way, the sliding shoe gives way with every resistance, which he finds in the direction of pull in the field, backwards, so that a fixed boring the sliding shoe in the ground or clamping the same in its leadership BEZW. the beet can no longer be damaged or cut too deeply.

Wird aufserdem wie bei der vorliegender Erfindung zu Grunde gelegten Ausführungsfonn der Gleitschuh mit dem unteren Ende seines Schaftes wie ein doppelarmiger Hebel, im Gegensatze zu den einarmigen Hebeln der eingangs erwähnten nachschleppenden Messer, drehbar verbunden, so hebt sich bei seinem Auftreffen auf ein Hindernifs oder aur eine Rübe zunächst sein vorderes Ende, woraufIs also based on the embodiment used in the present invention the sliding shoe with the lower end of its shaft like a double-armed lever, In contrast to the one-armed levers of the dragging knives mentioned at the beginning, rotatably connected, it lifts itself up when it hits an obstacle or a just one First turnip its front end, whereupon

Claims

the sliding shoe, when it reaches the top, adjusts itself horizontally in order to lift the rear end when sliding off the obstacle. As a result, the safety against drilling into the glide shoe in the field or against damage to the beets protruding from the ground by the front part of the glide shoe is increased considerably and the beet weeds are turned over by the glide shoe immediately before the beet head is cut off. An embodiment of the present invention is shown in the drawing on a mobile agricultural implement, as it is usually used for digging beets from the ground; however, the plowshares performing the latter work are omitted from the drawing for the sake of clarity. Fig. Ι shows the whole device in view and at the moment in which the sliding shoe hits a beet. FIG. 2 is the outline of FIG. 1, and FIG. 3 shows the subject matter of the invention viewed from the front in a cross-section through the mobile agricultural implement; Fig. 4 shows the actual beet topper from the front and Fig. 5 from the side and partly in section; Fig. 6 finally illustrates the working position of the beet topper, in which the knife begins to cut. In this embodiment, two beet heads are fastened to the longitudinal bar α of the mobile farm equipment so that they can be adjusted by means of wrought-iron holders b in the required inclination. After loosening the fastening screw c, you can turn the two holders b around screw c and thereby incline the beet heads more or less to the ground. After loosening the clamping screws d, the guide e of the beet tops can also be set higher or lower on the holders b. A rod hangs loosely in the guide e; an adjustable stop g prevents it from falling out. At the lower end of the rod f, the sliding shoe h is rotatably connected to it by means of the bolt i and at the rear end of the curved sliding shoe h is by means of the screw clamp k the head knife m adjustable. The knife m is designed in such a way that the cut tuft of cabbage and head can stay on the beet or fall backwards or sideways. The weight of the sliding shoe h is measured and distributed in such a way that it is in the The rest position adjusts horizontally or almost horizontally in spite of its rearward load. Any number of the new beet topper can be attached to a mobile agricultural implement. You only have to make sure that this is done at intervals which correspond to the distances between the rows of beets -Expectations:

1. Beet topper, in which a shoe sliding over the ground and the beets adjusts the topping knife by its raising and lowering according to the protrusion of the beets, characterized in that the guide fej, in which the sliding shoe (hj with its shaft (f) is located) moved up and down, is attached to the mobile agricultural implement at the top in a rearwardly inclined position, for the purpose of enabling the sliding shoe to evade backwards when it hits an obstacle located in its roadway and thereby to allow it to be clamped in its guide or to be drilled in the field or to prevent damage to the beets.

2. embodiment of the under ι. characterized beet topper, in which the sliding shoe (h) is articulated like a double-armed lever with the lower end of its shaft that can be moved up and down, for the purpose of increasing the security against pinching the sliding shoe and against damage to the beets by the fact that the The sliding shoe rotates around its joint accordingly when sliding over the obstacle or the turnip. ;

3. Embodiment of the beet topper marked under 1., in which the up and down movable shaft of the sliding shoe hangs in its guide with a stop (g) which can be adjusted in its longitudinal direction.

4. Embodiment of the beet head marked under 1., in which the after backward inclined guide for the shaft of the sliding shoe on the Ackergeräth such attached so that it can be adjusted so that it can be inclined more or less.
