Description

Den Gegenstand der Erfindung bildet eine Schneckenwalze, besonders zum Zerkleinern der auf einem bestellten Felde liegenden Erdbrocken. Sie zeichnet sich durch zwei hintereinander angeordnete Walzen mit Rippen nach Art eines mehrgängigen Gewindes aus, von denen die eine Walze rechts- und die andere Walze linksgängig ist.The subject of the invention forms a screw roller, especially for comminuting the Chunks of earth lying on a cultivated field. It is characterized by two arranged one behind the other Rolls with ribs in the manner of a multiple thread, one of which is a roller right-hand and the other roller is left-hand.

Die Zeichnung zeigt die Schneckenwalze von oben gesehen. In einem Rahmen α sind die beiden zum Teil hohlen Walzen b und c drehbar gelagert. Beide Walzen sind mehrgängig mit entgegengesetzt gerichteten Steigungen. Um längere oder kürzere Walzen zu verwenden, sind diese aus mehreren Stücken zusammengesetzt. Das Zusammenhalten der einzelnen Stücke geschieht durch Schrauben d. Damit diese Schrauben nicht allein den ganzen Druck 'aufzunehmen haben, können zwischen den einzelnen Stücken federnde Zickzack-Stahlringe eingefügt oder Klauenkupplungen o. dgl. vorgesehen sein. Das Gerät dient zur Bearbeitung sowie zur Nacharbeit eines besäten Feldes, besonders zum Zerkleinern von Erdbrocken. Da beide Walzen entgegengesetzte Gewindesteigungen haben, wird das Feld so geschnitten, daß die Schnittlinien sich kreuzen. Auch wird der Boden durch diese Kreuzarbeit besser als durch die übliche Ringelwalze angedrückt. Die Gewindegänge sind etwa 6 cm hoch.The drawing shows the screw roller seen from above. The two partially hollow rollers b and c are rotatably mounted in a frame α. Both rollers are multi-thread with oppositely directed slopes. In order to use longer or shorter rollers, these are composed of several pieces. The individual pieces are held together by screws d. So that these screws do not have to absorb all the pressure on their own, resilient zigzag steel rings can be inserted between the individual pieces or claw couplings or the like can be provided. The device is used for processing and reworking a sown field, especially for breaking up chunks of earth. Since both rollers have opposite thread pitches, the field is cut so that the cutting lines cross. This cross work also presses the ground down better than the usual curling roller. The threads are about 6 cm high.
