Description
Die Erfindung betrifft eine Kartoffelerntemaschine mit über einem Rost laufender Schubtrommel.The invention relates to a potato harvester with a grate running over a grate Thrust drum.
Bei Kartoffelerntemaschinen dieser Art stellte sich der Mangel heraus, daß die Trommel in ihrem Durchmesser nicht verändert werden konnte, also der Abstand zwischen den umlaufenden Schubtrommelleisten und den Roststäben trotz verschiedener Siebbeschaffenheit des Bodens unveränderlich war. Dieser Mangel der Verstellbarkeit der Trommel verhinderte besonders bei leichten Böden die volle Anwendung der bei Kartoffelerntemaschinen dieser Art getroffenen Anordnung »5 der Verstellung des Rostes, da das Schwanken des Rostes nach oben durch den Schubtrommelumfang begrenzt war.In potato harvesters of this type, the defect was found to be that the drum could not be changed in their diameter, i.e. the distance between the circumferential push drum strips and the grate bars was invariable despite the different screen properties of the bottom. This lack of adjustability of the drum was particularly difficult on light soils the full application of the arrangement made in potato harvesters of this type »5 the adjustment of the grate, as the grate sways upwards due to the circumference of the pusher drum was limited.
Gemäß der Erfindung sind die vorderen Schubleistenenden wie auch die hinteren so Stützspeichen in ihren Nabenscheiben radial verschiebbar, während die hintere Nabenscheibe für die Stützspeichen gegenüber der festsitzenden vorderen Nabenscheibe auf der Trommelwelle verdreh- und verschiebbar be- »5 festigt ist.According to the invention, the front thrust strip ends as well as the so rear support spokes in their hub discs radially displaceable, while the rear hub disc for the support spokes against the fixed front hub disc against rotation on the drum shaft and is displaceable loading "5 solidifies.
Auf der Zeichnung ist der Erfindungsgegenstand in drei Abbildungen dargestellt, von denen die Abb. ι die Schubtrommel von hinten zeigt, während die Abb. 2 und 3 schematisch die Schubtrommel in Seitenansicht und Querschnitt mit den Schubleisten in zwei verschiedenen Stellungen zeigen.In the drawing, the subject of the invention is shown in three figures, of which the Fig. ι shows the thrust drum from behind, while Figs. 2 and 3 schematically show the push drum in side view and cross section with the push bars in two different positions.
Die Schubtrommelleisten »1 sind mit ihren vorderen, radial nach innen gebogenen Ehden Wi1 auf der Nabenscheibe μ radial verschiebbar mittels Schrauben s befestigt und werden an ihren hinteren Enden von Stützleisten ρ getragen, die in der Nabenscheibe M1 ebenfalls radial verschiebbar durch Schrau-■ ben J1 festgehalten werden. Die vordere Nabenscheibe μ sitzt fest auf der Trommelwelle/, während die hintere Nabenscheibe M1 verdreh- und verschiebbar gelagert und mittels Klemmschraube t feststellbar ist.The push drum bars »1 are attached with their front, radially inwardly bent Ehden Wi 1 on the hub disk μ radially displaceably by means of screws s and are supported at their rear ends by support bars ρ , which are also radially displaceable in the hub disk M 1 by screws ■ be recorded ben J 1 . The front hub disk μ is firmly seated on the drum shaft /, while the rear hub disk M 1 can be rotated and displaced and can be locked by means of a clamping screw t .
Die Verstellung des Schubtrommelumfanges geschieht nun in der Weise, daß die hintere Nabenscheibe M1 durch Lockern der Klemmschraube t gelöst wird, so daß sich die NabeM1 auf Welle/ verdrehen und verschieben kann. Nach Lockern der Schrauben s und J1 können die Schubleistenenden W1 und p entsprechend aus der Nabe herausgezogen oder hineingeschoben werden. Die Nabenscheibe It1 paßt sich dabei der neuen Stellung der Stützspeichen ρ an. Die Stellung wird dann durch Anziehen der Schrauben j, J1 und der Klemmschraube t festgestellt.The adjustment of the thrust drum circumference is now done in such a way that the rear hub disc M is 1 t achieved by loosening the clamping screw, so that the NabeM 1 rotate on shaft / and can move. After loosening the screws s and J 1 , the sliding strip ends W 1 and p can be pulled out of the hub or pushed in accordingly. The hub disk It 1 adapts itself to the new position of the support spokes ρ . The position is then determined by tightening the screws j, J 1 and the clamping screw t .
